[0002] In the process of assembling workpiece accessories, taking the assembly of glass accessories as an example, it is necessary for manual installation of various accessories on the tooling base plate in advance, and then the glass is adsorbed and transferred to the tooling base plate by the robot. During the glass adsorption and transfer, it is also necessary to position it through the positioning tool; the glass transferred to the tooling base plate is installed with the cooperation of the robot and the action mechanism arranged on the tooling base plate. The above assembly process is a single-station operation, that is, when the robot is assembling and processing, the operator needs to wait for the robot to be assembled before continuing to install the accessories of the next tooling base plate. The overall assembly efficiency is low, which limits production capacity. Summary of the invention

[0009] In order to explain the technical content, achieved objectives and effects of the present invention in detail, the following is an explanation in combination with the implementation modes and the accompanying drawings.

[0010] Taking the glass accessory assembly as an example, the traditional method requires manual assembly of the accessories in sequence, and then the glass is transferred by a robot and the accessories are installed. During the robot operation, the operator needs to wait for the robot to complete the processing before continuing to install the accessories of the next tooling base plate 211.

[0011] Please refer to Figures 1 to 11 A double-layer automated connection tooling includes a handling and assembly mechanism 1, a conveying mechanism, and an accessory installation tooling 21; the conveying mechanism includes an assembly area 26 and a feeding area 27; two sets of accessory installation tooling 21 are respectively connected to the conveying mechanism by transmission, and in the vertical direction, the two sets of accessory installation tooling 21 are staggered; the handling and assembly mechanism 1 is located at the feeding end of the conveying mechanism and can be arranged opposite to the feeding area 27.

[0012] It can be understood that the beneficial effect of the present invention is that through the cooperation of two sets of accessory installation tools 21 and the conveying mechanism that are staggered in the vertical direction, it is possible to carry out upstream and downstream processes simultaneously, that is, the processing process at the handling and assembly mechanism 1 and the manual assembly process on one side of the assembly area 26 are synchronized, thereby improving the overall rhythm and improving the assembly efficiency.

[0013] In some embodiments, the conveying mechanism includes a slide rail base 24, an upper slide rail 22, a lower slide rail 23, a lifting slider 25, and a driving mechanism. A sunken space is provided inside the slide rail base 24. The upper slide rail 22 is disposed on the upper side of the slide rail base 24, and the lower slide rail 23 is disposed in the sunken space. The two sets of accessory installation toolings 21 are respectively an upper tooling slidably connected to the upper slide rail 22 and a lower tooling slidably connected to the lower slide rail 23. A lifting slider 25 is provided between the upper tooling and the upper slide rail. The driving mechanism is in transmission connection with the upper tooling and the lower tooling. As can be seen from the above description, through the arrangement that the upper slide rail 22 and the lower slide rail 23 on the slide rail base 24 are respectively located on the upper side of the slide rail base 24 and in the sunken space, the staggered setting of the two sets of accessory installation toolings 21 is realized. Further, by setting the lifting slider 25 of the upper slide rail 22, it is ensured that there is sufficient passing space for the accessory installation tooling 21 located on the lower slide rail 23. The upper tooling and the lower tooling slide respectively through the connected driving mechanism, and the driving mechanism is disposed in the sunken space.

[0014] In some embodiments, a positioning assembly is further included. The positioning assembly includes a horizontal positioning assembly and a vertical positioning assembly. The horizontal positioning assembly and the vertical positioning assembly are disposed on the conveying mechanism, and the horizontal positioning assembly and the vertical positioning assembly are respectively connected to the corresponding accessory installation tooling to limit its displacement in the conveying direction of the conveying mechanism and the direction perpendicular to the conveying direction of the conveying mechanism. As can be seen from the above, through the positioning cooperation of the horizontal positioning assembly and the vertical positioning assembly, the positioning setting of the accessory installation tooling after moving to the assembly area can be realized, ensuring the accuracy of subsequent processing operations.

[0015] In some embodiments, the accessory installation tooling 21 includes a tooling bottom plate 211 and an accessory installation mechanism. The accessory installation mechanism is disposed on the upper end surface of the tooling bottom plate 211. The accessory installation mechanism is used for cooperative operation with the handling and assembly mechanism 1. As can be seen from the above description, through the arrangement of the accessory installation mechanism on the upper end surface of the tooling bottom plate 211, the interference during the movement between the upper accessory installation tooling 21 and the lower accessory installation tooling 21 can be avoided. At the same time, compared with the traditional single-layer tooling, the unilateral arrangement of the accessory installation mechanism can reduce the overall thickness of the tooling, which is more suitable for the implementation of synchronous operation of the upper and lower layers.

[0016] In some embodiments, the accessory installation tooling 21 further includes a profiling main body 213 and a vacuum system. The profiling main body 213 is used to cooperate and fix with the workpiece to be assembled. Both the profiling main body 213 and the vacuum system are arranged on the upper end surface of the tooling bottom plate 211, and the vacuum system is connected to the accessory installation mechanism. It can be seen from the above description that the profiling main body 213 is used to cooperate and fix with the workpiece to be assembled, and the vacuum system is used as the driving power to drive the accessory installation mechanism to perform the assembly operation. The arrangement of the above structure on the upper end surface of the tooling bottom plate 211 can ensure that the lower end surface of the tooling bottom plate 211 and the space corresponding to the lower end surface are not occupied, and the compact arrangement of the upper and lower layer toolings 2 can be ensured.

[0017] In some embodiments, the vacuum system includes a shunt pipeline. The profiling main body 213 is hollow inside, and the shunt pipeline is arranged inside the profiling main body 213. It can be seen from the above description that by arranging the shunt pipeline of the vacuum system inside the profiling main body 213, the space occupied by the shunt pipeline on the tooling bottom plate 211 can be reduced, and the size reduction design of the accessory installation tooling 21 can be ensured.

[0018] In some embodiments, the accessory installation mechanism includes a stud installation structure 214. The stud installation structure 214 includes a first connection plate 2141, a first driving cylinder, and a stud installation seat 2142. A first relief opening 2143 is provided at a position on the tooling bottom plate 211 opposite to the stud installation structure 214. The first connection plate 2141 is connected to the edge of the first relief opening 2143. The first driving cylinder is connected to the first connection plate 2141, and a stud installation seat 2142 is provided on the transmission end of the first driving cylinder. It can be seen from the above description that the stud installation structure 214 can be used for installing studs on the workpiece to be assembled. During installation, the operator in the assembly area 26 places the studs on the stud installation seat 2142. After the accessory installation tooling 21 is transferred to the handling and assembly mechanism 1, the handling and assembly mechanism 1 fixes the workpiece to be assembled. Then, the first driving cylinder drives the stud installation seat 2142 to move towards the stud installation position of the workpiece to be assembled and bond the studs. Through the design of the first relief opening 2143, it can be ensured that the first driving cylinder has enough driving stroke.

[0019] In some embodiments, the handling and assembling mechanism 1 includes a mounting bracket 13, a pressing block assembly 11, and a locking bracket 12. The pressing block assembly 11 and the locking bracket 12 are both disposed on one side of the mounting bracket 13 close to the accessory installation tooling 21. The pressing block assembly 11 is used to press the workpiece to be assembled against the accessory installation tooling 21. The accessory installation mechanism includes a locking structure 217, which includes a second driving cylinder, a docking seat 2171, and a locking pin 2172. The docking seat 2171 is provided with a docking groove that is inserted and matched with the locking bracket 12. The locking bracket 12 and the docking groove are both provided with communicating sockets. The second driving cylinder drives the locking pin 2172 to insert into the socket. As can be seen from the above description, the handling and assembling mechanism 1 uses the mounting bracket 13 as the installation position, integrating the pressing block assembly 11 and the locking bracket 12. Among them, the pressing block assembly 11 is used to press and fix the workpiece to be assembled on the accessory installation tooling 21. The locking bracket 12 cooperates with the locking structure 217. After the locking bracket 12 is inserted into the docking groove of the docking seat 2171, the second driving cylinder drives the locking pin 2172 to pass through the locking bracket 12 and the docking seat 2171 at the same time, so that the two are fixedly matched, thereby preventing the entire handling and assembling mechanism 1 from pressing against the workpiece to be assembled and being affected by reverse impact, which affects the movement accuracy of the handling and assembling mechanism 1 itself.

[0020] In some embodiments, it further includes a workpiece positioning tooling 3. The workpiece positioning tooling 3 is disposed on one side of the handling and assembling mechanism 1. The workpiece positioning tooling 3 includes a machine table 31, a support member 32, a lateral positioning member 33, and a vertical positioning member 34. The machine table 31 is provided with a support member 32 for supporting the workpiece. The lateral positioning member 33 includes a lateral positioning seat 331, and the vertical positioning member 34 includes a vertical positioning seat 341. In the length direction of the machine table 31, at least one lateral positioning seat 331 is provided at each end of the machine table 31, and every two oppositely arranged lateral positioning seats 331 can move towards each other. In the width direction of the machine table 31, at least one vertical positioning seat 341 is provided at each end of the machine table 31, and every two oppositely arranged lateral positioning seats 331 can move towards each other. As can be seen from the above description, the workpiece to be assembled is positioned before being transferred to the accessory installation tooling 21 through the workpiece positioning tooling 3, and then can be positioned and clamped by the handling and assembling mechanism 1 and transferred to the accessory installation tooling 21, without the need to adjust the position of the workpiece to be assembled on the accessory installation tooling 21 again. Specifically, after the workpiece to be assembled is transferred to the workpiece positioning tooling 3, it is supported by the support member 32, and then the lateral positioning seat 331 and the vertical positioning seat 341 clamp and position the workpiece to be assembled in four directions in turn.

[0021] An assembly method applied to the above double-layer automatic connection tooling: S1: The handling and assembling mechanism 1 transports the workpiece to be assembled to the accessory installation tooling 21 located in the blanking area 27. S2: The accessory installation tooling 21 in the blanking area 27 enters the assembly area 26 through the conveying mechanism, and accessories are assembled on the accessory installation tooling 21 located in the assembly area 26; S3: After the accessory installation tooling 21 is assembled, it enters the blanking area 27 through the conveying mechanism, and the handling and assembly mechanism 1 performs assembly operations on the accessory installation tooling 21; S4: After the handling and assembly mechanism 1 assembles the workpiece to be assembled, it discharges the material, and at the same time, S1 is repeatedly executed.

[0022] As can be seen from the above description, through the above assembly method, the synchronous operation of the assembly area 26 and the blanking area 27 can be realized, improving the situation in the application of traditional single-layer tooling where operators are idle and waiting for the handling and assembly mechanism 1 to complete the assembly operation, which slows down the production rhythm.

[0023] Please refer to Figures 1 to 11 , Embodiment 1: A double-layer automated connection tooling, including a handling and assembly mechanism 1 and an upper and lower layer tooling 2. The upper and lower layer tooling 2 includes an accessory installation tooling 21, a sliding base 24, a driving mechanism, an upper slide rail 22, and a lower slide rail 23. The sliding base 24, the upper slide rail 22, the lower slide rail 23, and the driving mechanism are combined as a conveying mechanism, and an assembly area 26 and a blanking area 27 are provided at both ends of the conveying mechanism. The accessory installation tooling 21 includes an upper layer tooling and a lower layer tooling. The upper slide rail 22 and the lower slide rail 23 are parallel and arranged vertically on the sliding base 24. Specifically, the upper slide rail 22 is provided on the upper side of the sliding base 24, a sunken space is provided inside the sliding base 24, the lower slide rail 23 is provided in the sunken space and moves on the upper slide rail 22. An upper layer tooling is arranged to move on the upper slide rail 22, and a lower layer tooling is arranged to move on the lower slide rail 23; a lifting slider 25 is provided at the bottom of the upper layer tooling to increase the interval between the upper layer tooling and the lower layer tooling and avoid the sliding interference of the lower layer tooling; the transmission end of the driving mechanism is connected to the upper layer tooling and the lower layer tooling; the handling and assembly mechanism 1 is arranged in the blanking area 27 of the conveying mechanism. In this embodiment, the handling and assembly mechanism 1 is a manipulator fixture tooling. Correspondingly, a guardrail 4 is provided at the assembly area 26. During the operation, the accessory installation tooling 21 transferred by the upper slide rail 22 is first assembled with accessories by the operator in the assembly area 26, while the accessory installation tooling 21 transferred by the lower slide rail 23 has been previously assembled in the assembly area 26 and transferred to the manipulator fixture tooling for processing. The accessory installation tooling 21 on both the upper slide rail 22 and the lower slide rail 23 can be synchronously assembled by the manipulator fixture tooling or the operator in the assembly area 26, greatly improving the overall assembly efficiency.

[0024] Such as Figure 5As shown, specifically, in order to ensure that the accessory installation tooling 21 can move on the upper slide rail 22 and the lower slide rail 23 without interference, a thinning treatment of the accessory installation tooling 21 is adopted. Among them, the accessory installation tooling 21 includes a tooling base plate 211 and an accessory installation mechanism. The accessory installation mechanism includes a profiling main body 213, a vacuum system, a stud installation structure 214, and a sucker lifting structure 215. The above-mentioned accessory installation mechanisms are all installed on the upper end surface of the tooling base plate 211, so that the lower end surface of the tooling base plate 211 is flat and has sufficient clearance space to meet the movement of another accessory installation tooling 21 on the lower slide rail 23. In addition, a fiber optic display box 219 for preventing leakage during accessory installation is also provided in the middle of the tooling base plate 211.

[0025] According to the processing requirements, the accessory installation mechanism further includes a pad installation component 216 for installing pads of the workpiece to be assembled.

[0026] As Figure 10 and Figure 11 As shown, in the transfer and positioning of the accessory installation tooling 21, a positioning component for positioning the accessory installation tooling 21 in the assembly area 26 is designed. The positioning component includes a horizontal positioning component and a vertical positioning component. The horizontal positioning component is used to limit the movement of the accessory installation tooling 21 in the length direction of the transfer mechanism. The horizontal positioning component includes a positioning socket 29, a driving cylinder arranged between the tooling base plate 211 and the sliding base 24, and a horizontal tooling positioning pin 220 arranged on the lower side of the tooling base plate 211. After the tooling base plate 211 moves in place, the driving cylinder drives the positioning socket 29 to lift and insert with the horizontal tooling positioning pin 220, thereby restricting the movement of the tooling base plate 211 in the length direction of the transfer mechanism.

[0027] The vertical tooling positioning component includes a vertical tooling positioning pin 218, a positioning cylinder, and a tooling positioning seat 28. Tooling positioning seats 28 are provided on the upper slide rail 22 and the lower slide rail 23 in the assembly area 26. The vertical tooling positioning pin 218 and the positioning cylinder are arranged on the tooling base plate 211 of the accessory installation tooling 21. After the tooling base plate 211 moves to the assembly area 26, it is driven by the positioning cylinder connected to the vertical tooling positioning pin 218, so that the vertical tooling positioning pin 218 is inserted into the tooling positioning seat 28 to achieve tooling positioning. Through the positioning cooperation of the horizontal tooling positioning component and the vertical tooling positioning component, the positioning setting after the movement of the accessory installation tooling 21 is realized.

[0028] The profiling main body 213 is arranged in a frame structure on the tooling base plate 211, and a plurality of sucker lifting structures 215 are arranged in an array in the middle thereof. A space for installing a vacuum system is formed by surrounding among the plurality of sucker lifting structures 215. The pad mounting assemblies 216 are arranged at intervals along the edge of the profiling main body 213, and the stud mounting structure 214 is also arranged inside the profiling main body 213. Specifically, the stud mounting structure 214 includes a first connecting plate 2141, a first driving cylinder, and a stud mounting seat 2142. A first relief opening 2143 is provided at a position of the tooling base plate 211 opposite to the stud mounting structure 214. The first connecting plate 2141 is connected to the edge of the first relief opening 2143. The first driving cylinder is connected to the first connecting plate 2141, and a stud mounting seat 2142 is provided on the transmission end of the first driving cylinder. Compared with the traditional stud mounting structure 214 that needs to set an adjustable space and requires the stud mounting structure 214 to be sunk to the lower end surface of the tooling base plate 211, the stud mounting structure 214 in this solution can be directly arranged on the upper end surface of the tooling base plate 211 to avoid occupying the space of the lower end surface of the tooling base plate 211 due to the sunk design.

[0029] The vacuum system includes a plurality of shunt pipelines connected to the above-mentioned pad mounting assemblies 216, sucker lifting structures 215, and stud mounting structures 214. The above-mentioned structures can be actuated by using the vacuum system as a driving source. Specifically, the profiling main body 213 is designed with a hollow interior, and the shunt pipelines are arranged inside the profiling main body 213, greatly reducing the occupation of the upper end surface of the tooling base plate 211.

[0030] Embodiment 2: The difference between this embodiment and Embodiment 1 is that as Figure 2 and Figure 3 shown, the manipulator fixture tooling includes a mounting bracket 13, a pressing block assembly 11, a locking bracket 12, a sucker assembly 15, and a positioning pin 14. The pressing block assembly 11, the locking bracket 12, and the sucker assembly 15 are all arranged on the side of the mounting bracket 13 close to the upper and lower layer tooling 2; the pressing block assembly 11 is used to press the workpiece to be assembled onto the upper and lower layer tooling 2. Specifically, the pressing block assembly 11 faces the edge strip manually assembled on the accessory mounting tooling 21, and the workpiece to be assembled and the edge strip are pressed and fitted by the pressing block assembly 11; the sucker assembly 15 is used to adsorb the workpiece to be assembled.

[0031] As Figure 5As shown, the accessory installation mechanism further includes a locking structure 217 and a positioning pin seat 212. The locking bracket 12 is used to cooperate with the locking structure 217. The locking structure 217 includes a second driving cylinder, a docking seat 2171 and a locking pin 2172. The docking seat 2171 is provided with a docking groove for plugging and cooperating with the locking bracket 12. The locking bracket 12 and the docking groove are both provided with communicating sockets, and the second driving cylinder drives the locking pin 2172 to insert into the socket. The positioning pin seat 212 cooperates with the positioning pin 14 to achieve positioning during the operation of the manipulator fixture tooling.

[0032] After the accessory installation tooling 21 is transferred to the blanking area 27, the manipulator fixture tooling moves downward to make the workpiece to be assembled close to the tooling bottom plate 211. Then, the suction cup lifting structure 215 on the tooling bottom plate 211 lifts and adsorbs the workpiece to be assembled. Then, the pressing block assembly 11 of the manipulator fixture tooling acts, and the locking bracket 12 of the manipulator fixture tooling cooperates with the locking structure 217 to be fixed, so as to avoid the influence of the downward pressure impact on the movement accuracy of the manipulator fixture tooling.

[0033] Embodiment Three: The difference between this embodiment and Embodiment One is that as Figure 4 shown, it further includes a workpiece positioning tooling 3. The workpiece positioning tooling 3 is arranged on one side of the manipulator fixture tooling. The workpiece positioning tooling 3 includes a machine table 31, a support member 32, a lateral positioning member 33 and a vertical positioning member 34. The machine table 31 is provided with a support member 32 for supporting the workpiece; the lateral positioning member 33 and the vertical positioning member 34 are respectively arranged in the length direction and the width direction of the machine table 31; the lateral positioning member 33 includes at least two opposite lateral positioning seats 331 and a third driving cylinder, and the third driving cylinder drives the lateral positioning seats 331 to move in the length direction of the machine table 31; the vertical positioning member 34 includes at least two opposite vertical positioning seats 341 and a fourth driving cylinder, and the fourth driving cylinder drives the vertical positioning seats 341 to move in the width direction of the machine table 31. The lateral positioning seats 331 and the vertical positioning seats 341 are both provided with rollers 35, and the rollers 35 abut against the edge of the workpiece to be assembled.

[0034] During processing, the workpiece to be assembled is first transferred to the workpiece positioning tooling 3 for clamping and positioning. The workpiece to be assembled is supported by the support member 32, and then clamped and positioned by the lateral positioning seats 331 on the left and right sides of the machine table 31 and the vertical positioning seats 341 on the upper and lower sides of the machine table 31. Finally, the workpiece to be assembled is positioned, and then adsorbed and transferred by the manipulator fixture tooling, so as to avoid the need for secondary positioning of the workpiece to be assembled on the accessory installation tooling 21.

[0035] Embodiment Four: An assembly method applied to the double-layer automatic connection tooling in any one of Embodiments One to Four: S0: The operator in the assembly area 26 pre-assembles the accessories on the accessory installation tooling. S1: The handling and assembly mechanism 1 transports the workpiece to be assembled to the first set of accessory installation tooling 21 located in the blanking area 27. S2: The first set of accessory installation tooling 21 in the blanking area 27 enters the assembly area 26 through the transfer mechanism. In the assembly area 26, the operator assembles the accessories on the accessory installation tooling 21. At the same time, the handling and assembly mechanism 1 transports the workpiece to be assembled to the second set of accessory installation tooling 21 located in the blanking area 27. S3: After the first set of accessory installation tooling 21 is assembled, it enters the blanking area 27 through the transfer mechanism, and the second set of accessory installation tooling 21 enters the assembly area 26 through the transfer mechanism. The handling and assembly mechanism 1 performs the assembly operation on the first set of accessory installation tooling 21. The operator in the assembly area 26 starts to assemble the accessories on the second set of accessory installation tooling 21. S4: After the workpiece to be assembled is assembled by the handling and assembly mechanism 1, it is unloaded, and at the same time, S1 is repeatedly executed.

[0036] Working principle: The workpiece to be assembled is first transferred to the workpiece positioning tooling 3 for clamping and positioning. The lateral positioning member 33 and the vertical positioning member 34 are used for clamping and positioning, and then it is adsorbed and transferred by the manipulator fixture tooling.

[0037] Then, at the upper and lower layer tooling 2, the operator in the assembly area 26 assembles the side strip, the cushion block, and the nail column onto the corresponding profiling main body 213, the cushion block installation component 216, and the nail column installation structure 214 of the accessory installation tooling 21. Then, the accessory installation tooling 21 is transferred to the blanking area 27 through the upper layer slide rail 22 or the lower layer slide rail 23. Then, the manipulator fixture tooling moves down and cooperates with the positioning pin seat 212 and the locking structure 217 of the accessory installation tooling 21, and the suction cup lifting structure 215 lifts and adsorbs and transfers the workpiece to be assembled. After that, the pressing block assembly 11, the cushion block installation component 216, the nail column installation structure 214, etc. act synchronously to realize the installation of the side strip, the cushion block, and the nail column of the workpiece to be assembled. Then, the assembled workpiece is transferred by the manipulator fixture tooling.

[0038] When the manipulator fixture tooling performs the assembly operation on an accessory installation tooling 21, another accessory installation tooling 21 is transferred to the assembly area 26 through the upper layer slide rail 22 or the lower layer slide rail 23 for accessory installation. The processing of the manipulator fixture tooling and the manual assembly are carried out synchronously.

[0039] In summary, the double-layer automated connection tooling provided by the present invention, through the cooperation of two sets of accessory installation toolings arranged with vertical misalignment and the conveying mechanism, can achieve synchronous operation of upstream and downstream processes, that is, the processing process at the handling and assembly mechanism and the manual assembly process on one side of the assembly area, improve the overall beat, and improve the assembly efficiency; through the arrangement that the upper slide rail and the lower slide rail on the slide rail base are located on the upper side and the sunken space of the slide rail base respectively, the misalignment setting of the two sets of accessory installation toolings is realized, and further, by setting the elevation slider of the upper slide rail, it is ensured that the accessory installation tooling located on the lower slide rail has sufficient passing space; after the conveying mechanism transfers the accessory installation tooling to the assembly area, through the cooperation of the positioning cylinder and the tooling positioning pin, the tooling positioning pin is inserted into the tooling positioning seat on the conveying mechanism for tooling positioning; through the arrangement of the accessory installation mechanism on the upper end face of the tooling base plate, the interference during the movement between the upper accessory installation tooling and the lower accessory installation tooling can be avoided; at the same time, compared with the traditional single-layer tooling, the single-side arrangement of the accessory installation mechanism can reduce the overall thickness of the tooling and is more suitable for the development of synchronous operation of the upper and lower layers; the profiling main body is used to cooperate and fix with the workpiece to be assembled, and the accessory installation mechanism is driven by the vacuum system as the driving power to perform the assembly operation; the above structure arranged on the upper end face of the tooling base plate can ensure that the lower end face of the tooling base plate and the space corresponding to the lower end face are not occupied, and the compact arrangement of the upper and lower layer toolings can be ensured; by arranging the shunt pipeline of the vacuum system inside the profiling main body, the space occupied by the shunt pipeline and the tooling base plate can be reduced, and the size reduction design of the accessory installation tooling can be ensured; the stud installation structure can be used for the installation of studs on the workpiece to be assembled. During installation, the operator in the assembly area places the studs on the stud installation seat. After the accessory installation tooling is transferred to the handling and assembly mechanism, the handling and assembly mechanism fixes the workpiece to be assembled. Then, the first driving cylinder drives the stud installation seat to move towards the stud installation position of the workpiece to be assembled and bond the studs; through the design of the first relief opening, it is ensured that the first driving cylinder has sufficient driving stroke; the sucker lifting structure arranged in an array on the tooling base plate can reduce the installation space occupied by the tooling base plate compared with the traditional I-shaped integrated driven sucker, ensure that other components such as the vacuum system have sufficient installation space, and further reduce the installation layout of the lower end face of the tooling base plate, ensure the thinning layout of the accessory installation tooling, and make it suitable for the transfer of the upper slide rail and the lower slide rail; the handling and assembly mechanism sets the installation bracket as the installation position, which integrates the pressing block assembly and the locking bracket. The pressing block assembly is used to press and fix the workpiece to be assembled on the accessory installation tooling, and the locking bracket, through cooperation with the locking structure, after the locking bracket is inserted into the docking groove of the docking seat, the second driving cylinder drives the locking pin to pass through the locking bracket and the docking seat at the same time, so that the two are fixedly matched, thereby avoiding the overall handling and assembly mechanism from pressing against the workpiece to be assembled and being affected by the reverse impact, which affects the movement accuracy of the handling and assembly mechanism itself;The workpiece to be assembled is transferred to the attachment installation tooling for positioning through the workpiece positioning tooling, and then can be positioned and clamped by the manipulator fixture tooling and transferred to the attachment installation tooling, without the need to adjust the position of the workpiece to be assembled on the attachment installation tooling again; the feeding area and the assembly area can be separated through the guardrail design to ensure processing safety.
