Description

Technical Field

[0001] The invention relates to the technical field of photorelay manufacturing, and in particular to a clamping device for photorelay manufacturing equipment. Background Art

[0002] In the prior art, a photorelay is a relay that uses light signals for control. It realizes the on-off control of the circuit through the principle of photoelectric conversion. In the manufacturing process of the photorelay, a related clamping device is usually used to clamp the photorelay accordingly to ensure that the photorelay can be more stable during the manufacturing process. In order to avoid damage to the outer wall of the photorelay during the clamping process, the existing clamping device usually has a rubber pad structure on the clamping side. However, since the rubber pad is often made of elastic material and has a certain elastic effect, the reciprocating squeezing and recovery between the rubber pad and the outer wall of the photorelay after long-term use will cause the elastic force of the rubber pad to decrease and fail. However, the existing clamping device lacks effective monitoring and response measures for the decrease and failure of the elastic force of the rubber pad. With the long-term use of the rubber pad, its rebound performance will gradually weaken, resulting in unstable clamping force, which in turn affects the manufacturing accuracy and product quality of the photorelay. In addition, once the elastic force of the rubber pad fails, if it is not discovered and replaced in time, it will also cause damage to the photorelay during the manufacturing process, increasing production costs and scrap rates.

[0024] The effects achieved by this embodiment are as follows: compared with the prior art, by setting up the rebound failure replacement mechanism 9, utilizing the extension of the first piston rod 813, and cooperating with the meshing rotation between the gear 901 and the toothed plate 913, the rotating shaft 801 can be driven to rotate, so that the old and new rubber pads 7 on both sides of the mounting seat 802 are automatically switched, thereby realizing the process of automatically triggering the switching when the failure is detected, reducing manual intervention, and improving production efficiency and accuracy. By utilizing the rebound failure of the rubber pad 7, the mechanism can respond quickly and switch, which can effectively avoid production quality problems caused by the degradation of the performance of the rubber pad 7. This timeliness and efficiency ensure the continuity and stability of the production line, and there is no need to stop for replacement, thereby reducing downtime, improving equipment utilization and production efficiency, and ensuring that rubber pads 7 with good performance can always be used for clamping, which helps to improve the manufacturing quality of the photorelay, reduce the scrap rate, and thus reduce the manufacturing cost.

[0025] The complete usage steps and working principle of the above embodiment are as follows: It should be noted that in the initial state, Figure 1 , Figure 2 as well as Figure 3As shown, two side plates are symmetrically fixed at the front end of the top of the workbench 1, and a threaded rod 2 is rotatably arranged between the side plates. A driving motor is fixedly arranged on the front side plate, and the output end of the driving motor is fixedly connected to the threaded rod 2. A T-shaped linkage plate 3 is threadedly arranged on the outer surface of the threaded rod 2. When the driving motor starts running, the threaded rod 2 can be driven to rotate between the two side plates, and the T-shaped linkage plate 3 is synchronously driven to move on the outer surface of the threaded rod 2. The T-shaped linkage plate 3 is slidably arranged on the upper surface of the workbench 1, so the T-shaped linkage plate 3 will also slide on the top of the workbench 1 at the same time to cooperate with the rotation drive of the threaded rod 2. Since the upper surface of the workbench 1 is also symmetrically slidably arranged with moving rods 5, connecting plates 4 are rotatably arranged between the two ends of the T-shaped linkage plate 3 and the moving rod 5. During the movement of the T-shaped linkage plate 3, the two moving rods can be driven by the connecting effect of the connecting plate 4. The rod 5 moves toward or away from each other on the upper surface of the workbench 1, and a fixed plate 6 is fixedly set on the top of the moving rod 5, and a rotating shaft 801 in the air pressure rebound monitoring mechanism 8 is rotatably set at the bottom of the opposite end of the fixed plate 6, and a mounting seat 802 is fixedly set on the outer surface of the rotating shaft 801, and rubber pads 7 are set on both sides of the mounting seat 802 through the mounting plate 806. In the process of clamping the photorelay placed on the upper surface of the placement plate 101, the two moving rods 5 move toward each other, and the two opposite rubber pads 7 can be driven to move toward each other synchronously, and the outer walls of the two sides of the photorelay are clamped accordingly. At the end of the manufacturing of the photorelay, the driving motor can be driven to run in the reverse direction, so that the two opposite rubber pads 7 move in the reverse direction synchronously and separate from the outer walls of the two sides of the photorelay, thereby ending the clamping action of the photorelay and restoring the position of the structure.

[0026] The following is the working process of the air pressure rebound monitoring mechanism 8 monitoring the rebound function of the rubber pad 7: In the process of clamping the outer walls of both sides of the photorelay, Figure 1 and Figure 2As shown, first, the staff can turn on the driving motor to drive the threaded rod 2 to rotate in the forward direction. At this time, the T-shaped linkage plate 3 with threads set on the outer surface of the threaded rod 2 will move synchronously with the outer surface of the threaded rod 2 toward the front end direction of the workbench 1 as the threaded rod 2 rotates. Since the T-shaped linkage plate 3 is rotatably connected to the moving rod 5 through the connecting plate 4, when the T-shaped linkage plate 3 moves, the two moving rods 5 can be synchronously driven to move toward each other, and a fixed plate 6 is fixed on the top of the moving rod 5, and a rotating shaft 801 is rotatably set at the bottom of the fixed plate 6. The outer surface of the rotating shaft 801 The mounting seats 802 are fixedly connected to the surfaces. When the moving rods 5 move toward each other, the fixing plate 6 synchronously follows and drives the two mounting seats 802 to move toward each other synchronously. Because the rubber pads 7 are symmetrically arranged on both sides of the mounting seats 802, the two rubber pads 7 facing each other will move toward each other synchronously under the drive, and the photorelay placed on the upper surface of the placement plate 101 will be clamped accordingly. At this time, the rubber pads 7 will fit tightly on the outer walls of both sides of the photorelay. Through the friction between the structures, the rubber pads 7 can be squeezed synchronously while clamping the photorelay. Figure 3 , Figure 4 as well as Figure 8 As shown, a cavity 811 is provided in the rubber pad 7, and a first gas pipe 812 is fixedly provided through the mounting seat 802, and the first gas pipe 812 and the cavity 811 are communicated with each other, so that when the rubber pad 7 is squeezed, the gas inside the cavity 811 is transported to the inside of the first gas pipe 812, and a first piston rod 813 is slidably provided through the bottom of the first gas pipe 812, and under the push of gas, the first piston rod 813 can be driven to slide vertically downward inside the first gas pipe 812, and in the process of ending the clamping and moving the rubber pad 7 to the initial position, since the clamping effect of the rubber pad 7 on the photorelay is released, the squeezing force on the rubber pad 7 disappears simultaneously, Under the action of its own elastic force, it will restore its deformation and transmit the gas inside the first gas pipe 812 back to the inside of the cavity 811. At this time, through the reverse suction of the gas, the first piston rod 813 can slide synchronously into the inside of the first gas pipe 812 to complete the reset of the first piston rod 813. In this process, if the rebound function of the rubber pad 7 used fails, the gas in the first gas pipe 812 cannot be transmitted back to the inside of the cavity 811, and the first piston rod 813 cannot be reset. It will continue to stay in the extended state, and contact with the structure in the rebound failure replacement mechanism 9 in the path of ending clamping and resetting, and perform subsequent switching work on the failed rubber pad 7; like Fig. 9As shown, since a push plate 814 is fixedly arranged at the bottom of the first piston rod 813, the outer surface of the lower end of the rotating shaft 801 is annularly provided with vertical grooves 816 equidistantly, and a movable ring 815 is slidably connected between the vertical grooves 816, and the push plate 814 is arranged above the movable ring 815, in the process of the two rubber pads 7 facing each other to clamp the photorelay, the downward movement of the first piston rod 813 can drive the push plate 814 to move vertically downward synchronously, and axially push the movable ring 815 below. At this time, since the movable ring 815 is slidably arranged on the outer surface of the rotating shaft 801 through the vertical grooves 816, the movable ring 815 can move downward synchronously on the outer surface of the rotating shaft 801 Sliding, and because a first return spring 817 is fixedly arranged between the inner bottom wall of the vertical groove 816 and the movable ring 815, when the rubber pad 7 clamps the photorelay, the first piston rod 813 moves downward through the push plate 814 to push the movable ring 815 to slide downward synchronously with the outer surface of the rotating shaft 801, and the first return spring 817 is compressed synchronously. When the clamping is ended and the rubber pad 7 rebounds normally, the first piston rod 813 will return upward under the action of gas withdrawal. At this time, the downward pushing effect of the push plate 814 on the movable ring 815 disappears, and the elastic force of the first return spring 817 can drive the movable ring 815 to move upward for return to its original position for the next use; Among them, Figure 3 and Figure 4 As shown, annular grooves 803 are provided on both sides of the mounting seat 802, and a snap ring 810 adapted to the annular groove 803 is fixedly provided on one side of the mounting plate 806 facing the mounting seat 802, and the snap ring 810 is initially engaged in the annular groove 803, and a cavity 811 is provided inside the rubber pad 7, and the cavity 811 is connected to the first air pipe 812. The engagement of the snap ring 810 and the annular groove 803 can make the mounting plate 806 and the mounting seat 802 form a preliminary contact, and connect the cavity 811 and the first air pipe 812. For details, please refer to Figure 3 As shown, one end of the first gas pipe 812 facing the mounting plate 806 is coaxially arranged at the axis of the annular groove 803. When the clamping ring 810 is clamped into the annular groove 803, the end of the first gas pipe 812 can be covered, so that the gas inside the cavity 811 can be more smoothly transferred between the first gas pipe 812 and the cavity 811; Among them, Figure 3 and Figure 5 As shown, both sides of the mounting seat 802 are symmetrically provided with card slots 804, and a card block 807 adapted to the card slot 804 is symmetrically fixedly provided on one side of the mounting plate 806 facing the mounting seat 802, and the card block 807 is initially engaged in the card slot 804, and the mutual engagement between the card block 807 and the card slot 804 can further strengthen the connection between the mounting plate 806 and the mounting seat 802, thereby preventing the mounting plate 806 from loosening and separating during use; Among them, Figure 3 and Figure 6 As shown, limiting grooves 805 are symmetrically provided on both sides of the card slot 804, and a circular groove is provided on both sides of the card block 807. The first elastic telescopic column 808 is symmetrically fixedly provided on the bottom wall of the circular groove, and a limiting protrusion 809 is fixedly provided on the opposite end of the first elastic telescopic column 808. When the card block 807 is not engaged with the card slot 804, the first elastic telescopic column 808 is in an extended state, and the limiting protrusion 809 is pushed outward from the circular groove. When the card block 807 moves and is engaged with the inside of the card slot 804, it is blocked by the inner wall of the card slot 804, and the surface of the limiting protrusion 809 is squeezed (it should be noted here that the outer surface of the limiting protrusion 809 is set to a sliding surface, which can facilitate the squeezing and pushing of the limiting protrusion 809. ), the limiting protrusion 809 is squeezed and pushed back to the inside of the circular groove. At this time, the first elastic telescopic column 808 is compressed synchronously, and when the clamping block 807 continues to move to the inside of the clamping slot 804, the limiting protrusion 809 will move synchronously to the position where the limiting slot 805 is opened. Due to the increase in space, the squeezing thrust on the first elastic telescopic column 808 disappears, and the limiting protrusion 809 will be driven to move to the inside of the limiting slot 805 under the action of the elastic force, and finally the limiting protrusion 809 and the limiting slot 805 are mutually engaged, thereby further strengthening the connection between the mounting plate 806 and the mounting seat 802, so as to prevent the mounting plate 806 from being separated from the mounting seat 802 during the movement or clamping process; In the above process, by setting up the air pressure rebound monitoring mechanism 8, utilizing the cavity 811 opened inside the rubber pad 7, and cooperating with the first air pipe 812 and the first piston rod 813, during the manufacturing process of clamping the optical relay, the gas can be transmitted inside the cavity 811 and the first air pipe 812, and the feedback is applied to the first piston rod 813, so as to sense the gas flow of the rubber pad 7 when it is squeezed and released in real time, monitor the rebound function of the rubber pad 7 and realize the automation of the monitoring process, and monitor the rebound performance of the rubber pad 7 in real time without manual intervention, so as to ensure that the rubber pad 7 can fit the optical relay tightly during the clamping process, prevent loosening or slipping caused by insufficient rebound, thereby ensuring the safe and stable operation of the production, avoiding the reduction of product manufacturing accuracy due to uneven clamping, and cooperating with the rebound failure replacement mechanism 9 at the first time of detecting the failure of the rebound function, and automatically triggering the process of replacing the rubber pad 7; Please refer to the above working process Figures 1 to 9 .

[0027] The following is the working process of the rebound failure replacement mechanism 9 switching the rubber pad 7 when the rebound function of the rubber pad 7 fails: When the rebound function of the rubber pad 7 used in the above text fails, the rubber pad 7 will not be able to rebound after the clamping action is completed, and the gas transmitted to the inside of the first gas pipe 812 will no longer be able to be transmitted back to the inside of the cavity 811. At this time, the first piston rod 813 will always be in an extended state, and the push plate 814 will always resist the movable ring 815, making the movable ring 815 unable to return to its original position. As the two rubber pads 7 move in the opposite direction, the rubber pads 7 will return to their original position. Figure 1 , Figures 6 to 9 As shown, since a gear 901 is fixedly provided at the bottom of the movable ring 815, bottom plates 906 are symmetrically fixedly provided on both sides of the placement plate 101, and a connecting frame 912 is fixedly provided on the top of the bottom plate 906, and a tooth plate 913 adapted to the gear 901 is fixedly provided on the upper end of the connecting frame 912. When the clamping is completed and reset, the gear 901 will contact the tooth plate 913, and through the meshing action between the teeth, the gear 901 can be driven to rotate one hundred and eighty degrees. In the process of rotation of the gear 901, since the gear 901 is synchronously vertically slidably set on the outer surface of the rotating shaft 801 through the movable ring 815, the gear 901 can be synchronously driven to rotate on the lower surface of the fixed plate 6 when it is driven to rotate by the tooth plate 913, and the mounting seat 802 can be driven to rotate synchronously by one hundred and eighty degrees. Figure 2 As shown, rubber pads 7 are symmetrically arranged on both sides of the mounting seat 802. By driving the mounting seat 802 to rotate, the rubber pads 7 can be driven to rotate synchronously, thereby realizing the switching of the new and old rubber pads 7; Since a second air pipe 907 is fixedly provided on the top of the bottom plate 906, and a second piston rod 909 is slidably provided on the end of the second air pipe 907 away from the placement plate 101, a follower plate 910 is fixedly provided on the end of the second piston rod 909 away from the placement plate 101, and a second magnetic piece 911 is fixedly provided on the top of the follower plate 910, and since a connecting groove 902 is provided on the lower surface of the gear 901, and a connecting block 903 is slidably provided in the connecting groove 902, and a second elastic telescopic column 904 is fixedly provided on the bottom of the connecting block 903, and a first magnetic piece 905 adapted to the second magnetic piece 911 is fixedly provided on the bottom of the second elastic telescopic column 904, the gear 901 is connected to the tooth plate 911. During the process of meshing rotation and movement, the first magnetic sheet 905 will be magnetically attracted to the second magnetic sheet 911. At this time, the gear 901 continues to rotate, while the axial position of the first magnetic sheet 905 remains unchanged. It slides on the lower surface of the gear 901 through the connecting block 903 and the connecting groove 902, and resets with the axial movement of the rotating shaft 801. Under the action of the mutual magnetic attraction between the first magnetic sheet 905 and the second magnetic sheet 911, the follower plate 910 can be driven to move synchronously, and the second piston rod 909 can be pulled out from the inside of the second air pipe 907. Since a second return spring 908 is fixedly arranged between the follower plate 910 and the second air pipe 907, the second return spring 908 is sleeved on the outer surface of the second piston rod 909. When the second piston rod 909 moves outward, the second return spring 908 is stretched synchronously. Because the other end of the second gas pipe 907 is vertically slid upward with a third piston rod 914, and a top plate 915 is fixed on the top of the third piston rod 914, when the second piston rod 909 is withdrawn, the third piston rod 914 can be driven by the driving effect of the gas to slide vertically downward inside the second gas pipe 907, so that the top plate 915 moves downward synchronously. As the gear 901 continues to move until it is separated from the tooth plate 913, the rubber pad 7 can be switched. At this time, the downward movement height of the top plate 915 is lower than the height of the gear 901, and the gear 901 has also moved to the upper position of the top plate 915. At the same time, as the gear 901 continues to move, the movement range of the second piston rod 909 is limited, the first magnetic sheet 905 will lose the magnetic attraction relationship with the second magnetic sheet 911, and under the elastic force of the second reset spring 908, the second piston rod 909 can move in the opposite direction to reset. At this time, the third piston rod 914 can be driven to move vertically upward in the second gas pipe 907 through the pushing effect of the gas, and the top plate 915 can be driven to move upward synchronously to lift the gear 901, so that the first piston rod 813 extended due to the failure of the rebound can be re-slid into the first gas pipe 812, so as to facilitate the subsequent monitoring work of the first piston rod 813 connected to the new rubber pad 7; In the above process, by setting the rebound failure replacement mechanism 9, utilizing the extension of the first piston rod 813 and the meshing rotation between the gear 901 and the tooth plate 913, the rotating shaft 801 can be driven to rotate, so that the new and old rubber pads 7 on both sides of the mounting seat 802 are automatically switched, thereby realizing the process of automatically triggering the switching when the failure is detected, reducing manual intervention, and improving production efficiency and accuracy. By utilizing the rebound failure of the rubber pad 7 and enabling the mechanism to respond quickly and switch, production quality problems caused by the degradation of the performance of the rubber pad 7 can be effectively avoided. This timeliness and efficiency ensure the continuity and stability of the production line, and there is no need to stop the machine for replacement, thereby reducing downtime, improving equipment utilization and production efficiency, and ensuring that the rubber pad 7 with good performance can always be used for clamping, which helps to improve the manufacturing quality of the photorelay, reduce the scrap rate, and thus reduce the manufacturing cost; In addition, by utilizing the magnetic attraction arrangement of the first magnetic sheet 905 and the second magnetic sheet 911, and in conjunction with the second air pipe 907, the second piston rod 909, the second return spring 908, the third piston rod 914 and the top plate 915, the gear 901 can be lifted after the rotation replacement of the new and old rubber pads 7 is completed, so as to achieve the re-sliding of the first piston rod 813 that has failed in rebound, thereby ensuring the normal operation of the mechanism after the rubber pads 7 are switched; Please refer to the above working process Figures 1 to 9 .
