[0191] Reference Figures 1 to 23This invention provides an assembly device for an automotive electric tailgate strut damper assembly. The assembly device includes a divider turntable 1, a damper housing feeding assembly 2, a first set of fixed shim feeding assembly 3A, a first set of carbon fiber friction plate feeding assembly 4A, a metal sheet feeding assembly 5, a second set of carbon fiber friction plate feeding assembly 4B, a second set of fixed shim feeding assembly 3B, a spring feeding assembly 6, a bottom cover feeding assembly 7, and a discharge assembly 8.

[0192] Reference Figure 1 The divider turntable 1 has several product positioning fixtures 9 arranged circumferentially on its turntable. Along the outer circumferential direction of the divider turntable 1, there are a damper housing manual feeding station, a damper housing feeding station, a first fixed gasket feeding station, a first carbon fiber friction plate feeding station, a metal sheet feeding station, a second carbon fiber friction plate feeding station, a second fixed gasket feeding station, a spring feeding station, a bottom cover feeding station, and a discharge station.

[0193] The product positioning fixture 9 is preferably detachably mounted on the turntable. The product positioning fixture 9 typically only accommodates one type of damper; however, as shown in Figure 3(a), the product positioning fixture 9 can be used to install dampers of various specifications. Figures 3(b) to 3(d) The damper 10 is shown. Therefore, considering that the assembly equipment can produce dampers of different shapes to improve the utilization rate of the equipment, the present invention adapts the product positioning fixture 9 to accommodate dampers of different shapes.

[0194] In addition, for dampers of different shapes, the present invention adds a manual feeding station for damper housings, and no components are set at the manual feeding station for damper housings, so that the present invention can place damper housings of different shapes on the corresponding product positioning fixture 9 inside the manual feeding station for damper housings by manual placement.

[0195] The damper housing feeding assembly 2 is located at the damper housing feeding station. The damper housing feeding assembly 2 is used to feed the damper housing in the damper housing vibrating material tray 21 to the product positioning fixture 9 inside the damper housing feeding station.

[0196] The first set of fixed shim feeding components 3A is located at the first fixed shim feeding station, and the second set of fixed shim feeding components 3B is located at the second fixed shim feeding station. The first set of fixed shim feeding components 3A is used to feed the fixed shims in the fixed shim cylinder at the first fixed shim feeding station to the damper housing on the product positioning fixture 9 inside the first fixed shim feeding station. The second set of fixed shim feeding components 3B is used to feed the fixed shims in the fixed shim cylinder at the second fixed shim feeding station to the damper housing on the product positioning fixture 9 inside the second fixed shim feeding station.

[0197] The first set of carbon fiber friction plate feeding assembly 4A is located at the first carbon fiber friction plate feeding station, and the second set of carbon fiber friction plate feeding assembly 4B is located at the second carbon fiber friction plate feeding station. The first set of carbon fiber friction plate feeding assembly 4A is used to feed the carbon fiber friction plates in the carbon fiber friction plate cylinder at the first carbon fiber friction plate feeding station to the damper housing on the product positioning fixture 9 inside the first carbon fiber friction plate feeding station. The second set of carbon fiber friction plate feeding assembly 4B is used to feed the carbon fiber friction plates in the carbon fiber friction plate cylinder at the second carbon fiber friction plate feeding station to the damper housing on the product positioning fixture 9 inside the second carbon fiber friction plate feeding station.

[0198] The metal sheet feeding assembly 5 is located at the metal sheet feeding station. The metal sheet feeding assembly 5 is used to feed the metal sheet in the metal sheet cylinder 51 to the damper housing on the product positioning fixture 9 inside the metal sheet feeding station.

[0199] The spring feeding assembly 6 is located at the spring feeding station. The spring feeding assembly 6 is used to feed the spring in the spring vibrating material tray 61 to the damper housing on the product positioning fixture 9 inside the spring feeding station.

[0200] The bottom cover feeding assembly 7 is located at the bottom cover feeding station. The bottom cover feeding assembly 7 is used to feed the bottom cover in the bottom cover vibrating material tray 71 to the damper housing on the product positioning fixture 9 inside the bottom cover feeding station.

[0201] The unloading assembly 8 is located at the unloading station and is used to unload the bottom cover assembled on the product positioning fixture 9.

[0202] The damper housing feeding assembly 2, the first set of fixed gasket feeding assembly 3A, the first set of carbon fiber friction plate feeding assembly 4A, the metal plate feeding assembly 5, the second set of carbon fiber friction plate feeding assembly 4B, the second set of fixed gasket feeding assembly 3B, the spring feeding assembly 6, the bottom cover feeding assembly 7, and the unloading assembly 8 of the present invention are arranged sequentially around the outer circumference of the divider turntable 1. This allows the damper housing to be placed in the product positioning fixture 9 by the damper housing feeding assembly 2. Under the rotation of the divider turntable 1, a fixed gasket, a carbon fiber friction plate, a metal plate, another carbon fiber friction plate, another fixed gasket, a spring, and a bottom cover are sequentially placed into the damper housing of the product positioning fixture 9, forming a semi-finished product. The semi-finished product is then assembled into a finished product, i.e., a damper, by screwing the bottom cover on. The unloading assembly 8 then unloads the product.

[0203] Therefore, as Figures 3(b) to 3(d)The damper 10 shown includes a damper housing 101, and a first fixing pad 102, a first carbon fiber friction pad 103, a metal plate 104, a second carbon fiber friction pad 105, a second fixing pad 106, a spring 107, and a bottom cover 108 rotatably connected to the damper housing 101, arranged from bottom to top within the damper housing 101.

[0204] In some embodiments, except for the damper housing vibrating feeder 21, the spring vibrating feeder 61 and the bottom cover vibrating feeder 71, the divider turntable 1 and its surrounding components are all arranged on the worktable, and each vibrating feeder is arranged on the side of the worktable.

[0205] In some embodiments, refer to Figure 2 The divider turntable 1 is also provided with a fixed plate 12 that is fixed relative to the turntable 11. The fixed plate 12 is located inside several product positioning fixtures 9. Three fixed plate laser sensors 13 are respectively set along the circumference of the fixed plate 12 to detect whether there are products on the product positioning fixtures 9. The three fixed plate laser sensors 13 are respectively set on the opposite side of the housing manual feeding station, the damper housing feeding station, and the unloading station, and are respectively facing the product positioning fixtures 9 inside each station.

[0206] Only when a damper housing is present on the product positioning fixture 9 inside the manual feeding station or the damper housing feeding station will the turntable 11 be driven to rotate, thereby driving the product positioning fixture 9 to rotate to the subsequent stations for feeding processes. Only when a semi-finished product is present on the product positioning fixture 9 inside the unloading station will the unloading assembly 8 be driven to perform the capping and unloading processes for the bottom cover.

[0207] In some embodiments, referring to FIG3(a), the product positioning fixture 9 includes a base plate 91, a positioning fixing seat 92, and a positioning shaft 93.

[0208] The base plate 91 is fixed on the turntable 11. Preferably, the base plate 91 is detachably fixed on the turntable 11 so that the corresponding product positioning fixture 9 can be replaced according to the different shapes of the dampers.

[0209] The positioning and fixing seat 92 is fixed on the base plate 91. The top surface of the positioning and fixing seat 92 is provided with a positioning receiving cavity 921. One or more fixing seat positioning grooves 922 are provided in the positioning receiving cavity 921. A positioning shaft 93 is provided in the positioning receiving cavity 921. One or more positioning protrusions 931 protrude outward from the circumferential surface of the positioning shaft 93.

[0210] In this embodiment, the positioning cavity 921 is used to accommodate the damper housing. Typically, the damper housing has a protrusion at its bottom end. Therefore, a fixing seat positioning groove 922 is provided to engage with the protrusion at the bottom end of the damper housing, thereby confining the damper housing within the positioning cavity 921 to prevent rotation. The metal sheet is typically a ring-shaped structure, with one or more inner grooves on the inner wall of the inner ring. After the metal sheet is placed into the damper housing, a positioning shaft 93 passes through the inner groove to position the metal sheet and prevent rotation.

[0211] When the shape of the damper housing is different, the number, shape, and position of the fixing seat positioning groove 922 on the positioning receiving cavity 921 are also different. When the shape of the metal sheet is different, the specifications of the positioning shaft 93 and the number, shape, and position of the positioning protrusion 931 on its outer side are also different.

[0212] In some embodiments, refer to Figure 1 , reference Figures 4 to 6 The damper housing feeding assembly 2 includes a damper housing vibrating feeder 21, a damper housing dispensing device 22, and a damper housing automatic assembly device 23. The damper housing dispensing device 22 includes a housing receiving groove 221, which is used to receive damper housings fed from the damper housing vibrating feeder 21. The damper housing automatic assembly device 23 includes a housing assembly gripper 231 capable of horizontal and vertical movement. The housing assembly gripper 231 clamps the damper housings in the housing receiving groove 221 and sends them to the product positioning fixture 9 inside the damper housing feeding station.

[0213] In some embodiments, refer to Figure 5 The damper housing distribution device 22 also includes a housing distribution slide cylinder 222, a housing distribution fixing seat 223, a housing distribution connecting frame 224, a housing distribution stop block 225, and a housing distribution laser sensor 226.

[0214] The housing distribution slide cylinder 222 can be installed at the damper housing feeding station via the distribution base plate.

[0215] The housing distribution fixing seat 223 is connected to the horizontal movement end of the housing distribution slide cylinder 222 via the housing distribution connecting frame 224. The housing distribution slide cylinder 222 drives the housing distribution fixing seat 223 to move horizontally. The housing distribution fixing seat 223 is provided with a housing receiving groove 221. The housing receiving groove 221 is provided with at least one housing positioning groove 2211. The housing receiving groove 221 has a housing receiving groove opening on the side facing the damper housing vibrating material plate 21. The housing receiving groove opening is connected to the damper housing vibrating material plate 211 via the housing distribution direct vibration 211. The length direction of the housing positioning groove 2211 is parallel to the length direction of the housing distribution direct vibration 211. Usually, the bottom end of the damper housing has one or more protrusions, so that when the damper housing is sent into the housing receiving groove 221, the protrusions at its bottom end are exactly located in the housing positioning groove 2211, thereby achieving the positioning of the damper housing.

[0216] The shell material distribution block 225 is located on the side of the shell material distribution fixing seat 223, which is located on the side of the shell receiving groove opening. In specific implementation, the shell material distribution block 225 can be fixed to the worktable by the shell material distribution baffle, so that the shell material distribution block 225 is fixed relative to the shell material distribution fixing seat 223.

[0217] The housing distribution laser sensor 226 is used to detect whether a damper housing is being received on the housing receiving groove 221. The housing distribution laser sensor 226 is mounted on the housing distribution fixing base 223 and faces upwards towards the housing receiving groove 221. Of course, other sensors that detect the presence of a damper housing can also be used instead.

[0218] When the housing distribution laser sensor 226 detects that a damper housing is supported on the housing receiving groove 221, it drives the housing distribution slide cylinder 222 to move. The housing distribution slide cylinder 222 drives the housing distribution fixing seat 223 to move horizontally towards the side close to the housing distribution block 225. The housing distribution block 225 blocks the opening of the housing receiving groove, and the side of the housing distribution fixing seat 223 facing the damper housing vibrating material plate 21 blocks the outlet of the housing distribution direct vibration 211.

[0219] When the housing distribution laser sensor 226 detects that the damper housing on the housing receiving groove 221 has been removed by the damper housing automatic assembly device 23, it drives the housing distribution slide cylinder 222 to move. The housing distribution slide cylinder 222 drives the housing distribution fixing seat 223 to move horizontally away from the housing distribution stop block 225. Then, the opening of the housing receiving groove connects to the housing distribution direct vibration 211 to receive the next damper housing.

[0220] In some embodiments, refer to Figure 5The damper housing feeding assembly 2 also includes a damper housing detection assembly for detecting the angle of the damper housing. The damper housing detection assembly includes a housing detection lighting lamp 241, a housing detection camera, and a housing detection module.

[0221] A housing inspection light 241 is positioned below the housing receiving groove 221 to illuminate the damper housing held on the housing receiving groove 221. A housing inspection camera is positioned above the housing receiving groove 221 to acquire images of the damper housing on the housing receiving groove 221. A housing inspection module is connected to the housing inspection camera and receives the damper housing images. The housing inspection module compares the damper housing images with preset housing standard images and determines the rotation angle based on the angular difference between the damper housing images and the housing standard images. The housing assembly gripper 231 can perform horizontal, vertical, and rotational movements around the vertical direction. By driving the housing assembly gripper 231 to rotate by a certain angle, the damper housing is placed on the product positioning fixture 9 at a preset angle.

[0222] In addition to a protrusion at the bottom, the damper housing also has one or more protrusions at the top and inside. Among these, a set of protrusions at the top and inside are vertically aligned. This embodiment utilizes this alignment to adjust the angle of the damper housing placed on the product positioning fixture 9. Since a housing positioning groove 2211 is provided within the housing receiving groove 221, the angle difference between the damper housing image in the housing receiving groove 221 and the standard housing image is 0°, 90°, 180°, or 270°. When the housing detection module compares the two images, it can determine the angle difference as long as the two images are identical. The required rotation angle can be determined by rotating the damper housing image a maximum of three times.

[0223] In some embodiments, refer to Figure 6 The damper housing automatic assembly device 23 also includes a housing assembly slide electric cylinder 232, a housing assembly slide air cylinder 233, a housing assembly rotary electric cylinder 234, and a housing assembly gripper air cylinder 235.

[0224] The housing assembly slide electric cylinder 232 can be installed at the damper housing feeding station via an assembly bracket.

[0225] The housing assembly slide cylinder 233 is directly mounted or mounted on the horizontal movement end of the housing assembly slide electric cylinder 232 via a connecting plate, and the housing assembly slide electric cylinder 232 drives the housing assembly slide cylinder 233 to move horizontally.

[0226] The housing assembly rotary electric cylinder 234 is directly mounted or mounted on the lifting end of the housing assembly slide cylinder 233 via another connecting plate, and the housing assembly slide cylinder 233 drives the housing assembly rotary electric cylinder 234 to perform lifting and lowering movements.

[0227] The housing assembly gripper cylinder 235 is directly mounted or mounted on the rotating end of the housing assembly rotary electric cylinder 234 via a connecting flange and a fixed seat. The housing assembly rotary electric cylinder 234 drives the housing assembly gripper cylinder 235 to rotate around the lifting direction.

[0228] The housing assembly gripper 231 is mounted on the gripper end of the housing assembly gripper cylinder 235, and the housing assembly gripper cylinder 235 drives the housing assembly gripper 231 to clamp or release the damper housing.

[0229] In some embodiments, refer to Figure 1 , Figures 7 to 9 Both the first set of fixed gasket feeding components 3A and the second set of fixed gasket feeding components 3B include a fixed gasket cylinder 31, a fixed gasket dispensing device 32, and a fixed gasket automatic assembly device 33. The fixed gasket dispensing device 32 includes a liftable gasket dispensing pusher block 321, which is located below the fixed gasket cylinder 31 and can move the fixed gaskets upward along the fixed gasket cylinder 31. The fixed gasket automatic assembly device 33 includes a gasket assembly vacuum suction head 331 that can perform horizontal and vertical movements. The gasket assembly vacuum suction head 331 picks up the fixed gasket at the top of the fixed gasket cylinder 31 and sends it to the damper housing on the product positioning fixture 9 inside the first or second fixed gasket feeding station.

[0230] In some embodiments, refer to Figure 8 The fixed gasket distribution device 32 also includes a gasket distribution fixing seat 322, a gasket distribution guide shaft 323, a gasket distribution linear electric cylinder 324, and a gasket distribution floating joint 325.

A gasket distribution pusher block 321 is provided inside the gasket distribution communication port. When the gasket distribution pusher block 321 moves upward, the top of the gasket distribution pusher block 321 extends into the fixed gasket cylinder 31 and moves the fixed gasket upward.

[0232] The top end of the gasket distribution guide shaft 323 is connected to the bottom end of the gasket distribution push block 321.

[0233] The lifting motion end of the gasket dispensing linear electric cylinder 324 is connected to the bottom end of the gasket dispensing guide shaft 323 through the gasket dispensing floating joint 325. The gasket dispensing linear electric cylinder 324 drives the gasket dispensing guide shaft 323 and the gasket dispensing pusher block 321 to perform lifting motion.

[0234] In some embodiments, refer to Figure 8The gasket distribution guide shaft 323 is connected to the gasket distribution fixed seat 322 via the gasket distribution linear bearing 326.

[0235] In some embodiments, refer to Figure 8 The gasket dispensing linear electric cylinder 324 is connected to the gasket dispensing fixing seat 322 via the gasket dispensing connecting frame 327.

[0236] In some embodiments, refer to Figure 8 The fixed gasket dispensing device 32 also includes a gasket dispensing proximity sensor 328, which is used to detect whether there is a fixed gasket cylinder 31 above the gasket dispensing connection port. The gasket dispensing proximity sensor 328 is set on the gasket dispensing fixed seat 322 and faces the gasket dispensing connection port.

[0237] Only after the presence of a fixed gasket cylinder 31 above the gasket dispensing connection port is detected can the gasket dispensing pusher block 321 be driven to move up and down. Of course, other sensors that detect the presence of the fixed gasket cylinder 31 can also be used instead.

[0238] In some embodiments, refer to Figure 8 The fixed gasket distribution device 32 also includes two gasket distribution slide blocks 329. Each of the two gasket distribution slide blocks 329 is provided with a gasket distribution slide 2391.

Positioning ribs, positioning grooves, or other positioning components can be provided inside the fixing pad cylinder 312 according to the shape of the fixing pads to achieve positioning of the placed positioning pads, but without affecting the upward movement of the fixing pads within the fixing pad cylinder 312. The positioning ribs, positioning grooves, or other positioning components can also provide guidance during the upward movement of the fixing pads.

[0241] A viewing window can also be provided on the fixed gasket cylinder 312 along the lifting direction to observe whether there is a fixed gasket inside the fixed gasket cylinder 312 and whether the fixed gasket cylinder 31 needs to be replaced. When it is necessary to replace the fixed gasket cylinder 31, simply slide the fixed gasket cylinder 31 out of the two gasket distribution grooves.

[0242] In some embodiments, refer to Figure 8 The gasket distribution slide block 329 is provided with one or more gasket distribution locking parts 3111 for locking the gasket cylinder mounting plate 311.

[0243] In specific implementation, the gasket distribution locking component 3111 can be connected to the gasket distribution slide block 329 by a locking bolt threaded through the gasket distribution slide block 329 and then abutting against the gasket cylinder mounting plate 311. Alternatively, a locking hole can be provided on the gasket cylinder mounting plate 311, and the gasket distribution locking component 3111 can be connected to the gasket distribution slide block 329 by a locking bolt threaded through the gasket distribution slide block 329 and then inserted into the locking hole to achieve locking.

[0244] In some embodiments, refer to Figure 9 The first set of fixed gasket feeding assembly 3A's fixed gasket automatic assembly device 33 also includes a gasket assembly and oiling device for quantitatively injecting oil into the fixed gaskets that have been installed in the damper housing. The gasket assembly and oiling device includes a gasket assembly and oiling head 332 that can perform horizontal and vertical movements. The gasket assembly and oiling head 332 is connected to an external oil supply device through a gasket assembly and oiling valve 333, and quantitative lubricating oil is injected into the fixed gaskets that have been installed in the damper housing through the gasket assembly and oiling head 332.

[0245] Since the second set of fixed gasket feeding assembly 3B does not require an oiling process, the fixed gasket automatic assembly device 33 of the second set of fixed gasket feeding assembly 3B does not have a gasket assembly oiling device.

[0246] In some embodiments, refer to Figure 9 The first set of fixed gasket feeding assembly 3A's fixed gasket automatic assembly device 33 also includes a gasket assembly slide electric cylinder 334, a first gasket assembly slide cylinder 335, and a second gasket assembly slide cylinder 336.

[0247] The first gasket assembly slide cylinder 335 and the second gasket assembly slide cylinder 336 are respectively installed on the horizontal movement end of the gasket assembly slide electric cylinder 334. The gasket assembly slide electric cylinder 334 drives the first gasket assembly slide cylinder 335 and the second gasket assembly slide cylinder 336 to move horizontally.

[0248] The gasket assembly vacuum suction head 331 is mounted on the lifting and lowering end of the first gasket assembly slide cylinder 335, and the first gasket assembly slide cylinder 335 drives the gasket assembly vacuum suction head 331 to move up and down.

[0249] The gasket assembly oil injection head 332 and the gasket assembly oil injection valve 333 are located on the lifting and lowering end of the second gasket assembly slide cylinder 336. The second gasket assembly slide cylinder 336 drives the gasket assembly oil injection head 332 and the gasket assembly oil injection valve 333 to move up and down together.

[0250] In some embodiments, the automatic gasket assembly device 33 of the second group of fixed gasket feeding assembly 3B, compared with the automatic gasket assembly device 33 of the first group of fixed gasket feeding assembly 3A, does not have a gasket assembly oil injection device, and therefore only has one gasket assembly slide cylinder, while the other structures are the same. Specifically:

[0251] The second set of fixed gasket feeding assembly 3B's fixed gasket automatic assembly device 33 also includes a second set of gasket assembly slide electric cylinders and a second set of gasket assembly slide pneumatic cylinders.

[0252] The second set of gasket assembly slide cylinders is located on the horizontal movement end of the second set of gasket assembly slide electric cylinders, and is driven by the second set of gasket assembly slide electric cylinders to perform horizontal movement. The second set of gasket assembly vacuum suction heads is located on the lifting movement end of the second set of gasket assembly slide cylinders, and is driven by the second set of gasket assembly slide cylinders to perform lifting movement.

[0253] In some embodiments, the automatic shim assembly device 33 of both the first group of shim feeding assemblies 3A and the second group of shim feeding assemblies 3B further includes a shim assembly laser ranging sensor. Taking the first group of shim feeding assemblies 3A as an example, refer to... Figure 9 The sensing end of the shim assembly laser rangefinder 337 faces downward and is used to detect the distance between it and the fixed shim below. The shim assembly laser rangefinder 337 is set on the lifting and lowering motion end of the first shim assembly slide cylinder 335. The first shim assembly slide cylinder 335 drives the shim assembly laser rangefinder 337 together with the shim assembly vacuum suction head 331 to move up and down.

[0254] When the gasket assembly vacuum suction head 331 moves above the fixed gasket cylinder 31, the distance between it and the fixed gasket below can be detected by the gasket assembly laser distance sensor 337. If the distance is not the preset distance, it is assumed that there is an incorrect height of the fixed gasket below or that there is no fixed gasket, and an alarm will be triggered. In this case, the gasket assembly vacuum suction head 331 will not perform the descent and suction operation, and a stop alarm will be triggered. If the distance is the preset distance, the gasket assembly vacuum suction head 331 can descend and suction the fixed gasket.

[0255] In some embodiments, the structures of the first group of carbon fiber friction plate feeding assemblies 4A and the second group of carbon fiber friction plate feeding assemblies 4B are similar to the structure of the first group of fixed gasket feeding assemblies 3A, specifically:

[0256] Both the first group of carbon fiber friction plate feeding assembly 4A and the second group of carbon fiber friction plate feeding assembly 4B include a carbon fiber friction plate cylinder, a carbon fiber friction plate dispensing device, and a carbon fiber friction plate automatic assembly device. The carbon fiber friction plate dispensing device includes a liftable friction plate dispensing and pushing block, which is located below the carbon fiber friction plate cylinder and moves the carbon fiber friction plate upward along the cylinder. The carbon fiber friction plate automatic assembly device includes a friction plate assembly vacuum suction head that can perform horizontal and vertical movements. The friction plate assembly vacuum suction head picks up the carbon fiber friction plate at the top of the carbon fiber friction plate cylinder and sends it to the damper housing on the product positioning fixture 9 inside the first or second carbon fiber friction plate feeding station.

[0257] In some embodiments, the carbon fiber friction plate cylinder adopts the same structure as the fixed gasket cylinder 31. In specific implementations, positioning ribs, positioning grooves, or other positioning components can be provided in the carbon fiber friction plate cylinder according to the different shapes of the carbon fiber friction plates.

[0258] The carbon fiber friction plate distribution device adopts the same structure as the fixed gasket distribution device 32.

[0259] The first carbon fiber friction plate feeding station is located next to the first fixed gasket feeding station. The automatic carbon fiber friction plate assembly device on the first carbon fiber friction plate feeding station is shared with the automatic fixed gasket assembly device 33 on the first fixed gasket feeding station. That is, the gasket assembly vacuum suction head 331 on the automatic fixed gasket assembly device 33 on the first fixed gasket feeding station is used to hold both the fixed gasket and the carbon fiber friction plate. The gasket assembly oil injection head 332 on the automatic fixed gasket assembly device 33 on the first fixed gasket feeding station performs oil injection after both the fixed gasket and the carbon fiber friction plate are assembled.

[0260] The automatic assembly device for carbon fiber friction plates at the second carbon fiber friction plate feeding station has the same structure as the automatic assembly device for fixed shims at the first fixed shim feeding station.

[0261] When the fixed gasket automatic assembly device 33 at the first fixed gasket feeding station is used together, refer to Figure 9The automatic assembly device 33 for fixed gaskets at the first fixed gasket feeding station also includes a common slide cylinder 338. The common slide cylinder 338 is located on the horizontal movement end of the gasket assembly slide cylinder 334, and the gasket assembly slide cylinder 334 drives the common slide cylinder 338 to move horizontally in the first direction. The first gasket assembly slide cylinder 335 and the second gasket assembly slide cylinder are respectively located on the horizontal movement end of the common slide cylinder 338. The gasket assembly slide cylinder 334 indirectly drives the first gasket assembly slide cylinder 335 and the second gasket assembly slide cylinder to move horizontally in the first direction through the common slide cylinder 338, and the common slide cylinder 338 drives the first gasket assembly slide cylinder 335 and the second gasket assembly slide cylinder to move horizontally in the second direction intersecting the first direction.

[0262] This embodiment achieves the shared purpose of the gasket assembly vacuum suction head 331 and the gasket assembly oil injection head 332 by adding a shared slide cylinder 338.

[0263] In another embodiment, the automatic assembly device for carbon fiber friction pads at the second carbon fiber friction pad feeding station can also be shared with the automatic assembly device 33 for fixed shims at the second fixed shim feeding station. In this case, the automatic assembly device 33 for fixed shims at the second fixed shim feeding station should have the same structure as the automatic assembly device 33 for fixed shims at the first fixed shim feeding station, that is, it should also have a shim assembly oiling device for oiling the assembled carbon fiber friction pads.

[0264] In some embodiments, the carbon fiber friction plate cylinder adopts the same structure as the fixed gasket cylinder 31.

[0265] The carbon fiber friction plate distribution device adopts the same structure as the fixed gasket distribution device 32.

[0266] Each carbon fiber friction plate automatic assembly device adopts the same structure as the fixed gasket automatic assembly device 33 on the first fixed gasket feeding station.

[0267] In this embodiment, the feeding of carbon fiber friction pads is achieved using a structure independent of the fixed pad feeding assembly.

[0268] In some embodiments, refer to Figure 10 The first group of carbon fiber friction plate feeding assembly 4A and the second group of carbon fiber friction plate feeding assembly 4B both include a carbon fiber friction plate secondary distribution device 41, which includes a secondary distribution pusher plate 411, a secondary distribution cover plate 412 and a secondary distribution pusher plate 413.

[0269] The top surface of the secondary material distribution and pushing plate 411 is provided with a secondary material distribution and pushing groove 4111, and one side of the secondary material distribution and pushing groove 4111 is an open opening.

[0270] The secondary material distribution cover plate 412 is located above the opening of the secondary material distribution push groove 4111. The distance from the bottom surface of the secondary material distribution cover plate 412 to the bottom of the opening of the secondary material distribution push groove 4111 is less than the thickness of two carbon fiber friction plates. In other words, only one carbon fiber friction plate can pass through the opening below the secondary material distribution cover plate 412.

[0271] The secondary material distribution pusher 413 can move horizontally. The secondary material distribution pusher 413 and the secondary material distribution pusher plate 411 are located on two opposite sides of the top of the carbon fiber friction plate cylinder. The openings of the secondary material distribution pusher 413 and the secondary material distribution pusher groove 4111 are arranged opposite to each other.

[0272] The uppermost carbon fiber friction plate in the carbon fiber friction plate cylinder is pushed out of the cylinder by the friction plate distribution and pushing block. The horizontal movement of the secondary distribution and pushing plate 413 pushes the pushed carbon fiber friction plate through the opening of the secondary distribution and pushing groove 4111 and pushes it into the secondary distribution and pushing groove 4111. The friction plate assembly vacuum suction head picks up the carbon fiber friction plate in the secondary distribution and pushing groove 4111 and sends it to the damper housing on the product positioning fixture 9 inside the first carbon fiber friction plate feeding station or the second carbon fiber friction plate feeding station.

[0273] Because the carbon fiber friction plates are relatively thin, when the vacuum suction head of the friction plate assembly is used to hold the carbon fiber friction plates, it is possible to hold two adjacent carbon fiber friction plates. In order to avoid this situation, this embodiment uses a carbon fiber friction plate secondary feeding device 41 to push a single carbon fiber friction plate into the secondary feeding groove 4111 before holding and feeding it, which can ensure that only one carbon fiber friction plate is sent to the damper housing.

[0274] In some embodiments, refer to Figure 10 The carbon fiber friction plate secondary material distribution device 41 also includes a secondary material distribution cylinder 414. The secondary material distribution pusher 413 is directly connected to or connected to the horizontal moving end of the secondary material distribution cylinder 414 through the secondary material distribution fixing plate. The secondary material distribution cylinder 414 drives the secondary material distribution pusher 413 to move horizontally.

[0275] In some embodiments, refer to Figure 1 , Figures 11 to 12The metal sheet feeding assembly 5 includes a metal sheet cylinder 51, a metal sheet dispensing device 52, and an automatic metal sheet assembly device. The metal sheet dispensing device 52 includes a liftable metal sheet dispensing and pushing plate 521. The metal sheet dispensing and pushing plate 521 is located below the metal sheet placed on the metal sheet cylinder 51 and can move the metal sheet upward along the metal sheet cylinder 51. The automatic metal sheet assembly device includes a metal sheet assembly vacuum suction head that can perform horizontal and vertical movements. The metal sheet assembly vacuum suction head picks up the metal sheet at the top of the metal sheet cylinder 51 and sends it to the damper housing on the product positioning fixture 9 inside the metal sheet feeding station.

[0276] In some embodiments, refer to Figure 12 The metal sheet dispensing device 52 also includes a metal sheet dispensing fixing seat 522 and a metal sheet dispensing thrust electric cylinder 523.

[0277] A metal sheet feed cylinder 51 is detachably mounted on the metal sheet feeding and fixing seat 522.

[0278] The lifting end of the metal sheet distribution thrust cylinder 523 passes through the metal sheet distribution fixing seat 522 and is directly connected to the metal sheet distribution push plate 521 above the metal sheet distribution fixing seat 522 or connected through the metal sheet distribution connecting plate. The metal sheet distribution thrust cylinder 523 drives the metal sheet distribution push plate 521 to perform lifting and lowering movements.

[0279] In some embodiments, refer to Figure 12 The metal sheet dispensing device 52 also includes a metal sheet dispensing proximity sensor 524, which is used to detect whether there is a metal sheet cylinder 51 on the metal sheet dispensing fixing seat 522. The metal sheet dispensing proximity sensor 524 is installed on the metal sheet dispensing fixing seat 522.

[0280] Only after the presence of the metal sheet feed cylinder 51 on the metal sheet feeder fixing seat 522 is detected can the metal sheet feeder pusher plate 521 be driven to move up and down. Of course, other sensors that detect the presence of the metal sheet feed cylinder 51 can also be used instead.

[0281] In some embodiments, refer to Figure 12 The metal sheet dispensing device 52 also includes two metal sheet dispensing slide blocks 525. Each of the two metal sheet dispensing slide blocks 525 is provided with a metal sheet dispensing slide 5251. The two metal sheet dispensing slide blocks 525 are respectively arranged opposite each other on the metal sheet dispensing fixing seat 522 at a preset distance, and the two metal sheet dispensing slides 5251 are arranged opposite each other.

[0282] Reference Figure 11The metal sheet cylinder 51 includes a metal sheet cylinder mounting plate 511 and a metal sheet guide shaft 512 disposed on the metal sheet cylinder mounting plate 511. The metal sheet cylinder mounting plate 511 is inserted into two metal sheet dispensing grooves 5251.

[0283] Reference Figure 12 The metal sheet feeding and pushing plate 521 is provided with a metal sheet feeding and pushing groove 5211 that is connected vertically. One side of the metal sheet feeding and pushing groove 5211 has an open opening. The metal sheet feeding and pushing groove 5211 is located between two metal sheet feeding slides 5251. When the metal sheet cylinder mounting plate 511 is inserted into the two metal sheet feeding slides 5251, the opening of the metal sheet feeding and pushing groove 5211 is sleeved outside the metal sheet guide shaft 512 to abut against the bottom surface of a metal sheet placed on the metal sheet guide shaft 512.

[0284] In some embodiments, several metal sheets can be stacked and sleeved on the metal sheet guide shaft 512. Positioning ribs, positioning grooves, or other positioning components can be provided on the outer periphery of the metal sheet guide shaft 512 according to the shape of the metal sheets. The length direction of the positioning ribs, positioning grooves, or other positioning components is the lifting direction, thereby achieving positioning of the sleeved metal sheets without affecting the upward movement of the metal sheets on the metal sheet guide shaft 512. The positioning ribs, positioning grooves, or other positioning components can also provide guidance during the upward movement of the metal sheets.

[0285] In some embodiments, refer to Figure 12 The metal sheet distribution slide block 525 is provided with one or more metal sheet distribution locking parts 5111 for locking the metal sheet cylinder mounting plate 511.

[0286] In specific implementation, the metal sheet distribution locking component 5111 can be connected to the metal sheet distribution slide block 525 by a locking bolt threaded through the metal sheet distribution slide block 525 and then abutting against the metal sheet cylinder mounting plate 511. Alternatively, a locking hole can be provided on the metal sheet cylinder mounting plate 511, and the metal sheet distribution locking component 5111 can be connected to the metal sheet distribution slide block 525 by a locking bolt threaded through the metal sheet distribution slide block 525 and then inserted into the locking hole to achieve locking.

[0287] In some embodiments, the automatic metal sheet assembly device adopts the same structure as the automatic fixed shim assembly device 33 on the first fixed shim feeding station, which will not be described in detail here.

[0288] In some embodiments, refer to Figure 1 , Figures 13 to 14The spring feeding assembly 6 includes a spring vibrating feeder 61, a spring dispensing device 62, and a spring automatic assembly device 63. The spring dispensing device 62 includes a spring receiving groove 621, which is used to receive springs fed from the spring vibrating feeder 61. The spring automatic assembly device 63 includes a spring assembly gripper 631 that can perform horizontal and vertical movements. The spring assembly gripper 631 clamps the springs in the spring receiving groove 621 and sends them to the damper housing on the product positioning fixture 9 inside the spring feeding station.

[0289] In some embodiments, refer to Figure 13 The spring material distribution device 62 also includes a spring material distribution slide cylinder 622, a spring material distribution rotary cylinder 623, a spring material distribution positioning block 624, and a spring material distribution proximity sensor 625.

[0290] The spring-loaded material distribution slide cylinder 622 can be installed at the spring feeding station via the spring-loaded material distribution bracket.

[0291] The spring-loaded rotary cylinder 623 is mounted on the horizontal movement end of the spring-loaded slide cylinder 622, and the spring-loaded slide cylinder 622 drives the spring-loaded rotary cylinder 623 to move horizontally.

[0292] The spring material distribution positioning block 524 is set on the rotating end of the spring material distribution rotary cylinder 623. The spring material distribution rotary cylinder 623 drives the spring material distribution positioning block 524 to rotate around the horizontal direction. The spring material distribution positioning block 524 is provided with a spring receiving groove 621.

[0293] The spring distribution proximity sensor 625 is used to detect whether a spring is being held on the spring receiving groove 621. The spring distribution proximity sensor 625 is set on the spring distribution positioning block 524 and faces into the spring receiving groove 621.

[0294] Initially, the spring receiving groove 621 faces and connects to the outlet of the spring vibrating material tray 61. When the spring distribution proximity sensor 625 detects that a spring is supported on the spring receiving groove 621, it drives the spring distribution slide cylinder 622 to move. The spring distribution slide cylinder 622 drives the spring distribution rotary cylinder 623 and the spring distribution positioning block 524 to move horizontally away from the spring vibrating material tray 61, so that the spring receiving groove 621 is away from the outlet of the spring vibrating material tray 61. The spring distribution rotary cylinder 623 drives the spring distribution positioning block 524 to rotate, so that the spring receiving groove 621 faces upward, so that the spring assembly gripper 631 can pick up the spring in the spring receiving groove 621.

[0295] When the spring distribution proximity sensor 625 detects that the spring on the spring receiving groove 621 has been removed by the spring assembly gripper 631, it sequentially drives the spring distribution rotary cylinder 623 and the spring distribution slide cylinder 622 to move, so that the spring receiving groove 621 is reoriented and connected to the outlet of the spring vibrating material tray 61 to receive the next spring.

[0296] In some embodiments, refer to Figure 14 The automatic spring assembly device 63 also includes a spring assembly slide electric cylinder 632, a spring assembly slide air cylinder 633, and a spring assembly gripper air cylinder 634.

[0297] The spring assembly slide electric cylinder 632 can be installed at the spring feeding station via the spring assembly bracket.

[0298] The spring assembly slide cylinder 633 is located on the horizontal movement end of the spring assembly slide electric cylinder 632, and the spring assembly slide electric cylinder 632 drives the spring assembly slide cylinder 633 to move horizontally.

[0299] The spring assembly gripper cylinder 634 is mounted on the lifting end of the spring assembly slide cylinder 633, and the spring assembly slide cylinder 633 drives the spring assembly gripper cylinder 634 to perform lifting and lowering movements.

[0300] The spring assembly jaw 631 is set on the jaw end of the spring assembly jaw cylinder 634, and the spring assembly jaw 631 is driven by the spring assembly jaw cylinder 634 to clamp or release the spring.

[0301] In some embodiments, refer to Figure 1 and Figure 15 The bottom cover feeding assembly 7 includes a bottom cover vibrating feeder 71, a bottom cover dispensing device, and a bottom cover automatic assembly device 72. The bottom cover dispensing device includes a bottom cover receiving groove for receiving bottom covers fed from the bottom cover vibrating feeder 71. The bottom cover automatic assembly device 72 includes a bottom cover assembly gripper 721 that can move horizontally, vertically, and rotate around the vertical direction. The bottom cover assembly gripper 721 clamps the bottom cover in the bottom cover receiving groove and sends it to the damper housing on the product positioning fixture 9 inside the bottom cover feeding station.

[0302] In this embodiment, since the bottom cover assembly gripper 721 that holds the bottom cover can rotate around the lifting direction, the automatic bottom cover assembly device 72 can perform a certain rotation action after placing the bottom cover into the damper housing to realize the pre-rotation of the bottom cover.

[0303] In some embodiments, the bottom cover dispensing device adopts the same as... Figure 5 The damper housing distribution device 22 shown has a similar structure, but differs from it in that the bottom cover receiving groove does not have a positioning groove, and the sensor uses a bottom cover distribution through-beam sensor for detection. Specifically:

[0304] The bottom cover material distribution device also includes a bottom cover material distribution slide cylinder, a bottom cover material distribution fixing seat, a bottom cover material distribution block, and a bottom cover material distribution through-beam sensor.

[0305] The bottom cover material distribution slide cylinder can be installed at the bottom cover feeding station via the bottom cover material distribution base plate.

[0306] The bottom cover material distribution fixing seat is connected to the horizontal movement end of the bottom cover material distribution slide cylinder via the bottom cover material distribution connecting frame. The bottom cover material distribution fixing seat is provided with a bottom cover receiving groove. The bottom cover receiving groove has an opening on the side facing the bottom cover vibrating material plate 71. The bottom cover receiving groove opening is connected to the bottom cover vibrating material plate 71.

[0307] The bottom cover material distribution block is located on the side of the bottom cover material distribution fixing seat, which is situated on the side of the bottom cover receiving groove opening. In practice, the bottom cover material distribution block can be fixed to the worktable by the bottom cover material distribution baffle, so that the bottom cover material distribution block is fixed relative to the bottom cover material distribution fixing seat.

[0308] The bottom cover distribution sensor is used to detect whether a bottom cover is being held in the bottom cover receiving groove. The sensor is mounted on the bottom cover distribution fixing base and faces the bottom cover receiving groove. Of course, other sensors that detect the presence of a bottom cover can also be used instead.

[0309] When the bottom cover material distribution sensor detects that a bottom cover is being received on the bottom cover receiving groove, it drives the bottom cover material distribution slide cylinder to move. The bottom cover material distribution slide cylinder drives the bottom cover material distribution fixing seat to move horizontally towards the bottom cover material distribution block. The bottom cover material distribution block blocks the opening of the bottom cover receiving groove, and the bottom cover material distribution fixing seat blocks the outlet of the bottom cover vibrating material plate 71 on one side facing the bottom cover vibrating material plate 71.

[0310] When the bottom cover distribution sensor detects that the bottom cover on the bottom cover receiving groove has been removed by the bottom cover automatic assembly device 72, it drives the bottom cover distribution slide cylinder to move. The bottom cover distribution slide cylinder drives the bottom cover distribution fixing seat to move horizontally away from the bottom cover distribution block. Then, the opening of the bottom cover receiving groove connects to the outlet of the bottom cover vibrating material tray 71 to receive the next bottom cover.

[0311] In some embodiments, the bottom cover feeding assembly 7 further includes a bottom cover detection assembly for detecting the angle of the bottom cover, the bottom cover detection assembly employing a method similar to... Figure 5 The damper housing detection assembly shown has a similar structure, but differs from it in that the bottom cover detection assembly uses a bottom cover detection module for image comparison. Specifically:

[0312] The bottom cover inspection assembly includes a bottom cover inspection lighting lamp, a bottom cover inspection camera, and a bottom cover inspection module. The bottom cover inspection lighting lamp is positioned below the bottom cover receiving slot to illuminate the bottom cover held in the slot. The bottom cover inspection camera is positioned above the bottom cover receiving slot and is used to acquire images of the bottom cover on the slot. The bottom cover inspection module is connected to the bottom cover inspection camera and receives the bottom cover images. The bottom cover inspection module compares the bottom cover images with preset bottom cover standard images and determines the rotation angle based on the angular difference between the two images. The bottom cover assembly gripper 721 can perform horizontal, vertical, and rotational movements around the vertical direction. By driving the bottom cover assembly gripper 721 to rotate by a certain angle, the bottom cover is placed into the damper housing on the product positioning fixture 9 at a preset angle.

[0313] Similar to the damper housing, the bottom cover also needs to be assembled in the damper housing at a preset angle. After the bottom cover detection component is designed as described above, it can be ensured that the bottom cover is placed in the damper housing on the product positioning fixture 9 at a preset angle.

[0314] In some embodiments, the automatic bottom cover assembly device 72 employs a method similar to... Figure 6 The damper housing automatic assembly device 23 shown has a similar structure, but differs from the damper housing automatic assembly device 23 in that the rotary electric cylinder and gripper cylinder of the bottom cover automatic assembly device 72 are integrated rotary gripper electric cylinders. Specifically:

[0315] Reference Figure 15 The automatic bottom cover assembly device 72 also includes a bottom cover assembly slide electric cylinder 722, a bottom cover assembly slide pneumatic cylinder 723, and a bottom cover assembly rotary gripper electric cylinder 724.

[0316] The bottom cover assembly slide electric cylinder 722 can be installed at the bottom cover feeding station via the bottom cover assembly bracket.

[0317] The bottom cover assembly slide cylinder 723 is located on the horizontal movement end of the bottom cover assembly slide electric cylinder 722, and the bottom cover assembly slide cylinder 723 is driven by the bottom cover assembly slide electric cylinder 722 to make horizontal movement.

[0318] The bottom cover assembly rotary gripper electric cylinder 724 is set on the lifting and lowering end of the bottom cover assembly slide cylinder 723, and the bottom cover assembly slide cylinder 723 drives the bottom cover assembly rotary gripper electric cylinder 724 to perform lifting and lowering movements.

[0319] The bottom cover assembly gripper 721 is mounted on the gripper end of the bottom cover assembly rotary gripper electric cylinder 724. The bottom cover assembly rotary gripper electric cylinder 724 drives the bottom cover assembly gripper 721 to rotate around the lifting direction and to grip or release the bottom cover.

[0320] In some embodiments, a bottom cover assembly linear guide rail is provided on the bottom cover assembly bracket, and the length direction of the bottom cover assembly linear guide rail is consistent with the horizontal movement direction of the bottom cover assembly slide cylinder 722. The bottom cover assembly slide cylinder 723 is connected to a bottom cover assembly connecting plate, and a bottom cover assembly slider is provided on the bottom cover assembly connecting plate. The bottom cover assembly slider is slidably connected to the bottom cover assembly linear guide rail, so that when the bottom cover assembly slide cylinder 723 moves horizontally, the bottom cover assembly slider slides along the bottom cover assembly linear guide rail.

[0321] In some embodiments, refer to Figure 15 The automatic bottom cover assembly device 72 also includes a bottom cover assembly pre-tightening buffer device, which includes a bottom cover assembly movable plate 725, one or more bottom cover assembly guide shafts 726, a bottom cover assembly fixed seat 727, one or more bottom cover assembly linear bearings 728, and one or more elastic elements 729.

[0322] The bottom cover assembly movable plate 725 is located below the bottom cover assembly fixed seat 727. The bottom cover assembly movable plate 725 is connected to the bottom cover assembly rotary gripper electric cylinder 724 through the electric cylinder assembly connecting plate. That is to say, the bottom cover assembly rotary gripper electric cylinder 724 is not directly connected to the lifting movement end of the bottom cover assembly slide cylinder 723.

[0323] The bottom end of the bottom cover assembly guide shaft 726 is fixedly connected to the bottom cover assembly movable plate 725. The bottom cover assembly guide shaft passes through the bottom cover assembly fixed seat 727, and the top end of the bottom cover assembly guide shaft 726 protrudes from the top of the bottom cover assembly fixed seat 727. That is to say, the bottom cover assembly guide shaft 726 can move up and down relative to the bottom cover assembly fixed seat 727. A limit cover 7261 is provided at the top end of the bottom cover assembly guide shaft. The limit cover 7261 is located above the bottom cover assembly fixed seat 727 and is used to prevent the bottom cover assembly guide shaft 726 from falling off the bottom cover assembly fixed seat 727. In order to further fix the bottom cover assembly guide shaft 726, the bottom cover assembly guide shaft 726 is connected to the bottom cover assembly fixed seat 727 through the bottom cover assembly linear bearing 728.

[0324] The bottom cover mounting fixing seat 727 is set on the lifting movement end of the bottom cover mounting slide cylinder 723. The bottom cover mounting slide cylinder 723 drives the bottom cover mounting fixing seat 727, the bottom cover mounting guide shaft 726, the bottom cover mounting movable plate 725, and the bottom cover mounting rotary gripper electric cylinder 724 to move up and down together.

[0325] With the above design, since the bottom cover assembly guide shaft 726 can move up and down relative to the bottom cover assembly fixed seat 727, the bottom cover assembly movable plate 725 and the bottom cover assembly rotary gripper electric cylinder 724 connected to the bottom cover assembly guide shaft 726 can also move up and down relative to the bottom cover assembly fixed seat 727.

A guide block 842 is detachably mounted on the top end of the torque test connecting shaft 841. The guide block 842 is located within the positioning receiving groove 8111 and is used to insert the finished product under test. Specifically, when the finished product is placed on the positioning receiving groove 8111, the metal piece in the finished product inserts into the guide block 842.

[0350] The torque test servo motor 843 is mounted on the torque test fixture 845.

[0351] The bottom end of the torque sensor 844 is connected to the motor shaft of the torque testing servo motor 843 via a coupling, and the top end of the torque sensor 844 is connected to the torque testing connecting shaft 841 via another coupling.

[0352] In this embodiment, a torque test is performed simultaneously with the bottom cover rotation device 83 rotating the bottom cover to the damper housing. During the torque test, the torque test servo motor 843 is driven to rotate, which in turn transmits the torque to the torque test connecting shaft 841 and the guide block 842. The guide block 842 drives the metal sheet inside the finished product to rotate. A spring installed inside the finished product restricts the bottom cover between the bottom cover and the fixed pad above. As the bottom cover is continuously rotated to the damper housing, the torque continuously increases. The torque sensor 844 obtains the current torque information and compares it with a preset torque threshold range in real time. If the current torque information is within the preset torque threshold range, the torque test of the finished product is considered qualified, the bottom cover rotation device 83 stops, and the capping action is completed. If the current torque information is outside the preset torque threshold range after a preset time, the torque test of the finished product is considered unqualified, the bottom cover rotation device 83 stops, and the capping action is completed.

[0353] In some embodiments, the finished product bottom cover rotation device 83 and the finished product torque testing device 84 both include a rotation detection device 85, which includes a rotation detection block 851 and a rotation through-beam sensor 852.

[0354] The rotating detection block 851 is sleeved on the bottom cover rotating connecting shaft 834 or the torque test connecting shaft 841.

(Refer to...) Figure 20The outer surface of the guide block 842 is provided with an anti-fooling outer surface 8421 that matches the anti-fooling inner surface. When the guide block 842 is inserted into the guide block insertion interface, the anti-fooling outer surface 8421 is inserted into the inner side of the anti-fooling inner surface.

[0358] When the assembly equipment assembles metal sheets of different shapes, the corresponding guide blocks 842 also have different shapes. For example, they may use... Figures 3(b) to 3(d) When the damper 10 is shown, its corresponding guide block is Figure 20 The guide block 842 has several teeth on its outer circumferential surface that correspond to the metal sheet and are inserted into several slots on the inner ring of the metal sheet. When the shape of the metal sheet is different, the size and shape of the corresponding guide block, as well as the number and shape of the teeth, are all different.

[0359] When different metal pieces need to be assembled, the guide block needs to be replaced. Therefore, this embodiment uses a foolproof design to facilitate the replacement of the guide block without causing the guide block to fail to connect to the metal piece.
