Description

Technical Field

[0001] This invention belongs to the field of wind turbine component assembly technology, specifically a bearing assembly line. Background Technology

[0002] With the rapid development of modern industrial production, cooling fans, as key components of electronic devices, especially those used in laptops, have their bearings' assembly efficiency and precision directly impacting product quality and production efficiency. Traditional bearing assembly methods involve multiple components, such as the housing, wear plates, washers, rotor, and copper cap. The assembly of these components must be completed sequentially on different machines, and after each component is assembled, the product must be transferred to another machine for the next process. This assembly method is not only cumbersome and time-consuming but also occupies a significant amount of production space, reducing production efficiency. Furthermore, frequent equipment changes and manual operations increase the error rate during assembly, affecting the overall product quality. Therefore, developing an automated bearing assembly line that integrates multiple component assembly stations is particularly important. Summary of the Invention

[0003] The purpose of this invention is to overcome the shortcomings of existing technologies and provide a bearing assembly line that enables rapid and accurate assembly of components, improves production efficiency, reduces production space occupation, and lowers the error rate, thereby meeting the demands of modern industrial production for efficient and high-precision assembly.

[0004] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0005] A bearing assembly line, wherein the bearing includes a housing, wear-resistant plates, washers, rotors and copper caps assembled sequentially in the housing, and includes a conveying mechanism and a housing loading station, a wear-resistant plate assembly station, a washer assembly station, a rotor assembly station, a copper cap assembly station, a capping station and an unloading station arranged sequentially along the conveying direction of the conveying mechanism.

[0006] Both the shell loading station and the unloading station are equipped with a first feeding mechanism, a first transfer mechanism, and a first transfer mechanism. The first feeding mechanism has multiple trays stacked on top of each other. The first feeding mechanism is equipped with a first supporting claw that can move along the X-axis and support the bottom of the trays. The first transfer mechanism can move along the Y-axis between the first transfer position and the bottom of the first feeding mechanism. It is equipped with a liftable first pallet assembly. The first pallet assembly can be manipulated to move to the bottom of the first feeding mechanism and raised to a preset height. When the first supporting claw moves to the point of disengaging from the bottom of the trays, the entire stack of trays descends and is supported on the upper side of the first pallet assembly. The first pallet assembly can be manipulated to descend and reset after the first supporting claw supports the bottom of the second-to-last tray, so as to receive the bottom tray and transport it to the first transfer position. Then, the first transfer mechanism of the shell loading station transfers the shell on the tray to the carrier of the conveying mechanism and transports it to the next station. Alternatively, the first transfer mechanism of the unloading station transfers the bearing that has been assembled on the carrier to the tray.

[0007] The wear-resistant sheet assembly station, gasket assembly station, and copper cover assembly station are all equipped with a vibratory feeder, a second transfer mechanism, a first top visual recognition module, and a first bottom visual recognition module. The vibratory feeder is used to output parts in a preset posture. The first top visual recognition module is used to obtain the coordinates of the parts in the preset posture. The first bottom visual recognition module is used to obtain the offset coordinates of the parts on the gripper. The second transfer mechanism is equipped with a movable gripping device. The gripping device is equipped with several grippers. The gripping device can be controlled to drive each gripper to grip the parts that conform to the preset posture according to the signal output by the first top visual recognition module, so that each gripper passes through the first bottom visual recognition module in sequence. The first bottom visual recognition module obtains the offset coordinates of the parts on each gripper. The gripping device transfers the parts to the carrier of the conveying mechanism in sequence for assembly according to the offset coordinates of each part.

[0008] The rotor assembly station is equipped with a second feeding mechanism, a second transfer mechanism, a second top visual recognition module, and a second bottom visual recognition module. The second feeding mechanism has multiple stacked trays and is equipped with a third supporting claw that can move along the X-axis and supports the bottom of the trays. The second transfer mechanism can move along the Y-axis between a second transfer position and the bottom of the second feeding mechanism. It is equipped with a liftable second pallet assembly. The second pallet assembly can be manipulated to move to the bottom of the second feeding mechanism and rise to a preset height. When the third supporting claw moves away from the bottom of the tray, the entire stack of trays descends and is supported on the upper side of the second pallet assembly. The tray assembly can be controlled to descend and reset after being supported by the third support claw at the bottom of the penultimate tray, so as to receive the bottom tray and transport it to the second transfer position. The second top vision recognition module is used to obtain the rotor coordinates in the tray, and the second bottom vision recognition module is used to obtain the offset coordinates of the rotor on the gripper. The gripping device can be controlled to drive each gripper to grip the rotor on the tray according to the signal output by the second top vision recognition module, so that each gripper passes through the second bottom vision recognition module in sequence. The second bottom vision recognition module obtains the offset coordinates of the rotor on each gripper. The gripping device transfers the rotors to the carrier of the conveying mechanism in sequence for assembly according to the offset coordinates of each rotor.

[0009] The capping station is equipped with an operating module and a driving mechanism. The operating module includes a fixed base plate, and a pressing mechanism and an oil spraying mechanism disposed on the fixed base plate. The pressing mechanism is equipped with several pressure heads that can move synchronously along the Z-axis direction, and the oil spraying mechanism is equipped with several oil nozzles that can move synchronously along the Z-axis direction. The driving mechanism can controllably drive the operating module to move so that after the pressing mechanism is moved above the bearing, the pressure heads move down along the Z-axis and press against the copper cap, or after the oil spraying mechanism is moved above the bearing, the oil nozzles move down along the Z-axis and connect with the central hole on the copper cap to spray oil into the housing.

[0010] Compared with the prior art, the bearing assembly line provided by the present invention integrates the housing loading station, the wear-resistant plate, washer, rotor, and copper cover assembly station, the copper cover pressing, oil spraying, and inspection station, and the unloading station. The above stations are connected by a conveying mechanism, realizing the automated assembly of bearings. This not only effectively reduces the space occupied by the equipment, but also reduces the time spent transferring parts between various equipment, effectively improving the assembly efficiency.

[0030] The following describes a preferred embodiment of the present invention in conjunction with the accompanying drawings.

[0031] See Figure 1 and Figure 2 This embodiment provides a bearing assembly line, specifically a bearing for a cooling fan, which includes a housing f1, wear-resistant plates f2, washers f3, rotors f4, and copper caps f5 sequentially assembled inside the housing f1. The assembly process of this assembly line includes: loading the housing f1 → assembling the wear-resistant plates f2 into the housing f1 → assembling the washers f3 into the housing f1 → assembling the rotors f4 into the housing f1 → sealing the upper opening of the housing f1 with the copper caps f5 → pressing the copper caps f5 onto the housing f1 → injecting lubricating oil into the housing f1 → checking whether the assembly is qualified. It is equipped with a conveying mechanism 8, and housing loading station 1, wear-resistant plate assembly station 2, washer assembly station 3, rotor assembly station 4, copper cap assembly station 5, capping station 6, unloading station 7, and a controller arranged sequentially along the conveying direction of the conveying mechanism 8.

[0032] See Figure 1 , Figure 23 and Figure 24 The conveying mechanism 8 is equipped with a carrier 9. The conveying mechanism 8 drives the carrier 9 to move intermittently and sequentially to the following stations: housing loading station 1, wear-resistant sheet assembly station 2, washer assembly station 3, rotor assembly station 4, copper cover assembly station 5, pressure cap station 6, and unloading station 7, thereby realizing the following processes respectively: when it reaches the housing loading station 1, the housing is transferred to the carrier 9; when it reaches the wear-resistant sheet assembly station 2, the wear-resistant sheet is assembled into the housing; when it reaches the washer assembly station 3, the washer is assembled into the housing. Inside, when the rotor reaches the rotor assembly station 4, the rotor is assembled inside the housing. When it reaches the copper cover assembly station 5, the copper cover is sealed on the upper opening of the housing. When it reaches the cover pressing station 6, the copper cover is pressed tightly on the upper opening of the housing. Then, lubricating oil is injected into the housing at this station, and the copper cover is checked to see if it is assembled correctly. If it is qualified, it is transported to the unloading station 7, and the assembled bearing is transferred to the unloading station 7 for unloading and recycling. If it is not qualified, it is taken directly from the carrier 9 at the cover pressing station 6.

[0033] The following describes the shell loading station 1 and unloading station 7.

[0034] See Figure 1 , Figures 3 to 6 Both the loading station 1 and the unloading station 7 are equipped with a first unloading mechanism a1, a first receiving mechanism a3, a first transfer mechanism a2, a first transfer mechanism a4, and a vision recognition mechanism a5, such as Figure 4 and Figure 5 As shown, the first feeding mechanism a1 and the first receiving mechanism a3 are arranged along the Y-axis. The order in which they are arranged is not limited in this patent. Both the first feeding mechanism a1 and the first receiving mechanism a3 have the function of storing the tray a0. The first feeding mechanism a1 is used to output the tray, while the first receiving mechanism a3 is used to retrieve the tray a0. The first transfer mechanism a2 can reciprocate along the Y-axis between the first transfer position a01 and the bottom of the first feeding mechanism a1, selectively moving to the first feeding machine. The first transfer mechanism a2 receives the tray a0 stored on the first unloading mechanism a1 at its bottom, or moves to the bottom of the first receiving mechanism a3 to return the tray a0 to the first receiving mechanism a3. After receiving the tray a0, the first transfer mechanism a2 moves away from the first unloading mechanism a1 along the Y-axis. The first transfer mechanism a4 is used to transfer components on the tray a0 to the corresponding workstation, or to transfer components onto the tray a0 for recycling. For example, at the housing loading station 1, the first transfer mechanism a4... 4. The components on Tray a0 can be transferred to the carrier 9 of the conveying mechanism 8, and then transported to various downstream workstations for subsequent assembly via the conveying mechanism 8. When the components on Tray a0 are consumed, the first transfer mechanism a2 transfers the empty Tray a0 to the bottom of the first receiving mechanism a3, thereby returning the empty Tray a0 to the receiving machine a3. When the carrier 9 loaded with components is transported to the last workstation, such as the unloading station 7 of the present invention, the components are transferred to the carrier 9 of the unloading station 7 via the first unloading mechanism a2. The material handling mechanism a1 outputs an empty tray a0. The first transfer mechanism a3 at this station transports the empty tray a0 to the position of the connecting carrier 9. The first transfer mechanism a4 transfers the assembled bearings from the carrier 9 to the empty tray a0 for unloading. This process continues until the tray a0 is fully loaded. When the tray a0 is fully loaded, the first transfer mechanism a2 transfers the fully loaded tray a0 to the bottom of the first receiving mechanism a3 at this station, thereby returning the fully loaded tray a0 to the first receiving mechanism a3 for recycling.

[0035] The specific structure of the first feeding mechanism a1 is described below:

[0036] See Figure 5 , Figure 6 and Figure 9The first feeding mechanism a1 is equipped with a first material rack a11 for accommodating the tray a0 and a first base a16 connected to the bottom of the first material rack a11. The first material rack a11 includes first placement rods a111 arranged around the first base a16 and extending upward. The first placement rods a111 enclose a space for accommodating the tray a0. The first base a16 includes first base plates a161 arranged opposite to each other. A channel is formed between the two first base plates a161 for the passage of the first transfer mechanism a2. The upper end of each first base plate a161 is equipped with a first support claw a12 and a pull claw a13 arranged along the Y-axis direction.

[0037] See Figure 9 Tray discs a0 are stacked in the first material rack a11. A slot a01 is formed on the side between each two adjacent Tray discs a0. The first support claw a12 and the pull claw a13 can move along the X-axis to approach the Tray disc a0 and insert into the slot a01 or move away from the Tray disc a0 and disengage from the slot a01. In one specific implementation, the first substrate a161 is provided with a first driving cylinder a162 for driving the first support claw a12 to move along the X-axis direction, and a second driving cylinder a163 for driving the pull claw a13 to move along the X-axis direction. The upper surfaces of the first support claw a12 and the pull claw a13 are set as horizontal planes, and the bottom surfaces of the two near the Tray disk a0 are set as inclined planes that slope upward from the outside to the inside. The inclined planes form a wedge structure. When the support claw and the pull claw a13 are inserted into the slot a01, as the insertion depth increases, the two Tray disks a0 will separate under the action of the wedge structure so that the bottom Tray disk a0 can be output later.

[0038] See Figure 5 As an improved solution, two or more first support claws a12 are spaced apart along the Y-axis, and pull claws a13 are arranged between the two first support claws a12. The above arrangement can effectively support the entire stack of trays a0, and make it easier to separate the two trays a0 when inserting into the slot a01.

[0039] See Figures 5 to 10 The first feeding mechanism a1 is also equipped with a trigger part a14 connected to the pull claw a13, and an elastic component a15 that drives the pull claw a13 to move downward and reset. The trigger part a14 extends laterally to the bottom of the first material rack a11. The first transfer mechanism a2 can be manipulated to move to the bottom of the first material rack a11, and it is equipped with a liftable first tray assembly a21. The bottom of the first tray assembly a21 is equipped with a drive part a22 located below the trigger part a14. Figure 7As shown, the first tray assembly a21 can be manipulated to move upward to a preset height, causing the drive unit a22 to push against the trigger unit a14 and drive the pull claw a13 to move upward. When the first support claw a12 moves along the X-axis to disengage from the tray a0, the tray a0 descends and is supported on the upper side of the first tray assembly a21, as shown. Figure 8 As shown, the first tray assembly a21 can be manipulated to move downward and reset after the first supporting claw a12 and the pull claw a13 move to insert into the slot a01, so that the pull claw a13 is reset downward under the action of the elastic component a15, so as to pull the tray a0 located at the bottom end towards the first tray assembly a21.

[0040] The housing loading station 1 and unloading station 7 provided in this embodiment are equipped with a first supporting claw a12 and a pull claw a13 at the bottom of the first material rack a11. Utilizing the lifting function of the first pallet assembly a21, the first supporting claw a12 supports the entire stack of trays a0 when it releases the stack, causing the trays a0 to descend by one layer. When the first supporting claw a12 inserts into the bottom of the second-to-last layer of trays a0, it again supports the stack above the bottommost tray a0. Simultaneously, the pull claw a13 is also moved upwards as the first pallet assembly a21 rises. After the pull claw a13 inserts into the bottom of the second-to-last layer of trays a0, the first pallet assembly a21... As it moves downwards, it will also reset downwards due to the action of the elastic component a15, thereby removing the bottom tray a0 and dropping it onto the first tray component a21, so as to transfer it to the corresponding position and realize the loading or unloading operation. The above structure realizes the automatic unloading of the tray a0, thus eliminating the need for manual handling. Moreover, since the tray a0 is a relatively soft, long, and thin container, it is difficult to separate the stacked trays a0 even manually. This invention uses the pull claw a13 as an aid, which can directly separate the tray a0 as the first tray component a21 descends, not only realizing automated unloading, but also improving the unloading efficiency.

[0041] See Figure 9 Regarding the mounting method of the pull claw a13, this embodiment provides the following specific configuration: a bracket a164 that can move along the Z-axis is mounted on the first substrate a161, the pull claw a13 is mounted on the bracket a164, the first substrate a161 has a through hole a165, the drive unit a22 is connected to the bracket a164 and extends through to the bottom of the tray a0, and the elastic component a15 includes a tension spring a151 that connects the first substrate a161 and the bracket a164.

[0042] See Figure 7As an improved solution, a buffer a166 is provided on the first substrate a161 below the driving part a22. When the driving part a22 moves down to reset, the buffer a166 can prevent the driving part a22 from directly hitting the through hole a165 and avoid damage.

[0043] See Figure 5 The first receiving mechanism a3 can be located in front of or behind the first discharging mechanism a1. It includes a second material rack a31 for accommodating the tray a0, a second base a32 connected to the bottom of the second material rack a31, and a second supporting claw a33 on the second base a32 for supporting the bottom of the tray a0. The second material rack a31 includes second placement rods a311 arranged around the second base a32 and extending upwards. The second placement rods a311 enclose a space for accommodating the tray a0. The space includes a second base a32 comprising two opposing second substrates a321, with a channel formed between the two second substrates a321 for the passage of the first transfer mechanism a2. Each second substrate a321 has a second support claw a33 at its upper end, the second support claw a33 having a degree of freedom to rotate upwards about the Y-axis. The first transfer mechanism a2 can be manipulated to move to the bottom of the second rack a31, so that the first tray assembly a21 transfers the tray a0 to the bottom of the second rack a31. Figures 13 to 14 As shown, the second support claw a33 can be manipulated to be pushed upward and flipped by the tray a0 when the first tray assembly a21 rises, so that the tray a0 can be inserted into the second material rack a31 on the upward side. When the first tray assembly a21 moves downward, the second support claw a33 flips downward and resets, so that the tray a0 is supported on the upper side of the second support claw a33.

[0044] See Figure 11 and Figure 12As a specific arrangement of the second supporting claw a33, a first rotating seat a322 is disposed on the upper end of the second base plate a321, and the second supporting claw a33 is rotatably mounted on the first rotating seat a322. A first limiting frame a323 is disposed on the outer side of the first rotating seat a322. The first limiting frame a323 has a first upper blocking part a323a and a first lower blocking part a323b arranged longitudinally at intervals. The outer end of the second supporting claw a33 is disposed with a first limiting part a331 extending between the first upper blocking part a323a and the first lower blocking part a323b. A limiting part a331 swings between the first upper blocking part a323a and the first lower blocking part a323b as the second supporting claw a33 flips. The second supporting claw a33, as described above, can only swing between the first upper blocking part a323a and the first lower blocking part a323b. This limitation on its swing amplitude serves to support the entire stack of trays a0, and can also flip upwards when pushed to form an entrance for the trays a0 to be inserted. When the tray moves downwards to reset, it can swing downwards to reset under the weight of the trays a0, forming a... Figure 11 The plane support angle shown is used to re-support the entire stack of Tray disks a0.

[0045] The order in which the first feeding mechanism a1 and the first receiving mechanism a3 are set up is explained below:

[0046] like Figure 4As shown, when the first feeding mechanism a1 is located behind the first receiving mechanism a3, i.e., away from the first transfer mechanism a2, it serves as the shell loading station 1. The operator stacks multiple trays a0 containing shells within the first rack a11. When loading is required, the first transfer mechanism a2 moves to the bottom of the first feeding mechanism a1, and the first pallet assembly a21 is raised to a certain height. Simultaneously, the trigger a14 drives the pull claw a13 upwards. Subsequently, the first supporting claw a12 moves along the X-axis away from the trays a0, causing the entire stack of trays a0 to descend and fall onto the first pallet assembly a21. Then, the first supporting claw a12 and the pull claw a13 move upwards. 13 moves along the X-axis toward the direction of the tray a0 and inserts into the slot a01. When the first tray assembly a21 moves down to reset, the pull claw a13 resets down under the action of the elastic component a15 to remove the bottom tray a0 and place it on the first tray assembly a21. At this time, the remaining trays a0 are supported by the first support claw a12, thus completing the unloading of the tray a0. Then, the first transfer mechanism a2 takes the unloaded tray a0 away from the first unloading mechanism a1, and the first transfer mechanism a4 can transfer the shell on the tray a0 to the corresponding place, such as the carrier 9 of the conveying mechanism 8, and transfer it to various workstations. When the shell on the Tray a0 is exhausted, the first transfer mechanism a2 moves the Tray a0 to the bottom of the first receiving mechanism a3. The first pallet assembly a21 rises, causing the Tray a0 to push the second support claw a33 upwards so that the Tray a0 enters the second material rack a31 and is placed at the bottom of its stack. Then, the first pallet assembly a21 descends and resets, causing the second support claw a33 to swing downwards and reset, thereby lifting the entire stack of empty Tray a0. This cycle repeats. The above-mentioned placement of the first material release mechanism a1 at the rear end makes it easier for engineers to put the fully loaded Tray a11 into the first material rack a11.

[0047] like Figure 5As shown, when the first unloading mechanism a1 is located in front of the first receiving mechanism a3, i.e., close to the first transfer mechanism a2, it serves as the unloading station 7. The operator stacks multiple empty trays a0 within the first rack a11. After the bearings are assembled, the first transfer mechanism a4 returns the assembled bearings to the empty trays a0 located on the first transfer mechanism a2. When the trays a0 are fully loaded, the first transfer mechanism a2 moves the fully loaded trays a0 to the bottom of the first receiving mechanism a3. Subsequently, the first pallet assembly a21 rises, pushing the trays a0 upwards to open the second support claw a33, allowing the trays a0 to enter the second rack a31 and be placed at the bottom of its stack. Then, the first pallet assembly a21 descends to reset, causing the second support claw a33 to swing downwards to reset, thereby lifting the entire stack of fully loaded trays a0, thus completing the unloading operation of the assembled bearings. Then, the first transfer mechanism a2 moves to the bottom of the first unloading mechanism a1. The first tray assembly a21 is lifted to a certain height, and at the same time, the trigger part a14 drives the pull claw a13 to move upward. Then, the first support claw a12 moves away from the tray a0 along the X-axis, so that the entire stack of trays a0 falls down onto the first tray assembly a21. Then, the first support claw a12 and the pull claw a13 move towards the tray a0 along the X-axis and insert into the slot a01. When the first tray assembly a21 moves down to reset, the pull claw a13 resets downward under the action of the elastic component a15, so as to remove the bottom tray a0 and place it on the first tray assembly a21. At this time, the remaining trays a0 are supported by the first support claw a12, thus completing the unloading of the trays a0. Then, the first transfer mechanism a2 takes the unloaded trays a0 away from the first unloading mechanism a1, and the first transfer mechanism a4 continues to transfer the assembled bearings to the empty trays a0, and so on. The arrangement of the first feeding mechanism a1 and the first receiving mechanism a3 ensures that the tray containing the parts is always kept at the end, allowing workers to transfer it.

[0048] See Figure 11 The first tray assembly a21 includes a liftable first bracket a211. The first bracket a211 has first protrusions a212 extending upward on both sides. A first suction cup a213 located on the upper side of the first bracket a211 is disposed between the first protrusions a212. The first suction cup a213 makes it easier to remove the tray a0 from the first feeding mechanism a1. The space between the first protrusions a212 on both sides is used to place the tray a0 and can prevent the tray a0 from shifting.

[0049] See Figure 3 and Figure 11The first transfer mechanism a4 is equipped with a movable robotic arm a41 and two opposing liftable base trays a42. The first transfer mechanism a2 can be manipulated to connect the first tray assembly a21 between the two base trays a42, so that the base trays a42 can support the tray a0 located on the first tray assembly a21. The visual recognition mechanism a5 is used to obtain the coordinate information of the tray a0 on the first tray assembly a21. The robotic arm a41 grabs materials and transfers them according to the coordinate information. The transfer includes transferring parts from the tray a0 to other places, such as the carrier 9, or transferring parts from other places to the tray a0. For example, transferring assembled parts from the carrier 9 to the empty tray a0 for collection to complete the unloading and loading of parts. Since the two sides of the tray a0 protrude from the first tray assembly a21, the base trays a42 can effectively support the tray a0 from both sides when the robotic arm a41 picks up and puts down parts.

[0050] The following describes the assembly stations for wear-resistant plates (station 2), washers (station 3), rotors (station 4), and copper caps (station 5). illustrate.

[0051] See Figure 1 , Figure 15 The wear-resistant sheet assembly station 2, the washer assembly station 3, and the copper cover assembly station 5 are all equipped with a first frame b1, a vibratory feeder b2 mounted on the first frame b1, a second transfer mechanism b3, a first bottom visual recognition module b4, and a first top visual recognition module b5. The vibratory feeder b2 is equipped with a hopper b21, a vibratory plate b22, and a channel b23 connecting the hopper b21 and the vibratory plate b22. The vibratory plate b22 can controllably vibrate the parts output from the hopper b21 through the channel b23 to a preset posture. The first top visual recognition module b5 is used to obtain the coordinates of the parts in the preset posture, and the first bottom visual recognition module b4 is used to obtain the offset coordinates of the parts on the gripper b32. The acquisition method of the visual recognition module involved in this invention is not the inventive point of this invention, so it will not be described in detail.

[0052] See Figure 15 and Figure 16The second transfer mechanism b3 is equipped with a movable gripping device b31, which has several grippers b32. The gripping device b31 can be controlled to drive each gripper b32 to grip parts (wear-resistant plates, washers, and copper caps) that conform to a preset posture according to the signal output by the first top visual recognition module b5. Each gripper b32 passes through the first bottom visual recognition module b4 in sequence. The first bottom visual recognition module b4 obtains the offset coordinates of the parts on each gripper b32. The gripping device b31 transfers the parts to the carrier 9 of the conveying mechanism 8 in sequence according to the offset coordinates of each part for assembly.

[0053] See Figure 17 and Figure 18 The rotor assembly station 4 is equipped with a second frame c1, a second feeding mechanism c2, a second transfer mechanism c3, a second transfer mechanism c3, a second top visual recognition module c4, and a second bottom visual recognition module c5. The second feeding mechanism c2 is equipped with a third material rack c22 and third support claws c21 on opposite sides of the bottom of the third material rack c22. The third material rack c22 is used to accommodate multiple stacked material trays, with slots formed between each pair of adjacent material trays. The third support claws c21 can move along the X-axis and support the bottom of the material trays to approach the material trays and insert into the slots, or move away from the material trays and disengage from the slots. The second transfer mechanism c3 can move along the Y-axis between the second transfer position c01 and the bottom of the third material rack c22. It is equipped with a liftable second tray assembly c31. The second tray assembly c31 can be manipulated to move to the bottom of the third material rack c22 and raised to a preset height. When the third support claws c21 move to disengage from the trays... When the material tray is at the bottom, the entire stack of material trays descends and is supported on the upper side of the second pallet assembly c31. The second pallet assembly c31 can be manipulated to descend and reset after being supported by the third support claw c21 at the bottom of the penultimate layer of material trays, so as to receive the bottommost material tray and transport it to the second transfer position c01.

The fourth support claws c62 have the freedom to rotate upward around the Y-axis. The second transfer mechanism c3 can be manipulated to move to the bottom of the fourth material rack c61. The fourth support claws c62 can be manipulated to be pushed upward by the material tray when the second pallet assembly c31 rises, so that the material tray can be inserted into the fourth material rack c61 upward. When the second pallet assembly c31 moves downward, the fourth support claws c62 rotate downward and reset, so that the material tray is supported on the upper side of the fourth support claws c62.

[0062] See Figures 17 to 19 The second receiving mechanism c6 further includes a second rotating seat c63 disposed on the side of the fourth material rack c61.

A buffer spring d225 abuts between the pressure head d221 and the first support frame d223. The buffer spring d225 can prevent the pressure head d221 from directly colliding rigidly with the copper cover, thus preventing damage to the copper cover. The first guide post d224 can make the first support frame d223 move more smoothly and prevent jamming.

The second support frame d233 is slidably mounted on the second guide post d234. The second guide post d234 allows the second support frame d233 to move more smoothly and prevents it from jamming.

[0068] The capping station 6 also includes a removal mechanism d24 located in front of the pressing mechanism d22 and a detection visual recognition module (not shown in the figure) positioned above the carrier 9. The removal mechanism d24 is equipped with several adsorption components d241 that can move synchronously along the Z-axis. The detection visual recognition module is used to acquire an image of the copper cap on the housing and transmit it to the controller to determine whether the copper cap installation is qualified. The drive mechanism d3 can be controlled to drive the removal mechanism d24 to move above the copper cap when the controller determines that the copper cap installation is unqualified, and move it downward along the Z-axis to adsorb the corresponding bearing, thereby removing the bearing from the corresponding carrier 9. The detection visual recognition module takes a picture of the copper cap from a top-down angle and compares it with a preset image to determine whether the copper cap installation is qualified. This technology is an existing judgment method and will not be described in detail again. By setting the removal mechanism d24, unqualified bearings can be removed, ensuring the product qualification rate.

[0069] The removal mechanism d24 further includes a removal cylinder d242 fixedly mounted on the fixed base plate d21, a third support frame d243 connected to the output end of the removal cylinder d242, and the plurality of adsorption elements d241 connected to the bottom end of the third support frame d243.

[0070] The following describes the conveying mechanism 8.

[0071] See Figure 1 , Figure 23 and Figure 24 The conveying mechanism 8 includes conveying modules e1 respectively disposed on the housing loading station 1, wear-resistant sheet assembly station 2, gasket assembly station 3, rotor assembly station 4, copper cover assembly station 5, pressure cap station 6 and unloading station 7. Two adjacent conveying modules e1 are connected. Each conveying module e1 includes a conveyor belt e2 for conveying the carrier 9 along the X-axis direction and a lifting device e3. The lifting device e3 is used to push the carrier 9 upward away from the conveyor belt e2. The lifting device e3 includes a lifting cylinder e31 and a push plate e32 disposed on the upper end of the lifting cylinder e31 and driven to rise and fall by the lifting cylinder e31. The upper side of the push plate e32 is provided with a positioning pin e34 for cooperating with the carrier 9. A limit block e33 is provided above the conveyor belt e2.

The limiting member e353 and the limiting seat e351 are hinged between the roller e354 and the claw e355. The limiting seat e351 is provided with a spring that abuts against the bottom of the claw e355. The elastic buffer e356 drives the limiting member e353 to swing upward and reset. The anti-return device e36 is equipped with a floating pawl e361. The upper end surface of the pawl e361 is set as an inclined surface that slopes upward along the conveying direction of the conveyor belt e2. When the carrier 9 moves along the conveying direction of the conveyor belt e2 and contacts the rear end of the pawl e361, it can press down on the pawl e361, thereby causing the pawl e361 to descend and pass normally. When the carrier 9 moves in the opposite direction of the conveying direction of the conveyor belt e2, it is blocked by the front end of the pawl e261 and cannot move further, thereby achieving the anti-return effect and ensuring that the carrier 9 will not shift.
