Description

Technical Field

[0001] The invention belongs to the technical field of assembly equipment, and in particular relates to automatic sealing rivet assembly equipment. Background Art

[0002] In order to meet the needs of automotive aluminum casting sealing cover plates and other parts that cannot be processed with threads, pull riveting or press riveting sealing rivets are required. For example, patent CN219975070U discloses a pull riveting rivet, press riveting rivet and sealing riveting structure, that is, the composition of the sealing rivet is as follows: Figure 1 As shown in FIG. 1 , the sealing rivet comprises a rivet 1, a screw 2 and a sealing ring 3. The rivet 1 is hexagonal on the outside, and a blind hole 102 with a threaded section 101 is provided inside the rivet 1. A flange 105 at the tail of the rivet 1 is provided with a sealing groove 103 capable of accommodating the sealing ring 3. The screw 2 can cooperate with the threaded hole, and an inner polygonal groove 201 is provided at the head of the screw 2. The assembly of the sealing rivet product 10 is as shown in FIG. Figure 1 As shown in FIG. 2 , when assembling the sealing rivet, the screw 2 needs to be screwed into the blind hole 102 of the rivet 1 and matched with the threaded section 101, and the sealing ring 3 is assembled in the sealing groove 103 of the rivet 1. The application cross-sectional view and appearance view of the sealing rivet are shown in FIG. Figure 1 As shown in figure c, when the sealing rivet is riveted on the sheet metal 4, one side of the sheet metal 4 is tightly fixed by the convex part 104 formed by the outward protrusion deformation of the squeezed rivet 1 material, and the anti-deformation strength of the material at the threaded section 101 of the rivet 1 is improved by the cooperation of the screw 2 and the threaded section 101, so as to protect the threaded section 101 and meet the requirements of the thread gauge detection. The sealing ring 3 is located between the other side of the sheet metal 4 and the flange 105 of the rivet 1 to provide effective sealing; therefore, before the riveting process, the sealing rivet 1 needs to be assembled with the rivet 1, the screw 2 and the sealing ring 3, but the main problem is that the existing assembly equipment cannot assemble continuously and automatically, and multiple workers are required to cooperate with tooling or semi-automatic equipment to complete the assembly of the components in pairs, and finally the assembly and detection of the three. The assembly involves multiple processes and the transfer of semi-finished products that have not completed the final assembly, which not only affects the production efficiency, but also has high labor intensity for the personnel, and is prone to missing during the assembly process, which leads to poor production.

[0003] Secondly, there is a problem that the flat thickness of the tail of the sealing rivet after assembly cannot meet the assembly accuracy requirements. For example, for rivets with a flange thickness of 3mm, the processing accuracy can only be guaranteed to be ±0.2mm. When the sealing rivet is riveted to the product and has high requirements for flatness, the rivet is directly assembled and its own accuracy cannot meet the application requirements.

[0004] In addition, when inspecting sealing rivets, defective products from each process cannot be individually eliminated. For example, when there is foreign matter in the blind hole of the rivet, it may cause the effective depth of the thread to be unqualified, the screw or thread may be stripped, and the sealing ring may not be tightly attached to the sealing groove. The inspection efficiency is poor, and it is easy to miss inspections and cause production defects. It is also not conducive to the subsequent differentiation and rework of the process products.

For those skilled in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0057] The existing assembly equipment cannot realize the continuous automatic assembly of rivets, screws and sealing rings of sealing rivets, and it is easy to cause missing assembly. Figures 2 to 4As shown, it is a preferred embodiment of the sealing rivet automatic assembly equipment of the present invention, the sealing rivet automatic assembly equipment comprises a transport module 5, along the transport direction of the transport module 5 are respectively provided with a rivet feeding station 6, a plurality of processing stations 7, and a blanking station 8, the transport module 5 comprises a plurality of rivet transport mechanisms 501 that can reciprocate between adjacent rivet feeding stations 6 and processing stations 7 / between adjacent processing stations 7 / between adjacent processing stations 7 and blanking stations 8, a plurality of processing stations 7 are provided with a screw assembly mechanism 9 and a sealing ring assembly mechanism 11, The screw assembly mechanism 9 includes a screw feeding station 901, a screw locking mechanism 902, a first rivet positioning fixture 903 and a screw defective product rejection port 904. The screw locking mechanism 902 can reciprocate and move up and down between the screw feeding station 901 and the first rivet positioning fixture 903. The rivet 1 positioning fixture and the screw defective product rejection port 904 are arranged in sequence along the conveying direction of the conveying module 5. Along the conveying direction of the conveying mechanism, a sealing ring detection mechanism 12 and a sealing ring defective product rejection port 13 are arranged in sequence behind the sealing ring assembly mechanism 11.

[0058] Processing Figure 1 Take the sealing rivet shown as an example. Figure 4 As shown, taking the screw assembly mechanism 9 being located in front of the sealing ring assembly mechanism 11 in the conveying direction of the conveying module 5 as an example, the rivet 1 is conveyed to the processing station 7 of the next process by the rivet conveying mechanism 501 of the conveying module 5 at the rivet feeding station 6, for example, the rivet 1 is automatically conveyed to the rivet 1 positioning fixture of the screw assembly mechanism 9 by the rivet conveying mechanism 501, and the screw 2 is conveyed by the screw locking mechanism 902 at the screw feeding station 901, transferred to the first rivet positioning fixture 903, and the screw 2 is assembled in the blind hole 102 of the rivet 1 by locking and In cooperation with the threaded segment 101, the screw locking mechanism 902 can be used to determine whether the screw 2 is missing, and then the rivet transporting mechanism 501 can be controlled to transport the rivet 1 assembled with the screw 2 from the first rivet positioning fixture 903 to the next workstation again. For example, when corresponding to the defective screw rejection port 904, the rivet 1 can be loosened to allow defective products that cannot be assembled with the screw 2 due to foreign matter in the blind hole 102, slippage of the screw 2 and the threaded segment 101, etc. to fall into the defective screw rejection port 904 and be rejected separately, so as to avoid missing the screw 2.

[0059] The rivet 1 assembled with the screw 2 is transported and transferred to the next processing station 7 by the rivet transport mechanism 501. For example, when it corresponds to the sealing ring assembly mechanism 11, the sealing ring 3 is further assembled on the rivet 1 through the sealing ring assembly mechanism 11, and then the rivet transport mechanism 501 transports and transfers the rivet 1 assembled with the screw 2 and the sealing ring 3 to the next station. For example, when it corresponds to the sealing ring detection mechanism 12, the sealing ring detection mechanism 12 can be used to detect the presence of the sealing ring 3 to determine whether the sealing ring 3 is missing, and then the rivet transport mechanism 501 is controlled to transport again. The rivet 1 is transported from the sealing ring detection mechanism 12 to the next workstation, such as the corresponding sealing ring defective product rejection port 13. The rivet 1 can be loosened so that the defective products that cannot be assembled with the sealing ring 3 due to the breakage of the sealing ring 3, the failure of the sealing ring assembly mechanism 11, etc., fall into the sealing ring defective product rejection port 13 and are rejected separately, so as to avoid the leakage of the sealing ring 3. Finally, the rivet 1 is transported by the rivet transport mechanism 501, and the sealing rivet assembled with the rivet 1, screw 2 and sealing ring 3 is transported to the unloading station 8 for assembly.

[0060] On the one hand, the above-mentioned sealing rivet automatic assembly equipment uses the rivet conveying mechanism 501 of the conveying module 5 to move between adjacent workstations to convey the rivet 1, and sets the screw assembly mechanism 9 and the sealing ring assembly mechanism 11 along the conveying direction to respectively perform the assembly processing of the screw 2 and the sealing ring 3, so that the automatic locking of the screw 2, the automatic assembly of the sealing ring 3 and the automatic unloading of the good product after the parts are loaded can be realized, and the sealing rivet can be automatically assembled continuously, and multiple processes are integrated into one device for continuous production. It is no longer necessary to transfer the semi-finished products that have not completed the final assembly, so as to reduce the labor intensity of the personnel, and the semi-finished products can be saved from repeated loading and unloading processes, which greatly improves the work efficiency. On the other hand, the above-mentioned sealing rivet automatic assembly equipment The dynamic assembly equipment determines whether the screw 2 is missing through the screw locking mechanism 902, and sets a screw defective rejection port 904 after the screw 2 is locked along the conveying direction, and sets a sealing ring detection mechanism 12 and a sealing ring defective rejection port 13 after the sealing ring 3 is assembled. This can not only avoid production defects caused by missing and missing inspection of screws 2 and sealing rings 3 during the automatic assembly process, but also can distinguish, collect and rework semi-finished products without assembled screws 2 or sealing rings 3 through automatic separate rejection, so as to improve work efficiency and reduce production waste, thereby solving the problem of continuous automatic assembly of rivets 1, screws 2 and sealing rings 3 of sealing rivets, effectively improving production efficiency and reducing production defects.

[0061] like Figures 2 to 5 As shown, further, the rivet feeding station 6 is provided with a plate pusher 14 , and the plate pusher 14 is provided with a rivet feeding track 144 that can cooperate with the rivet 1 , and the rivet feeding track 144 can correspond to the rivet transport mechanism 501 .

[0062] For example: Figure 5As shown, the bottom shape of the rivet 1 is hexagonal. A plurality of rivets 1 to be assembled are manually poured into the push plate machine bin 141. The push plate machine motor 142 pushes the plurality of rivets 1 to the rear end of the rivet feeding track 144 by gradually lifting the push plate 143. The slot width of the rivet feeding track 144 is designed according to the hexagonal width of the rivet 1. The first linear feeder 145 of the push plate machine 14 drives the rivet feeding track 144 to vibrate continuously. When the hexagonal position of the bottom of the rivet 1 is consistent with the slot width, the rivet 1 falls into the rivet feeding track 144 and It is supported and transported forward until it is transported to the front end exit position to be transported by the rivet handling mechanism 501. By adding a push plate machine 14 and a rivet loading track 144 that cooperates with the rivet 1, it is more convenient to load the rivets 1 in sequence than by loading the rivet 1 rack. At the same time, the rivets 1 are automatically arranged in a vertical position and angle to be coordinated with the rivet handling mechanism 501 and each rivet 1 positioning fixture, thereby further improving the processing efficiency. The push plate 143 loading structure is adopted to avoid damage to the product coating caused by multiple vibrations of the product.

[0063] Further, such as Figure 5 As shown, the plate pusher 14 is provided with a blowing mechanism, which corresponds to the rivet feeding track 144 and the return port 146 of the plate pusher 14; for example: the blowing mechanism includes a photoelectric switch 147 and a blowing nozzle 148 corresponding to the rivet feeding track 144. When the rivet 1 that fails to be inserted into the rivet feeding track 144 is transported forward along the rivet feeding track 144 to the position of the photoelectric switch 147, the photoelectric switch 147 transmits the model to control the blowing nozzle 148 to eject air, so that the rivet 1 that fails to be inserted into the rivet feeding track 144 hangs down from the rivet feeding track 144 and falls back onto the material trough of the plate pusher 14 along the return port 146, which can further reduce the feeding failure of the rivet 1 and improve the automation efficiency.

[0064] like Figures 2 to 6 As shown, further, the transport module 5 includes a first driving mechanism, and the first driving mechanism is used to drive a plurality of rivet transport mechanisms 501 to move back and forth synchronously at adjacent workstations.

[0065] For example: Figure 6 As shown, the first driving mechanism includes a first linear module 502, and a plurality of rivet handling mechanisms 501 are installed at intervals on the sliding block of the first linear module 502. The first linear module 502 drives all rivet handling mechanisms 501 to move left and right synchronously to realize synchronous reciprocating movement between adjacent workstations. Through synchronous drive, continuous processing of the upper and lower processes can be realized, thereby improving the processing rhythm and efficiency. Similarly, according to the size of each mechanism and the workstation design of the assembly equipment, the first driving mechanism can also be set to a variety of mobile handling driving modes such as arc-shaped, U-shaped, circular, and circular modules, which can be set according to needs.

[0066] Furthermore, the rivet transport mechanism 501 includes a second driving mechanism and an automatic clamp, wherein the second driving mechanism is used to drive the automatic clamp to move up and down, and the automatic clamp is used to clamp the rivet 1 .

[0067] For example: Figure 6 As shown, the second driving mechanism includes a first cylinder 503 arranged on the first linear module 502, and the automatic clamp is a cylinder clamp 504, which is installed on the slide of the first cylinder 503. The cylinder clamp 504 is provided with a clamping arm 505 that can cooperate with the top flange 105 of the rivet 1. After the first linear module 502 drives the first cylinder 503 to move left and right, the first cylinder 503 can drive the cylinder clamp 504 to move downward, so that the cylinder clamp 504 can move downward. 4 is close to the rivet 1 of the corresponding station, the rivet 1 is clamped and then driven to move upward by the cylinder clamp 504 to take out the rivet 1, or the clamping of the rivet 1 is released to place the rivet 1 on the corresponding station, so that the cylinder clamp 504 is unloaded for clamping again. The structure is simple, and the rivet 1 can be transported and the loosening of each rivet transporting mechanism 501 can be independently controlled to load the rivet 1, assemble the screw 2 and the sealing ring 3, remove the defective products and unload the good products, further simplifying the control and improving the processing efficiency.

[0068] Aiming at the problem that the thickness of the tail plane of the sealing rivet after assembly cannot meet the assembly accuracy requirements, such as Figures 2 to 4 and Figure 7 As shown, further, a plurality of processing stations 7 are provided with a rivet pressing mechanism 15 located in front of the screw assembly mechanism 9 or the sealing ring assembly mechanism 11 .

[0069] For example: for the rivet 1 with a flange 105 thickness of 3mm, the processing accuracy can only be guaranteed to be ±0.2mm. When the sealing rivet is riveted to the product and has high requirements for flatness, a finishing function is added through the rivet pressing mechanism 15, which is used to perform secondary flattening processing on the tail size of the rivet 1 before the screw 2 or the sealing ring 3 is assembled to ensure that the dimensional accuracy is within the range of 2.8+0.05mm.

[0070] Furthermore, the rivet pressing mechanism 15 includes a second rivet positioning fixture 151 , a third driving mechanism, and a booster 154 , wherein the third driving mechanism is used to drive the second rivet positioning fixture 151 to move back and forth between the rivet transporting mechanism 501 and the booster 154 .

[0071] For example: Figure 7As shown, the second rivet positioning fixture 151 is provided with a positioning hole that cooperates with the bottom limit of the rivet 1, the third driving mechanism includes a second cylinder 152, and the booster 154 is a booster 154 with a booster cylinder 153. The second cylinder 152 is installed behind the booster 154, and the cylinder rod is connected to the second rivet positioning fixture 151. The second rivet positioning fixture 151 and the booster 154 are slidably matched. After the rivet transporting mechanism 501 moves leftward and downward and clamps the rivet 1 at the outlet position of the rivet feeding track 144, and transports it upward and rightward to the top of the second rivet positioning fixture 151, it can move downward and release the clamping to insert the rivet 1 into the positioning hole of the second rivet positioning fixture 151, as shown in FIG. Figure 8 As shown, the cylinder rod of the third driving mechanism contracts and drives the second rivet positioning fixture 151 to move to the bottom of the booster cylinder 153, and the booster cylinder 153 descends to squeeze the top surface of the rivet 1 to flatten and tighten it, and then the booster cylinder 153 rises and returns to its original position, and then the cylinder rod extends and drives the second rivet positioning fixture 151 to return to its original position. Figure 7 state, so as to be taken away again by the rivet transport mechanism 501. Through the offset driving and the whole pressing, the rapid automatic processing can be realized, the continuous transport of the rivets 1 is convenient, and the production efficiency is further improved.

[0072] like Figures 2 to 4 As shown, further, several processing stations 7 are provided with a rivet pressing mechanism 15, a rivet height detection mechanism 16 and a rivet height defective rejection port 17 which are sequentially arranged in front of the screw assembly mechanism 9 or the sealing ring assembly mechanism 11.

[0073] For example: the rivet height detection mechanism 16 and the rivet height defective rejection port 17 are arranged in front of the screw assembly mechanism 9. After the rivet 1 is secondarily leveled by the rivet pressing mechanism 15, the defective products whose height accuracy is still unqualified can be detected by the rivet height detection mechanism 16, and then the defective products can be promptly rejected through the rivet 1 defective rejection port to avoid production defects caused by missed inspections. By separately rejecting the defective products in the secondary leveling process, it is beneficial to distinguish and rework the process products in the subsequent process.

[0074] Fig. 9 As shown, further, the rivet height detection mechanism 16 includes a fourth driving mechanism, a displacement sensor 162 and a third rivet positioning fixture 163, and the fourth driving mechanism is used to drive the displacement sensor 162 to move up and down relative to the third rivet positioning fixture 163.

[0075] For example, the fourth driving mechanism includes a third cylinder 161, the displacement sensor 162 is a spring self-resetting displacement sensor 162 and is installed on the slider of the third cylinder 161, the third rivet 1 fixture is provided with a positioning hole matched with the bottom of the rivet 1, the rivet 1 height defective flat rejection port is a rejection channel, and a corresponding receiving basin is provided in the whole machine chassis below the rejection channel. Then, the latter rivet transporting mechanism 501 can similarly transport the rivet 1 leveled in the second rivet positioning fixture 151 to the third rivet positioning fixture 163, and at the same time, the former rivet transporting mechanism 501 transports the next rivet 1 from the rivet feeding track 144 to the second rivet positioning fixture 151 again, and the rivet When the nail adjustment and pressing mechanism 15 is working, the fourth driving mechanism, i.e., the third cylinder 161, drives the spring self-resetting displacement sensor 162 to descend and contact the rivet 1, detects the height of the rivet 1 to determine whether the height of the rivet 1 is qualified and transmits a signal to the control terminal. If qualified, the next rivet conveying mechanism 501 conveys the detected rivet 1 to the screw 2 assembly station, and keeps it clamped when passing through the rivet height defective rejection port 17. If unqualified, the clamping is released when passing through the rivet height defective rejection port 17, and the rivet 1 can automatically fall into the centralized collection, so as to realize rapid and automatic detection of the height of the rivet 1 and 100% detection of the height after finishing. The rivet 1 with poor height is automatically and separately rejected, thereby improving work efficiency.

[0076] like Figures 2 to 4 and Figures 10-11 As shown, further, the screw loading station 901 is provided with a screw feeder 905 and a separator 906.

[0077] For example: multiple screws 2 can be manually poured into the hopper of the screw feeder 905, and the screws 2 can be transported one by one and arranged in position through the separator to realize automatic loading of the screws 2. The screw 2 rack structure can be used for batch automatic loading, further improving production efficiency.

[0078] Furthermore, the separator 906 includes a rotating separation disc 907, and the separation disc 907 is provided with a screw feed opening 908 corresponding to the screw feeder 905, for example, Fig.10 As shown, the screw feeder 905 is provided with a screw feeding track 919, which can blow out the screws 2 and convey them horizontally in sequence. Fig.11 As shown, the separation disc 907 of the separator 906 is driven by a motor to rotate around a horizontal axis. The separation disc 907 is provided with a plurality of spaced screw feeding ports 908 for staggered loading of the screws 2. When the screw feeding ports 908 are aligned with the screw loading track 919, the screws 2 are transported forward horizontally and can be inserted into the screw feeding ports 908. By rotating the separation disc 907, a screw 2 can be turned to a vertical state with the head of the screw 2 facing upward, so that the screw locking mechanism 902 can take the material.

[0079] like Figures 10-11 As shown, further, the screw locking mechanism 902 includes a fifth driving mechanism, an adsorption mechanism, an electric screwdriver 911 and a sixth driving mechanism. The fifth driving mechanism is used to drive the adsorption mechanism and the electric screwdriver 911 to reciprocate and move up and down between the screw feeding station 901 and the first rivet positioning fixture 903. The adsorption mechanism is used to adsorb the screw 2. The sixth driving mechanism is used to drive the lower end of the electric screwdriver 911 to extend into the adsorption mechanism and move up and down. The first rivet positioning fixture 903 is provided with a limiting mechanism, and the limiting mechanism is used to limit the rotation of the rivet 1.

[0080] For example: the fifth driving mechanism includes a second linear module 909 and a fourth cylinder 910, and the fourth cylinder 910 is installed on the slide of the second linear module 909 through a first mounting plate 914. The adsorption mechanism includes an adsorption nozzle 913, and the sixth driving mechanism includes a fifth cylinder 912. The adsorption nozzle 913 and the fifth cylinder 912 are installed through a second mounting plate 915 that slides with the first mounting plate 914. The electric screwdriver 911 is a servo electric screwdriver 911, and the servo electric screwdriver 911 is installed through a third mounting plate 916 that slides with the second mounting plate 915. The lower end of the servo electric screwdriver 911 extends into the adsorption nozzle 913. The flat rejection port of the rivet 1 with poor height is a rejection channel, and a corresponding material receiving basin is provided in the whole machine chassis below the rejection channel. Fig.10 As shown, the second linear module 909 can be arranged in front and behind the rivet height detection mechanism 16 to make the structure and workstation design more compact so as to improve the production rhythm.

[0081] Furthermore, the limiting mechanism is a polygonal hole that also serves as a positioning hole for the rivet 1 and / or a top piece that can be telescopic relative to the positioning hole for the rivet 1.

[0082] For example, the first rivet positioning fixture 903 is provided with a positioning hole matched with the polygonal outer wall of the rivet 1, and a communicating side hole 917 is provided on the side of the positioning hole. The top piece of the limiting mechanism is the sixth cylinder 918, and the cylinder rod of the sixth cylinder 918 can extend into the side hole 917. Then, the working principle of screw 2 assembly and defective product detection includes:

[0083] The conveying principle is the same. The rivet conveying mechanism 501 can be moved to the positioning hole of the first rivet positioning fixture 903 after the rivet 1 height detection in the previous process. During the operation of the rivet pressing mechanism 15 and the rivet height detection mechanism 16, the rivet 1 assembly mechanism works synchronously, and the second linear module 909 drives the suction nozzle 913 and the electric screwdriver 911 to move as a whole to the screw feeding port 908 of the separation disk 907. The fourth cylinder 910 drives the suction nozzle 913 and the electric screwdriver 911 to descend as a whole. After the suction nozzle 913 is placed above the screw 2, the screw 2 is sucked. The fourth cylinder 910 drives the suction nozzle 913 and the electric screwdriver 911 to rise as a whole to take the screw 2 out of the screw 2 feeding port.

[0084] The second linear module 909 drives the suction nozzle 913 and the electric screwdriver 911 to move as a whole to the top of the rivet 1 of the first rivet positioning fixture 903. The fourth cylinder 910 drives the suction nozzle 913 and the electric screwdriver 911 to descend as a whole. The suction nozzle 913 releases the suction of the screw 2, so that the screw 2 falls into the blind hole 102 of the rivet 1. The cylinder rod of the sixth cylinder 918 extends into the side hole 917 to abut against the side wall of the rivet 1, and the positioning hole and the cylinder rod are used to limit the rotation of the rivet 1. The fifth cylinder 912 drives the lower end of the electric screwdriver 911 to descend in the suction nozzle 913 to contact the screw. 2, under the descending of the fifth cylinder 912 and the rotation drive of the electric screwdriver 911, the screw 2 is screwed into the threaded section 101 of the rivet 1 and tightened to lock the screw 2. After tightening, the cylinder rod of the sixth cylinder 918 contracts and no longer presses the rivet 1. The fifth cylinder 912 drives the electric screwdriver 911 to rise and reset. The fourth cylinder 910 drives the suction nozzle 913 and the electric screwdriver 911 to rise and reset. The second linear module 909 drives the suction nozzle 913 and the electric screwdriver 911 to move back to their original positions, so that the suction nozzle 913 is separated from the rivet 1 after the screw 2 is assembled.

[0085] Compared with other screw locking mechanisms 902, this adsorption and electric screwdriver 911 locking method can not only quickly realize the automatic batch loading and automatic locking of the screws 2 in sequence, but also because the electric screwdriver 911 can detect foreign matter in the blind hole 102, unqualified effective thread depth, screw 2 or thread slippage, when the rivet transporting mechanism 501 transports the rivet 1 after the screw 2 assembly process from the first rivet positioning fixture 903 to the sealing ring assembly mechanism 11 through the screw defective product rejection port 904, if the screw 2 is found to be unqualified in assembly, the clamping is released to allow the unqualified rivet 1 to fall into the screw defective product rejection port 904 for collection. If the screw 2 is found to be qualified in assembly, the rivet transporting mechanism 501 keeps clamping the rivet 1 when passing above the screw defective product rejection port 904, which can not only avoid missing assembly, but also reject the unqualified screw 2 to avoid the outflow of defective products.

[0086] like Figures 2 to 4 and Figures 12 to 15 As shown, further, the sealing ring assembly mechanism 11 includes a sealing ring feeding mechanism 111, a sealing ring conveying mechanism 112, a fourth rivet positioning fixture 113 and a sealing ring fitting structure 114, the sealing ring conveying mechanism 112 includes a seventh driving mechanism and a sealing ring expansion core 117, the seventh driving mechanism is used to drive the sealing ring expansion core 117 to reciprocate and move up and down between the sealing ring feeding mechanism 111 and the fourth rivet positioning fixture 113, the fourth rivet positioning fixture 113 can cooperate with the rivet conveying mechanism 501, the sealing ring fitting structure 114 includes an eighth driving mechanism and a sealing ring chuck 118, the eighth driving mechanism is used to drive the jaws 135 of the sealing ring chuck 118 to move up and down in the fourth rivet positioning fixture 113.

[0087] For example: Fig.13 As shown, the sealing ring feeding mechanism 111 includes a vibration plate 119, a sealing ring feeding track 120, and a second linear feeder 121. The sealing ring feeding track 120 is located at the discharge port of the vibration plate 119. The second linear feeder 121 is used to drive the sealing ring feeding track 120 to vibrate and transport the sealing ring 3 forward. The seventh driving mechanism includes a seventh cylinder 115 and an eighth cylinder 116. The seventh cylinder 115 is installed on the frame. The cylinder rod of the seventh cylinder 115 is connected to a fourth mounting plate 122 that slides with the frame. The eighth cylinder 116 is installed on the fourth mounting plate 122. The cylinder rod of the eighth cylinder 116 is connected to a fifth mounting plate 123 that slides with the fourth mounting plate 122. The sealing ring expansion core 117 is installed on the fifth mounting plate 123 through a bracket; as shown Figures 14-15 As shown, the fourth rivet positioning fixture 113 includes a positioning plate 124, a limiting hole 125 is provided in the positioning plate 124, and a limiting groove 137 cooperating with the sealing ring 3 is provided at the top of the limiting hole 125, and the eighth driving mechanism includes a ninth cylinder 126 installed on the fourth rivet positioning fixture 113, and the sealing ring chuck 118 is installed on the cylinder rod of the ninth cylinder 126. The multiple jaws 135 of the sealing ring chuck 118 can extend into the limiting hole 125, and the jaws 135 are provided with a chamfered surface 136 for engaging the sealing ring 3.

[0088] Furthermore, the sealing ring assembly mechanism 11 includes a sealing ring temporary storage mechanism 127, and the sealing ring temporary storage mechanism 127 includes a baffle 128, a ninth driving mechanism, and a sealing ring temporary storage block 129. The baffle 128 is located above the sealing ring temporary storage block 129, and the ninth driving mechanism is used to drive the sealing ring temporary storage block 129 to reciprocate between the unloading port of the sealing ring loading mechanism 111 and the bottom of the sealing ring expansion core 117.

[0089] For example: Fig.12As shown, the ninth driving mechanism includes a tenth cylinder 130, the cylinder rod of the tenth cylinder 130 is connected to the sealing ring temporary storage block 129, and the sealing ring temporary storage block 129 is slidably matched with the frame, as shown in FIG. Fig.13 As shown, a sealing ring temporary storage groove 131 is opened on the sealing ring temporary storage block 129 toward the sealing ring feeding track 120. A soft pad such as a sponge pad or a rubber pad can be arranged in the sealing groove 103 to support the sealing ring 3, so that the soft pad can be input when the sealing ring expansion core 117 descends, so as to facilitate the removal of the sealing ring 3. A sensor corresponding to the sealing ring temporary storage groove 131 can also be arranged in the sealing ring temporary storage block 129 or the sealing ring expansion core 117 to sense that the sealing ring 3 is in place. The baffle 128 is installed on the frame in front of the sealing ring feeding track 120, and can block the sealing ring temporary storage groove 131.

[0090] The working principle of the sealing ring assembly mechanism 11 may include:

[0091] A large number of sealing rings 3 are manually poured into the vibration plate 119, and the vibration plate 119 arranges the sealing rings 3 through vibration and centrifugal action and conveys them to the sealing ring feeding track 120 in sequence. The second linear feeder 121 drives the sealing rings 3 arranged in the sealing ring feeding track 120 to be conveyed forward through vibration, and the cylinder rod of the tenth cylinder 130 extends to drive the sealing ring temporary storage groove 131 of the sealing ring temporary storage block 129 to align with the unloading port of the sealing ring feeding track 120, so that the sealing ring 3 can be directly conveyed to the sealing ring temporary storage groove 131, and the baffle 128 is used to prevent the sealing ring 3 from being unloaded too quickly and rushing out, and then the cylinder rod of the tenth cylinder 130 contracts to drive the sealing ring temporary storage block 129 to move until the sealing ring temporary storage groove 131 and the baffle 128 give way, that is, the top of the sealing ring temporary storage groove 131 is opened and moved to the bottom of the sealing ring expansion core 117.

[0092] If the loading and unloading speeds of the sealing ring 3 are slow and it is not easy for the sealing ring 3 to escape from the sealing ring temporary storage groove 131, the baffle 128 and the ninth driving mechanism can be omitted, and the sealing ring temporary storage groove 131 can be directly set below the sealing ring expansion core 117, that is, the sealing ring loading mechanism 111 directly includes the sealing ring temporary storage block 129, which simplifies the structure. Whether to configure the sealing ring temporary storage mechanism 127 can be determined according to production needs.

[0093] The seventh cylinder 115 of the sealing ring transport mechanism 112 enables the sealing ring core 117 to be located above the sealing ring 3 to be taken, and the eighth cylinder 116 drives the sealing ring core 117 to descend. The lower end of the sealing ring core 117 extends into the sealing ring 3, and the sealing ring 3 is opened and clamped on the sealing ring core 117. The eighth cylinder 116 drives the sealing ring core 117 to rise, and the sealing ring 3 can be taken out from the sealing ring temporary storage block 129. If the tenth cylinder 130 and the baffle 128 are provided, the tenth cylinder 130 is used to drive the sealing ring temporary storage block 129 to reset, so that the next sealing ring 3 is in place.

[0094] The cylinder rod of the seventh cylinder 115 extends to drive the ninth cylinder 126 and the sealing ring expansion core 117 to move above the fourth rivet positioning fixture 113, and the eighth cylinder 116 drives the sealing ring expansion core 117 to descend. Fig.14 As shown, the ninth cylinder 126 drives the sealing ring chuck 118 to rise until the jaws 135 extend out of the limiting hole 125 and are inserted into the gap between the sealing ring expansion core 117 and the sealing ring 3, and then the jaws 135 of the sealing ring chuck 118 are opened to expand the sealing ring 3 so that the sealing ring 3 is separated from the sealing ring expansion core 117. The sealing ring expansion core 117 is driven by the eighth cylinder 116 to rise and separate from the sealing ring 3, and the sealing ring expansion core 117 can be driven by the cylinder rod of the seventh cylinder 115 to retract and reset to the top of the sealing ring temporary storage groove 131.

[0095] The rivet handling mechanism 501 works in the same way. While the front rivet handling mechanism 501 is working synchronously, the corresponding rivet handling mechanism 501 can carry the rivet 1 assembled with the screw 2 in the first rivet positioning fixture 903 to the top of the limiting hole 125 of the fourth rivet positioning fixture 113 of the sealing ring assembly mechanism 11. While the rivet pressing mechanism 15 and the screw assembly mechanism 9 are working, the rivet handling mechanism 501 drives the rivet 1 to fall into the middle of the clamping claw 135 of the sealing ring chuck 118, and the sealing ring chuck 118 is driven to descend by the ninth cylinder 126. Since the limiting groove 137 of the limiting hole 125 can limit the sealing ring 3 and stop the sealing ring 3 from descending, the sealing ring 3 can be pulled down from the clamping claw 135 and put on the sealing groove 103 of the rivet 1 to realize the assembly of the sealing ring 3 and the rivet 1.

[0096] Further, such as Fig.16 As shown, the sealing ring detection mechanism 12 includes a fifth rivet positioning jig 132, a clamping mechanism and a color sensor 133. The fifth rivet positioning jig 132 can cooperate with the rivet transport mechanism 501. The clamping mechanism includes a pressure plate 138 that can be raised or lowered or moved relative to the fifth rivet positioning jig 132. The color sensor 133 is aligned above the fifth rivet positioning jig 132.

[0097] For example: the fifth rivet positioning fixture 132 is provided with a positioning hole that can cooperate with the rivet 1, the clamping mechanism includes an angle cylinder 134, the cylinder arm of the angle cylinder 134 also serves as a pressure plate 138, and the color sensor 133 is installed on the side of the angle cylinder 134. The work of the conveying mechanism is similar. While the front rivet conveying mechanism 501 is working synchronously, the corresponding rivet conveying mechanism 501 can convey the rivet 1 with the sealing ring 3 assembled in the fourth rivet positioning fixture 113 to the positioning hole of the fifth rivet positioning fixture 132. The cylinder arm of the angle cylinder 134 is rotated to the top of the rivet 1 and moves downward, which can press the rivet 1, so that the sealing ring 3 is closer to the sealing groove 103. At the same time, since the rivet 1 is metallic in color and the sealing ring 3 is black, the lower edge of the sealing ring 3 is convex after assembly. For the sealing groove 103, the color sensor 133 can be used to detect the position of the sealing ring 3 to determine whether the sealing ring 3 is missing. After that, the cylinder arm of the corner cylinder 134 rises and rotates back to its position, that is, to make way for the rivet 1. Then, the final rivet handling mechanism 501 can remove the rivet 1 from the fifth rivet positioning fixture 132. If it is detected that the sealing ring 3 is missing, the clamping can be released when moving through the sealing ring defective product rejection port 13, so that the defective rivet 1 falls into the sealing ring defective product rejection port 13. If the sealing ring 3 is not missing, the clamping is maintained when passing through the sealing ring defective product rejection port 13, and the clamping is released when it is directly moved to the unloading station 8. Since the unloading position is relatively high, a material guide plate 18 and a material receiving frame 19 can be set to receive the assembled sealing rivet product 10 to prevent the sealing rivet from being damaged.

[0098] In summary, see Figure 4 The workflow of the above-mentioned sealing rivet automatic assembly equipment may include:

[0099] S1. Manually place rivet 1, screw 2 and sealing ring 3 into corresponding silos respectively.

[0100] S2, the rivets 1 are fed sequentially by the plate pusher 14 of the rivet feeding station 6, and the third driving mechanism of the rivet pressing mechanism 15 drives the second rivet 1 to be fixed in place.

[0101] S3, the rivet transporting mechanism 501 at the front end of the transporting module 5 transports the rivet 1 from the rivet feeding track 144 to the second rivet positioning fixture 151 of the rivet pressing mechanism 15 on the adjacent processing station 7.

[0102] S4, the third driving mechanism of the rivet pressing mechanism 15 drives the second rivet 1 fixing fixture to move to the bottom of the booster 154 mechanism, and the booster 154 mechanism performs a secondary flattening process on the tail size of the rivet 1, and the third driving mechanism drives the processed rivet 1 to return to the waiting position.

[0103] S5. The next rivet transporting mechanism 501 of the transporting module 5 transports the flattened rivet 1 from the second rivet 1 fixture to the third rivet positioning fixture 163 of the rivet height detection mechanism 16, and the fourth driving mechanism drives the displacement sensor 162 to move up and down relative to the third rivet positioning fixture 163 to detect the height of the rivet 1.

[0104] S6. The next rivet transporting mechanism 501 of the transporting module 5 transports the rivet 1 in the third rivet positioning jig 163 to the first rivet positioning jig 903 of the screw assembly mechanism 9. During the process, the rivet 1 passes through the rivet height defective rejection port 17, and the rivet 1 with unqualified height is rejected and collected from the rivet height defective rejection port 17.

[0105] S7, the screw 2 is blown out through the screw feeder 905 and the separator 906, and the fifth driving mechanism of the screw locking mechanism 902 can drive the adsorption mechanism and the electric screwdriver 911 to reciprocate and move up and down between the screw feeding station 901 and the first rivet positioning fixture 903, so that the adsorption mechanism adsorbs the screw 2 and then transfers it to the top of the rivet 1, and the screw 2 is locked and tightened to assemble the screw 2 and the rivet 1.

[0106] S8, the electric screwdriver 911 determines whether the screw 2 is locked properly, and the next rivet transporting mechanism 501 of the transporting module 5 transports the rivet 1 in the first rivet positioning fixture 903 to the sealing ring assembly mechanism 11. During the process, it passes through the screw defective product rejection port 904, and the missing screws 2 or unqualified rivets 1 are removed and collected from the screw defective product rejection port 904.

[0107] S9. The sealing ring 3 is fed by the sealing ring feeding mechanism 111 of the sealing ring assembly mechanism 11, and the sealing ring expansion core 117 is driven by the seventh driving mechanism of the sealing ring conveying mechanism 112 to reciprocate and move up and down between the sealing ring feeding mechanism 111 and the fourth rivet positioning fixture 113 to convey the sealing ring 3 to the fourth rivet positioning fixture 113. The eighth driving mechanism of the sealing ring fitting structure 114 drives the jaws 135 of the sealing ring chuck 118 to move upward in the fourth rivet positioning fixture 113 and close the jaws 135 to support the sealing ring 3 to be stretched. The rivet conveying mechanism 501 places the rivet 1 assembled with the screw 2 in the sealing ring 3, and the sealing ring 3 is fitted on the rivet 1 when the sealing ring chuck 118 descends.

[0108] S10, the next rivet transporting mechanism 501 of the transporting module 5 transports the rivet 1 in the fourth rivet positioning fixture 113 to the fifth rivet positioning fixture 132 of the sealing ring detection mechanism 12, and the sealing ring 3 is further pressed by the pressing plate 138 of the clamping mechanism that is lifted or lowered or moved relative to the fifth rivet positioning fixture 132, and the color sensor 133 is aligned with the sealing ring 3 to detect whether the sealing ring 3 is present.

[0109] S11, the next rivet transporting mechanism 501 of the transporting module 5 transports the rivet 1 in the fifth rivet positioning fixture 132 to the feeding station 8. During the process, the rivet 1 without the sealing ring 3 is removed and collected from the defective screw rejecting port 904 through the defective sealing ring rejecting port 13.

[0110] S12, if the sealing ring 3 is not missing, the rivet transporting mechanism 501 transports the rivet 1 in the fifth rivet positioning fixture 132 to the unloading station 8, performs automatic unloading of good products, and obtains the sealing rivet product 10.

[0111] In the above process, multiple rivet handling mechanisms 501 can move left and right synchronously, and the rivet pressing mechanism 15, the rivet height detection mechanism 16, the screw assembly mechanism 9, the sealing ring assembly mechanism 11, and the sealing ring detection mechanism 12 can work synchronously to improve the processing rhythm. Therefore, the above-mentioned sealing rivet automatic assembly equipment can meet the functional requirements of automatic loading of each part, secondary flattening processing of the tail of the sealing rivet, automatic height detection, automatic locking of the screw 2, automatic assembly of the sealing ring 3, automatic and separate rejection of defective products, and automatic unloading of good products. The whole machine integrates the secondary flattening processing of the tail size of the rivet 1, size detection, and rejection of defective products. At the same time, it integrates the assembly and detection of the internal protection screw 2 of the rivet 1, the assembly and detection of the sealing ring 3, and the rejection of defective products. It is suitable for the continuous automatic assembly of the rivet 1, screw 2 and sealing ring 3 of the sealing rivet to improve production efficiency, turn the work of 4 people into one person's operation, eliminate the missed assembly and missed inspection of personnel during the assembly process and the resulting production defects, and the workstation layout adopts separate rejection of defective products in each process, which is convenient for subsequent manual differentiation and rework of products.

[0112] The series of detailed descriptions listed above are only specific descriptions of the feasible embodiments of the present invention, and they are not intended to limit the scope of protection of the present invention. For example, when the plane accuracy requirements of the sealing rivet are not high, the rivet pressing mechanism, the rivet height detection mechanism and the rivet height defective product rejection port can be omitted, and the sealing ring assembly mechanism can also be set on the processing station in front of the screw assembly mechanism. The design of the product silo is combined with the rhythm of automatic production. If there is no product in the silo, an alarm can be issued to prompt manual discharge. The operation of each mechanism is coordinated by the control system, and the operation can be automatically stopped in case of failure to avoid further damage. All equivalent embodiments or changes that do not deviate from the technical spirit of the present invention should be included in the scope of protection of the present invention.
