Description

Technical Field

[0002] Flux can be classified into solid, liquid and paste according to its form. Paste flux, also known as solder paste flux, is a commonly used welding auxiliary material in electronic assembly, especially in surface mount technology (SMT) and through-hole technology (THT). It is usually in the form of a paste with a certain viscosity.

[0003] In the related technology, rolling the paste flux is an important step to ensure its performance optimization, improve the welding pretreatment effect and the final welding quality. When rolling the paste flux, it is mostly done by rolling a pair of rollers to improve the uniformity and fluidity of the paste flux.

[0004] However, when rolling the paste flux, relevant staff are required to pour the paste back and forth on the surface of the rolling roller along the length direction to improve the uniform rolling of the paste by the rolling roller. This method has poor continuity and efficiency. After the rolling rollers finish rolling the paste flux, an inclined discharge plate is usually set to allow the paste to slide naturally. However, since the paste has a certain viscosity, the efficiency of natural sliding is low. When collecting the paste, relevant staff still use a scraper to manually scrape the paste on the discharge plate. Summary of the invention

DETAILED DESCRIPTION

[0025] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, and should not be construed as limiting the present invention.

[0026] The paste soldering flux rolling feeding device according to the embodiment of the utility model is described below with reference to the accompanying drawings.

[0027] like Figure 1 and Figure 2As shown, the paste flux rolling and feeding device of the embodiment of the utility model may include a mounting frame 100 , a rolling device 200 , a reciprocating device 300 , a feeding hopper 400 and a scraping device 500 .

[0028] The bottom of the mounting frame 100 is provided with an inclined blanking plate 101 , and the bottom of the blanking plate 101 is provided with supporting legs for supporting the entire device.

[0029] The rolling device 200 is disposed in the mounting frame 100 , the reciprocating device 300 is disposed above the rolling device 200 , and the feed hopper 400 is disposed on the moving end of the reciprocating device 300 .

[0030] It should be noted that the bottom discharge end of the feed hopper 400 faces the rolling end of the rolling device 200 , so as to facilitate pouring the paste flux in the feed hopper 400 onto the rolling device 200 .

[0031] like Figure 4 As shown, the scraping device 500 includes a chain structure 510 , a scraper 520 and a first driving motor 530 .

[0032] Among them, the chain structure 510 is arranged between the rolling device 200 and the blanking plate 101, the scraper 520 is arranged on the moving end of the chain structure 510, and the first driving motor 530 is connected to the chain structure 510. Among them, when the scraper 520 rotates to the blanking plate 101, the bottom of the scraper 520 is in contact with the blanking plate 101.

[0033] It should be noted that the chain structure 510 is arranged parallel to the inclined blanking plate 101 to ensure that when the connection structure drives the scraper 520, the scraper 520 can push the blanking plate 101 in parallel, thereby achieving a better scraping effect.

[0034] Specifically, when the relevant staff members are rolling the paste flux, first, the relevant staff members pour the paste flux into the feed hopper 400, and turn on the rolling device 200 and the reciprocating device 300, then the reciprocating device 300 drives the feed hopper 400 to reciprocate above the rolling device 200, and during the reciprocating movement, the feed hopper 400 evenly pours the paste flux onto the rolling device 200.

[0035] As the rolling device 200 rolls, the paste flux drips from the rolling device 200 onto the blanking plate 101, and slowly flows from the inclined blanking plate 101 to the bottom. Relevant staff can place a containing box at the bottom of the blanking plate 101 to receive the rolled paste flux.

[0036] After the rolling is completed, the relevant staff can start the scraping device 500, that is, by starting the first drive motor 530, the chain structure 510 rotates, thereby driving the movement of the scraper 520, so that the scraper 520 can push the paste flux from the high end of the unloading plate 101 to the bottom end, and flow into the containing box to accelerate the unloading.

[0037] In one embodiment of the present invention, Figure 4 As shown, the chain structure 510 includes a sprocket 511 and a conveyor chain 512 .

[0038] The conveying chain 512 is sleeved on the two sprocket wheels 511 to connect the two sprocket wheels 511 , and the scraper 520 is fixedly arranged on the conveying chain 512 .

[0039] It should be noted that the output end of the first drive motor 530 is connected to one of the sprockets, and the first drive motor 530 drives the sprocket connected thereto to rotate, so that the conveyor chain rotates on the sprocket, thereby realizing the movement of the scraper 520.

[0040] As a possible situation, there are two chain structures 510, and the two chain structures 510 are arranged opposite to each other. The sprockets 511 in the two chain structures 510 correspond to each other one by one and are respectively connected by connecting shafts 501. The two ends of the scraper 520 are respectively fixed on the conveying chains 512 of the two chain structures 510.

[0041] It should be noted that by providing two opposite chain structures 510 , the scraper 520 can be made more stable during movement.

[0042] In one embodiment of the present invention, Figure 3 As shown, the reciprocating device 300 includes a second driving motor 310 , a bidirectional lead screw 320 , a lead screw slider 330 , a stabilizing rod 340 and a sliding sleeve 350 .

[0043] Among them, the second drive motor 310 is arranged on the mounting frame 100, the bidirectional screw 320 is rotatably arranged in the mounting frame 100, the stabilizing rod 340 is fixedly arranged in the mounting frame 100, the screw slider 330 and the sliding sleeve 350 are respectively arranged on both sides of the feed hopper 400, and the screw slider 330 is arranged on the bidirectional screw 320, and the sliding sleeve 350 is slidably arranged on the stabilizing rod 340.

[0044] It should be noted that when the reciprocating device 300 is started, the second drive motor 310 drives the bidirectional screw 320 to rotate, and the screw slider 330 moves on the bidirectional screw 320 to drive the movement of the feed hopper 400. At the same time, the sliding sleeve 350 slides on the stabilizing rod 340. Through the setting of the sliding sleeve 350 and the stabilizing rod 340, the feed hopper 400 can be made more stable when moving.

[0045] In one embodiment of the utility model, a discharge port is opened at the bottom of the feed hopper 400, and a switch valve is provided in the discharge port. Relevant staff can adjust the discharge amount of the paste flux by controlling the opening of the switch valve, thereby achieving more accurate discharge of the paste flux.

[0046] In one embodiment of the present invention, the rolling device 200 includes a third driving motor 210 , a rolling roller 220 and a gear 230 .

[0047] Among them, the third driving motor 210 is arranged on the mounting frame 100, the two rolling rollers 220 are arranged opposite to each other and can be rotatably arranged in the mounting frame 100, the two gears 230 are coaxially arranged with the two rolling rollers 220, and the two gears 230 are meshed and connected, wherein the output end of the third driving motor 210 is connected to one of the rolling rollers 220.

[0048] It should be noted that when the laminating device 200 is started, the third driving motor 210 drives the laminating roller 220 connected thereto to rotate, and the other laminating roller 220 reverses due to the meshing action of the two gears 230, thereby realizing the two laminating rollers 220 rotating in opposite directions to achieve the extrusion of the paste flux.

[0049] As a possible scenario, Figure 5 As shown, baffles 201 are provided on both sides of the laminating roller 220 , and the baffles 201 are fixed in the mounting frame 100 through support rods 202 , and the bottom sides of the baffles 201 are respectively in contact with the two laminating rollers 220 .

[0050] It should be noted that the relevant staff adjusts the moving path of the reciprocating device 300 so that the moving path of the moving end of the reciprocating device 300 is between the two baffles 201, so as to limit the rolling range of the rolling roller 220, thereby preventing subsequent paste flux from falling onto the chain structure 510.

[0051] In one embodiment of the utility model, a controller is provided on the mounting frame 100, and the rolling device 200, the reciprocating device 300 and the scraping device 500 are respectively connected to the controller. Relevant staff can control the rolling device 200, the reciprocating device 300 and the scraping device 500 respectively through the controller to improve the degree of automation.

[0052] In summary, according to the paste flux rolling and unloading device of the embodiment of the utility model, by setting the feed hopper 400 on the moving end of the reciprocating device 300, the feed hopper 400 can move with the reciprocating device 300 and pour the paste flux on the rolling device 200, which has better continuity and effect, and a scraping device 500 is provided on the unloading plate 101, which can automatically scrape out the paste flux on the unloading plate 101, reducing manual operation and improving efficiency.
