Description

Technical Field

[0001] This utility model relates to the field of glass production equipment technology, and in particular to a fully automatic stemmed glass welding machine. Background Technology

[0002] A stemmed glass is an elegant and beautiful glass vessel, typically used for drinking red wine or champagne. Generally, the manufacturing process involves separately manufacturing the glass body and stem, then welding them together at high temperatures to form the stemmed glass we commonly see in daily life. Welding of stemmed glasses is usually achieved using a glass welding machine. Currently available stemmed glass welding equipment typically has two rotating turntables, one for the glass body and the other for the stem. During welding, the glass body and stem are brought close together, and a torch is used to heat the joint between them, melting the glass body and welding it together.

[0003] Because the existing stemmed glass welding machine has two continuously rotating turntables that support the stem and the body of the glass respectively, it is necessary to ensure uniform heating at the connection between the body and the stem in order to ensure the welding effect. To this end, the torch used for heating needs to swing back and forth at the welding station and several stations before and after the welding station to ensure uniform heating. This requires a mechanism to drive the torch to swing back and forth, which makes the equipment structure more complicated. Moreover, the reciprocating movement will increase the speed of aging and damage of the pipes connected to the torch and increase the risk of detachment, affecting the service life of torch accessories and posing safety hazards.

[0004] The technical problem to be solved by this utility model is: how to solve the problems of complex structure and high wear and tear of parts in existing goblet welding equipment. Utility Model Content

[0005] In order to overcome the shortcomings of the existing technology, the purpose of this utility model is to provide a fully automatic stemmed glass welding machine, which has the characteristics of simple and compact structure, high safety performance and low component wear.

[0006] The technical solution adopted by this utility model is as follows: a fully automatic stemmed glass welding machine, including a frame and a welding mechanism installed on the frame. The frame includes a base, a lower turntable and an upper turntable arranged sequentially from bottom to top. The lower turntable and the upper turntable are rotatably connected to the base. The base is provided with a turntable power component for driving the lower turntable and the upper turntable to rotate synchronously and intermittently.

[0007] The welding mechanism includes several lower support seats, several upper clamp seats, several torches, and a lower cross plate. Each lower support seat is rotatably mounted on the lower turntable at intervals along its circumference. Each upper clamp seat is rotatably mounted on the upper turntable at intervals along its circumference. Each lower support seat corresponds to each upper clamp seat. The lower cross plate is located at the bottom of the lower turntable and extends along the rotation trajectory of the lower turntable. The top structure of the lower cross plate is high in the middle and low at both ends. Each torch is rotatably mounted on the side of the lower turntable at intervals along its circumference and is located above the lower cross plate.

[0008] The fully automatic stemmed glass welding machine of this application sets the lower and upper turntables to rotate intermittently. That is, the lower and upper turntables rotate at a preset angle and then pause for a certain period of time, but the lower support and upper clamp always maintain synchronous rotation. The advantage of this design is that the position and duration of the pause of the lower and upper turntables can be set according to the position of the torch and the rotation speed of the lower support and upper clamp. This allows the lower support and upper clamp to drive the stem and body of the cup to rotate while the torch remains stationary, so that the welding joint between the stem and the body of the cup is heated evenly, ensuring the welding quality. Moreover, since the torch remains stationary during operation, the risk of the pipes connected to the torch falling off or breaking can be reduced, thereby extending the service life of the parts and improving safety.

[0009] In some embodiments, the frame also includes a central shaft and a connecting flange. One end of the central shaft is fixed to the base, and the other end is successively connected to the lower turntable and the upper turntable. The two ends of the connecting flange are respectively connected to the lower turntable and the upper turntable. The lower turntable, the upper turntable and the connecting flange all rotate around the central shaft.

[0010] By adopting the above technical solution, the lower turntable and the upper turntable are connected by a connecting flange, which can ensure that the lower turntable and the upper turntable rotate synchronously. By setting a central shaft, the upper turntable and the lower turntable are connected to the central shaft by bearings, which can make the rotation of the upper turntable, the lower turntable and the connecting flange more stable.

[0011] In some embodiments, a rotary drive mechanism is also included to drive the rotation of each lower support and each upper clamp. The rotary drive mechanism includes a rotary power component, a driving wheel, a first driven wheel, and a second driven wheel. The rotary power component is mounted on a central shaft. The driving wheel is drivenly connected to the output end of the rotary power component and is coaxial with the central shaft. The first driven wheel is mounted on an upper turntable, and the second driven wheel is mounted on a lower turntable. The first driven wheel is drivenly connected to the driving wheel and the first driven wheel is connected to the second driven wheel through a synchronous shaft. Each upper clamp is provided with a first driven wheel that is drivenly connected to the first driven wheel, and each lower support is provided with a second driven wheel that is drivenly connected to the second driven wheel.

[0012] By adopting the above technical solution, this setup can drive multiple lower support seats and multiple upper clamp seats to rotate synchronously through a single rotating power component and a synchronous shaft. On the one hand, it can save the number of power components and reduce costs. On the other hand, it can ensure that the lower support seats and upper clamp seats can rotate synchronously, ensuring the welding effect. In addition, by setting the drive wheel on the center of the central shaft, it can ensure that the center distance between the drive wheel and the first driven wheel and the second driven wheel remains unchanged during the rotation of the upper and lower turntables, ensuring smooth power transmission and improving transmission accuracy.

[0013] In some embodiments, a transition wheel is also provided on the synchronous shaft. The transition wheel is connected to the driving wheel via a first chain drive, the first driven wheel is connected to each of the first driven wheels via a second chain drive, and the second driven wheel is connected to the second driven wheel via a third chain drive.

[0014] By adopting the above technical solution, chain drive can ensure transmission accuracy and avoid slippage during transmission. Moreover, chain drive has a certain degree of flexibility, which can improve the fault tolerance rate, reduce assembly requirements, and help reduce costs.

[0015] In some embodiments, the rotary drive mechanism further includes a first tension wheel, a second tension wheel, and a third tension wheel. The first and second tension wheels are mounted on an upper turntable, with the first tension wheel corresponding to a first chain and the second tension wheel corresponding to a second chain. The third tension wheel is mounted on a lower turntable and corresponds to a third chain.

[0016] By adopting the above technical solution and setting a tensioning wheel, the tension of the chain can be adjusted according to the assembly or operation conditions, which helps to reduce the assembly difficulty.

[0017] In some embodiments, the welding mechanism further includes an opening cylinder and an upper cross plate for driving the upper clamp to open. The opening cylinder and the upper cross plate are disposed on the top of the upper turntable. The opening cylinder is located at the input end of the lower cross plate. The opening cylinder presses down to drive the upper clamp to open and clamp the cup foot. The upper cross plate is located at the other end of the lower cross plate, and at least part of the upper cross plate overlaps with the lower cross plate in the vertical direction. The bottom structure of the upper cross plate is high at both ends and low in the middle. The upper cross plate drives the upper clamp to open and release the cup foot.

[0018] By adopting the above technical solution, the upper bridge plate is set at the output end of the lower bridge plate, and the upper bridge plate partially overlaps with the lower bridge plate. This ensures that after welding is completed, the upper clamp opens and loosens the cup feet before unloading, avoiding leaving the welded stem cup on the upper clamp and affecting the subsequent product removal operation.

[0019] In some embodiments, the lower support includes a lower bearing seat mounted on a lower turntable, a lower rotating bushing rotatably engaged with the lower bearing seat, and a lower push rod passing through the lower rotating bushing. A second driven wheel is sleeved on the outer surface of the lower rotating bushing. The lower push rod can slide axially relative to the lower rotating bushing. A first reset member is provided between the bottom of the lower push rod and the bottom of the lower rotating bushing. A cup holder is provided at the top of the lower push rod.

[0020] Using the above technical solution, the cup holder is used to support the opening of the cup body. When the bottom of the lower push rod contacts the lower bridge plate, the cup holder is slowly lifted so that the bottom of the cup body contacts the cup foot, and then is heated and welded together. After the bottom of the lower push rod separates from the lower bridge plate, the cup holder is reset under the action of the first reset component to prepare to support the new cup body.

[0021] In some embodiments, the upper clamping seat includes an upper bearing seat mounted on an upper turntable, an upper rotating bushing rotatably engaged with the upper bearing seat, an upper push rod passing through the upper rotating bushing, and a claw seat connected to the bottom of the upper rotating bushing. A first driven wheel is sleeved on the outer surface of the upper rotating bushing. The upper push rod can slide axially relative to the upper rotating bushing. A second reset member is provided at the end of the lower push rod and the upper rotating bushing away from the claw seat. A clamping claw is hinged on the claw seat, and one end of the clamping claw extending into the claw seat is hinged to the upper push rod.

[0022] Using the above technical solution, when the upper push rod is pressed down, it will cause the gripper to open. When the external force driving the upper push rod to press down is removed, under the action of the second reset member, the upper push rod resets and drives the gripper to close, so as to realize the upper clamping seat clamping or releasing the cup foot.

[0023] In some embodiments, the output end of the turntable power component is connected to a worm gear, and a worm wheel that meshes with the worm gear is provided at the bottom of the lower turntable.

[0024] In some embodiments, the welding mechanism also includes a worm gear jack for adjusting the height of the lower bridge plate.

[0025] By adopting the above technical solution, the height of the lower bridge plate can be adjusted according to the height of the cup body by setting up a worm gear lift, so that the equipment can be used for welding stemmed cups of different heights, thus improving the versatility of the equipment.

[0036] Please see Figures 1 to 6 This invention provides a preferred embodiment of a fully automatic goblet welding machine 100, comprising a frame 10 and a welding mechanism 20 mounted on the frame 10. The frame 10 includes a base 11, a lower turntable 12, and an upper turntable 13 arranged sequentially from bottom to top. The lower turntable 12 and the upper turntable 13 are rotatably connected to the base 11. The base 11 is provided with a turntable power component 14 for driving the lower turntable 12 and the upper turntable 13 to rotate synchronously and intermittently. The welding mechanism 20 includes several lower support seats 21, several upper clamp seats 22, several torches (not shown), and a lower bridge. The lower support plate 23 and the upper clamping plates 22 are rotatably mounted on the lower turntable 12 at intervals along its circumference. The lower support plate 21 and the upper clamping plates 22 are rotatably mounted on the upper turntable 13 at intervals along its circumference. The lower bridge plate 23 is located at the bottom of the lower turntable 12 and extends along its rotation path. The top structure of the lower bridge plate 23 is high in the middle and low at both ends. The torches are arranged at intervals along the circumference of the lower turntable 12 on its sides, and each torch is located above the lower bridge plate 23. The fully automatic goblet welding machine 100 of this application features a simple and compact structure, high safety performance, and low component wear.

[0037] like Figure 4 As shown, the frame 10 also includes a central shaft 15 and a connecting flange 16. One end of the central shaft 15 is fixed to the base 11, and the other end is sequentially connected to the lower turntable 12 and the upper turntable 13. The two ends of the connecting flange 16 are respectively connected to the lower turntable 12 and the upper turntable 13. The lower turntable 12, the upper turntable, and the connecting flange 16 all rotate around the central shaft 15. The lower turntable 12 and the upper turntable 13 are connected by the connecting flange 16, which ensures that the lower turntable 12 and the upper turntable 13 rotate synchronously. By setting the central shaft 15, the upper turntable 13 and the lower turntable 12 are connected to the central shaft 15 through bearings, which makes the rotation of the upper turntable 13, the lower turntable 12, and the connecting flange 16 more stable.

[0038] like Figures 1 to 3As shown, the welding mechanism 20 also includes an opening cylinder 25 and an upper cross plate 26 for driving the upper clamp 22 to open. The opening cylinder 25 and the upper cross plate 26 are disposed on the top of the upper turntable 13. The opening cylinder 25 is located at the input end of the lower cross plate 23. The opening cylinder 25 presses down to drive the upper clamp 22 to open and clamp the cup foot. The upper cross plate 26 is located at the other end of the lower cross plate 23, and at least part of the upper cross plate 26 overlaps with the lower cross plate 23 in the vertical direction. The bottom structure of the upper cross plate 26 is high at both ends and low in the middle. The upper cross plate 26 drives the upper clamp 22 to open and release the cup foot. The upper bridge plate 26 is set at the output end of the lower bridge plate 23, and the upper bridge plate 26 partially overlaps with the lower bridge plate 23. This ensures that after welding is completed, the upper clamp 22 opens and loosens the cup feet before unloading, avoiding leaving the welded stem cup on the upper clamp 22, which would affect the subsequent product removal operation.

[0039] like Figure 5 As shown, specifically, the lower support 21 includes a lower bearing seat 211 mounted on the lower turntable 12, a lower rotating bushing 212 rotatably engaged with the lower bearing seat 211, and a lower push rod 213 passing through the lower rotating bushing 212. The second driven wheel 37 is sleeved on the outer surface of the lower rotating bushing 212. The lower push rod 213 can slide axially relative to the lower rotating bushing 212. A first reset member 214 is provided between the bottom of the lower push rod 213 and the bottom of the lower rotating bushing 212. A cup holder 215 is provided on the top of the lower push rod 213. The cup holder 215 is used to support the opening of the cup body. When the bottom of the lower push rod 213 contacts the lower cross plate 23, the cup holder 215 is slowly pushed up so that the bottom of the cup body contacts the cup foot, and then they are heated and welded together. After the bottom of the lower push rod 213 separates from the lower cross plate 23, the cup holder 215 is reset under the action of the first reset member 214 to prepare to support a new cup body.

[0040] like Figure 6As shown, the upper clamping seat 22 includes an upper bearing seat 221 mounted on the upper turntable 13, an upper rotating bushing 222 rotatably engaged with the upper bearing seat 221, an upper push rod 223 passing through the upper rotating bushing 222, and a claw seat 224 connected to the bottom of the upper rotating bushing 222. The first driven wheel 36 is sleeved on the outer surface of the upper rotating bushing 222. The upper push rod 223 can slide axially relative to the upper rotating bushing 222. The lower push rod 213 and the end of the upper rotating bushing 222 away from the claw seat 224 are provided with a second reset member 225. A claw 226 is hinged on the claw seat 224. The end of the claw 226 extending into the claw seat 224 is hinged to the upper push rod 223. When the upper push rod 223 is pressed down, it causes the gripper 226 to open. When the external force driving the upper push rod 223 to press down is removed, under the action of the second reset member 225, the upper push rod 223 resets and drives the gripper 226 to close, so that the upper clamping seat 22 can clamp or release the cup foot. In this example, each upper clamping seat 22 is provided with three grippers 226. In other embodiments, the number of grippers 226 can be increased or decreased as needed, as long as it can clamp the cup foot or cup body and drive it to rotate.

[0041] Since the stem and body of the stemmed glass are respectively mounted on the upper clamp 22 and the lower support 21, and in order to ensure uniform heating at the weld joint, the stem and body need to rotate during the welding process. This requires the upper clamp 22 and the lower support 21 to rotate synchronously. Otherwise, spiral patterns may easily appear at the weld joint between the stem and the body, and in severe cases, breakage may occur, affecting the quality of the welded product. Therefore, the fully automatic stemmed glass welding machine 100 of this application also includes a rotary drive mechanism 30 for driving the rotation of each lower support 21 and each upper clamp 22.

[0042] like Figure 2 and Figure 4As shown, the rotary drive mechanism 30 includes a rotary power component 31, a driving wheel 32, a first driven wheel 33, and a second driven wheel 34. The rotary power component 31 is mounted on the central shaft 15. The driving wheel 32 is drivenly connected to the output end of the rotary power component 31, and the driving wheel 32 is coaxial with the central shaft 15. The first driven wheel 33 is mounted on the upper turntable 13, and the second driven wheel 34 is mounted on the lower turntable 12. The first driven wheel 33 is drivenly connected to the driving wheel 32. The first driven wheel 33 and the second driven wheel 34 are connected by a synchronous shaft 35. Each upper clamp 22 is provided with a first driven wheel 36 that is drivenly connected to the first driven wheel 33, and each lower support 21 is provided with a second driven wheel 37 that is drivenly connected to the second driven wheel 34. This configuration allows a single rotating power component 31, in conjunction with a synchronous shaft 35, to drive multiple lower support seats 21 and multiple upper clamp seats 22 to rotate synchronously. This saves on the number of power components and reduces costs. Furthermore, it ensures that the lower support seats 21 and upper clamp seats 22 can rotate synchronously, ensuring a good welding effect. In addition, by placing the drive wheel 32 on the axis of the central shaft 15, it ensures that the center distance between the drive wheel 32 and the first driven wheel 33 and the second driven wheel 34 remains constant during the rotation of the upper turntable 13 and the lower turntable 12, ensuring smooth power transmission and improving transmission accuracy.

[0043] To make the rotational movement control of the upper clamp 22 and the lower support 21 more precise, the rotational power component 31 is preferably a servo motor.

[0044] like Figure 2 As shown, in this embodiment, a transition wheel 38 is also provided on the synchronous shaft 35. The transition wheel 38 is connected to the driving wheel 32 via a first chain drive, the first driven wheel 33 is connected to each of the first driven wheels 36 via a second chain drive, and the second driven wheel 34 is connected to the second driven wheel 37 via a third chain drive. Chain drive can ensure transmission accuracy and avoid slippage during transmission. Moreover, chain drive has a certain degree of flexibility, which can improve the fault tolerance rate, reduce assembly requirements, and help reduce costs.

[0045] Furthermore, the rotary drive mechanism 30 also includes a first tensioning wheel (not shown), a second tensioning wheel (not shown), and a third tensioning wheel (not shown). The first and second tensioning wheels are mounted on the upper turntable 13, with the first tensioning wheel corresponding to the first chain and the second tensioning wheel corresponding to the second chain. The third tensioning wheel is mounted on the lower turntable 12, and corresponds to the third chain. By setting the tensioning wheels, the tension of the chain can be adjusted according to assembly or operation conditions, which helps to reduce assembly difficulty.

[0046] Preferably, the sprockets in this embodiment are all double-tower sprockets because double-tower sprockets have the following characteristics: 1. High transmission stability: Double-tower sprockets use double chain drive, which has high transmission stability, is not prone to tooth skipping, and transmits power smoothly; 2. High transmission power: Since double-tower sprockets can transmit two chains at the same time, the transmitted power is large, making them suitable for high-power transmission; 3. Long service life: Double-tower sprockets have advantages such as simple structure, long service life, and low maintenance cost.

[0047] In other embodiments, the rotational power element 31 may also provide a gear set to drive the lower support 21 and the upper clamp 22 to rotate.

[0048] In this embodiment, the number of lower support base 21 and upper clamping base 22 is thirty-six. In other embodiments, the number of lower support base 21 and upper clamping base 22 can be increased or decreased according to needs, and is not limited to the specific number shown in the figure.

[0049] like Figure 2 As shown, several musket mounting brackets 24 for mounting muskets are provided on the side of the lower turntable 12. Each musket mounting bracket 24 is spaced apart along the circumference of the lower turntable 12. One or more muskets can be mounted on each musket mounting bracket 24 as needed. Multiple gas bags for supplying gas to the muskets are provided at the bottom of the musket mounting bracket 24.

[0050] like Figure 1 and Figure 3 As shown, the welding mechanism 20 also includes a worm gear jack 27 for adjusting the height of the lower bridge plate 23. By setting the worm gear jack 27, the height of the lower bridge plate 23 can be adjusted according to the height of the cup body, making the equipment suitable for welding stemmed cups of different heights and improving the versatility of the equipment.

[0051] Preferably, in this embodiment, the turntable power component 14 is a servo motor. Using a servo motor as the turntable power component 14 allows for more precise control of the rotation of the lower turntable 12 and the upper turntable 13, resulting in more accurate control of the rotation speed and pause duration. Furthermore, a worm gear is connected to the output end of the turntable power component 14, and a worm wheel meshing with the worm gear is provided at the bottom of the lower turntable 12.

[0052] The fully automatic stemmed glass welding machine 100 of this application sets the lower turntable 12 and the upper turntable 13 to rotate intermittently. That is, the lower turntable 12 and the upper turntable 13 will pause for a certain period of time after rotating at a preset angle, but the lower support base 21 and the upper clamping base 22 will always maintain synchronous rotation. The advantage of this design is that the position and duration of the pause of the lower turntable 12 and the upper turntable 13 can be set according to the position of the torch and the rotation speed of the lower support base 21 and the upper clamping base 22. In this way, while the torch is stationary, the lower support base 21 and the upper clamping base 22 drive the stem and the body of the cup to rotate, so that the welding joint between the stem and the body of the cup is heated evenly, ensuring the welding quality. Moreover, since the torch is always stationary during operation, the risk of the pipe connected to the torch falling off or being damaged can be reduced, thereby extending the service life of the parts and improving safety.

[0053] Finally, it should be noted that the above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
