Description

Technical Field

[0001] The present invention relates to the technical field of power adapter welding devices, and specifically to a power adapter production welding device. Background Art

[0002] A power adapter is a power supply conversion device for small portable electronic devices and electronic appliances. It generally consists of components such as a housing, a transformer, an inductor, a capacitor, a control IC, and a PCB board. Its working principle is to convert AC input into DC output; it can be divided into wall-mounted and desktop types according to the connection method, and is widely used in devices such as security cameras, set-top boxes, routers, light strips, and massagers.

[0003] In order to protect the internal electronic components of the power adapter, a housing is generally installed on the outer peripheral side of many electronic components of the power adapter. The housing is generally divided into plastic, metal, and rubber housings, etc. The housing is generally divided into two parts. During the production process of the power adapter, a welding device is generally required to perform hot melt welding and assembly on the two halves of the housing of the power adapter. Usually, the welding head heats the connection part of the housing, and the welding efficiency is slow by moving the welding head along the gap. Moreover, during the process of heating the connection part of the housing, due to the characteristic of the rubber material being softened by heat, it is easy to cause the part of the housing near the housing gap to be softened and deformed, and as the part of the housing is softened, it is easy to cause a certain offset between the two parts of the housing. After the housing is welded, there is likely to be excess material outside the gap, which will result in a large number of power adapters that need external precision repair after the housing is welded, and it cannot well meet the welding requirements of the power adapter housing. Summary of the Invention

[0004] The purpose of the present invention is to provide a power adapter production welding device to solve the problems raised in the above background art.

[0005] To achieve the above purpose, the present invention provides the following technical solution: A power adapter production welding device includes a base and a power adapter. The housing of the power adapter is divided into an upper shell and a lower shell. A placement groove is opened at the center position of the top of the base, and the lower shell passes through the placement groove of the base. A number of mounting holes are oppositely opened inside the base;

[0006] It further includes:

[0007] The first hydraulic rod is located above the base, and the first hydraulic rod is fixedly connected to the base through a bracket. The output end of the first hydraulic rod is fixedly provided with a housing. The upper housing is inserted into the housing, and the upper housing is in interference fit with the inner wall of the housing. A plurality of sliding grooves are formed in the inner wall of the housing corresponding to the connection between the upper housing and the lower housing. A heating plate is slidably inserted into the sliding grooves. A plurality of second hydraulic rods are fixedly inserted through the outer peripheral wall of the housing corresponding to the position of the heating plate by bolts, and the output end of each second hydraulic rod is inserted into the corresponding sliding groove. Cooling components are provided on both sides of the heating plate;

[0008] A plurality of heat preservation components. An adjusting component is provided on the outer peripheral side of the upper housing. The heat preservation components are installed between the adjusting component and the corresponding cooling components and the corresponding heating plates.

[0009] Preferably, the housing is a heat-insulating housing, and a heat-conducting non-stick coating is attached to the outer wall of the heating plate.

[0010] By adopting the above technical solution, the heat-insulating housing provided makes the heat of the heating plate not conduct to the outside, and the setting of the heat-conducting non-stick coating makes the heating plate not stick to the softened parts of the upper housing and the lower housing after contacting and heating them.

[0011] Preferably, the cooling component includes a plurality of heat-insulating pipes arranged in a rectangular tube shape. The plurality of heat-insulating pipes are oppositely arranged on both sides of the plurality of heating plates, and the open end of each heat-insulating pipe extends into the housing and is in the same plane as the corresponding inner wall of the housing. One side of the heat-insulating pipe close to the corresponding heating plate is in contact with the corresponding heating plate. A heat-conducting block is slidably installed in the opening of the heat-insulating pipe, and a sealing ring is installed on the outer peripheral wall of the heat-conducting block.

[0012] By adopting the above technical solution, the mutual cooperation between the heat-insulating pipe and the inner wall of the sliding groove restricts and positions the movement of the heating plate from the four sides of the heating plate, so that the heating plate moves along a certain track.

The heat-insulating block is fixedly installed at one end of the corresponding heating plate located in the corresponding sliding groove, and the heat-insulating block is in contact with the inner wall of the corresponding sliding groove. The heat-insulating block is threadedly connected to the output end of the corresponding second hydraulic rod. A first heat-conducting plate is fixedly inserted through one end of the heat-insulating pipe close to the corresponding heating plate.

[0014] By adopting the above technical solution, the heat conduction between the heating plate and the second hydraulic rod is isolated by the heat-insulating pipe, avoiding the high temperature on the heating plate from being conducted to the second hydraulic rod and affecting the use of the second hydraulic rod.

One end of the first heat-conducting plate is in contact with the corresponding heating plate, and a number of second heat-conducting plates are fixedly installed at the other end of the first heat-conducting plate. A large number of honeycomb-shaped holes are formed in the second heat-conducting plates.

[0016] By adopting the above technical solution, the setting of the first heat-conducting plate enables heat conduction to occur between the heating plate and the heat storage solution in the heat-insulating tube when the heating plate retracts into the sliding groove. The honeycomb-shaped holes on the second heat-conducting plates increase the contact area between the second heat-conducting plates and the heat storage solution, and increase the rate at which the heating plate transfers heat into the heat storage solution.

[0017] Preferably, the adjusting assembly includes an airbag. A storage groove in the shape of a rectangular ring is formed in the inner top side of the outer shell. The airbag passes through the storage groove, and the top end of the airbag is fixedly connected to the inner wall of the storage groove.

[0018] By adopting the above technical solution, the inflation and deformation of the airbag simultaneously push the upper shell downward from the four surrounding sides of the top side of the upper shell, and the pushing effect is stable.

[0019] Preferably, a number of piston cylinders are fixedly installed above the sliding groove. A number of first one-way valves are fixedly penetrated through the outer wall of the outer shell at positions corresponding to the piston cylinders, and one end of each first one-way valve located inside the outer shell is communicated and installed with the corresponding piston cylinder. A connecting pipe is provided between the airbag and the corresponding piston cylinder. One end of the connecting pipe is communicated and installed with the airbag, and the other end of the connecting pipe is communicated and installed with the corresponding piston cylinder through a second one-way valve. A number of exhaust thin pipes are communicated and installed at the top end of the airbag, and the top end of each exhaust thin pipe extends to the top side of the outer shell.

[0020] By adopting the above technical solution, through the mutual cooperation of the first one-way valve, the second one-way valve and the connecting pipe, the gas in the piston cylinder flows into the airbag unidirectionally, and the air in the airbag is discharged to the outside through the exhaust thin pipes to form a directional gas path, so that the airbag can automatically return to its original state after expansion, facilitating the use of the device.

[0021] Preferably, a piston plate is installed in the piston cylinder, and the first one-way valve is located above the corresponding piston plate. Air is filled on both sides of the piston plate. A resilient drawstring is fixedly installed at the center position of the bottom end of the piston plate. The bottom end of the resilient drawstring is inserted into the corresponding sliding groove and fixedly connected to the corresponding heat-insulating block. A sealing ring is provided between the resilient drawstring and the barrel wall of the corresponding piston cylinder.

[0022] By adopting the above technical solution, the setting of the resilient drawstring enables the heating plate to automatically pull the piston plate downward during the moving process, and the piston plate is automatically reset by the gas below the piston plate, without the need to set an additional power source, facilitating the use of the device.

[0023] Compared with the prior art, the beneficial effects of the present invention are as follows: The improved welding device softens the bonding surface of the housing by simultaneously heating it with a plurality of heating plates, which has high efficiency. During the heating process, the heat near the housing gap is absorbed by the cooling component to prevent the part near the housing gap from softening. At the same time, when the upper housing and the lower housing are spliced, the heat preservation component prolongs the cooling time of the bonding surface, and the positioning of the upper housing and the lower housing is completed through the adjustment component, the cooling component and the heat preservation component. Meanwhile, the constraint surface formed by the cooling component and the heat preservation component seals the gap between the bonding surfaces, so that it is not easy to generate excess material outside when the upper housing and the lower housing are bonded, reducing the number of power adapters that need external precision repair after the housing welding is completed, and being able to well meet the welding requirements of the power adapter. The device is easy to use, and the specific content is as follows;

[0024] 1. There are heating plates and a housing. When welding the improved power adapter, the bonding surface of the housing is heated and softened simultaneously by a plurality of heating plates, which has high efficiency. During the heating process, the heat near the housing gap is absorbed by the cooling component to prevent the part near the housing gap from softening. After the bonding surfaces of the upper housing and the lower housing are heated and softened, the heating plates retract into the chute and reset.

Specific implementation manner

[0032] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0033] Please refer to Figure 1-2 , the present invention provides a technical solution: a production welding device for a power adapter 2, including a base 1 and a power adapter 2. The outer shell 8 of the power adapter 2 is divided into two parts, an upper shell 21 and a lower shell 22. A placement groove is opened at the center of the top end of the base 1. When welding the upper shell 21 and the lower shell 22, the lower shell 22 passes through the placement groove of the base 1. A number of mounting holes are oppositely opened in the base 1, and the base 1 is fixedly installed on the workbench through bolts and the mounting holes; further included are: a first hydraulic rod 6, the first hydraulic rod 6 is located above the base 1, and the first hydraulic rod 6 is fixedly connected to the base 1 through a bracket 7. The output end of the first hydraulic rod 6 is fixedly installed with an outer shell 8. When welding the upper shell 21 and the lower shell 22, the upper shell 21 passes through the outer shell 8, and the upper shell 21 is in interference fit with the inner wall of the outer shell 8. A number of chutes 9 are opened on the inner wall of the outer shell 8 corresponding to the connection position of the upper shell 21 and the lower shell 22. A heating plate 10 is slidably passed through the chutes 9. A number of second hydraulic rods 11 are fixedly passed through the outer peripheral wall of the outer shell 8 corresponding to the position of the heating plate 10 through bolts, and the output end of each second hydraulic rod 11 is inserted into the corresponding chute 9. The first hydraulic rod 6 and the second hydraulic rod 11 are connected to an external liquid injection device, and the liquid injection device controls the telescoping of the first hydraulic rod 6 and the second hydraulic rod 11. The outer shell 8 is a heat insulation shell, and a heat conducting non-stick coating is attached to the outer wall of the heating plate 10. The heat conducting non-stick coating is similar to the surface coating of a non-stick pan in the prior art. The heat insulation shell provided by the outer shell 8 enables the heat of the heating plate 10 not to be conducted to the outside, and the setting of the heat conducting non-stick coating enables the heating plate 10 not to stick to the softened parts of the upper shell 21 and the lower shell 22 after contacting and heating them.

[0034] According to Figure 2 and Figure 5 As shown, cooling components 3 are provided on both sides of the heating plate 10. The cooling component 3 includes a number of heat-insulating tubes 31 arranged in a rectangular tube shape. The number of heat-insulating tubes 31 are oppositely arranged on both sides of the number of heating plates 10, and the open end of each heat-insulating tube 31 extends into the housing 8 and is in the same plane as the corresponding inner wall of the housing 8. The side of the heat-insulating tube 31 close to the corresponding heating plate 10 is in contact with the corresponding heating plate 10. A heat-conducting block 32 is slidably installed in the opening of the heat-insulating tube 31. A sealing ring 33 for blocking the gap between the outer peripheral wall of the heat-conducting block 32 and the inner wall of the corresponding heat-insulating tube 31 is installed on the outer peripheral wall of the heat-conducting block 32. The sealing ring 33 is a metal ring. The movement of the heating plate 10 is restricted and positioned by the mutual cooperation between the heat-insulating tube 31 and the inner wall of the sliding groove 9 around the heating plate 10.

[0035] According to Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 and Figure 6As shown, there are several heat insulation components 4, and an adjustment component 5 is provided on the outer peripheral side of the upper shell 21. The adjustment component 5 includes an airbag 52. A storage groove 51 in the shape of a rectangular ring is formed in the inner top side of the outer shell 8. The airbag 52 is inserted into the storage groove 51, and the top end of the airbag 52 is fixedly connected to the inner wall of the storage groove 51. The airbag 52 is a soft airbag 52, and the wall of the airbag 52 can be expanded or contracted and deformed. Above the chute 9, several piston cylinders 53 are fixedly installed. At the positions corresponding to the several piston cylinders 53 on the outer wall of the outer shell 8, several first one-way valves 54 are fixedly penetrated. And one end of each first one-way valve 54 located inside the outer shell 8 is communicated and installed with the corresponding piston cylinder 53. A connecting pipe 55 is provided between the airbag 52 and the corresponding piston cylinder 53. One end of the connecting pipe 55 is communicated and installed with the airbag 52, and the other end of the connecting pipe 55 is communicated and installed with the corresponding piston cylinder 53 through a second one-way valve 56. Several exhaust thin pipes 57 are communicated and installed at the top end of the airbag 52, and the top end of each exhaust thin pipe 57 extends to the top side of the outer shell 8. A piston plate 58 is installed inside the piston cylinder 53, and the first one-way valve 54 is located above the corresponding piston plate 58. The first piston plate 58 divides the internal space of the corresponding piston cylinder 53 into two parts. Air is filled on both sides of the piston plate 58. At the central position of the bottom end of the piston plate 58, an elastic pull rope 59 is fixedly installed. The bottom end of the elastic pull rope 59 is inserted into the corresponding chute 9 and fixedly connected to the corresponding heat insulation block 41. The elastic pull rope 59 penetrates through the corresponding piston cylinder 53 and is slidably connected to the corresponding piston cylinder 53 and the outer shell 8. A sealing ring 510 for blocking the gap between the elastic pull rope 59 and the corresponding piston cylinder 53 is provided between the elastic pull rope 59 and the cylinder wall of the corresponding piston cylinder 53. Through the expansion and deformation of the airbag 52, the upper shell 21 is simultaneously pushed downward from the four surrounding sides of the top side of the upper shell 21. Through the mutual cooperation of the first one-way valve 54, the second one-way valve 56 and the connecting pipe 55, the gas in the piston cylinder 53 flows into the airbag 52 unidirectionally, and the air in the airbag 52 is discharged to the outside through the exhaust thin pipe 57 to form a directional gas path, so that the airbag 52 can automatically return to its original state after expansion. The setting of the elastic pull rope 59 enables the heating plate 10 to automatically pull the piston plate 58 downward during the movement, and the piston plate 58 is automatically reset by the gas on the lower side of the piston plate 58.

[0036] According to Figure 1 、 Figure 2 and Figure 5As shown in the figure, the heat insulation component 4 is installed between the adjustment component 5 and the corresponding cooling component 3 and the corresponding heating plate 10. The heat insulation component 4 includes a heat insulation block 41, which is fixedly installed at one end of the corresponding heating plate 10 located in the corresponding chute 9, and the heat insulation block 41 is in contact with the inner wall of the corresponding chute 9. The heat insulation block 41 is threadedly connected to the output end of the corresponding second hydraulic rod 11. One end of the heat insulation tube 31 close to the corresponding heating plate 10 is fixedly provided with a first heat conducting plate 42. A heat storage solution is filled in the heat insulation tube 31. The heat storage solution stores the heat conducted into the heat storage solution and expands correspondingly with the increase of the temperature of the heat storage solution. One end of the first heat conducting plate 42 is in contact with the corresponding heating plate 10, and a number of second heat conducting plates 43 are fixedly installed at the other end of the first heat conducting plate 42. A large number of honeycomb-shaped holes are formed on the second heat conducting plates 43. The heat conduction between the heating plate 10 and the second hydraulic rod 11 is isolated by the heat insulation tube 31. The setting of the first heat conducting plate 42 enables heat conduction to occur between the heating plate 10 and the heat storage solution in the heat insulation tube 31 when the heating plate 10 retracts into the chute 9. The honeycomb-shaped holes on the second heat conducting plates 43 increase the contact area between the second heat conducting plates 43 and the heat storage solution.

[0037] Working principle: During the hot melt welding process of the upper shell 21 and the lower shell 22 of the power adapter 2, first, the lower shell 22 is inserted into the placement groove of the base 1, and then the upper shell 21 is inserted into the outer shell 8 until the top side of the upper shell 21 contacts the inner top side of the outer shell 8. At this time, the outer shell 8 is fixed in the outer shell 8 by the frictional force between the outer shell 8 and the upper shell 21. Then, the first hydraulic rod 6 and the second hydraulic rod 11 are started simultaneously. The second hydraulic rod 11 stretches to push the heating plate 10 out of the chute 9. A number of heating plates 10 form a complete rectangular ring, and the top side of the heating plate 10 contacts the bottom end of the upper shell 21, further limiting and supporting the upper shell 21 in the outer shell 8;

[0038] During the movement of the heating plate 10, the piston plate 58 will be pulled downward through the elastic drawstring 59. As the piston plate 58 moves downward, the piston plate 58 will compress the air at the bottom of the piston cylinder 53, and at the same time, a negative pressure will be generated at the top of the piston cylinder 53. At the same time, the outside air will be inhaled into the piston cylinder 53 through the first one-way valve 54 to make the air refill the upper part of the piston plate 58;

[0039] The first hydraulic rod 6 stretches and pushes the outer shell 8 to move downward. After the outer shell 8 contacts the base 1, the lower shell 22 contacts the heating plate 10. Subsequently, the heating plate 10 is started. The high temperature emitted by the heating plate 10 softens the joint surface of the upper shell 21 and the bonding surface of the lower shell 22 by heating. At the same time, the heat conduction block 32 in contact with the lower shell 22 and the upper shell 21 absorbs the heat conducted from the bonding surface to other positions of the upper shell 21 and the lower shell 22, and continuously conducts the heat into the heat storage solution in the heat insulation tube 31 for preheating the heat storage solution. And due to the characteristics of the rubber of the upper shell 21 and the lower shell 22, a large amount of heat will not be conducted to the outside from the bonding surface, and the heat storage solution will not undergo obvious expansion deformation. At this time, the heat conduction block 32 is closely attached to the outer walls of the upper shell 21 and the lower part. After the bonding surfaces of the upper shell 21 and the lower shell 22 are heated and softened, the operation of the heating plate 10 is stopped and the second hydraulic rod 11 contracts. The second hydraulic rod 11 pulls the heating plate 10 back into the chute 9 to reset the heating plate 10. Due to the non-sticking coating of the heating plate 10, the heating plate 10 will not stick to the softened parts of the upper shell 21 and the lower shell 22. And due to the restraint of the heat conduction block 32, the driving of the softened parts of the upper shell 21 and the lower shell 22 by the moving heating plate 10 will not cause the softened parts to deform. After the heating plate 10 is reset, the end faces of the heating plate 10, the heat insulation tube 31 and the heat conduction block 32 form a complete plane;

[0040] When the heating plate 10 is reset, the pulling state of the heating plate 10 on the piston plate 58 is released, and the pushing and compressing state of the piston plate 58 on the air at the bottom of the piston cylinder 53 is released. The air below the piston plate 58 expands and resets, thereby increasing the air pressure at the top of the piston cylinder 53. The air at the top of the piston cylinder 53 flows into the connecting pipe 55 from the second one-way valve 56, and the connecting pipe 55 quickly conducts the gas into the airbag 52. At this time, the gas quickly and in large quantities flows into the airbag 52 from the connecting pipe 55. At the same time, the gas in the airbag 52 is slowly and in small quantities discharged to the outside through the exhaust capillary 57. The overall pressure in the airbag 52 increases, and the airbag 52 expands and deforms, pushing the upper shell 21 downward. The upper shell 21 moves downward along the inner wall of the outer shell 8 until the bonding surface of the upper shell 21 contacts the bonding surface of the lower shell 22. And due to the blockage of the contact gap between the upper shell 21 and the lower shell 22 by the heating plate 10, the softened part at the bonding surface will not flow outside the housing of the power adapter 2;

[0041] After the heating plate 10 is reset, the first heat conduction plate 42 contacts the heating plate 10, and the residual heat on the heating plate 10 is introduced into the heat storage solution in the heat insulation tube 31 by the first heat conduction plate 42 and the second heat conduction plate 43, and the process is slow. According to the above, after the bonding surface of the upper shell 21 and the lower shell 22 comes into contact, as the gas at the exhaust capillary 57 continues to be discharged, the pressure in the airbag 52 continues to decrease. After the pressure in the airbag 52 and the pressure in the piston cylinder 53 return to normal, since the thrust in the airbag 52 disappears, the airbag 52 contracts and resets, which is also a slower process. According to the above, as a large amount of residual heat on the heating plate 10 is introduced into the heat storage solution, the temperature of the heat storage solution in the heat insulation tube 31 rises, which in turn causes the volume of the heat storage solution to expand and pushes the heat conduction block 32 outward from the heat conduction tube, so that the heat conduction block 32 clamps the upper shell 21 and the lower shell 22 from all directions to constrain and limit the upper shell 21 and the lower shell 22, so that the bonding surface of the upper shell 21 and the bonding surface of the lower shell 22 still fit tightly together when the pushing force of the airbag 52 is lost. At the same time, part of the heat on the heat conduction block 32 and the heating plate 10 is conducted into the bonding surface of the upper shell 21 and its surrounding part and the bonding surface of the lower shell 22 and its surrounding part, prolonging the cooling time of the bonding surface of the upper shell 21 and the bonding surface of the lower shell 22, so that the bonding surface of the upper shell 21 and the bonding surface of the lower shell 22 can have sufficient time to contact and bond until the upper shell 21 and the lower shell 22 are cooled, the upper shell 21 and the lower shell 22 are welded together, and at the same time the heat storage solution in the heat insulation tube 31 is cooled, the thrust of the heat storage solution on the heat conduction block 32 disappears, and all components of the device are reset;

[0042] At this time, the first hydraulic rod 6 is contracted, the outer shell 8 is separated from the base 1, and the power adapter 2 after welding is driven to rise together with the friction force between the upper shell 21 and the inner wall of the outer shell 8. At this time, the welded power adapter 2 can be pulled out of the outer shell 8. According to the above, the upper shell 21 and the lower shell 22 are reinserted into the outer shell 8 and the base 1 to continue welding the next power adapter 2.
