Description

Technical Field

[0001] The utility model belongs to the technical field of wire bonding machines and related equipment, and particularly relates to a height detection device for controlling the service life of a spark rod. Background Technique

[0002] Wire bonding machines include gold wire machines, aluminum wire machines, and ultrasonic wire bonding machines. Generally, for gold wire machines, the most common ASM copper wire welding machines in the market are the KS CONNX machines with very high efficiency. For aluminum wire machines, the most popular ones in the market are the OE machines. The spark rod of the wire bonding machine is specifically used for high-voltage discharge in the LED wire bonding machine to melt and burn balls of media such as gold wire, copper wire, and alloy wire. This process is also called the EFO effect. In the LED production process, the welding of the gold wire cannot do without high-voltage discharge to achieve ball burning. In the operation process, in addition to the stability of the voltage, the quality of the spark rod has a direct impact on the quality of ball burning. Therefore, after the spark rod is used for a period of time, it is necessary to detect its wear degree through a height detection device to avoid poor ball burning in the wire bonding process, which may cause problems such as splitting knife marks or crater abnormalities.

[0003] However, it still has the following disadvantages in actual use:

[0004] Most of the existing height detection devices for controlling the service life of spark rods detect the used spark rods by comparing them with physical spark rods during use. In this way, during detection, the staff can only detect a single spark rod, resulting in low detection efficiency of the spark rod.

[0005] 2. When the existing height detection device for controlling the service life of spark rods is detecting, since the base of the spark rod is not horizontal, in order to ensure the horizontal and stable state of the bottom of the spark rod, the staff needs to stably hold the physical spark rod and the detected spark rod for a long time, which will affect the detection accuracy of the spark rod. Therefore, we provide a height detection device for controlling the service life of spark rods to solve the above problems. Content of the Utility Model

[0006] The purpose of the utility model is to provide a height detection device for controlling the service life of spark rods. By setting a conveying component, multiple spark rods can be quickly and continuously detected, improving the detection efficiency of the spark rods. And by using a pressing component, the stability of the spark rod to be detected can be improved, avoiding the poor stability of the spark rod to be detected and affecting the detection accuracy.

Detailed implementation manners

[0030] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0031] Example 1, please refer to Figures 1 to 4 , the present invention is a height detection device for controlling the life of a lighter rod, including a detection table 1, and a first support plate 104 installed at the front end of its upper surface, and second support plates 105 are symmetrically installed behind the first support plate 104. A conveyor assembly 2 is provided between the first support plate 104 and the second support plate 105; the conveyor assembly 2 includes a U-shaped frame 201 installed on the upper surface of the detection table 1, and a motor 202 installed on one side of the front end face of the U-shaped frame 201.

[0032] Specifically, a fixed seat 101 is installed on one side of the rear of the upper surface of the detection table 1, a base 102 is installed on the upper surface of the fixed seat 101, a lighter rod is installed on the upper surface of the base 102, a height sensor 103 is installed on the front end face of the fixed seat 101, a pushing plate 103a is installed at the front end of the height sensor 103, the output shaft of the motor 202 is connected to the rotating shaft 202a through a coupling, the other end of the rotating shaft 202a penetrates through the bearing on the front end face of the U-shaped frame 201 and is connected through the bearing on the inner wall of the U-shaped frame 201. A driving roller 204 is installed on the outer wall of the rotating shaft 202a, a driving sprocket 203 is sleeved on the outer wall of the rotating shaft 202a, auxiliary rollers 206 are installed in an array along the horizontal direction on one side of the driving roller 204, a driven sprocket 205 is installed at the front end of the rotating rod of the auxiliary roller 206, and the outer walls of the driving sprocket 203 and the driven sprocket 205 are connected by a chain.

[0033] Furthermore, the first support plate 104 and the second support plate 105 are identical in shape, structure, size, etc. The shapes of the first support plate 104 and the second support plate 105 are both L-shaped, and they are symmetrically arranged. The dial plate 103a is made of a flexible material, which can limit the ignition rod to be detected, and at the same time will not affect the movement of the ignition rod. The outer walls of the driving sprocket 203 and multiple driven sprockets 205 are connected by a chain to play a role in connecting and transmitting. The height sensor 103 is a high-precision sensor detection device, and the detection unit is um. This is the prior art, and the structure, principle, etc. will not be elaborated too much. When detecting the ignition rod, it is controlled by an external controller and realizes automatic comparison detection. After the height sensor 103 detects, the data of the ignition rod that does not meet the standard is transmitted to the external controller, the device operation will be automatically stopped and an alarm will be issued, and the ignition rod that does not meet the standard will be removed, which can improve the detection accuracy and detection efficiency.

[0034] The operation process of this embodiment is as follows: Place the base 102 of the ignition rod to be detected on the surfaces of the driving roller 204 and the auxiliary roller 206, and after pressing the base 102 of the ignition rod to be detected by the pressing component 3, start the motor 202. The output shaft of the motor 202 rotates to drive the rotating shaft 202a to rotate through a coupling. The rotation of the rotating shaft 202a will drive the driving roller 204 and the driving sprocket 203 on its outer wall to rotate. Among them, the outer walls of the driving sprocket 203 and multiple driven sprockets 205 are connected by a chain to play a role in transmission. Therefore, when the driving sprocket 203 rotates, it will drive multiple driven sprockets 205 to rotate synchronously, so that the auxiliary roller 206 and the driving roller 204 rotate synchronously, and then the base 102 of the ignition rod to be detected on the surface can be conveyed. Then, the ignition rod to be detected can be transported to a new ignition rod for comparison installed on the fixed seat 101. Then, use the height sensor 103 to compare whether the ignition rod to be detected is worn. After the detection, the ignition rod is continuously conveyed, and the flexible dial plate 103a can push it out, and at the same time, the ignition rods to be detected behind can be conveyed for detection in turn, so that multiple ignition rods can be quickly and continuously detected, improving the detection efficiency of the ignition rod.

[0035] Embodiment 2, please refer to Figure 2 and Figure 5 , on the basis of Embodiment 1, different from the first embodiment: A pressing component 3 is provided. The pressing component 3 includes a pressing plate 301 arranged with a gap inside the first support plate 104 and the second support plate 105, and a connecting rod 302 arranged in an array along the horizontal direction on the upper surface of the pressing plate 301, which solves the problem that when the existing height detection device for controlling the service life of the ignition rod is detecting, since the base of the ignition rod is not horizontal, in order to ensure the horizontal and stability of the bottom of the ignition rod, it is necessary for the staff to stably hold the physical ignition rod and the detection ignition rod for a long time, which will affect the detection accuracy of the ignition rod.

[0036] Specifically, the top end of the connecting rod 302 passes through the through hole on the first support plate 104 or the second support plate 105 and is connected to the limiting plate 304. A spring 303 is sleeved on the outer wall of the connecting rod 302. The spring 303 is located between the pressing plate 301 and the adjacent first support plate 104 or second support plate 105. The two ends of the pressing plate 301 are arc-shaped.

[0037] Furthermore, connecting the pressing plate 301 and the limiting plate 304 through the connecting rod 302 plays a role in connecting and transmitting power. Under the elastic performance of the spring 303, the pressing plate 301 can be driven to move.

[0038] The operation process of this embodiment is as follows: When it is necessary to place the igniting rod to be detected on the surfaces of the driving roller 204 and the auxiliary roller 206, the base 102 of the igniting rod is pushed between the pressing plate 301 and the driving roller 204. At this time, the base 102 of the igniting rod applies a force to the pressing plate 301, and the pressing plate 301 moves upward under the force. Since the surface of the pressing plate 301 is connected to the limiting plate 304 through the connecting rod 302, when the pressing plate 301 moves upward under the force, it will push the limiting plate 304 upward through the connecting rod 302 and compress the spring 303. Then, the base 102 of the igniting rod can be inserted between the pressing plate 301 and the driving roller 204. After the base 102 of the igniting rod is inserted, under the elastic performance of the spring 303, the pressing plate 301 can be bounced downward and a force is applied to the pressing plate 301, so that the pressing plate 301 can be tightly pressed on the surface of the pressing plate 301, thereby pressing down the base 102 of the igniting rod to be detected, and thus improving the stability of the igniting rod to be detected and avoiding the poor stability of the igniting rod to be detected from affecting the detection accuracy.
