[0021] In order to enable those skilled in the art to better understand the technical solutions in this application, the technical solutions in the embodiments of this application will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of this application. Obviously, the described embodiments are only a part of the embodiments of this application, rather than all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the scope of protection of this application.

[0022] Material tapes are widely used in existing chip mounters. Electronic components for chip mounting are arranged in sequence on the material tape. Usually, a plastic film is also covered on the material tape to protect the electronic components from being affected by the outside world during storage and transportation, such as dust, moisture, etc. It can effectively prevent the electronic components from being damaged or contaminated before chip mounting, and maintain the cleanliness and integrity of the electronic components.

[0023] The plastic film on the existing material tape is usually removed only before finally reaching the suction nozzle picking position before chip mounting to maximize the functional role of the plastic film. However, the existing plastic film usually droops below the feeder handle and is manually torn off after the final chip mounting of this material tape and discarded in the waste storage box.

[0024] Refer to Figure 1 , Figure 2 As shown in [relevant figure numbers], in one of the embodiments, a material tape purging structure is provided, including a receiving box 20. The receiving box 20 is arranged below the installation position of the feeder 10 of the chip mounter. The receiving box 20 includes an upper opening 21 for receiving the plastic film of the material tape 30 and a lower opening for guiding out the plastic film of the material tape 30. The lower opening of the receiving box 20 is conductively connected to the waste box.

[0025] It should be noted that the material receiving box 20 is arranged below the installation position of the feeder 10, which facilitates timely receipt of the plastic film falling from the material tape 30. It can ensure that after the electronic components on the material tape 30 are picked up and mounted, the plastic film can directly fall into the material receiving box 20 without the need to additionally move or adjust the position of the material tape 30. Among them, the inner wall of the upper opening 21 of the material receiving box 20 is smooth and can be designed as a smooth inclined plane or arc to reduce the resistance and friction when the plastic film falls. The lower opening is conductively connected to the waste box to ensure that the collected plastic film can be smoothly exported to the waste box. The design of the lower opening should consider the fluidity of the plastic film and possible accumulation problems to avoid blockage. This material tape purging structure will be able to more efficiently handle the plastic film on the material tape 30, reduce the waste management burden of the production line, and improve the cleanliness and safety of the production environment.

[0026] According to the material tape purging structure provided by the present application, compared with the prior art, the beneficial effect is that the material receiving box 20 is arranged below the installation position of the feeder 10 of the chip mounter. The material receiving box 20 includes an upper opening 21 for receiving the plastic film of the material tape 30 and a lower opening for exporting the plastic film of the material tape 30. The lower opening of the material receiving box 20 is conductively connected to the waste box. When the material tape 30 is conveyed to the working position, the plastic film on the material tape 30 is blown into the upper opening 21 of the material receiving box 20 through the purging structure and exported from the lower opening, which can timely clean the plastic film of the scattered material tape 30, improve the stability and safety of the equipment operation, and improve the overall cleanliness.

[0027] Refer to Figure 1 、 Figure 2 As shown in the figure, in one embodiment, a plurality of air blowing openings are provided on the side wall of the material receiving box 20.

[0028] It should be noted that the air blowing openings can generate air flow to help accelerate the process of the plastic film of the material tape 30 falling from the installation position of the feeder 10 into the material receiving box 20. This helps to reduce the hovering time of the plastic film in the air and reduce the risk of entanglement or interference with other components. By reasonably arranging the positions and angles of the air blowing openings, the direction and intensity of the air flow can be precisely controlled, so that the plastic film falls into the material receiving box 20 along a predetermined path. This helps to reduce the scattering and accumulation of the plastic film and improve the collection efficiency.

[0029] Refer to Figure 1 、 Figure 2 As shown in the figure, in one embodiment, the air blowing openings are connected to the conduit for purging air.

[0030] It should be noted that the conduit serves as a transmission channel for purging air.

[0031] Refer to Figure 1 、 Figure 2As shown, in one embodiment, the number of the air outlets is 2 to 20, and the air outlets face the lower opening direction of the material receiving box 20.

[0032] It should be noted that more air outlets can be provided to facilitate uniformly and timely blowing the plastic film into the material receiving box 20.

[0033] Refer to Figure 1 、 Figure 2 As shown, in one embodiment, the other end of the conduit is connected to the exhaust hole 70 of the control cylinder 60 of the patch device.

[0034] It should be noted that the control cylinder 60 and the exhaust hole 70 output air flow into the conduit.

[0035] Refer to Figure 1 、 Figure 2 As shown, in one embodiment, the material belt 30 is controlled to feed step by step by the control cylinder 60, the plastic film is torn off from the material belt 30 according to the step distance of the control cylinder 60, the control cylinder 60 exhausts once every step control, and every time the control cylinder 60 exhausts, the air outlet in the material receiving box 20 is purged by exhausting air through the conduit.

[0036] It should be noted that the material belt 30 realizes step-by-step feeding through the precise control of the control cylinder 60. The control cylinder 60 pushes the material belt 30 forward according to the preset step length and frequency to ensure the accurate position of the material on the production line. At the same time, when the control cylinder 60 feeds step by step, gas is generated, and the generated gas is transported to the air outlet through the exhaust hole 70 and the conduit to blow off the plastic film.

[0037] Refer to Figure 1 、 Figure 2 As shown, in one embodiment, the material belt 30 is controlled to feed step by step by the first control device, the plastic film is torn off from the material belt 30 according to the step distance of the first control device, and the first control device exhausts once every step control;

[0038] The conduit of the air outlet is connected to the second control device, and the second control device exhausts once every step control. The step control time of the second control device is an integer multiple of the step control time of the first control device.

[0039] It should be noted that by controlling the step-by-step feeding and exhaust frequency of the material belt 30, the plastic film can be blown off in time.

[0040] Refer to Figure 1 、 Figure 2 As shown, in one embodiment, a conduit for purging air is fixed on the side wall of the material receiving box 20.

[0041] It should be noted that the main function of the conduit is to convey the purging air to a specified position inside the material receiving box 20 and eject it at a certain speed and angle, so as to achieve the purging of the materials inside the material receiving box 20.

[0042] Refer to Figure 1 、 Figure 2 As shown, in one of the embodiments, the other end of the conduit is connected to the purging cylinder, and the purging cylinder periodically performs purging control inside the material receiving box 20 through the conduit.

[0043] It should be noted that the purging cylinder can be triggered according to a preset time interval or condition, and release high-pressure or high-speed air flow inside the material receiving box 20 through the conduit. This timed purging mechanism ensures the continuous cleaning inside the material receiving box 20 and prevents problems such as material accumulation and impurity accumulation.

[0044] It should be noted that when an element is referred to as "fixed to" or "disposed on" another component, it can be directly on the other component or indirectly disposed on the other component; when a component is referred to as "connected to" another component, it can be directly connected to the other component or indirectly connected to the other component.
