Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of sorting machines, in particular to a novel ejector pin device for a sorting machine. Background Art
[0002] After the ejector pin of the existing ejector pin structure contacts and breaks the blue film, blue film residue may remain at the tip of the ejector pin. Then, during the process of ejecting the die, the blue film residue may stick to the back of the die, causing the die to be skewed or uneven after solidification, which in turn causes the risk of die retrieval failure at the package end or abnormal welding wires.
[0003] For this purpose, a new type of ejector pin device for sorting machine is proposed. Utility Model Content
[0004] The purpose of the utility model is to solve the problem of residual glue on ejector pins generated during the sorting process, and the utility model provides a novel ejector pin device for a sorting machine.

[0006] A novel ejector device for a sorting machine comprises an ejector body in the shape of a through hole, a puncture portion is arranged on the top of the ejector body, a port is arranged on the top of the ejector body which is connected to the inside of the ejector body, and the ejector body also comprises a decontamination mechanism which is used to remove dirt on the top of the ejector body.
[0007] Furthermore, the puncturing portion is a sharp spike and is arranged in a circle with the hole as the center.
[0008] Furthermore, the decontamination mechanism includes a negative pressure pipeline, a positive pressure pipeline connected and a rotary one-way valve. The negative pressure pipeline and the positive pressure pipeline are connected to the ejector body, and a rotary one-way valve is arranged between the negative pressure pipeline, the positive pressure pipeline and the ejector body.
[0009] Furthermore, flow detection devices are provided in the negative pressure pipeline and the positive pressure pipeline.
[0010] The beneficial effects of the utility model are as follows:
[0011] 1. There are holes on the top of the ejector pin, which can form positive and negative pressure to absorb and clean the residual glue on the top of the ejector pin, preventing the residual glue from adhering to the grains and being taken away, effectively solving the problem of residual glue on the ejector pin and improving product quality.
[0012] 2. The ejector device can detect whether there are any foreign objects remaining. It can judge the remaining foreign objects through the gas flow rate and prompt that further manual cleaning or replacement is required. BRIEF DESCRIPTION OF THE DRAWINGS

[0017] In order to make the purpose, technical scheme and advantages of the embodiments of the utility model clearer, the technical scheme in the embodiments of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model. Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Generally, the components of the embodiments of the utility model described and shown in the drawings here can be arranged and designed in various different configurations.
[0018] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the present invention to be protected, but merely represents selected embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.
[0019] It should be noted that similar reference numerals and letters represent similar items in the following drawings, so once an item is defined in one drawing, it does not need to be further defined and explained in the subsequent drawings. In addition, the terms "first", "second", etc. are only used to distinguish the description and cannot be understood as indicating or implying relative importance.
[0020] In the description of the embodiments of the present invention, it should be noted that the terms "inside", "outside", "upper", etc. indicate orientations or positional relationships based on the orientations or positional relationships shown in the accompanying drawings, or are the orientations or positional relationships in which the utility model product is usually placed when in use. They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.
[0021] like Figure 1-3As shown, a novel ejector device of a sorting machine comprises an ejector body 2 in the shape of a through hole, a puncture portion 3 is arranged on the top of the ejector body 2, a device is arranged on the top of the ejector body 2 which is connected to the inside of the ejector body 2, a decontamination mechanism is arranged at the end of the ejector body 2, and the puncture portion 3 is a sharp object and is arranged in a circle with the hole 4 as the center;
[0022] In this embodiment, during the sorting process, a normal ejector pin may accumulate a certain amount of blue film residual glue on the top of the ejector pin due to repeated piercing of the blue film. Then, when the die is ejected by the ejector pin and grabbed by the nozzle, the blue film on the top of the ejector pin may adhere to the back of the die, and finally form an abnormal arrangement on the blue film of the bin sheet. However, the new ejector pin body 2 has a hole 4 on the top, which can form positive and negative pressure to adsorb and clean the residual glue on the top of the ejector pin, so as to prevent the residual glue from adhering to the die and being taken away, thereby effectively solving the problem of residual glue on the sorting ejector pin and improving product quality.
[0023] Specifically, the decontamination mechanism includes a negative pressure pipeline, a positive pressure pipeline connected and a rotary one-way valve 7, the negative pressure pipeline and the positive pressure pipeline are connected to the ejector body 2, and a rotary one-way valve 7 is provided between the negative pressure pipeline and the positive pressure pipeline and the ejector body 2;
[0024] In this embodiment, when the ejector pin ejects the die, negative pressure is formed (when the ejector pin rises, the synchronous rotary motor drives the rotary valve interface to face the negative pressure pipe 6, forming negative pressure inside the ejector pin). If blue film adhesive residue is generated during the process of ejecting the die, it can be effectively adsorbed on the ejector pin, thereby preventing the blue film adhesive residue from adhering to the die and being taken away;
[0025] After the crystal grain is caught by the nozzle, the top of the ejector pin is switched to positive pressure (when the ejector pin descends after the nozzle catches the crystal grain, the synchronous rotating motor drives the rotating valve interface to face the positive pressure pipe 5, forming positive pressure inside the ejector pin), which can blow out the residual glue of the blue film and achieve the function of cleaning the top of the ejector pin.
[0026] Specifically, flow detection devices are provided in the negative pressure pipeline and the positive pressure pipeline.
[0027] In this embodiment, if the residual glue on the blue film is not cleaned thoroughly during the switching to positive pressure cleaning, it can be detected and identified by the flow rate. If the current flow rate value is lower than a certain range of the initial unobstructed state, it is determined to be blocked and not cleaned thoroughly.
[0028] The above description enables those skilled in the art to implement or use the present invention. Various modifications to these embodiments will be apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention will not be limited to the embodiments shown herein, but will conform to the widest scope consistent with the principles and novel features disclosed herein.
