Description

Technical Field

[0001] This utility model relates to the field of injection molding technology, and in particular to an automatic splicing device for LED bracket injection molding. Background Technology

[0002] The joint of the material strip is formed by bonding and pressing two separate material strips together. This joint is thick and has a destructive effect on the extrusion molding of the injection mold.

[0003] The existing material strip joint requires manual intervention to pass through the injection molding machine. Specifically, the material strip joint needs to be manually pulled downwards to offset it from the mold. The disadvantages are that it is time-consuming, labor-intensive, inefficient, and poses certain safety hazards. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing an automatic LED bracket injection molding and splicing device. This invention can solve problems such as low efficiency of manual joint handling, safety hazards of manual high-altitude operations, and material waste, and is easy to automate, replacing manual labor.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] An automatic injection molding and splicing device for LED brackets includes a splicing platform. An injection mold is installed inside the splicing platform. A guide device for the material strip to pass through is installed at the upper end of the injection mold. A detection device for detecting the thickness of the material strip is also installed at the upper end of the splicing platform. The detection device includes at least two spaced detection wheels that are elastically connected. The material strip passes through the two detection wheels during movement. A material pulling device is installed at the lower end of the injection mold. The material pulling device is electrically connected to the detection device to pull the material strip with abnormal thickness away from the injection mold.

[0007] Preferably, the detection device further includes a detection housing, in which a first detection mounting plate and a second detection mounting plate are disposed, the first detection mounting plate and the second detection mounting plate are elastically connected by an elastic rod, and the two detection wheels are rotatably connected to the corresponding detection mounting plates respectively.

[0008] Preferably, the detection housing is arranged at an angle toward the guide device.

[0009] Preferably, an elastic telescopic rod is provided between the lower end of the detection housing and the upper end of the insertion platform.

[0010] Preferably, the material pulling device includes a material pulling locking component and a driving component for driving the material pulling locking component to move up and down.

[0011] Preferably, the injection mold includes a first template and a second template, and an injection molding machine is disposed on the outside of the first template.

[0012] Preferably, the guiding device includes a guide head, and the upper end of the guide head is provided with an X-axis positioning control joint, a Y-axis positioning control joint and a Z-axis positioning control joint.

[0013] Compared with the prior art, the advantages of this utility model are as follows:

[0014] Because the strip joint is thicker than the normal strip, when the strip joint passes the detection wheel, it will raise the detection wheel. The sensor will detect the raising and immediately send feedback to the feeding machine. After receiving the feedback, the feeding machine will pull the strip joint to the bottom of the mold according to the length value set in the program, so as to avoid damage to the mold caused by injection molding at the strip joint.

[0015] Compared to existing manual handling of material strip joints, this patent can ① quickly resolve material strip joints and pass through the mold without stopping the machine; ② eliminate the need to climb to the top of the injection molding machine to operate, as this patent will automatically operate after detecting the joint without manual intervention; ③ be applicable to different models and specifications of material strips, and the pulling distance of the feeding machine can be preset to avoid excessive pulling and resulting material waste.

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 are described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a full understanding of this utility model. However, this utility model can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this utility model. Therefore, this utility model is not limited to the specific embodiments disclosed below.

[0022] It should be noted that when an element is referred to as being "fixed to" another element, it can be directly attached to the other element or there may be an intervening element. When an element is referred to as being "connected to" another element, it can be directly connected to the other element or there may be an intervening element. The terms "vertical," "horizontal," "left," "right," and similar expressions used herein are for illustrative purposes only and do not represent the only possible implementation.

[0023] To address the technical problems mentioned in the background section, see Appendix Figure 1 -Appendix Figure 4 The LED bracket injection molding automatic threading equipment includes a threading platform 300, an injection mold 400 is set inside the threading platform 300, and a guide device 700 is set at the upper end of the injection mold 400 for the feeding belt 200 to pass through. The guide device 700 can guide the feeding belt 200, change the moving direction of the feeding belt 200, and allow the feeding belt 200 to be pulled into the injection mold 400 for injection molding.

[0024] The injection mold 400 includes a first mold plate 410 and a second mold plate 420. An injection molding machine 500 is arranged on the outside of the first mold plate 410. During the movement of the material strip 200, the first mold plate 410 and the second mold plate 420 are controlled to be staggered. The material strip 200 passes down normally to realize material loading and unloading. After the material strip 200 moves to the position where it is not being injected and is between the first mold plate 410 and the second mold plate 420, the first mold plate 410 and the second mold plate 420 are controlled to stick together and squeeze. After sticking and squeezing, the injection molding machine 500 squeezes the molten injection molding material into the space between the first mold plate 410 and the second mold plate 420. After cooling, solid injection molding material is formed on the outside of the material strip 200.

[0025] A material tray 100 is also provided on the outside of the threading platform 300 for pulling and feeding the material strip 200. The material strip 200 is formed by bonding and pressing multiple individual material strips 200 together, and the thickness at the joint is greater than the thickness at other locations.

[0026] A detection device 600 for detecting the thickness of the strip 200 is also provided at the upper end of the threading platform 300. The detection device 600 includes at least two detection wheels 660 spaced apart. The two detection wheels 660 are elastically connected, and the strip 200 passes through the two detection wheels 660 during movement. Through the above structural design, after the part of the strip 200 with abnormal surface thickness moves between the two detection wheels 660, it can push the two detection wheels 660 away from each other. The detection of the strip 200 with abnormal thickness is achieved in the above manner.

[0027] A material pulling device 800 is provided at the lower end of the injection mold 400. The material pulling device 800 is electrically connected to the detection device 600 to pull the abnormal thickness strip 200 away from the injection mold 400. In this way, the abnormal thickness strip 200 is pulled to the outside of the injection mold 400 to avoid the abnormal thickness strip 200 from entering the injection mold 400 and damaging the normal pressing and injection of the injection mold 400.

[0028] It should be noted that, with the material strip 200 moving at a constant speed, the time it takes to pass through the injection mold 400 is constant. After the detection device 600 detects the abnormal thickness of the material strip within a predetermined time, the material strip 200 is pulled down by the material pulling device 800 to pull the abnormally thick portion out of the injection mold 400. The distance that the material pulling device 800 pulls down is determined according to the length of the abnormal thickness of the material strip 200.

[0029] Specifically, the detection device 600 also includes a detection housing 610, within which a first detection mounting plate 630 and a second detection mounting plate 650 are disposed. The first detection mounting plate 630 and the second detection mounting plate 650 are elastically connected by an elastic rod 640. Two detection wheels 660 are rotatably connected to their respective detection mounting plates. The second detection mounting plate 650 is located near the bottom and is fixedly connected to the detection housing 610. The first detection mounting plate 630 is connected to the second detection mounting plate 650 via the elastic rod 640 and is in a relatively elastically movable state. A displacement monitoring element is disposed between the second detection mounting plate 650 and the first detection mounting plate 630. This element can be a common optical detection element or a resistance detection element. After detecting an abnormal thickness of the strip 200, an abnormal thickness detection signal is emitted.

[0030] The detection housing 610 is inclined toward the guide device 700. By controlling the inclined arrangement of the detection housing 610, the movement trajectory of the material strip 200 can be adjusted to avoid excessive offset angle of the material strip 200 during bending and movement, thus ensuring normal traction injection of the material strip 200.

[0031] An elastic telescopic rod 620 is provided between the lower end of the detection housing 610 and the upper end of the connecting platform 300. The elastic telescopic rod 620 can provide elastic buffering for the detection housing 610. During the process of the material pulling device 800 pulling the material belt 200 downward, the material tray 100 is in a relatively constant state. The elastic telescopic rod 620 can provide elastic buffering for the excessive pulling.

[0032] The material pulling device 800 includes a material pulling locking component 810 and a drive component 820 for driving the material pulling locking component 810 to move up and down. The material pulling locking component 810 can be selected as a material strip 200 locking or winding structure to avoid the material strip 200 slipping during the descent of the drive component 820, so as to ensure that the material strip 200 with abnormal thickness is pulled out of the injection mold 400.

[0033] The guiding device 700 includes a guide head, with an X-axis position control joint 710, a Y-axis position control joint 720, and a Z-axis position control joint 730 at the upper end of the guide head. The position of the bottom guide head can be adjusted through the above structure, and the position of the guide head can be adaptively adjusted according to the material strip 200 of different properties to meet the injection molding processing requirements under different conditions.

[0034] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
