Description

Technical Field

[0001] The invention relates to the technical field of welding equipment, in particular to special infrared welding equipment. Background Art

[0002] In the field of industrial automation and precision manufacturing, infrared welding technology is widely used in many industries such as automobile manufacturing, electronic devices, aerospace, etc. due to its advantages such as non-contact heating, high efficiency and energy saving, and high welding strength.

[0003] During the infrared welding process, uniform heating of the workpiece is the key to ensuring welding quality. Traditional welding equipment often uses a fixed heating method, which is difficult to adapt to the welding needs of complex-shaped workpieces and easily leads to problems such as uneven heating and insufficient welding strength. The heating wires of the existing equipment heating modules have gaps, resulting in uneven heating of the product and the possibility of air leakage in the poorly heated parts. At the same time, during the welding process, the firm clamping of the workpiece is also an important factor in ensuring the welding effect. If the clamping is unstable, it is easy to cause the workpiece to shift and deform, thereby affecting the welding quality. When handling large or heavy workpieces, traditional infrared welding equipment often relies on simple mechanical fixtures or manual operations to fix the workpiece. However, these methods have many shortcomings. The upper clamping product mechanism is heavy. If the production line suddenly runs out of gas, the entire clamping product mechanism will fall quickly, and there is a risk of collision with the machine and injury to people, thereby increasing the risk of workpiece falling.

[0004] Therefore, how to achieve uniform heating, ensure product stability during welding, and prevent the risk of falling during welding have become important considerations in the design of infrared welding equipment. Summary of the invention

[0005] The object of the present invention is to provide a special infrared welding device to solve the problems raised in the above background technology.

[0006] In order to solve the above technical problems, the present invention provides the following technical solutions:

[0007] The special infrared welding equipment includes a frame, a transmission unit, a clamping unit, an anti-falling unit and a sliding unit, the frame is placed on a horizontal basis, the transmission unit is fixedly mounted on the upper surface of the frame away from the horizontal basis, the transmission unit is rotatably connected to the clamping unit, the clamping unit is slidably connected to the frame, the clamping unit has the function of clamping and heating the product, the anti-falling unit is fixedly connected to the transmission unit, the anti-falling unit is fixedly mounted on the upper surface of the frame away from the horizontal basis, the anti-falling unit has the function of locking the upper clamping unit, and the sliding unit is slidably mounted on the upper surface of the frame close to the horizontal basis.

[0008] The frame is used to install and fix the transmission unit, clamping unit, anti-fall unit and sliding unit. The transmission unit is used to provide a power source for the rotation of the product. The clamping unit is used to clamp the product while rotating and heating the product. The anti-fall unit is used to prevent the upper clamping unit from falling quickly due to being too heavy and causing damage. The sliding unit is used to weld two products. When the product is placed in the sliding unit, the transmission unit is started by the controller to drive the clamping unit to clamp the product and rotate it at the same time, so that the product is heated evenly and avoids air leakage caused by uneven heating, thereby improving the welding firmness and airtightness. The upper clamping unit is locked by the anti-fall unit to prevent the entire upper clamping unit from falling quickly when the production line is suddenly cut off, resulting in the risk of collision with the machine and injury to people.

[0009] Furthermore, the transmission unit includes a motor, a spline shaft, a spline sleeve, a synchronous wheel, a bearing, a pressure plate, a synchronous belt and a support plate. The fixed end of the motor is fixedly installed on the upper surface of the frame away from the horizontal foundation. The output end of the motor passes through the frame and is fixedly connected to the spline shaft. The spline shaft is slidingly connected to the synchronous wheel through the spline sleeve. The spline sleeve is rotatably connected to the synchronous wheel. The spline sleeve is rotatably connected to the bearing. The bearing is fixedly connected to the pressure plate at one end close to the horizontal foundation. The bearing is fixedly connected to the support plate. The synchronous wheel is rotatably connected to the clamping unit through a synchronous belt.

[0010] When the staff puts the product into the welding place, the controller controls the motor to start and drive the spline shaft to rotate, thereby driving the support plate up and down under the action of the spline sleeve, and driving the synchronous wheel to rotate. Through the transmission of the synchronous belt, the clamping unit rotates and moves back and forth up and down with the support plate.

[0011] Furthermore, the clamping unit includes a driven wheel, a main cylinder, a turntable, a clamping block and a heating block. The driven wheel is rotatably connected to the synchronous wheel through a synchronous belt. The main cylinder is fixedly installed on the upper surface of the frame at one end away from the horizontal base. The driven wheel is fixedly connected to the turntable, the clamping block is fixedly connected to the turntable, and the clamping block is fixedly connected to the heating block.

[0012] The driven wheel is driven by the synchronous belt to rotate synchronously, thereby driving the turntable to rotate together. The rotation of the turntable drives the clamping block and the heating block to rotate while reciprocating up and down synchronously with the support plate, thereby clamping the product. At this time, the controller passes current into the heating block, so that the heating block generates heat to evenly heat the rotating product, avoiding the problem of uneven heating at the gap of the heating wire, improving the uniformity of the welding weld, and ensuring the stability of the product welding quality.

[0013] Furthermore, the anti-fall unit includes a cylinder, an installation box, a return spring, a lock tongue and a lock tongue rod. The cylinder is fixedly installed on the upper surface of the frame away from the horizontal foundation, and the cylinder is conductively connected to the inside of the installation box. The installation box is fixedly installed on the upper surface of the frame away from the horizontal foundation. A return spring groove is provided inside the installation box. One end of the return spring is fixedly installed in the return spring groove in the installation box, and the other end is fixedly connected to the lock tongue. The lock tongue is slidably installed in the installation box parallel to the horizontal axis. The lock tongue rod is slidably connected to the installation box parallel to the vertical axis, and the lock tongue rod is fixedly connected to the support plate at one end close to the horizontal foundation.

[0014] If the production line is suddenly cut off from air, the cylinder stops supplying air. At this time, the reset spring pushes the lock tongue out under the action of the restoring force, so that the lock tongue is engaged with the lock tongue rod, so that the upper clamping unit is fixed in the original position and no longer reciprocates up and down with the synchronous wheel, thereby avoiding the clamping unit on the upper part that is heavy and falls rapidly, causing collisions with the machine and injuries to people. When the production line resumes air supply, the reset spring is compressed and drives the lock tongue to separate from the lock tongue rod, so that the upper clamping unit resumes work.

[0015] Furthermore, the sliding unit includes a vertical plate, a small cylinder, a placement plate and a right-angle plate, the right-angle plate is fixedly mounted on the upper surface of the frame close to the horizontal foundation, the small cylinder is fixedly mounted on the end of the right-angle plate away from the horizontal foundation, the vertical plate is fixedly mounted on the upper surface of the frame close to the horizontal foundation, and the placement plate is slidably mounted on the end of the vertical plate frame away from the horizontal foundation.

[0016] When the product is heated, the controller controls the small cylinder to contract and drive the placement plate to slide backward on the vertical plate. At the same time, the controller controls the main cylinder above to extend and push the upper clamping unit to drive the product to move downward, so that the two heated products are welded together, completing the product welding process.

[0017] Furthermore, an air intake adapter plate is provided at one end of the turntable close to the driven wheel, and a plurality of air intake ports are provided on the air intake adapter plate. Three sealing rings are added inside the air intake plate, and a plurality of air outlet ports are provided inside the turntable.

[0018] The gas is introduced through the air inlet on the air inlet adapter plate and discharged from the air outlet of the turntable, so that the product is clamped by air pressure while it rotates, thereby improving the uniform heating of the product while ensuring air tightness. In addition, three sealing rings are added inside the air inlet adapter plate to ensure that the two groups of air paths can provide air pressure at the same time during rotation without affecting each other.

[0019] Furthermore, the placement plate can withstand a high temperature of 500 degrees.

[0020] In order to enhance the durability of the equipment, it is possible to prevent equipment working in a high temperature environment for a long time from being easily affected by thermal stress, which may lead to problems such as component aging and failure. At the same time, it can reduce safety risks such as material deformation, melting or fire caused by high temperature.

[0021] Furthermore, the heating block is electrically connected to an external controller.

[0022] In order to realize the automatic and refined control of the product welding process, during the product heating process, the product can always maintain the optimal heating temperature through precise temperature control heating, thereby improving the welding quality of the product.

[0023] Compared with the prior art, the beneficial effect achieved by the present invention is that the present invention realizes the synchronous movement of the upper and lower clamping units through the cooperation of the transmission unit motor, synchronous belt, spline shaft and synchronous wheel, thereby ensuring uniform heating of the product, uniform welding seam, and stable welding quality and airtightness of the product.

[0024] The present invention introduces gas through the air inlet of the air inlet adapter plate below the turntable in the clamping unit, and the gas is discharged from the air outlet of the turntable, so that the product is clamped by air pressure while rotating, thereby improving uniform heating of the product while ensuring air tightness;

[0025] The present invention uses a reset spring in the anti-falling unit. When the production line is suddenly cut off, the reset spring pushes the lock tongue out under the action of the restoring force, so that the lock tongue is engaged with the lock tongue rod, thereby fixing the upper clamping unit, thereby preventing the clamping unit for clamping the product on the upper part from being heavy and falling rapidly, causing collision with the machine and injuring people.

DETAILED DESCRIPTION

[0037] 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.

[0038] The present invention provides a technical solution:

[0039] like Figure 1 As shown, a special infrared welding equipment includes a frame 1, a transmission unit 2, a clamping unit 3, an anti-falling unit 4 and a sliding unit 5. The frame 1 is placed on a horizontal basis, the transmission unit 2 is fixedly installed on the upper surface of the frame 1 away from the horizontal basis, the transmission unit 2 is rotatably connected to the clamping unit 3, the clamping unit 3 is slidably connected to the frame 1, the clamping unit 3 has the function of clamping and heating the product, the anti-falling unit 4 is fixedly connected to the transmission unit 2, the anti-falling unit 4 is fixedly installed on the upper surface of the frame 1 away from the horizontal basis, the anti-falling unit 4 has the function of locking the upper clamping unit 3, and the sliding unit 5 is slidably installed on the upper surface of the frame 1 close to the horizontal basis.

[0040] The frame 1 is used to install and fix the transmission unit 2, the clamping unit 3, the anti-falling unit 4 and the sliding unit 5. The transmission unit 2 is used to provide a power source for the rotation of the product. The clamping unit 3 is used to clamp the product while rotating and heating the product. The anti-falling unit 4 is used to prevent the upper clamping unit 3 from falling quickly due to being too heavy and causing damage. The sliding unit 5 is used for welding two products. When the product is placed in the sliding unit 5, the transmission unit 2 is started by the controller to drive the clamping unit 3 to clamp the product and rotate it at the same time, so that the product is heated evenly and leakage caused by uneven heating is avoided, thereby improving the welding firmness and air tightness. The upper clamping unit 3 is locked by the anti-falling unit 4 to prevent the entire upper clamping unit 3 from falling quickly when the production line is suddenly cut off, resulting in the risk of colliding with the machine and injuring people.

[0041] like Figure 2 , 9 As shown, the transmission unit 2 includes a motor 21, a spline shaft 22, a spline sleeve 23, a synchronous wheel 24, a bearing 25, a pressure plate 26, a synchronous belt 27 and a support plate 28. The fixed end of the motor 21 is fixedly installed on the upper surface of the frame 1 away from the horizontal foundation. The output end of the motor 21 passes through the frame 1 and is fixedly connected to the spline shaft 22. The spline shaft 22 is slidingly connected to the synchronous wheel 24 through the spline sleeve 23. The spline sleeve 23 is rotatably connected to the synchronous wheel 24. The spline sleeve 23 is rotatably connected to the bearing 25. The end of the bearing 25 close to the horizontal foundation is fixedly connected to the pressure plate 26. The bearing 25 is fixedly connected to the support plate 28. The synchronous wheel 24 is rotatably connected to the clamping unit 3 through the synchronous belt 27.

[0042] When the staff puts the product into the welding place, the controller controls the motor 21 to start and drive the spline shaft 22 to rotate, thereby driving the support plate 28 to move up and down under the action of the spline sleeve 23, and driving the synchronous wheel 24 to rotate. Through the transmission of the synchronous belt 27, the clamping unit 3 rotates and moves back and forth up and down with the support plate 28.

[0043] like Figure 3 , 6 As shown in Figure 8, the clamping unit 3 includes a driven wheel 31, a main cylinder 32, a turntable 33, a clamping block 34 and a heating block 35. The driven wheel 31 is rotatably connected to the synchronous wheel 24 through a synchronous belt 27. The main cylinder 32 is fixedly installed on the upper surface of the frame 1 at one end away from the horizontal foundation. The driven wheel 31 is fixedly connected to the turntable 33, the clamping block 34 is fixedly connected to the turntable 33, and the clamping block 34 is fixedly connected to the heating block 35.

[0044] Under the transmission action of the synchronous belt 27, the driven wheel 31 is driven to rotate synchronously, thereby driving the turntable 33 to rotate together. The rotation of the turntable 33 drives the clamping block 34 and the heating block 35 to rotate while reciprocating up and down synchronously with the support plate 28, thereby clamping the product. At this time, the controller passes current into the heating block 35, so that the heating block 35 generates heat to evenly heat the rotating product, avoiding the problem of uneven heating at the gap of the heating wire, improving the uniformity of the welding weld, and ensuring the stability of the product welding quality.

[0045] like Figure 7 As shown, the anti-fall unit 4 includes a cylinder 41, an installation box 42, a return spring 43, a lock tongue 44 and a lock tongue rod 45. The cylinder 41 is fixedly installed on the upper surface of the end of the frame 1 away from the horizontal foundation. The cylinder 41 is conductively connected to the inside of the installation box 42. The installation box 42 is fixedly installed on the upper surface of the end of the frame 1 away from the horizontal foundation. A return spring groove is provided inside the installation box 42. One end of the return spring 43 is fixedly installed in the return spring groove in the installation box 42, and the other end is fixedly connected to the lock tongue 44. The lock tongue 44 is slidably installed in the installation box 42 parallel to the horizontal axis. The lock tongue rod 45 is slidably connected to the installation box 42 parallel to the vertical axis, and the lock tongue rod 45 is fixedly connected to the support plate 28 at one end close to the horizontal foundation.

[0046] If the production line is suddenly cut off from air, the cylinder 41 stops supplying air. At this time, the reset spring 43 pushes the locking tongue 44 out under the action of the restoring force, so that the locking tongue 44 is engaged with the locking tongue rod 45, so that the upper clamping unit 3 is fixed in the original position and no longer reciprocates up and down with the synchronous wheel 24, thereby avoiding the upper clamping unit 3 that is heavy and clamps the product, and falls rapidly, causing collisions with the machine and injuring people. When the production line resumes air supply, the reset spring 43 is compressed and drives the locking tongue 44 to separate from the locking tongue rod 45, so that the upper clamping unit 3 resumes work.

[0047] like Figure 2 As shown, the sliding unit 5 includes a vertical plate 51, a small cylinder 52, a placement plate 53 and a right-angle plate 54. The right-angle plate 54 is fixedly mounted on the upper surface of the frame 1 at one end close to the horizontal foundation, the small cylinder 52 is fixedly mounted on the right-angle plate 54 at one end away from the horizontal foundation, the vertical plate 51 is fixedly mounted on the upper surface of the frame 1 at one end close to the horizontal foundation, and the placement plate 53 is slidably mounted on the vertical plate 51 at one end of the frame 1 away from the horizontal foundation.

[0048] When the product is heated, the controller controls the small cylinder 52 to contract and drive the placement plate 53 to slide backward on the vertical plate 51. At the same time, the controller controls the main cylinder 32 above to extend and push the upper clamping unit 3 to drive the product to move downward, so that the two heated products are welded together, completing the product welding process.

[0049] like Figure 8As shown, an air intake adapter plate is provided at one end of the turntable 33 close to the driven wheel 31 , and a plurality of air intake ports are provided on the air intake adapter plate. Three sealing rings are added inside the air intake plate, and a plurality of air outlet ports are provided inside the turntable 33 .

[0050] The gas is introduced through the air inlet on the air inlet adapter plate, and the gas is discharged from the air outlet of the turntable 33, so that the product is clamped by air pressure while it is rotating, thereby improving the uniform heating of the product while ensuring the air tightness. In addition, three sealing rings are added inside the air inlet adapter plate to ensure that the two groups of air paths can provide air pressure at the same time when rotating without affecting each other.

[0051] like Figure 2 As shown, the placement plate 53 can withstand a high temperature of 500 degrees.

[0052] In order to enhance the durability of the equipment, it is possible to prevent equipment working in a high temperature environment for a long time from being easily affected by thermal stress, which may lead to problems such as component aging and failure. At the same time, it can reduce safety risks such as material deformation, melting or fire caused by high temperature.

[0053] like Figure 3 As shown, the heating block 35 is electrically connected to the external controller.

[0054] In order to realize the automatic and refined control of the product welding process, during the product heating process, the product can always maintain the optimal heating temperature through precise temperature control heating, thereby improving the welding quality of the product.

[0055] Working principle of the present invention:

[0056] When the staff puts the product into the welding place, the controller controls the motor 21 to start and drive the spline shaft 22 to rotate, so that the support plate 28 is driven up and down by the action of the spline sleeve 23, and the synchronous wheel 24 is driven to rotate. Through the transmission of the synchronous belt 27, the clamping unit 3 is rotated and moves up and down with the support plate 28. Under the transmission action of the synchronous belt 27, the driven wheel 31 is driven to rotate synchronously, thereby driving the turntable 33 to rotate together. The rotation of the turntable 33 drives the clamping block 34 and the heating block 35 to rotate while synchronously reciprocating up and down with the support plate 28, thereby clamping the product. At this time, the controller passes current into the heating block 35, so that the heating block 35 generates heat to evenly heat the rotating product, avoiding the problem of uneven heating at the gap of the heating wire, improving the uniformity of the welding weld, and ensuring the stability of the product welding quality. When the product is heated, the controller controls the small cylinder 52 to contract and drive the placement plate 53 to slide backward on the vertical plate 51. At the same time, the controller controls the main cylinder 32 above to extend and push the upper clamping unit 3 to drive the product to move downward, so that the two heated products are welded together to complete the product welding process. If the production line is suddenly cut off from gas, the cylinder 41 stops supplying gas. At this time, the reset spring 43 pushes the lock tongue 44 out under the action of the restoring force, so that the lock tongue 44 is engaged with the lock tongue rod 45, so that the upper clamping unit 3 is fixed in the original position and no longer reciprocates up and down with the synchronous wheel 24, thereby avoiding the upper clamping unit 3 that clamps the product is heavy and falls rapidly, causing collisions with the machine and injuries to people. When the production line resumes gas supply, the reset spring 43 is compressed and drives the lock tongue 44 to separate from the lock tongue rod 45, so that the upper clamping unit 3 resumes work.
