Description

Technical Field

[0001] The invention relates to the technical field of switch socket assembly machines, and in particular to a fixing device for switch socket assembly processing. Background Art

[0002] A switch socket is a socket that can be plugged into one or more circuit wirings. Various wirings can be inserted through it, so that it is easy to connect with other circuits. The connection and disconnection between the circuit and the copper parts can ultimately achieve the connection and disconnection of this part of the circuit. It generally includes a fixing frame, a phosphor bronze component, a protective door, a PC back panel and a flame retardant door panel.

[0003] A complete set of assembly machines is used in the assembly process. Usually, a jig for placing a fixed frame is set on the conveyor belt to transport the basic components. The fixed frame moves along the conveyor above the jig and passes through the mechanical parts of the phosphor bronze components, protective doors, PC back panels, flame-retardant door panels, etc. in turn. They assemble and fix these components in turn under the action of the corresponding mechanism.

[0004] At present, the jig for placing the fixing frame is usually provided with a matching groove on the top of the jig, and the fixing frame is directly placed in the groove. It is difficult to ensure that the size of the groove is completely consistent with the external size of the fixing frame during the processing process. This causes the fixing frame to shake during the movement when it is placed inside the groove, thereby reducing the assembly accuracy. In addition, the groove and the bottom of the fixing frame are both horizontal structures, and when the fixing frame is fixed on the top of the groove, the two may be adsorbed together;

[0005] When grabbing the assembled switch socket, the flame retardant panel is grabbed, and the flame retardant panel is glued to the PC back panel, and the glue has not solidified yet. The two are firmly adsorbed, causing the flame retardant panel to fall off when grabbing. For this reason, we designed a fixing device for assembly and processing of switches and sockets. Summary of the invention

[0006] The present invention provides a fixing device for assembly and processing of a switch socket, which solves the problem that when a fixing frame is placed inside a groove, it may shake during movement, thereby reducing the assembly accuracy.

[0007] In order to achieve the above object, the present invention adopts the following technical solutions:

[0008] A fixing device for assembly and processing of switches and sockets, comprising a conveyor belt, a plurality of equally spaced bases are arranged above the conveyor belt, four symmetrically distributed L-shaped side frames are fixed above each of the bases, a placement plate is fixed by screws between the inner sides of the four L-shaped side frames, the placement plate is suspended above the base, an L-shaped clamping plate is slidably installed at the four corners above the placement plate, a lifting opening is formed through the center of the placement plate, an ejection plate is slidably arranged in the lifting opening, a lifting sleeve is fixed at the center below the ejection plate, and two groups of lifting slide bars are arranged in a circular array below the inner circle of the lifting sleeve;

[0009] A driving mechanism is provided at the center of the upper part of each base, and a fixing mechanism is respectively installed at the four corners above the base, the fixing mechanism comprises a rotating shaft rotatably installed between the base and the placement plate through a bearing, a threaded upper half of the outer ring surface of the rotating shaft is provided to form a spiral portion, a lifting nut is threadedly connected to the spiral portion, a connecting biasing plate is rotatably installed on the outward side of the lifting nut through an axle pin, and a moving guide rod is rotatably connected to the end of the connecting biasing plate away from the lifting nut through an axle pin, and a clamping slide hole is respectively opened at four diagonals on the upper and lower sides of the placement plate, and the upper end of the moving guide rod passes through the clamping slide hole and is connected to the lower surface of the L-shaped clamping plate;

[0010] The driving mechanism includes a rotating shaft rotatably installed at the center above the base through a bearing, a driving toothed belt wheel is installed at the bottom end of the outer ring of the rotating shaft, and a driven toothed belt wheel is installed at the lower half of the outer ring of the rotating shaft. The driving toothed belt wheel and multiple driven toothed belt wheels are connected and transmitted by a toothed belt, and two groups of lifting screw grooves are arranged in a circular array on the upper half of the outer ring surface of the rotating shaft. The lifting screw groove includes a lifting groove arranged in a spiral structure on the outer surface of the rotating shaft, and the lifting slide rod is slidably placed in the lifting groove.

[0011] Furthermore, the lifting nut can move up and down under the action of the spiral part. During the downward movement of the lifting nut, the end of the connecting bias plate will be pulled downward. At this time, the entire L-shaped clamping plate will move inward along the clamping slide hole, and the four L-shaped clamping plates will approach each other. The workpiece placed inside will be clamped and fixed. When the lifting nut moves upward, the four L-shaped clamping plates will synchronously move outward and away from each other, thereby releasing the clamping of the workpiece.

[0012] Furthermore, a guide slide is provided on the inward side of each lifting nut, and a guide column is fixed at each of the four corners of the upper surface of the base. The four guide slides are respectively slidably sleeved with the four guide columns, which can limit the rotation of the lifting nut, thereby allowing the lifting nut to move up and down when the spiral part rotates, thereby facilitating the inward or outward movement of the L-shaped clamping plate.

[0013] Furthermore, the clockwise transmission of the rotating shaft can make the four driven toothed pulleys rotate synchronously clockwise, and then make the corresponding rotating shaft and spiral part rotate clockwise. At this time, the four lifting nuts will move downward synchronously, and the four L-shaped clamping plates will approach each other, and the workpiece placed inside them will be clamped and fixed. When the rotating shaft rotates counterclockwise, the four rotating shafts and the spiral part will rotate synchronously counterclockwise, and the four L-shaped clamping plates will move outward synchronously away from each other, thereby releasing the clamping of the workpiece.

[0014] Furthermore, a driving gear is fixedly sleeved on the outer ring of the rotating shaft above the active toothed pulley, and a driving rod 1 and a driving rod 2 are symmetrically arranged on the left and right sides of the driving gear, and a plurality of linearly distributed meshing teeth are arranged on the surface of the one side of the driving rod 1 and the driving rod 2 close to each other, and the driving rod 1 and the driving rod 2 on the left and right sides are respectively meshed and connected with the left and right sides of the driving gear through a plurality of meshing teeth. Pushing the driving rod 1 and moving it backward can make the driving gear rotate clockwise, and then the rotating shaft can rotate clockwise. At this time, the multiple rotating shafts will rotate clockwise accordingly, and then the four L-shaped clamping plates can approach each other, and the workpiece placed inside thereof will be clamped and fixed. Pushing the driving rod 2 to move it inward can make the rotating shaft rotate counterclockwise through the driving gear, and the four rotating shafts will rotate counterclockwise together, and then the four L-shaped clamping plates can synchronously move outward and away from each other, thereby releasing the clamping of the workpiece.

[0015] Furthermore, the driving rod 1 and the driving rod 2 are in an L-shaped structure as a whole, which increases the width of the front end of the driving rod 1 and the driving rod 2, so as to facilitate contact with the push rods of the fixing cylinder and the unlocking cylinder;

[0016] The lower end surface of the placement plate is symmetrically provided with two groups of movable sliders, and the upper surfaces of the driving rod 1 and the driving rod 2 are both installed with movable rails by screws. The movable sliders are slidably connected with the movable rails. The setting of the movable sliders and the movable rails can guide the forward and backward movement of the driving rod 1 and the driving rod 2, making their operation more stable, and can provide a support for the driving rod 1 and the driving rod 2.

[0017] Furthermore, a horizontal groove is provided on the outer surface of the rotating shaft, the bottom end of the lifting groove is connected to one end of the horizontal groove, the number of spiral turns of the lifting groove is 0.5, and the arc length of the horizontal groove is 1 / 4 of the circumference of the outer ring of the rotating shaft.

[0018] Furthermore, in the initial state, that is, when the upper surface of the ejector plate is coplanar with the upper surface of the placement plate, the lifting slide bar is at the connection between the horizontal groove and the lifting groove, the maximum stroke of the ejector plate is less than the thickness of the ejector plate, and the thickness of the ejector plate is consistent with the thickness of the placement plate. When the rotating shaft rotates clockwise, the lifting slide bar can slide along the horizontal groove. At this time, the height of the entire lifting sleeve will not change, and the ejector plate remains in its original state. When it rotates counterclockwise, the lifting slide bar first slides along the horizontal groove and then slides along the lifting groove. Since the lifting groove rises in a spiral shape, the entire lifting sleeve will rise therewith, thereby making the ejector plate protrude, so that the workpiece can be separated from the contact with the placement plate.

[0019] Furthermore, a fixing cylinder and an unlocking cylinder are respectively installed on the starting end and the end side of the conveyor belt, the push rod of the fixing cylinder is aligned with the driving rod 1 at the rightmost end, and the push rod of the unlocking cylinder is aligned with the driving rod 2 at the leftmost end. At the starting end, the workpiece is placed above the placement plate, and then the fixing cylinder pushes the driving rod 1 to move backward. At this time, the rotating shaft rotates clockwise, the ejection plate remains unchanged, and the four L-shaped clamping plates move inward synchronously to clamp and fix the workpiece. When it moves to the leftmost end, the switch socket has been assembled, and the unlocking cylinder pushes the driving rod 2 to move backward, and the four L-shaped clamping plates move outward synchronously to contact and clamp the workpiece, and then continue to push the driving rod 2. After the lifting slide bar is placed in the lifting slot, the ejection plate will move upward a certain distance, so that the entire assembled workpiece moves up as a whole, and breaks away from the contact with the placement plate, to prevent the bottom of the workpiece from being adsorbed by the placement plate, making it difficult to remove.

[0020] Beneficial effects of the present invention:

[0021] 1. The placement plate is suspended between the four L-shaped side frames above the base, and L-shaped clamping plates are slidably arranged at the four diagonals above the placement plate. A fixing mechanism is respectively arranged at the four corners between the bottom of the placement plate and the base. The four L-shaped clamping plates are respectively connected to the four fixing mechanisms, and the fixing mechanisms are connected to the driving mechanism in the middle. When the bottom shell of the switch socket is initially placed on the placement plate, the four L-shaped clamping plates can be synchronously moved inward and clamped and fixed, thereby facilitating subsequent assembly, and shaking is not likely to occur during the assembly process, thereby improving the accuracy.

[0022] 2. An ejector plate is movably arranged up and down in the lifting opening in the center of the placement plate. The ejector plate is connected to the driving mechanism through a lifting sleeve and a lifting slide rod. When the driving mechanism clamps the switch socket with the L-shaped clamping plate, its position will not change. After the assembly is completed and the switch socket is released, the ejector plate can move upward under the action of the driving mechanism, thereby causing the switch socket to move upward as a whole, preventing it from being adsorbed by the placement plate and causing inconvenience in removal.

[0035] The driving mechanism 8 includes a rotating shaft 86 rotatably installed at the center above the base 1 through a bearing, a driving toothed pulley 88 is installed at the bottom end of the outer ring of the rotating shaft 86, a driven toothed pulley 64 is installed on the lower half of the outer ring of the rotating shaft 62, the driving toothed pulley 88 and multiple driven toothed pulleys 64 are connected and transmitted by a toothed belt 7, two groups of lifting screw grooves are arranged in a circular array on the upper half of the outer ring surface of the rotating shaft 86, the lifting screw groove includes a lifting groove 861 arranged on the outer surface of the rotating shaft 86 in a spiral structure, and the lifting slide rod 52 is slidably placed in the lifting groove 861.

[0036] The lifting nut 61 can move up and down under the action of the spiral part 63. During the downward movement of the lifting nut 61, one end of the connecting bias plate 66 will be pulled downward. At this time, the entire L-shaped clamping plate 3 will move inward along the clamping slide hole 41, and the four L-shaped clamping plates 3 will approach each other. The workpiece placed inside will be clamped and fixed. When the lifting nut 61 moves upward, the four L-shaped clamping plates 3 will move outward synchronously away from each other to release the clamping of the workpiece.

[0037] A guide slide 68 is provided on the inward side of each lifting nut 61, and a guide column 67 is fixed at each of the four corners of the upper surface of the base 1. The four guide slides 68 are respectively slidably sleeved with the four guide columns 67, which can limit the rotation of the lifting nut 61, so that the lifting nut 61 moves up and down when the spiral portion 63 rotates, which is convenient for the L-shaped clamping plate 3 to move inward or outward.

[0038] The clockwise transmission of the rotating shaft 86 can make the four driven toothed pulleys 64 rotate clockwise synchronously, and then make the corresponding rotating shaft 62 and spiral part 63 rotate clockwise. At this time, the four lifting nuts 61 will move downward synchronously, and the four L-shaped clamping plates 3 will approach each other, and the workpiece placed inside them will be clamped and fixed. When the rotating shaft 86 rotates counterclockwise, the four rotating shafts 62 and spiral part 63 will rotate counterclockwise synchronously, and the four L-shaped clamping plates 3 will move outward synchronously away from each other, thereby releasing the clamping of the workpiece.

[0039] The outer ring of the rotating shaft 86 is fixedly sleeved with a driving gear 87 above the driving toothed pulley 88. The left and right sides of the driving gear 87 are symmetrically provided with a driving rod 1 81 and a driving rod 2 82. The surfaces of the driving rod 1 81 and the driving rod 2 82 close to each other are both provided with a plurality of linearly distributed meshing teeth 83. The driving rod 1 81 and the driving rod 2 82 on the left and right sides are respectively meshed and connected with the left and right sides of the driving gear 87 through a plurality of meshing teeth 83. Pushing the driving rod 1 81 and moving it backward can make the driving gear 87 rotate. 7 rotates clockwise, thereby enabling the rotating shaft 86 to rotate clockwise, and the multiple rotating shafts 62 will rotate clockwise accordingly, thereby enabling the four L-shaped clamping plates 3 to approach each other, and the workpiece placed inside thereof will be clamped and fixed, and the driving rod 82 is pushed to move it inward, so that the rotating shaft 86 can be rotated counterclockwise through the driving gear 87, and the four rotating shafts 62 will rotate counterclockwise accordingly, thereby enabling the four L-shaped clamping plates 3 to move outward synchronously away from each other, thereby releasing the clamping of the workpiece.

[0040] The driving rod 1 81 and the driving rod 2 82 are L-shaped as a whole, which increases the width of the front end of the driving rod 1 81 and the driving rod 2 82 to facilitate contact with the push rods of the fixing cylinder 91 and the unlocking cylinder 92;

[0041] Two groups of movable sliders 85 are symmetrically arranged on the left and right sides of the lower end surface of the placement plate 4. The upper surfaces of the driving rod 1 81 and the driving rod 2 82 are installed with movable rails 84 by screws. The movable sliders 85 are slidingly connected to the movable rails 84. The arrangement of the movable sliders 85 and the movable rails 84 can guide the forward and backward movement of the driving rod 1 81 and the driving rod 2 82, making their operation more stable, and can provide a support for the driving rod 1 81 and the driving rod 2 82.

[0042] The outer surface of the rotating shaft 86 is also provided with a horizontal groove 862 . The bottom end of the lifting groove 861 is connected to one end of the horizontal groove 862 . The number of spiral turns of the lifting groove 861 is 0.5. The arc length of the horizontal groove 862 is 1 / 4 of the circumference of the outer circle of the rotating shaft 86 .

[0043] In the initial state, that is, when the upper surface of the ejector plate 5 is coplanar with the upper surface of the placement plate 4, the lifting slide bar 52 is at the connection between the horizontal groove 862 and the lifting groove 861, and the maximum stroke of the ejector plate 5 is less than the thickness of the ejector plate 5. The thickness of the ejector plate 5 is consistent with the thickness of the placement plate 4. When the rotating shaft 86 rotates clockwise, the lifting slide bar 52 can slide along the horizontal groove 862. At this time, the height of the entire lifting sleeve 51 will not change, and the ejector plate 5 remains in its original state. When it rotates counterclockwise, the lifting slide bar 52 first slides along the horizontal groove 862, and then slides along the lifting groove 861. Since the lifting groove 861 rises in a spiral shape, the entire lifting sleeve 51 will rise therewith, thereby making the ejector plate 5 protrude, so that the workpiece can be separated from the contact with the placement plate 4.

[0044] The starting end and the end side of the conveyor belt 9 are respectively installed with a fixing cylinder 91 and an unlocking cylinder 92. The push rod of the fixing cylinder 91 is aligned with the driving rod 1 81 at the far right end, and the push rod of the unlocking cylinder 92 is aligned with the driving rod 2 82 at the far left end. At the starting end, the workpiece is placed above the placement plate 4, and then the fixing cylinder 91 pushes the driving rod 1 81 to move backward. At this time, the rotating shaft 8 rotates clockwise, and the ejection plate 5 remains unchanged. The four L-shaped clamping plates 3 move inward synchronously to clamp and fix the workpiece. When it moves to the leftmost end, the switch socket has been assembled. The unlocking cylinder 92 pushes the driving rod 2 82 to move backward, and the four L-shaped clamping plates 3 move outward synchronously to contact and clamp the workpiece, and then continue to push the driving rod 2 82. After the lifting slide bar 52 is placed in the lifting slot 861, the ejection plate 5 will move upward a certain distance, thereby causing the entire assembled workpiece to move upward as a whole, and break away from the contact with the placement plate 4, to prevent the bottom of the workpiece from being adsorbed by the placement plate 4, making it difficult to remove.

[0045] Working principle: The device is placed at the right end above the conveyor belt 9, and a fixed cylinder 91 and an unlocking cylinder 92 are respectively arranged at the left and right ends of the conveyor belt 9, wherein the push rod of the fixed cylinder 91 is aligned with the driving rod 1 81 in the driving mechanism 8 at the rightmost end, and the push rod of the unlocking cylinder 92 is aligned with the driving rod 2 82 in the driving mechanism 8 at the leftmost end;

[0046] In actual use, the bottom shell of the switch socket will be placed on the placement plate 4 and placed between the four L-shaped clamping plates 3 under the action of the manipulator, and then the push rod of the fixed cylinder 91 will extend and push the driving rod 81 to move backward. Since the driving rod 81 is meshed with the driving gear 87 through the meshing teeth 83, the rotating shaft 86 will rotate clockwise, and the driving toothed belt wheel 88 on the rotating shaft 86 will rotate together. Because the driving toothed belt wheel 88 is connected to the four driven toothed belt wheels 64 through the toothed belt 7, and the four driven toothed belt wheels 64 are respectively installed on the four rotating shafts 62, the four rotating shafts 62 will rotate clockwise together. At this time, the four lifting nuts 61 will move downward synchronously, and the four L-shaped clamping plates 3 will approach each other, and the bottom shell of the switch socket placed inside them will be clamped and fixed;

[0047] Then the bottom shell of the switch socket will move to the left along with the conveyor belt 9, and in the process of moving to the left, the phosphor bronze component, the protective door and the PC back plate will be placed on the bottom shell of the switch socket one by one by the external manipulator and fixed by a screw machine, and then a layer of glue will be applied on the surface of the PC back plate, and the flame retardant panel will be pressed on the top of the bottom shell by the manipulator and contacted and connected with the PC back plate;

[0048] After that, the device continues to move leftward to the leftmost end of the conveyor belt 9, and at this time, the push rod of the unlocking cylinder 92 is aligned with the second driving rod 82 in the device, and the push rod of the unlocking cylinder 92 is pushed out and causes the second driving rod 82 to move backward. At this time, the rotating shaft 86 will cause the four rotating shafts 62 to rotate counterclockwise synchronously, and the four L-shaped clamping plates 3 will move outward synchronously to release the clamping fixation of the switch socket;

[0049] In the process of the four L-shaped clamping plates 3 moving inward to clamp and fix the bottom shell of the switch socket, the lifting slide bar 52 can slide along the horizontal groove 862. At this time, the height of the entire lifting sleeve 51 will not change, and the ejection plate 5 remains in its original state. In the process of the four L-shaped clamping plates 3 moving outward to release the bottom shell of the switch socket, the four L-shaped clamping plates 3 will first move away from the bottom shell, and then the lifting slide bar 52 will move into the spiral lifting groove 861. Under its action, the ejection plate 5 will move upward and make the bottom shell break away from the contact connection with the placement plate 4, and at this time, the four L-shaped clamping plates 3 will continue to move away from the bottom shell;

[0050] By suspending the placement plate 4 between the four L-shaped side frames 2 above the base 1, and slidingly setting L-shaped clamping plates 3 at the four diagonal positions above the placement plate 4, respectively setting a fixing mechanism 6 at the four corners between the bottom of the placement plate 4 and the base 1, the four L-shaped clamping plates 3 are respectively connected to the four fixing mechanisms 6, and the fixing mechanism 6 is connected to the driving mechanism 8 in the middle, when the bottom shell of the switch socket is initially placed on the placement plate 4, the four L-shaped clamping plates 3 can be synchronously moved inward and clamped and fixed, thereby facilitating subsequent assembly, and shaking is not likely to occur during the assembly process, thereby improving the accuracy;

[0051] An ejector plate 5 is movably arranged up and down in the lifting opening at the center of the placement plate 4. The ejector plate 5 is connected to the driving mechanism 8 through the lifting sleeve 51 and the lifting slide rod 52. When the driving mechanism 8 clamps the switch socket with the L-shaped clamping plate 3, its position will not change. After the assembly is completed and the switch socket is released, the ejector plate 5 can move upward under the action of the driving mechanism 8, thereby making the switch socket move upward as a whole, preventing it from being adsorbed by the placement plate 4 and causing inconvenience in removal.
