Description

Technical Field

[0001] This utility model relates to the field of screw fastening, specifically a modular screw fastening device. Background Technology

[0002] Screw-fastening devices are used to fasten screws onto different components of a product to facilitate assembly. Since product assembly involves multiple steps, screw-fastening is necessary before transferring the product to subsequent inspection stations. If the screw-fastening device only has one docking port, it requires connecting the product along with a fixture. This limits its application to specific production lines or spaces. For example, when production space is limited and the production line cannot be laid out long enough, modular screw-fastening devices are difficult to integrate with the production line. Similarly, having only one interface is inconvenient when receiving different semi-finished products.

[0003] For example, Chinese patent CN112828578B discloses a modular automatic screw-locking device for multi-station collaborative operation on a production line, comprising: a base, a transport mechanism, a clamping mechanism, and a screw-locking mechanism; the transport mechanism is disposed on the upper surface of the base, with its front end flush with the front end of the base and its rear end flush with the rear end of the base; the clamping mechanisms are symmetrically arranged on the left and right sides of the transport mechanism; the screw-locking mechanism is located above the transport mechanism and is fixedly connected to the base; a first locking part is provided at the front end of the base, and a second locking part corresponding to the first locking part is provided at the rear end of the base. The aforementioned modular automatic screw-locking device for multi-station collaborative operation connects to external equipment via the transport mechanism, and can only connect to one production line at a time, limiting its application space and application scenarios.

[0004] Therefore, it is necessary to provide a modular screw-locking device. Utility Model Content

[0005] The present invention provides a modular screw-locking device, which effectively solves the problem that the modular screw-locking mechanism cannot only be connected to one external device from one direction.

[0006] The technical solution adopted in this utility model is:

[0007] A modular screw-locking device includes a frame, a receiving conveyor line arranged along the Y-axis on the frame, a loading mechanism arranged on the frame, a feeding conveyor line arranged along the X-axis on the frame, and a screw-locking mechanism arranged on the frame. The two ends of the feeding conveyor line can be connected to external flow lines respectively. The receiving conveyor line includes a first base arranged on the frame, a first guide rail and a first drive assembly arranged along the Y-axis, a first slide cylinder slidably arranged on the first guide rail, and a first gripper arranged at the output end of the first slide cylinder. The first base has corresponding slots extending along the Y-axis on both sides.

[0008] Furthermore, the feeding conveyor line is flush with both ends of the frame. The feeding conveyor line includes a double belt conveyor line arranged on the frame along the X-axis, two lifting components arranged on the frame corresponding to the screw locking mechanism and the receiving conveyor line, and a clamping component arranged on the frame corresponding to the screw locking mechanism.

[0021] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0022] like Figure 1 and Figure 2 As shown, an embodiment of this application provides a modular screw-locking device, the structure of which includes a frame 1, a receiving conveyor line 4 arranged along the Y-axis direction on the frame 1, a loading mechanism 3 arranged on the frame 1, a feeding conveyor line 2 arranged along the X-axis direction on the frame 1, and a screw-locking mechanism 5 arranged on the frame 1. The feeding conveyor line 2 can be connected to external flow lines at both ends. The receiving conveyor line 4 includes a first base 41 arranged on the frame 1, a first guide rail 45 and a first drive assembly 42 arranged along the Y-axis direction, a first slide cylinder 43 slidably arranged on the first guide rail 45, and a first gripper 44 arranged at the output end of the first slide cylinder 43. The first base 41 has corresponding slots 400 extending along the Y-axis direction on both sides. The first drive assembly 42 is one of a linear module, a synchronous belt transmission mechanism, or a lead screw.

[0023] It should be noted that this application uses a PLC control system to control the operation of the receiving conveyor line 4, the loading mechanism 3, the feeding conveyor line 2, and the screw-locking mechanism 5. The receiving conveyor line 4 is responsible for receiving the first fixture from the external equipment. The first drive assembly 42 drives the first slide cylinder 43 to slide along the first guide rail 45. The receiving conveyor line 4 will transfer the first fixture from the external equipment, and the feeding conveyor line 2 will connect with the external flow line to receive the second fixture from the external flow line.

[0024] In actual use, both ends of the feeding conveyor line 2 are flush with the sides of the frame 1, so that one end of the feeding conveyor line 2 connects to the external flow line, and the other end of the feeding conveyor line 2 corresponds to the external receiving mechanism. The receiving conveyor line 4 connects to the external equipment. After connecting to the external equipment through the receiving conveyor line 4, the receiving conveyor line 4 receives the first fixture: the first drive component 42 drives the first slide cylinder 43 to move the first gripper 44 away from the feeding conveyor line 2. Then, the first slide cylinder 43 drives the first gripper 44 to extend, so that the first gripper 44 clamps the first fixture. Then, the output end of the first slide cylinder 43 retracts, driving the first gripper 44 and the first fixture clamped by the first gripper 44 to move synchronously, so that the two sides of the first fixture extend into the two slots 400 respectively. Then, the first drive assembly 42 drives the first slide cylinder 43 and the first gripper 44 to slide the first fixture along the slot 400 to one side of the feeding conveyor line 2. Subsequently, the loading mechanism 3 transfers the product in the first fixture to the second fixture in the feeding conveyor line 2. Then, the receiving conveyor line 4 sends the first fixture back to the external equipment, and the feeding conveyor line 2 transports the second fixture to the corresponding position of the screw-locking mechanism 5, using the screw-locking mechanism 5 to fasten the screws on the product in the second fixture.

[0025] In the above design, the entire device can interface with two external devices, expanding the application scenarios. It can transfer products to be assembled from external devices to the screw-locking mechanism 5 for screw-locking. The entire receiving and conveying line 4 has a simple and compact structure and can use the slot 400 to guide the sliding of the first fixture, ensuring that the first fixture moves stably in the device and external devices.

[0026] Specifically: such as Figure 1 As shown, the two ends of the feeding conveyor line 2 are flush with the two sides of the frame 1 (the figure shows a slight error). The feeding conveyor line 2 includes a double belt conveyor line 21 arranged along the X-axis on the frame 1, two lifting components 22 arranged on the frame 1 corresponding to the screw locking mechanism 5 and the receiving conveyor line 4 respectively, and a pressing component 23 arranged on the frame 1 corresponding to the screw locking mechanism 5. The pressing component 23 corresponds to one of the lifting components 22.

[0027] For ease of understanding, the lifting component 22 corresponding to the receiving conveyor line 4 is described as lifting component 22 No. 1, and the lifting component 22 corresponding to the screw locking mechanism 5 is described as lifting component 22 No. 2.

[0028] In actual use, the two ends of the feeding conveyor line 2 are flush with the two sides of the frame 1, so that one end of the feeding conveyor line 2 connects with the external flow line, and the other end of the feeding conveyor line 2 corresponds to the external receiving mechanism. When the second fixture is ready to receive the product transferred from the first fixture by the feeding mechanism 3, the first lifting component 22 lifts the second fixture from the double belt conveyor 21. Then the second fixture receives the product. Subsequently, the first lifting component 22 resets and puts the second fixture back into the double belt conveyor 21. Then the second fixture is conveyed along the double belt conveyor 21 to above the second lifting component 22. Then the second lifting component 22 drives the second fixture to lift and detach from the double belt conveyor 21. Then the clamping component 23 clamps the upper end of the product, so that the second lifting component 22 and the clamping component 23 cooperate to achieve product positioning. Then the screw locking mechanism 5 locks the screws on the product. After the screws are locked on the product, the second lifting component 22 moves down, so that the second fixture is placed back on the double belt conveyor 21 and flows to the external receiving mechanism.

[0029] In the above design, the structural design and specific implementation of the feeding conveyor line 2 can effectively realize the receiving of the second fixture, the receiving of the material in the second fixture, and the fastening of the screws on the product in the second fixture.

[0030] Specifically: such as Figure 4 As shown, the lifting assembly 22 includes a second base 221 mounted on the frame 1, a second lifting frame 222 slidably mounted on the second base 221, a second cylinder 223 mounted on the second base 221 for driving the second lifting frame 222 to rise and fall, and a positioning post 224 mounted on the second lifting frame 222. It should be noted that the lower end of the second fixture is provided with a positioning hole that mates with the positioning post 224.

[0031] In actual use, cylinder 223 drives lifting frame 222 to rise, causing it to lift positioning column 224 and insert it into positioning hole, thus lifting fixture 2 and allowing it to receive material or lock product onto fixture 2. Then, cylinder 223 drives lifting frame 222 to fall, causing fixture 222 to be repositioned on double belt conveyor line 21.

[0032] In the above design, the structural design and specific implementation of the lifting component 22 can achieve the lifting of the jig, and the positioning pin 224 and the positioning hole cooperate to ensure the lifting accuracy and that the second jig will not slip after being lifted.

[0033] Specifically: such as Figure 4As shown, the clamping assembly 23 includes a No. 6 seat 231 mounted on the frame 1, a lifting pressure frame 232 slidably mounted on the No. 6 seat 231, two pressure sensors 233 mounted on the lower end face of the lifting pressure frame 232, two connecting blocks 234 respectively connected to the lower ends of the two pressure sensors 233, and two electric cylinders 235 respectively mounted on the No. 6 seat 231 with their output ends connected to the lower end face of the connecting blocks 234. The electric cylinders 235 are used to drive the connecting blocks 234 to drive the pressure sensors 233 and the lifting pressure frame 232 to move up and down synchronously. The lifting pressure frame 232 is provided with a plurality of clearance holes 230 for avoiding the locking screw mechanism 5.

[0034] In actual use, after the second fixture is lifted by the lifting assembly 22, the output ends of the two electric cylinders 235 descend synchronously. This causes the electric cylinders 235 to drive the connecting block 234, pressure sensor 233, and lifting pressure frame 232 to move downwards simultaneously. The downward movement of the lifting pressure frame 232 compresses the upper surface of the product in the second fixture, ensuring the product is fixed within it. When the product is pressed by the lifting pressure frame 232, the pressure sensor 233 monitors the pressure exerted on the product by the lifting pressure frame 232 in real time. When the pressure value reaches a predetermined value, the PLC control system stops the movement of the output end of the electric cylinder 235. Subsequently, the screw fastening mechanism passes through the clearance hole 230 to fasten the screws onto the product. Then, the electric cylinder 235 drives the lifting pressure frame 232 to rise, and the lifting assembly 22 moves downwards to place the second fixture back onto the double belt conveyor line 21.

[0035] In the above design, the structural design and specific implementation of the clamping component 23 can effectively apply precise pressure to the product in the second fixture, ensuring that the product will not shake when the screws are tightened because it is clamped by the clamping mechanism, and also avoiding excessive squeezing of the product and causing damage.

[0036] Specifically: such as Figure 1 As shown, the feeding mechanism 3 includes a No. 3 seat 31 mounted on the frame 1, a No. 3 linear module A32 mounted on the No. 3 seat 31 along the Y-axis, a No. 3 linear module B33 mounted on the output end of the No. 3 linear module A32 along the X-axis, a No. 3 linear module C34 mounted on the No. 3 linear module B33 along the Z-axis, and a pickup component 35 mounted on the output end of the No. 3 linear module C34.

[0037] In actual use, linear module B33 is driven by linear module A32 to move along the Y-axis, linear module C34 is driven by linear module B33 to move the pickup component 35 along the X-axis, and linear module C34 drives the pickup component 35 to rise and fall, so that the pickup component 35 picks up the product in fixture 1 and moves it above fixture 2. Then the pickup component 35 descends and places the product in fixture 2.

[0038] In the above design, the structural design and specific implementation of the feeding mechanism 3 can effectively realize the transfer of products.

[0039] Specifically: such as Figure 3 As shown, the pickup assembly 35 includes a lifting plate 351 disposed at the output end of the third linear module C34, a third slide cylinder 352 vertically disposed on the lifting plate 351, a connecting frame 353 disposed at the output end of the third slide cylinder 352, a rotating platform 354 disposed on the connecting frame 353, a fixing frame 355 disposed on the mounting part of the rotating platform 354, a connecting plate 356 bolted to the lower end face of the fixing frame 355, and a plurality of suction cups 357 disposed on the connecting plate 356.

[0040] In actual use, when it is necessary to adsorb the product in the No. 1 fixture, the No. 3 linear module C34 drives the lifting plate 351 to move down, so that the lifting plate 351 drives the No. 3 slide cylinder 352, the connecting frame 353, the rotating platform 354, the fixed frame 355, the connecting plate 356, and the suction cup 357 to move down synchronously. Then, the No. 3 slide cylinder 352 drives the connecting frame 353, the rotating platform 354, the fixed frame 355, the connecting plate 356, and the suction cup 357 to move down, so that the suction cup 357 adsorbs the product in the No. 1 fixture. Then, the No. 3 slide cylinder 352 and the No. 3 linear module C34 reset, completing the product pickup. When the product needs to be placed in fixture number two, linear module number three C34 drives the lifting plate 351 to move down. The rotary cylinder drives the fixing frame 355, connecting plate 356 and suction cup 357 to rotate to an angle that can be placed in fixture number two. This causes the lifting plate 351 to drive the sliding cylinder 352, connecting frame 353, rotary platform 354, fixing frame 355, connecting plate 356 and suction cup 357 to move down synchronously. Then the sliding cylinder 352 drives the connecting frame 353, rotary platform 354, fixing frame 355, connecting plate 356 and suction cup 357 to move down, so that the suction cup 357 places the product in fixture number one.

[0041] In the above design, the structural design and specific implementation of the pickup component 35 can effectively achieve the adsorption and placement of the product.

[0042] Specifically: such as Figure 5 As shown, the screw-locking mechanism 5 includes a No. 5 base 51 mounted on the frame 1, a No. 5 linear module A52 mounted on the No. 5 base 51 along the Y-axis, a No. 5 linear module B53 mounted at the output end of the No. 5 linear module A52 along the X-axis, a connecting frame 55 mounted at the output end of the No. 5 linear module C54 along the Z-axis, a screw-locking gun 56 mounted on the connecting frame 55, and a CCD camera 57.

[0043] In actual use, linear module A52 drives linear module B53 to move along the Y-axis, and linear module B53 drives linear module C54 to move along the X-axis, causing CCD camera 57 to move above the product for image positioning. After CCD camera 57 has taken the image and positioned, linear module A52 drives linear module B53 to move along the Y-axis, and linear module B53 drives linear module C54 to move along the X-axis, causing screwdriver 56 to move to the screw-locking position. Then, linear module C54 drives connecting frame 55 to lower screwdriver 56, allowing screwdriver 56 to lock the screws pre-installed on the product.

[0044] In the above design, the structural design and specific implementation of the screw-locking mechanism 5 can effectively realize the product's photographic positioning and screw-locking.

[0045] In further detail, it should be understood that the above description is only a specific embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
