Description

Technical Field

[0001] This utility model relates to the field of plastic hot melt welding technology, and in particular to a plastic welding device with a matching halogen lamp baking device. Background Technology

[0002] Hot melt welding is a commonly used welding process in the welding of thermoplastic products. It works by passing light through the upper translucent material and shining it on the lower light-absorbing material. The welding surface of the light-absorbing material melts and adheres to the welding surface of the upper material. After the melted part cools and hardens, the two plastic products are firmly welded together.

[0003] When performing thermoplastic welding, the most important thing to be careful about is to avoid exposing the non-welding parts of the light-absorbing material to light, which could cause them to melt. This would result in the plastic product being burned and reduce the quality of the thermoplastic welding process.

[0004] When performing thermoplastic welding, existing thermofusion welding equipment has difficulty in precisely controlling the range of light irradiation. This can cause some light to shine on non-welding areas, resulting in these areas melting and burning, which reduces the quality of the welding process.

[0005] To solve the above problems, there is an urgent need for a plastic welding device that can be matched with a halogen lamp baking device. Utility Model Content

[0006] The purpose of this utility model is to provide a plastic welding device with a matching halogen lamp baking device, so as to solve the problem mentioned in the background art that when the hot melt welding device is performing thermoplastic welding, the range of light irradiation is difficult to control precisely, which will cause some light to irradiate the non-welding area and cause the area to melt, thereby burning the non-welding area and reducing the welding quality.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a plastic welding device with a halogen lamp baking apparatus, comprising a workbench, a light-transmitting welding component, and a light-absorbing welding component. The light-transmitting welding component is placed on top of the light-absorbing welding component. A hydraulic cylinder is fixedly connected to the bottom of the workbench via a first fixed plate. The output end of the hydraulic cylinder passes through the first fixed plate and the top surface of the workbench and is fixedly connected to a lifting plate. The light-absorbing welding component is installed on the top surface of the lifting plate. A second fixed plate is fixedly connected to the top surface of the workbench. A light-shielding component is connected to the second fixed plate. A longitudinal displacement component is connected to the top of the workbench via two pairs of support columns. A transverse displacement component is connected to the longitudinal displacement component. A halogen lamp module is connected to the transverse displacement component.

[0008] The light-shielding component can block the non-welded area based on the welding area between the light-transmitting welded part and the light-absorbing welded part.

[0009] Preferably, the light-shielding assembly includes a fixed frame detachably mounted on the top surface of the second fixed plate. The top of the second fixed plate has a second cavity located directly below the fixed frame. A light-shielding plate is fixedly connected to the inner sidewalls of the fixed frame via multiple connecting ribs. A truncated pyramidal inner pressure block is fixedly connected to the bottom of the light-shielding plate. The top surface area of ​​the inner pressure block is smaller than the top surface area of ​​the light-shielding plate, and the bottom surface area of ​​the inner pressure block is larger than the top surface area of ​​the light-shielding plate. The light-shielding plate can block the non-welding area between the light-transmitting welded part and the light-absorbing welded part. The bottom surface of the inner pressure block can press tightly against the top surface of the light-transmitting welded part. The advantage of this arrangement is that the non-welding position between the light-transmitting welded part and the light-absorbing welded part can be blocked by the light-shielding plate and the inner pressure block. This ensures that when the longitudinal displacement assembly and the transverse displacement assembly move the halogen lamp module along the welding contour, the light emitted by the halogen lamp module will not illuminate the non-welding part. This avoids the non-welding part from being heated and burned after being illuminated, effectively improving the welding quality of the welding equipment.

[0010] Preferably, the number of connecting ribs is not less than six, and the thickness of the connecting ribs is not less than one-fifteenth of the length of the fixed frame. The advantage of this setting is that it ensures that the connecting ribs can firmly fix the light-shielding plate to the inner wall of the fixed frame. This ensures that the position of the light-shielding plate can remain stable when it is pressed against the top of the light-transmitting welded part with the inner pressure block. This ensures that the welding position between the light-transmitting welded part and the light-absorbing welded part can be firmly and stably pressed together, thus ensuring the welding processing quality of the equipment.

[0011] Preferably, the connecting rib is made of transparent plastic. This design allows the light emitted by the halogen lamp module to pass smoothly through the connecting rib and the inner pressure block and illuminate the welding contour, thereby ensuring that the welding work can be carried out smoothly and reliably.

[0012] Preferably, the fixing frame is fixedly connected to the top surface of the second fixing plate by multiple bolts. The advantage of this arrangement is that the light-shielding component can be easily disassembled and replaced by turning the bolts. This facilitates the replacement of the corresponding light-shielding component when welding parts with different welding profiles, thereby improving the ease of operation and practicality of the welding equipment.

[0013] Preferably, the halogen lamp module includes a housing fixedly connected to the lateral displacement component. A lamp tube is fixedly inserted into the inner top wall of the housing, and a lens is fixedly connected to the bottom of the housing. The inner top wall of the housing is an inverted bowl shape, and a reflector bowl is fixedly fitted onto the inner top wall of the housing. The advantage of this arrangement is that the reflector bowl can reflect the halogen light emitted by the lamp tube to the lens, and then the lens can concentrate the light into a very small area. This allows the light emitted by the lamp tube to be concentrated and accurately illuminated on the welding contour, further improving the welding quality and performance of the welding equipment.

[0014] In summary, the technical effects and advantages of this utility model are as follows:

[0015] 1. In this utility model, the light-shielding component can block the non-welding area between the light-transmitting welded part and the light-absorbing welded part, thus preventing the light emitted by the halogen lamp module from shining on the non-welding part and avoiding burns to the non-welding parts of the light-transmitting and light-absorbing welded parts, thereby improving the quality of the welding process. In addition, the longitudinal displacement component and the transverse displacement component drive the halogen lamp module to move precisely along the welding contour, thereby ensuring that the light-transmitting welded part and the light-absorbing welded part are accurately and reliably welded together, thus effectively improving the quality of the welding process of the welding equipment.

[0016] 2. In this utility model, the halogen lamp module is designed so that the reflector bowl can reflect the halogen light emitted by the lamp tube to the lens. Then the lens can concentrate the light into a very small area, so that the light emitted by the lamp tube can be concentrated and accurately irradiated on the welding contour, further improving the welding quality and performance of the welding equipment.

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] Please refer to Figures 1-7 The plastic welding equipment shown includes a workbench 1, a light-transmitting welding component 21, and a light-absorbing welding component 22. The light-transmitting welding component 21 is placed on top of the light-absorbing welding component 22. A hydraulic cylinder 32 is fixedly connected to the bottom of the workbench 1 through a first fixing plate 31. The output end of the hydraulic cylinder 32 passes through the first fixing plate 31 and the top surface of the workbench 1 and is fixedly connected to a lifting plate 33. The light-absorbing welding component 22 is installed on the top surface of the lifting plate 33. A second fixing plate 4 is fixedly connected to the top surface of the workbench 1. A light-shielding component 5 is connected to the second fixing plate 4. A longitudinal displacement component 7 is connected to the top of the workbench 1 through two pairs of support columns 6. A transverse displacement component 8 is connected to the longitudinal displacement component 7. A halogen lamp module 9 is connected to the transverse displacement component 8.

[0028] The light-shielding component 5 can block the non-welding area based on the welding area between the light-transmitting welded component 21 and the light-absorbing welded component 22;

[0029] The longitudinal displacement component 7 drives the lateral displacement component 8 to move back and forth along the longitudinal direction, and the lateral displacement component 8 drives the halogen lamp module 9 to move left and right along the lateral direction.

[0030] Both the longitudinal displacement component 7 and the transverse displacement component 8 are driven by servo motors to move the ball screws, and the servo motors are connected to the controller installed on the worktable 1.

[0031] refer to Figures 1-6 The light-shielding component 5 includes a fixing frame 51 that is detachably mounted on the top surface of the second fixing plate 4. The top of the second fixing plate 4 has a second cavity located directly below the fixing frame 51. A light-shielding plate 52 is fixedly connected between the inner sidewalls of the fixing frame 51 by multiple connecting ribs 53. A frustum-shaped inner pressure block 54 is fixedly connected to the bottom of the light-shielding plate 52. The top surface area of ​​the inner pressure block 54 is smaller than the top surface area of ​​the light-shielding plate 52, and the bottom surface area of ​​the inner pressure block 54 is larger than the top surface area of ​​the light-shielding plate 52. The light-shielding plate 52 can block the non-welding area between the light-transmitting welded component 21 and the light-absorbing welded component 22. The bottom surface of the inner pressure block 54 can press tightly against the top surface of the light-transmitting welded component 21.

[0032] Specifically, the light shield 52 and the inner pressure block 54 can block the non-welding position between the light-transmitting weldment 21 and the light-absorbing weldment 22. This ensures that when the longitudinal displacement component 7 and the transverse displacement component 8 move the halogen lamp module 9 along the welding contour, the light emitted by the halogen lamp module 9 will not illuminate the non-welding part. This prevents the non-welding part from being heated and burned after being illuminated, effectively improving the welding quality and performance of the welding equipment.

[0033] refer to Figure 4 and Figure 5 The number of connecting ribs 53 shall not be less than six, and the thickness of the connecting ribs 53 shall not be less than one-fifteenth of the length of the fixed frame 51.

[0034] Specifically, the connecting rib 53 is designed to securely fix the light-shielding plate 52 to the inner wall of the fixed frame 51. This ensures that the position of the light-shielding plate 52 remains stable when it is pressed against the top of the light-transmitting welded part 21 by the inner pressure block 54. This ensures that the welding position between the light-transmitting welded part 21 and the light-absorbing welded part 22 can be firmly and stably pressed together, thus ensuring the welding quality of the equipment.

[0035] refer to Figure 4 and Figure 5 The connecting rib 53 is made of transparent plastic.

[0036] Specifically, this allows the light emitted by the halogen lamp module 9 to pass smoothly through the connecting rib 53 and the inner pressure block 54 and illuminate the welding contour, thereby ensuring that the welding work can be carried out smoothly and reliably.

[0037] refer to Figure 1 and Figure 2The fixed frame 51 is fixedly connected to the top surface of the second fixed plate 4 by multiple bolts.

[0038] Specifically, the light-shielding component 5 can be easily disassembled and replaced by turning the bolts, which makes it convenient to replace the corresponding light-shielding component 5 when welding parts with different welding profiles, thereby improving the ease of operation and practicality of the welding equipment.

[0039] refer to Figure 6 and Figure 7 The halogen lamp module 9 includes a housing 91 fixedly connected to the lateral displacement component 8, a lamp tube 92 fixedly inserted into the inner top wall of the housing 91, a lens 93 fixedly connected to the bottom of the housing 91, the inner top wall of the housing 91 being an inverted bowl shape, and a reflector bowl 94 fixedly sleeved on the inner top wall of the housing 91.

[0040] Specifically, the reflector bowl 94 can reflect the halogen light emitted by the lamp tube 92 to the lens 93, and then the lens 93 can concentrate the light into a very small area. This allows the light emitted by the lamp tube 92 to be concentrated and accurately illuminate the welding contour, further improving the welding quality and performance of the welding equipment.

[0041] Working principle: The light-absorbing welding component 22 is installed on the top surface of the lifting plate 33, and then the light-transmitting welding component 21 is placed on the top surface of the light-absorbing welding component 22, so that the welding surfaces between the light-absorbing welding component 22 and the light-transmitting welding component 21 are aligned.

[0042] Subsequently, a light-shielding component 5 corresponding to the light-absorbing weldment 22 and the light-transmitting weldment 21 is selected and fixedly connected to the top surface of the second fixing plate 4 by bolts.

[0043] Next, the hydraulic cylinder 32 is activated to drive the lifting plate 33 to move upward. The lifting plate 33 drives the light-absorbing welded part 22 and the light-transmitting welded part 21 to move upward until the bottom surface of the inner pressure block 54 is pressed tightly against the top surface of the light-transmitting welded part 21. This allows the welding surfaces between the light-absorbing welded part 22 and the light-transmitting welded part 21 to be pressed tightly together.

[0044] Then, the longitudinal displacement component 7 is activated to drive the transverse displacement component 8 to move back and forth along the longitudinal direction. The transverse displacement component 8 drives the halogen lamp module 9 to move left and right along the transverse direction. This allows the halogen lamp module 9 to move precisely along the welding contour, so that the light emitted by the halogen lamp module 9 can accurately illuminate the welding contour, thereby ensuring the quality of the welding process.

[0045] Finally, it should be noted that the above are merely preferred embodiments of the present utility model and are 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.
