Abstract
Description
Technical Field
[0001] The utility model relates to a soldering flux containing device, in particular to a soldering flux containing device for improving flatness. Background Art
[0002] The description in this section merely provides background information related to the disclosure of the present utility model and does not constitute prior art.
[0003] In the semiconductor production process, materials generally need to be pretreated before soldering. Flux removes oxides or other contaminants that may be present on the material surface, allowing the material to flow better and adhere firmly to the soldering point, thereby forming a better electrical connection. A tray is typically used to hold the flux. When soldering is required, the material is removed in a certain manner and brought into contact with the flux in the tray, evenly coating the surface with flux to facilitate the next soldering step.
[0004] In the prior art, the bottom of a general tray is connected to other fixing devices through structures such as slots. However, during the installation process, especially when the operator is manually installing the tray, the tray is very likely to become unstable, which in turn causes abnormal flatness of the flux on the tray, making it impossible for the material to be welded to effectively and fully absorb the flux, thereby affecting the final welding effect.
[0005] Currently, there is no flux holding device for improving planarity that can solve the above problems. Utility Model Content
[0006] The purpose of the utility model is to provide a flux holding device for improving flatness. An adsorption mechanism can be provided on a fixed seat to make the installation of the tray more stable, and a sensor can be provided to facilitate real-time monitoring of the flatness of the tray.
[0007] In order to achieve the above-mentioned object, the present invention discloses the following flux holding device for improving flatness, which is used to hold flux; the flux holding device for improving flatness comprises:
[0008] A tray having a top surface and a bottom surface opposite to each other, the top surface of the tray having a concave groove, the soldering flux being filled in the groove, and the bottom surface of the tray including a positioning pin;
[0009] A fixing base, wherein the top surface of the fixing base includes a positioning hole, the shape of the positioning hole matches the positioning pin, so that the tray can be detachably mounted on the fixing base;
[0010] The fixing seat further includes an adsorption mechanism, which is arranged to avoid the position of the positioning hole and is arranged toward the direction of the tray;
[0011] The flux holding device for improving flatness also includes a sensor, a control center and a calibrator. The sensor and the calibrator are respectively connected to the control center signal. The sensor is installed on the fixed seat and the sensor is set in the direction of the tray. The sensor is used to identify the presence of the tray. Whenever the tray is placed back on the fixed seat, the control center is used to receive the detection signal of the sensor and drive the calibrator to send a control signal.
[0012] Furthermore, the adsorption mechanism is configured as a magnet, and the tray is configured as a magnetic material that can be adsorbed by the magnet.
[0013] Furthermore, the number of the adsorption mechanisms is four, and the four adsorption mechanisms are respectively arranged near the four corners of the tray.
[0014] Furthermore, the number of the positioning pins is two, the two positioning pins are arranged on the center line of the tray, and the length of each positioning pin from the edge of the tray is equal.
[0015] Furthermore, one of the positioning pins is configured to be cylindrical, and the other positioning pin is configured to be elliptical.
[0016] Furthermore, it also includes a scraper ring, which abuts against the top surface of the tray, and the flux is filled in the scraper ring. The tray and the scraper ring can perform relative repeated movement, so that after each relative movement, the flux in the scraper ring can be transferred to the groove of the tray.
[0017] Furthermore, the groove includes four reference points, which are respectively arranged at the four corners of the groove, wherein each of the reference points is equidistant from the edge of the groove. When the calibrator calibrates the flatness of the tray, it measures the height of the flux at the four reference points in turn.
[0018] By means of the above technical solution, the beneficial effects of the present invention are as follows:
[0019] 1. The flux holding device for improving flatness of the present invention can be provided with an adsorption mechanism on the fixing seat so that the adsorption mechanism plays an auxiliary positioning effect during each installation of the tray. With the cooperation of the positioning holes and the positioning pins, the installation success rate of the tray is higher, and the tray after installation is more stable and not easy to shake.
[0020] 2. The flux holding device for improving flatness of the present invention sets a sensor on the fixed seat to monitor whether the tray exists, and connects the sensor to the control center and the calibrator. Each time the operator takes and places the tray, the control center receives a signal and drives the calibrator to repeatedly calibrate the tray to avoid omissions and always keep the tray at a better flatness.

[0028] It should be understood that although terms such as "first," "second," and "third" may be used herein to describe various components or signals, these components or signals should not be limited by these terms. These terms are primarily used to distinguish one component from another, or one signal from another.

[0029] See Figure 1-2 , is a soldering flux holding device for improving flatness of this embodiment, used for holding soldering flux 100; wherein the soldering flux holding device for improving flatness includes:
[0030] The tray 1 has a top surface and a bottom surface facing each other. The top surface of the tray 1 has a concave groove filled with soldering flux 100. The bottom surface of the tray 1 includes a positioning pin 11.
[0031] The fixing base 2 includes a positioning hole 21 on the top surface thereof, the shape of the positioning hole 21 matches the positioning pin 11, so that the tray 1 can be detachably mounted on the fixing base 2;
[0032] The fixing base 2 further includes an adsorption mechanism 22 , which is arranged to avoid the position of the positioning hole 21 and is arranged toward the direction of the tray 1 ;
[0033] The flux holding device for improving flatness also includes a sensor 3, a control center and a calibrator 4. The sensor 3 and the calibrator 4 are respectively connected to the control center signal. The sensor 3 is installed on the fixed seat 2, and the sensor 3 is set in the direction of the tray 1. The sensor 3 is used to identify the presence of the tray 1. Whenever the tray 1 is placed back on the fixed seat 2, the control center receives the signal from the sensor 3 and drives the calibrator 4 to calibrate the flatness of the tray 1.
[0034] Regarding the above structure, when installing the fixing base 2, it is necessary to install the adsorption mechanism 22 and the sensor 3 at a preset position on the fixing base 2, and ensure that the height of the adsorption mechanism 22 and the sensor 3 does not protrude excessively from the top surface of the fixing base 2, so as to avoid that when the positioning pin 11 of the tray 1 is inserted into the positioning hole 21 of the fixing base 2, the adsorption mechanism 22, the sensor 3 and other structures arranged between the tray 1 and the fixing base 2 affect the complete docking of the positioning pin 11 with the positioning hole 21, thereby affecting the stability of the tray 1. However, the adsorption mechanism 22 still needs to be set within a range that can adsorb the tray 1 and generate an attractive force on the tray 1. Similarly, the sensor 3 also needs to be placed within a range that can effectively identify whether the tray 1 exists, so as to avoid misjudgment or failure to identify the tray 1.
[0035] Through the above structure, when the tray 1 needs to be placed on the fixing seat 2 on a daily basis, the operator only needs to move the positioning pin 11 of the tray 1 toward the positioning hole 21 of the fixing seat 2 and insert it into the positioning hole 21 so that the tray 1 is limited. During the insertion process, the tray 1 gradually approaches the fixing seat 2. When the tray 1 is close enough to the fixing seat 2, the tray 1 enters the suction range of the adsorption mechanism 22, so that the adsorption mechanism 22 of the fixing seat 2 has a certain guiding effect on the placement of the tray 1, avoiding the problem that the positioning pin 11 of the tray 1 and the positioning hole 21 of the fixing seat 2 are not completely combined together, resulting in the tray 1 not being in the same horizontal state as the fixing seat 2, and making it difficult for the flatness of the flux 100 in the groove of the tray 1 to meet the requirements. Through the suction guiding effect of the adsorption mechanism 22 of this embodiment, the success rate of the installation of the tray 1 is higher. At the same time, since the adsorption mechanism 22 of the fixing seat 2 still maintains a large suction force on the tray 1 after the tray 1 is fully installed on the fixing seat 2, the tray 1 in this embodiment is also relatively more stable during use.
[0036] At the same time, in this embodiment, with the help of the sensor 3 installed on the fixing base 2, a second checkpoint is formed to maintain the flatness of the flux 100 in compliance with the requirements. For maintenance purposes, when the operator removes the tray 1 from the fixing base 2, the sensor 3 can recognize that the tray 1 has disappeared. Then, when the operator reinstalls the tray 1 on the fixing base 2, the sensor 3 can recognize that the tray 1 exists and then transmit the information that the tray 1 has been put back to the control center. After receiving the information, the control center will issue an order such as Figure 2 The calibrator 4 shown calibrates the flatness of the tray 1 to avoid the situation where the newly installed tray 1 is unstable and the flatness does not meet the requirements, which affects the subsequent material coating operation of the flux 100.
[0037] Specifically, in this embodiment, the sensor 3 is configured as a metal-sensing proximity sensor, which senses the metal pallet 1 through the principle of electromagnetic induction. When the metal pallet 1 approaches the sensor 3, the intensity of the electromagnetic field will change, which has better stability and lower cost.
[0038] Furthermore, the adsorption mechanism 22 is configured as a magnet in the shape of a regular geometric disc, and the tray 1 is configured as a magnetic material that can be attracted by the magnet. Specifically, in this embodiment, the tray 1 is galvanized steel or other magnetic stainless steel. Furthermore, there are four magnets, each located near the four corners of the tray 1, to ensure a more balanced adsorption of the tray 1 and greater stability during installation.
[0039] Furthermore, there are two positioning pins 11, which are arranged on the centerline of the tray 1, and each positioning pin 11 is equidistant from the edge of the tray 1. By providing two positioning pins 11, the positioning of the tray 1 in terms of horizontal position and placement angle can be achieved with a relatively simple structure, thereby leaving more space at the bottom of the tray 1 for adsorption by the adsorption mechanism 22 or identification by the sensor 3. Specifically, one positioning pin 11 is configured as a cylinder, and the other positioning pin 11 is configured as an elliptical cylinder. The elliptical cylinder structure can further accurately determine the placement angle of the tray 1, thereby avoiding the occurrence of angular positioning deviation of the tray 1 when the two positioning pins 11 are simultaneously misaligned.
[0040] Furthermore, a scraper ring 5 is included, which is in contact with the top surface of the tray 1. The flux 100 is filled in the scraper ring 5. The tray 1 and the scraper ring 5 can perform relative and repeated movements, so that after each relative movement, the flux 100 in the scraper ring 5 can be transferred to the groove of the tray 1. Specifically, during use, the fixed seat 2 in this embodiment can drive the tray 1 to swing left and right relative to the fixed scraper ring 5. Each time the material 200 picks up the flux 100 in the groove of the tray 1, part of the flux 100 in the flux 100 in the groove is transferred to the material 200, which may cause the problem of insufficient flatness. After the groove of the tray 1 is scraped by the scraper ring 5, part of the flux 100 in the scraper ring 5 is transferred back to the groove and flattens the flux 100 in the groove, so that the flux 100 in the groove has a satisfactory flatness again, so that the next material 200 can pick up the flux 100.
[0041] Furthermore, if Figure 2As shown, the groove includes four reference points 111, which are respectively set at the four corners of the groove. Each reference point 111 is equidistant from the edge of the groove. When calibrating the flatness of the tray 1, the calibrator 4 sequentially measures the height of the soldering flux at the four reference points 111. In this embodiment, the groove of the tray 1 for holding the soldering flux 100 is configured as a regular rectangle, and the reference points 111 are set at the four corners of the rectangle. Therefore, after measuring the height at the four corners of the rectangle, the calibrator 4 can quickly and effectively determine whether the soldering flux 100 at these corners meets the flatness requirements, eliminating the need for additional positioning operations at intermediate positions. Furthermore, each height positioning of the calibrator 4 can maintain good consistency.
