[0018] The present invention drives the speaker grinding column on the other side of the top end of the pressure seesaw to be tilted, and guides and smoothly moves upward under the limit of another limit sleeve rod.

In this way, the rubber block is not sufficient to continue to limit the downward movement of the screw hole telescopic plate, so that the second screw rod is rotated and wrapped with the hemp rope. The pulled hemp rope will generate friction with the speaker grinding column, driving the speaker grinding column to rotate, and the inner wall of the top end of the rotating speaker grinding column can rotate and rub the outer wall of the bottom end of the glass ball bulb tube, so that the bottom end is smooth after rotation and grinding while the residual heat has not yet been fixed.

[0031] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0032] like Figures 1 to 8As shown, the present invention provides a firing and sealing device for a filament lamp bulb, comprising a firing device 1, a LOGO printing device 2 is provided on the side of the firing device 1, the sealing portion 3 is fixedly connected between the firing device 1 and the sealing portion 3, a mechanical arm 11 is fixedly connected to the top outer wall of the sealing portion 3, and a glass bulb tube 12 can be intermittently attached and adsorbed on the bottom of the other end of the mechanical arm 11, the sealing portion 3 includes an L-shaped arc support plate 31, and two ear plates 32 are provided on the side wall of one end of the sealing portion 3, A forward and reverse rotating motor 33 is fixedly connected to the outer wall of one end of an ear plate 32, a bidirectional threaded rod 34 is fixedly connected to the rotating shaft of the motor 33, two sections of the bidirectional threaded rod 34 are respectively connected to the plate bodies of the two ear plates 32 for through rotation, and clamping plates 35 are threadedly connected to the rod bodies of the two ear plates 32 on both sides of the bidirectional threaded rod 34, the two clamping plates 35 are symmetrical to each other, and a T-shaped stopper 37 is provided at one symmetrical end of the two clamping plates 35, and a movable grinding structure is jointly provided on a group of clamping plates 35;

[0033] A rectangular groove 36 is respectively provided in one end of the two clamps 35, and the inner wall of the rectangular groove 36 is fitted and slidably connected to the outer wall of the T-shaped retaining piece 37. Two springs 38 are fixedly connected to the smooth outer wall of one end of the T-shaped retaining piece 37, and the other ends of the two springs 38 are fixedly connected to the inner wall of one end of the rectangular groove 36. Rubber blocks 39 are fixedly connected to the outer walls of both ends of the T-shaped retaining piece 37, and L-shaped sliding grooves 340 that can be fitted and slidably engaged with the two rubber blocks 39 are provided in the inner walls of both ends of the clamps 35.

[0034] The above scheme is adopted: the motor 33 is started to drive the two-way threaded rod 34 to rotate, thereby driving the two clamping plates 35 to move in opposite directions on the two-way threaded rod 34. During the movement process, the two clamping plates 35 will be blocked by the L-shaped arc support plate 31 and can only move horizontally. Then, the two clamping plates 35 that move horizontally will synchronously drive the T-shaped abutting pieces 37 to move horizontally until they contact the tube body of the glass bulb tube 12 and abut it again at a unified position to avoid the situation where the tube bodies of the glass bulb tubes 12 are of different lengths and bottom shapes. After the abutting operation, the two T-shaped abutting pieces 37 will continue to move passively horizontally on the clamping plates 35. When they press against each other to generate an extrusion force, they will slide in the L-shaped sliding groove 340 through the rubber blocks 39 installed at both ends, and the sliding process will also synchronously squeeze the two springs 1 38 until the rubber block 39 and one end of the L-shaped sliding groove 340 are clamped and limited.

[0035] The mobile grinding structure includes two rectangular slots 341 opened on one end of the L-shaped arc support plate 31, and the inner walls of the two rectangular slots 341 are movably sleeved with screw rods 342, and the inner walls of the bottom ends of the two rectangular slots 341 are fixedly connected with springs 343, and the top ends of the two springs 343 are respectively fixedly connected to the bottom outer walls of the two ear plates 32, and the two clamping plates 35 are fitted and slidably connected to one end of the L-shaped arc support plate 31, and the top side wall of the L-shaped arc support plate 31 is fixedly connected with a pressure plate 344. A telescopic rod 345 is fixedly connected to the side wall of the bottom end of the pressure plate 344, and the bottom of the telescopic rod 345 is movably connected to the middle rod body of the two-way threaded rod 34. A group of arc grooves 346 are opened on the outer walls at both ends of the bottom of the pressure plate 344, and the inner wall of each group of arc grooves 346 can be correspondingly slidably connected with a ball 348. A guard plate 347 is movably connected to the two groups of ball rollers 348 respectively, and the bottom side walls of the two guard plates 347 are fixedly connected to the top outer walls of the two clamps 35 respectively.

[0036] The above scheme is adopted: when the clamping plate 35 is passively and continuously translated to make the two T-shaped abutting pieces 37 press against each other, it will also synchronously drive the fence 347 to contact the arc groove 346 opened on the outer wall of the pressing plate 344, and the ball 348 installed on one end of the fence 347 can smoothly slide along the inner wall path of the arc groove 346 under the application of external force, thereby generating a motion trajectory that gradually moves vertically downward while moving horizontally, which can link the two clamping plates 35 to move downward synchronously, and this process will drive the two ear plates 32 and the motor 3 3. The bidirectional threaded rod 34 moves downward synchronously, thereby stretching the telescopic rod 345 on the pressure plate 344 to extend the rod body. When the two ear plates 32 passively move downward, the corresponding screw rod 1 342 will be driven to rotate in place in the rectangular slot 341, and the downward movement process will squeeze the spring 2 343, which will facilitate the subsequent reset of the splint 35 and other structures. The threaded engagement force between the screw rod 1 342 and the ear plate 32 is sufficient to support the support limit of the relevant structure without additional external force.

[0037] A screw hole expansion plate 349 is jointly and fixedly connected to the outer wall at the bottom end of the two clamping plates 35, and a pressure rocker plate 350 is provided below the screw hole expansion plate 349. A ball shaft rod frame 351 is movably sleeved in the center of the pressure rocker plate 350, and a screw rod 352 with a ball shaft bottom and a horn grinding column 353 are movably sleeved on the outer walls on both sides of the top end of the pressure rocker plate 350. A rubber block is fixedly connected to the top of the screw rod 352. A limiting sleeve rod 354 is slidably sleeved on the rod bodies of the horn grinding column 353 and the screw rod 352. The rod bodies of the two limiting sleeve rods 354 are inconsistent in shape, and one end of the rod bodies of the two limiting sleeve rods 354 are fixedly connected to the outer wall of one end of the L-shaped arc support plate 31. The screw rod 352 and the screw hole expansion plate 349 can be intermittently threaded, and the rubber block can be intermittently fitted and slidably connected with the screw hole in the screw hole expansion plate 349.

[0038] The above scheme is adopted: when the two splints 35 translate in opposite directions, the screw hole expansion plate 349 will be synchronously driven to shrink the plate body, thereby synchronously driving the connected screw hole expansion plate 349 to move downward together until it contacts the rubber block on the top of the screw rod 352. Under the isolation of the rubber block, it will first be driven downward by the downward-moving screw hole expansion plate 349, thereby being guided and smoothly moved downward under the limit of a limit sleeve rod 354, and under the application of external force, it can drive the pressure rocker plate 350 to tilt with the ball shaft rod frame 351 as the axis point.

[0039] A group of limit plates 355 are also fixedly connected to the rod bodies of the speaker grinding column 353 and the second screw 352, and a hemp rope 356 is fixedly connected between the speaker grinding column 353 and the rod bodies of the second screw 352. A torsion spring 357 is fixedly connected to the outer wall of a limit plate 355 near the bottom of the speaker grinding column 353, and the bottom end of the torsion spring 357 is fixedly connected to the top side wall of the pressure rocker 350. The top inner wall of the speaker grinding column 353 can be intermittently fitted and rotatably connected to the bottom outer wall of the glass ball bulb tube 12, and the two T-shaped abutments 37 can also be intermittently fitted and connected to the bottom outer wall of the glass ball bulb tube 12.

[0040] The above scheme is adopted: the tilting of the pressure rocker 350 drives the speaker grinding column 353 on the other side of its top, and it is guided and smoothly moved upward under the limit of another limit sleeve 354. The upward moving speaker grinding column 353 will squeeze through the two T-shaped abutments 37, so that one end of the abutment of the two T-shaped abutments 37 fits the outer wall of the column of the speaker grinding column 353, thereby contacting the bottom outer wall of the glass ball bulb tube 12. At this time, the tilting of the pressure rocker 350 also presents a maximum angle and can no longer continue to tilt. In this way, the rubber block is not enough to continue to limit the downward movement of the screw hole expansion plate 349, so that the screw rod 2 352 is rotated and wrapped with the hemp rope 356. The pulled hemp rope 356 will generate friction with the speaker grinding column 353, driving the speaker grinding column 353 to rotate, and the inner wall of the top of the rotating speaker grinding column 353 can rotate and rub the outer wall of the bottom end of the glass ball bulb tube 12, so that the bottom end is smooth after rotation and grinding while the residual heat has not yet been fixed.

[0041] One point that needs to be added is that after the two T-shaped push pieces 37 have just cut the glass bulb tube 12, the railing 347 will also move downward under the pressure of the pressure plate 344, thereby driving the two T-shaped push pieces 37 and the glass bulb tube 12 to separate. The cut glass tube body needs to be picked up manually using auxiliary tools to avoid affecting the subsequent work process. As a result, the speaker grinding column 353 has been passively moved upward and pressed through the two T-shaped push pieces 37. At this time, the two T-shaped push pieces 37 have not yet been clamped into the L-shaped sliding groove 340 through the rubber clamp block 39.

[0042] The working principle and use process of the present invention are as follows: after the glass bulb tube 12 is adsorbed by the robot arm 11 in the prior art through system control, the glass bulb tube 12 that has been burned is driven to move upward, thereby burning and cutting off the glass tube body at the bottom. This is the operation process in the prior art, and its movement principle and specific operation process will not be described in detail here. Then, it will be transferred to the LOGO printing device 2 through rotation, and it will pass through the sealing part 3 and stop. At that time, the motor 33 starts to drive the bidirectional threaded rod 34 to rotate, thereby driving the two clamps 35 to move in opposite directions on the bidirectional threaded rod 34, and its movement process will pass through an L-shaped arc. The two clamping plates 35 which move in parallel with each other will synchronously drive the T-shaped abutting pieces 37 to move in parallel until they contact the tube body of the glass bulb tube 12, and abut against it again at a uniform position to avoid the situation that the tube bodies of the glass bulb tubes 12 are of different lengths and bottom shapes. After the abutting operation, the two T-shaped abutting pieces 37 will continue to move passively in parallel on the clamping plates 35. When the two T-shaped abutting pieces 37 press against each other to generate an extrusion force, they will slide in the L-shaped sliding groove 340 through the rubber clamping blocks 39 installed at both ends, and the sliding process will also synchronously squeeze the two springs 1 38 until the rubber clamping block 39 and one end of the L-shaped sliding groove 340 are clamped and limited.

[0043] When the clamping plate 35 passively and continuously translates to make the two T-shaped pressing pieces 37 press against each other, it will also synchronously drive the fence 347 to contact the arc groove 346 opened on the outer wall of the pressing plate 344. The ball 348 installed on one end of the fence 347 can slide smoothly along the inner wall path of the arc groove 346 under the application of external force, thereby generating a motion trajectory that translates horizontally and gradually moves vertically downward, which can link the two clamping plates 35 to move downward synchronously. This process will drive the two ear plates 32, the motor 33, and the two-way threaded rod 34 to move downward synchronously, thereby stretching the telescopic rod 345 on the pressing plate 344 to extend the rod body, The process of plate 32 passively moving downward will drive the corresponding screw rod 1 342 to rotate in place in the rectangular slot 341, and the downward movement process will squeeze the spring 2 343, which will facilitate the subsequent reset of the clamping plate 35 and other structures through the spring 2 343. The threaded engagement force between the screw rod 1 342 and the ear plate 32 is sufficient to support the support and limit of the relevant structures without additional external force. When the two clamping plates 35 move in opposite directions, the screw hole expansion plate 349 will be synchronously driven to shrink the plate body, thereby synchronously driving the connected screw hole expansion plate 349 to move downward together until it contacts the rubber block on the top of the screw rod 2 352. , first, it will be driven downward by the downwardly moved screw hole expansion plate 349, thereby being guided and smoothly moved downward under the limit of a limit sleeve rod 354, and under the application of external force, it can drive the pressure rocker 350 to tilt with the ball shaft rod frame 351 as the axis point, thereby driving the speaker grinding column 353 on the other side of the top of the pressure rocker 350 to be guided and smoothly moved upward under the limit of another limit sleeve rod 354, and the upwardly moved speaker grinding column 353 will squeeze through the two T-shaped abutments 37, so that one end of the abutment of the two T-shaped abutments 37 fits the outer wall of the column of the speaker grinding column 353, thereby contacting the outer wall of the bottom end of the glass ball bulb tube 12, which When the rocker plate 350 is tilted, it also shows the maximum angle and cannot tilt any further. Thus, the rubber block is not enough to continue to limit the downward movement of the screw hole expansion plate 349, so that the screw rod 352 is rotated and wrapped with the hemp rope 356. The pulled hemp rope 356 will generate friction with the speaker grinding column 353, driving the speaker grinding column 353 to rotate. The inner wall of the top of the rotating speaker grinding column 353 can rotate and rub the outer wall of the bottom end of the glass bulb tube 12, so that the bottom end of the glass bulb tube 12 becomes smooth after rotation and grinding while the residual heat has not yet been fixed. This prevents the bottom end of the glass tube from being stretched and causing wire drawing or bottom deformation.
