Technical Field

[0001] This utility model relates to the field of screw fastening technology, and in particular to an automatic screw fastening machine for terminal blocks. Background Technology

[0002] Currently, terminal blocks are generally fixed to sheet metal parts in two ways: one is by using guide rails for clamping, and the other is by using screws for fastening. Compared with guide rail clamping, screw fastening is easier to automate. Therefore, most terminal blocks are fixed to sheet metal parts by screw fastening to facilitate automated processing.

[0003] Terminal blocks are typically secured with screws using an automatic screw fastening machine. The sheet metal parts are placed in the designated positions, and the terminal blocks are placed on the sheet metal parts. Then, the automatic screw fastening machine fastens the screws to fix the terminal blocks to the sheet metal parts.

[0004] On some terminal blocks, to avoid interference between screws and other components, or to achieve better wiring results, screws at an angle are used to install the terminal blocks. Therefore, when encountering screw installation positions with special angles or terminal blocks with uneven surfaces, the positioning and tightening operations of the equipment may be inaccurate, or even malfunction. Utility Model Content

Detailed Implementation

[0023] The technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0024] Reference Figure 1 , Figure 2 and Figure 4 An embodiment of this utility model provides an automatic terminal block screw fastening machine, including a base 7. A bracket 1, a feeding device 6, and a workbench 9 are arranged on the upper side of the base 7. A slide plate 8 is slidably connected to the upper side of the workbench 9. Support plates 2 are fixedly connected to both sides of the upper side of the slide plate 8. A rotating rod 24 is rotatably connected to the side wall between the two support plates 2. A storage plate 14 is fixedly connected to the side wall of the rotating rod 24. A cylinder 13 is arranged on both sides of the storage plate 14. A clamping plate 22 is fixedly arranged at the output end of the cylinder 13. One end of the rotating rod 24 passes through the support plate 2. A gear 22 is fixedly connected to the end of the rotating rod 24 that passes through the support plate 2. A gear 11 is meshed with the tooth end of the gear 12. A motor 23 is arranged on one side of the gear 11. The motor 23 is arranged on the support plate 2. A moving mechanism 3 is slidably connected to the bracket 1. A tightening mechanism 4 is slidably connected to one side of the moving mechanism 3.

[0025] In this embodiment, Figure 1The directions are front, back, left, and right. The feeding device 6 is used to supply screws and can use a vibrating feeding tray; the tightening mechanism 4 is used to attract the screws on the feeding device 6 and fix them to the terminal block with a certain torque, and can use a torque-driven tightening shaft or a torque-driven electric screwdriver; all of the above are existing technologies.

[0026] Specifically, in use, the terminal block is placed on the storage plate 14. Driven by the output of the cylinder 13, the clamping plate 22 moves to abut against the terminal block and fix it. The sliding connection between the workbench 9 and the slide plate 8 causes the slide plate 8 to move backward, moving the terminal block to the corresponding position. The support plate 2 provides support for the motor 23. Driven by the output of the motor 23, the gear 11 rotates. The meshing connection between the gear 11 and the gear 22 causes the gear 22 to rotate. The fixed connection between the gear 22 and the rotating rod 24, and the rotational connection between the rotating rod 24 and the support plate 2, causes the rotating rod 24 to rotate. The fixed connection between the rotating rod 24 and the storage plate 14 causes the storage plate 14 to rotate, making the storage plate 14 rotate at a certain angle to the horizontal plane, so that the screw holes on the terminal block are perpendicular to the ground.

[0027] By sliding the moving mechanism 3 and the bracket 1 left and right, the moving mechanism 3 moves to above the feeding device 6. By sliding the tightening mechanism 4 and the moving mechanism 3 up and down, the tightening mechanism 4 slides down to attract the screw on the feeding device 6. Then, the tightening mechanism 4 slides to the left and moves to directly above the screw hole on the terminal block. The tightening mechanism 4 slides down to insert the screw into the screw hole on the terminal block. By rotating the tightening mechanism 4, the screw is fixed on the terminal block. This solves the problem that the positioning and tightening operation of the equipment may be deviated or even fail to work properly when the screw is installed at a special angle or the terminal block has an uneven surface.

[0028] Reference Figure 1 and Figure 2 The support 1 includes two vertical plates and a horizontal plate connecting the two vertical plates. The vertical plates of the support 1 are all fixedly connected to the upper side of the base 7, and the outer wall of the horizontal plate of the support 1 is slidably connected to the moving mechanism 3.

[0029] Specifically, the base 7 supports the vertical plate of the bracket 1, which in turn supports the horizontal plate of the bracket 1. Through the sliding connection between the horizontal plate of the bracket 1 and the moving mechanism 3, the moving mechanism 3 can move left and right, thereby enabling the tightening mechanism 4 to move left and right.

[0030] Reference Figure 1 and Figure 2The moving mechanism 3 includes a housing 19, with a roller 15 rotatably connected to the upper part of the housing 19. The side wall of the roller 15 is attached to the upper side of the cross plate of the support 1. A motor 5 is provided on one side of the housing 19. A gear 17 is fixedly provided at the output end of the motor 5. A rack 16 is meshed with the tooth end of the gear 17. The rack 16 is located on the lower side of the cross plate of the support 1. One side of the housing 19 is slidably connected to the tightening mechanism 4.

[0031] Specifically, when the moving mechanism 3 needs to move left or right, the output of motor 5 drives gear 17 to rotate. Through the meshing connection between gear 17 and rack 16, and the fixed connection between rack 16 and the horizontal plate of support 1, the reaction force of gear 17's rotation drives motor 5 to move horizontally. Through the connection between motor 5 and housing 19, housing 19 is moved left or right. Through the rotational connection between housing 19 and roller 15, and the contact between roller 15 and the upper side of the horizontal plate of support 1, roller 15 rolls on the upper side of the horizontal plate of support 1, thus realizing the function of left and right sliding connection between moving mechanism 3 and support 1.

[0032] Reference Figure 1 and Figure 2 An electric track 18 is provided on one side of the housing 19, and the output end of the electric track 18 is fixedly mounted on the tightening mechanism 4.

[0033] Specifically, the electric track 18 can move linearly on the housing 19, which is the existing technology; when the tightening mechanism 4 needs to move up and down, the housing 19 provides support for the electric track 18, and the output end of the electric track 18 drives the housing 19 to move up and down, thereby realizing the function of sliding connection between the moving mechanism 3 and the tightening mechanism 4.

[0034] Reference Figure 3 Both sides of the workbench 9 are equipped with electric rails 20, and the output end of the electric rails 20 is fixedly installed on the inner side wall of the slide plate 8.

[0035] Specifically, the electric track 20 can move linearly on the worktable 9, which is the existing technology; when the slide plate 8 needs to move back and forth, the output end of the electric track 20 drives the slide plate 8 to move back and forth, thereby realizing the function of sliding connection between the slide plate 8 and the worktable 9.

[0036] Reference Figure 4 The storage plate 14 has a groove in the middle, the output end of the cylinder 13 passes through the side wall of the storage plate 14, and the clamping plate 22 is set inside the groove of the storage plate 14.

[0037] Specifically, the terminal block is placed in the groove of the storage plate 14, and driven by the output ends of the two cylinders 13, the two clamping plates 22 move toward the terminal block to fix it, thereby achieving the fixation of the terminal block.

[0038] Reference Figure 4 A pressure sensor 21 is installed on the clamping plate 22.

[0039] Specifically, when the clamp 22 moves to fit against the terminal block, the pressure sensor 21 monitors the pressure between the clamp 22 and the terminal block in real time, and keeps the pressure between the pressure sensor 21 and the clamp 22 within a suitable range. This not only fixes the terminal block, but also prevents damage to the terminal block due to excessive pressure.

[0040] Reference Figure 1 , Figure 2 and Figure 3 A controller 10 is provided on one side of the base 7. The controller 10 is electrically connected to the tightening mechanism 4, motor 1 5, feeding device 6, cylinder 13, electric track 1 18, electric track 2 20, pressure sensor 21 and motor 2 23.

[0041] Specifically, the controller 10 can use a PLC controller, which is existing technology. When using this automatic screw fastening machine, the controller 10 controls the feeding device 6 to start, preparing the screws. The terminal block is placed in the groove of the storage plate 14. The controller 10 controls the cylinder 13, which fixes the clamping plate 22. The pressure sensor 21 monitors the pressure between the clamping plate 22 and the terminal block in real time and transmits the signal to the controller 10, which then controls the cylinder 13 to maintain the pressure between the clamping plate 22 and the terminal block within the normal range. The controller 10 controls the electric track 20 to start, which moves the slide plate 8 to the corresponding position. The controller 10 controls the motor 23 to start, which rotates the screw hole of the terminal block to be perpendicular to the ground. The controller 10 controls the tightening mechanism 4, the motor 5, and the electric track 18 to start, which moves the moving mechanism 3 to above the feeding device 6. After the screw on the feeding device 6 is attracted, it is moved to the terminal block and screwed into the screw hole. Thus, the automatic screw fastening machine is made intelligent.

[0042] Working principle: The terminal block is placed on the storage plate 14. Controlled by the controller 10, the clamping plate 22 is moved by the output of the cylinder 13 to hold the terminal block in place. The pressure between the pressure sensor 21 and the clamping plate 22 is kept within a suitable range by the feedback of the pressure sensor 21, thereby fixing the terminal block.

[0043] Controlled by the controller 10, the output of the motor 5 drives the gear 17 to rotate. The meshing connection between the gear 17 and the rack 16 causes the reaction force of the gear 17 to move the motor 5 left and right, which in turn moves the housing 19 left and right. Through the roller 15, the moving mechanism 3 and the bracket 1 are slidably connected. Driven by the output of the electric track 18, the housing 19 is moved up and down, thus realizing the tightening mechanism 4 moving up, down, left and right.

[0044] Controlled by controller 10, the output of electric track 20 drives the slide plate 8 to move to the corresponding position to the rear. Driven by the output of motor 23, gear 11 rotates, gear 2 rotates, and then rotating rod 24 rotates, thereby rotating storage plate 14 and making storage plate 14 rotate at a certain angle to the horizontal, so that the screw holes on the terminal block are perpendicular to the ground. The screws on the feeding device 6 are attracted by the tightening mechanism 4 and tightened to the screw holes on the terminal block. This solves the problem that the positioning and tightening operation of the equipment may be deviated or even fail to work properly when the screws are installed at special angles or the terminal blocks are uneven.

[0045] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
