[0040] The specific implementation of the present invention is further described in detail below in conjunction with the accompanying drawings and examples. The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0042] The automatic pipe-taking machine of the present invention realizes accurate positioning and feeding of the exhaust pipe 11 by setting components such as the exhaust pipe feeding trough, the exhaust pipe pressing block and the exhaust pipe positioning plate, thereby improving the yield rate of the lamp tube. Specifically, the exhaust pipe arranged in the feeding trough is pushed by the output end of the exhaust pipe driving device at the rear side thereof, and moves along the exhaust pipe feeding trough to contact the exhaust pipe positioning plate at the front side thereof, and then the exhaust pipe pressing block is driven by the exhaust pipe pressing block driving device to move toward the exhaust pipe until it passes through the pressing block inlet and outlet on the side wall of the exhaust pipe feeding trough and presses the exhaust pipe against the inner wall of the exhaust pipe feeding trough, thereby realizing accurate positioning and pressing of the exhaust pipe. After the positioning is completed, the exhaust pipe positioning plate is driven by the positioning plate lifting device to descend to a predetermined position, and at the same time, the mounting base block is driven by the mounting base block driving device to move toward the front side of the bulb in the direction close to the bulb, and after the front end of the exhaust pipe is heated and melted, the mounting base block driving device continues to push the mounting base block and the exhaust pipe and other components to move toward the bulb until the exhaust pipe contacts and communicates with the bulb. After the exhaust pipe is connected to the light bulb, each component returns to its original position to wait for the connection of the next exhaust pipe. Among them, the exhaust pipe feed trough can be realized by setting two rectangular plates 2021 on the surface of the mounting base block, and the inlet and outlet of the clamping block are realized by opening a rectangular notch on one of the rectangular plates. The exhaust pipe driving device, the mounting base block driving device and the positioning plate lifting device are all linear displacement driving devices with linear displacement driving function, which can be a cylinder, an oil cylinder, an electric cylinder, etc., and a cylinder is preferably used here. In this embodiment, the exhaust pipe driving device is composed of a cylinder 2031 and an exhaust pipe positioning push block 2032 at the output end of the cylinder. The exhaust pipe positioning push block is L-shaped, and an exhaust pipe ejector pin 2033 is provided at its front end. One end of the exhaust pipe ejector pin is located in the receiving groove on the surface of the exhaust pipe positioning push block, and between the bottom surface of the receiving groove and the exhaust pipe ejector pin. A compression spring 2034 is provided. During positioning, the exhaust pipe positioning plate at the front end of the exhaust pipe is driven by the cylinder below it to move upward, and the exhaust pipe positioning push block is driven by the cylinder to move forward. The exhaust pipe ejector pin pushes the exhaust pipe forward under the drive of the exhaust pipe positioning push block, so that it contacts the exhaust pipe positioning block at the front end. Thereafter, the wedge-shaped driving block contacts the charging cylinder and presses it under the drive of the cylinder. After the exhaust pipe is pressed, the exhaust pipe positioning block is driven by the cylinder to descend to its original position. At this time, the position of the exhaust pipe is the starting position of the exhaust pipe connecting pipe.In addition, the clamping block driving device can directly drive the clamping block to clamp the exhaust pipe by means of linear displacement driving, or indirectly push the clamping block to clamp the exhaust pipe by means of a connecting rod and its lever principle. In this embodiment, the clamping block driving device includes a clamping cylinder 2051 arranged on the mounting base block, and a wedge-shaped driving block 2052 located at the output end of the clamping cylinder. The exhaust pipe clamping block is arranged at the end of the connecting rod 2053, which is integrally formed with the connecting rod. A connecting column 2054 is provided at the other end of the connecting rod. The middle part of the connecting rod can be rotatably arranged on the mounting base block, and a spring 2055 can be arranged between the connecting rod and the mounting base block. One end of the spring is arranged at one end of the connecting rod away from the exhaust pipe clamping block, and the other end is arranged on the mounting base block. The spring can clamp one end of the connecting rod, thereby causing the exhaust pipe clamping block located at the other end to rotate outward, thereby loosening the exhaust pipe. During specific operation, the wedge-shaped driving block moves toward the connecting column under the drive of the clamping cylinder. After the inclined surface of the wedge-shaped driving block contacts the connecting column, the clamping cylinder continues to push the wedge-shaped driving block forward. At this time, the connecting column rotates outward under the push of the wedge block, thereby causing the connecting rod to rotate. The clamping block at the other end of the connecting rod moves toward the exhaust pipe until the clamping block clamps the exhaust pipe. To loosen the exhaust pipe, you only need to move the wedge block in the opposite procedure.

[0043] Preferably, in the automatic take-over machine of this embodiment, the exhaust pipe feeding assembly also includes a vertical substrate 102, the mounting base block is slidably arranged on the vertical substrate, the mounting base block driving device includes a driving motor 1011 whose body is arranged on the vertical substrate, the output shaft of the driving motor is connected to the central axis of the driving wheel 1012, and a driven wheel 1013 is also arranged on the vertical substrate, a transmission belt 1015 is wound around the driving wheel and the driven wheel, a connecting seat 1014 is fixedly connected to the transmission belt, and the connecting seat is fixedly connected to the mounting base block.

[0044] The setting of the vertical mounting plate realizes the support and installation of the mounting base block, the driving motor and other components, wherein the setting of the driving motor, the driving wheel, the driven wheel and other components realizes the driving of the mounting base block. During specific operation, the output shaft of the driving motor drives the driving wheel to rotate, thereby driving the transmission belt wrapped around the driving wheel and the driven wheel to rotate around the driving wheel and the driven wheel, and makes the connecting seat connected to the transmission belt move along the direction of the transmission belt, and finally realizes the lateral driving function of the mounting base block and the upper exhaust pipe. Among them, the vertical base plate includes an upper base plate 1021 and a lower base plate 1022, which are connected by bolts to achieve the adjustable height, and a horizontal base plate 103 can be set at the bottom end of the lower base plate to make the whole device more stable. In addition, the body of the positioning plate lifting device is fixed on the vertical plate, and its output end is connected to the exhaust pipe positioning plate through a support block 303, and the support block can be slidably set on the guide rail on the vertical base plate. A switch 104 may also be provided at the rear end of the vertical substrate. The switch is a travel switch or a photoelectric switch, which is used to determine the starting position of the push-tube pressing assembly docking with the bulb, so as to calculate the docking distance of the exhaust pipe. The relative distance of docking is input through a touch screen or text, which is convenient for operators to adjust data according to different specifications of bulbs.

[0045] Preferably, the automatic taking over machine of the present embodiment is further provided with a transverse mounting plate 105 on the top of the vertical base plate, a feeding plate 106 and a feeding plate driving device 107 for driving the feeding plate to move are slidably provided on the surface of the transverse mounting plate, a feeding hole 108 penetrating the feeding plate along the thickness direction thereof is provided on the surface of the feeding plate, a feeding hopper 109 is further provided above the feeding plate, and an output port of the feeding hopper is located above the feeding hole.

[0046] The arrangement of the feeding plate, feeding hopper and other components realizes the automatic and continuous feeding of the exhaust pipe. During specific operation, the exhaust pipe in the feeding hopper falls into the feeding hole below it under the action of gravity, and then the output end of the feeding plate driving device drives the feeding plate to move along the guide rail on the surface of the transverse mounting plate until the feeding hole moves to the top of the exhaust pipe feeding trough. At this time, the exhaust pipe in the feeding hole falls into the exhaust pipe feeding trough under the action of gravity, and then the output end of the feeding plate driving device drives the feeding plate to return to its original position to wait for the next feeding. The feeding plate driving device is preferably a cylinder, and its cylinder body is fixed on the transverse mounting button. The feeding hopper is fixedly connected to the transverse mounting plate through a plate, and there is a gap between its bottom end and the transverse mounting plate, and the gap can just accommodate the feeding plate.

[0047] Preferably, the automatic take-over machine of this embodiment further includes an exhaust pipe heating device 4, which includes a mounting frame 401 and a mounting ring 402 located at the front side of the output end of the exhaust pipe feeding assembly, and a plurality of combustion tubes 403 are provided on the mounting ring.

[0048] The exhaust pipe heating device is set to heat the exhaust pipe so that it is in a molten state, which is convenient for connecting with the light bulb. In specific operation, the exhaust pipe is transported by the exhaust pipe feeding assembly to the center of the mounting ring, and then the flames ejected from the ends of the multiple combustion pipes burn the ends of the exhaust pipe. After the ends are melted, the heating is stopped, and the exhaust pipe continues to move toward the light bulb under the drive of the exhaust pipe feeding assembly.

[0049] Preferably, the automatic takeover machine of this embodiment further includes a bulb testing device 5, which includes a test frame 501, an upper slider 502 and a lower slider 503 slidably arranged on the test frame, a slider driving device 504 for driving the upper slider or the lower slider to move, an upper pressing block 505 connected to the upper slider, and a lower pressing block 506 connected to the lower slider, the upper pressing block is located directly above the lower pressing block, and a connecting cavity is provided in the upper pressing block or the lower pressing block, one end of the connecting cavity is connected to the input end of the gas pressure sensor 507, and the other end of the connecting cavity can be connected to the inner cavity of the bulb, and the bulb testing device also includes an input tube 508.

[0050] The setting of the bulb testing device realizes the detection of the bulb. When the bulb leaks due to the large docking hole, that is, the ignited coal gas and oxygen mixture heats the lamp tube through the welding nozzle and inflates and punches a hole in the bulb, or when the lamp tube fails to be broken due to unstable coal oxygen gas pressure, components such as the exhaust pipe feeding assembly located downstream thereof will not operate, thereby saving production costs. During specific operation, when the light bulb is transported to the predetermined workstation, the upper slider and the lower slider move toward each other under the drive of the slider driving device until the upper slider drives the upper pressure block to move to the top of the light bulb, and the lower slider drives the lower pressure block to move to the bottom of the light bulb. At this time, the lower pressure block seals the bottom end of the light bulb, and the end face of the upper pressure block seals the top of the light bulb. The connecting cavity is connected to the inner cavity of the light bulb. At this time, the input tube is just located in the connecting hole in the middle of the light bulb, and the gas is gradually inflated into the light bulb through the connecting hole. As the input tube is inflated, the air pressure inside the light bulb gradually increases, and the gas pressure sensor connected to the inner cavity of the light bulb through the connecting cavity gradually senses the increase in pressure. If the light bulb is not leaking, the gas pressure sensor will sense the predetermined pressure value. If the light bulb is leaking, the gas pressure in the light bulb cannot reach the predetermined pressure value, and the controller connected to the gas pressure sensor can judge whether the light bulb is leaking through the pressure value. Among them, the gas pressure sensor is installed on the top of the test frame through the L plate, and the slider driving device is a cylinder, whose cylinder body is fixed on the top of the test frame, and its output end is connected to the upper slider, and the upper slider is connected to the lower slider through the rack and gear assembly, so that the upper slider and the lower slider can be linked. Specifically, when the upper slider moves, the rack on the upper slider drives the gear to rotate, and then another rack meshing with the gear and set on the lower slider drives the lower slider to move in the opposite direction. The upper pressing block and the lower pressing block move with the upper slider and the lower slider respectively through the connecting rod, and the connecting cavity is set in the upper pressing block, and a vent hole is set at the bottom to achieve communication with the inner cavity of the bulb. The input pipe is set on the exhaust pipe mounting seat 509 through the L seat.

[0051] Preferably, the automatic take-over machine of this embodiment further includes a workbench 10, a plurality of bulb clamping fixtures 7 arranged on the workbench and a workbench driving device for driving the workbench to rotate, the bulb clamping fixture includes a support 701, two mounting shafts 702 rotatably arranged on the support, a clamping block 703 with one end arranged on the mounting shaft, a reset rod 704 is arranged at one end of the mounting shaft, an operating rod 705 is arranged at the other end of one of the two mounting shafts, a compression spring (not shown in the figure) is also arranged between the two reset rods, and the two mounting shafts are meshed by teeth.

[0052] The setting of the workbench enables multiple bulb clamping fixtures to rotate around the center under the drive of the workbench, so that each bulb can be operated in each process in turn. The setting of the bulb clamping fixture realizes the clamping of the bulb, which is convenient for taking over the operation. During the specific operation, the end of the operating rod rotates outward under the action of manual or pneumatic force, thereby driving a mounting shaft to rotate. As the mounting shaft rotates, another mounting shaft meshing with the mounting shaft through teeth also rotates outward, thereby driving the clamping block to rotate, thereby separating the two clamping blocks. Subsequently, the bulb is set between the two clamping blocks by manual or claw hands. After the bulb is stable, the operator or the cylinder releases the operating rod. As the operating rod is released, the compression spring located between the two reset rods drives the reset rod and the mounting shaft connected thereto to rotate in the opposite direction mentioned above, thereby closing the two clamping blocks, so that the bulb is clamped between the two clamping blocks. The support is an L-shaped support, and two plates for installing the mounting shaft are respectively arranged at the upper and lower ends of the vertical plate of the L-shaped support, and the two ends of the mounting shaft are rotatably arranged on the upper and lower plates, respectively. The reset rod is arranged at the top of the mounting shaft, and the operating rod is arranged at the bottom of one of the mounting shafts. When working, the operating rod is rotated by the push of the cylinder. The number of bulb clamping fixtures can be set according to needs, and multiple bulb clamping fixtures are evenly distributed at the edge of the circular workbench surface, and the workbench driving device can be a stepping motor.

[0053] Preferably, the automatic take-over machine of this embodiment further includes a bulb loading assembly 8, which includes a loading seat 801, a loading rod 802 rotatably disposed on the loading seat, a loading drive rod 804 connected to the rotating shaft 803 of the loading rod, and a loading cylinder 805 whose output end is hinged to the loading drive rod, one end of the loading rod is fixedly connected to the rotating shaft, and the other end is provided with a bulb clamping device, which includes a clamping seat 806 disposed at the end of the loading rod, a bulb clamping cylinder 807 whose cylinder body is fixedly disposed on the clamping seat, and a bulb clamping plate 808 connected to the output shaft of the bulb clamping cylinder.

[0054] The arrangement of the feeding rod, feeding drive rod, feeding cylinder and bulb clamping device realizes the feeding operation of bulbs. During specific operation, the bulb clamping cylinder drives the bulb clamping plate to move toward the clamping seat until it clamps the bulb between the bulb clamping plate and the clamping seat. Subsequently, the output end of the feeding cylinder drives the feeding rod and the rotating shaft to rotate. As the rotating shaft rotates, the feeding rod fixed to the rotating shaft also rotates until the feeding rod rotates to a vertical position. At this time, the bulb originally arranged horizontally on the clamping seat is arranged vertically between the two clamping blocks of the bulb clamping fixture. Finally, the bulb clamping fixture clamps the bulb. After the bulb is clamped, the bulb clamping cylinder releases the bulb and returns to its original position, thereby realizing automatic feeding of the bulb. Among them, a V-shaped positioning groove 809 is arranged at the end of the bulb clamping plate. When clamped, the bulb is located in the V-shaped positioning groove.

[0055] Preferably, in the automatic take-over machine of this embodiment, the bulb loading assembly also includes a material trough assembly, the material trough assembly includes a material trough 810 for placing the bulb, a top block 811 arranged between the output end of the material trough and the bulb clamping device, a top block lifting device 812 for driving the top block to rise and fall, and positioning hooks 813 located on both sides of the clamping seat, the top surface of the top block is an inclined surface, and the positioning hooks are arranged at the output end of the material trough.

[0056] The setting of the trough assembly realizes the storage and automatic loading of the bulbs, thereby further improving the automation and efficiency of bulb loading. During specific operation, the bulb set at the output end of the trough contacts the side of the positioning hook, and the side of the positioning hook can prevent the bulb from rolling out of the trough. At this time, the bulb located at the output end is just above the top block. During loading, the top block rises under the action of the top block lifting device until the bulb is lifted to a position above the positioning hook. The top surface of the positioning hook is the bulb groove 814. Since the top surface of the top block is an inclined surface, when the bulb is lifted to the top of the positioning hook, the bulb rolls down to the bottom of the bulb groove of the positioning hook along the inclined surface of the top block under the action of weight. At this time, the bulb is just between the clamping seat and the bulb clamping plate. Then the bulb clamping device clamps the bulb and completes the loading of the bulb in the above manner. At the same time, the top block returns to its original position to wait for the next loading. The top block lifting device is a cylinder. The trough may be provided with a roller 815, and the gap between the roller and the bottom surface of the trough allows only one bulb to pass through at a time, thereby preventing multiple bulbs from being stacked at the output end of the trough. In addition, the trough may be displaced in three dimensions by a three-dimensional platform 816 to adapt it to the bulb clamping device.

[0057] Preferably, the automatic pipe taking-over machine of this embodiment further includes a waste pipe detection assembly 9, which includes a probe 901, a probe lifting device 902 for driving the probe to lift and lower, a discharge device 903 electrically connected to the probe, a detection brush 904 located under the probe, and a controller electrically connected to the detection brush.

[0058] When taking over the pipe, some exhaust pipes are not completely aligned with the bulb, resulting in air leakage between the exhaust pipe and the bulb, which in turn causes waste. The waste pipe detection component can detect the waste pipe and distinguish it from the finished product. During specific operation, the probe is driven by the probe lifting device to extend from the top opening of the bulb into the inside of the bulb until its bottom reaches the connection between the bulb and the exhaust pipe. At this time, the detection brush is set on the outside of the connection between the bulb and the exhaust pipe. Then the discharge device electrically connected to the probe puts the probe in a high-voltage state. If there is a gap at the connection between the bulb and the exhaust pipe, an electric spark will be generated between the detection brush made of metal wire in contact with the bulb and the probe. The controller electrically connected to the detection brush, preferably a PLC, can detect the electric spark according to the change in voltage, thereby determining that the bulb is waste. The probe lifting device is preferably a cylinder, and the discharge device, probe, detection brush and probe lifting device are all installed on the detection frame 905.

[0059] Preferably, the automatic taking-over machine of this embodiment further includes a unloading assembly 6, which includes a claw device and a unloading device, the claw device includes a unloading slide 601, a pneumatic claw 602 arranged above the unloading slide, a claw rotation drive device 603 for driving the pneumatic claw to rotate, and a unloading slide drive device 604 for driving the unloading slide to move along the guide rail on the surface of the workbench, the unloading device includes a unloading trough 605, a transmission hole 607 is arranged on the bottom surface of the unloading trough, and a lifting bracket 608 and a bracket drive device 609 for driving the lifting bracket to rise and fall are arranged below the transmission hole.

[0060] The setting of the claw device realizes the purpose of unloading the finished product from the bulb clamping fixture and inputting it into the unloading device, and the setting of the unloading device realizes the output of the finished product. Specifically, the pneumatic claw hand grabs the bulb on the bulb clamping fixture under the drive of the cylinder, and the bulb clamping fixture releases the bulb at the same time. Then the unloading slide moves to the unloading device under the drive of the unloading slide driving device. Thereafter, the claw hand rotation driving device drives the claw hand to rotate until the bulb is in a horizontal position. At this time, the bulb is just located at the top of the lifting bracket. Then the pneumatic claw hand releases the bulb, and the lifting device descends until it descends to the bottom of the transmission hole. Then the bulb falls off from the top of the lifting bracket to the unloading trough and slides along the unloading trough into the output frame. The pneumatic claw hand drives the connecting shaft 610 to move through the cylinder. As the connecting shaft moves, the rectangular hole 611 at one end and the finger 612 on the connecting shaft move accordingly and open or close, thereby realizing the clamping of the bulb. The middle part of the finger is hinged on the fixed seat 613 where the cylinder is installed. In addition, the claw hand rotation drive device is a cylinder, which realizes the rotation drive of the pneumatic claw hand in a manner similar to the loading method of the light bulb loading assembly. Its specific structure and principle are not repeated here.
