Description

Technical Field

[0001] This utility model relates to the technical field of lead frame manufacturing equipment, specifically to an automatic electroplating production line device for lead frames. Background Art

[0002] Leadframes are a key component in semiconductor packaging, primarily used to connect internal circuitry to external circuit boards. During the manufacturing process, leadframes undergo electroplating to improve conductivity, enhance solderability, and provide corrosion protection.

[0003] In many existing electroplating production lines, it is necessary to manually identify the position and distance of the lead frame and operate the electroplating switch. This method is labor-intensive and inefficient. In addition, manual control carries a significant risk of operational errors, which may lead to unsatisfactory electroplating results and thus affect the product quality of the lead frame.

[0004] In summary, this utility model provides an automatic electroplating production line device for lead frames. Utility Model Content

[0005] The purpose of this utility model is to provide an automatic electroplating production line device for lead frames, so as to solve the problems mentioned in the background art, that existing electroplating production line devices require manual identification of the position and distance of the lead frames and manual operation of the electroplating switch, which leads to high labor costs, low work efficiency and unsatisfactory electroplating results.

[0006] This utility model is achieved using the following technical solution:

[0007] An automatic electroplating production line device for lead frames includes a conveying mechanism, a control mechanism, an automatic detection mechanism, and an electroplating mechanism. The automatic detection mechanism and the electroplating mechanism are respectively communicatively connected to the control mechanism. The automatic detection mechanism is located above or on both sides of the conveying mechanism. The conveying mechanism passes through the electroplating mechanism, and the electroplating mechanism is located behind the automatic detection mechanism along the conveying direction of the conveying mechanism.

[0008] The automatic electroplating production line device for lead frames provided by this utility model uses a conveying mechanism to transport the lead frames and an automatic detection mechanism to automatically detect the position of the lead frames. Once the automatic detection mechanism detects the lead frames, it transmits a signal to the control mechanism, which then controls the electroplating mechanism to start and stop after a set delay time. This achieves automatic control over the start and stop time and duration of electroplating, enabling accurate and efficient electroplating of the lead frames while freeing up manpower. The set delay time is obtained from multiple actual test data, and technicians can adjust it accordingly based on factors such as the conveying speed and the length of the lead frames.

[0009] Furthermore, the automatic detection mechanism includes a photoelectric sensor that detects the lead frame on the conveying mechanism. When the lead frame passes the photoelectric sensor under the conveying mechanism, the light beam emitted by the photoelectric sensor is reflected by the lead frame. The receiver of the photoelectric sensor (such as a photodiode or phototransistor) receives the changed light signal and converts it into a corresponding electrical signal, which is then sent to the control mechanism. This enables automatic detection of the lead frame's position.

[0010] Furthermore, the device also includes a vision inspection mechanism, which is communicatively connected to the control mechanism. The vision inspection mechanism is located at the electroplating mechanism and inspects the lead frame on the conveying mechanism. By incorporating the vision inspection mechanism, the electroplating process can be monitored in real time. If an electroplating abnormality is detected (e.g., abnormal plating thickness or abnormal plating area size), the control mechanism will immediately stop the electroplating process to prevent further escalation of the abnormality and facilitate inspection and handling by operators.

[0011] Furthermore, the device also includes an alarm mechanism, which is communicatively connected to the control mechanism. When the visual inspection mechanism detects an electroplating abnormality, in addition to controlling the electroplating mechanism to stop electroplating in a timely manner, the control mechanism can also control the alarm mechanism to sound an alarm, thereby reminding the operators to conduct timely inspection and handling.

[0012] Furthermore, the control mechanism includes a main body and operation keys and an operation panel mounted on the main body. The main body contains a controller. In actual use, the device can be started and stopped using the operation keys, and relevant settings and information can be viewed using the operation panel.

[0013] Furthermore, the number of automatic detection mechanisms and electroplating mechanisms is the same, and these mechanisms are spaced apart. In practical applications, due to process requirements, it may be necessary to perform multiple electroplating operations with different parameters on each lead frame. In this case, more than one set of automatic detection mechanisms and electroplating mechanisms can be set, but they need to be spaced apart so that each electroplating mechanism is linked by an automatic detection mechanism. This allows for individual control of each electroplating mechanism, resulting in more precise control.

[0014] Furthermore, each of the electroplating mechanisms includes one or more electroplating tanks. In practical applications, an appropriate number of electroplating tanks can be set in each electroplating mechanism according to the actual situation.

[0015] The beneficial effects achieved by this utility model are:

[0016] An automated electroplating production line device for lead frames is provided. By incorporating a conveying mechanism, a control mechanism, an automatic detection mechanism, and an electroplating mechanism, the device can automatically detect the position of the lead frames and coordinate with the electroplating mechanism to start and stop electroplating at appropriate times. Compared to existing technologies that require manual identification of the lead frame's position and distance and manual operation of the electroplating switch, this invention achieves automatic control over the electroplating start / stop time and electroplating duration, thereby eliminating manual operation, significantly saving labor costs, improving production efficiency, and effectively avoiding human error, thus ensuring the electroplating effect on the lead frames.

[0021] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0022] Example 1

[0023] This embodiment provides an automated electroplating production line device for lead frames. Please refer to [link / reference]. Figures 1 to 3 The device includes a conveying mechanism, a control mechanism 3, an automatic detection mechanism 1, an electroplating mechanism 2, a visual inspection mechanism, and an alarm mechanism. The automatic detection mechanism 1, electroplating mechanism 2, visual inspection mechanism, and alarm mechanism are all communicatively connected to the control mechanism 3. The automatic detection mechanism 1 is positioned above the conveying mechanism, which passes through the electroplating mechanism 2. The electroplating mechanism 2 is positioned behind the automatic detection mechanism 1 along the conveying direction of the conveying mechanism. Specifically:

[0024] The automatic detection mechanism 1 includes a photoelectric sensor 9, which detects the lead frame 10 on the conveying mechanism; the visual detection mechanism is located at the electroplating mechanism 2, and detects the lead frame 10 on the conveying mechanism; the alarm mechanism is located in a place easily noticed by the operator, and in this embodiment, the alarm mechanism is an audible and visual alarm; the control mechanism 3 includes a main body and operation keys 4 and an operation panel 5 located on the main body. The main body has a controller inside, and in this embodiment, the control mechanism 3 is also connected to the operator's mobile phone.

[0025] In this embodiment, the conveying mechanism includes several conveying shafts 6 (in other embodiments, a suitable structure can be flexibly selected as the conveying mechanism according to the actual situation, such as a conveyor belt, etc., and this utility model does not make any special limitation on this), and also includes several limiting structures. The limiting structure includes a limiting plate 7 with size markings. A strip hole 11 is opened on each side of the limiting plate 7. A limiting block 8 is tightened in each of the two strip holes 11 by screws. A lead wire frame 10 is located between the two limiting blocks 8.

[0026] In this embodiment, the number of automatic detection mechanisms 1 and electroplating mechanisms 2 is the same and there are multiple automatic detection mechanisms 1 and electroplating mechanisms 2. The multiple automatic detection mechanisms 1 and electroplating mechanisms 2 are arranged at intervals. Each electroplating mechanism 2 includes three electroplating tanks, and the electroplating parameters of each electroplating tank are different.

[0027] Based on the above structure, the working principle of this embodiment is as follows:

[0028] This automated electroplating production line for lead frames uses a conveying mechanism to transport the lead frames 10. An automatic detection mechanism 1 automatically detects the position of the lead frames 10. Once the automatic detection mechanism 1 detects the lead frames 10, it transmits a signal to the control mechanism 3. The control mechanism 3 then controls the electroplating mechanism 2 to open and close after a set delay time. Specifically:

[0029] When the lead frame 10 passes the photoelectric sensor 9 under the transmission of the transmission shaft 6, the light beam emitted by the photoelectric sensor 9 will be reflected by the lead frame 10. The receiver of the photoelectric sensor 9 (such as a photodiode or phototransistor) will receive the changed light signal and convert it into a corresponding electrical signal and send it to the control mechanism 3, thereby realizing the automatic detection of the position of the lead frame 10.

[0030] By setting up a visual inspection mechanism, the electroplating process can be monitored in real time. If an electroplating abnormality is detected (such as abnormal plating thickness or abnormal plating area size), the control mechanism 3 will control the electroplating mechanism 2 to stop electroplating in a timely manner to prevent the abnormality from escalating further and to facilitate inspection and handling by the operators. In addition, in this embodiment, when the photoelectric sensor 9 does not detect the lead frame 10 within a specific time, the control mechanism 3 will also trigger the electroplating mechanism 2 to stop operation. When the above situations occur, in addition to controlling the electroplating mechanism 2 to stop electroplating in a timely manner, the control mechanism 3 can also control the alarm mechanism to sound an alarm and send the alarm information to the operator's mobile phone, thereby reminding the operator to check and handle the situation in a timely manner. In actual use, the operator can start and stop the device through the operation key 4 and set relevant matters and view information through the operation panel 5.

[0031] In summary, by setting up a conveying mechanism, a control mechanism 3, an automatic detection mechanism 1, and an electroplating mechanism 2, the automatic electroplating production line device for lead frames provided in this embodiment can automatically detect the position of the lead frame 10 and link the electroplating mechanism 2 to start and stop electroplating at appropriate times. Based on this, manual operation is eliminated, thereby greatly saving labor costs and improving production efficiency. Furthermore, it effectively avoids human error, thus ensuring the electroplating effect on the lead frame 10.

[0032] It should be noted that the parts not described in detail or in detail in the above solution, such as the specific structure and principle of the electroplating tank, the program algorithm used by the control mechanism 3, and the specific structure of the vision inspection mechanism, are all existing technologies and are not improvements made by this utility model to the existing technology, nor are they within the protection scope of this utility model's technical solution. Therefore, they will not be elaborated on in this article.

[0033] Of course, the above description is only a preferred embodiment of this utility model and should not be considered as limiting the scope of the embodiments of this utility model. This utility model is not limited to the above examples, and all equivalent changes and improvements made by those skilled in the art within the scope of this utility model should be included in the patent coverage of this utility model.
