Description

Technical Field

[0001] The invention relates to the technical field of welding equipment, in particular to a spot welding device with a positioning structure for processing a mainboard of a door access control machine. Background Art

[0002] Spot welding refers to the welding method that uses cylindrical electrodes to form welding spots between the contact surfaces of two overlapping workpieces. During spot welding, pressure is first applied to make the workpieces in close contact, and then the current is turned on. The contact of the workpieces melts under the action of resistance heat, and the welding spots are formed after cooling. Spot welding is mainly used for welding of thin plate components and stampings, and is particularly suitable for welding of automobile bodies and carriages, aircraft fuselages and circuit boards. The access control machine is the core control device of the access control system. It has reliable data storage, no data loss during power failure, and integrates management and automatic control to realize the automatic management of access control. The data can also be used for attendance, realizing the dual functions of access control and attendance. At the same time, it can be seamlessly connected with the one-card system. It is widely used in access control, attendance management, security alarm, parking management, elevator control, building automation, etc. in smart buildings or smart communities. It can also be linked with other systems for various control functions. The access control machine has a motherboard, which can provide a series of junctions for processors, graphics cards, sound cards, hard disks, memory, external devices and other devices to join. They are usually directly inserted into the relevant slots or connected with lines. The most important component on the motherboard is the chipset. When the access control machine mainboard is produced and processed, spot welding is required for the access control machine mainboard.

[0003] At present, during the operation of the existing spot welding machine, the overall use of the welding equipment is not flexible enough, which makes the welding work not smooth. At the same time, vibration will inevitably occur with the operation of the equipment, making the welding equipment unstable, inconvenient for batch welding, and affecting the overall welding quality. Summary of the invention

[0010] Preferably, the rectangular guide rail is installed vertically, the cylinder is installed directly above the welding main machine, and the spot welding head is installed directly below the welding main machine. When the telescopic end of the cylinder is extended and the welding main machine is driven to move downward, the zigzag guide rod is driven to move downward together, and is installed directly above the circular hole in combination with the zigzag guide rod, so that the bottom end of the zigzag guide rod moving downward is inserted into the circular hole, thereby limiting the position of the welding main machine, reducing the influence of external force and vibration, and preventing shaking.

[0011] Preferably, the circular roller and the servo motor are installed at the same height, and the positioning components are evenly distributed in the middle of the outer side of the conveyor belt.

[0012] When the conveyor belt is running, the edge of the spiral protrusion fits with the top of the inner wall of the conveyor belt, so that the spiral protrusion is driven by the conveyor belt, and the cylinder and the spiral protrusion rotate together under the rolling of the cylinder. The spiral protrusions on both sides are symmetrical in opposite directions, so that the running conveyor belt is subjected to the balancing force of the spiral protrusions, which makes it difficult for the conveyor belt to deviate and the transportation of the access control machine mainboard is accurate.

[0013] Preferably, there are two groups of spiral raised lines, and the two groups of spiral raised lines are symmetrically installed along the central axis in the middle of the conveyor belt.

[0014] Preferably, the positioning assembly includes a first padding strip, the bottom of the first padding strip is fixedly installed at the middle of the outer side of the conveyor belt, a second padding strip is fixedly installed at the outer side of the conveyor belt and close to the first padding strip, a square rod is fixedly installed at the top of the first padding strip and at a position corresponding to the top of the second padding strip, the square rod is installed at the side of the top of the first padding strip and the second padding strip, a J-shaped positioning frame is fixedly installed at the middle of the outer side of the square rod, a circular notch is opened at the bending part of the inner side of the J-shaped positioning frame, the access control machine mainboard to be processed is placed on the top of the first padding strip and the second padding strip, and the access control machine mainboard is embedded in the inside of the J-shaped positioning frame, so that the access control machine mainboard is positioned and is not prone to arbitrary displacement, so that the position of the access control machine mainboard is accurate;

[0015] At the same time, the corner of the access control machine main board is inside the circular notch, so that the access control machine main board is placed stably as a whole and it is not easy for materials to get stuck.

[0016] Preferably, the position of the first gasket strip corresponds to the position of the second gasket strip, and the J-shaped positioning frame is installed directly above the first gasket strip and the second gasket strip. The different lengths of the two sides of the J-shaped positioning frame make the J-shaped positioning frame appear notched, which facilitates the unloading of the welded access control machine mainboard.

[0018] Preferably, the planar support plate and the pressure rod are both installed at an angle, and the pressure rod is installed directly below the circular hole. When the welding host drives the zigzag guide rod to move upward, the bottom end of the zigzag guide rod is separated from the pressure rod, and the downward pressing force on the pressure rod disappears. Under the elastic pulling force of the elastic sheet, the pressure rod drives the planar support plate to rotate clockwise for reset.

[0019] Preferably, a material guide assembly is installed on the outer side of the connecting frame, and the material guide assembly is installed just below the round roller. The material guide assembly includes a connecting sleeve, and the connecting sleeve is slidably installed on the side of the outer side of the connecting frame.

The guide plate is installed at an angle to guide the access control machine main board, so that the access control machine main board will not fall directly.

[0045] The first embodiment, as Figure 1-Figure 3 As shown, the present invention provides a technical solution: a spot welding device for processing a mainboard of an access control machine with a positioning structure, comprising:

[0046] The frame 1 has a supporting frame body, a supporting frame 2 is installed on the side of the top of the frame 1, and a circular hole 3 is opened on the top of the frame 1 and close to the supporting frame 2;

[0047] A mainboard processing mechanism 4, which is used to perform spot welding processing on the mainboard of the access control machine, and the mainboard processing mechanism 4 is installed on the top of the support frame 2;

[0048] Among them, the mainboard processing mechanism 4 includes a rectangular guide rail 41, which is fixedly installed on the side of the top of the support frame 2, and a cylinder 42 is installed in the middle of the top of the rectangular guide rail 41. A welding host 43 is slidably installed in the middle of the inner cavity of the rectangular guide rail 41. The top of the welding host 43 is fixedly installed with the telescopic end of the cylinder 42, and a spot welding head 44 is installed at the bottom of the welding host 43. A zigzag guide rod 45 is fixedly installed on the outside of the welding host 43 and close to the spot welding head 44. The staff turns on the cylinder 42 to work, and uses the extension and contraction of the telescopic end of the cylinder 42, and combines the rectangular guide rail 41 to guide the welding host 43, so that the welding host 43 is driven by the telescopic end of the cylinder 42 to move downward and upward, so that the spot welding head 44 moves with the welding host 43, and the position of the spot welding head 44 can be adjusted, so that the spot welding head 44 is at a suitable distance from the mainboard of the access control machine to be processed, so as to facilitate spot welding of the mainboard of the access control machine;

[0049] The rectangular guide rail 41 is installed vertically, the cylinder 42 is installed just above the welding main machine 43, and the spot welding head 44 is installed just below the welding main machine 43. When the telescopic end of the cylinder 42 is extended and the welding main machine 43 is driven to move downward, the zigzag guide rod 45 is driven to move downward together, and combined with the zigzag guide rod 45 installed just above the circular hole 3, the bottom end of the zigzag guide rod 45 moving downward is inserted into the circular hole 3, so that the welding main machine 43 can be limited.

[0050] The second embodiment, as Figure 1-Figure 7 As shown, based on the second embodiment:

[0051] A transport mechanism 5, which is used to transport the access control machine mainboard to be processed, and is installed in the middle of the frame 1;

[0052] Among them, the transportation mechanism 5 includes a connecting frame 51, which is fixedly installed in the middle of the frame 1 and close to the top position. Round rollers 52 are rotatably installed at both ends of the top of the connecting frame 51. A servo motor 53 is fixedly installed on the outside of the connecting frame 51 and close to the round roller 52. The output end of the servo motor 53 is fixedly installed between the round roller 52 through a coupling. A conveyor belt 54 is installed in the middle of the outside of the round roller 52. A positioning component 55 is installed in the middle of the outside of the conveyor belt 54. A cylinder 56 is rollingly installed between the corresponding two sides of the connecting frame 51 and close to the conveyor belt 54 through a bent rod. Spiral raised lines 57 are fixedly installed at the corresponding positions on the outer surface of the cylinder 56. The staff turns on the servo motor 53 to work. By rotating the output end of the servo motor 53, the round roller 52 can be driven to rotate, so that the conveyor belt 54 can be operated to move the access control machine motherboard to be processed toward the discharge direction, thereby automatically loading.

[0053] The round roller 52 and the servo motor 53 are installed at the same height, and the positioning components 55 are evenly distributed in the middle of the outer side of the conveyor belt 54.

[0054] There are two groups of spiral raised lines 57, and the two groups of spiral raised lines 57 are symmetrically installed along the central axis in the middle of the conveyor belt 54. When the conveyor belt 54 is running, the edges of the spiral raised lines 57 are in contact with the top of the inner wall of the conveyor belt 54, so that the spiral raised lines 57 are driven by the conveyor belt 54, and under the rolling of the cylinder 56, the cylinder 56 and the spiral raised lines 57 can rotate together. The spiral raised lines 57 on both sides are symmetrical in opposite directions, so that the running conveyor belt 54 is subjected to the balancing force of the spiral raised lines 57, which makes it difficult for the conveyor belt 54 to deviate.

[0055] The positioning assembly 55 includes a first padding strip 551, the bottom of which is fixedly installed at the middle of the outer side of the conveyor belt 54, a second padding strip 552 is fixedly installed at the outer side of the conveyor belt 54 and close to the first padding strip 551, a square rod 553 is fixedly installed at the top of the first padding strip 551 and the corresponding position of the top of the second padding strip 552, the square rod 553 is installed at the side of the top of the first padding strip 551 and the second padding strip 552, a J-shaped positioning frame 554 is fixedly installed at the middle of the outer side of the square rod 553, and a circular notch 555 is provided at the bending part of the inner side of the J-shaped positioning frame 554. The staff places the access control machine mainboard to be processed on the top of the first padding strip 551 and the second padding strip 552, and embeds the access control machine mainboard into the inside of the J-shaped positioning frame 554, so that the access control machine mainboard is positioned and is not prone to arbitrary displacement, so that the access control machine mainboard is accurately positioned;

[0056] At the same time, the corner of the access control machine main board is inside the circular notch 555, so that the access control machine main board is placed stably as a whole.

[0057] The position of the first gasket strip 551 corresponds to the position of the second gasket strip 552, and the J-shaped positioning frame 554 is installed directly above the first gasket strip 551 and the second gasket strip 552. The different lengths of the two sides of the J-shaped positioning frame 554 make the J-shaped positioning frame 554 appear notched, which facilitates the unloading of the access control machine mainboard after welding.

[0058] The third embodiment, as Figure 1-Figure 11 As shown, based on the second embodiment and the second embodiment:

[0059] A lifting assembly 6 is installed at the top of the inner cavity of the frame 1. The lifting assembly 6 includes a base 61. The top of the base 61 is fixedly installed with the top of the inner cavity of the frame 1. The base 61 is installed at a position close to the circular hole 3. A plane support plate 62 is rotatably installed at the middle of the outer side of the base 61. The plane support plate 62 is installed at a position close to the cylinder 56. A compression rod 63 is fixedly installed at the edge of the top of the plane support plate 62. An elastic sheet 64 is fixedly installed between the outer side of the compression rod 63 and the top of the inner cavity of the frame 1. When the curved After the bottom end of the folding guide rod 45 is inserted into the circular hole 3, as the folding guide rod 45 continues to move downward, the bottom end of the folding guide rod 45 can apply a downward pressing force to the pressure rod 63, thereby driving the flat support plate 62 to rotate counterclockwise through the pressure rod 63 to adjust the angle, and the elastic sheet 64 is stretched. The flat support plate 62 is in a horizontal state after the angle is adjusted, so that the top of the flat support plate 62 is in contact with the top of the inner wall of the conveyor belt 54, and the conveyor belt 54 can be lifted.

[0060] The plane support plate 62 and the pressure rod 63 are both installed at an angle, and the pressure rod 63 is installed directly below the circular hole 3. When the welding host 43 drives the zigzag guide rod 45 to move upward, the bottom end of the zigzag guide rod 45 is separated from the pressure rod 63, and the downward pressing force on the pressure rod 63 disappears. Under the elastic pulling force of the elastic sheet 64, the pressure rod 63 drives the plane support plate 62 to rotate clockwise for reset.

[0061] A material guide assembly 7 is installed on the outside of the connecting frame 51, and the material guide assembly 7 is installed just below the round roller 52. The material guide assembly 7 includes a connecting sleeve 71, which is slidably installed on the side of the outside of the connecting frame 51, and the connecting sleeve 71 is installed at a position close to the round roller 52. A material guide plate 72 is fixedly installed at the end of the connecting sleeve 71 away from the connecting frame 51, and a toggle tooth 73 is fixedly installed in the middle of the top of the material guide plate 72. The toggle tooth 73 is installed just below the conveyor belt 54, and an elastic reset member 74 is fixedly installed between the bottom of the connecting sleeve 71 and the bottom of the connecting frame 51. A material blocking plate 75 is fixedly installed at the side of the top, and a gasket 76 is fixedly installed at the middle of the top of the guide plate 72. With the operation of the conveyor belt 54, the access control machine main board that has been welded is conveyed in the direction of the guide plate 72. When the access control machine main board is conveyed to the end of the conveyor belt 54, the short side of the J-shaped positioning frame 554 is downward, so that the access control machine main board can fall onto the guide plate 72 and make the access control machine main board contact with the gasket 76, so as to protect the access control machine main board. The guide plate 72 is installed obliquely to guide the access control machine main board, so that the access control machine main board will not fall directly.

[0062] The guide plate 72 is installed at an angle, and there are two baffle plates 75, and the two baffle plates 75 are installed symmetrically along the toggle tooth 73. The material of the gasket 76 is silicone material. As the conveyor belt 54 drives the J-shaped positioning frame 554 to continue to move, the J-shaped positioning frame 554 that runs to the bottom of the conveyor belt 54 contacts the toggle tooth 73. As the J-shaped positioning frame 554 continues to move, the toggle tooth 73 is pressed by the J-shaped positioning frame 554, and under the sliding connection of the connecting sleeve 71, the connecting sleeve 71 and the guide plate 72 move downward together, and the elastic reset member 74 is compressed. When the J-shaped positioning frame 554 is separated from the toggle tooth 73, the pressing force on the toggle tooth 73 disappears, and under the elastic force of the elastic reset member 74, the connecting sleeve 71 drives the guide plate 72 to move upward for reset, and the guide plate 72 can be screened up and down to promote the discharge of the material on the main board of the access control machine.

[0063] When in use, the staff first places the access control machine mainboard to be processed on the top of the first padding strip 551 and the second padding strip 552, and embeds the access control machine mainboard into the J-shaped positioning frame 554, so that the access control machine mainboard is positioned and is not prone to random displacement;

[0064] At this time, the staff starts the servo motor 53 to work, and the output end of the servo motor 53 is rotated to drive the roller 52 to rotate, so that the conveyor belt 54 can be operated, and the access control machine mainboard to be processed is moved toward the discharge direction, so as to automatically load the material, and when the conveyor belt 54 is in operation, the edge of the spiral convex line 57 is in contact with the top of the inner wall of the conveyor belt 54, so that the spiral convex line 57 is driven by the conveyor belt 54, and under the rolling of the cylinder 56, the cylinder 56 and the spiral convex line 57 can be rotated together, and the spiral convex lines 57 on both sides are symmetrical and move in opposite directions, so that the running conveyor belt 54 is subjected to the balancing force of the spiral convex line 57, so that the conveyor belt 54 is not easy to deviate, and when the access control machine mainboard to be processed is transported to the bottom of the spot welding head 44, the servo motor 53 can be stopped;

[0065] At the same time, the staff starts the cylinder 42 to work, uses the telescopic end of the cylinder 42 to extend, and combines the rectangular guide rail 41 to guide the welding main machine 43, so that the welding main machine 43 is driven downward by the telescopic end of the cylinder 42, so that the spot welding head 44 moves with the welding main machine 43, and the position of the spot welding head 44 can be adjusted. When the telescopic end of the cylinder 42 extends and drives the welding main machine 43 to move downward, the zigzag guide rod 45 is driven to move downward together, and combined with the zigzag guide rod 45 installed just above the circular hole 3, the bottom end of the zigzag guide rod 45 moving downward is inserted into the circular hole 3, so that the welding main machine 43 can be limited.

[0066] As the zigzag guide rod 45 continues to move downward, the bottom end of the zigzag guide rod 45 applies a downward pressing force to the pressure rod 63, thereby driving the flat support plate 62 to rotate counterclockwise through the pressure rod 63 to adjust the angle, and the elastic sheet 64 is stretched. The flat support plate 62 after the angle adjustment is in a horizontal state, so that the top of the flat support plate 62 fits with the top of the inner wall of the conveyor belt 54, and the conveyor belt 54 can be lifted;

[0067] With the spot welding head 44 being at a suitable distance from the access control machine mainboard to be processed, it is convenient to spot weld the access control machine mainboard;

[0068] After the spot welding of the main board of the access control machine is completed, the telescopic end of the cylinder 42 can be retracted again to lift the welding main board 43, so that the bottom end of the zigzag guide rod 45 is separated from the pressure rod 63, and the downward pressure on the pressure rod 63 disappears. Under the elastic tension of the elastic sheet 64, the pressure rod 63 drives the flat support plate 62 to rotate clockwise to reset;

[0069] At this time, the servo motor 53 is turned on again to work. With the operation of the conveyor belt 54, the access control machine main board that has been welded is conveyed in the direction of the material guide plate 72. When the access control machine main board is conveyed to the end of the conveyor belt 54, the short side of the J-shaped positioning frame 554 is downward, so that the access control machine main board can fall onto the material guide plate 72, and the access control machine main board can contact the gasket 76 to protect the access control machine main board. The material guide plate 72 is installed obliquely to guide the access control machine main board.

[0070] As the conveyor belt 54 drives the J-shaped positioning frame 554 to continue to move, the J-shaped positioning frame 554 that runs to the bottom of the conveyor belt 54 contacts the toggle tooth 73. As the J-shaped positioning frame 554 continues to move, the toggle tooth 73 is pressed by the J-shaped positioning frame 554, and under the sliding connection of the connecting sleeve 71, the connecting sleeve 71 and the guide plate 72 move downward together, and the elastic reset member 74 is compressed. When the J-shaped positioning frame 554 is separated from the toggle tooth 73, the pressing force on the toggle tooth 73 disappears, and under the elastic force of the elastic reset member 74, the connecting sleeve 71 drives the guide plate 72 to move upward for reset, and the guide plate 72 can be screened up and down to promote the discharge of materials from the main board of the access control machine.
