[0001] The invention relates to the technical field of power supply assembly, and in particular to a power supply housing locking device. Background Art

[0002] Industrial control power supply is a power supply specially designed for industrial automation control equipment and systems. It is responsible for providing stable power support for various industrial control equipment (such as PLC, industrial PC, CNC system, sensor, etc.). The industrial control power supply includes a circuit board and a shell. The circuit board is provided with multiple screw holes, and the shell is provided with multiple through holes. The multiple through holes correspond to the multiple screw holes. The circuit board is installed inside the shell to ensure that the circuit board can operate normally for a long time. The power shell locking device is a device that installs the shell on the circuit board by screws.

[0003] In the prior art, when it is necessary to install the housing on the circuit board, the operator will first send the circuit board and the housing into the first power housing locking device, so that the first power housing locking device tightens the screws on the top surface of the housing. Then the operator will send the circuit board and the housing into the second power housing locking device, so that the second power housing locking device tightens the screws on the left side of the housing. Finally, the operator will send the circuit board and the housing into the third power housing locking device, so that the third power housing locking device tightens the screws on the right side of the housing to complete the installation of the housing. This method requires the operator to carry the circuit board and the housing back and forth between multiple devices, which takes a certain amount of time and is not conducive to improving the installation efficiency of the housing. Summary of the invention

[0004] The present invention aims to solve at least one of the technical problems existing in the prior art. To this end, the present invention provides a power supply housing locking device, which is conducive to improving the installation efficiency of the housing.

[0039] Additional aspects and advantages of the present invention will be given in part in the following description and in part will be obvious from the following description, or will be learned through practice of the present invention.

[0040] refer to Figures 1 to 4 The power supply housing locking device of the present invention includes a frame 100, a rotation driving device 200, a pressing device 300, a positioning fixture 400, a screw feeding device 500 and a screw tightening device 600.

[0041] The rotary drive device 200 is arranged on the frame 100, the positioning fixture 400 is connected to the output end of the rotary drive device 200, the clamping device 300 is arranged on the positioning fixture 400, the positioning fixture 400 is used to position the circuit board and the housing, the clamping device 300 is used to clamp the circuit board and the housing on the positioning fixture 400, and the rotary drive device 200 is used to drive the positioning fixture 400 to rotate so that the top surface, left side surface and right side surface of the housing can face upward in sequence. The screw feeding device 500 is arranged on the frame 100, and the screw feeding device 500 is used to supply screws. The screw tightening device 600 is arranged on the frame 100, and the screw tightening device 600 is used to tighten the screws at the discharge end of the screw feeding device 500 on the top surface, left side surface and right side surface of the housing in sequence.

[0042] The rotary drive device 200, the screw feeding device 500 and the screw tightening device 600 are all connected to the frame 100. The screw feeding device 500 can accommodate multiple screws and can drive the screws to move to the discharge end of the screw feeding device 500 at a certain frequency. The screw feeding device 500 can be a common circular vibration feeder. The output end of the rotary drive device 200 is connected to the positioning jig 400. The positioning jig 400 can position the circuit board and the housing so that the multiple screw holes on the circuit board correspond to the multiple through holes on the housing. The clamping device 300 on the positioning jig 400 can clamp the circuit board and the housing on the positioning jig 400, thereby preventing the circuit board and the housing from falling off the positioning jig 400 when the rotary drive device 200 drives the positioning jig 400 to rotate.

[0043] It is understandable that when the housing needs to be installed on the circuit board, the operator can place the circuit board and the housing together on the positioning jig 400. After the circuit board and the housing are placed on the positioning jig 400, the pressing device 300 presses the circuit board and the housing on the positioning jig 400 to prevent the circuit board and the housing from falling off the positioning jig 400. After the circuit board and the housing are pressed, the rotary drive device 200 drives the positioning jig 400 to rotate so that the top surface of the housing on the positioning jig 400 faces upward. At this time, the screw tightening device 600 tightens the screws at the discharge end of the screw feeding device 500 on the top surface of the housing so that the top surface of the housing is fixed on the circuit board. Then the rotary drive device 200 continues to drive the positioning jig 400 to rotate so that the left side of the housing on the positioning jig 400 faces upward. At this time, the screw tightening device 600 tightens the screws at the discharge end of the screw feeding device 500 on the left side of the housing so that the left side of the housing is fixed on the circuit board. Finally, the rotary drive device 200 continues to drive the positioning jig 400 to rotate, so that the right side of the shell on the positioning jig 400 faces upward. At this time, the screw tightening device 600 tightens the screws at the discharge end of the screw feeding device 500 on the right side of the shell, so that the right side of the shell is fixed on the circuit board to complete the installation of the shell. After the shell is installed, the clamping device 300 loosens the circuit board and the shell, and the operator can remove the circuit board and the shell from the positioning jig 400. The power supply shell locking device drives the positioning jig 400 to rotate so that the top surface, left side surface and right side surface of the shell can face upward in turn, thereby completing the installation of the shell, eliminating the need for the operator to carry the circuit board and the shell back and forth, which is beneficial to improving the installation efficiency of the shell.

[0044] It should be explained that, in the initial state, when the operator places the circuit board and the housing on the positioning fixture 400, the top surface of the housing is facing upward. After the screw tightening device 600 tightens the screws on the top surface of the housing, the rotation drive device 200 drives the positioning fixture 400 to rotate so that the left side and the right side of the housing can face upward in sequence.

[0045] In an embodiment of the present invention, the power supply housing locking device further includes a cover 110 and a work platform (not shown in the figure). The cover 110 is mounted on the frame 100, and the cover 110 can cover the rotary drive device 200, the positioning fixture 400, the slide 710, the linear drive device 700, the clamping device 300, the screw feeding device 500 and the screw tightening device 600. An operation hole 111 is provided on the right side wall of the cover 110, and the operation hole 111 is used for the operator's hand to extend into, so that the operator can place the circuit board and the housing on the positioning fixture 400 or remove it from the positioning fixture 400. The work platform is connected to the cover 110, and the work platform is arranged at a position corresponding to the operation hole 111. The operator's hand can be placed on the work platform, and the circuit board and the housing can also be placed on the work platform. It should be explained that before placing the circuit board and the housing on the positioning fixture 400, the operator needs to first put the circuit board into the housing so that the multiple screw holes on the circuit board correspond to the multiple through holes on the housing.

[0046] refer to Figures 4 to 6 The power supply housing locking device also includes a linear drive device 700 and a slide 710. The slide 710 can be connected to the frame 100 in a sliding manner in the left and right directions. The rotary drive device 200 is arranged on the slide 710. The linear drive device 700 is used to drive the slide 710 to slide in the left and right directions. It can be understood that the rotary drive device 200 is connected to the slide 710, and the positioning fixture 400 is connected to the output end of the rotary drive device 200. When the operator needs to place the circuit board and the housing on the positioning fixture 400, the linear drive device 700 drives the slide 710 to move to the right, so that the positioning fixture 400 is close to the operating hole 111, so that the operator can pass the circuit board and the housing through the operating hole 111 and place them on the positioning fixture 400. After the circuit board and the housing are placed, the linear drive device 700 drives the slide 710 to move to the left, so that the positioning fixture 400 and the circuit board and the housing on the positioning fixture 400 are close to the screw tightening device 600, so that the screw tightening device 600 can smoothly screw the screws. After the housing is installed, the linear drive device 700 drives the slide 710 to move to the right, so that the positioning fixture 400 is close to the operating hole 111, and the operator can remove the circuit board and the housing from the positioning fixture 400.

[0047] As an embodiment of the present invention, a safety grating 120 is further provided on the cover 110, and the safety grating 120 is arranged at a position corresponding to the operating hole 111. The safety grating 120 is a common component for protecting operators, and will not be further described here.

[0048] refer to Figure 4 and Figure 5 The linear drive device 700 includes a linear drive cylinder 730, the cylinder body of the linear drive cylinder 730 is arranged on the frame 100, the piston rod of the linear drive cylinder 730 is connected to the slide 710, and the linear drive cylinder 730 is used to drive the slide 710 to move in the left and right directions. The linear drive device 700 also includes two buffers 720, which are respectively arranged on the front and rear sides of the linear drive cylinder 730, and the two buffers 720 can abut against the slide 710 to reduce the moving speed of the slide 710.

[0049] It is understandable that when the piston rod of the linear drive cylinder 730 is extended, the slide 710 moves to the right, and when the piston rod of the linear drive cylinder 730 is retracted, the slide 710 moves to the left. During the process of the piston rod of the linear drive cylinder 730 being retracted, the slide 710 can abut against the two buffers 720 to reduce the speed of the slide 710 moving to the left, and prevent the linear drive cylinder 730 from being damaged by the inertial impact of the slide 710. In the embodiment of the present invention, the buffer 720 can be a hydraulic buffer rod.

[0050] refer to Figure 6 and Figure 7 The rotary drive device 200 includes a rotary drive member 210 and a transmission rod 220. The rotary drive member 210 is arranged on the slide 710. One end of the transmission rod 220 is rotatably connected to the slide 710. The other end of the transmission rod 220 is connected to the output end of the rotary drive member 210. The transmission rod 220 is connected to the positioning fixture 400. The rotary drive member 210 can drive the transmission rod 220 to rotate, so that the transmission rod 220 drives the positioning fixture 400 to rotate.

[0051] It is understandable that the positioning fixture 400 is connected to the transmission rod 220, and the rotating drive member 210 drives the transmission rod 220 to rotate, so that the positioning fixture 400 can be rotated, and then the top surface, left side surface and right side surface of the shell can be sequentially facing upward. As an embodiment of the present invention, the rotating drive member 210 can be a motor, and three limiting holes are provided on the transmission rod 220. The motor is used to drive the transmission rod 220 to rotate so that the top surface, left side surface and right side surface of the shell can be sequentially facing upward, and the three limiting holes can be sequentially facing downward. The power supply shell locking device also includes a screw nut drive assembly and a limiting support block. The screw nut drive assembly is arranged on the slide 710, and the limiting support block is connected to the output end of the screw nut drive assembly. The screw nut drive assembly can drive the support block to be inserted into the limiting hole so that the support block can limit the rotation of the transmission rod 220.

[0052] It is understandable that here, taking the left side of the shell as an example, when the screw needs to be tightened on the left side of the shell, the motor drives the transmission rod 220 to rotate, so that the left side of the shell on the positioning fixture 400 faces upward, and one of the limit holes faces downward. Then the screw nut driving assembly drives the support block to rise, so that the support block is inserted into the limit hole. The support block can abut against the inner wall of the limit hole, that is, the support block can limit the transmission rod 220, effectively avoiding the rotation of the transmission rod 220 and the positioning fixture 400, so as to ensure that the subsequent screw tightening device 600 can smoothly screw the nail. On the other hand, in the process of screw tightening device 600 screwing the nail, the support block can support the transmission rod 220 and the positioning fixture 400, so that the screw tightening device 600 can screw the nail smoothly. Similarly, no matter which side of the shell faces up, there is a limit hole facing downward. The screw nut driving assembly can drive the support block to move in the up and down directions. The screw nut driving assembly is a common driving assembly and will not be further described here.

[0053] refer to Figure 7 , a positioning groove 410 is provided on the positioning jig 400, and the positioning groove 410 is used to position the circuit board and the housing. A hand hole 420 is provided on the positioning jig 400, and the hand hole 420 is connected to the positioning groove 410. It can be understood that when the housing needs to be installed, the operator can place the circuit board and the housing in the positioning groove 410, and the inner wall of the positioning groove 410 can position the circuit board and the housing. When the circuit board and the housing need to be removed from the positioning groove 410, the operator can insert a finger into the hand hole 420 so that the operator can remove the circuit board and the housing.

[0054] refer to Figure 6 and Figure 7The positioning jig 400 is provided with a stopper 430, which can abut against the housing in the positioning slot 410, so that the multiple screw holes on the circuit board correspond to the multiple through holes on the housing. In the embodiment of the present invention, the stopper 430 is arranged on the left end of the positioning jig 400, and the stopper 430 can abut against the housing, so that the multiple through holes on the housing correspond to the multiple screw holes on the circuit board.

[0055] refer to Figure 6 and Figure 7 The pressing device 300 includes a lifting cylinder 310 and a pressing block 320. The cylinder body of the lifting cylinder 310 is connected to the positioning jig 400. The piston rod of the lifting cylinder 310 is connected to the pressing block 320. The lifting cylinder 310 can drive the pressing block 320 to approach the positioning jig 400 so that the pressing block 320 presses the housing and the circuit board onto the positioning jig 400. It can be understood that after the circuit board and the housing are placed on the positioning jig 400, the lifting cylinder 310 drives the pressing block 320 to approach the positioning jig 400 so that the pressing block 320 presses against the housing, thereby pressing and fixing the circuit board and the housing onto the positioning jig 400. After the housing is installed, the lifting cylinder 310 drives the pressing block 320 away from the positioning jig 400 so that the pressing block 320 releases the housing, and the operator can remove the circuit board and the housing from the positioning jig 400. As an embodiment of the present invention, a flexible pad is provided on the side of the pressing block 320 facing the positioning fixture 400, and the pressing block 320 presses the housing and the circuit board onto the positioning fixture 400 through the flexible pad. It can be understood that the pressing block 320 is pressed against the housing through the flexible pad, thereby preventing the pressing block 320 from scratching the housing.

[0056] In the embodiment of the present invention, reference Figure 8 The screw tightening device 600 includes a screw adsorbing member, an electric screwdriver bit 620 and a manipulator 610. The output end of the manipulator 610 is connected to the screw adsorbing member and the electric screwdriver bit 620. The manipulator 610 can drive the screw adsorbing member and the electric screwdriver bit 620 to move in the left-right direction, the front-back direction and the up-down direction. The screw adsorbing member can magnetically attract the screws at the discharge end of the screw feeding device 500. When the screws need to be tightened on the outer shell, the manipulator 610 drives the screw adsorbing member to move to the discharge end of the screw feeding device 500, so that the screw adsorbing member can magnetically attract the screws. Then the manipulator 610 drives the screw adsorbing member and the electric screwdriver bit 620 to move above the positioning fixture 400, so that the screws magnetically attracted by the screw adsorbing member are aligned with the through holes on the outer shell. Then the manipulator 610 drives the screw adsorbing member and the electric screwdriver bit 620 to descend, and the electric screwdriver bit 620 drives the screw magnetically attracted by the screw adsorbing member to rotate, so that the screw passes through the through hole on the housing and is threadedly connected to the inner wall of the screw hole on the circuit board to complete the tightening of the screw. The screw tightening device 600 is a common device and will not be further described here.
