Abstract
Description
Technical Field
[0001] This utility model belongs to the technical field of electroplating equipment, and in particular relates to an electroplating monitoring device and electroplating equipment. Background Technology
[0002] During the production of circuit boards, an electroplating process is required. The principle of electroplating is to deposit a layer of metal on the circuit board to form circuits and a protective layer. In current technology, electroplating is usually carried out by dissolving copper balls in an electrolyte solution.
[0003] During the production of printed circuit boards (PCBs), the copper balls are dissolved and consumed. If the copper balls are not replenished in time, they will fall below the electrolyte level, resulting in poor uniformity in the copper plating process. Therefore, it is usually necessary to inspect the status of the copper balls in the titanium basket. However, manual inspection not only increases labor costs but also leads to missed inspections or untimely checks. Utility Model Content
[0004] To address the aforementioned issues, this invention proposes an electroplating monitoring device and electroplating equipment. By designing a swingable floating detection device, the device can automatically detect the consumption of copper balls, thus avoiding the problem of poor copper plating uniformity caused by untimely detection.
[0005] The objective of this utility model is achieved through the following technical solution:
[0006] In a first aspect, this utility model proposes an electroplating monitoring device, comprising:
[0007] The titanium basket contains an electrolyte and multiple copper balls;
[0008] The detection device includes a swing arm, a floating part, a support part, and a detection part. The floating part is fixed to one end of the swing arm and floats on the uppermost copper ball in the titanium basket. The detection part is located at the other end of the swing arm, and the support part is located in the middle of the swing arm. The position of the floating part changes due to the dissolution of the copper ball, causing the detection part to swing.
[0009] An electroplating monitoring device uses a titanium basket containing electrolyte and multiple copper balls. A detection device is installed within the basket, comprising a swing arm, a floating section, a support section, and a detection unit. The floating section is fixed to one end of the swing arm and floats on the uppermost copper ball in the basket. The detection unit is located at the other end of the swing arm, with the support section located in the middle of the swing arm. The dissolution of the copper balls causes the float to change position, thus oscillating the detection unit. By using the floating section on the uppermost copper ball, as the copper ball is consumed, the floating section moves downwards and lifts the detection unit at the other end. The position of the detection unit determines the current copper ball consumption, preventing poor copper plating uniformity caused by untimely detection of copper balls.
[0010] In some embodiments, the detection unit is provided with a first detection position and a second detection position; the second detection position is located above the first detection position; after the copper ball melts, the floating part provided on the copper ball descends, causing the detection unit to move from the first detection position to the second detection position.
[0011] By setting a first detection position and a second detection position, the movement of the floating part during production causes the position of the detection part to change, which can determine the position of the detection position and thus determine the current consumption of copper balls.
[0012] In some embodiments, the detection unit is provided with a first detection unit, a second detection unit, and a sensor; and the detection unit is also provided with a third detection position;
[0013] The first detection unit is located at one end of the swing arm, and the second detection unit is located at the third detection position. The second detection position is located adjacent to the third detection position. The first detection unit and the second detection unit are connected to both ends of the sensor so that when the first detection unit moves from the first detection position to the second detection position, the second detection unit and the first detection unit are connected to energize the sensor.
[0014] By setting the first detection unit at the second detection position, the first detection unit and the second detection unit can be connected to form a circuit, thereby energizing the sensor.
[0015] In some implementations, the first detection unit and the second detection unit are metal blocks.
[0016] By setting metal blocks in the first and second detection sections, a circuit can be formed when the first and second detection sections come into contact.
[0017] In some implementations, the sensor is a buzzer.
[0018] An alarm is triggered by a buzzer to promptly remind users to add copper balls.
[0019] In some embodiments, the detection device is further provided with a tank wall, on which a first platform is provided, and a support is provided on the first platform, such that the height of the support is set at the same height as the opening of the titanium basket.
[0020] The support part can be raised to the opening of the titanium basket by the groove wall, so that the floating part can swing according to the copper ball inside the titanium basket.
[0021] In some embodiments, the support includes a support base and a rotating shaft; the rotating shaft is located in the middle of the swing arm and rotates on the support base.
[0022] The support includes a support base and a rotating shaft, which enable the swing arm to rotate.
[0023] In some implementations, the floating part is a float.
[0024] By placing a float above a copper ball, the copper ball can support the float and allow it to move.
[0025] In some embodiments, a titanium basket hanging lug is provided on one side of the basket opening.
[0026] Secondly, this utility model proposes an electroplating equipment, including an electroplating monitoring device, an electroplating power supply, an electroplating device, a filtering device, a display device, and a cleaning device according to any one of the first aspects; the electroplating device electroplats the circuit board, the filtering device filters impurities, the display device displays alarm information, and the cleaning device cleans the circuit board before and after electroplating.
[0027] The beneficial effects of this utility model of an electroplating monitoring device and electroplating equipment are:
[0028] An electroplating monitoring device uses a titanium basket containing electrolyte and multiple copper balls. A detection device is installed within the basket, comprising a swing arm, a floating section, a support section, and a detection unit. The floating section is fixed to one end of the swing arm and floats on the uppermost copper ball in the basket. The detection unit is located at the other end of the swing arm, with the support section located in the middle of the swing arm. The dissolution of the copper balls causes the float to change position, thus oscillating the detection unit. By using the floating section on the uppermost copper ball, as the copper ball is consumed, the floating section moves downwards and lifts the detection unit at the other end. The position of the detection unit determines the current copper ball consumption, preventing poor copper plating uniformity caused by untimely detection of copper balls. Attached Figure Description

[0045] Example 1:
[0046] like Figure 1 As shown, this utility model proposes an electroplating monitoring device, comprising:
[0047] The titanium basket 1 is equipped with an electrolyte and multiple copper balls 11;
[0048] The detection device 2 is provided with a swing arm 21, a floating part 22, a support part 23, and a detection part 24. The floating part 22 is fixed to one end of the swing arm 21 and floats on the uppermost copper ball 11 in the titanium basket 1. The detection part 24 is provided at the other end of the swing arm 21, and the support part 23 is provided in the middle of the swing arm 21. The position of the floating part 22 changes due to the dissolution of the copper ball 11, so that the detection part 24 swings.
[0049] Specifically, the titanium basket 1 contains an electrolyte solution for dissolving copper balls 11. Multiple copper balls 11 are arranged such that the highest point of each ball is above the opening of the basket. A detection device 2 is also provided. This device uses a lever mechanism; when a copper ball 11 is consumed, the floating part 22 at the top of the ball 11 decreases, causing the detection part 24 at the other end of the swing arm 21 to rise. By detecting changes in height, or by triggering a condition based on these changes, the consumption of the copper ball 11 can be detected in a timely manner. The detection part 24 can be a position sensor, detecting consumption by measuring the current height of the sensor relative to the ground. Alternatively, it can be a shielding part, with an infrared sensor located near the detection part 24 on the swing arm 21. When the detection part 24 moves to the infrared sensor, the sensor emits a detection signal. A gyroscope can also be used to determine the current rotation position and thus the degree of consumption. Another method is to raise the detection part 24 to a certain position and then activate a switch to trigger a signal. The principle of the above method is based on the lever principle. After the copper ball 11 is consumed, it drives the float to move, thereby changing the position of the detection unit 24. The consumption of the copper ball 11 is detected by the change in position.
[0050] An electroplating monitoring device includes a titanium basket 1 containing an electrolyte and multiple copper balls 11. A detection device 2 is also installed in the basket 1, comprising a swing arm 21, a floating part 22, a support part 23, and a detection part 24. The floating part 22 is fixed to one end of the swing arm 21 and floats on the uppermost copper ball 11 in the basket 1. The detection part 24 is located at the other end of the swing arm 21, with the support part 23 located in the middle of the swing arm 21. The dissolution of the copper balls 11 causes the float to change position, thus causing the detection part 24 to swing. By installing the floating part 22 on the uppermost copper ball 11, when the copper ball 11 is consumed, the floating part 22 moves downward and lifts the detection part 24 at the other end. The position of the detection part 24 determines the current consumption status of the copper ball 11, avoiding the problem of poor copper plating uniformity caused by untimely detection of the copper balls 11.
[0051] Example 2:
[0052] like Figures 2-4 As shown, this embodiment further explains and optimizes the structure proposed in Embodiment 1, with the following differences:
[0053] In some embodiments, the detection unit 24 is provided with a first detection position 243 and a second detection position 244; the second detection position 244 is located above the first detection position 243; after the copper ball 11 is dissolved, the floating part 22 provided on the copper ball 11 descends, causing the detection unit 24 to move from the first detection position 243 to the second detection position 244.
[0054] Specifically, by setting two detection positions, under normal conditions, the detection unit 24 is set at the first detection position 243. After the copper ball 11 is gradually consumed, the detection unit 24 rises to the second detection position 244. By detecting whether the detection unit 24 is present at the second detection position 244, the consumption of the copper ball 11 can be determined.
[0055] By setting the first detection position 243 and the second detection position 244, the movement of the floating part 22 during production causes the position of the detection part 24 to change, which can determine the position of the detection position and thus determine the current consumption status of the copper ball 11.
[0056] In some embodiments, the detection unit 24 is provided with a first detection unit 241, a second detection unit 242 and a sensor; and the detection unit 24 is also provided with a third detection position 245;
[0057] The first detection unit 241 is disposed on one end of the swing arm 21, the second detection unit 242 is disposed on the third detection position 245, and the second detection position 244 is disposed adjacent to the third detection position 245. The first detection unit 241 and the second detection unit 242 are connected to both ends of the sensor so that when the first detection unit 241 moves from the first detection position 243 to the second detection position 244, the second detection unit 242 and the first detection unit 241 are connected to energize the sensor.
[0058] Specifically, two detection units 24 are configured. The first detection unit 241 is fixed on the swing arm 21, and the other is located at the third detection position 245. The third detection position 245 is adjacent to the second detection position 244. When the copper ball 11 is consumed, the first detection unit 241 moves to the second detection position 244 and approaches the second detection unit 242. By detecting the change in distance between them, the copper ball 11 can be identified. Furthermore, a formula can be used to determine the rate and percentage of copper ball 11 consumption, thus providing a quantitative indicator of copper ball 11 consumption. Simultaneously, the system can also detect whether the first detection unit 241 and the second detection unit 242 are in contact. A trigger signal is generated upon contact, enabling timely and accurate external alarms. In this embodiment, a signal circuit is set between the first detection unit 241 and the second detection unit 242, and a sensor is set in the signal circuit. The first detection unit 241 and the second detection unit 242 can be used as switches. Under normal conditions, they are disconnected, and when the alarm value is consumed, they are closed and an alarm signal is sent out through the sensor.
[0059] By setting the first detection unit 241 on the second detection position 244, the first detection unit 241 and the second detection unit 242 can be connected to form a circuit, thereby energizing the sensor.
[0060] In some embodiments, the first detection unit 241 and the second detection unit 242 are metal blocks.
[0061] The metal allows the aforementioned circuit to be switched on and off via the first detection unit 241 and the second detection unit 242.
[0062] By setting metal blocks in the first detection unit 241 and the second detection unit 242, a circuit can be formed when the first detection unit 241 and the second detection unit 242 come into contact.
[0063] In some embodiments, the sensor is a buzzer 246.
[0064] An alarm is triggered by buzzer 246, prompting timely reminders to add copper ball 11.
[0065] In some embodiments, the detection device 2 is further provided with a tank wall 3, on which a first platform 31 is provided, and a support 23 is provided on the first platform 31, such that the height of the support 23 is set at the same height as the opening of the titanium basket 1.
[0066] Specifically, the tank wall 3 is set on one side of the titanium basket 1, and a first platform 31 is set above the tank wall 3. The support part 23 is set on the first platform 31 so that the detection device 2 is set at the opening of the titanium basket 1, avoiding the floating part 22 from not being able to be set at the top of the copper ball 11 due to being too high, and also avoiding the floating part 22 from not being able to swing due to being too low.
[0067] The support 23 can be raised to the opening of the titanium basket 1 by the groove wall 3, so that the floating part 22 can swing according to the copper ball 11 inside the titanium basket 1.
[0068] In some embodiments, the support 23 includes a support base and a rotating shaft; the rotating shaft is disposed in the middle of the swing arm 21 and rotates on the support base.
[0069] Specifically, the support base can be fixed on both sides and have a rotation channel in the middle, and the support base is provided with rotation holes. The rotating shaft is set in the rotation holes on both sides and rotates. A through hole is provided in the middle of the rotating shaft so that the swing arm 21 is set in the through hole and the rotating shaft is fixed in the middle of the swing arm 21, so as to realize the rotation of the swing arm 21 on the support base.
[0070] The support part 23 includes a support base and a rotating shaft, through which the swing arm 21 can rotate.
[0071] In some embodiments, the floating part 22 is a float.
[0072] Optionally, a float plate can be used. It should be noted that the weight of the selected floating part 22 is greater than the weight of the detection part 24.
[0073] By placing a float above the copper ball 11, the copper ball 11 can support the float and move it.
[0074] In some embodiments, a hanging ear for the titanium basket 1 is provided on one side of the basket opening.
[0075] Example 3:
[0076] like Figure 5 As shown, this embodiment proposes an electroplating device, including an electroplating monitoring device, an electroplating power supply, an electroplating device, a filtering device, a display device, and a cleaning device, as described in either Embodiment 1 or Embodiment 2. The electroplating device electroplats the circuit board, the filtering device filters impurities, the display device displays alarm information, and the cleaning device cleans the circuit board before and after electroplating.
[0077] Specifically, the circuit board is electroplated using an electroplating device, the consumption of copper balls 11 in the titanium basket 1 is monitored by an electroplating monitoring device, and a host computer is set in the display device. When the detection unit 24 swings to the warning position, an alarm is triggered by the host computer. The required DC power is provided by the electroplating power supply, impurities and particles are filtered by a filter device, and the circuit board is cleaned before and after electroplating by a cleaning device.
