DETAILED DESCRIPTION

[0025] It should be noted that the embodiments in the application and the features in the embodiments can be combined with each other without conflict. The application will be described in detail below with reference to the drawings and in combination with the embodiments.

[0026] ​​​​In order to enable personnel in the technical field to better understand the scheme of the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below in combination with the drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative labor should fall within the scope of protection of the present application.

[0027] As shown in Figures 1-5 The present application provides a soldering robot smoke suction device, which comprises a placing assembly 1, the placing assembly 1 comprises a base 11, two groups of guide rails 13 are fixedly installed on the base 11, and a workpiece plate 14 for soldering workpieces is slidably installed on the two groups of guide rails 13, the workpiece plate 14 is used for soldering workpieces, and a cylinder 12 is fixedly installed on the base 11, the output end of the cylinder 12 is connected with the workpiece plate 14, and the workpiece plate 14 is adapted to move linearly with the output end of the cylinder 12 to move to a designated soldering position;

[0028] A soldering assembly 2 is installed on the base 11, the soldering assembly 2 comprises two groups of support rods 21 fixedly installed on the base 11, a first moving unit is connected between the two groups of support rods 21, the first moving unit comprises a bottom plate 22 fixedly connected between the two groups of support rods 21, protruding plates (not marked in the figure) are arranged on the bottom plate 22 near both ends, a lead screw 23 is bearing-connected between the two protruding plates, a first sliding block 25 is threadedly connected on the lead screw 23, and a motor 24 is fixedly installed on one side of one of the protruding plates, the output end of the motor 24 is connected with the lead screw 23;

[0029] When the motor 24 is started, the output end of the motor 24 drives the lead screw 23 to rotate, and since the first sliding block 25 is threadedly connected with the lead screw 23, the rotary motion of the lead screw 23 is converted into the linear motion of the first sliding block 25 in the axial direction of the lead screw 23, and two groups of sliding rails (not shown in the figure) are fixedly installed on the bottom plate 22 and located on both sides of the lead screw 23, so that the first sliding block 25 can slide on the two groups of sliding rails, thereby further linearly limiting the moving direction of the first sliding block 25;

[0030] A second moving unit 26 is installed on the first sliding block 25, the second moving unit 26 and the first moving unit are similar structures, and the second moving unit 26 is perpendicular to the first moving unit, and the first sliding block 25 of the second moving unit 26 is defined as a second sliding block, and a soldering robot arm 27 having a soldering gun is fixedly installed on the second sliding block;

[0031] When the X-axis adjustment of the soldering position is needed, the motor 24 is started to drive the screw rod 23 connected thereto to rotate, and the rotary motion of the screw rod 23 is converted into the linear motion of the first sliding block 25 along the screw rod 23 in the axial direction;

[0032] When the Y-axis adjustment of the soldering position is needed, the motor 24 in the second moving unit 26 is started to drive the second sliding block (i.e. the first sliding block 25 in the second moving unit 26) to move linearly in the vertical direction, so that the soldering gun starts to work when the soldering machine arm 27 moves to the target position, and the soldering operation is carried out at the corresponding position, so that flexible and accurate soldering operation is achieved.

[0033] In some practical applications, in order to collect the smoke generated during soldering, referring to Figures 2 to 4 , a side plate 28 is fixedly installed on the second sliding block, and a smoke suction assembly 3 is installed on the side plate 28. The smoke suction assembly 3 includes a third moving unit 31 installed on the side plate 28. The third moving unit 31 and the first moving unit are similar structures, and the third moving unit 31 is vertically arranged. Here, the first sliding block 25 of the third moving unit 31 is defined as a third sliding block (see Figure 3 );

[0034] Two connecting rods 32 are fixedly installed on both sides of the third sliding block, and an arc-shaped air suction box 33 is connected to one end of the two groups of connecting rods 32. A slot 34 is formed in the arc-shaped air suction box 33, and an arc-shaped mesh plate 36 is movably inserted into the slot 34. Meanwhile, an open slot 35 is formed on one side of the arc-shaped air suction box 33 close to the soldering gun, so that the arc-shaped mesh plate 36 can face the soldering gun.

[0035] Furthermore, the arc-shaped mesh plate 36 has two groups of lapping plates 37, which are arranged in an arc shape. It should be noted that the diameter of the lapping plate 37 at the upper end is greater than that of the lapping plate 37 at the lower end, so that when the arc-shaped mesh plate 36 is inserted into the slot 34, a smoke suction space can be built between the arc-shaped mesh plate 36 and the open slot 35. Meanwhile, the lapping plate 37 at the upper end is lapped on the arc-shaped air suction box 33. Meanwhile, a first hose 310 is communicated and installed on the arc-shaped air suction box 33, and the first hose 310 is connected to the smoke suction space.

[0036] In this application, a sealing gasket is arranged at the contact area between the arc-shaped mesh plate 36 and the arc-shaped air suction box 33 to increase the sealing performance when the arc-shaped mesh plate 36 is installed in the slot 34.

[0037] When the height position of the arc-shaped suction box 33 needs to be adjusted, the motor 24 in the third moving unit 31 is started (similar in structure to the first moving unit). Then the third sliding block is driven to move, and when the third sliding block moves up and down, the connecting rod 32 fixedly connected thereto will move accordingly, thereby driving the arc-shaped suction box 33 connected to one end of the connecting rod 32 to move up and down, so as to adjust the height position of the arc-shaped suction box 33 to adapt to different soldering operation scenes;

[0038] And two groups of screw rods 38 are fixedly installed on the arc-shaped suction box 33, and a positioning hole (refer to Figure 4 ) with a diameter matched with the screw rod 38 is formed on the upper end of the clamping plate 37. When the arc-shaped mesh plate 36 slides into the slot 34, the positioning hole is synchronously sleeved on the screw rod 38, and the butterfly nut 39 is threadedly connected to the screw rod 38. The butterfly nut 39 can be screwed tightly to tightly fix the arc-shaped mesh plate 36 and the arc-shaped suction box 33, so as to ensure the size stability of the smoke suction space built between the open slot 35 and the clamping plate 37. The stable smoke suction space is beneficial to maintaining constant airflow, improving the collection efficiency of soldering smoke, and ensuring the working performance of the smoke suction assembly 3;

[0039] Meanwhile, an air purification box 311 is installed on the side of one group of supporting rods 21, and an air filter plate 314 is slidably inserted into the side of the air purification box 311. The air filter plate 314 can be made of glass fiber filter paper or activated carbon fiber filter core. Meanwhile, a side slot 313 with a width matched with the air filter plate 314 is formed on the side of the air purification box 311, and a frame 315 is fixedly installed in the inside of the air purification box 311. The frame 315 is used to support and place the air filter plate 314 in the inside of the air purification box 311. The other end of the first hose 310 has a sleeving part (not marked in the figure), which is fixedly connected to the bottom of the air purification box 311. A gas pump 312 is fixedly installed on the air purification box 311. The gas pump 312 has a suction port, which is in communication with the air purification box 311;

[0040] During soldering operation, the third moving unit 31 drives the arc-shaped suction box to move to a suitable position to collect the smoke generated by the soldering gun. The smoke enters the smoke suction space through the arc-shaped mesh plate 36, and under the action of the gas pump 312, the smoke is sucked into the air purification box 311 through the first hose 310. Since one end of the first hose 310 is in communication with the smoke suction space, and the other end is fixedly connected to the bottom of the air purification box 311 through the sleeving part, a smoke transmission channel is built;

[0041] When the air pump 312 is turned on, the suction port draws air in the air purification box 311, forming a negative pressure in the box, and the smoke quickly flows in. When the smoke passes through the air filter plate 314, the harmful substances and particles in the smoke are intercepted and filtered by the filter, achieving purification. The air pump 312 continues to work, discharging the purified air out of the air purification box 311, while maintaining the negative pressure in the box, so that the arc-shaped air suction box 33 continuously collects smoke, and the first hose 310 stably transmits the smoke.

[0042] In some practical applications, in order to evenly distribute the smoke entering the air purification box 311, and to avoid over-utilization of some local positions of the air filter plate 314, causing poor filtering effect in some positions, as shown in Figure 5 A fourth moving assembly 4 is installed in the air purification box 311. The fourth moving assembly 4 and the first moving unit have similar structures. Here, the first slider 25 of the fourth moving assembly 4 is defined as a fourth slider (see Figure 3 ), and a fixed ring 41 is fixedly installed on the fourth slider. An air inlet cover 42 is fixedly installed in the fixed ring 41, and a second hose 43 is connected between the air inlet cover 42 and the sleeve joint portion.

[0043] Since the fourth moving assembly 4 and the first moving unit have similar structures, when it is necessary to adjust the position of the air inlet cover 42, the motor 24 in the starting assembly (similar to the first moving unit) is started, thereby driving the fourth slider to move linearly.

[0044] The fourth slider drives the fixed ring 41 to move, and the air inlet cover 42 in the fixed ring 41 moves accordingly, achieving position adjustment of the air inlet cover 42 in the air purification box 311. The smoke generated during the soldering process is transmitted through the arc-shaped air suction box 33 and the first hose 310. The second hose 43 connects the air inlet cover 42 and the sleeve joint portion of the first hose 310, and the smoke enters the air inlet cover 42 through the second hose 43.

[0045] Under the action of the air pump 312, a negative pressure is formed in the air purification box 311, and the smoke is sucked into the purification box from the air inlet cover 42. By controlling the fourth moving assembly 4, the air inlet cover 42 moves at different positions in the purification box, changing the position and direction of the smoke entering the purification box, avoiding concentrated impact of the smoke on a certain local position of the air filter plate 314, and allowing the smoke to be evenly distributed in the air purification box 311, so that each part of the air filter plate 314 can fully play a filtering role.

[0046] The above description is only a preferred embodiment of the present application and is not intended to limit the present application. Those skilled in the art can make various modifications and changes to the present application. Any modification, equivalent replacement, improvement, etc. made within the spirit and principles of the present application shall be included in the protection scope of the present application.
