Description

Technical Field

[0001] This utility model relates to the field of waterproof connector assembly technology, and more specifically to an automatic waterproof connector assembly machine. Background Technology

[0002] A waterproof connector is a type of connector with waterproof functionality, capable of maintaining stable electrical connections in humid, watery, or underwater environments. A waterproof connector includes a main body housing, a flat washer, a waterproof ring, a nut, and a bolt. The flat washer is fitted over the main body housing, the waterproof ring is located inside the main body housing, and the nut and bolt are screwed onto the outer ends of the main body housing, thus enabling the assembly of the waterproof connector.

[0003] Currently, Chinese patent application number 2024111852297 discloses an automatic assembly machine for waterproof connectors. It includes a base, a positioning component, feeding component one, feeding component two, feeding component three, a flipping component, a tightening component one, feeding component four, feeding component five, tightening component two, and an unloading component. The positioning component includes a turntable, positioning seats, positioning rod one, and positioning rod two. Multiple positioning seats are arranged circumferentially on the turntable, and each positioning seat is vertically connected to positioning rod one and positioning rod two. The flipping component allows the outer casing at one positioning rod to be flipped to the position of positioning rod two for corresponding assembly. Although this solves... While existing technologies address the issue of slow manual assembly, they still have drawbacks. The positioning base has two mounting points for the main body shell, increasing the required size and installation space. Furthermore, the numerous feeding and assembly processes, each requiring a corresponding positioning base, further increase the number of bases. When the turntable size is small, the distance between adjacent positioning bases is narrow, leading to crowded installations of components, potential interference between adjacent processes, and difficulty in maintenance. Increasing the turntable size to increase the distance between adjacent positioning bases further increases the overall installation space required for the equipment, thus raising the company's operating costs. Utility Model Content

[0004] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide an automatic assembly machine for waterproof joints that occupies little space, has a simple structure, is easy to maintain, and has high processing efficiency.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an automatic assembly machine for waterproof joints, comprising a worktable, a positioning component, a flat washer feeding component, a main body feeding component, a waterproof ring feeding component, a nut feeding component, and a comprehensive component for assembling nuts and unloading them;

[0006] The positioning component includes a turntable rotatably connected to the worktable and multiple workstations circumferentially distributed around the turntable axis. The multiple workstations include a flat pad feeding workstation, a main body feeding workstation, a waterproof ring feeding workstation, a nut feeding workstation, and a discharge workstation, which are sequentially distributed along the edge of the turntable and correspond to the flat pad feeding component, the main body feeding component, the waterproof ring feeding component, the nut feeding component, and the integrated component, respectively. Each of the multiple workstations is provided with an outer cylinder positioned on the turntable, an inner cylinder elastically connected to the outer cylinder and for the flat pad to be fitted, and a positioning rod with one end protruding from the inner cylinder and for the main body shell to be fitted. The outer diameter of the inner cylinder matches the inner diameter of the outer cylinder, and one end of the inner cylinder is limited to the outer cylinder. The end of the main body shell for the nut connection can be partially inserted into the inner cylinder.

[0007] The flat pad is fed onto the outer wall of the inner cylinder of the flat pad feeding station by the flat pad feeding assembly, so that the turntable can move the flat pad to the main body feeding station. As the main body feeding assembly presses down on the main body shell, the inner cylinder retracts into the outer cylinder, so that the flat pad on the outer wall of the inner cylinder is pushed by the end face of the outer cylinder to the outer wall of one end of the main body shell. As the turntable continues to rotate, the main body shell containing the flat pad passes through the waterproof ring feeding station, the nut feeding station and the unloading station in sequence, and completes the installation of waterproof rings, nuts and bolts and the collection of finished products.

[0008] As a further improvement of this utility model, the outer wall of the positioning rod is provided with an alignment strip that is symmetrical about the plane containing the axis of the positioning rod and can fit against the inner wall of the main body shell.

[0009] As a further improvement of this utility model, the end of the alignment strip away from the turntable is chamfered.

[0010] As a further improvement of this utility model, the flat pad feeding assembly includes a flat pad feeding channel driven by a vertical vibrator, a flat pad feeding seat connected to one end of the flat pad feeding channel and capable of accommodating only one flat pad, a four-jaw chuck located on the other side of the flat pad feeding seat relative to the flat pad feeding channel, a flat pad manipulator for clamping the flat pad in the flat pad feeding seat to the four-jaw chuck, a flat pad feeding cylinder that moves synchronously with the flat pad manipulator, a flat pad push ring positioned on the output shaft of the flat pad feeding cylinder, and multiple feeding columns that all pass through the flat pad push ring and move synchronously with the flat pad manipulator. The diameter of the circumference of the outer wall of the multiple feeding columns matches the inner diameter of the flat pad push ring, and the diameter of the circumference of the inner wall of the multiple feeding columns is greater than the outer diameter of the inner cylinder. The flat pad, which is tightened outside the multiple feeding columns, is pushed towards the outer wall of the inner cylinder by the flat pad push ring, so that the flat pad is tightened outside the inner cylinder.

[0011] As a further improvement of this utility model, the main body feeding assembly includes a main body material channel driven by a direct vibrator, a main body feeding seat connected to the end of the main body material channel and capable of accommodating only one main body shell, a rotary cylinder located on the other side of the main body feeding seat relative to the main body material channel, two main body manipulators capable of clamping the main body shell to the rotary cylinder and the main body feeding station in sequence, and a main body monitor located on one side of the rotary cylinder for observing whether the main body shell has defects.

[0012] As a further improvement of this utility model, the waterproof ring feeding assembly includes a waterproof ring feeding channel driven by a direct vibrator, a waterproof ring feeding seat connected to the end of the waterproof ring feeding channel and capable of accommodating only one waterproof ring, a top-feeding cylinder positioned below the waterproof ring feeding seat and whose output end can penetrate into the waterproof ring feeding seat, a finger cylinder located above the waterproof ring feeding seat and used to clamp the waterproof ring, a bottom-feeding cylinder capable of pushing the waterproof ring clamped by the finger cylinder down, and a first combined driver capable of moving the finger cylinder and the bottom-feeding cylinder. By clamping the waterproof ring with the finger cylinder and moving it to the waterproof ring feeding station, the bottom-feeding cylinder can push the waterproof ring into the main body shell.

[0013] As a further improvement of this utility model, the nut feeding assembly includes a nut feeding channel driven by a vibrator, a nut feeding seat connected to the end of the nut feeding channel and capable of accommodating only one nut, a first tightening cylinder for driving the nut to rotate, two clamping feet located on both sides of the output shaft of the first tightening cylinder for clamping the nut, a second combined driver for driving the first tightening cylinder to move, an anti-rotation cylinder for limiting the rotation of the main body shell at the nut feeding station, and a top member elastically connected to the output shaft of the first tightening cylinder. Both clamping feet can elastically swing relative to the output shaft of the tightening cylinder.

[0014] As a further improvement of this utility model, the integrated component includes a nut feed channel driven by a direct vibrator, a feed channel connected to the end of the nut feed channel, a nut feed seat located at one end of the feed channel and capable of accommodating only one nut, a feed cylinder positioned at the other end of the feed channel and used to push the nut into the nut feed seat, a second tightening cylinder capable of rotating the nut feed seat, a support piece elastically connected to the nut feed seat and used to accommodate the nut, a verification station positioned on one side of the second tightening cylinder, two material transfer robots capable of successively clamping the main body shell to the support piece and the verification station, a verifier facing the verification station, a collection pipe penetrating the workbench, and a material picking robot used to clamp the waterproof connector at the verification station to the collection pipe.

[0015] As a further improvement of this utility model, it also includes a monitoring component for detecting whether the assembled waterproof connector has been unloaded, and the plurality of workstations also include a redundant workstation located between the flat pad loading workstation and the unloading workstation and corresponding to the monitoring component.

[0016] The beneficial effects of this utility model are as follows: The flat pad feeding assembly feeds the flat pad onto the outer wall of the inner cylinder at the flat pad feeding station, allowing the turntable to move the flat pad to the main body feeding station. Simultaneously, the main body feeding assembly presses down on the main body shell, causing the inner cylinder to retract into the outer cylinder, pushing the flat pad on the outer wall of the inner cylinder onto the outer wall of one end of the main body shell. As the turntable continues to rotate, the main body shell containing the flat pad sequentially passes through the waterproof ring feeding station, the nut feeding station, and the unloading station, completing the installation of the waterproof ring, nut, and bolt, and the collection of finished products. Compared to existing technologies, this design simplifies the station structure and reduces station size, effectively reducing the required installation space and saving on enterprise operating costs. With the same turntable size, it effectively increases the distance between adjacent stations, ensuring reasonable spacing between components and effectively preventing interference between components, thus facilitating maintenance and repair. Furthermore, the number of stations is reduced accordingly, as is the number of required components. It eliminates the need for flipping the main body shell, simplifying processing steps and effectively improving the assembly efficiency of the waterproof connector. Attached Figure Description

[0027] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments. Identical components are indicated by the same reference numerals.

[0028] Reference Figures 1 to 9 As shown, an automatic assembly machine for waterproof connectors in this embodiment includes a workbench 1, a positioning component 2, a flat washer feeding component 3, a main body feeding component 4, a waterproof ring feeding component 5, a nut feeding component 6, and a comprehensive component 7 for assembling nuts and unloading them. The main body shell includes an intermediate body with a hexagonal outer contour, a waterproof end and a flat washer end coaxial with the intermediate body and located on both sides of the intermediate body. The waterproof end can be used to insert the waterproof ring and is threadedly connected to the nut. The flat washer end can be threadedly connected to the nut. The outer contour dimensions of the waterproof end and the flat washer end are both smaller than the outer contour dimensions of the intermediate body.

[0029] Specific reference Figure 3As shown, the positioning component 2 includes a turntable 21 rotatably connected to the worktable 1 and multiple workstations 22 arranged circumferentially around the axis of the turntable 21. A stepper motor for driving the turntable 21 to rotate is fixedly connected below the worktable 1. There are five workstations 22, namely, flat pad loading workstation 221, main body loading workstation 222, waterproof ring loading workstation 223, nut loading workstation 224, and unloading workstation 225. Flat pad loading component 3, main body loading component 4, waterproof ring loading component 5, nut loading component 6, and integrated component 7 are distributed sequentially along the circumference of the turntable 21 and correspond to the flat pad loading workstation 221 and the main body loading workstation 222, respectively. The waterproof ring loading station 223, the nut loading station 224, and the unloading station 225 each have an outer cylinder 23, an inner cylinder 24, and a positioning rod 25. One end of the outer cylinder 23 is integrally formed into a cuboid block and fixed to the turntable 21 with bolts. The outer cylinder 23 has vertically extending perforations machined into its wall. The outer diameter of the inner cylinder 24 matches the inner diameter of the outer cylinder 23, and the outer wall of the inner cylinder 24 has threaded holes. The positioning rod 25 can be connected in two ways: first, the positioning rod 25 is coaxial with the outer cylinder 23, with one end positioned on the cuboid block, and the other end of the positioning rod 25 protruding from the outer cylinder 23. A spring is fitted onto the outside of the positioning rod 25. Then, the inner cylinder 24 is fitted onto the positioning rod 25 and inserted into the outer cylinder 23. A bolt is used to pass through the hole and screw into the threaded hole on the outer wall of the inner cylinder 24, preventing the inner cylinder 24 from detaching from the outer cylinder 23. The spring is positioned between the inner cylinder 24 and the cuboid block. Alternatively, one end of the inner cylinder 24 is closed, and the positioning rod 25 is coaxially fixed to the inner cylinder 24. One end of the positioning rod 25 protrudes from the inner cylinder 24. Then, the spring and inner cylinder 24 are sequentially installed into the outer cylinder 23. A bolt is used to pass through the hole and screw into the threaded hole on the outer wall of the inner cylinder 24, preventing the inner cylinder 24 from detaching from the outer cylinder 23. The spring is positioned between the inner cylinder 24 and the cuboid block. The connection configuration of the positioning rod 25 in the above two methods is selected according to actual needs. The diameter of rod 25 is adapted to the inner diameter of the flat pad end, and the outer diameter of the flat pad end is adapted to the inner diameter of the inner cylinder 24. The end edge of the positioning rod 25 located outside the inner cylinder 24 is chamfered. There are two structural relationships between the flat pad end and the inner cylinder 24. First, an inner ring with an inner diameter larger than the diameter of the positioning rod 25 and smaller than the diameter of the flat pad end is integrally formed on the inner wall or at the port of the inner cylinder 24. The distance between the ring and the other end of the inner cylinder 24 is less than the length of the flat pad end. Second, a convex ring for tightening the flat pad is integrally formed at the end of the flat pad end connected to the intermediate body. The outer diameter of the convex ring is between the inner diameter and the outer diameter of the port of the inner cylinder 24. The aforementioned structural design of the inner cylinder 24 varies accordingly based on the structure of the flat pad end.

[0035] In the initial state, one end of the inner cylinder 24 at all workstations 22 is located outside the outer cylinder 23 and remains stationary. The flat pad robot 34 and the flat pad feeding cylinder 35 are located directly above the flat pad feeding seat 32 and the four-jaw chuck 33, respectively. The drive shafts of the four-jaw chuck 33 are all far apart, so that the diameter of the circumference of the four support rods is larger than the diameter of the circumference of the multiple feeding columns 37.

The material handling robot 700 is located directly above the collecting pipe 70. The power is turned on and the relevant processing operations are performed. The assembly steps of the waterproof connector are as follows:

[0036] Step 1: The flat pad is transported by the vibratory feeder and flat pad feed channel 31 to the flat pad feeding seat 32. The flat pad robot 34 and the flat pad loading cylinder 35 both move downwards to their positions. The grippers of the flat pad robot 34 extend into the flat pad feeding seat 32 and clamp the flat pad. Multiple loading columns 37 penetrate the inner cavity enclosed by multiple support rods. The drive shafts of the four-jaw chuck 33 move closer together and retract to the inside of the circumference of the multiple loading columns 37, tightening the flat pad outside the multiple loading columns 37. Then, the flat pad robot 34 and the flat pad loading cylinder 35 reset, and the flat pad in the flat pad feed channel 31 enters the flat pad feeding seat 32 for the next clamping. Next, the flat pad robot 34 and the flat pad loading cylinder 35 move horizontally to their positions. Directly above the four-jaw chuck 33 and the flat pad loading station 221, the flat pad robot 34 and the flat pad loading cylinder 35 move downwards into position. The four support rods of the four-jaw chuck 33 pass through the flat pad held by the flat pad robot 34. One end of the inner cylinder 24 passes into the circumference of the multiple loading columns 37. Then, the flat pad loading cylinder 35 drives the flat pad push ring 36 to move downwards, causing the flat pad to be pushed away from the loading column 37 and retract onto the outer wall of the inner cylinder 24. The flat pad robot 34 releases the flat pad, causing it to fall onto the drive shaft of the four-jaw chuck 33. Finally, the flat pad push ring 36 resets first, and the flat pad robot 34 and the flat pad loading cylinder 35 reset later. The drive shafts of the four-jaw chuck 33 move away from each other, causing the four support rods to open the flat pad for removal by the loading column 37 next time.

[0037] In the second step, the turntable 21 rotates at a certain angle, causing the inner cylinder 24 containing the flat pad to move from the flat pad loading station 221 to the main body loading station 222. The main body shell is transported by the vibrating plate and the main body material channel 41 to the main body feeding seat 42. The rotary cylinder 43 drives the main body shell to rotate one revolution. The main body monitor 45 performs visual inspection on the main body shell on the output shaft of the rotary cylinder 43. Then, both main body robotic arms 44 move downwards and clamp the main body shell in the main body feeding seat 42 and the main body shell at the rotary cylinder 43, respectively. Then, both main body robotic arms 44 reset and move horizontally until they are directly above the rotary cylinder 43 and the main body loading station 222, respectively. At the same time, the main body shell in the main body material channel 41 enters the main body feeding seat 42 for the next clamping. Then, the two main body robotic arms 44 move downwards and move horizontally until they are directly above the rotary cylinder 43 and the main body loading station 222, respectively. At the same time, the main body shell in the main body material channel 41 enters the main body feeding seat 42 for the next clamping. Both robotic arms 44 move downwards into position. One main body shell is fitted onto the output shaft of the rotary cylinder 43. The flat pad end of the other main body shell extends into the inner cylinder 24 and presses down on the inner cylinder 24, causing the inner cylinder 24 to retract into the outer cylinder 23. The corresponding spring is compressed until the flat pad outside the inner cylinder 24 is pushed away from the inner cylinder by the end of the outer cylinder 23. The flat pad retracts to the outer wall of the flat pad end of the main body shell and is close to the connection between the intermediate body and the flat pad end. Finally, both main robotic arms 44 release the corresponding main body shells and reset. The inner cylinder 24 resets relative to the outer cylinder 23 under the action of the spring. To further explain, if the main body shell detected by the main body monitor 45 has defects, the main body shell will only be transported without assembly in subsequent processes until it is moved to the collection tube 70 for classification and collection. If the main body shell has no defects, the main body shell will be assembled and collected as usual in subsequent processes.

[0038] Third step: Turntable 21 rotates at a certain angle, causing the main body shell containing the flat pad to move from the main body loading station 222 to the waterproof ring loading station 223. The waterproof ring is transported by the vibrating plate and the waterproof ring material channel 51 to the waterproof ring feeding seat 52. The output shaft of the top cylinder 53 moves upward, lifting the waterproof ring in the waterproof ring feeding seat 52 and preventing the waterproof ring in the waterproof ring material channel 51 from entering the waterproof ring feeding seat 52. Then, the finger cylinder 54 and the unloading cylinder 55 move downward simultaneously. The two grippers of the finger cylinder 54 move to both sides of the lifted waterproof ring, and the finger cylinder 54 clamps the waterproof ring and unloads it. Cylinder 55 moves upward synchronously to its position, the output shaft of top material cylinder 53 returns to its initial state, the waterproof ring in the waterproof ring material channel 51 enters the waterproof ring feeding seat 52 for the next clamping, then finger cylinder 54 and unloading cylinder 55 move synchronously to directly above the waterproof ring loading station 223, then finger cylinder 54 and unloading cylinder 55 move downward synchronously a certain distance so that the waterproof ring is close to the top of the main body shell, then the output shaft of unloading cylinder 55 pushes the waterproof ring downward so that the waterproof ring disengages from finger cylinder 54 and enters the main body shell, finally unloading cylinder 55 and finger cylinder 54 both return to their initial state;

[0039] Step 4: Turntable 21 rotates at a certain angle, causing the main body shell containing the waterproof ring and flat washer to move from the waterproof ring feeding station 223 to the nut feeding station 224. The output shaft of the anti-rotation cylinder 66 extends towards the nut feeding station 224, causing the anti-rotation groove of the output shaft to engage with the outer wall of the main body shell. The nut is transported by the vibrating plate and the nut material channel 61 to the nut feeding seat 62. The first tightening cylinder 63 moves downward, causing the ends of the two clamping feet 64 to slide relative to the edge of the nut and clamp the outer wall of the nut. Both clamping feet 64 elastically swing relative to the output shaft of the first tightening cylinder 63 and form a figure-eight shape. The upper surface of the nut contacts the top piece 67, and the top piece 67 partially retracts into the output shaft of the first tightening cylinder 63. And the corresponding spring is compressed. Then the first tightening cylinder 63 takes the nut out of the feeding seat 62 and moves it quickly to the nut loading station 224 while the top piece 67 pushes the nut downward. At the same time, the nut in the nut channel 61 enters the nut feeding seat 62 for the next clamping. The nut contacts the top of the main body shell. Then the first tightening cylinder 63 drives the two clamping feet 64 to rotate. Under the action of the downward pushing force of the top piece 67, the nut corresponds to the thread on the outside of the end of the main body shell and is screwed on the main body shell under the rotation force of the first tightening cylinder 63. Finally, the first tightening cylinder 63 and the anti-rotation cylinder 66 return to the initial state. The nut is disengaged from the clamping feet 64. The two clamping feet 64 and the top piece 67 return to the initial state.

[0040] Step 5: Turntable 21 rotates at a certain angle, causing the main body shell containing the nut, waterproof ring, and flat washer to move from the nut loading station 224 to the unloading station 225. The nut is transported by the vibrating plate and the nut feed channel 71 to the distribution channel 72. Two transfer robots 78 move downwards synchronously and grab the waterproof connector on the nut feed seat 73 and the main body shell at the unloading station 225, respectively. Then, both transfer robots 78 move upwards and horizontally into position, respectively, and are located directly above the calibration station 77 and the nut feed seat 73. The bottom of the groove of the support 76 is flush with the bottom of the groove of the nut feed seat 73. The distribution cylinder 74 pushes the nut in the distribution channel 72 into the nut feed seat 73 and the support 76, respectively. The distribution cylinder 74 resets, and the nut in the nut feed channel 71 enters the distribution channel 72 for the next entry into the nut feed seat 73. Then, both transfer robots 78 move downwards. Once in position, the waterproof connector is fitted onto the calibration station 77 and visually inspected by the calibrator 79. The nutless main body shell presses down on the nut feed seat 73, causing the support piece 76 to move downward relative to the nut feed seat 73. The corresponding spring is compressed. Then, the second tightening cylinder 75 drives the nut feed seat 73 and the support piece 76 to rotate as a whole. The nut inside the support piece 76 rotates relative to the main body shell until the nut aligns with the external thread of the main body shell. Under the action of the spring, the support piece 76 pushes the nut upward so that the nut can be smoothly screwed onto the outside of the main body shell. The two material transfer robots 78 release the waterproof connector and the main body shell respectively and return to their initial state. The material handling robot 700 moves to the calibration station 77 and clamps the waterproof connector. According to the detection result of the calibrator 79, the robot 700 performs a corresponding horizontal displacement and moves the waterproof connector above the corresponding collection pipe 70 for release. The waterproof connector is then collected by classification through the collection pipe 70.

[0041] Step 6: Rotate turntable 21 at a certain angle so that the inner cylinder 24 without any parts is moved from the unloading station 225 to the flat pad loading station 221 and repeat the above five steps. In this way, the waterproof joint can be assembled one by one.

[0042] Compared with existing technologies, the design of positioning component 2 simplifies the structure and reduces the size of station 22, effectively reducing the required installation space and saving the company's operating costs. With the same size turntable 21, it effectively increases the distance between adjacent stations 22, and the spacing between each component is reasonable, effectively avoiding interference between components and facilitating the maintenance and repair of each component. Furthermore, the number of stations 22 is reduced accordingly, and the number of components required is reduced accordingly. It eliminates the need for flipping the main body shell as required by existing technologies, simplifies the processing steps, and effectively improves the assembly efficiency of waterproof connectors.

[0043] Compared with the existing technology, the design of adding a main body monitor 45 and a rotary cylinder 43 to the main body feeding assembly 4 can detect unqualified main body shells earlier, effectively save the use and assembly time of subsequent parts, and further improve assembly efficiency.

[0044] The design of the nut feeding assembly 6, which uses the clamp 64 to hold the nut and rotates with the output shaft of the first tightening cylinder 63, is different from the existing technology of feeding the nut first and then tightening it with the tightening cylinder. This design simplifies the assembly steps and component structure of the existing technology, effectively reduces enterprise costs and improves the assembly efficiency of the waterproof connector.

[0045] Compared to existing technologies, the design of integrated component 7 eliminates the flipping operation and combines verification and sorting collection into one, offering comprehensive functions and occupying little space, thus improving the efficiency of assembly, inspection, and sorting collection.

[0046] As one specific implementation of the improvement, there is a situation where the inner diameter of the end of the main body shell is slightly smaller than the diameter of the positioning rod 25, which can easily cause the main body shell to fail to fit onto the positioning rod 25. To solve the aforementioned problem, refer to Figure 3 As shown, the diameter of the positioning rod 25 is reduced, and an alignment strip 26 is integrally formed on the outer wall of the positioning rod, symmetrical about the plane containing the axis of the positioning rod 25 and able to fit against the inner wall of the main body shell. The end of the alignment strip 26 away from the turntable is chamfered. If the main body shell and the positioning rod 25 are not coaxial, the port of the main body shell slides relative to the chamfer of the alignment strip 26 and adjusts to a position coaxial with the positioning rod 25. If the inner diameter of the port of the main body shell is less than the maximum distance between the two alignment strips 26, a slight deformation will occur during the sliding of the port of the main body shell relative to the chamfer of the alignment strip 26, so that the port of the main body shell can be fitted onto the two alignment strips 26. This design can ensure that the main body shell is smoothly positioned on the workstation 22 and facilitate the subsequent assembly of various parts.

[0047] As one specific implementation of the improvement, the main body shell at the unloading station 225 may not be clamped and instead moves to the flat pad loading station 221. This can easily cause processing accidents and damage the corresponding components. To solve the aforementioned problem, refer to... Figures 1 to 3As shown, workstation 22 also includes a redundant workstation 226 located between the flat pad loading workstation 221 and the unloading workstation 225. A monitoring component 8 corresponding to the redundant workstation 226 is installed on the workbench 1. The detection component 8 uses visual detection to monitor whether there is a main body shell on the redundant workstation 226. If the main body shell is installed on the redundant workstation 226, each component stops operating and the controller issues an alarm so that the staff can perform maintenance in time. If the main body shell is not installed on the redundant workstation 226, each component operates normally. This design can stop and maintain in time when a problem occurs, indirectly improving assembly efficiency and safety, ensuring the safe use of each component, and indirectly reducing the company's operating costs.
