[0002] During the production of air conditioner outdoor units, fasteners often need to be tightened onto the unit. For example, multiple screws are required to secure the panel of the outdoor unit to it. Manual installation of fasteners is inefficient, labor-intensive, and prone to errors such as missing or improperly installed fasteners.

[0003] In related technologies, to improve product manufacturing efficiency, fasteners need to be installed on products on the production line. This requires production line workers to install fasteners quickly and accurately. This further increases the labor intensity of production line workers and also increases the defective product rate caused by missing fasteners. Utility Model Content

[0004] This invention provides a fastener installation device to improve the efficiency of fastener installation on the production line.

[0005] This utility model provides a fastener installation device, including a frame; a conveyor line installed on the frame for transporting products to and from the installation station; a baffle assembly installed on the frame for blocking or releasing products at the installation station; and a tightening assembly disposed on one side of the conveyor line for locking fasteners onto the products located at the installation station.

[0006] In one embodiment, the conveyor line includes a plurality of rollers spaced apart, with a gap formed between adjacent rollers; the baffle assembly also includes a lifting drive mounted on a frame, on which a first baffle is mounted, the first baffle being located below the gap, the lifting drive being used to drive the first baffle to move up and down through the gap, so that the first baffle is moved above or below the conveyor line, thereby achieving the blocking or release of products at the installation station.

[0007] In one embodiment, the lifting drive is a cylinder.

[0008] In one embodiment, a second baffle is also provided on the frame; the barrier assembly also includes a horizontal drive member installed on the frame, the horizontal drive member is connected to a clamping plate, the clamping plate and the second baffle are spaced apart along the length direction of the first baffle, and the horizontal drive member is used to drive the clamping plate to horizontally push the product so that the product is pressed against the second baffle.

[0009] In one embodiment, the horizontal drive is located below the conveyor line and the clamp is located above the conveyor line; the baffle assembly also includes a bracket that passes through the gap to connect the horizontal drive and the clamp.

[0010] In one embodiment, the tightening assembly includes a moving mechanism on which an electric screwdriver is mounted. The moving mechanism is used to move the electric screwdriver, which is used to install fasteners onto the product.

[0011] In one embodiment, the moving mechanism is a three-axis linear module to drive the electric screwdriver to move in the XYZ directions.

[0012] In one embodiment, a camera is mounted on the electric screwdriver, and the camera is used to identify the position of the mounting holes on the product that correspond to the fasteners.

[0013] In one embodiment, a frame is provided on one side of the frame, and multiple tightening components are installed on the frame. Each tightening component corresponds to a fastener that needs to be installed on the product, and each tightening component can tighten simultaneously.

[0039] The present invention will be further described below with reference to the accompanying drawings.

[0040] The embodiments provided in this application are fastener mounting devices; see [link to relevant documentation]. Figures 1 to 4 As shown, the fastener installation device includes: a frame 100, on which a conveyor line 200 and a baffle assembly 300 are mounted. The conveyor line 200 is used to transport the product 900 to the installation station, and also to transport the product 900 out of the installation station. The baffle assembly 300 is used to block or release the product 900 at the installation station.

[0041] The fastener installation device also includes a tightening assembly 400 disposed at one point on the conveyor line 200. The tightening assembly 400 is used to lock the fastener onto the product 900 at the installation station. In this application, a support frame 500 is also provided at one point on the frame 100, and the tightening assembly 400 is mounted on the support frame 500. In some other implementations, the frame 100 can be widened so that the tightening assembly 400 can be directly mounted on the frame 100.

[0042] When using the fastener installation device provided in this application, the products 900 that require fastener installation are first placed sequentially on the conveyor line 200. The conveyor line 200 gradually transports the products 900 to the installation station. The baffle assembly 300 installed on the frame 100 stops the products 900 that have moved to the installation station. The tightening assembly 400 then installs the fasteners on the products 900 that are stopped by the baffle assembly 300. Because the baffle assembly stops the products 900 at the installation station, the stability of the products 900 is improved when the tightening assembly 400 tightens the fasteners. This avoids fastener misalignment caused by movement of the products 900 during the tightening process, and improves the accuracy of the tightening assembly 400 in tightening the fasteners.

[0043] The tightening assembly 400 provided in this application may have a structure with a moving mechanism 410 and an electric screwdriver 420. The moving mechanism 410 drives the electric screwdriver 420 to move, so that the electric screwdriver 420 is aligned with the mounting hole 910 of the product 900 to install the fastener.

[0044] The fasteners referred to in this application can be threaded fasteners such as screws, bolts, and nuts, which can be tightened and fixed by rotating the threaded fasteners with an electric screwdriver 420.

[0045] See Figure 1 , Figure 2 as well as Figure 5 As shown, in some implementations, the conveyor line 200 includes a plurality of rollers 210 spaced apart, with adjacent rollers 210 forming a gap 220; the baffle assembly 300 also includes a lifting drive 310 mounted on the frame 100, the lifting drive 310 having a first baffle 320 mounted on it, the first baffle 320 being located below the gap 220, the lifting drive 310 being used to drive the first baffle 320 to move up and down through the gap 220, so that the first baffle 320 is moved above the conveyor line 200 or below the conveyor line 200.

[0046] When the lifting drive 310 drives the first baffle 320 to move above the conveyor line 200, the first baffle 320 can be used to block the product 900, preventing the product 900 from moving out of the installation position, thereby improving the stability of the fastener installation process of the tightening component 400 and preventing the product 900 from moving with the conveyor line 200 during the tightening process of the tightening component 400 tightening the fastener.

[0047] When the lifting drive 310 moves the first baffle 320 below the conveyor line 200, the first baffle 320 will not obstruct the product 900. This allows the product 900 to be moved out of the installation station by the transport of the conveyor line 200, and then enter the next station for the next process.

[0048] Understandably, to achieve automated control, sensors, such as laser sensors or ultrasonic sensors, can be installed at the installation station to detect whether product 900 has moved to the installation station. When the sensor detects product 900 moving to the installation station, it controls the lifting drive 310 in the baffle assembly 300 to move the first baffle 320 upwards, thus blocking product 900 at the installation station. After the tightening assembly 400 has tightened product 900, the lifting drive 310 is controlled to move the first baffle 320 downwards, allowing product 900 at the installation station to be conveyed to the next station via the conveyor line 200.

[0049] To achieve automated control, a controller can be installed on the frame 100. The controller can integrate a PLC module. By connecting the controller to sensors located at the installation station, the controller can identify whether product 900 has entered the installation station. The controller is also connected to the tightening assembly 400 so that it can flexibly control the working state of the tightening assembly 400 and determine whether the fastener tightening work has been completed based on the working state of the tightening assembly 400.

[0050] Since the conveyor line 200 in this application uses rollers 210 for conveying at the installation station, a gap 220 is formed between adjacent rollers 210, which allows the first baffle 320 to move up and down. The lifting drive 310 and the first baffle 320 can be placed below the conveyor line 200, making the conveyor line 200 more aesthetically pleasing.

[0051] The conveyor line 200 in this application uses rotating rollers 210 to transport the product 900. The rollers 210 can be driven to rotate synchronously by a chain structure or by a belt structure.

[0052] See Figure 2 as well as Figure 5 As shown, the length direction of the first baffle 320 is parallel to the axis of the roller 210, which can better block the product 900.

[0053] In some implementations, the lifting drive component 310 is a cylinder. Compared with other lifting drive structures, the cylinder is more responsive and can move the first baffle 320 above the conveyor line 200 to block the product 900 more quickly, or move the first baffle 320 above the conveyor line 200 to below the conveyor line 200 to release the product 900.

[0054] See Figure 1 , Figure 2 as well as Figure 6 As shown, in some implementations, a second baffle 360 ​​is also installed on the frame 100. The barrier assembly also includes a horizontal drive member 330 installed on the frame 100. The horizontal drive member 330 is connected to a clamping plate 340. The clamping plate 340 and the second baffle 360 ​​are arranged at intervals along the length direction of the first baffle 320. The horizontal drive member 330 is used to drive the clamping plate 340 to move horizontally, pushing the product 900 to abut against the second baffle 320, thereby locking the product 900.

[0055] The clamping plate 340 and the second baffle 360 ​​are located on opposite sides of the installation station. When the product 900 is pressed together by the clamping plate 340 and the second baffle 360, the product 900 is locked at the installation station.

[0056] Because of the clamping plate 340 and the horizontal drive component 330, the product 900 can be pressed firmly by the drive component 330, preventing the product 900 from moving and improving the stability of the product 900. In other words, after the product 900 is pressed firmly by the clamping plate 340, the tightening component 400 can tighten the fasteners more accurately, avoiding improper installation of the fasteners due to the shaking of the product 900 during the tightening process.

[0057] In actual operation, the horizontal drive component 330 is connected to the controller. After the sensor at the installation station detects that the product 900 has entered the installation station, the controller controls the lifting drive component 310 to raise the first baffle 320, and the controller also controls the horizontal drive component 330 to move the clamping plate 340 horizontally. At this time, the first baffle 320 can block the product 900 at the installation station, and the clamping plate 340 can clamp the product 900, thus locking the product 900.

[0058] See Figure 1 as well as Figure 6 As shown, the horizontal drive member 330 is used to move the clamping plate 340 along a first direction, which is perpendicular to the transport direction of the transport line. When the horizontal drive member 330 drives the clamping plate 340 to move, the clamping plate 340 is in contact with one side of the product 900, while the second baffle 360 ​​is in contact with the other side of the product 900, thus clamping the product 900. At this time, the bottom surface of the product 900 is supported on the support line, and the first baffle 320, the clamping plate 340, and the second baffle 360 ​​respectively abut against three different sides of the product 900, thereby positioning the product 900.

[0059] In some implementations, the horizontal drive 330 can be a cylinder, which has a faster response speed. In other implementations, the horizontal drive 330 can also be an electric cylinder, which simplifies control.

[0060] See Figure 1 as well as Figure 6 As shown, in some implementations, the horizontal drive member 330 is located below the conveyor line 200, and the clamping plate 340 is located above the conveyor line 200; the baffle assembly 300 also includes a bracket 350, which passes through the gap 220 to connect the horizontal drive member 330 and the clamping plate 340. Since the conveyor line 200 in this application uses rollers 210 for conveying, the bracket 350 can pass through the gap 220 between the rollers 210 without affecting the conveying function of the conveyor line 200. Because the horizontal drive member 330 can be arranged below the conveyor line 200, the air supply line connecting to the conveyor line 200 can be hidden below the conveyor line 200, which is more aesthetically pleasing and avoids the impact of the air supply line on the transportation of the product 900.

[0061] See Figure 6 As shown, the clamping plate 340 has a guide bend on the side away from the first baffle 320, which can move the clamping plate 340 into place as soon as the product 900 enters the installation station. The guide bend of the clamping plate 340 can guide the product 900 to move toward the side where the second baffle 360 ​​is provided.

[0062] See Figure 1 , Figure 7 as well as Figure 8 As shown, in some implementations, the tightening assembly 400 includes a moving mechanism 410, on which an electric screwdriver 420 is mounted. The moving mechanism 410 is used to move the electric screwdriver 420, which is used to install fasteners onto the product 900. The electric screwdriver 420, also known as an electric screwdriver, is a power tool used for tightening and loosening screws and nuts. By fixing the electric screwdriver 420 to the moving mechanism 410, the position of the electric screwdriver 420 can be adjusted by the moving mechanism 410, which is more convenient than manually adjusting the position of the electric screwdriver 420, requires no manual operation, and allows for long-term operation.

[0063] See Figures 7 to 12 As shown, in some implementations, the moving mechanism 410 is a three-axis linear module to drive the electric screwdriver 420 to move linearly in the X, Y, and Z directions. Specifically, the moving mechanism 410 includes a first module 411, a second module 412, and a third module 413, wherein the first module 411 includes a first slide rail 4111 extending along the X direction (see image). Figure 13 As shown), the first slider 4112 (visible) Figure 13 (as shown) and the first drive unit 4113 (visible) Figure 13 As shown, the first slider 4112 is slidably mounted on the first slide rail 4111 and connected to the first driving member 4113. The first driving member 4113 drives the first slider 4112 to slide linearly along the first slide rail 4111. The second module 412 is mounted on the first slider 4112 of the first module 411. When the first driving member 4113 drives the first slider 4112 to slide in the X direction, the coordinates of the second module 412, the third module 413, and the electric screwdriver 420 in the X direction are adjusted synchronously. It can be understood that the first driving member 4113 can be an electric screw or a rack and pinion, used to drive the first slider 4112 to move relative to the first slide rail 4111 in the X direction.

[0064] Similarly, the second module 412 includes a second slide rail, a second slider, and a second driving member. The second slider is slidably mounted on the second slide rail. The second slide rail is fixedly connected to the first slider 4112 and extends along the Y direction. The second driving member is used to drive the second slider to slide relative to the second slide rail.

[0065] The third module 413 includes a third slide rail, a third slider, and a third driving component. The third slide rail is fixedly connected to the second slider. When the second driving component moves the second slider along the Y direction, the third slide rail moves synchronously along the Y direction. The third slide rail extends along the Z direction, and the third slider is slidably mounted on the third slide rail. The third driving component is used to drive the third slider to move along the third slide rail.

[0066] The electric screwdriver 420 is fixedly connected to the third slider. When the position of the electric screwdriver 420 is adjusted by the moving mechanism 410, the position of the electric screwdriver 420 in the X direction can be adjusted by the first driving member 4113, the position of the electric screwdriver 420 in the Y direction can be adjusted by the second driving member, and the position of the electric screwdriver 420 in the Z direction can be adjusted by the third driving member. Since the three directions X, Y, and Z are perpendicular to each other, the electric screwdriver 420 can be adjusted in three-dimensional space, thus expanding the adjustment range of the electric screwdriver 420.

[0067] In some implementations, the X and Y directions are two mutually perpendicular horizontal directions, while the Z direction is a vertical direction.

[0068] Figure 8 , 9 In the tightening assembly 400 shown, the second module 412 is mounted above the first module 411, while the third module 413 is mounted to the left of the second module 412. Figure 10 , Figure 11 In the tightening assembly 400 shown, the second module 412 is mounted above the first module 411, and the third module 413 is mounted above the second module 412.

[0069] See Figure 1 , Figure 7 as well as Figure 12 As shown, in some implementations, a camera 710 is mounted on the electric screwdriver 420. The camera 710 is used to identify the position of the mounting hole 910 on the product 900 corresponding to the fastener. The camera 710 identifies the position of the mounting hole 910 and then transmits the identification result to the controller. The controller determines the movement path of the electric screwdriver 420 based on the current position of the electric screwdriver 420 and the position of the mounting hole 910, thereby using the moving mechanism 410 to move the electric screwdriver 420 to the position corresponding to the mounting hole 910.

[0070] Compared to manual identification, camera 710 offers higher stability. In some implementations, a light source 720 is also installed at the electric screwdriver 420, which illuminates the product 900, thereby improving the identification accuracy of camera 710 and preventing a decrease in identification accuracy due to dim lighting.

[0071] In some implementations, the light source 720 forms a through hole, and the camera of the camera 710 can identify the position of the mounting hole 910 on the product 900 through the through hole formed by the light source 720.

[0072] See Figure 1 as well as Figure 7 As shown, a frame 500 is also provided on one side of the frame 100. Multiple tightening components 400 are installed on the frame 500. Each tightening component corresponds to a fastener that needs to be installed on the product 900. Each tightening component 400 can tighten simultaneously.

[0073] Specifically, in this application, three screws need to be installed on the product 900 at the installation station. Therefore, three tightening components 400 are installed on the frame 500. Each tightening component 400 installs one screw on the product 900. The three tightening components 400 can work simultaneously, which further improves the installation efficiency of the fasteners.

[0074] Understandably, if it is necessary to install n tightening components 400 on product 900 at the installation station, then n tightening components 400 can be installed on frame 500, with each tightening component 400 performing the tightening of one screw.

[0075] Since the moving mechanism 410 in this application is a three-axis linear module, it can easily adjust the position of the electric screwdriver 420 to complete the installation of screws. Compared with a six-axis robot, it occupies a smaller volume and can arrange multiple tightening components 400 in a small space to tighten multiple screws at the same time.

[0076] See Figure 1 , Figure 7 as well as Figure 12 As shown, in some implementations, the tightening assembly 400 is connected to a feeding assembly 600, which includes a conveying pipe 620 connected to the electric screwdriver 420. The conveying pipe 620 is connected to a feeder 610, which is used to blow fasteners along the conveying pipe 620 to the electric screwdriver 420.

[0077] In other words, the feeding assembly 600 can be used to automatically feed screws, eliminating the need for manual screw feeding of the electric screwdriver 420 during use, thus further improving screw tightening efficiency. Moreover, compared to other transportation methods, the blow-feed screw method can quickly complete screw transportation, and the mechanism is relatively simple and cost-effective.

[0078] Specifically, a beak 630 is installed on the third module 413 of the moving mechanism 410. The feeder 610 can blow screws to the beak 630. A locking cylinder 430 and a linear guide rail 440 are installed on the moving mechanism 410. An electric screwdriver 420 is slidably installed on the linear guide rail 440 and is connected to the locking cylinder 430. By extending the locking cylinder 430, the electric screwdriver 420 can slide along the linear guide rail 440.

[0079] When tightening screws, the controller first controls the feeder 610 to blow the screw through the conveying pipe 620 to the beak 630. Then, the controller controls the tightening cylinder 430 to extend, driving the electric screwdriver 420 to slide along the linear guide rail 440, so that the screwdriver bit 421 of the electric screwdriver 420 is inserted into the beak 630, connecting the bit 421 to the screw in the beak 630. Then, the controller controls the electric screwdriver 420 to rotate the bit 421, thereby rotating the screw on the bit 421 and tightening the screw.

[0080] After the screw is tightened, the tightening cylinder 430 can be retracted to drive the electric screwdriver 420 to slide along the linear guide rail 440, so that the screwdriver bit 421 of the electric screwdriver 420 is retracted from the beak 630. Then, the feeder 610 is controlled to blow air to send the screw from the conveying pipe 620 to the beak 630 for the next screw tightening operation.

[0081] Although the present invention has been described with reference to preferred embodiments, various modifications can be made thereto and components can be replaced with equivalents without departing from the scope of the invention. In particular, the technical features mentioned in the various embodiments can be combined in any manner, provided there is no structural conflict. The present invention is not limited to the specific embodiments disclosed herein, but includes all technical solutions falling within the scope of the claims.
