Description

Screw-locking equipment and screw-locking system including the same

The present invention relates to a locking device, in particular to a screw locking device and a screw locking system including the same.

During the assembly process of the mechanism, work involving screw locking is required. In order to meet the needs of mass production, the relevant industry began to use automatic screw locking equipment. However, the existing automatic screw locking devices have various disadvantages.

For example, there is currently a method of conveying screws by air pressure, which pushes the required screws through the air pipe to the screwdriver bit of an electric screwdriver (electric screwdriver, or "electric screwdriver"). "Electric Bit"), then use the electric screwdriver to drive the screwdriver to push and tighten the screw into the lock hole of the product. However, this method is only suitable for screws with a specific shape, otherwise the screws are easily turned over and stuck when being transported in the trachea. In addition, when different screws are to be used, the corresponding air pipes and related connecting mechanisms must be replaced, but this involves tedious operations such as pipe disassembly and assembly, which is not conducive to the improvement of production capacity.

At present, there is also a method of sucking screws by vacuum, which sets a screwdriver in a vacuum sleeve, and uses the method of creating negative pressure at the end of the screwdriver to pick up the required screws. However, in order to maintain the vacuum degree of the vacuum sleeve, it is usually only suitable for picking up screws with a relatively flat head. Otherwise, there is a gap between the screw and the vacuum sleeve, which may cause air leakage, resulting in insufficient adsorption force. It can be seen that this approach is only applicable to screws of a specific shape. In addition, the vacuum sleeve can only pick up one screw at a time, so after each screw is locked, it needs to pick up the screw again, which is difficult to meet the requirement of high efficiency. In addition, in order to provide vacuum suction, the vacuum sleeve also needs to be normally connected to the negative pressure pipeline, but the existence of the pipeline greatly limits the freedom of movement of the overall device.

From the foregoing, it can be seen that the conventional screw locking equipment still needs to be improved in terms of screw versatility and productivity improvement.

In view of this, one of the objectives of the present invention is to provide a screw locking device and a screw locking system including the same, so as to solve the aforesaid problems while realizing various screw configurations and effectively improving production capacity.

According to an embodiment of the present invention, a screw locking device is disclosed, which is suitable for picking up a plurality of screws and includes a mounting seat, a carrying plate, a plurality of locking mechanisms and a driving rod. The carrier plate is rotatably arranged on the mounting seat to rotate relative to the mounting seat around an axis. The locking mechanism is removably penetrated through the carrier plate and is spaced around the axis. The end of the locking mechanism is suitable for attracting screws. The rod is actuated to perform a spin motion. The carrier plate drives the locking mechanism to rotate around the axis, so that one of the locking mechanisms is aligned with the driving rod.

A screw locking system disclosed according to an embodiment of the present invention includes a mechanical arm and a screw locking device. The screw locking device includes a mounting seat, a carrying plate, a plurality of locking mechanisms and a driving rod. The mounting base is connected to the robotic arm. The carrier plate is rotatably arranged on the mounting seat to rotate relative to the mounting seat around an axis. The locking mechanism is removably passed through the carrier plate and is spaced around the axis. The end of the locking mechanism is suitable for attracting a screw. The rod is actuated to perform a spin motion. The carrier plate drives the locking mechanism to rotate around the axis, so that one of the locking mechanisms is aligned with the driving rod.

According to the screw locking device and screw locking system disclosed in the aforementioned embodiments of the present invention, since a plurality of locking mechanisms capable of attracting screws are provided on the carrier plate, the screw locking device can pick up a certain number of the same type or screw at one time. Different types of screws can reduce the number of picking up screws under the same workload, help to improve the overall work efficiency, and thus meet the needs of increasing production capacity.

In addition, the locking mechanism may need to be driven by the carrier plate to rotate around the axis to align with the driving rod to perform the next screw locking operation. Therefore, the screw locking device does not need to be involved when switching between different applications or using different screws. The disassembly, replacement or change of any mechanism can be carried out continuously, which helps to greatly shorten the preparation time for switching between different applications or work items.

Therefore, the screw locking device and screw locking system disclosed in the aforementioned embodiments of the present invention can be at least suitable for applications where a single product needs to be locked with a variety of different screws, and/or for a variety of different types of screws that need to be locked. The application of the product has a wide and flexible application.

The screws 91 to 93 may refer to, but are not limited to, screws with different configurations, contours or sizes of heads and/or threads, but the present invention is not limited thereto. In addition, it should be noted that the quantity of the feeding tray 81 and the arrangement and quantity of the screws that can be prepared thereon can be adjusted according to actual needs, and the present invention is not limited to this.

Hereinafter, please refer to FIGS. 2 to 5 further to describe the screw locking device 1 . In order to keep the drawings concise, these drawings may omit the aforementioned robot arm RA, machine vision device 6, pressing device 7, feeding table 8 and object to be locked W. In addition, for the convenience of explanation, the drawings may be described with the screw 91 picked up.

In this embodiment, the screw locking device 1 may include a mounting seat 11 , a first driving device 12 , a carrying plate 13 , at least one locking mechanism 14 , a second driving device 15 , a driving rod 16 , and A transmission member 17 . The mounting seat 11 can be used for connecting the aforementioned robot arm RA and for assembling and disposing of the preceding components. Specifically, the mounting base 11 may include a bottom plate 110 , an arm connecting portion 111 and a fixing frame 112 . The arm connecting portion 111 and the fixing frame 112 can be detachably assembled and fixed on the base plate 110 in any suitable manner. The arm connecting portion 111 can be used for detachably connecting to the aforementioned robot arm RA. The fixing frame 112 can be, but is not limited to, a single-piece structure assembled from multiple components or integrally formed, and can substantially surround an accommodating space (not numbered) for accommodating the first driving device 12 . The first driving device 12 can be, but is not limited to, any suitable motor that can run stably and smoothly at a constant speed, such as a servo motor, which has the effect of precisely controlling the speed and position of the driven object. The first driving device 12 can have a transmission shaft 121 , and the aforementioned transmission member 17 can be fixed to the transmission shaft 121 in any suitable manner to output the power of the first driving device 12 . The transmission member 17 can be, but not limited to, a gear.

The carrier plate 13 is rotatably disposed on the bottom plate 110 of the mounting base 11 and is connected to the transmission member 17 . As shown in the figure, the first driving device 12 can link the carrier plate 13 via the transmission member 17 to drive the carrier plate 13 to rotate relative to the mounting base 11 with an axis AX. Specifically, the carrier plate 13 may include an assembly portion 131 and a transmission portion 132 . The transmission portion 132 may be, but is not limited to, a disk-shaped structure that can be assembled and fixed to the bottom plate 110 of the mounting base 11 in any suitable manner. The assembling part 131 can be fixed on the transmission part 132 in any suitable manner to move with the transmission part 132 , and the assembling part 131 can be, but not limited to, a gear suitable for engaging and interlocking with the transmission member 17 . As shown in the figure, the assembly part 131 can be, for example, a thin gear. In this way, the first driving device 12 can drive the carrier plate 13 by means of the transmission element 17 engaging the assembling portion 131 . It can be understood that, since the transmission member 17 and the carrier plate 13 are in the form of gear meshing, it is helpful to realize high-efficiency, high-precision positioning and high-stability transmission.

In addition, the position where the transmission member 17 engages or engages with the carrier plate 13 is substantially located in the fixed frame 112 , or in other words, between the fixed frame 112 and the bottom plate 110 , so that accidents caused by accidental touch by human hands can be avoided. . However, it should be noted that the present invention is not limited to the manner of engagement between the transmission member 17 and the carrier plate 13 ; for example, in other embodiments, the transmission member and the carrier plate can also be linked to each other by a transmission belt. In addition, the present invention is not limited to the carrier plate 13 shown in the figure; for example, in other embodiments, the carrier plate can also be an integrally formed single-piece gear.

In addition, in order to stabilize the movement of the bearing plate 13, the screw-locking device 1 may further include a bearing B1. Bearing B1 can be, but is not limited to, any suitable bearing, such as a low profile crossed ball bearing. The transmission portion 132 of the carrier plate 13 is rotatably penetrated through the bearing B1, so as to be restricted by the bearing B1 to achieve stable and high-precision rotational movement.

In addition, the carrier plate 13 may have a plurality of through holes 130 arranged at intervals around the axis AX and passing through the assembly part 131 and the transmission part 132 , which may be used for the locking mechanism 14 to be removably passed through. Under this configuration, the carrier plate 13 can be driven by the transmission member 17 to make the locking mechanism 14 rotate around the axis AX. It is explained here that the numbers of the through holes 130 and the locking mechanisms 14 can be adjusted according to actual needs, and the present invention is not limited to this.

The locking mechanism 14 described herein can be, but is not limited to, any suitable mechanism suitable for picking up or picking up screws. For example, as shown in FIG. 5 , the locking mechanism 14 can accommodate a screwdriver bit 141 and a magnet 143 which can be inserted through the end of the screwdriver 141 and is suitable for magnetically attracting screws (as shown in the figure). screw 91). Therefore, when the end of the locking mechanism 14 is pushed and rotated by the driving rod 16 , the screwdriver 141 can be driven to push and rotate the screw 91 attracted by the magnet 143 .

The second driving device 15 can be, but is not limited to, any suitable electric screwdriver (also referred to as "electric screwdriver" or "electric screwdriver"), which is used to realize the related actions of tightening and loosening screws, bolts or screws of power tools. The second driving device 15 can be movably disposed on the fixing frame 112 of the mounting base 11 along a direction substantially parallel to the axis AX. Specifically, the screw locking device 1 may further include a sliding rail 19, at least one sliding block 20 and a sliding seat 21. The sliding rail 19 may be assembled and fixed to one side of the fixed frame 112 in any suitable manner, and the sliding block 20 may be The sliding seat 21 is slidably arranged on the sliding rail 19, and is guided by the sliding rail 19 to slide in a direction substantially parallel to the axis AX. 19 to slide in a direction substantially parallel to the axis AX, the second driving device 15 can be assembled and fixed to the sliding seat 21 in any suitable manner, so as to be able to move along the direction substantially parallel to the axis AX together with the sliding seat 21 The locking mechanism 14 on the carrier plate 13 is relatively close or far away. The number of the sliding blocks 20 can be, but is not limited to, multiple, which helps to provide the required precision and rigidity for sliding the sliding seat 21 .

One end of the driving rod 16 can be assembled with a chuck (not numbered) fixed to the end of the second driving device 15 in any suitable manner, so as to be substantially parallel to the second driving device 15 along with the second driving device 15. The direction of the axis AX is relatively close to or away from the locking mechanism 14 on the carrier plate 13 , and can be driven by the second driving device 15 to spin. Thereby, the driving rod 16 can be inserted into one end of the corresponding one of the locking mechanisms 14 and rotated, thereby pushing and rotating the screws picked up by the locking mechanism 14 through the locking mechanism 14 .

Looking further, the screw locking device 1 may further include a third driving device 22 , at least one cylinder 24 , a pushed block 25 and at least one elastic member 23 . The third drive device 22 can be, but is not limited to, any suitable cylinder that can reciprocate the driven object. The third driving device 22 can be assembled and fixed on the fixed frame 112 in any suitable manner, and can have a driving shaft 221 that can reciprocate in a direction substantially parallel to the axis AX. The column body 24 may be a columnar structure fixed to the sliding seat 21 and extending in a direction substantially parallel to the axis AX. The pushed block 25 is sleeved on one end of the column body 24 relatively far away from the sliding seat 21 . The elastic member 23 can be, but is not limited to, any suitable compression spring, which can be sleeved on the cylinder 24 and sandwiched between the pushed block 25 and the sliding seat 21 . The end of the driving shaft 221 of the third driving device 22 can be connected and fixed to the pushed block 25 in any suitable manner, so as to drive the pushed block 25 through reciprocation, and the sliding seat 21 , the second driving device 15 and the second driving device 15 are connected to the first The driving rod 16 of the two driving devices 15 reciprocates in a direction substantially parallel to the axis AX.

It should be noted here that since the elastic member 23 is sandwiched between the pushed block 25 and the sliding seat 21 , the elastic member 23 can buffer, absorb or weaken the transmission of the third driving device 22 to the transmission through the pushed block 25 to a certain extent. The pushing force of the sliding seat 21 and the second driving device 15 thereon enables the driving rod 16 to drive the locking mechanism 14 with a suitable force, so as to ensure that the force of the locking mechanism 14 pushing and rotating the screw will not damage the object to be locked.

In addition, the screw locking device 1 may further include an oil pressure buffer 26 and a positioning screw 27. The oil pressure buffer 26 and the positioning screw 27 can be arranged on one end of the slide rail 19 in any suitable manner, so as to correspond to The sliding seat 21 is interposed between the sliding seat 21 and the carrier plate 13 . The height of the positioning screw 27 may be slightly lower than the oil pressure buffer 26 . Therefore, when the sliding seat 21 is driven by the third driving device 22 to move in the direction of the carrier plate 13, the hydraulic buffer 26 can first contact the sliding seat 21, thereby buffering, absorbing or weakening the kinetic energy of the sliding seat 21, which also helps In order to achieve the effect of making the driving rod 16 drive the locking mechanism 14 with a suitable force, it is helpful to avoid the problem that the screw locking force is too large and the object to be locked is damaged. Next, the positioning screw 27 can abut the sliding seat 21 to stop the sliding seat 21 from the current position and prevent the driving rod 16 from pressing the locking mechanism 14 excessively, thereby preventing the locking mechanism 14 from pressing the screw excessively to the waiting position. The lock problem occurs. In other words, by adjusting the position or length of the positioning screw 27 , the downward displacement of the sliding seat 21 can be limited, thereby limiting the moving amount of the driving rod 16 pushing the screw through the locking mechanism 14 .

Of course, if the driving force of the third driving device 22 is appropriate and there is no need for buffering, the screw locking device 1 can also omit the aforementioned configuration for buffering the third driving device 22 , but the present invention is not limited to this.

In addition, optionally, the screw locking device 1 may further include a bearing B2, the bearing B2 may be disposed on the sliding seat 21 and through which the driving rod 16 passes, so as to further ensure that the driving rod 16 is substantially parallel to the axis AX. The stability and precision of the directional movement and the rotation around the axis AX are helpful to improve the operation stability and precision of the driving rod 16 locking the screw through the locking mechanism 14 .

On the other hand, optionally, the screw locking device 1 may further include a first sensor S1 , and the mounting base 11 may further include a telescopic extension bracket 113 , as shown in FIG. 4 , the telescopic extension bracket 113 may However, it is not limited to any telescopic mechanism with adjustable length, which can be fixed to one side of the bottom plate 110 relative to the fixed frame 112 in any suitable manner, and the telescopic extension bracket 113 can be extended along the direction substantially parallel to the axis AX. Telescopic, the first sensor S1 can be, but is not limited to, any suitable light sensor, which can be disposed at the end of the telescopic extension bracket 113 to correspond to the end of the locking mechanism 14 , so as to detect the end of the locking mechanism 14 Whether there are any screws (screws 91 as shown in the picture).

In addition, optionally, the screw locking device 1 may further include a second sensor S2, and the mounting base 11 may further include a sensing sheet 115. The second sensor S2 may be, but not limited to, any suitable light sensor The measuring device can be arranged on the side of the telescopic extension bracket 113 facing the locking mechanism 14, and the sensing plate 115 can be arranged under the carrier plate 13 and has at least a part of it extending outward in the radial direction, but not limited to. In this way, the sensing sheet 115 can pass through the sensing area of the second sensor S2 with the rotation of the carrier plate 13 , so that the second sensor S2 can know the carrier disk 13 by sensing the sensing sheet 115 . Whether to return to the origin or the predetermined position.

Next, please refer to FIGS. 6A to 6B and 7 in conjunction with the above-mentioned drawings to illustrate how the screw locking system 2 enables the screw locking device 1 to pick up the screws. Prior to this, the feeding tray 81 may have pre-arranged the screws 91 to 93 in a manner corresponding to the locking mechanism 14, and the locking mechanism 14 may be, for example, through the aforementioned carrier plate 13 and the second sensor S2 and the sensor sheet. The cooperation of 115 turns to positioning and corresponds to the screws 91-93 on the feeding tray 81, respectively. Then or at the same time, the screw locking device 1 can be moved to one of the feeding trays 81 of the feeding table 8 by the robot arm RA, and then, the mounting base 11 can be driven by the robot arm RA to approach the feeder along the axis AX direction, for example. The material tray 81 (as shown by the arrow in FIG. 6A ) enables the locking mechanism 14 to pick up or pick up the screws 91 to 93 at the corresponding positions, respectively. Next, the robotic arm RA can move the mounting base 11 away from the feeding tray 81 , so that the locking mechanism 14 together with the screws 91 to 93 at its ends are moved away from the feeding tray 81 (as shown by the arrows in FIG. 6B ).

At this time, as shown in FIG. 7 , the locking mechanism 14 can make the first sensor S1 confirm whether the screws 91 to 93 are adsorbed on the locking mechanism 14 by rotating the carrier plate 13 once. At that time, the work of picking up the screws 91 to 93 by the screw locking device 1 is completed, and the work of screw locking can be continued. It should be added that, after the screw locking device 1 confirms the pick-up of the screws 91 to 93 by the first sensor S1, the screw locking device 1 can, but is not limited to, use the carrier plate 13 and the aforementioned second sensing The cooperation of the sensor S2 and the sensing piece 115 rotates and resets the locking mechanism 14 to a predetermined position.

Here, please refer to FIGS. 8A-8B together with the aforementioned FIG. 1 to illustrate how the screw locking system 2 enables the screw locking device 1 to lock the screw to the object W to be locked. For the convenience of description, the operation of locking the screw 91 to one of the locking holes H of the object to be locked W is described below as an example.

First, the carrier plate 13 can be driven by the first driving device 12 and the transmission member 17 to rotate one of the locking mechanisms 14 with the screws 91 adsorbed to the position corresponding to the driving rod 16 (as shown by the arrow). Next or before, the screw locking device 1 can be moved by the mechanical arm RA to a position where the locking mechanism 14 corresponding to the driving rod 16 is aligned with one of the locking holes H of the object W to be locked. And, optionally, when the screw locking device 1 aligns the screw 91 to be locked with the locking hole H, the pressing device 7 can extend downward as shown by the arrow to press against the object W to be locked.

Next, the third driving device 22 operates to drive the sliding seat 21 and the second driving device 15 thereon to the carrier plate 13 in a direction substantially parallel to the axis AX (as shown by the arrow), thereby driving the driving rod 16 to the carrier plate 13 . The end is inserted into the corresponding locking mechanism 14 to push and tighten the screw 91 to the object W to be locked by the locking mechanism 14 .

During the process, it can be understood that, since the elastic member 23 is sandwiched between the pushed block 25 and the sliding seat 21, and the hydraulic buffer 26 is disposed at one end of the sliding rail 19 and corresponds to the sliding seat 21, it can buffer or Absorb the thrust force transmitted by the third driving device 22 to the sliding seat 21 and the second driving device 15 thereon via the pushed block 25 , so that the driving rod 16 drives the locking mechanism 14 with a suitable force, thereby ensuring that the locking mechanism 14 pushes And the force of turning the screw 91 is enough to lock the screw 91 without damaging the object W to be locked. In addition, since the positioning screw 27 slightly shorter than the hydraulic buffer 26 is also arranged on one end of the sliding rail 19 and corresponds to the sliding seat 21 , it can stop the sliding seat 21 in a proper position and prevent the driving rod 16 from being pushed down excessively. The locking mechanism 14 can avoid the problem that the locking mechanism 14 pushes the screw 91 against the object W to be locked excessively.

It can be understood that the screws 91 to 93 on the other locking mechanisms 14 can be locked to other locking holes H of the object to be locked W or other objects to be locked similar to the aforementioned operations. In addition, after the set locking work is completed, the screw locking device 1 can use the first sensor S1 to detect whether the locking mechanism 14 has any remaining screws on the locking mechanism 14 by detecting the rotation of the locking mechanism 14 on the carrier plate 13 . In order to confirm whether the set locking work is completed.

From this, it can be seen that the screw locking device of the aforementioned embodiments of the present invention is versatile for different types of screws, and thus can be at least suitable for applications where a single product needs to be locked with a variety of different screws, and/or suitable for different types of screws. The application of a variety of different products, so it has a wide and flexible application. In addition, because the screw locking device of the present embodiment can pick up a certain number of screws of the same type or different types at one time, the number of picking up screws under the same workload can be reduced, which is helpful to improve the overall work efficiency, thereby improving productivity. demand. In addition, it can be understood that the screw locking device of this embodiment does not involve any operations such as disassembly, replacement or change of any mechanism when switching between different applications or using different screws, and can be carried out continuously, which is helpful to greatly shorten the time difference. Switch preparation time between applications or work items.

Although the present invention is disclosed in the foregoing embodiments, it is not intended to limit the present invention.
