[0027] In order to make the technical scheme in the embodiments of the present application clearer, the following will briefly introduce the drawings needed in the embodiment description. Obviously, the drawings in the following description are only some embodiments of the present application, and for those skilled in the art, other drawings can also be obtained without creative labor.

[0028] Figure 1 is a structural schematic diagram of a die bonding system provided by the embodiments of the present application, comprising a die bonding mechanism 1 and an airflow monitoring device (the whole is not shown in the figure) ; the airflow monitoring device comprises two airflow sensors 21, the die bonding mechanism 1 comprises a fixed support 11, and the airflow sensor 21 is installed on the fixed support 11. Figure 1

[0029] The die bonding mechanism 1 comprises a first air port and a second air port, the first air port and the second air port are opposite in position, and the two airflow sensors 21 are respectively installed on the first air port and the second air port. The first air port and the second air port are airflow open areas, that is, the face where the airflow sensor 21 is located in the die bonding mechanism 1 is without a baffle, and the other two side faces are provided with baffles.

[0030] ​The die bonding mechanism usually further comprises a die bonder main body and a fixing structure mounted on the die bonder main body for clamping the die expanding ring, the fixing structure comprises a bottom plate, a rectangular frame is arranged around the upper end of the bottom plate, and sliding rails are arranged around the rectangular frame, respectively, slidable clamping pieces are arranged on each two opposite sliding rails, respectively, the positions of the clamping pieces can be changed through an adjusting mechanism, and then the position of the die expanding ring can be adjusted.

[0031] The air flow sensor is a sensor for detecting and measuring air flow, and by detecting the pressure difference from the air flow, the speed and direction of the air flow can be calculated. Figure 2 As shown in Figure 2 The two air flow sensors 21 are respectively installed on the first air inlet and the second air inlet of the die bonding mechanism 1, and the first air inlet and the second air inlet are opposite to each other. For the die bonding mechanism 1, in the case that the wind direction of the external air source is single, one of the first air inlet and the second air inlet is usually an air inlet, and the other is an air outlet, Figure 2 That is, in the case that the wind direction of the external air source is single, Figure 2 The arrow in indicates the wind direction, and it can be seen that the air flow flows from one air inlet to the other air inlet. It should be noted that the flow of air flow generates wind, and in the present application, air flow monitoring is to detect the size (wind speed) and direction of air flow. For the die bonding mechanism, in the case that the wind direction of the external air source is complex, both the first air inlet and the second air inlet can be air inlets, and both can be air outlets.

[0032] It can be known that the two air flow sensors are arranged at the two air inlets of the die bonding mechanism, and have the following technical effects:

[0033] On the one hand, since the two air flow sensors are both installed on the die bonding mechanism and are very close to the die bonding mechanism, the air flow data near the die bonding mechanism can be accurately detected; the air flow direction data of the equipment can be viewed in all states of the equipment, and the change of the air flow direction of the equipment when the equipment is static and when the equipment is driven can be more comprehensively confirmed. When the equipment has air flow related quality problems, for example, foreign matter in the equipment cannot be discharged in time, or foreign matter adheres to the surface of the display panel during engineering operation in the die bonding mechanism, resulting in quality problems, data query and cause analysis can be performed to quickly confirm the measures for poor quality and improve the product yield.

[0034] On the other hand, the two air flow sensors are installed at different air inlets of the die bonding mechanism, and can accurately detect the air flow data of different air inlets, which is suitable for the case that there are many air flow sources (air sources) and the air flow direction is complex in the production workshop.

[0035] In an optional embodiment, as Figure 3An air flow sensor structure schematic diagram is shown, the air flow sensor 21 includes warning light 211, when the value of air flow exceeds the preset value threshold, the light color of the warning light 211 is the first color, when the value of air flow does not exceed the preset value threshold, the light color of the warning light 211 is the second color, exemplary, the first color is red, the second color is green, since the air flow sensor 21 is installed on the die bonding mechanism 1, thus also can in time prompt the staff who carries out operation at the die bonding mechanism 1 to handle the early warning situation, make the die bonding mechanism 1 work under the condition of meeting the air flow requirement.

[0036] Figure 4 The structure schematic diagram of the air flow monitoring device provided by the utility model embodiment is as shown in the drawing, Figure 4 The air flow monitoring device includes two air flow sensors 21, a repeater 22 and a monitoring terminal 23, the air flow sensors 21 are all in communication connection with the repeater 22, and the repeater 22 is in communication connection with the monitoring terminal 23.

[0037] Among them, the airflow sensor 21, the repeater 22 and the monitoring terminal 23 are in the same communication network, and the airflow sensor 21 is located on the solid crystal mechanism. In order to facilitate installation and setting, the airflow sensor 21 and the repeater 22 can communicate with each other by wireless communication, and the repeater 22 and the monitoring terminal 23 can communicate with each other by wireless or wired communication. The repeater 22 is a connection device working on the physical layer, suitable for the interconnection of two completely identical networks. Its main function is to expand the distance of network transmission by retransmitting or forwarding data signals. In this embodiment, the repeater 22 can forward the data of the airflow sensor 21 to the monitoring terminal 23. The monitoring terminal 23 is provided with a display and a memory, so that the monitoring terminal 23 can store the data of the airflow sensor 21, and the management personnel of the solid crystal mechanism can view the data of the airflow sensor 21 on the display to realize real-time monitoring of the airflow conditions around the solid crystal mechanism. For example, in an LED production workshop, the work between the production lines of each process is closely connected. In order to facilitate operations, the working areas of each process (crystal bonding, wire welding, glue dispensing, etc.) are usually interconnected. For the crystal bonding production line, the cleanliness requirements for the production environment are high, so it is necessary to monitor the airflow conditions around the crystal bonding equipment and determine whether the airflow conditions around the equipment meet the preset requirements. For example, the size of the airflow is required not to exceed the preset threshold, and / or the direction of the airflow is required to be a specified direction, for example, the direction of the airflow is required to flow from the crystal bonding area to the wire welding area. When the airflow conditions around the equipment do not meet the preset airflow requirements, it means that the crystal bonding production conditions are not met, and the airflow conditions can be adjusted. For example, a fan can be used to change the direction and size of the airflow, or by coordinating the process execution time (of other processes that are prone to airflow disturbances) to make the airflow conditions around the equipment not meet the preset airflow requirements.

[0038] In addition, before the airflow sensors are installed at different air outlet positions, the specific airflow direction can be determined by comparing the data of the two airflow sensors at the air outlets in relative positions, and the two airflow sensors can be calibrated with each other to improve the detection accuracy and airflow monitoring effect.

[0039] In an optional embodiment, if Figure 3 As shown in the schematic diagram of the airflow sensor structure, metal sheets 212 are provided on both sides of the airflow sensor 21 body, and mounting holes are provided on the metal sheets 212. The airflow sensor 21 is installed and fixed on the die-bonding mechanism through the mounting holes, so that the airflow sensor 21 can perform detection in a stable state.

[0040] In an optional embodiment, if Figure 3The air flow sensor structure diagram shows that the air flow sensor 21 comprises a warning light 211, when the value of the air flow exceeds a preset value threshold, the light color of the warning light 211 is a first color, when the value of the air flow does not exceed the preset value threshold, the light color of the warning light 211 is a second color, for example, the first color is red and the second color is green, since the air flow sensor 21 is installed on the die bonding mechanism, thus the staff who operates at the die bonding mechanism can be timely prompted to deal with the early warning situation, so that the die bonding mechanism works under the condition of meeting the air flow requirement.

[0041] In an optional embodiment, the side of the air flow sensor is provided with an arrow icon, the arrow icon is used to indicate the installation direction of the air flow sensor, the installation direction is the direction of the air flow which the user wants to detect, for example, the staff wants to detect the air flow size and direction from the bonding wire room to the die bonding room, then the arrow icon can be pointed to the direction of the bonding wire room, the setting of the arrow icon can help to correctly install the air flow sensor, and improve the accuracy of detecting the air flow direction and the air flow size.

[0042] In addition, before the air flow sensor is installed to different air outlet positions, the specific air flow direction can also be determined by comparing the data of two air flow sensors of the relative position air outlet, and the two air flow sensors can be mutually calibrated, so as to improve the detection precision and the air flow monitoring effect.

[0043] In an optional embodiment, as shown in FIG. 6, the air flow sensor 21 comprises a warning light 211, when the value of the air flow exceeds a preset value threshold, the light color of the warning light 211 is a first color, when the value of the air flow does not exceed the preset value threshold, the light color of the warning light 211 is a second color, for example, the first color is red and the second color is green, since the air flow sensor 21 is installed on the die bonding mechanism, thus the staff who operates at the die bonding mechanism can be timely prompted to deal with the early warning situation, so that the die bonding mechanism works under the condition of meeting the air flow requirement. Figure 4As shown in the structural schematic diagram of one kind of air flow monitoring device, the air flow monitoring device further comprises a repeater 22 and a monitoring terminal 23, the air flow sensor 21 is connected with the repeater 22 in communication, and the repeater 22 is connected with the monitoring terminal 23 in communication. Among them, the air flow sensor 21, the repeater 22 and the monitoring terminal 23 are in the same communication network. The repeater is a connection device working on the physical layer, which is suitable for the interconnection of two completely same networks, and the main function is to expand the network transmission distance by retransmitting or forwarding the data signal. Then in this embodiment, the repeater 22 can forward the data of the air flow sensor 21 to the monitoring terminal 23, and the monitoring terminal 23 is provided with a display and a memory, so that the monitoring terminal 23 can store the data of the air flow sensor 21, and the management personnel of the die bonding mechanism can view the data of the air flow sensor 21 at the display, realizing real-time monitoring of the air flow around the die bonding mechanism. For example, in the production workshop of LED type, the work between the production lines of each process is closely connected, in order to facilitate the work, the working areas (die bonding, wire bonding, dispensing area) of each process are usually interconnected, and the cleanliness of the production environment is required to be higher for the die bonding production line, so it is necessary to monitor the air flow around the die bonding equipment and judge whether the air flow around the equipment meets the preset requirements, for example, the size of the air flow cannot exceed the preset threshold, and / or the direction of the air flow is the specified direction, for example, the direction of the air flow is from the die bonding area to the wire bonding area, when the air flow around the equipment does not meet the preset air flow requirements, it means that the die bonding production conditions are not met, and the air flow condition can be adjusted, for example, the air flow direction and size are changed by using the fan, or the air flow condition around the equipment does not meet the preset air flow requirements by coordinating (other processes that are easy to produce air flow disturbance) process execution time.

[0044] In an alternative embodiment, as Figure 5 As shown in the structural schematic diagram of another air flow monitoring device, the air flow monitoring device further comprises a controller 24, the controller 24 is connected with the air flow sensor 21 and the repeater 22 respectively, and the air flow sensor 21 converts the inhaled air flow into an electric signal by measuring the inhaled air flow. The controller 24 is used for controlling and monitoring the working state (electric signal) of the air flow sensor 21, and transmitting the data of the air flow sensor 21 to the repeater 22, so that the repeater 22 can also transmit the data to the monitoring terminal 23.

[0045] In an alternative embodiment, the controller comprises a display screen, a communication state indicating lamp, an abnormal state indicating lamp and a working mode setting button.

[0046] For example, the controller comprises the following components / buttons:

[0047] (1) LCD: running data display part;

[0048] (2) Communication LED (COMM.): communication status indicator;

[0049] (3) Abnormal LED (ALARM): indicator when an abnormality occurs;

[0050] (4) SET button: setting mode and control data value input button;

[0051] (5) EXIT button: button for moving from the corresponding mode to the previous mode;

[0052] (6) UP button: control selection button within each mode;

[0053] (7) DOWN button: control selection button within each mode;

[0054] (8) LEFT button: control data value change button;

[0055] (9) RIGHT button: control data value change button;

[0056] (10) ALL: overall monitoring button;

[0057] It can be known that by operating the above-mentioned buttons, the working mode of the air flow sensor can be set or changed, which is convenient for the operator to operate and set, and at the same time, the sensing data of the air flow sensor can be clearly displayed.

[0058] For example, after the controller is set, it will display “+-” and “01 / 02”. “+” indicates that the air flow direction is correct, and “-” indicates that the air flow direction is opposite to the ideal air flow direction, i.e. the air flow direction is incorrect. 01 / 02 represents the ID of the air flow sensor. When setting, the ID of the air flow sensor installed in front of the die bonding mechanism is 01, and the ID of the air flow sensor installed behind the die bonding mechanism is 01. The value represents the air flow rate of the air flow sensor, which will be automatically converted into wind speed after uploading to the monitoring terminal. Air flow reversal will cause the direction to be “-”, which will trigger the alarm control, i.e. the warning light on the air flow sensor will emit light in the first color.

[0059] In an optional embodiment, as shown in Figure 1 or Figure 2 The installation height of the two air flow sensors is the same. Because the higher the height, the lower the air pressure, this can make the detection height of the air flow sensor the same, reduce the error of the two air flow sensors in environmental factors, i.e. reduce the detection error and improve the detection accuracy.

[0060] In an alternative embodiment, the die bonding mechanism comprises a fixed support, and the two airflow sensors are installed at the same or different angles relative to the fixed support. It is also an important advantage of setting the airflow sensors at different angles to adapt to different airflow direction changes. By using sensors at different angles, the complex airflow changes can be better coped with, and accurate data can be obtained under various airflow conditions.

[0061] In an alternative embodiment, as shown in Figure 1 The die bonding mechanism 1 comprises a workbench 12 for die bonding, and the airflow sensor 21 is installed at a position higher than the workbench 12. For example, the height of the workbench is 100 cm, and the installation height of the airflow sensor 21 is 125-130 cm. Since it is not appropriate to have an obstacle beside the airflow sensor 21, the height of the airflow sensor 21 can be appropriately increased when there is an obstacle, and the height can reach 170-180 cm.

[0062] In an alternative embodiment, as shown in Figure 1 The airflow sensor 21 is located above the midpoint of the horizontal direction of the workbench 12, i.e., at the horizontal center position of the entire air inlet position, so that the wind speed of the air inlet can be accurately detected.

[0063] It should be understood that the above-described various forms of processes can be reordered, added or deleted. For example, the steps described in the present application can be executed in parallel, sequentially or in different orders, as long as the desired results of the technical solutions of the present application can be achieved, and the present application does not limit this.

[0064] The above specific embodiments do not constitute a limitation on the protection scope of the present application. It should be understood by those skilled in the art that various modifications, combinations, sub-combinations and substitutions can be made according to design requirements and other factors. Any modification, equivalent substitution and improvement made within the spirit and principles of the present application shall be included in the protection scope of the present application.
