[0002] The deadbolt is a part of the lock, which is installed in the hole of the door and is used to cooperate with the lock hole set on the door frame to lock the door on the door frame.

[0003] Since the installation of the lock tongue requires it to be placed in the hole on the side of the door car, and the panel on the lock tongue needs to be in the same plane with the side of the door after installation and cannot protrude outward, this type of installation is a complicated installation process, so the lock tongue is often installed on the door manually.

[0004] There are also visual systems that work with robots to install the lock tongue on the door, but such devices are expensive and not suitable for large-scale popularization. Summary of the invention

[0005] Existing lock tongues are basically installed manually, or if they are installed automatically, they are completed through complex visual coordination with a robot. The investment cost of the entire equipment is too high, and thus it is not suitable for actual production.

[0006] The invention aims at the deficiencies in the prior art and provides an assembly machine for installing a lock tongue and a use method thereof.

[0007] To solve the above technical problems, the present invention is solved through the following technical solutions: an assembly machine for installing a lock tongue, comprising a base plate, a guide sliding on the base plate is provided with a movable frame for driving the lock tongue to move, a clamping part for supporting the lock tongue is provided on the movable frame, the movable frame cooperates with the clamping part to send the lock tongue into the chisel hole of the door, a screwing device, the screwing device comprises a magnetic part for magnetically attracting screws, a screwing part, the screwing part is penetrated on the magnetic part, the front end of the screwing part can be retracted into the magnetic part, and a screw bit cooperating with the tail groove of the screw is provided at the front end, the screwing part rotates and extends forward to drive the screw adsorbed on the front end of the magnetic part to rotate, and a telescopic part is arranged on the mobile device, and can drive the screwing part to move forward and backward.

[0008] The beneficial effect is that the lock tongue is automatically installed on the door panel through the assembly function, eliminating the manual installation process, and at the same time, low-cost equipment is used to complete the work of automatically installing the lock tongue, reducing the investment cost of the equipment.

[0009] In the above scheme, preferably, the screwing member is elastically limited and slidably arranged on the magnetic member, and the front end of the magnetic member is provided with a positioning column adapted to the mounting hole on the lock tongue for positioning the lock tongue.

[0031] The following further describes the present invention in detail in conjunction with the drawings and the specific embodiments: Refer to Figures 1-6 , an assembly machine for installing a lock tongue, including a bottom plate 1, a moving frame 2, and a screwing device 3. The assembly machine is fixedly arranged on the supporting equipment through the bottom plate 1, such as one side of the door production line or one side of the robot. The door panel is transported to the side of the assembly machine by the robot or the production line.

[0032] A track 11 is provided on the bottom plate 1. The moving frame 2 is guidingly and slidably arranged on the track 11, and a power component is configured on the moving frame 2 so that the moving frame 2 can move on the track 11. The track 11 can be transformed into a linear module, and then the moving frame 2 can be driven to move on the track 11 by a servo motor. Or one end of an electric telescopic rod is connected to the moving frame 2, and the other end of the electric telescopic rod is arranged on the bottom plate 1, and thus the moving frame 2 can also be moved on the track 11.

[0033] A plurality of sliding grooves 22 are arranged side by side on the moving frame 2. A slider 23 is guidingly and slidably arranged in each sliding groove 22. The upper end surface of the slider 23 is flush with the upper end surface of the moving frame 2. An clamping member 24 is telescopically arranged on the slider 23. When the clamping member 24 extends upward, the upper end surface of the clamping member 24 is higher than the upper end surface of the slider 24. When it retracts downward, the upper end surface is flush with the upper end surface of the slider 24. A pressure switch is configured on the front end surface of the slider 24. The clamping member 24 is controlled to move up and down by an electric push rod or an electromagnet. In the initial state, the clamping member 24 is in the upward extending state. When the pressure switch is pressed, the clamping member 24 retracts downward into the slider 24.

[0034] The locking tongue 4 includes a mounting plate 41 and a main body member 42. The edges of the mounting plate 41 all extend beyond the edges of the main body member 42. When the locking tongue 4 is placed on a flat plate, the locking tongue 4 is in an inclined state. However, when the locking tongue 4 is inserted into the mortise in the door panel, it needs to be in a horizontal state to be pushed in. Therefore, the upper planes of the slider 24 and the moving frame 2 are used to support the side wall of the mounting plate 41 of the locking tongue 4, and the extending clamping member 24 is used to support the main body member 42, so that the locking tongue 4 is in a horizontal state when placed on the moving frame 2, and thus can be horizontally pushed into the mortise in the door panel.

[0035] A blanking device 21 is also provided on the moving frame 2. The blanking device 21 includes a guide pipe 211 and a guide groove 212. The guide pipe 211 is fixedly arranged on the moving frame 2. The guide groove 212 is arranged in the longitudinal direction. Only one screw can pass through the guide groove 212. Thus, the screws are arranged in a single row and guided in the guide groove 212. The guide groove 212 communicates with the guide pipe 211. Therefore, the screws slide downward and enter the guide pipe 211.

[0036] The screwing device 3 includes a magnetic attracting member 31, a screwing member 32, a telescopic member 33, and a power member 34. The power member 34 is a hollow motor and is fixedly arranged on the moving frame 2. A polygonal shaft 321 is arranged at the middle position of the screwing member 32, and a part of the polygonal shaft 321 is slidably arranged on the hollow shaft of the power member 34 in a guiding manner. Thus, when the power member 34 rotates, it drives the screwing member 32 to rotate. The telescopic member 33 is an electric telescopic member, which is fixedly arranged on the moving frame 2. A rotating plate is fixedly arranged at the front end position of the telescopic member 33. A ring groove is formed at the rear end of the screwing member 32, and the screwing member 32 is rotatably arranged on the rotating plate through the ring groove. Thus, the telescopic member 33 moves back and forth to drive the screwing member 32 to move back and forth. A bit matching the groove at the tail of the screw is arranged at the front end of the screwing member 32. Thus, the screwing member 32 can screw the screw into the door panel.

[0037] The magnetic attracting member 31 is slidably arranged in the guiding tube 211 in a guiding manner and is elastically and slidably arranged on the screwing member 32. In the initial state, the front end of the screwing member 32 retracts into the magnetic attracting member 31, and the magnetic attracting member 31 is located below the guiding groove 212. Thus, the guiding groove 212 is blocked, and the screw cannot fall downward into the guiding tube 211. A positioning post 311 is arranged at the front end of the magnetic attracting member 31, and the outer diameter of the positioning post 311 is the same as the size of the mounting hole on the mounting plate 41. Two mounting holes are arranged on the mounting plate 41. Therefore, two sets of the screwing device 3 are configured.

[0038] Its working principle or usage method is as follows:

[0039] The lock tongue 4 is placed on the moving frame 2 through mechanical hand or manual positioning. The mounting plate 41 is located between the clamping member 24 and the guiding tube 211. At this time, the clamping member 24 supports on the bottom surface of the main body member 42, and the upper end surfaces of the slider 23 and the moving frame 2 support the bottom surface of the mounting plate 41. The lock tongue 4 is in a horizontal state, and the axes of the two mounting holes on the mounting plate 41 are the same as the axis of the screwing member 32. At this time, the telescopic member 33 drives the screwing member 32 to move forward, and thus drives the magnetic attracting member 31 to move forward together, so that the positioning post 311 on the magnetic attracting member 31 is inserted into the mounting hole. At the same time, the magnetic attracting member 31 abuts against the front end face of the mounting plate 41. At this time, the screwing member 32 continues to move forward, and the magnetic attracting member 31 pushes the lock tongue to move forward together. When the rear end face of the mounting plate 41 abuts against the clamping member 24, the lock tongue 4 stops moving. And at this time, the magnetic attracting member 31 and the clamping member 24 cooperate to clamp the mounting plate 41 back and forth, so that the lock tongue 4 is positioned and locked on the moving frame 2. At this time, the positioning and locking of the lock tongue 4 are completed. In this state, the front end of the screwing member 32 is still inside the magnetic attracting member 31.

[0040] After the manipulator or transfer line positions and transfers the door panel to be adjacent to the assembling machine and presses it tightly, the chiseled hole of the door panel is aligned with the main body 42 of the lock tongue 4 on the assembling machine. At this time, the moving frame 2 starts to move on the track 11, and then pushes the lock tongue 4 into the chiseled hole. After a part of the main body 42 is inserted into the chiseled hole, the front end wall of the slider 24 presses against the side wall of the door. A pressure switch is arranged on the front end wall of the slider 24. Therefore, when the slider 24 presses against the door panel, the pressure switch is pressed, and the clamping part 24 retracts downward into the slider 24, and the limit on the rear end face of the mounting plate 41 disappears, and the locking of the lock tongue 4 is released. The positioning post 311 of the magnetic attracting part 31 is still located in the mounting hole of the mounting plate 41. When the moving frame 2 continues to move along the track 11, the magnetic attracting part 31 continues to push the lock tongue 4 to move, and then completely pushes the lock tongue 4 into the chiseled hole of the door panel. Under the top touch of the door panel, the slider 24 moves relatively along the sliding groove 22, and at the same time compresses the elastic part located in the sliding groove 22. After the moving frame 2 moves in place, the lock tongue 4 is completely pushed into the chiseled hole of the door panel.

[0041] After the moving frame 2 moves in place, the telescopic part 33 drives the screwing part 32 to start moving backward, and then drives the magnetic attracting part 31 to move backward. The front end face of the positioning post 311 of the magnetic attracting part 31 has magnetic attraction. Therefore, during the backward movement of the magnetic attracting part 31, it will not drive the lock tongue 4 to move backward together.

[0042] When the magnetic attracting part 31 touches against the mounting plate 41, the magnetic attracting part 31 still blocks the guiding groove 212. During the backward movement of the magnetic attracting part 31, the front end of the magnetic attracting part 31 leaves below the guiding groove 212. Then, a screw in the guiding groove 212 falls downward into the guiding tube 211. After the screw falls into the guiding tube 211, the telescopic part 33 drives the screwing part 32 to start moving forward. The front end of the magnetic attracting part 31 adsorbs the tail of the screw. After protruding from the guiding tube 211, the screw is still adsorbed on the front end of the magnetic attracting part 31. At this time, the screwing part 32 continues to move forward, and then inserts the screw into the mounting hole. The front end of the screw touches against the plate in front of the mounting hole. At this time, the magnetic attracting part 31 no longer moves forward, and the power part 34 starts to rotate, and then drives the screwing part 32 to rotate together. After the screwing part 32 starts to rotate and move forward and touches against the tail of the screw, it cooperates with the notch of the tail to drive the screw to start rotating, and then screws the screw into the door panel, and then fixes the lock tongue 4 on the door panel through the screw. After the screw is completely screwed into the door panel, the power part 34 stops rotating, and the telescopic part 33 drives the screwing part 32 to start retracting and returns to the initial state.

[0043] The moving frame 2 also starts to move backward and returns to the initial state. During the movement, the slider 24 returns to the initial position under the action of the elastic part. After returning to the initial position, the moving frame 2 continues to move backward, and then the pressure on the pressure switch at the front end of the slider 24 disappears, and then the clamping part 24 rises and returns to the initial state. Example 2

[0044] The following further improvements are made to this example based on Example 1: For details, see Figures 1-6 , a detection device is further provided on the moving frame 2. The detection device includes a lifting block 25. The lifting block 25 is controlled by electricity or hydraulics to move up and down on the moving frame 2. An arc surface 251 is provided at the upper end of the lifting block 25, and a slot hole 252 is provided at the middle position. A photoelectric switch is provided in the slot hole 252.

[0045] After the tongue lock 4 is installed on the door panel by screws, at this time, the screwing member 32 starts to retreat, and at the same time, the lifting block 25 rises. During the upward movement of the arc surface of the lifting block 25, it touches the arc surface of the lock core. Under normal circumstances, the lock core retracts into the lock tongue. When the slot hole 252 is aligned with the lock core, the lock core pops out and enters the slot hole 252, and the photoelectric switch is blocked, thereby determining that the lock core is normal.

[0046] When the lifting block 25 moves upward and the lock core cannot retract backward into the lock tongue, the lifting block 25 is stuck and cannot rise. At this time, the photoelectric switch cannot be blocked, or after the lock core retracts into the lock tongue, it cannot pop out. At this time, the photoelectric switch cannot be blocked either. Therefore, when the photoelectric switch cannot be blocked, it is determined that the tongue lock 4 has a fault, and thus the tongue lock is automatically detected after the installation of the tongue lock is completed.

[0047] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit them; although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that: they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
