Description

Technical Field

[0001] This utility model relates to the field of screw fixing technology, and in particular to an automated screw-driving device. Background Technology

[0002] Screw-driving equipment is a type of mechanical equipment used for automated screw tightening, and it is widely used in manufacturing, electronic assembly, automotive industry and other fields.

[0003] The existing equipment uses a balance arm to support and fix the screw gun. It requires manual pulling of the screw gun on the balance arm to complete the tightening of three screws in sequence, which is time-consuming and laborious. In addition, the screw gun has a sleeve-type head when screwing. When the screw falls into the positioning sleeve, the screw will be skewed to a certain extent. The screw is not driven vertically into the product, which will result in poor screw torque or the screw not being tightened properly even when the torque is reached. Utility Model Content

[0004] The purpose of this invention is to provide an automated screw-driving device that overcomes the shortcomings of the counterbalanced arm fixed screw gun, which requires manual screw-driving and the sleeve-type gun head, which can easily cause the screw to be misaligned, resulting in poor screw torque.

[0005] To achieve the above objectives, an automated screw-driving device is provided, comprising a main body block, a support plate fixedly connected inside the main body block, a transport line fixedly connected to the upper side of the support plate, two transport lines being provided, an adjustment structure being provided on the outer side of the support plate, a three-axis servo module fixedly connected to the upper side inside the main body block, and a screw gun fixedly connected to the outer side of the three-axis servo module.

[0006] The adjustment structure includes a hydraulic rod, the output end of which passes through a support plate and is fixedly connected to a lifting plate. This allows the device to replace manual operation of the balance arm, saving time and effort, and providing convenience and speed.

[0007] According to the aforementioned automated screw-driving device, a blocking cylinder is fixedly connected to the right side of the left-side conveyor line. This is to prevent the pallet block moving on the upper side of the adjusting structure.

[0008] According to the aforementioned automated screw-driving equipment, a Z-axis moving module is fixedly connected to the inner side of the main body of the equipment, and a mask fixture is fixedly connected to the outer side of the Z-axis moving module. A sleeve is provided inside the mask fixture; the function of the sleeve is to prevent the screws removed during reverse unscrewing from falling into the product.

[0009] According to the aforementioned automated screw-driving device, a pin block is fixedly connected to the upper side of the lifting plate, and two pin blocks are provided. This facilitates the positioning of the plate.

[0010] According to the aforementioned automated screw-driving device, the screwdriver head is configured with a three-lobed nozzle. This facilitates securing the screw and prevents it from becoming misaligned.

[0011] This utility model has the following beneficial effects: Compared with the prior art, the setting of the adjustment structure, blocking cylinder, three-axis servo module, mask tooling, and Z-axis moving module allows the device to replace manual operation of the screw gun on the balance arm when screwing, saving time and effort, and making it convenient and quick. At the same time, the sleeve on the mask tooling helps to prevent the screws from falling into the product when they are removed in reverse. Attached Figure Description

[0017] This section will describe in detail the specific embodiments of the present utility model. The preferred embodiments of the present utility model are shown in the accompanying drawings. The purpose of the drawings is to supplement the textual description with graphics, so that people can intuitively and vividly understand each technical feature and the overall technical solution of the present utility model, but they should not be construed as limiting the scope of protection of the present utility model.

[0018] Reference Figure 1-2 This utility model discloses an automated screw-driving device, which includes a main body block 1. A support plate 8 is fixedly connected inside the main body block 1. A transport line 2 is fixedly connected to the upper side of the support plate 8. There are two transport lines 2. An adjustment structure 3 is provided on the outer side of the support plate 8. A three-axis servo module 5 is fixedly connected to the upper side inside the main body block 1. A screw gun 6 is fixedly connected to the outer side of the three-axis servo module 5. A blocking cylinder 4 is fixedly connected to the right side of the left transport line 2. A Z-axis moving module 9 is fixedly connected to the inner side of the main body block 1. A mask fixture 7 is fixedly connected to the outer side of the Z-axis moving module 9. The screw gun 6 has a three-lobed nozzle.

[0019] The adjustment structure 3 includes a hydraulic rod 301. The output end of the hydraulic rod 301 passes through the support plate 8 and is fixedly connected to a lifting plate 302. A pin block 303 is fixedly connected to the upper side of the lifting plate 302. There are two pin blocks 303.

[0020] The PLC controller is electrically connected to the transport line 2, hydraulic rod 301, blocking cylinder 4, three-axis servo module 5, screw gun 6, mask fixture 7, and Z-axis movement module 9, facilitating the operation of the control components. When it is necessary to fix the pallet and adjust its height, the operator activates the hydraulic rod 301, which moves the lifting plate 302. The pin block 303 on the upper side of the lifting plate 302 slides into the positioning hole of the pallet, preventing the pallet from sliding off the upper side of the lifting plate 302. Then, the three-axis servo module 5 is activated to drive the screws with the screw gun 6. By adjusting the settings of structure 3, blocking cylinder 4, three-axis servo module 5, mask fixture 7, and Z-axis movement module 9, the device can replace manual operation of the screw gun 6 on the balance arm when driving screws, saving time and effort, and making it convenient and quick. At the same time, the sleeve on the mask fixture 7 prevents the screws from falling into the product when they are removed in reverse.

[0021] Working principle: Before screwing in the product, the operator first fixes the product to a pallet, then transports the pallet with the product on conveyor line 2. Next, the blocking cylinder 4 is activated, ultimately stopping the pallet from moving further. Then, the adjusting mechanism 3 is activated to move the pallet with the product upwards. At this point, the Z-axis moving module 9 is activated, moving the mask fixture 7 to align the sleeve hole on the mask fixture 7 with the hole on the outside of the product where the screw needs to be screwed in. The screw is then placed at the output end of the screwdriver 6. Finally, the equipment activates the three-axis servo module 5. 5. Move the screwdriver 6 along with the screwdriver, and then control the screw to drill holes. During this process, the mask fixture does not completely cover the screw-drilling position; it has a sleeve on it. When drilling, the screwdriver bit passes through the sleeve to lock the screw into the product. The purpose of this sleeve is to prevent the screw from falling into the product when it is removed. The screwdriver 6 has a three-lobed nozzle, which prevents the screw from tilting and avoids situations where the screw torque is insufficient or the screw is not locked in place. After drilling is completed, all mechanisms return to their original positions in sequence, and the blocking cylinder 4 releases the tray, which flows into the next station.

[0022] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
