[0032] This invention proposes a screw fastening device aimed at improving fastening efficiency.

[0033] Reference Figure 1 , Figure 2 In one embodiment of the present invention, the screw fastening device includes a conveying assembly 100, a side-pushing assembly 200, a side-blocking structure 300, a first telescopic assembly 410, a second telescopic assembly 420, a first driving assembly 430, a fastening assembly 500, and a control assembly. The conveying assembly 100 is used to convey the device 101 to be fastened along a first direction; in this embodiment, the first direction is... Figure 1As shown in the left-right direction, the conveying assembly 100 can convey the device 101 to be locked from left to right. The conveying assembly 100 can be configured to include a frame, conveyor belt, conveyor rollers, etc., and the device 101 to be locked can be an electronic device such as a speaker. The side push assembly 200 is disposed on one side of the conveying assembly 100 along the first direction. For example, the side push assembly 200 can be disposed on the front side of the conveying assembly 100, and the side push assembly 200 is used to push the device 101 to be locked on the conveying assembly 100. At least a portion of the side blocking structure 300 is disposed on the other side of the conveying assembly 100 along the first direction. For example, at least a portion of the side blocking structure 300 can be disposed on the rear side of the conveying assembly 100 and block the device 101 to be locked. Thus, the side blocking structure 300 and the side push assembly 200 cooperate to achieve the front-back positioning of the device 101 to be locked, that is, the side push assembly 200 and the at least a portion of the side blocking structure 300 are disposed on opposite sides of the conveying assembly 100. The control components can be configured to include timing control circuits such as PLCs (Programmable Logic Controllers) in the prior art.

[0034] Please refer to the above as well. Figure 3 The first telescopic assembly 410 includes a first telescopic body 411 and a first telescopic drive body 412 connected to each other. The first telescopic drive body 412 is used to drive the first telescopic body 411 to extend and retract along a second direction, and the first telescopic body 411 is positioned above the conveying assembly 100 when extended. In this embodiment, the second direction is... Figure 1 The front-to-back direction is shown. The first telescopic drive body 412 can be configured as a cylinder, and the first telescopic body 411 can be configured as a plate connected to the cylinder rod of the cylinder; of course, the first telescopic drive body 412 can be configured as the cylinder seat of the cylinder, and the first telescopic body 411 can be configured as connected to the cylinder rod of the cylinder; this embodiment does not impose any limitations on this.

[0035] Please refer to the above as well. Figure 3 The second telescopic assembly 420 includes a second telescopic body 421 and a second telescopic drive body 422 connected to each other. The second telescopic drive body 422 is used to drive the second telescopic body 421 to extend and retract along the second direction, and the second telescopic body 421 is located above the conveying assembly 100 when it extends. The second telescopic drive body 422 can be configured as a cylinder, and the second telescopic body 421 can be configured as a plate connected to the cylinder rod of the cylinder. Of course, the second telescopic drive body 422 can be configured as a cylinder seat of the cylinder, and the second telescopic body 421 can be configured as a plate connected to the cylinder rod of the cylinder. This embodiment does not limit this.

[0036] In this embodiment, the first telescopic body 411 and the second telescopic body 421 are spaced apart along the first direction. After the first telescopic body 411 and the second telescopic body 421 extend above the conveying assembly 100, the locking device 101 can be accommodated in the space formed by the two.

[0037] The first drive assembly 430 drives the second telescopic drive body 422 to move along the first direction, thereby adjusting the distance between the second telescopic body 421 and the first telescopic body 411 until the second telescopic body 421 and the first telescopic body 411 abut against the two ends of the fastening device 101 along the first direction, thereby positioning the fastening device 101 in the first direction. The fastening assembly 500 is used to fasten screws onto the fastening device 101, for example, after the fastening device 101 is positioned. The fastening assembly 500 can be moved using existing methods such as a robotic arm, and this embodiment does not limit this. The control assembly controls the conveying assembly 100, the side-pushing assembly 200, the first telescopic assembly 410, the second telescopic assembly 420, the first drive assembly 430, and the fastening assembly 500 respectively, thereby enabling the setting of the timing of positioning, screw fastening, loosening, and conveying of the fastening device 101.

[0038] In this embodiment, the first telescopic drive body 412 first drives the first telescopic body 411 to extend above the conveying assembly 100. When the device to be locked 101 is conveyed to the position of the locking screw on the conveying assembly 100, the device to be locked 101 is blocked by the first telescopic body 411 on the conveying assembly 100. The side push assembly 200 pushes the device to be locked 101 along the second direction until the device to be locked 101 is blocked by the side blocking structure 300, and the device to be locked 101 is positioned in the second direction. After the second telescopic drive body 422 drives the second telescopic body 421 to extend above the conveying assembly 100, the first drive assembly 430 drives the second telescopic drive body 422 to move along the first direction until the second telescopic body 421... The locking assembly 500 engages the screw-locking device 101, achieving first-direction positioning of the device 101. After the device 101 is positioned in the first and second directions, the locking assembly 500 tightens the screws on the device 101. After the locking assembly 500 completes the tightening, the first telescopic body 411, the second telescopic body 421, and the side-push assembly 200 retract relative to the conveying assembly 100, and the conveying assembly 100 transports the screw-locked device 101. The control assembly controls the conveying assembly 100, the side-push assembly 200, the first telescopic assembly 410, the second telescopic assembly 420, the first drive assembly 430, and the locking assembly 500, which can improve the positioning of the device 101 and the efficiency of the screw-locking action. Compared with the method of operators using screw fastening components to fasten screws, the screw fastening device in this embodiment can not only position the device to be fastened 101 through the side push component 200, the side stop structure 300, the first telescopic body 411 and the second telescopic body 421, thereby improving the positioning stability of the device to be fastened 101 during the fastening process and reducing the positional error of the fastening; but also can improve the fastening efficiency by setting the timing of the positioning, screw fastening, loosening and conveying of the device to be fastened 101 through the control component.

[0039] As an optional implementation method, refer to Figure 1 , Figure 2 The side baffle structure 300 includes a first side baffle 310 and a second side baffle 320, which are respectively disposed on opposite sides of the conveying assembly 100. (Refer to...) Figure 2The first side baffle 310, the conveying assembly 100, and the second side baffle 320 form a receiving space 301, which accommodates the device to be locked 101. A side-pushing assembly 200 can be disposed on the first side baffle 310, with the second side baffle 320 and the side-pushing assembly 200 respectively disposed on opposite sides of the conveying assembly 100 in the second direction. In this embodiment, when the device to be locked 101 enters the receiving space 301 formed by the first side baffle 310, the conveying assembly 100, and the second side baffle 320, the first side baffle 310 and the second side baffle 320 block the device to be locked 101 in the second direction, initially adjusting its position. Further positioning in the second direction is achieved through the side-pushing assembly 200 and the side-blocking structure 300, improving the positioning efficiency of the device to be locked 101 in the second direction.

[0040] As a further optional implementation, when the conveying assembly 100 conveys the device to be locked 101 in a left-to-right direction, in order to facilitate the device to be locked 101 entering the receiving space 301 formed by the first side baffle 310, the conveying assembly 100, and the second side baffle 320, refer to Figure 1 or Figure 3 The left ends of the first side baffle 310 and the second side baffle 320 are inclined outwards. In this embodiment, the left ends of the first side baffle 310 and the second side baffle 320 form a flared structure, which improves the convenience and efficiency of the device to be locked 101 entering the receiving space 301.

[0041] As an optional implementation method, refer to Figure 3 , Figure 4 The first side baffle 310 is provided with a first through hole 311 and a second through hole 312, which are spaced apart along the first direction. The side push assembly 200 includes a first side push block 210 and a second side push block 220. The first side push block 210 passes through the first through hole 311 and abuts against the screw fastening device 101, and the second side push block 220 passes through the second through hole 312 and abuts against the screw fastening device 101. The cooperation of the first side push block 210 passing through the first through hole 311 and the second side push block 220 passing through the second through hole 312 can improve the overall structural compactness of the screw fastening device and limit and guide the first side push block 210 and the second side push block 220, thereby improving the moving efficiency of the first side push block 210 and the second side push block 220.

[0042] As an optional implementation method, refer to Figure 1 , Figure 3 , Figure 4The first side pusher 210 has an elongated end face facing the conveying assembly 100 that extends along a third direction, and the second side pusher 220 has an elongated end face facing the conveying assembly 100 that extends along a third direction, which is... Figure 1 The vertical direction is shown in the figure. In this embodiment, the first side pusher 210 and the second side pusher 220 push the device 101 to be locked in the second direction and position it in the second direction. At this time, there is a certain squeezing force between the first side pusher 210, the second side pusher 220 and the device 101 to be locked; at the same time, the first telescopic body 411 and the second telescopic body 421 are used for positioning in the first direction. Since the end face of the first side pusher 210 facing the conveying component 100 is elongated and extends along the third direction, and the end face of the second side pusher 220 facing the conveying component 100 is elongated and extends along the third direction, the dimensions of the end faces of the first side pusher 210 and the second side pusher 220 facing the conveying component 100 in the first direction are relatively small. The resistance to the device 101 moving in the first direction when pushed by the first side pusher 210 and the second side pusher 220 is relatively small, which improves the positioning efficiency of the device 101 in the first direction.

[0043] As a further optional implementation, when the first side push block 210 is released from the locking device 101, at least a portion of the first side push block 210 is accommodated within the first through hole 311, thereby utilizing the space of the first through hole 311 to accommodate at least a portion of the first side push block 210, improving the structural compactness of the screw fastening device. Similarly, when the second side push block 220 is released from the locking device 101, at least a portion of the second side push block 220 is accommodated within the second through hole 312, thereby utilizing the space of the second through hole 312 to accommodate at least a portion of the first side push block 210, further improving the structural compactness of the screw fastening device.

[0044] As an optional implementation method, refer to Figure 3 The screw fastening device can also be configured to include a first side-push drive body 230 and a second side-push drive body 240. The first side-push drive body 230 is connected to a first side-push block 210, and the second side-push drive body 240 is connected to a second side-push block 220. The first side-push drive body 230 can be configured as a first side-push cylinder, with its cylinder rod fixedly connected to the first side-push block 210. The second side-push drive body 240 can be configured as a second side-push cylinder, with its cylinder rod fixedly connected to the second side-push block 220. The first side-push cylinder can include at least two cylinder rods arranged along a third direction. The second side-push cylinder can also include at least two cylinder rods arranged along a third direction. (Refer to...) Figure 2If the side of the device to be fastened 101 is set as an inclined surface, when the screw is fastened by the fastening assembly 500 from above, the force of fastening the screw will be transferred to the first side push block 210 and the second side push block 220; at least two cylinder rods are arranged along a third direction, which can improve the structural strength of the cylinder rod assembly against the third-direction impact force, thereby improving the service life of the cylinder rod assembly, the first side push drive body 230, the second side push drive body 240 and the screw fastening device.

[0045] As an optional implementation method, refer to Figure 3 , Figure 4 The first side baffle 310 has a third through hole 313. The second telescopic body 421 passes through the third through hole 313, thereby passing through the first side baffle 310 and blocking the locking device 101 in the second direction. The third through hole 313 can be configured as a strip-shaped hole extending along the first direction. The first driving assembly 430 is used to move the second telescopic body 421 within the third through hole 313 along the first direction. In this embodiment, the first direction is... Figure 1 The left and right directions are shown, and the second direction is... Figure 1 As shown in the front-back direction, the conveying assembly 100 conveys the screw fastening device 101 from left to right. It can be understood that the dimension of the third through hole 313 in the first direction is larger than the dimension of the second telescopic body 421 in the first direction, so as to facilitate the movement of the second telescopic body 421 in the first direction and improve the structural compactness of the screw fastening device.

The cylinder seat of the first forward drive cylinder is fixedly connected to the first side upright plate 314, improving installation convenience; the cylinder rod of the first forward drive cylinder is connected to the second telescopic drive body 422 to drive the second telescopic body 421 to slide along the first direction.

[0047] Furthermore, both the first side baffle 310 and the second side baffle 320 may be provided with a first telescopic component 410, and both the first side baffle 310 and the second side baffle 320 may be provided with a second telescopic component 420.
