Description

Technical Field

[0001] This invention relates to the field of hardware processing, and in particular to an assembly line for folding linkages of upturned door panels. Background Technology

[0002] A tatami bed includes a bed frame and tatami mats, which are connected by the following: Figure 1 The folding linkage shown enables connection, and the folding linkage includes a connecting support and a hinge; wherein the tatami board is provided with Figure 1 The connecting support in the middle has mounting holes for rivets to facilitate connection with the hook at the end of the hinge; in addition, the inner side wall of the bed frame is rotatably connected to the end of the hinge away from the connecting support.

[0003] In actual production, connecting supports and rivets are manufactured separately, as are hinges and hooks. The existing combined processing method involves workers placing the corresponding parts at their workstations, and then using a machine to drive the rivets into the connecting supports and install the hooks into the hinges. When using existing machines, manual transfer of products is required. Therefore, the production line does not achieve seamless integration of each process, resulting in low automation and low production efficiency. Summary of the Invention

[0004] In order to overcome the defects of the existing technology, the present invention provides an assembly line for folding linkages for flip-up door panels to solve the above-mentioned problems.

[0005] The technical solution adopted by the present invention to solve its technical problem is: an assembly line for folding linkages for flip-up door panels, including a connecting support processing device and a hinge processing device;

[0006] The connecting support processing device includes a support feeding module, a support translation module and a pinning module arranged in sequence, so that the connecting support enters from the support feeding module into the support translation module, moves to the pinning module through the support translation module, and is driven into the first mounting hole of the connecting support through the pinning module.

[0007] The hinge processing device includes a crank assembly module and a material placement plate. The material placement plate is used to place the front crank. The crank assembly module includes a first feeding mechanism, a first pushing mechanism, and a pinning mechanism, so that the rear crank is fed into the first pushing mechanism through the first feeding mechanism, and moves to the material placement plate through the first pushing mechanism to connect the front crank and the rear crank. The pinning mechanism faces the material placement plate so that a second rivet is driven into the position where the front crank and the rear crank are connected.

[0008] The beneficial effects of this invention are as follows: In the assembly line for the folding linkage used in the upward-opening door panel, the first rivet is driven into the first mounting hole of the connecting support by the connecting support processing device to complete the processing of the connecting support. The front crank and the rear crank are connected by the hinge processing device, and then a second rivet is driven into the connecting position between them to complete the hinge. The assembled connecting support and the assembled hinge can then be packaged and transported separately. In use, only the connecting support needs to be installed at the front end of the hinge, and then it can be installed on the tatami bed. During the assembly of the connecting support and the hinge, there is no need for manual transfer of products, thus ensuring continuity between the various processes and improving productivity.

Detailed Implementation

[0040] The specific embodiments of the present invention will be further described below with reference to the accompanying drawings. It should be noted that these descriptions are for the purpose of aiding understanding the present invention, but do not constitute a limitation thereof. Furthermore, the technical features involved in the various embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0041] like Figure 1-30 As shown, an assembly line for a folding linkage for an upward-opening door panel includes a connecting support processing device 1 and a hinge processing device 2.

[0042] like Figure 2-5 As shown, the connecting support processing device 1 includes a support feeding module 120, a support translation module 130, and a pinning module 140 arranged in sequence, so that the connecting support enters from the support feeding module 120 into the support translation module 130, moves through the support translation module 130 to the pinning module 140, and the pinning module 140 drives the first rivet into the first mounting hole of the connecting support;

[0043] like Figure 6-30As shown, the hinge processing device 2 includes a crank assembly module 4 and a material placement plate 47. The material placement plate 47 is used to place the front crank. The crank assembly module 4 includes a first feeding mechanism 42, a first pushing mechanism 43, and a pinning mechanism 44, so that the rear crank is fed into the first pushing mechanism 43 by the first feeding mechanism 42, and moves to the material placement plate 47 by the first pushing mechanism 43 to connect the front and rear cranks. The pinning mechanism 44 faces the material placement plate 47 so that the second rivet is driven into the position where the front and rear cranks are connected. In the assembly line of the folding linkage for the flip-up door panel, the first rivet is driven into the first mounting hole of the connecting support by the connecting support processing device 1 to complete the processing of the connecting support. The front and rear cranks are connected by the hinge processing device 2, and then the second rivet is driven into the connection position between them to complete the hinge. The assembled connecting brackets and hinges can then be packaged and transported separately. In use, simply install the connecting brackets at the front end of the hinges, and then it can be installed on the tatami bed. During the assembly of the connecting brackets and hinges, no manual transfer of products is required, ensuring seamless workflow and improving productivity.

[0044] It is worth noting that the support translation module 130 includes a translation guide rail 131 and a translation pressure block 132. The output end of the support feeding module 120 faces the input end of the translation guide rail 131. The translation pressure block 132 is slidably connected to the translation guide rail 131. The translation pressure block 132 is provided with a needle U-shaped groove 1321 so that the connecting support output from the support feeding module 120 can be embedded into the needle U-shaped groove 321 of the translation pressure block 132, and the needle U-shaped groove 1321 faces the first... The mounting hole is used to move the connecting support along the translation guide rail 131 via the translation pressure block 132. The injection module 140 is located above the translation guide rail 131. The injection module 140 includes a punch 141 and a feed tube 142. The output ends of the punch 141 and the feed tube 142 are both facing the injection U-shaped groove 1321 of the translation pressure block 132, which is slid into place, so that the first rivet output from the injection module 140 passes through the injection U-shaped groove 1321 and the first mounting hole of the connecting support simultaneously. In this embodiment, "slid into place" means that the injection U-shaped groove 1321 of the translation pressure block 132 is located directly below the injection module 140. The connecting support is output to the translation guide rail 131 through the support feeding module 120. By moving the translation pressure block 132, the side of the translation pressure block 132 closest to the input end of the translation guide rail 131 (i.e., Figure 5The rear end of the translation pressure block 132 is inserted into the connecting support, aligning the U-shaped groove 1321 on the translation pressure block 132 with the first mounting hole of the connecting support. The translation of the translation pressure block 132 then moves the connecting support directly below the injection module 140, ensuring that the lower end of the punch 141 and the output end of the feed tube 142 face the injection U-shaped groove 1321. The feed tube 142 outputs the first rivet, and the punch 141 drives the first rivet in, passing it through the first mounting hole and the injection U-shaped groove 1321, thus completing the process of installing the first rivet on the connecting support. After the connecting support is processed, it can be removed from the open side of the injection U-shaped groove 1321. Throughout the entire installation process, from loading to unloading, no manual intervention is required, ensuring the continuity of the production process and improving production efficiency.

[0045] It is worth noting that, such as Figure 2 As shown, the support feeding module 120 includes a first feeding guide rail 121 and a feeding pressure block 122. The feeding pressure block 122 is disposed at the output end of the first feeding guide rail 121, and the feeding pressure block 122 moves towards or away from the output end of the first feeding guide rail 121; the output end of the first feeding guide rail 121 faces the input end of the translation guide rail 131. The first feeding guide rail 121 is used to transport the connecting support to be processed from the material cylinder to the translation guide rail 131.

[0046] It is worth noting that the support feeding module 120 also includes a feeding pressing cylinder 124. The telescopic shaft of the feeding pressing cylinder 124 faces the output end of the first feeding guide rail 121, and the telescopic shaft of the feeding pressing cylinder 124 is connected to the feeding pressing block 122. The feeding pressing cylinder 124 drives the feeding pressing block 122 to move horizontally in the left and right direction. When a connecting support is delivered to the output end of the first feeding guide rail 121, the feeding pressing block 122 moves to the left and presses the connecting support against the left inner wall of the translation guide rail 131. This ensures that after the translation pressing block 132 moves over and is inserted into the connecting support, the injection U-shaped groove 1321 of the translation pressing block 132 can be aligned with the first mounting hole of the connecting support.

[0047] Preferred, such as Figure 2 and 4As shown, a feeding limit block 123 is provided between the output end of the first feeding guide rail 121 and the input end of the translation guide rail 131. The feeding limit block 123 has a first limiting through hole 1231 to connect the output end of the first feeding guide rail 121 and the input end of the translation guide rail 131. The shape of the first limiting through hole 1231 matches the shape of the connecting support. Thus, by setting the feeding limit block 123, the posture of the connecting support when it falls to the input end of the translation guide rail 131 can be limited, thereby ensuring that after the translation pressure block 132 is translated and inserted into the connecting support, the injection U-shaped groove 1321 of the translation pressure block 132 can be aligned with the first mounting hole of the connecting support. Specifically, as shown... Figure 2 As shown, the support translation module 130 further includes a translation pressing cylinder 133 and a cylinder slide rail 134. The cylinder slide rail 134 is parallel to the translation guide rail 131. The cylinder body of the translation pressing cylinder 133 is slidably connected to the cylinder slide rail 134. The telescopic shaft of the translation pressing cylinder 133 is perpendicular to the translation guide rail 131, and the telescopic shaft of the translation pressing cylinder 133 is connected to the translation pressing block 132. The translation pressing cylinder 133 can drive the translation pressing block 132 to move in the left-right direction. The translation pressing cylinder 133 sliding on the cylinder slide rail 134 can drive the translation pressing block 132 to move in the front-back direction. After the rear end of the translation pressure block 132 is inserted into the connecting support located at the input end of the translation guide rail 131, it moves forward and moves the rear end of the translation pressure block 132 directly below the injection module 140. The injection module 140 inserts the first rivet into the connecting support. Then, the translation pressure cylinder 133 drives the translation pressure block 132 to move to the right, causing the connecting support located directly below the injection module 140 to move away from the rear end of the translation pressure block 132. This is achieved through the cooperation of the translation pressure cylinder 133 and the cylinder slide rail 134. The rear end of the translation block 132 returns to the input end of the translation guide rail 131 to retrieve a new connecting support. At this time, the front end of the translation block 132 can re-insert into the connecting support with the first rivet inserted. As the translation block 132 moves forward again, it simultaneously drives both connecting supports. The new connecting support is moved directly below the injection module 140, and the connecting support with the first rivet inserted can then be conveyed to the next workstation, such as the first rivet gun 150 and the material distribution mechanism 160. It is worth noting that, as... Figure 3As shown, the injection module 140 also includes a pneumatic base 143 and a pneumatic cylinder 144. The pneumatic base 143 is located below the translation guide rail 131, and the telescopic shaft of the pneumatic cylinder 144 faces the punch 141. The telescopic shaft of the pneumatic cylinder 144 is connected to the pneumatic base 143. In this embodiment, the translation guide rail 131 has a gap penetrating the translation guide rail 131. When the translation pressure block 132 drives the connecting support to move directly below the injection module 140, the injection U-shaped groove 1321, the first mounting hole, and the gap are connected. In this way, the pneumatic base 143 can be used to limit the first rivet driven out of the punch 141, preventing the first rivet from being inserted too far. Optionally, such as Figure 2 As shown, it also includes a first rivet gun 150, which is positioned between the output ends of the injection module 140 and the translation guide rail 131. The first rivet gun 150 rivets the first rivet in the semi-finished connecting bracket flat, thereby fixing the first rivet and preventing it from slipping out. Even after a defective connecting bracket that failed to be injected is moved from the injection module 140 to the first rivet gun 150, the first rivet gun 150 will still perform a riveting action; this is called empty riveting. Figure 2 As shown, in this embodiment, the output end of the translation guide rail 131 is provided with a material distribution mechanism 160. The finished riveted connecting support will be sent out through the material distribution mechanism 160. When the system program of the injection module 140 detects that the connecting support is successfully injected, the connecting support is a qualified product and is sent out through the straight material channel in the material distribution mechanism 160. When the system program of the injection module 140 detects that the connecting support is unsuccessfully injected, the connecting support is a defective product. The material distribution mechanism 160 will move the unloading sheet metal in advance, align the material channel in the bending direction with the outlet, and output the defective product; thereby separating the finished product from the defective product.

[0048] It is worth noting that the crank assembly module 4 also includes a base plate 41 and a top connection mechanism 45; a first feeding pipe 46 is provided on the upper part of the base plate 41, which can be connected to an external vibrating feeding device, so that the rear crank can be conveyed into the first feeding pipe 46 by the external vibrating feeding device. A first feeding mechanism 42 is provided on the side of the base plate 41 near the outlet of the first feeding pipe 46, and the outlet of the first feeding pipe 46 extends into the interior of the first feeding mechanism 42. A platform 48 is provided at the outlet of the first feeding mechanism 42, and a crank assembly storage slot 481 is opened inside the platform 48. The crank assembly storage slot 481 is connected to the discharge end of the first feeding mechanism 42. One end of the storage platform 48 is provided with the first pushing mechanism 43. A portion of the moving end of the first pushing mechanism 43 passes through the storage platform 48 and extends into the crank assembly storage slot 481. The other end of the storage platform 48 is provided with the injection mechanism 44. The lower part of the injection mechanism 44 is provided with the top contact mechanism 45. The material placement plate 47 is provided between the injection mechanism 44 and the top contact mechanism 45. The material placement plate 47 has a first storage slot 471 inside it, and the first storage slot 471 is connected to the crank assembly storage slot 481. The front crank is placed into the first storage slot 471 within the material placement plate 47, with the end of the front crank to be assembled facing the injection mechanism 44. Then, the rear crank is fed into the first feeding pipe 46 via an external vibrating feeding device. The crank can then be fed into the first feeding mechanism 42 through the first feeding pipe 46. Subsequently, the first feeding mechanism 42 is activated, pushing the rear crank into the crank assembly storage slot 481 inside the storage table 48. Once the rear crank is in the crank assembly storage slot 481, the first pushing mechanism 43 is activated, allowing the crank assembly storage slot to... The rear crank in 481 is pushed towards the first placement slot 471 in the material placement plate 47, so that the rear crank can be moved to the end of the front crank that needs to be assembled, thereby achieving accurate movement and positioning of the rear crank and avoiding positional deviation. After the rear crank is connected to the front crank, the injection mechanism 44 can be activated, so that the second rivet can be driven into the connection between the rear crank and the front crank through the injection mechanism. Subsequently, the riveting operation is performed by the external second rivet riveting equipment, thereby realizing the rapid assembly operation of the front crank and the rear crank, avoiding the use of manual placement of the second rivet for assembly operation, thereby improving the overall hinge assembly efficiency.

[0049] As attached Figure 25 , 26As shown in Figures 27, 29, and 30, the first feeding mechanism 42 includes a first mounting base 421, a first mounting plate 422, a feeding plate 423, and a top feeding module 424. The first mounting base 421 is disposed on one side of the base plate 41. The feeding plate 423 is disposed on the upper surface of the first mounting base 421, and the first mounting plate 422 is disposed on the lower surface of the feeding plate 423. A feeding groove 4231 is formed inside the feeding plate 423. The outlet of the first feeding pipe 46 extends into the feeding groove 4231. The feeding groove 4231 and the first feeding groove 424 are connected. 71 are connected. A top material module 424 is provided on the side of the feeding plate 423 away from the first pushing mechanism 43. The movable end of the top material module 424 is located in the feeding trough 4231. At the same time, the top material module 424 includes a first cylinder component 4241 and a top plate 4242. The first cylinder component 4241 is located at the end of the first mounting plate 422 away from the first pushing mechanism 43. The movable end of the first cylinder component 4241 is provided with the top plate 4242. The end of the top plate 4242 away from the first cylinder component 4241 extends into the feeding trough 4231.

[0050] When the rear crank enters the first feeding mechanism 42 from the first feeding pipe 46, it first falls into the feeding slot 4231 inside the feeding plate 423. Subsequently, by activating the first cylinder 4241 of the top material module 424, the top plate 4242 can be moved from the feeding slot 4231 towards the storage platform 48. This allows the rear crank located in the feeding slot 4231 to be pushed into the crank mounting slot 481 in the storage platform 48 through the top plate 4242, thus facilitating the operation of the first pushing mechanism 43.

[0051] As attached Figure 25 , 26 As shown in 27, 29 and 30, the first pushing mechanism 43 includes a pushing support plate 431, a second cylinder component 432 and a first pushing block 433. The pushing support plate 431 is disposed at one end of the platform 48. The second cylinder component 432 is inserted inside the pushing support plate 431. The first pushing block 433 is disposed at the movable end of the second cylinder component 432. The end of the first pushing block 433 away from the second cylinder component 432 can pass through the crank mounting storage slot 481 and extend into the first storage slot 471, so that the first pushing block 433 can pass through the platform 48 when it moves back and forth.

[0052] When the rear crank enters the crank assembly storage slot 481 inside the storage platform 48 through the first feeding mechanism 42, the second cylinder 432 can be activated to drive the first push block 433 to move inside the crank assembly storage slot 481 toward the storage platform 48. This pushes the crank inside the crank assembly storage slot 481 into the first storage slot 471 inside the material storage plate 47, thereby connecting and combining the rear crank with the front crank located in the first storage slot 471.

[0053] As attached Figure 25-30 As shown, the injection mechanism 44 includes a second mounting base 441, a first moving mechanism 442, and a pressing mechanism 443. The first mounting base 441 is disposed at the discharge end of the first pushing mechanism 43. The first moving mechanism 442 is disposed on one side of the second mounting base 441, and the pressing mechanism 443 is disposed at the moving end of the first moving mechanism 442. The pressing mechanism 443 and the top contact mechanism 45 are located on the same vertical plane. After the rear crank and the front crank are connected and combined in the first placement groove 471, the first moving mechanism 442 can be activated by starting the first moving mechanism 443. The actuating mechanism 442 drives the pressing mechanism 443 to move to the upper part of the connection between the rear crank and the front crank inside the first storage slot 471. Subsequently, the pressing mechanism 443 can be connected to the external second rivet conveying device, so that the second rivet can be driven into the connection between the rear crank and the front crank through the pressing mechanism 443. When driving the second rivet, the pressing mechanism 45 is provided to perform a top-fitting operation on the pressing mechanism 443, ensuring that the second rivet can be driven into the connection between the rear crank and the front crank normally.

[0054] Subsequently, the first moving mechanism 442 includes a second mounting plate 4421, a third cylinder component 4422, a first moving plate 4423, and a first sliding assembly 4424. The second mounting plate 4421 is disposed on one side of the second mounting base 441, and the third cylinder component 4422 is disposed on one side of the second mounting plate 4421. The first sliding assembly 4424 is disposed inside the second mounting base 441, and the sliding end of the first sliding assembly 4424 is provided with the first moving plate 4423. The upper surface is connected to the third cylinder component 4422 via the first connecting plate 49. The pressing mechanism 443 is located on the side of the first moving mechanism 442 away from the platform 48. When it is necessary to move the pressing mechanism 443, the first moving plate 4423 can be moved by the third cylinder component 4422, so that the first moving plate 4423 can be moved to the material placement plate 47 by the guide of the first sliding component 4424, so that the pressing mechanism 443 can be moved to the upper part of the connection between the rear crank and the front crank.

[0055] The pressing mechanism 443 includes a fourth cylinder 4431, a crank assembly pin 4432, and a feed block 4433. The fourth cylinder 4431 is located on the side of the second mounting base 441 away from the material placement plate 47. The crank assembly pin 4432 is located at the movable end of the fourth cylinder 4431. The feed block 4433 is located on the side of the first moving plate 4423 away from the first sliding assembly 4424. An assembly through hole 44331 is located at the center of the feed block 4433. An assembly feed hole 44332 is opened on one side of the assembly through hole 44331. The assembly feed hole 44332 can be connected to the discharge end of the external second rivet conveying device. Subsequently, the assembly through hole 44331 and the assembly feed hole 44332 are connected to allow the second rivet fed from the discharge end of the second rivet conveying device to be connected. The assembly feed hole 44332 enters the assembly through hole 44331. The end of the crank assembly pin 4432 away from the fourth cylinder component 4431 faces the assembly through hole 44331 and extends into the assembly through hole 44331. When the pressing mechanism 443 moves to the designated position, the second rivet can be fed from the assembly feed hole 44332 into the assembly through hole 44331. Then, by activating the fourth cylinder component 4431, the crank assembly pin 4432 can be moved through the fourth cylinder component 4431, so that the crank assembly pin 4432 can move along the assembly through hole 44331 to the connection between the rear crank and the front crank, thereby pushing the second rivet located in the assembly through hole 44331 to the connection between the rear crank and the front crank, so that the second rivet can be driven into the connection between the rear crank and the front crank.

[0056] Finally, the top-joining mechanism 45 includes a third mounting plate 451, a fifth cylinder component 452, and a top-joining block 453. The third mounting plate 451 is located at the bottom of the second mounting base 441. The fifth cylinder component 452 is located at the end of the third mounting plate 451 away from the material placement plate 47. The top-joining block 453 is located at the moving end of the fifth cylinder component 452. The top-joining block 453 is on the same vertical plane as the pressing mechanism 443. When the pressing mechanism 443 is working, the fifth cylinder component 452 can drive the top-joining block 453 to move upward, so that the top-joining block 453 can better support the pressing second rivet. It should be noted that when the second rivet is driven into the connection between the rear crank and the front crank, it can be further riveted by an external second rivet riveting device, thereby realizing the assembly operation of the rear crank and the front crank.

[0057] It is worth noting that the hinge processing device 2 also includes a hinge processing turntable 5 and a spring assembly module 6. The spring assembly module 6 and the crank assembly module 4 are arranged sequentially along the rotation direction of the hinge processing turntable 5. The material placement plate 47 is disposed on the hinge processing turntable 5. In this embodiment, when the hinge processing turntable 5 rotates, it drives the material placement plate 47 to rotate, thereby allowing the material placement plate 47 to pass through different workstations. The spring assembly module 6 includes a bottom base 61, a fourth mounting plate 62, a second moving mechanism 63, a loading mechanism 64, a second feeding mechanism 65, a pressing mechanism 66, and an ejection mechanism 67. A support column 68 is provided on the upper part of the bottom base 61, and the fourth mounting plate 62 is disposed on the support column 68. The fourth mounting plate 62 is far from the support column 68. A second moving mechanism 63 is provided at one end of the support column 68, and the loading mechanism 64 is provided at the movable end of the second moving mechanism 63; the movable end of the second feeding mechanism 65 is inserted into the inner cavity of the loading mechanism 64 to move the spring to the underside of the ejection mechanism 67; the movable end of the pressing mechanism 66 is inserted into the inner cavity of the loading mechanism 64 to compress the spring located directly under the ejection mechanism 67, and the upper part of the loading mechanism 64 is provided with the ejection mechanism 67; the movable end of the ejection mechanism 67 is inserted into the inner cavity of the loading mechanism 64, and the movable end of the ejection mechanism 67 faces the material placement plate 47 located on the hinge processing turntable 5, so as to drive the compressed spring into the spring mounting groove located at the front end of the front crank of the material placement plate 47. When spring assembly is required, the spring can first be fed into the loading mechanism 64 via an external spring feeding device. Once the spring is inside the loading mechanism 64, the second moving mechanism 63 can be activated to move the loading mechanism 64, the second feeding mechanism 65, the pressing mechanism 66, and the ejection mechanism 67 to the upper part near the assembly plate 69. Subsequently, the second feeding mechanism 65 is activated to send the spring to the pressing mechanism 66, where the pressing mechanism 66 compresses the spring. After compression, the ejection mechanism 67 ejects the spring from the loading mechanism 64, allowing it to enter the spring mounting slot in the front crank of the assembly plate 69, thus completing the spring assembly. Using a mechanized mechanism for spring assembly improves assembly efficiency and eliminates the need for manual clamping or pressing plates to compress the spring, significantly reducing assembly time.

[0058] It is worth noting that the hinge processing device 2 also includes a spring feeding module 7. The spring feeding module 7 includes a fifth mounting base 71, a spring feeding support plate 72, a vibrator 73, a distributor 74, and a top feeding mechanism 75. A connecting rod 713 is provided at the top of the fifth mounting base 71. The spring feeding support plate 72 is located at the end of the connecting rod 713 away from the fifth mounting base 71. A vibrator 73 is located on the upper part of the spring feeding support plate 72. A fifth mounting plate 76 is provided on the lower surface. A distributor 74 is provided on one side of the fifth mounting plate 76. A feeding slot 77 is provided on the side of the distributor 74 near the spring feeding support plate 72. A top-feeding mechanism 75 is movably installed in the feeding slot 77. The movable end of the top-feeding mechanism 75 is inserted into the spring channel in the distributor 74. The inlet 78 of the spring channel is connected to the vibrating feeder 73, and the outlet 79 of the spring channel is connected to the inner cavity of the loading mechanism 64. It should be noted that the outlet of the vibrating feeder 73 and the distributor 74 are connected through a conveying pipe. A spring is placed inside the vibrating feeder 73. The outlet of the vibrating feeder 73 is connected to the distributor 74 through a conveying pipe. When the vibrating feeder 73 is activated, the vibration generated during its operation shakes the spring inside the vibrating feeder 73 down to the conveying pipe. The spring is then fed into the inlet 78 of the distributor 74 through the conveying pipe, allowing it to enter the spring channel. The ejector mechanism 75 is then activated to block the spring from entering the spring channel inside the distributor 74, thus enabling individual spring feeding. The spring then falls from the outlet 79, avoiding continuous feeding operations by the feeding device. Individual feeding is achieved without the need for manual blocking, ensuring that the spring is transported individually to the spring mounting slot of the front crank.

[0059] It is worth noting that the feed inlet 78 is located on the top surface of the distributor 74, and the discharge outlet 79 is located on the bottom surface of the distributor 74. The feed inlet 78 and the discharge outlet 79 are connected. The vibrating feeder 73 can be connected to the feed inlet 78 on the top surface of the distributor 74 through a conveying pipe, so that the spring can enter the spring channel from the conveying pipe. An air inlet 710 is provided on the side of the distributor 74 away from the fifth mounting plate 76. The air inlet 710 is connected to the spring channel, and air is introduced through it. The inlet 710 is connected to an external jetting device, and subsequently, the inlet 710 is connected to a spring channel. This allows the gas ejected from the jetting device to enter the spring channel through the inlet 710, enabling the unobstructed springs within the top material mechanism 75 to be discharged via gas injection. A first through-hole 711 is provided on one side of the distributor 74, and a second through-hole 712 is provided above the first through-hole 711. The first through-hole 711 and the second through-hole 712 laterally penetrate the distributor 74. This allows the material blocking end of the top material mechanism 75 to enter the distributor 74 through the first through-hole 711 and the second through-hole 712, thereby blocking the springs within the distributor. (See attached diagram) Figure 7-12 As shown, the feeding mechanism 75 includes a material distribution moving plate 751, a first top-connecting component 752, and a second top-connecting component 753. The material distribution moving plate 751 is movably disposed within the feeding slot 77. One end of the material distribution moving plate 751 has a material distribution slot 7511. A connecting block 754 is disposed inside the material distribution slot 7511 to fix the connecting block 754 to the material distribution moving plate 751. A drive cylinder 755 is disposed at the end of the connecting block 754 away from the material distribution moving plate 751. The first top-connecting component 752 is disposed on the side of the material distribution moving plate 751 closest to the distributor 74, and the second top-connecting component 753 is disposed at the other end of the material distribution moving plate 751. It should be noted that the first top-connecting component 752 and the second top-connecting component 753 are not located on the same straight line. The top-connecting part of the first top-connecting component 752 faces the first through hole 711, and the top-connecting part of the second top-connecting component 753 faces the second through hole 712.

[0060] When it is necessary to block the spring inside the distributor 74, the drive cylinder 755 is activated to move the connecting block 754. As the connecting block 754 moves, it simultaneously moves the distributing moving plate 751. When the distributing moving plate 751 moves from right to left, it simultaneously moves the first top-connecting component 752 and the second top-connecting component 753 from right to left. This allows the top end of the first top-connecting component 752 to enter the spring channel inside the distributor 74 through the first through hole 711, thus blocking the spring inside the distributor 74 and preventing it from falling out of the outlet 79. Simultaneously, it allows the second top-connecting component 753 to move out of the spring channel inside the distributor 74 through the second through hole 712. This allows the spring to enter the spring channel through the feed inlet 78 normally. When the connecting block 754 is pulled back by the drive cylinder 755, the material distribution plate 751 moves from left to right, allowing the top end of the first top-connecting component 752 to move out of the spring channel inside the distributor 74 through the first through hole 711. This releases the obstruction of the spring near the discharge port 79 in the spring channel, allowing the spring to fall normally from the discharge port 79. Simultaneously, the second top-connecting component 753 moves into the spring channel inside the distributor 74 through the second through hole 712, thus blocking the spring near the feed inlet 78 in the spring channel. This prevents newly entering springs from continuously feeding.

[0061] The subsequent first top-connecting assembly 752 includes a first fixing block 7521 and a first ejector pin 7522. The first fixing block 7521 is disposed on the side of the dispensing moving plate 751 near the dispensing device 74. The first ejector pin 7522 is disposed inside the first fixing block 7521 and extends out of the outside of the first fixing block 7521. The first ejector pin 7522 faces the first through hole 711. When the first top-connecting assembly 752 moves, the first fixing block 7521 can be moved by the dispensing moving plate 751. When the first fixing block 7521 moves, the first ejector pin 7522 can be moved synchronously, so that the first ejector pin 7522 can enter or exit the spring channel inside the dispensing device 74 through the first through hole 711.

[0062] The subsequent second top-connecting assembly 753 includes a second fixing block 7531 and a second ejector pin 7532. The second fixing block 7531 is located at the end of the distributing moving plate 751 away from the connecting block 754. The second ejector pin 7532 is disposed inside the second fixing block 7531 and extends out of the second fixing block 7531, facing the second through hole 712. When the second top-connecting assembly 753 moves, the distributing moving plate 751 can drive the second fixing block 7531 to move. When the second fixing block 7531 moves, it can synchronously drive the second ejector pin 7532 to move, thereby allowing the second ejector pin 7532 to enter or exit the spring channel inside the distributor 74 through the second through hole 712.

[0063] It is worth noting that the material loading mechanism 64 includes a material loading block 641 and a cover plate 642. The material loading block 641 is disposed at the movable end of the second moving mechanism 63. A material storage groove 6411 is formed on one side of the material loading block 641. The cover plate 642 is disposed on one side of the material loading block 641 to form an inner cavity with the material storage groove 6411. The movable end of the second feeding mechanism 65 faces the material storage groove 6411. A first feed hole 6412 is formed inside the material storage groove 6411. The outlet 79 of the spring channel communicates with the inner cavity of the material loading mechanism 64 through the first feed hole 6412. A through hole 6413 is provided on one side of the first feed hole 6412. The movable end of the pressing mechanism 66 passes through the through hole 6413 and extends into the inner cavity. The material block 641 is also provided with a discharge groove 6414. The discharge groove 6414 is perpendicular to and connected to the material storage groove 6411. The through hole 6413 is located at the junction of the material storage groove 6411 and the discharge groove 6414. The discharge groove 6414 extends towards the spring mounting groove at the front end of the front crank of the material placement plate 47. The movable end of the ejection mechanism 67 passes through the discharge groove 6414 and extends into the inner cavity. The first feed hole 6412 allows connection to the discharge port of an external spring feeding device, enabling the spring to enter the material storage trough 6411 through the feed hole 6412. Once the spring is in the trough, the second feeding mechanism 65 pushes it to the through hole 6413. Then, the pressing mechanism 66, activated, allows its moving end to pass through the through hole 6413 into the material storage trough 6411, thus facilitating the loading of the material. The spring within groove 6411 is compressed until its length matches the depth of the discharge groove 6414. Then, the ejector mechanism 67 is activated, allowing its moving end to pass through the discharge groove 6414 into the loading block 641. The loading slot 6411 is perpendicularly connected to the discharge groove 6414. The moving end of the ejector mechanism 67 continues to move, pushing the spring from the discharge groove 6414 into the spring mounting slot in the front crank of the mounting plate 69, thus enabling spring loading. It should be noted that the depth of the discharge groove 6414 is less than the depth of the loading slot 6411.

[0064] As attached Figure 13-15As shown, the second moving mechanism 63 includes a spring assembly drive 631, a slider guide rail assembly 632, and a second moving plate 633. The spring assembly drive 631 is located at the end of the fourth mounting plate 62 away from the support column 68. The slider guide rail assembly 632 is located at the lower part of the spring assembly drive 631. The sliding end of the slider guide rail assembly 632 is provided with the second moving plate 633. The bottom surface of the second moving plate 633 is connected to the loading mechanism 64. The end of the second moving plate 633 facing the spring assembly drive 631 has a slot 6331. The moving end of the spring assembly drive 631 has a locking block 634, which is engaged in the slot 6331.

[0065] Subsequently, when it is necessary to move the loading mechanism 64, the second feeding mechanism 65, the pressing mechanism 66, and the ejection mechanism 67 to the upper part near the mounting plate 69: the spring assembly drive 631 can be activated first, and the second moving plate 633 can be moved by the spring assembly drive 631, so that the second moving plate 633 can move downward along the slider guide rail assembly 632. When the second moving plate 633 moves, the loading mechanism 64 can be moved simultaneously. After the loading mechanism 64 moves, the second feeding mechanism 65, the pressing mechanism 66, and the ejection mechanism 67 can be moved downward simultaneously.

[0066] As attached Figure 13-19 As shown, the material loading mechanism 64 includes a material loading block 641 and a cover plate 642. The material loading block 641 is located at the moving end of the second moving mechanism 63. The cover plate 642 is located on one side of the material loading block 641. A material loading groove 6411 is formed on one side of the material loading block 641. The moving end of the second feeding mechanism 65 faces the material loading groove 6411. A first feeding hole 6412 is formed inside the material loading groove 6411. A through hole 6413 is formed on one side of the first feeding hole 6412. The moving end of the pressing mechanism 66 faces the through hole 6413. A discharge groove 6414 is also formed on the side of the material loading block 641 near the material loading groove 6411. The material loading groove 6411 and the discharge groove 6414 are vertically connected. The moving end of the ejection mechanism 67 faces the discharge groove 6414. Figure 13-18As shown, the second feeding mechanism 65 includes a first support plate 651, a feeding drive component 652, and a second pusher block 653. The first support plate 651 is disposed on one side of the second moving plate 633. The feeding drive component 652 is disposed at the end of the first support plate 651 away from the second moving plate 633. The second pusher block 653 is disposed at the moving end of the feeding drive component 652. The second pusher block 653 faces the material storage groove 6411 of the material block 641. At the same time, a second feeding hole 6531 is opened on the side of the second pusher block 653 away from the feeding drive component 652. The second feeding hole 6531 faces the first feeding hole 6412. A feeding slot 6532 is opened at the end of the second pusher block 653 away from the feeding drive component 652. The feeding slot 6532 is connected to the second feeding hole 6531.

[0067] The outlet of the external spring feeding device is connected to the first feed hole 6412. When it is necessary to move the spring from the first feed hole 6412 to the through hole 6413, the spring can enter the second feed hole 6531 from the first feed hole 6412, so that the spring can enter the second push block 653. The feeding drive 652 pushes the second push block 653 to move in the material storage groove 6411, so that the spring can be moved from the second feed hole 6531 to the through hole 6413, so that it can communicate with the through hole 6413, so that the subsequent pressing mechanism 66 can compress the spring located in the second push block 653.

[0068] As attached Figure 13-19As shown, the subsequent pressing mechanism 66 includes a second support plate 661, a pressing drive 662, a top block 663, and a spring-mounted ejector pin 664. The second support plate 661 is located on the side of the second moving plate 633 away from the second feeding mechanism 65. The pressing drive 662 is located on one side of the second support plate 661. The top block 663 is located through the second support plate 661 at the output end of the pressing drive 662. The spring-mounted ejector pin 664 is located on the side of the top block 663 away from the pressing drive 662. The moving end of the spring-mounted ejector pin 664 faces the through hole 6413. When the second push block 653 moves to the through hole 6413, the pressing drive 662 can be activated, and the pressing drive 662 can be used to press the material. The movement of component 2 drives the top block 663 to move towards the material block 641, which in turn drives the spring assembly pin 664 to move, allowing the spring assembly pin 664 to enter the material block 641 through the through hole 6413. Subsequently, the spring assembly pin 664 is moved to enter the second feed hole 6531, thereby compressing the spring in the second feed hole 6531. When the spring length is compressed to match the depth of the discharge groove 6414, the operation of the pressing drive component 662 is stopped. Then, the ejection mechanism 67 moves the spring from the second push block 653 into the bottom of the discharge groove 6414 of the material block 641, thus performing the discharge operation.

[0069] The subsequent ejection mechanism 67 includes a third support plate 671, an ejection drive 672, and an ejection push rod 673. The third support plate 671 is located above the second moving plate 633. The ejection drive 672 is located on the upper surface of the third support plate 671. The output end of the ejection drive 672 passes through the third support plate 671 and is provided with an ejection push rod 673. The moving end of the ejection push rod 673 faces the discharge chute 6414.

[0070] After the spring is compressed by the pressing mechanism 66, the ejector drive 672 is activated, which drives the ejector push rod 673 to move downward, allowing the ejector push rod 673 to enter the material block 641 through the discharge groove 6414. Subsequently, the ejector drive 672 continues to drive the ejector push rod 673 to move downward, allowing the ejector push rod 673 to enter the feeding slot 6532 of the second push block 653. In this way, the ejector push rod 673 pushes the spring into the bottom of the discharge groove 6414 through the feeding slot 6532. Then, by controlling the ejector push rod 673 to move downward, the spring can be pushed from the discharge groove 6414 into the spring mounting slot in the front crank of the mounting plate 69, thus realizing the spring assembly operation.

[0071] It is worth noting that the hinge processing device 2 also includes a slider assembly module 8, which is located after the spring assembly module 6 along the rotation direction of the hinge processing turntable 5. The slider assembly module 8 includes a support base 81, a feeding mechanism 82, a moving clamping mechanism 83, and a second pushing mechanism 85. Both the second pushing mechanism 85 and the moving clamping mechanism 83 are located on the support base 81. The output end of the second pushing mechanism 85 faces the front end of the front crank located on the material placement plate 47. A feeding plate 8 is provided between the material placement plate 47 and the second pushing mechanism 85. 6. The second pushing mechanism 85 pushes the slider located on the feeding plate 86 into the front end of the front crank. The support base 81 is provided with a movable clamping mechanism 83, which includes a moving unit 831 and a clamping unit 832. The moving unit 831 slides relative to the support base 81 and is connected to the clamping unit 832. The movable clamping mechanism 83 is located above the material placement plate 47, so that the clamping unit 832 clamps the slider located on the feeding mechanism 82 and the moving unit 831 moves the slider to the feeding plate 86. The upper surface of the feeding plate 86 is provided with a third storage groove 861, which is connected to the first storage groove 471. When assembling the slider is required, first place the front crank into the first storage slot 471 of the material placement plate 47, with the end of the front crank to be assembled facing the inlet of the first storage slot 471. Then, by connecting the external vibrating unloading device to the loading mechanism 82, the slider from the external unloading device can be sent to the loading mechanism 82. The loading mechanism 82 then performs the loading operation on the slider. Next, the moving unit 831 within the moving clamping mechanism 83 is activated, allowing the clamping unit 832 to be moved to the loading mechanism 82. When it reaches the designated position, the clamping unit 832 is activated. The clamping unit 832 is used to clamp the slider in the feeding mechanism 82. Then, the moving unit 831 moves the clamping unit 832 to the inlet of the first placement slot 471 of the material placement plate 47. Subsequently, the clamping operation of the clamping unit 832 is released so that the slider clamped by the clamping unit 832 can be placed on the discharge plate 86. Then, by activating the second pushing mechanism 85, the slider on the discharge plate 86 can be pushed into one end of the front crank at the first placement slot 471. This allows the slider to be accurately assembled into one end of the front crank. At the same time, the use of a mechanized mechanism can improve the slider assembly efficiency.

[0072] As attached Figure 20-23As shown, the feeding mechanism 82 includes a sixth mounting base 821, a second placement plate 822, a second feeding pipe 823, and a first driving member 824. The sixth mounting base 821 is disposed on one side of the support base 81. The second placement plate 822 is disposed on the upper part of the sixth mounting base 821. A second placement groove 8221 is disposed on the upper part of the second placement plate 822. A third push block 825 is disposed in the second placement groove 8221. A second connecting plate 826 is disposed on one side of the second placement plate 822. A second feeding pipe 823 is disposed on one side of the second connecting plate 826. The outlet of the second feeding pipe 823 faces the first placement groove 471. The first driving member 824 is disposed at the end of the second placement plate 822 away from the support base 81. The movable end of the first driving member 824 is connected to the third push block 825 so that the third push block 825 can move in the second placement groove 8221 through the operation of the first driving member 824.

[0073] When the feeding mechanism 82 is connected to an external vibrating unloading device, the slider is fed into the second storage slot 8221 above the second storage plate 822 via the second feeding pipe 823. Subsequently, by activating the first driving member 824, the moving end of the first driving member 824 pushes the third push block 825 to move, allowing the third push block 825 to continue moving within the second storage slot 8221. This pushes the slider within the second storage slot 8221 towards the end close to the moving clamping mechanism 83, enabling the moving clamping mechanism 83 to clamp the slider. It should be noted that the third push block 825 has an L-shaped structure, with its vertical end connected to the first driving member 824 and its horizontal end placed within the second storage slot 8221.

[0074] As attached Figure 20-24As shown, the moving unit 831 includes a sixth mounting plate 8311, a second sliding assembly 8312, a slider assembly moving plate 8313, and a second driving member 8314. The sixth mounting plate 8311 is located at the top of the support base 81 near the feeding mechanism 82. The second sliding assembly 8312 is located on the side of the sixth mounting plate 8311 away from the support base 81. The slider assembly moving plate 8313 is located on the side of the second sliding assembly 8312 away from the sixth mounting plate 8311. A clamping unit 832 is located on the side of the slider assembly moving plate 8313 away from the second sliding assembly 8312. First baffles 83 are located on both sides of the sixth mounting plate 8311. 15 and second baffle 8316, a second driving member 8314 is provided on one side of the first baffle 8315, the movable end of the second driving member 8314 passes through the first baffle 8315 and is connected to the slider assembly moving plate 8313, and a limiter 8317 is provided inside the second baffle 8316; the gripping unit 832 includes a third driving member 8321, a seventh mounting plate 8322 and a gripper 8323, the third driving member 8321 is provided on the side of the slider assembly moving plate 8313 near the feeding mechanism 82, the movable end of the third driving member 8321 is provided with the seventh mounting plate 8322, and the lower surface of the seventh mounting plate 8322 is provided with the gripper 8323.

[0075] When the third pusher 825 is positioned near the end of the second storage slot 8221 close to the movable clamping mechanism 83: the second drive member 8314 can be activated, causing the slider assembly moving plate 8313 to move in conjunction with the second sliding assembly 8312. This allows the second drive member 8314 to push the slider assembly moving plate 8313 towards the feeding mechanism 82. As the slider assembly moving plate 8313 continues to move, the clamping unit 832 moves synchronously, allowing it to move to the second storage plate 822 of the feeding mechanism 82. Subsequently, when the clamping unit 832 moves to the upper part of the second storage slot 8221 of the second storage plate 822: the third drive member 8321 can be activated, causing the seventh mounting plate 8322 to move towards the second storage slot 8221. As the seventh mounting plate 8322 moves, the clamping jaws 8323 move synchronously. When the seventh mounting plate 8322 moves a certain distance, the clamping jaws 8323 are activated. The device can grip the slider located in the second storage slot 8221. After gripping, the seventh mounting plate 8322 and the gripper 8323 are retrieved by the third drive unit 8321, thus achieving the gripping operation of the slider. Then, when it is necessary to send the slider to the third storage slot 861 in the feeding plate 86: the second drive unit 8314 in the moving unit 831 can be activated, which drives the slider assembly moving plate 8313 to move towards the feeding plate 86, thereby synchronously driving the gripping unit 832 to move towards the feeding plate 86. When the gripping unit 832 moves to the upper part of the feeding plate 86, the third drive unit 8321 can be activated to make the gripper 8323 move towards the third storage slot 861. After moving to a specified distance, the gripper 8323 is activated to release the gripping operation of the slider, allowing the slider to fall into the third storage slot 861.

[0076] As attached Figure 20-24 As shown, the second pushing mechanism 85 includes a fourth driving member 851, an L-shaped push rod 852, and a second limiting block 853. The fourth driving member 851 is located at the inlet of the first storage slot 471 of the material placement plate 47. The moving end of the fourth driving member 851 is provided with an L-shaped push rod 852 so that the L-shaped push rod 852 can move through the fourth driving member 851. The second limiting block 853 is located at the inlet of the first storage slot 471. The moving end of the L-shaped push rod 852 passes through the second limiting block 853 and enters the first storage slot 471.

[0077] The second limiting block 853 has a second limiting through hole 8531 inside. The diameter of the second limiting through hole 8531 is the same as the diameter of the first storage groove 471. The second limiting through hole 8531 and the first storage groove 471 are on the same straight line so that the moving end of the L-shaped push rod 852 can pass through the second limiting through hole 8531 and then enter the first storage groove 471.

[0078] When the slider is inside the third storage slot 861, the fourth drive member 851 of the second pusher mechanism 85 is activated. The fourth drive member 851 drives the L-shaped push rod 852 to move towards the second limiting through hole 8531 of the second limiting block 853. After the L-shaped push rod 852 passes through the second limiting through hole 8531, it can enter the third storage slot 861. The fourth drive member 851 continuously drives the L-shaped push rod 852 to move further, which can push the slider in the third storage slot 861 towards the first storage slot 471. This pushes the slider into one end of the front crank in the first storage slot 471, thereby realizing the assembly operation of the slider.

[0079] In this embodiment, the lower locking component is first placed on the material placement plate 47. In subsequent steps, the spring is first installed into the spring mounting slot at the front end of the front crank, and then the slider is installed. Finally, the upper locking component is moved to the front end of the front crank located on the material placement plate 47 through the corresponding upper locking component installation station, so that the upper locking component and the lower locking component are engaged, thereby restricting the slider and the spring, thus completing the assembly of the front crank.
