Thus, a feature defined as "first" or "second" may explicitly or implicitly include at least one such feature. In addition, the technical solutions in the embodiments may be combined with each other, but it must be based on the realization of those skilled in the art, and when the technical solutions are contradictory or cannot be realized, such a combination should be considered to be absent and not within the protection scope of the present invention.
Referring to fig. 1, fig. 1 is a functional block diagram of a first embodiment of a screw locking device according to the present invention; the first embodiment of the screw locking device of the present invention provides a screw locking device, which comprises a detection unit 200, a control unit 100, a screw locking tool assembly 300 and a screw assembly 400, wherein the screw assembly 400 is installed in a screw clamping portion of the screw locking tool assembly 300;
the screw locking tool assembly 300 is used for driving the screw assembly 400 to move;
it is easy to understand that the screw has a very wide variety, such as a hexagon socket countersunk head screw, a round head inner cross screw, a straight flat head screw, etc., referring to fig. 2, fig. 2 is an illustration for facilitating the embodiment of the present invention, and shows several screws that can be used as the screw in the embodiment of the present invention; the screw head groove is the area where the screw rod for locking the screw can be placed in the screw head recess, and it should be noted that part of the screw head is in the shape of outer hexagon and the like. The screw with a concave head is used for illustration in the embodiment, and is not meant to limit the type of screw that the present invention can lock.
It should be noted that the locking screw tool assembly 300 may be an electric locking screw tool such as an electric screwdriver or an electric screwdriver, which can be inserted into the locking screw assembly 400; the screw assembly 400 is a screw assembly 400 that can be used for locking screws, and the types of the screw locking tool assembly 300 and the screw assembly 400 are not limited herein.
The control unit 100 is used for controlling the screw locking tool assembly 300 to descend;
it should be noted that the control unit 100 includes a clamping portion capable of clamping the lock screw tool assembly 300; a moving part which can drive the lock screw component to move. The control unit 100 is connected with the screw locking tool assembly 300 through a control line, the control unit 100 further comprises a control chip, and the control chip can control the movement part to execute corresponding operations so as to drive the screw locking tool to execute up-and-down movement and find the position of the outer hole of the screw. The output end of the control chip is connected with the motion part to control the motion part to drive the screw locking tool assembly 300, and the other output end of the control chip is connected with the screw locking tool assembly 300 to control the rotation mode of the screw locking tool assembly.
The detection unit 200 is used for detecting whether the screw assembly 400 enters the screw outer hole;
it is easy to understand that the hole for installing the screw is called a screw hole, the recess of the head of the screw is called a screw head groove, and the hole higher than the upper edge of the screw hole is called a screw outer hole; in order to prevent unsmooth surface of the part and easy looseness of convex screw heads caused by the protrusion of screws during the installation of the part, the outer holes of the screws on most joint parts are higher than the thickness of the screw heads so as to prevent the convex screws from protruding after the screws are locked. This results in a high screw outer bore that does not align well with the screw head groove when locking the screw, resulting in head groove wear when the screw locking tool assembly 300 drives the screw assembly 400 to rotate at high speed. After the groove on the head of the screw is worn, the operations of locking and loosening the screw cannot be normally carried out.
It should be noted that the detection unit 200 may be a torque switch or a photoelectric switch. When the detection unit 200 is a photoelectric switch, the photoelectric switch detects whether to enter the screw outer hole or not through detecting the position of the screw assembly 400, the photoelectric switch is connected with the control unit 200, the detection result is sent to the control unit 200, and the photoelectric switch can also remind a user whether to enter the screw outer hole or not and whether to enter the screw head groove or not through brightness and darkness. When the detection unit 200 is a torque switch, the torque switch detects the torque state of the screw locking tool assembly 300 and determines whether the screw enters the screw outer hole or not and whether the screw is aligned with the screw head groove.
The control unit 100 is further configured to control the screw locking tool assembly 400 to start when the screw assembly 400 enters the screw outer hole, and control the screw locking tool assembly 300 to drive the screw assembly 400 to rotate according to a first preset condition.
It should be noted that the screw assembly 400 is a magnetic component, and when the screw is an iron screw or a ferrous screw, it has an adsorbability to the screw, and when the screw is aligned, it can automatically close to the screw and clamp the head groove for locking the screw.
Reference is made to fig. 2a, 2b, 2c, 2d, 2e, 2 f; fig. 2a is a top view of a cross screw, fig. 2b is a side view of the cross screw, fig. 2c is a top view of an inner hexagonal screw, fig. 2d is a side view of the inner hexagonal screw, fig. 2e is a top view of a straight screw, and fig. 2f is a side view of the straight screw.
The first preset condition is determined according to a screw rotation opening. Taking a straight screw as an example, one rotation degree of the straight screw is 360 degrees divided by 2, and one rotation degree is 180 degrees; for example, the socket head cap screw has a rotation degree of 360 degrees divided by 6, a rotation degree of 60 degrees, and a cross screw of 90 degrees. The first preset condition is that the screw is rotated at a low speed according to the degree of the screw rotation opening, and the low speed is a first preset speed. The first preset speed is set according to actual conditions, and preferably the setting conditions are as follows: when the screw assembly 400 rotates at the first preset speed, almost no abrasion is caused to the screw head grooving, the first preset speed is not too low, and the automatic screw locking action efficiency is low.
It will be readily appreciated that due to the nature of the screw assembly 400 described above, when the screw assembly 400 is rotated through a rotation opening, if the screw is properly positioned within the screw bore, the screw assembly 400 will align with and jam the screw head groove.
The detection unit 200 is further configured to detect whether the screw assembly 400 is aligned with the screw head grooving or not when the screw assembly 400 rotates;
the control unit 100 is further configured to control the screw locking tool assembly 300 to drive the screw assembly 400 to rotate according to a second preset condition when the screw assembly 400 is aligned with the screw head grooving, so as to lock the screw.
It will be readily appreciated that rotation of the screw assembly 400 detects whether the screw assembly 400 is aligned with the head groove, and that upon alignment of the screw assembly 400, the screw assembly 400 jams the head groove, at which time a screw locking operation can be initiated.
It should be noted that the second preset condition is rapid rotation, and the second preset condition is the screw locking speed in a normal state; the rotation speed in the second preset condition may be set according to actual conditions in consideration of the type of the screw and the loss of the screw thread, the screw hole thread.
The embodiment can be understood in three steps, the action of aligning the screw head grooving is executed when the position of the screw outer hole is searched and aligned, and the screw locking can be started if the screw head grooving is aligned.
Through the arrangement, the groove on the head of the screw is accurately found in the outer hole of the deep screw, and the screw is quickly locked; the screw head grooving machine has the advantages that damage caused by misalignment of the screw rod assembly is effectively prevented, manpower and material resources are saved, the efficiency of mechanical installation is improved, a visual recognition device does not need to be installed, and the automatic screw locking cost is reduced.
Referring to fig. 3, fig. 3 is a schematic structural view of a second embodiment of a screw locking device according to the present invention; based on the first embodiment of the screw locking device of the present invention, a schematic structural diagram of a second embodiment of the screw locking device of the present invention is provided. In this embodiment, the moving part of the control unit 100 is a cylinder 101, the control unit 100 is only partially shown in fig. 3, and fig. 3 does not affect the function of the control unit 100. In fig. 3, the detection unit 200 is a photoelectric switch 201, the screw locking tool assembly 300 is a screwdriver 301, the screw assembly 400 is a hexagonal screw 401, the screw is an inner hexagonal screw 501, and the screw head groove is an inner hexagonal screw head groove 502.
The detection unit 200 is further configured to detect a type of the screw head grooving, and send a type signal to the control unit 100;
it should be noted that, in the present embodiment, the photoelectric switch 201 is configured such that the photoelectric switch 201 can identify the type of the screw assembly 400 when the screw assembly 400 is installed and inform the control unit 100 of the type of the screw head grooving.
It is easily understood that if the type of the screw assembly 400 is known by a user, the type may be directly set by the user, written in the storage unit of the control unit 100, and directly controlled by the control unit 100.
The control unit 100 is further configured to generate a first preset condition according to the type signal, and control the screw locking tool assembly 300 to drive the screw assembly 400 to rotate according to the first preset condition.
It should be noted that in this embodiment, the groove of the screw head is an inner hexagon, and the degree of one rotation opening is 60 degrees, that is, the first preset condition is that the screw assembly 400 is driven to rotate by 60 degrees at the first preset speed. In the case that the screw is correctly placed in the screw hole, the head groove of the screw is aligned in parallel with the upper edge of the screw outer hole, and the screw assembly 400 can be aligned and clamped within a rotation degree.
The control unit 100 is further configured to control the screw locking tool assembly to be lifted up and lowered down again when the screw assembly is not aligned with the screw head grooving;
it will be readily appreciated that if the screw is not properly positioned within the screw bore, the screw head groove is not initially aligned parallel to the upper edge of the screw bore, and the screw assembly 400 is difficult to align. In this case, it is necessary to lift and lower again, and perform the alignment operation again.
The detection unit 200 is further configured to detect whether the screw assembly 400 enters the screw outer hole when the screw locking tool assembly 300 descends again;
it is easy to understand that if the head of the screw assembly 400 is separated from the screw outer hole during the lifting and descending processes, the head may be deviated from the screw outer hole due to mechanical vibration or the like during the descending process, and the detection unit 200 is required to detect the head again in advance. This step may also be omitted if the head of the screw assembly 400 is not removed from the interior of the screw bore.
The control unit is further used for controlling the screw locking tool assembly to drive the screw assembly to rotate according to a first preset condition when the screw assembly enters the screw outer hole.
It is easy to understand that the operation of aligning the screw head groove is performed again when the screw head is lowered again, which is a cyclic operation and will not be described again here.
The control unit 100 is further configured to control the screw locking tool assembly 300 to stop working and alert a user when the number of times that the screw locking tool assembly 300 is lifted and then lowered reaches a preset number of times.
It should be noted that, under the condition that the screw is incorrectly placed in the screw hole, the screw and the screw assembly can be lifted up and then fall down together through the adsorption action of the screw assembly 400 to find the correct position for placing in the screw hole, and the screw can also be assisted by the falling of the screw assembly 400 to place correctly; however, in some cases, the above solutions cannot make the screw placed correctly, and the number of times of lifting and dropping reaches a preset number of times, and a user needs to manually place the screw in the screw hole correctly.
It should be noted that the preset times can be set according to actual conditions, and preferably can be set to be the unit times, so as to speed up the progress of executing the screw locking operation and give an alarm to the user as early as possible, so as to find the problem that the screw is placed askew.
The control unit 100 is further configured to detect the screw state, and control the screw locking tool assembly 300 to stop working when the screw state is a locked state.
It will be readily appreciated that, in the case where the screw has been tightened, the rotation of the screw assembly 400 by the screw-locking tool assembly 300 will feel the resistance reaching a certain threshold; the control unit 100 is connected to the screw locking tool assembly 300, and can detect the operation state of the screw locking tool assembly 300, and when detecting that the resistance reaches a preset threshold, the control unit can know the screw locking and control the screw locking tool assembly 300 to stop working.
It is easy to understand that after the screw is locked, the control unit 100 can control the screw locking tool assembly 300 to be lifted, and control the screw locking tool assembly 300 to move to the next screw, and repeatedly perform all the above actions to realize the mechanical automatic screw locking.
In a specific implementation, the screw locking device is provided with a screw assembly, and the screw assembly can not only perform screw locking operation but also perform screw loosening operation if the screw assembly is controlled to rotate reversely under the condition that the screw assembly is matched with the screw head grooving.
And according to a first preset condition and a second preset condition, reversely rotating the conditions to obtain a first loosened screw preset condition and a second loosened screw preset condition, and performing a loosened screw operation according to the first loosened screw preset condition and the second loosened screw preset condition, wherein the specific control method is the same as that of screw locking.
It is easy to understand that if there is a need to disassemble a component, i.e. there is a need to loosen a screw, the screw locking device of the present invention is also applicable to loosen a screw in a case where the screw outer hole of the component is deep. The control unit 100 may detect whether the screw is locked or not according to resistance received by the screw assembly, and may detect whether the screw is loosened or not according to resistance received by the screw assembly, and control the screw locking tool assembly to stop working when the screw is completely loosened.
It is easy to understand that, in the above embodiments, the screw assembly is a magnetic member, and if the screw is made of iron or contains iron, the screw assembly can attract the screw, take the screw out of the screw outer hole, and facilitate the worker to detach the component. After the screw loosening operation is performed, the control unit can control the screw locking tool assembly to lift up, control the screw locking tool assembly to move to the next screw, and repeatedly perform all the actions so as to achieve mechanical automatic screw loosening.
The embodiment of the invention prevents the problem that the screw locking operation cannot be carried out due to the fact that the screw is not accurately placed in the screw locking action, effectively discovers hidden dangers and gives an alarm to a user, and the device can automatically stop after the screw is locked, thereby preventing the screw head from being abraded by cutting grooves and preventing the screw assembly and the screw locking tool assembly from being damaged due to repeated screw locking.
Referring to fig. 4, fig. 4 is a schematic flow chart illustrating a control method of a screw locking device according to a first embodiment of the present invention;
in addition, in order to achieve the above object, the present invention further provides a method for controlling a screw locking device, the method comprising:
step S100: the control unit controls the screw locking tool assembly to descend;
the control unit includes a clamping portion capable of clamping the lock screw tool assembly; a moving part which can drive the lock screw component to move. The control unit is connected with the screw locking tool assembly through a control line, the control unit further comprises a control chip, and the control chip can control the movement part to execute corresponding operation so as to drive the screw locking tool to execute up-and-down movement and find the operation of the screw outer hole position.
Step S200: the detection unit detects whether the screw assembly enters the screw outer hole or not;
it should be noted that the detection unit may be a torque switch or a photoelectric switch. When the detection unit is a photoelectric switch, the photoelectric switch detects whether to enter the screw outer hole or not through detecting the position of the screw assembly, the photoelectric switch is connected with the control unit, the detection result is sent to the control unit, and the photoelectric switch can also remind a user whether to enter the screw outer hole or not and whether to enter the screw head groove or not through brightness and darkness. When the detection unit is a torque switch, the torque switch detects the torque state of the screw locking tool assembly to judge whether the screw enters the outer hole or not and whether the screw aligns with the screw head groove.
Step S300: the control unit controls the screw locking tool assembly to start when the screw rod assembly enters the screw outer hole, and controls the screw locking tool assembly to drive the screw rod assembly to rotate according to a first preset condition;
it should be noted that the screw rod assembly is a magnetic component, and when the screw is an iron screw or a screw containing iron, the screw is adsorptive, and when the screw is aligned, the screw can be automatically close to and the head groove can be clamped so as to lock the screw.
The first preset condition is determined according to a screw rotation opening. Taking a straight screw as an example, one rotation degree of the straight screw is 360 degrees divided by 2, and one rotation degree is 180 degrees; for example, the socket head cap screw has a rotation degree of 360 degrees divided by 6, a rotation degree of 60 degrees, and a cross screw of 90 degrees. The first preset condition is that the screw is rotated at a low speed according to the degree of the screw rotation opening, and the low speed is a first preset speed. The first preset speed is set according to actual conditions, and preferably the setting conditions are as follows: when the screw assembly 400 rotates at the first preset speed, almost no abrasion is caused to the screw head grooving, the first preset speed is not too low, and the automatic screw locking action efficiency is low.
It will be readily appreciated that due to the nature of the screw assembly described above, when the screw assembly is rotated through a rotary port, if the screw is correctly positioned within the screw bore, the screw assembly will align with and jam the screw head groove.
Step S400: the detection unit detects whether the screw assembly is aligned with the screw head grooving or not when the screw assembly rotates;
step S500: and the control unit controls the screw locking tool assembly to drive the screw assembly to rotate according to a second preset condition when the screw assembly is aligned with the screw head grooving so as to lock the screw.
It will be readily appreciated that rotation of the screw assembly 400 detects whether the screw assembly 400 is aligned with the head groove, and that upon alignment of the screw assembly 400, the screw assembly 400 jams the head groove, at which time a screw locking operation can be initiated.
It should be noted that the second preset condition is rapid rotation, and the second preset condition is the screw locking speed in a normal state; the rotation speed in the second preset condition may be set according to actual conditions in consideration of the type of the screw and the loss of the screw thread, the screw hole thread.
The implementation method realizes that the screw head grooving is accurately found in the deep screw outer hole, and the screw is quickly locked; the screw head grooving machine has the advantages that damage caused by misalignment of the screw rod assembly is effectively prevented, manpower and material resources are saved, the efficiency of mechanical installation is improved, a visual recognition device does not need to be installed, and the automatic screw locking cost is reduced.
A second embodiment of the control method of the screw locking device according to the present invention is provided based on the first embodiment of the control method of the screw locking device according to the present invention, and referring to fig. 5, fig. 5 is a schematic flow chart of the second embodiment of the control method of the screw locking device according to the present invention.
The step S300 specifically includes:
step S301: the detection unit detects the type of the screw head grooving and sends a type signal to the control unit;
it will be readily appreciated that if the type of the screw assembly is known to the user, the type can be set directly by the user, writing the type into the memory unit of the control unit. This step can be omitted by direct control by the control unit.
It is easy to understand that, when the detection unit is a photoelectric switch, the photoelectric switch can identify the type of the screw assembly when the screw assembly is installed and inform the control unit of the type of the screw head grooving.
Step S302: the control unit generates a first preset condition according to the type signal and controls the screw locking tool assembly to drive the screw assembly to rotate according to the first preset condition.
It is easy to understand that, according to the above embodiment, the first preset condition is set according to the type of the screw head grooving and the first preset rotation speed, after the type signal is obtained, the first preset condition may be produced, and the screw locking tool assembly is driven to drive the screw assembly to rotate according to the first preset condition.
After step S400, the method further comprises:
step S401: when the screw rod assembly is not aligned with the screw head grooving, the control unit controls the screw locking tool assembly to be lifted and lowered again;
it will be readily appreciated that if the screw is not properly positioned within the screw bore, the screw head groove is not initially aligned parallel to the upper edge of the screw bore, making alignment of the screw assembly difficult. In this case, it is necessary to lift and lower again, and perform the alignment operation again.
Step S402: the detection unit detects whether the screw rod assembly enters the screw outer hole or not when the screw locking tool assembly descends again;
it is easy to understand that if the head of the screw assembly is separated from the interior of the screw outer hole during the lifting and descending processes, the head may be deviated from the screw outer hole during the descending process due to mechanical vibration, and the like, and the detection unit is required to detect and prevent the head from falling again. This step may also be omitted if the head of the screw assembly is not removed from the interior of the screw outer bore.
Step S403: and when the screw rod assembly enters the screw outer hole, the control unit controls the screw locking tool assembly to drive the screw rod assembly to rotate again according to a first preset condition.
It is easy to understand that the operation of aligning the screw head groove is performed again when the screw head is lowered again, which is a cyclic operation and will not be described again here.
After step S403, the method further includes:
step S501: and when the number of times that the screw locking tool assembly is lifted up and then descends reaches a preset number of times, the control unit controls the screw locking tool assembly to stop working and gives an alarm to a user.
It should be noted that, under the condition that the screw is incorrectly placed in the screw hole, the screw and the screw component can be lifted up and then fall down together through the adsorption action of the screw component, so as to find the correct position for placing in the screw hole, and the screw can also be assisted by the falling of the screw component so as to be placed correctly; however, in some cases, the above solutions cannot make the screw placed correctly, and the number of times of lifting and dropping reaches a preset number of times, and a user needs to manually place the screw in the screw hole correctly.
It should be noted that the preset times can be set according to actual conditions, and preferably can be set to be the unit times, so as to speed up the progress of executing the screw locking operation and give an alarm to the user as early as possible, so as to find the problem that the screw is placed askew.
After step S500, the method further comprises:
step S502: and detecting the state of the screw, and controlling the screw locking tool assembly to stop working when the state of the screw is locking.
It is easy to understand that, in the case where the screw has been locked, the screw locking tool assembly drives the screw assembly to rotate, and the resistance is sensed to reach a certain threshold value; the control unit with lock screw tool subassembly is connected, detectable lock screw tool subassembly's running state when detecting the resistance and having reached preset threshold value, then can know the screw locking, control lock screw tool subassembly stop work.
It is easy to understand that, after the screw is locked, the control unit can control the screw locking tool assembly to lift up, and control the screw locking tool assembly to move to the next screw, and repeatedly execute all the above actions, so as to realize mechanical automatic screw locking.
In a specific implementation, the screw locking device is provided with a screw assembly, and the screw assembly can not only perform screw locking operation but also perform screw loosening operation if the screw assembly is controlled to rotate reversely under the condition that the screw assembly is matched with the screw head grooving.
And according to a first preset condition and a second preset condition, reversely rotating the conditions to obtain a first loosened screw preset condition and a second loosened screw preset condition, and performing a loosened screw operation according to the first loosened screw preset condition and the second loosened screw preset condition, wherein the specific control method is the same as that of screw locking.
It is easy to understand that if there is a need to disassemble a component, i.e. there is a need to loosen a screw, the screw locking device of the present invention is also applicable to loosen a screw in a case where the screw outer hole of the component is deep. The control unit 100 may detect whether the screw is locked or not according to resistance received by the screw assembly, and may detect whether the screw is loosened or not according to resistance received by the screw assembly, and control the screw locking tool assembly to stop working when the screw is completely loosened.
It is easy to understand that, in the above embodiments, the screw assembly is a magnetic member, and if the screw is made of iron or contains iron, the screw assembly can attract the screw, take the screw out of the screw outer hole, and facilitate the worker to detach the component. After the screw loosening operation is performed, the control unit can control the screw locking tool assembly to lift up, control the screw locking tool assembly to move to the next screw, and repeatedly perform all the actions so as to achieve mechanical automatic screw loosening.
The embodiment of the invention prevents the problem that the screw locking operation cannot be carried out due to the fact that the screw is not accurately placed in the screw locking action, effectively discovers hidden dangers and gives an alarm to a user, and the device can automatically stop after the screw is locked, so that the groove abrasion of the head of the screw and the damage to the screw assembly and the screw locking tool assembly caused by the repeated locking of the screw are prevented; meanwhile, the method can also be used for loosening the screw, so that the automation of loosening/locking the screw is realized, and the damage of the screw head grooving caused by the fact that the screw assembly is not aligned with the screw head grooving is prevented.
