Description

Technical Field

[0001] This utility model relates to the field of screw fastening equipment technology, and in particular to a four-track screw fastening device. Background Technology

[0002] Screw fastening is a common fixing method, and screw fastening equipment is now widely used to achieve this action, improving efficiency and ensuring fastening quality. However, existing multi-track screw fastening equipment typically uses one or two screw fastening mechanisms in conjunction with multiple tracks, for example, a 1:1 or 1:2 ratio of screw fastening mechanisms to tracks. This layout means that the number of screw fastening mechanisms usually does not exceed two to ensure that interference is minimized when the screw fastening mechanisms move on the gantry.

[0003] Obviously, when there are two screw-locking mechanisms and four transmission mechanisms, the efficiency of the transmission mechanisms is usually greater than that of the screw-locking mechanisms, resulting in the equipment not reaching its maximum efficiency. Summary of the Invention

[0004] This utility model addresses the problems of the prior art by providing a four-track screw-locking device that enables four screw-locking mechanisms to cooperate with four transmission mechanisms, thereby further improving the efficiency of operation.

[0005] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: This utility model provides a four-track screw-locking device, which includes a body, two gantry frames, and four transmission mechanisms. The gantry frames are equipped with guide rails, and two locking mechanisms are slidably arranged on the guide rails. All four transmission mechanisms are located inside the gantry frames. The transmission mechanism is used to transport products and to hold and position them when they are in place. The fastening mechanism is used to identify the location of the screw holes in the product and to fasten the screws in the screw holes.

[0006] Furthermore, the transmission mechanism includes a transmission frame, a belt module, an identification module, a lifting module, a clamping module, and a pressing module, all mounted on the transmission frame. The belt module is used to support and transmit the product, the identification module is used to identify whether the product is in place, the lifting module is used to lift the product when it is transported to place by the belt module, the clamping module is used to push one side of the product to make the product in place, and the pressing module is used to press and fix the product onto the lifting module. There are two identification modules, two lifting modules, two clamping modules, and two pressing modules.

[0008] Furthermore, the clamping module includes a fixed component, a movable component, and a clamping drive component. The fixed component and the movable component are located on the top two sides of the transfer frame, respectively. The clamping drive component is used to drive the movable component to move back and forth horizontally, and the clamping drive component is used to push the product against the fixed component.

[0009] Furthermore, the pressing module includes a pressing frame, a pressing drive component, and a pressing guide component. The pressing drive component and the pressing guide component are both installed on the pressing frame. The bottom of the pressing drive component is connected to the pressing drive component and the pressing guide component respectively.

[0010] Furthermore, the locking mechanism includes an electric screwdriver module, a lifting module, and a traversing module. The traversing module is mounted on the guide rail, the lifting module is mounted on the output end of the traversing module, and the electric screwdriver module is mounted on the output end of the lifting module.

[0011] Furthermore, only one locking mechanism on each guide rail is equipped with a vision device, and the locking mechanisms with vision devices on two guide rails are not located on the same side; the vision device is located on the side of the electric screwdriver module away from the other locking mechanism.

[0012] Furthermore, the vision device includes a camera and an aperture element, which is located directly below the camera. The aperture element has a light-enhancing aperture, and multiple LED beads are evenly distributed on the inner wall of the light-enhancing aperture.

[0013] Furthermore, the transverse module includes an X-axis driver and a Y-axis driver. The X-axis driver is mounted on the guide rail, the Y-axis driver is mounted on the output end of the X-axis driver, and the lifting module is located at the output end of the Y-axis driver.

Detailed Implementation

[0022] Example 1 This embodiment provides a four-track screw fastening device, including a body (not shown in the figure), two gantry frames 1, both of which are set on the body, and four transmission mechanisms 2. The gantry frames 1 are provided with guide rails, and two locking mechanisms 3 are slidably arranged on the guide rails. The four transmission mechanisms 2 are all located inside the gantry frames 1. The transmission mechanism 2 is used to transmit the product and to hold and position the product when it is in place. The fastening mechanism 3 is used to identify the screw hole positions of the product and to fasten the screws to the screw holes of the product.

[0023] Specifically, the system features two gantry frames 1 connected by a crossbeam 4 to form a single unit, enhancing the stability of the gantry frames 1 and the locking mechanisms 3 mounted on them. Since each gantry frame 1 is equipped with two locking mechanisms 3, each mechanism 3 can tighten screws on the products of the two transmission mechanisms 2. This means that two transmission mechanisms 2 on the same side can effectively utilize two locking mechanisms 3 for coordinated locking, thus ensuring efficiency.

[0024] In this embodiment, the transmission mechanism 2 includes a transmission frame 21, a belt module 22, an identification module 23, a lifting module 24, a clamping module 25, and a pressing module 26, all of which are disposed on the transmission frame 21. The belt module 22 is used to support and transmit the product, the identification module 23 is used to identify whether the product is in place, the lifting module 24 is used to lift the product when it is transmitted to place by the belt module 22, the clamping module 25 is used to push one side of the product to make the product in place, and the pressing module 26 is used to press and fix the product onto the lifting module 24. There are two of each of the following modules: identification module 23, lifting module 24, clamping module 25, and pressing module 26.

[0025] Specifically, the transmission mechanism 2 can fix two products at a time, with each product secured by a screw fastening mechanism 3. During operation, the product is placed on the fixture and transported to its position via the belt module 22. Then, the lifting module 24 is activated to raise the fixture until it is detached from the belt. Next, the clamping module 25 is activated to position the fixture horizontally. Finally, the pressing module 26 is pressed down to cooperate with the lifting module 24 in clamping the fixture. This process positions the product in different dimensions, ensuring stable and accurate screw fastening.

[0026] Specifically, the lifting module 24 includes a lifting member 241, a positioning member 242, a lifting driver 243, and a positioning driver 244. The lifting driver 243 is used to drive the lifting member 241 to rise and fall, and the positioning driver 244 is used to drive the positioning member 242 to rise and fall. The lifting member 241 is used to lift the product so that the product is removed from the belt module 22, and the positioning member 242 is used to insert the product for positioning.

[0027] Both the lifting driver 243 and the positioning driver 244 are preferably cylinders. That is, during lifting, in addition to using the lifting member 241 to support and lift the product fixture, after clamping, the positioning member 242 is inserted into the corresponding hole of the fixture to achieve secondary positioning of the fixture, thus ensuring stability.

[0028] Specifically, the clamping module 25 includes a fixed member 251, a movable member 252, and a clamping drive member 253. The fixed member 251 and the movable member 252 are located on the top two sides of the transmission frame 21, respectively. The clamping drive member 253 is used to drive the movable member 252 to move back and forth horizontally, and the clamping drive member 253 is used to push the product against the fixed member 251.

[0029] The clamping drive component 253 is preferably a cylinder. By using the cooperation of the movable component 252 and the fixed component 251, the product is positioned in the horizontal direction, so that the product's posture and position are basically consistent when the screw is tightened.

[0030] Specifically, the pressing module 26 includes a pressing frame 261, a pressing drive component 262, and a pressing guide component 263. The pressing drive component 262 and the pressing guide component 263 are both installed on the pressing frame 261. The bottom of the pressing drive component 262 is connected to the pressing drive component 262 and the pressing guide component 263 respectively. The pressing drive component 262 is used to drive the pressing frame 261 to rise and fall. The pressing frame 261 is used to press the product onto the lifting module 24.

[0031] The holding drive 262 is preferably a cylinder. The holding frame 261 is in a raised state when the product is being transported, so as to make way for the product. The holding is only performed after the product is in place and lifted.

[0032] Example 2 In this embodiment, the locking mechanism 3 includes an electric screwdriver module 31, a lifting module 32, and a traversing module 33. The traversing module 33 is mounted on a guide rail, the lifting module 32 is mounted on the output end of the traversing module 33, and the electric screwdriver module 31 is mounted on the output end of the lifting module 32.

[0033] At least one locking mechanism 3 on each guide rail is equipped with a vision device 34, which is used to obtain the position of the screw holes on the product.

[0034] Specifically, the screws fastened by each fastening mechanism 3 may be of the same specification, or the screws fastened by the electric screwdriver module 31 of the fastening mechanism 3 located on the same side may be of different specifications.

[0035] In this embodiment, in addition to achieving the effects described in Embodiment 1, it also allows for changing the specific position of the product in the transmission mechanism 2. Specifically, if a product requires the installation of two different screw sizes, or if there are too many screw positions, the preceding installation mechanism 3 can install one type of screw / screws in the front half of the product, while the subsequent installation mechanism 3 installs the other type of screw / screws in the rear half of the product. This method enables the installation of different types of screws in this embodiment, or it can improve installation efficiency by installing screws at both ends of the product separately.

[0036] It should be noted that the function of the vision device 34 is to obtain the position of the screw holes that need to be fastened on the product, as well as the hole specifications of the screws, so that the two fastening mechanisms 3 on the same side can perform their respective functions without interference or duplicate / incorrect fastening positions.

[0037] Specifically, each guide rail has only one locking mechanism 3 with a vision device 34, and the locking mechanisms 3 with vision devices 34 on two guide rails are not located on the same side; the vision device 34 is located on the side of the electric screwdriver module 31 away from the other locking mechanism 3, which helps to save costs.

[0038] Furthermore, the vision device 34 includes a camera 341 and an aperture 342. The aperture 342 is located directly below the camera 341 and has a light-enhancing hole 343. Multiple LED beads 344 are evenly distributed on the inner sidewall of the light-enhancing hole 343.

[0039] In this embodiment, the transverse module 33 includes an X-axis driver 331 and a Y-axis driver 332. The X-axis driver 331 is mounted on the guide rail, the Y-axis driver 332 is mounted on the output end of the X-axis driver 331, and the lifting module 32 is located at the output end of the Y-axis driver 332.

[0040] The X-axis driver 331, Y-axis driver 332, and lifting module 32 are either pneumatic or electric cylinders, belonging to conventional linear drive modules, which enable the electric screwdriver module 31 to move in three dimensions, ensuring flexibility.

Although the present utility model has been disclosed above with reference to a preferred embodiment, it is not intended to limit the present utility model.
