Detailed Implementation

[0021] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0022] like Figure 1 and Figure 2 As shown, the semi-automatic device for marking the thermostat and riveting the plug of the heater 200 provided in the embodiment of this application includes a laser marking mechanism 1, a riveting mechanism 2, a first material rack 3 disposed on one side of the laser marking mechanism 1, and a second material rack 4 disposed between the laser marking mechanism 1 and the riveting mechanism 2. The first material rack 3 and the second material rack 4 have the same structure. The first material rack 3 includes a frame 31, several material boxes 32, and several layers of conveyor lines 33 disposed on the frame 31 for conveying the material boxes 32. The conveyor lines 33 include several rollers rotatably connected to the frame 31. The conveyor lines 33 are inclined forward. A stopper 34 is provided on the frame 31 for stopping the material boxes 32 at the lower end of the conveyor lines 33.

[0023] It should be noted that this application involves laser marking the housing 100 and riveting the housing 100 to the heater 200. Both the laser marking mechanism 1 and the riveting mechanism 2 are controlled by the PLC control system and are equipped with start operation buttons.

[0024] In actual use, the housing 100 is placed in the material box 32 of the first material rack 3. The operator removes the housing 100 from the material box 32 and places it in the laser marking mechanism 1, then presses the start button to perform laser marking. The operator then transfers the heater 200 to the riveting mechanism 2. After laser marking is completed, the operator transfers the marked housing 100 to the riveting mechanism 2, pre-assembling the housing 100 and the heater 200. Subsequently, the riveting mechanism 2 completes the riveting of the heater 200 and the housing 100. The material handling principle for the housing 100 in the first material rack 3 and the heater 200 in the second material rack 4 is the same. Taking the housing 100 as an example: the housing 100 is placed in the material box 32. The operator removes the housing 100 from the frontmost material box 32. After the frontmost material box 32 has been depleted, it is removed from the conveyor line 33. The subsequent material boxes automatically roll forward along the conveyor line 33 to the stop rack 34 and continue feeding.

[0025] In the above design, the entire process involves manual loading and unloading, automatic marking of the housing 100 by the laser marking machine 15, and automatic riveting of the heater 200 to the housing 100 by the riveting mechanism 2. The entire equipment does not require a robotic arm for transfer. The No. 1 material rack 3 and the No. 2 material rack 4 can automatically transport the housing 100 and the heater 200 to the operator's pick-up position through the inclined design of the conveyor line 33, which can ensure the convenience of picking up materials.

[0026] Specifically: such as Figure 3 As shown, the laser marking mechanism 1 includes a first frame 11 disposed between the first material rack 3 and the second material rack 4, a first photoelectric switch 12 disposed on the first frame 11, a first tooling 13 disposed on the first frame 11, a laser marking machine 15 disposed on the first frame 11, and a dust extraction assembly 14.

[0027] During actual marking, the operator places the housing 100 on fixture 13 and presses the start button. The laser marking machine 15 then initiates the marking program via the PLC control system: the photoelectric switch detects the housing 100 on fixture 13, and the laser marking machine 15 marks the surface of the housing 100. The dust extraction component 14 collects the dust generated during the marking process. The laser marking machine 15 automatically stops operating after one marking cycle is completed.

[0028] In the above design, the structural design and specific implementation of the laser marking machine 15 can effectively realize automatic marking on the housing 100.

[0029] Specifically: such as Figure 3 As shown, the dust extraction assembly 14 includes a smoke purifier 141 and an exhaust pipe 142 disposed on one side of the first frame 11. The air outlet of the exhaust pipe 142 is connected to the smoke inlet of the smoke purifier 141, and the air inlet of the exhaust pipe 142 is located above the first tooling 13.

[0030] In actual use, the smoke purifier 141 uses a built-in fan to draw away the smoke and dust generated during the laser marking process along the exhaust pipe 142.

[0031] In the above design, the structural design and specific implementation of the dust extraction component 14 facilitate the effective extraction of smoke and ensure a clean working environment.

[0032] Specifically: such as Figure 5 As shown, the first tooling 13 includes a first base plate 131, first handles 132 disposed on both sides of the first base plate 131, and first positioning pins 133 disposed on the first base plate 131. The lower end face of the first base plate 131 is provided with several first positioning grooves, and the first frame 11 is provided with several first positioning pins corresponding to the first positioning grooves. The first base plate 131 is provided with a first contouring groove for supporting the housing 100.

[0033] In actual use, the housing 100 is placed in the first contouring groove, and the first tooling 13 is positioned on the first frame 11 by the first positioning pin and the first positioning groove. When it is necessary to transfer the first tooling 13, the operator holds the two first handles 132 with both hands to remove the first tooling 13 from the first frame 11 and transfer it.

[0034] In the above design, the structural design and specific implementation of tooling 13 can effectively support the shell 100 when laser marking, and facilitate the movement of tooling 13.

[0035] Specifically: such as Figure 4 As shown, the riveting mechanism 2 includes a second frame 21 disposed on the side of the second material rack 4 away from the laser marking mechanism 1, a second photoelectric switch 22 disposed on the second frame 21, a second support 23 disposed on the second frame 21, an electric cylinder 24 disposed on the second support 23, a lifting assembly 25 slidably disposed on the second support 23, a pressure head 26 disposed on the lifting assembly 25, a pressure sensor 27 connecting the upper end of the pressure head 26 and the output end of the electric cylinder 24, and a second tooling 28 disposed on the second frame 21.

[0036] Before actual riveting, the heater 200 is placed on fixture 28, and then the housing 100 is placed on fixture 28 and pre-assembled with the heater 200. Photoelectric switch 22 detects the presence of the housing 100. At this time, fixture 28 supports the housing 100 with the pre-assembled heater 200. Pressing the start button starts the riveting procedure via the PLC control system: then, the electric cylinder 24 drives the lifting assembly 25 to move the pressure head 26 downwards, applying pressure to the heater 200 to complete the riveting between the heater 200 and the housing 100. During the riveting process, pressure sensor 27 monitors the riveting pressure applied by the electric cylinder 24 to the product.

[0037] In the above design, the structural design and specific implementation of the riveting mechanism 2 facilitate the rapid riveting of the heater 200 and the housing 100.

[0038] Specifically: such as Figure 6 As shown, the second tooling 28 includes a second base plate 281, second handles 282 on both sides of the second base plate 281, a support base 283 with through holes and contour grooves, several springs 284 connecting the lower end face of the support base 283 and the upper end face of the second base plate 281, columns 285 fixedly mounted on the second base plate 281 and passing through the through holes, several second positioning posts on the second frame 21, and a second positioning groove corresponding to the second positioning posts at the lower end of the second base plate 281. The columns 285 are provided with vertical grooves 201.

[0039] Before actual riveting, the heater 200 is placed on the column 285, so that the column 285 supports the heater 200 and a part of the heater 200 extends into the vertical groove 201. Then, the housing 100 is placed in the contour groove, so that the upper end of the heater 200 contacts the protruding part inside the housing 100. Then, the electric cylinder 24 drives the pressure head 26 to press the protrusion of the housing 100 downward. During the pressing process, the spring 284 is compressed, the support seat 283 moves down, and the heater 200 is fixed on the column 285 until the protrusion is riveted to the heater 200. Afterward, the electric cylinder 24 drives the pressure head 26 to return to its original position, and the spring 284 returns to its original position.

[0040] In the above design, the structural design and specific implementation of tooling 28 can effectively support the heater 200 and the housing 100, and ensure that the housing 100 is buffered by the spring 284 during the riveting process between the housing 100 and the heater 200, thereby reducing the impact of the pressure head 26 on the housing 100.

[0041] Specifically: the second support 23 includes several support columns set on the second frame 21 and an mounting plate connecting the upper surfaces of the several support columns; the lifting assembly 25 includes several linear bearings and a connecting plate connecting the several linear bearings; the pressure head 26 is set on the connecting plate; and the linear bearing is sleeved on the support column.

[0042] In actual use, the electric cylinder 24 drives the pressure head 26 to move the lifting assembly 25 up and down synchronously. When the lifting assembly 25 moves up and down, it slides along the support column through the linear bearing, which drives the connecting plate to move up and down synchronously.

[0043] In the above design, the structural design of the second support 23 and the lifting assembly 25 facilitates the guidance of the pressure head 26 during the lifting process, ensuring that the pressure head 26 does not deviate when it moves.

[0044] In further detail, it should be understood that the above description is only a specific embodiment of the present utility model and is not intended to limit the present utility model. 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.
