[0055] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, not the entire structure.

They are used only for ease of description and simplification of operation, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. In addition, the terms "first" and "second" are only used for distinction in description and have no special meaning.

[0059] This embodiment provides a screw fastening device that enables automatic screw assembly, improving assembly efficiency, reducing worker workload, and removing defective products to prevent them from flowing into the next process, thus improving product assembly efficiency and quality. Optionally, in one possible embodiment, this screw fastening device is used for assembling screws on a trip unit.

[0060] Specifically, such as Figure 1 and Figure 2 As shown, the screw fastening equipment includes a conveyor line 100, a material distribution mechanism 200, a transfer mechanism 300, a screw fastening mechanism 400, a detection mechanism 500, and a material kicking mechanism 600.

[0061] The conveyor line 100, along the conveying direction, is sequentially equipped with a material sorting area, a screw fastening area, an inspection area, and a ejection area. Semi-finished products 10 to be assembled are fed upstream of the material sorting area, sorted, and then conveyed to the screw fastening area. In the screw fastening area, the semi-finished products 10 are assembled with screws to form finished products 20. These are then conveyed to the inspection area for inspection. After inspection, they are conveyed to the ejection area. In the ejection area, unqualified finished products 20 are ejected from the conveyor line 100, while qualified finished products 20 continue to be conveyed by the conveyor line 100, finally exiting downstream of the conveyor line 100.

[0062] The material distribution mechanism 200 is used to fix at least one semi-finished product 10 in the material distribution area. That is, the material distribution mechanism 200 is used to quantitatively divide and fix a preset number of semi-finished products 10, the preset number being the same as the number of semi-finished products 10 that the screw-driving mechanism 400 can assemble simultaneously. Optionally, in one possible embodiment, the screw-driving mechanism 400 can assemble two semi-finished products 10 at a time, and correspondingly, the material distribution mechanism 200 is used to fix two semi-finished products 10 in preparation for assembly.

[0063] The transfer mechanism 300 is used to simultaneously pick up the semi-finished product 10 in the material distribution area and the finished product 20 with screws fastened in the screw fastening area, and simultaneously transport the semi-finished product 10 to the screw fastening area and the finished product 20 to the inspection area. During the transportation process, the transfer mechanism 300 will push the finished product 20 in the inspection area into the kicking area.

[0064] The screw-driving mechanism 400 is used to screw screws into the assembly holes of the semi-finished product 10 located in the screw fastening area to form the finished product 20.

[0065] The testing agency 500 is used to test whether the screws on the finished product 20 in the testing area are properly assembled.

[0066] The kicking mechanism 600 is used to kick out unqualified finished products 20 from the kicking area and out of the conveyor line 100.

[0067] To facilitate understanding, the working process of this screw fastening equipment will be briefly introduced, taking the separation and fixing of two semi-finished products 10 in the material distribution area as an example:

[0068] Start the screw fastening equipment, and place the semi-finished product 10 of the screw to be assembled at the entrance end of the conveyor line 100 by manual or robotic arm. Under the conveying of the conveyor line 100, the semi-finished product 10 will be conveyed to the sorting area.

[0069] Once the semi-finished products 10 arrive at the material distribution area, the two semi-finished products 10 will be fixed in the material distribution area under the action of the material distribution mechanism 200;

[0070] The transfer mechanism 300 is controlled to operate, pick up two semi-finished products 10 in the material distribution area, and transport the two semi-finished products 10 to the screw fastening area. After the transport is completed, the transfer mechanism 300 returns to the initial position. Since there are no semi-finished products 10 in the screw fastening area, the inspection area and the kicking area when the first operation is started, the transfer mechanism 300 does not transport the finished products 20 in the screw fastening area when the first operation is started.

[0071] The screw-driving mechanism 400 assembles the required number of screws into both semi-finished products 10 in the screw fastening area. After the screws are assembled, the material distribution mechanism 200 simultaneously completes the material distribution of the two products.

[0072] Control the transfer mechanism 300 to work, simultaneously pick up two semi-finished products 10 in the material distribution area and two finished products 20 on the screw fastening area, and simultaneously transport the two semi-finished products 10 to the screw fastening area and the two finished products 20 to the inspection area. After the transport is completed, the transfer mechanism 300 returns to the initial position.

[0073] The inspection mechanism 500 inspects whether the screw fastening on the two finished products 20 is qualified. During this process, the inspection rhythm of the inspection mechanism 500 is controlled to be the same as the rhythm of the screw fastening mechanism 400 and the material distribution mechanism 200, that is, the inspection mechanism 500, the screw fastening mechanism 400 and the material distribution mechanism 200 complete one work at the same time.

[0074] After the inspection is completed, the transfer mechanism 300 is controlled to work, simultaneously picking up two semi-finished products 10 in the material distribution area and two finished products 20 in the screw fastening area, and simultaneously conveying the two semi-finished products 10 to the screw fastening area and the two finished products 20 to the inspection area. During the conveying process, the transfer mechanism 300 will also push the finished products 20 that have been inspected to the kicking area. After the conveying is completed, the transfer mechanism 300 returns to the initial position.

[0075] The above-mentioned processes of material sorting, screwing, and inspection are repeated according to the production rhythm. Unqualified finished products 20 entering the kicking area will be removed from the conveyor line 100 by the kicking mechanism 600 and can then be collected. Qualified finished products 20 will continue to be conveyed by the conveyor line 100 and discharged from the outlet of the conveyor line 100 to be conveyed to the next process.

[0076] This screw fastening equipment enables automatic screw assembly, improving assembly efficiency and reducing worker workload. By incorporating a ejector mechanism 600, defective finished products 20 can be promptly removed to prevent them from flowing into the next process, thus improving assembly efficiency and quality.

[0077] Furthermore, each operation of the transfer mechanism 300 can transport the semi-finished product 10 in the material distribution area to the screw fastening area, the finished product 20 in the screw fastening area to the inspection area, and the inspected finished product 20 in the inspection area to the kicking area. Compared with the related technologies that complete the above work through three separate handling mechanisms, it greatly reduces the use of parts, lowers equipment costs, simplifies the control process, and is more conducive to controlling the production cycle.

[0078] Furthermore, such as Figure 2 and Figure 3 As shown, the transfer mechanism 300 includes a first drive member 310, a first support 320, a clamping member 330, and a second drive member 340. The output end of the first drive member 310 is connected to the first support 320, and the first drive member 310 drives the first support 320 to switch between a first working position and a second working position along the conveying direction of the conveyor line 100. The clamping member 330 includes a main body 331 and multiple clamps 332. The main body 331 is slidably connected to the first support 320 along a conveying direction perpendicular to the conveyor line 100, and multiple clamps 332 are provided on the side of the main body 331 closest to the conveyor line 100. The second driving member 340 is disposed on the first bracket 320. The output end of the second driving member 340 is connected to the main body 331. The second driving member 340 is used to drive the main body 331 to drive multiple chucks 332 to simultaneously clamp the semi-finished product 10 in the material distribution area and the finished product 20 in the screw fastening area when the first bracket 320 is in the first working position, and to drive the main body 331 to drive the chucks 332 to separate from the semi-finished product 10 in the screw fastening area and the finished product 20 in the detection area when the first bracket 320 is in the second working position.

[0079] The working principle of the transfer mechanism 300 is as follows:

[0080] When the first driving member 310 drives the first support 320 to the first working position, the second driving member 340 can drive the main body 331 to simultaneously grip the semi-finished product 10 in the material distribution area and the finished product 20 in the screw fastening area. Then, the first driving member 310 drives the first support 320 to the second working position. During this process, the clamping member 330 pushes the finished product 20 in the inspection area to the ejection area. When the first driving member 310 drives the first support 320 to the second working position, the semi-finished product 10 on the clamp 332 is transferred to the screw fastening area, and the finished product 20 is transferred to the inspection area. Then, the second driving member 340 drives the main body 331 to separate the clamp 332 from the semi-finished product 10 in the screw fastening area and the finished product 20 in the inspection area, completing the transfer operation. Finally, the first driving member 310 drives the first support 320 back to the first working position, awaiting the next transfer.

[0081] The transfer mechanism 300 has a simple structure. By controlling the operation of the first drive component 310 and the second drive component 340, the transfer of the semi-finished product 10 and the finished product 20 can be completed, which is easy to control.

[0082] Understandably, the first drive component 310 is optional, but not limited to, a cylinder.

[0083] Understandably, the second drive unit 340 is optional, but not limited to, a cylinder.

[0084] Optionally, see [link to relevant documentation] Figure 3 In one possible embodiment, the main body 331 is provided with a plurality of clamping arms 3321 on the side near the conveyor line 100, and two adjacent clamping arms 3321 form a chuck 332. The two clamping arms 3321 are used to clamp the semi-finished product 10 or the finished product 20. The structure is simple, will not damage the semi-finished product 10 or the finished product 20, and also facilitates the separation of the chuck 332 from the semi-finished product 10 or the finished product 20.

[0085] It is worth noting that the number of clamping arms 3321 can be set according to the material distribution situation of the material distribution mechanism 200.

[0086] For example, see [link to previous article] Figure 2 and Figure 3 In this embodiment, multiple clamps 332 can simultaneously clamp two semi-finished products 10 and two finished products 20. Since there are gaps between the two semi-finished products 10 in the material distribution area and the two finished products 20 in the screw fastening area, this embodiment provides eight clamping arms 3321, which form seven clamps 332, and four clamps 332 are used for operation.

[0087] Further, see also Figure 1 and Figure 3 The transfer mechanism 300 is mounted on the worktable 700, which has a slide rail 350 extending along the conveying direction of the conveyor line 100. A slider 321 is mounted on the first support 320 and slidably connected to the slide rail 350. The cooperation between the slide rail 350 and the slider 321 guides the movement between the first and second working positions, improving the smoothness and stability of the first support 320's movement.

[0088] Optionally, see [link to relevant documentation] Figure 1 In one possible embodiment, the conveyor line 100, the material distribution mechanism 200, the screw-driving mechanism 400, the detection mechanism 500, the transfer mechanism 300, and the kicking mechanism 600 are all arranged on the workbench 700.

[0089] Furthermore, such as Figure 4As shown, along the conveying direction perpendicular to the conveyor line 100, a first baffle 110 and a second baffle 120 are respectively provided on opposite sides of the conveyor line 100. It can be understood that the first baffle 110 and the second baffle 120 are used to stop the semi-finished product 10 or the finished product 20, so as to prevent the semi-finished product 10 and the finished product 20 from falling off during the conveying process.

[0090] A first positioning mechanism 800 is provided on the first baffle 110 within the screw fastening area. The first positioning mechanism 800 is used to press the semi-finished product 10 against the second baffle 120. By setting the first positioning mechanism 800, the semi-finished product 10 can be fixed in the screw fastening area without stopping the conveyor line 100, so as to ensure the reliability of the assembly screws.

[0091] A second positioning mechanism 900 is provided on the first baffle 110 within the inspection area. The second positioning mechanism 900 is used to press the finished product 20 against the second baffle 120. By providing the second positioning mechanism 900, the finished product 20 can be fixed in the inspection area without stopping the conveyor line 100, so that the inspection mechanism 500 can perform inspection.

[0092] Optionally, in one possible embodiment, each first positioning mechanism 800 is used to fix one semi-finished product 10. That is, if the screw-driving mechanism 400 can assemble one semi-finished product 10 at the same time, then one first positioning mechanism 800 is set accordingly; if the screw-driving mechanism 400 can assemble two semi-finished products 10 at the same time, then two first positioning mechanisms 800 are set accordingly.

[0093] It is understandable that if each second positioning mechanism 900 is used to fix one finished product 20, then the number of second positioning mechanisms 900 is the same as that of the first positioning mechanism 800.

[0094] Optionally, such as Figure 5 As shown, in one possible embodiment, the first positioning mechanism 800 includes a mounting bracket 810, a positioning block 820, and an elastic element 830. The mounting bracket 810 is disposed on the side of the first baffle 110 opposite to the second baffle 120, and the positioning block 820 slides through the first baffle 110. The first end of the positioning block 820 faces the second baffle 120, and the second end faces the mounting bracket 810. The elastic element 830 is disposed between the mounting bracket 810 and the positioning block 820, and is used to push the first end of the positioning block 820 to press the semi-finished product 10 against the second baffle 120. This first positioning mechanism 800 has a simple structure, and by providing the elastic element 830, the positioning block 820 can always apply a pushing force to the semi-finished product 10, resulting in a better positioning effect.

[0095] Optionally, see [link to relevant documentation] Figure 5 A through hole 111 can be provided on the first baffle 110 so that the positioning block 820 can slide through the through hole 111.

[0096] Optionally, the cross-section of the positioning block 820 may be cylindrical, rectangular, etc., which can be set according to actual needs, and the present application does not make specific limitations.

[0097] Optionally, continue to refer to Figure 5 , multiple elastic members 830 may be provided to increase the thrust of the positioning block 820 on the semi-finished product 10, thereby improving the positioning reliability of the first positioning mechanism 800.

[0098] Optionally, in a possible embodiment, one end of the elastic member 830 abuts against the mounting bracket 810, and the other end is inserted into the slot 823 of the positioning block 820.

[0099] Optionally, continue to refer to Figure 5 , the mounting bracket 810 is in a "U" shape.

[0100] Optionally, in a possible embodiment, the structure of the second positioning mechanism 900 is the same as that of the first positioning mechanism 800. With this setting, it is convenient for processing and helps reduce the R & D cost. Of course, in other possible embodiments, the structure of the second positioning mechanism 900 may also be different from that of the first positioning mechanism 800, which can be set according to actual needs, and the present application does not make specific limitations.

[0101] Further, continue to refer to Figure 5 , on the first end of the positioning block 820, a guiding inclined surface 821 is provided on the side of the positioning block 820 close to the material distribution area. The guiding inclined surface 821 is used to guide the semi-finished product 10 into the space between the positioning block 820 and the second retaining wall 120. By providing the guiding inclined surface 821, the difficulty of the transfer mechanism 300 in transporting the semi-finished product 10 to the first positioning mechanism 800 is reduced.

[0102] Further, continue to refer to Figure 5 , two limiting ears 822 are provided at the second end of the positioning block 820. The two limiting ears 822 can abut against the first retaining wall 110 to limit the sliding stroke of the positioning block 820, and further limit the distance between the first end of the positioning block 820 and the second retaining wall 120, so as to ensure that the semi-finished product 10 can more easily enter the space between the first end of the positioning block 820 and the second retaining wall 120.

[0103] Further, as shown in Figure 1 and Figure 6 , a pressing mechanism 1000 is provided upstream of the material distribution mechanism 200. The pressing mechanism 1000 is used to press the semi-finished product 10 so that the two shells of the semi-finished product 10 are buckled in place, facilitating the subsequent assembly of screws.

[0104] Optionally, continue to refer to Figure 6The pressing mechanism 1000 includes a second support 1100, a third drive member 1200 mounted on the second support 1100, and a pressing head 1300 connected to the output end of the third drive member 1200. The pressing head 1300 is located above the conveyor line 100, and the third drive member 1200 drives the pressing head 1300 to descend and press the semi-finished product 10. This pressing mechanism 1000 has a simple structure and is easy to control.

[0105] Understandably, the third drive unit 1200 is optional but not limited to a cylinder.

[0106] Optionally, the second bracket 1100 can be fixed to one side of the conveyor line 100. It can also be fixed to the workbench 700, depending on actual needs. This application does not impose any specific limitations.

[0107] Further, see also Figure 1 Above the conveyor line 100, upstream of the material distribution area, a first limiting cover 130 is provided to limit the displacement of the semi-finished product 10 along the height direction. Since the conveyor line 100 may be in a continuous conveying state during the material distribution process of the material distribution mechanism 200, by setting the first limiting cover 130, it is possible to prevent the semi-finished products 10 from tilting due to stacking.

[0108] Further, see also Figure 1 Above the conveyor line 100, upstream of the ejector area, a second limiting cover 140 is provided. The second limiting cover 140 is used to limit the displacement of the finished product 20 along the height direction. By setting the second limiting cover 140, it is possible to prevent the finished products 20 from tilting due to stacking.

[0109] Furthermore, such as Figure 7 As shown, the material distribution mechanism 200 can distribute two semi-finished products 10 at a time. Specifically, the material distribution mechanism 200 includes a first baffle assembly 210, a second baffle assembly 220, a third baffle assembly 230, and a fourth baffle assembly 240 arranged sequentially at intervals along the conveying direction. The first baffle assembly 210, the second baffle assembly 220, and the third baffle assembly 230 all have a stop state that blocks the semi-finished product 10 and a clearance state that allows the semi-finished product 10 to pass, while the fourth baffle assembly 240 always maintains the stop state that blocks the semi-finished product 10.

[0110] The working principle of the material distribution mechanism 200 is as follows:

[0111] For ease of understanding, each pair of adjacent semi-finished products 10 is grouped together, and the two semi-finished products 10 in the same group are the first semi-finished product and the second semi-finished product in the order of material arrival from the material distribution area.

[0112] When the first semi-finished product passes the first baffle assembly 210, the first baffle assembly 210 moves to the stop state to stop the second semi-finished product, while the second baffle assembly 220 and the third baffle assembly 230 move to the avoidance state to release the first semi-finished product;

[0113] When the first semi-finished product is stopped by the fourth material blocking component 240, the third material blocking component 230 and the second material blocking component 220 move to the stop state at the same time, and then the first material blocking component 210 moves to the avoidance state to release the second semi-finished product;

[0114] When the second semi-finished product passes the first stop assembly 210, the first stop assembly 210 moves to the stop state to stop the next group of first semi-finished products. At the same time, the second stop assembly 220 moves to the avoidance state to release the second semi-finished product.

[0115] When the second semi-finished product is stopped by the third baffle assembly 230, the second baffle assembly 220 moves to the stop state, thus completing the separation of the first and second semi-finished products.

[0116] Optionally, in one possible embodiment, the first stop assembly 210 includes a first telescopic drive member and a first stop head connected to the output end of the first telescopic drive member. The first telescopic drive member is used to drive the first stop head to extend to stop the semi-finished product 10 and to drive the first stop head to retract to release the semi-finished product 10. The second stop assembly 220 includes a second telescopic drive member and a second stop head connected to the output end of the second telescopic drive member. The second telescopic drive member is used to drive the second stop head to extend to stop the semi-finished product 10 and to drive the second stop head to retract to release the semi-finished product 10. The third stop assembly 230 includes a third telescopic drive member and a third stop head connected to the output end of the third telescopic drive member. The third telescopic drive member is used to drive the third stop head to extend to stop the semi-finished product 10 and to drive the third stop head to retract to release the semi-finished product 10. The fourth stop assembly 240 includes a fourth telescopic drive member and a fourth stop head connected to the output end of the fourth telescopic drive member. The fourth telescopic drive member always drives the fourth stop head to maintain the state of stopping the semi-finished product 10.

[0117] In this embodiment, the working principle of the material distribution mechanism 200 is as follows:

[0118] When the first semi-finished product passes the first baffle assembly 210, the first telescopic drive component drives the first baffle head to extend and stop the second semi-finished product. At the same time, the second telescopic drive component drives the second baffle head to retract, and the third telescopic drive component drives the third baffle head to retract.

[0119] When the first semi-finished product moves to the fourth stop, the third telescopic drive drives the third stop to extend, the second telescopic drive drives the second stop to extend, and then the first telescopic drive drives the first stop to retract.

[0120] When the second semi-finished product moves to the second stop head, the first telescopic drive component drives the first stop head to extend and stop the next set of first semi-finished products. The second telescopic drive component drives the second stop head to retract. When the second semi-finished product 10 moves to the third stop head, the second telescopic drive component drives the second stop head to extend and the first telescopic drive component drives the first stop head to retract. In this way, the separation of the first semi-finished product and the second semi-finished product is completed.

[0121] Optionally, the first telescopic drive, the second telescopic drive, the third telescopic drive, and the fourth telescopic drive can all be cylinders.

[0122] Optionally, the first stop head can be a stop bar, a stop block, etc.

[0125] Optionally, the fourth stop head can be a stop bar, a stop block, etc.

[0126] Furthermore, such as Figure 8 As shown, the kicking mechanism 600 includes a fifth blocking component 610, a sixth blocking component 620, and a kicking component 630 arranged sequentially at intervals along the conveying direction. The fifth blocking component 610 and the sixth blocking component 620 both have a blocking state to stop the finished product 20 and a yielding state to allow the finished product 20 to pass. The kicking component 630 has a kicking state to kick the finished product 20 out of the conveyor line 100 and a yielding state to allow the finished product 20 to pass.

[0127] The working principle of the 600 ejector mechanism is as follows:

[0128] For ease of understanding, each pair of adjacent finished products 20 is grouped together, and the two finished products 20 in the same group are the first finished product and the second finished product in the order of material arrival in the kicking area.

[0129] When the testing agency 500 detects that the first finished product and / or the second finished product are unqualified, the sixth stop assembly 620 moves to the stop state to stop the first finished product;

[0130] After the first finished product is stopped by the sixth stop assembly 620, the fifth stop assembly 610 moves to the stop state to stop the second finished product, while the sixth stop assembly 620 moves to the avoidance state to release the first finished product.

[0131] When the first finished product moves to the kicking component 630, if the first finished product is not qualified, the kicking component 630 moves to the kicking state to kick the first finished product out of the conveyor line 100; if the first finished product is qualified, the kicking component 630 moves to the avoidance state to release the first finished product.

[0132] Then the fifth stop assembly 610 moves to the avoidance state to release the second finished product. When the second finished product moves to the kicking assembly 630, if the second finished product is not qualified, the kicking assembly 630 moves to the kicking state to kick the second finished product out of the conveyor line 100. If the second finished product is qualified, the kicking assembly 630 moves to the avoidance state to release the second finished product.

[0133] Optionally, in one possible embodiment, the fifth stop assembly 610 includes a fifth telescopic drive member and a fifth stop head connected to the output end of the fifth telescopic drive member. The fifth telescopic drive member is used to drive the fifth stop head to extend to stop the finished product 20 and to drive the fifth stop head to retract to release the finished product 20. The sixth stop assembly 620 includes a sixth telescopic drive member and a sixth stop head connected to the output end of the sixth telescopic drive member. The sixth telescopic drive member is used to drive the sixth stop head to extend to stop the finished product 20 and to drive the sixth stop head to retract to release the finished product 20. The kicking assembly 630 includes a seventh telescopic drive member and a kicking head. The output end of the seventh telescopic drive member is connected to the kicking head and is used to drive the kicking head to extend to kick the finished product 20 out of the conveyor line 100 and to drive the kicking head to retract to release the finished product 20.

[0134] Optionally, the fifth, sixth, and seventh telescopic drive components can all be cylinders.

[0135] Optionally, the fifth stop head can be a stop bar, a stop block, etc.

[0136] Optionally, the sixth stop can be a stop bar, a stop block, etc.

[0137] Alternatively, the kick head can be a kick rod, a kick block, etc.

[0138] Optionally, see [link to relevant documentation] Figure 1 A defective product collection box 150 corresponding to the kicking assembly 630 is provided on one side of the conveyor line 100. The opening of the defective product collection box 150 faces the conveyor line 100. The kicking assembly 630 is used to kick the unqualified finished products 20 from the conveyor line 100 into the defective product collection box 150 for centralized collection.

[0139] Furthermore, such as Figure 9As shown, in one possible embodiment, the detection mechanism 500 includes a third support 510 and a CCD detection module 520. The CCD detection module 520 is mounted on the third support 510 and located above the detection area. The CCD detection module 520 generally includes an imaging system, a signal processing system, and a control system. The imaging system acquires an image of the finished product 20 in the detection area, the signal processing system processes the image and transmits it to the control system, and the control system analyzes and outputs the results. It is worth noting that the structure and working principle of the CCD detection module 520 are existing technologies, and its specific structure is not the subject of this application; therefore, its specific structure will not be described in detail here.

[0140] Furthermore, such as Figure 1 and Figure 10 As shown, the screw-driving mechanism 400 includes a screw feeding unit 410, a fourth bracket 420, a fifth bracket 430, a screw-tightening unit 440, and a fourth driving member 450. The fifth bracket 430 is slidably connected to the fourth bracket 420 in a vertical direction. The screw-tightening unit 440 is mounted on the fifth bracket 430, and each screw-tightening unit 440 corresponds to a mounting hole on the semi-finished product 10. The fourth driving member 450 is mounted on the fourth bracket 420, and its output end is connected to the fifth bracket 430. It drives the fifth bracket 430 to lower the screw-tightening unit 440, allowing the screw-tightening unit 440 to screw the screws into their corresponding mounting holes. The screw feeding unit 410 feeds screws one by one to the screw-tightening unit 440.

[0141] The screw-driving mechanism 400 has a simple structure and can automatically fasten screws, resulting in high assembly efficiency.

[0142] The working principle of the screw-driving mechanism 400 is as follows:

[0143] Before the semi-finished product 10 reaches the screw fastening area, the screw feeding unit 410 supplies one screw to the screw tightening unit 440 respectively;

[0144] After the semi-finished product 10 reaches the screw fastening area, the fourth drive component 450 drives the fifth bracket 430 to drive the screw tightening unit 440 to descend to the preset height;

[0145] Next, start the screw tightening unit 440 to screw the screw into the assembly hole according to the preset torque;

[0146] Finally, the fourth drive unit 450 drives the fifth bracket 430 to raise the screw tightening unit 440 to the initial position, and the screw feeding unit 410 feeds a screw to the screw tightening unit 440 again.
