The output end of the pre-installation drive member 311 is connected to the pre-installation transmission member 312, and the pre-installation transmission member 312 is connected to the pre-installation assembly 32. The pre-installation assembly 32 includes a pre-installation member 321 and a pre-installation sliding member 322. The two ends of the pre-installation sliding member 322 are respectively connected to the pre-installation bottom plate 341 and the pre-installation top plate 342. The pre-installation sliding member 322 is adjacent to the pre-installation opening 3421. The pre-installation member 321 is slidably connected to the pre-installation sliding member 322, and is connected to the pre-installation transmission member 312. The pre-installation member 321 carries the fixed components for pre-installation. The pre-installed driving member 311 drives the pre-installed transmission member 312, and the pre-installed transmission member 312 drives the pre-installed component 32 to approach or move away from the pre-installed port 3421. The pre-installed driving member 311 is a driving motor, which is fixed to the pre-installed bottom plate 341 through a bracket. The pre-installed transmission member 312 includes a driving wheel 3121, a synchronous belt 3122, a plurality of transition wheels 3123, two driven wheels 3124 and two pre-installed transmission screws 3125. The output end of the pre-installed driving component 311 is connected to the driving wheel 3121, and the driving wheel 3121 is respectively connected to multiple transition wheels 3123 and two driven wheels 3124 through a synchronous belt 3122. The two pre-installed transmission screw rods 3125 are respectively located at the diagonals of the pre-installed base plate 341. The pre-installed screw rod 3124 is perpendicular to the pre-installed base plate 341. The two ends of the pre-installed screw rod 3124 are respectively rotatably connected to the pre-installed base plate 341 and the pre-installed top plate 342. The two driven wheels 3124 are respectively sleeved on the two pre-installed screw rods 3124. The multiple transition wheels 3123 are respectively located between the driving wheel 3121 and the two driven wheels 3124, and are respectively connected to the synchronous belt 3122 to change the direction of the synchronous belt 3122 to avoid interference with other components.In this way, driven by the pre-installed driving part 311, through the transmission of the active wheel 3121, the synchronous belt 3122, multiple transition wheels 3123 and two driven wheels 3124, the two pre-installed transmission screws 3125 can be rotated synchronously, and a pre-installed nut 3126 is sleeved on the pre-installed transmission screw 3125. The rotation of the pre-installed transmission screw 3125 is converted into a linear movement of the pre-installed nut 3126. The pre-installed nut 3126 is connected to the pre-installed component 32, so that the pre-installed component 32 can be driven to perform reciprocating linear motion between the pre-installed bottom plate 341 and the pre-installed top plate 342. The pre-installed sliding member 322 includes four pre-installed sliding rods 3221 and a pre-installed sliding plate 3222. The two ends of the four pre-installed sliding rods 3221 are respectively connected to the pre-installed bottom plate 341 and the pre-installed top plate 342. The four pre-installed sliding rods 3221 are respectively located on the inner side of the four pre-installed pillars 343. The pre-installed sliding rods 3221 are parallel to the pre-installed pillars 343. The four corners of the pre-installed sliding plate 3222 are respectively slidably connected to the four pre-installed sliding rods 3221, and the pre-installed sliding plate 3222 is connected to the pre-installed nut 3126. The pre-installed component 321 is arranged on the pre-installed slide plate 3222. The pre-installed component 321 is a frame, on which a screw bearing position 3211 for the fixed component is arranged, and the number and position of the screw bearing position 3211 are adapted to the number and position of the screw holes to be assembled in the product. When the pre-installed nut 3126 moves linearly, it drives the pre-installed slide plate 3222 to slide on the pre-installed slide bar 3221, and drives the pre-installed slide plate 3222 to move between the pre-installed bottom plate 341 and the pre-installed top plate 342. The reciprocating linear motion enables the screw bearing position 3211 to approach or move away from the pre-installation port 3421. When the screw bearing position 3211 approaches the pre-installation port 3421, the loading and transfer assembly 22 sequentially transfers the fixed components to the screw bearing position 3211, and then the screw bearing position 3211 moves away from the pre-installation port 3421. When the product is in place, the screw bearing position 3211 approaches the pre-installation port 3421 again, so that the fixed components pass through the pre-installation port 3421 and are correspondingly assembled on the product. The screw bearing position 3211 in this embodiment can adopt a slot or a rack with a hexagonal structure to facilitate the bearing of one end of the screw with a hexagonal nut. When the screw is set at the screw bearing position 3211, it is perpendicular to the pre-installation bottom plate 341.

[0047] Continue to refer to Figures 9 to 11 , Fig.11 3 is a schematic diagram of the structure of the guide mechanism in this embodiment. Furthermore, the pre-installation mechanism 3 also includes a guide assembly 33. The guide assembly 33 guides the fixed components moved by the pre-installation assembly 32. Preferably, the number of the guide assemblies 33 is four, and the four guide assemblies 33 are respectively arranged on the lower surface of the pre-installation top plate 342 and adjacent to the four sides of the pre-installation port 3421 to guide the movement of multiple fixed components.

[0048] Specifically, the guide assembly 33 includes a guide support plate 331, a first guide drive member 332, a guide slide 333, a second guide drive member 334, a third guide drive member 335 and a guide member 336. The longitudinal section of the guide support plate 331 is an "L"-shaped plate, one end of which is slidably connected to the lower surface of the pre-installed top plate 342, and the other end of the guide support plate 331 extends toward the pre-installed bottom plate 341 and is adjacent to the pre-installed port 3421. The first guide drive member 332 is provided on the pre-installed top plate 342, and its output end is connected to the guide support plate 331. The first guide drive member 332 drives the guide support plate 331 to move in a direction parallel to the pre-installed top plate 342. In this embodiment, the first guide drive member 332 is a cylinder. The guide slide 333 is slidably connected to one end of the guide support plate 333 extending toward the pre-installed bottom plate 341, and the guide slide 333 is adjacent to the pre-installed port 3421. The second guide drive 334 is arranged on the guide support plate 331, and its output end is connected to the guide slide 333. The second guide drive 334 drives the guide slide 333 to move linearly along the direction perpendicular to the pre-installed top plate 342. The second guide drive 334 in this embodiment can be a cylinder. The third guide drive 335 is arranged on the side wall of the guide slide 333 near the pre-installed port 3421, and its output end is connected to the guide member 336. The guide member 336 includes two guide blocks 3361, which are respectively slidably connected to the guide slide 333, and the opposite side of the two guide blocks 3361 is provided with a semicircular groove, and the semicircular grooves of the two guide blocks 3361 form a circular channel, which is adapted to the fixed component. The third guide drive 335 drives the two guide blocks 3361 to move closer to each other and away from each other. The third guide drive 335 in this embodiment can be a bidirectional cylinder. In this way, the first guide driving member 332 and the second guide driving member 334 are driven in cooperation to realize the guide member 336 approaching or moving away from the pre-installation port 3421, and the opening and closing of the guide member 336 is controlled by the third guide driving member 335. In specific applications, the number of the third guide driving member 335 and the guide member 336 is adapted to the screw bearing position 3221, so as to guide the pre-installed multiple fixing components passing through the same side of the pre-installation port 3421. When the loading and transferring assembly 22 transfers the fixed component through the pre-loading port 3421, the third guide drive 335 drives the guide 336 to open and keep it open, and the first guide drive 332 drives the guide 336 to approach the pre-loading port 3421, so that the opened guide 336 is opposite to the pre-loading port 3421. At this time, the second guide drive 334 remains undriven. In this way, after the fixed component moved by the loading and transferring assembly 22 passes through the pre-loading port 3421, it directly passes through the open guide 336 to be loaded to the screw bearing position 3211, so that the subsequent guide 336 can quickly perform clamping and guiding.At the same time, the pre-installed drive 311 can drive the screw bearing position 3211 to rise a certain distance, or to a position close to the pre-installed port 3421, to receive the fixed parts loaded by the loading and transfer assembly 22. The specific lifting height of the screw bearing position 3211 can be determined according to the length of the fixed parts, thereby realizing the receiving and carrying of fixed parts of different lengths. Then, the pre-installed drive 311 drives the screw bearing position 3211 to drop again and move away from the pre-installed port 3421. At this time, the third guide drive 335 can drive the guide member 336 to clamp, and a circular channel is formed through the semicircular grooves of the two guide blocks 3361 to guide the fixed parts. Of course, the guide member 336 can also wait until the screw bearing position 3211 drops to its position before clamping and guiding. Then, after the slide plate carrying the product is in place, the second guide drive 334 drives the clamped guide 336 to lift and abut against the lower surface of the slide plate carrying the product, so that the circular channel of the guide 336 is directly opposite to the through hole position of the slide plate carrying the product, so that the lifting assembly of the fixed component can be accurately guided. After that, the pre-installation drive 311 drives the screw bearing position 3211 to lift again, driving the fixed component to lift along the guide direction of the guide 336 and approach the pre-installation port 3421, so that the threaded end of the fixed component passes through the pre-installation port 3421, accurately passes through the through hole of the slide plate carrying the product, and then passes through the through hole of the lower end plate of the product. Afterwards, the screw bearing position 3211 continues to be lifted until the fixing component passes through the upper end plate of the product. At the same time, the third guide drive 335 drives the guide member 336 to open, and the first guide drive 332 and the second guide drive 334 cooperate to drive the guide member 336 away from the pre-installation port 3421 to avoid the continued movement of the screw bearing position 3211.

[0049] Continue to refer to Figure 3 and Fig.12 , Fig.12 It is a structural diagram of the press-fitting assembly and the locking assembly in this embodiment. Furthermore, the press-fitting mechanism 4 includes a press-fitting drive assembly 41 and a press-fitting assembly 42. The output end of the press-fitting drive assembly 41 is connected to the press-fitting assembly 42. The press-fitting drive assembly 41 drives the press-fitting assembly 42 to move, and the press-fitting assembly 42 presses the product after the fixed components are assembled. Preferably, the press-fitting mechanism 4 also includes a locking assembly 43. The locking assembly 43 receives the locking component transferred by the feeding transfer assembly 22, and locks the fixed components assembled on the product.

[0050] Specifically, the press-fit drive assembly 41 includes a press-fit drive member 411, a press-fit transmission member 412 and a press-fit guide member 413. The press-fit drive member 411 is arranged in the carrier 12. Specifically, the press-fit drive member 411 is arranged on the lower plate 122 through a bracket, and its output end is connected to the press-fit transmission member 412. The press-fit transmission member 412 is composed of a driving wheel, a synchronous belt, a driven wheel, a press-fit screw rod 4121 and a press-fit wire plate 4122. The two ends of the press-fit screw rod 4121 are rotatably connected to the upper plate 121 and the lower plate 122 of the carrier 12 through a bearing seat, respectively, and the press-fit screw rod 4121 is perpendicular to the pre-installed bottom plate 341. The press-fit wire plate 4122 is sleeved on the press-fit screw rod 4121, and the driven wheel is sleeved on the end of the press-fit screw rod 4121. The output end of the press-fit drive 411 is connected to the driving wheel, and the driving wheel is connected to the driven wheel through a synchronous belt. In this way, the press-fit drive 411 drives the driving wheel, which can sequentially drive the synchronous belt, the driven wheel and the press-fit screw 4121 to rotate, thereby driving the press-fit wire plate 4122 to move linearly along the press-fit screw 4121. The press-fit guide 413 includes two press-fit guide rods 4131, which are respectively vertically penetrated through the upper plate 121 and form a sliding connection with the upper plate 121 through a linear bearing. The two press-fit guide rods 4131 are respectively connected to the press-fit wire plate 4122, and the press-fit wire plate 4122 moves linearly, driving the two press-fit guide rods 4131 to move linearly. There are two groups of press-fitting drive components 41, and the two groups of press-fitting drive components 41 are respectively arranged in two carriers 12, so that a support guide structure composed of four press-fitting guide rods 4131 can be formed, and the press-fitting component 42 is arranged at the upper end of the four press-fitting guide rods 4131. When the four press-fitting guide rods 4131 move linearly, the press-fitting component 42 can be driven to approach or move away from the pre-installed port 3421. The press-fitting component 42 includes a press-fitting platform 421 and a press-fitting sensor 422. The four corners of the press-fitting platform 421 are respectively connected to the upper ends of the four press-fitting guide rods 4131, and the press-fitting platform 421 is parallel to the pre-installed bottom plate 341. The press-fitting sensor 422 is arranged on the lower surface of the press-fitting platform 421. A screw position 4211 is provided in the middle part of the press-fitting platform 421, and the number and position of the screw position 4211 are consistent with the number and position of the fixed parts assembled on the product. The screw position 4211 in this embodiment is in the shape of a through hole. Preferably, a locking groove 4212 is further provided in the middle of the press-fitting platform 421, and the screw position 4211 is provided on the bottom wall of the locking groove 4122. Such a groove structure arrangement can conveniently leave space for the locking operation of the locking assembly 43. The press-fitting platform 421 moves downward and presses on the product, and the threaded end of the fixed component assembled on the product passes through the screw position 4211. At this time, the pressure sensing component 422 senses the pressure of the press-fitting platform 421 on the product. When the pressure value reaches a predetermined press-fitting value, the press-fitting platform 421 stops pressing downward and keeps the pressure constant.Then, the loading and transferring assembly 22 sequentially transfers the flat washers, spring washers and nuts loaded by the locking component loading assembly 23 to the threaded end of the fixed component, and then the locking assembly 43 locks the nut so that the fixed component is fixed on the product. The locking assembly 43 in this embodiment includes two groups, and the two locking assemblies 43 are respectively arranged on the upper surface of the press-fitting table 421 in opposite numbers. Each locking assembly 43 includes a locking drive 431 and a locking member 432. The locking drive 431 is arranged on the upper surface of the press-fitting table 421, and its output end is connected to the locking member 432. The locking drive 431 drives the locking member 432 to perform linear movement in the three-degree-of-freedom directions of the XYZ axis, respectively, so that the locking member 432 can lock the nut at the threaded end of the fixed component. The locking drive 431 in this embodiment can adopt an XYZ three-degree-of-freedom linear module, and the locking member 432 can adopt an electric screwdriver. Of course, the linear module of the X-axis of the locking drive member 431 can also be replaced by a belt transmission method, which is not limited here.

[0051] The overall operation process of the assembly and fixing device in this embodiment is as follows: when the product is stacked at the previous station, the transfer mechanism 5 transfers the fixed bearing mechanism 1 and docks with the previous stacking station, and then the loading and transferring assembly 22 loads the fixed component to the screw bearing position 3211 of the pre-installation mechanism 3. Then, when the stacked product is transferred between the pre-installation mechanism 3 and the press-fitting mechanism 4, the press-fitting drive assembly 41 first drives the press-fitting assembly 42 to press the product down and keep the pressure constant, and then the screw bearing position 3211 assembles the fixed component into the product. Then, the loading and transferring assembly 22 loads the flat gasket, spring gasket and nut to the threaded end of the fixed component in turn, and the locking assembly 43 locks the nut.

[0052] The above is only an embodiment of the present invention and is not intended to limit the present invention. For those skilled in the art, the present invention may have various modifications and variations. Any modification, equivalent substitution, improvement, etc. made within the spirit and principle of the present invention should be included in the scope of the claims of the present invention.
