Description

Technical Field

[0001] This invention relates to the field of fully automatic screw-driving machines, and more specifically to a fully automatic screw-driving machine. Background Technology

[0002] A fully automatic screw-driving machine, also known as an automatic screw fastening machine, automatic screw feeding and tightening machine, or automatic screw driving machine, is a type of mechanical equipment used for automatically assembling screws. It uses an electric drive unit and an automatic control system to automatically feed, identify, and tighten screws, greatly improving production efficiency.

[0003] Fully automatic screw driving machines are mainly divided into two categories: desktop and multi-axis models. Desktop fully automatic screw driving machines (also known as XY-TABLE automatic screw driving machines) are usually customized according to the customer's actual needs, including the strokes of the X, Y, and Z axes and the number of Z axes. Their feeding methods generally include suction feeding and pneumatic feeding, with the choice depending on whether the screw specifications meet the requirements of pneumatic feeding. Multi-axis fully automatic screw driving machines are more focused on specialized screw driving for specific products, and their feeding methods include manual feeding, pneumatic feeding, and suction feeding.

[0004] Existing fully automatic screw-driving machines use a rotating disc to move materials through multiple screw-driving modules. The finished screws are then scattered in a collection bin, requiring staff to count them one by one, which is inconvenient. Summary of the Invention

[0005] To address the aforementioned problems, this invention proposes a fully automatic screw-driving machine. This solves the shortcomings of existing fully automatic screw-driving machines, which use a rotating disc to move materials sequentially through multiple screw-driving modules. The finished screws are then scattered and piled haphazardly in a collection bin, requiring manual counting by staff, which is inconvenient.

[0022] Beneficial effects

[0023] 1. This invention drives a rotating disk to rotate via a drive motor. The vibrating screen aligns the workpiece to be processed and moves it to one side of the feeding module. The first transfer module moves the workpiece to be processed onto the rotating disk. As the rotating disk rotates, the workpiece passes through the first screw-driving module, the second screw-driving module, the detection module, and the discharge module in sequence. The automatic aligning and discharging component is used to align and discharge the material, making it convenient to count the quantity. There is no need for staff to count the materials one by one when they are scattered and piled up in the collection cylinder.

[0024] 2. In this invention, when the micro switch is triggered, the control module receives the electrical signal from the micro switch and controls the air pump to work for a period of time (tens of seconds), pushing a pair of pistons to move to both sides. On one side, the piston pushes the ball back into the upper straight tube, and on the other side, it pushes the second push rod and the second straight rack to move, thereby pushing the limiting plate to rotate from the first working position to the second working position. Since the limiting plate is configured to block the finished product material with the screw driven in when it is in the first working position, and to allow the finished product material with the screw driven in to fall into the storage box when it is in the second working position, the finished product material with the screw driven in is allowed to fall into the storage box, thus completing the quantitative storage.

[0035] The specific embodiments of the present invention will be described in further detail below with reference to the accompanying drawings and examples. The following examples are used to illustrate the present invention, but are not intended to limit the scope of the invention.

Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.

[0037] Example 1

[0038] The technical solution adopted in this invention is as follows:

[0039] like Figure 1 As shown, this invention discloses a fully automatic screw-driving machine, comprising: a machine body 1, a feeding module 2, a rotating disk 3, a first screw-driving module 4, a second screw-driving module 5, a discharge module 6, and a detection module 7; the feeding module is installed on one side of the machine body, and a first moving module 8 is installed at the end of the feeding module; the rotating disk is installed on the top of the machine body, and a drive motor 9 is externally connected to the rotating disk to drive the rotating disk to rotate; the first screw-driving module is installed on the side of the rotating disk close to the feeding module; the second screw-driving module is installed on the side of the first screw-driving module away from the feeding module; a second transfer module 10 is installed on the discharge module, and an automatic leveling and discharging component 11 is installed at the end of the second transfer module; the automatic leveling and discharging component is used to level and discharge the material. The detection module is installed between the second screw-driving module and the discharge module, and a control module 50 is externally connected to the detection module. The feeding module includes at least two sets of vibrating screens 12, which are used to convey the workpiece to be processed. A storage box 13 is provided at the end of the discharge module.

[0040] The control unit of this invention uses a computer system or a PLC (Programmable Logic Controller).

[0041] In this embodiment, the drive motor drives the rotating disk to rotate, and the vibrating screen moves the workpiece to be processed to one side of the feeding module after it is shaped. The first transfer module moves the workpiece to be processed onto the rotating disk. As the rotating disk rotates, the workpiece to be processed passes through the first screw-driving module, the second screw-driving module, the detection module and the discharge module in sequence. The automatic shaped material feeding component is used to shape the material and release it.

[0042] Example 2

[0043] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6 As shown, the difference between Embodiment 2 and Embodiment 1 is that the automatic straightening and feeding assembly includes a guide chute 14; the guide chute is equipped with multiple dividing plates 15, which divide the guide chute into multiple independent feeding channels 16. The bottom plate in the middle of the feeding channel is provided with a through hole 17, and a first rotating roller 18 is installed in the through hole. The first rotating roller is evenly provided with first gear teeth 19. Below the first rotating roller is a first straight rack 20 that meshes with the first rotating roller. The end of the first straight rack is provided with a first push rod 21, and the end of the first push rod is provided with a first contact head 22. Both ends of the first rotating roller are rotatably inserted into the guide chute and the dividing plates.

[0044] A second rotating roller 23 is mounted on the bottom plate of the feeding channel. The lower half of the second rotating roller is evenly provided with second gear teeth 24 at both ends. A second straight rack 25 that meshes with the second rotating roller is provided below the second rotating roller. A second push rod 28 is provided at the end of the second straight rack. A limiting plate 26 is provided in the middle of the upper half of the second rotating roller. The two ends of the second rotating roller are rotatably inserted into the guide chute and the dividing plate. The limiting plate is configured to block the finished material with screws driven in when it is in the first working position, and allow the finished material with screws driven in to fall into the storage box when it is in the second working position.

[0045] It should be noted that the limiting plate in this embodiment is a straight plate structure.

[0046] The automatic leveling and feeding assembly also includes a transmission structure 27, which comprises an upper straight pipe 30, a bent pipe 31, and a lower straight pipe 32. A first rotating roller is inserted into the upper straight pipe, and a second rotating roller is inserted into the other end of the lower straight pipe. The lower straight pipe is equipped with a pair of pistons 33, with an elastic element 34 connecting them. An air outlet pipe is located at the top of the lower straight pipe between the pistons, and an air inlet pipe 36 is located at the bottom of the lower straight pipe between the pistons. An air pump 37 is located at the end of the air inlet pipe. A second push rod connects to one piston of the lower straight pipe. A ball bearing 39 is filled between the other piston, which is away from the second push rod, and the first push rod. A microswitch 38 is located in the middle of the lower straight pipe between the pistons. The microswitch is electrically connected to a control module, which is electrically connected to the air pump. When the microswitch is triggered, the control module receives the electrical signal from the microswitch and controls the air pump to operate for a period of time, pushing the pistons to move to both sides. An air outlet pipe 29 is located at the top of the lower straight pipe between the pistons.

[0047] In this embodiment, the finished product with screws falls into the feeding channel, passes through the first rotating roller, and drives the gear teeth and the first rotating roller to rotate; pushes the rack to move upward for the first time, causing the first push rod to insert into the upper straight tube and push the ball of the upper straight tube to move, and drives the other ball to move downward to push the piston to move downward; when the number of finished products with screws falling reaches a predetermined number, the piston moves downward until the micro switch is triggered.

[0048] When the microswitch is triggered, the control module receives the electrical signal from the microswitch and controls the air pump to operate for a period of time (tens of seconds). This pushes a pair of pistons to move to both sides. One piston pushes the ball bearings back into the upper straight tube, while the other pushes the second push rod and the second rack, thereby rotating the limit plate from the first working position to the second working position. The limit plate is configured to block the finished product material with the screws driven in when it is in the first working position, but allows it to fall into the storage box when it is in the second working position. This allows the finished product material with the screws to fall into the storage box, completing the quantitative storage. During this period, the control module controls the drive motor to stop working, causing the rotating disk to stop rotating.

[0049] When the material is discharged and the air pump stops working, the excess gas is discharged through the air outlet pipe. On the one hand, the elastic element causes the second straight rack to return to its original position, causing the second limit plate to rotate from the second working position to the first working position. On the other hand, the piston pushes the ball into the upper straight pipe, causing the ball to return to its initial state.

[0050] Example 3

[0051] The difference between Example 3 and Example 2 is that, as Figure 3 As shown, the bend is bent 180° and its movement is unimpeded.

[0052] Example 4

[0053] The difference between Example 3 and Example 2 is that, as Figure 7 and Figure 8 As shown, the limiting plate in this embodiment is an obtuse-angled triangle. After rotation, it changes from an upright state to a flat state. Second straight toothed racks are provided on the lower sides of both ends of the second rotating roller.

[0054] The above description is merely a preferred embodiment of the present invention and does not limit the scope of patent protection of the present invention. Any equivalent structural transformations made based on the description and drawings of the present invention, whether directly or indirectly applied to other related technical fields, are similarly included within the scope of protection of the present invention.
