[0002] Copper tube components are mainly used in refrigeration equipment such as air conditioners and refrigerators. Since the mainframe manufacturers have different designs for the mainframes, many copper tube components need to be customized. An air conditioner filter is a front-end device for the refrigerant of the air conditioner throttling device to pass through the capillary tube, ensuring the smooth flow of the refrigerant before entering the capillary tube. If there are impurities, they can be filtered in the filter and then flow to the capillary tube.

[0003] The copper tube filter joint is made of a copper tube section, as Figure 1 shown. The filter joint 100 includes a tubular body 101 and a reduced-diameter portion 102 at one end. A filter screen 103 is installed inside the filter joint 100. To prevent the filter screen 103 from falling off, a limiting groove 104 needs to be pressed on the filter joint 100 after the filter screen 103 is installed.

[0004] The above work is generally completed manually by workers, and its single processing mode has low efficiency and it is difficult to guarantee the quality. Content of the Utility Model

[0037] In order to enable those skilled in the art to better understand the technical solution of the present utility model, the present utility model will be further described in detail below in conjunction with the specific embodiments.

[0038] The Chinese patent application CN202111393504.0 in the prior art discloses a copper tube filter installation and dotting machine, including an installation base, on which a 4-station turntable is installed. A copper tube vibrating disk is installed on the left side of the installation base, a filter vibrating disk is installed on the front side, and a filter automatic pressing mechanism is installed on the right side; a copper tube automatic feeding mechanism is installed between the 4-station turntable and the copper tube vibrating disk in a cooperative manner, a filter automatic feeding mechanism is installed between the 4-station turntable and the filter vibrating disk in a cooperative manner, the copper tube automatic feeding mechanism cooperates with the automatic blanking mechanism, and the automatic blanking mechanism is connected to the automatic dotting mechanism.

[0039] The filter automatic feeding mechanism puts the filter into the copper tube by using the corresponding cylinder. The filter automatic pressing mechanism uses the cylinder for positioning and performs a pressing action to press the filter into the copper tube.

[0040] In the above prior art, first, it is impossible to ensure that the filter and the copper tube can be aligned. Once skewed, the filter will lie across the inside of the copper tube and become a waste product when pressed. Secondly, in order to ensure uniform force, the gap between the pressing mechanism and the filter is generally very small. After pressing the filter into the copper tube, the filter is easily taken out during the recovery process of the pressing mechanism, and even the filter connector can be taken out from the mounting seat, making the filter unable to be assembled in place. Finally, in the above prior art, it is impossible to determine whether a copper tube is missing a filter.

[0041] In order to solve the problems existing in the above prior art, such as Figure 2As shown in the figure, the utility model provides a copper tube filter screen assembly device, which includes a bottom plate 12 and a turntable 1 arranged on the bottom plate 12; a plurality of mounting seats 11 arranged along the circumference are provided on the turntable 1; it also includes a filter joint feeding mechanism 2 for feeding filter joints, a filter screen feeding mechanism 3 for feeding filter screens and placing the filter screens on the filter joints, a flattening mechanism 4 for pressing the filter screens flat on the filter joints, a stamping mechanism 5 for stamping the filter screens into the filter joints, and a detection mechanism 6 for detecting whether the filter screens are missing; a discharge hole is arranged on the bottom plate 11 behind the detection mechanism; the copper tube filter screen automatic installation machine also includes a limit groove pressing mechanism 8 for pressing limit grooves for the filter joints.

[0042] In the utility model, the filter screen is placed on the filter joint by the filter screen feeding mechanism 3, and then the filter screen and the filter joint are pressed flat by the flattening mechanism 4 so that the two are aligned, and then the stamping mechanism 5 is used for stamping to make the filter screen installed in place. Finally, it is detected by the detection mechanism 6 to avoid the situation of missing installation. In the utility model, the work of installing the filter screen is completed in three steps, thus ensuring the quality of filter screen installation and avoiding the situation in the prior art that the filter screen and the filter joint are not aligned and then stamped.

[0043] As Figure 3 shown, in this embodiment, the mounting seat 11 includes a mounting hole for accommodating the filter joint, and an annular sliding groove 13 corresponding to the circumferential position of the mounting hole is opened on the bottom plate 12; the discharge hole is opened on the annular sliding groove 13. When working, the filter joint is inserted into the mounting hole, and its reduced diameter part slides in the annular sliding groove 13 and can sequentially pass through the above-mentioned various processes under the drive of the turntable 1.

[0044] In this embodiment, the filter joint feeding mechanism 2 includes a hopper 21 connected to a vibrating feeding tray; the hopper 21 includes a conical section and a discharge pipe located below the conical section; the inner diameter of the discharge pipe is the same as the outer diameter of the filter joint body; the discharge pipe is located directly above the circumference where the mounting seat 11 is located, so that the filter joint can fall into the lower mounting seat 11 after sliding out of the discharge pipe.

[0045] The filter joints arranged in the vibrating feeding tray fall into the conical section with the reduced diameter end first. The conical section is similar to a funnel, ensuring that the filter joints will not flip in the conical section and also fall into the discharge pipe with the reduced diameter end first. Since the discharge pipe is directly above the circumference where the mounting seat 11 is located. When the mounting seat 11 moves to directly below the discharge pipe and pauses, the filter joint sliding out of the discharge pipe can just fall into the mounting seat 11.

[0046] As Figure 4As shown in the figure, in this embodiment, the filter feeding mechanism 3 includes a slideway 31; the feeding end of the slideway 31 is connected to a vibrating feeding tray, and the discharging end of the slideway 31 is connected to a clamping die; the clamping die includes two left and right modules 32, and grooves are respectively formed on the adjacent vertical surfaces of the two left and right modules 32, and the grooves on the two left and right modules can be combined into a sliding hole 33 for the filter to pass through; the sliding hole 33 is located directly above the circumference where the mounting seat 11 is located; the two left and right modules 32 are connected by an elastic connecting member such as a rubber band 35 and a pre-tightening force for driving the two modules 32 to approach each other is applied to the two left and right modules 32; a retractable punch I 34 is vertically arranged directly above the clamping die, and when the punch I 34 extends, the filter can be pushed from the sliding hole 33 into the filter connector in the lower mounting seat 11.

[0047] When the filter in the slideway 31 moves to the sliding hole 33, due to the pre-tightening force of the elastic connecting member, the two modules 32 are closely attached, making the sliding hole 33 smaller than the filter to ensure that the filter will not fall by itself. When the mounting seat 11 stops directly below the sliding hole 33, the punch I 34 extends to press down the filter. The two left and right modules 32 are separated under the action of the punch I 34, making the sliding hole 33 larger, so that the filter can fall onto the filter connector through the sliding hole 33 driven by the punch I 34. It should be noted that the punch I 34 will not directly press the filter into the filter connector, but only let the filter naturally fall onto the filter connector after passing through the sliding hole 33.

[0048] As Figure 5 shown in the figure, in this embodiment, the flattening mechanism 4 includes a pressing die 41 that can be driven by a cylinder 42 to move up and down, and the bottom surface of the pressing die 41 is a plane; the pressing die 41 is located directly above the circumference where the mounting seat 11 is located.

[0049] Since the filter naturally falls onto the filter connector at the filter feeding mechanism 3, it may not be completely aligned. Therefore, in the present invention, a flattening mechanism 4 is provided, and the filter is pressed into the filter connector by pressing down the pressing die 41. In this way, the opening of the filter connector is completely flush with the filter, preparing for the subsequent stamping.

[0050] As Figure 6 shown in the figure, in this embodiment, the stamping mechanism 5 includes a vertically arranged retractable punch II 51, and the punch II 51 is located directly above the circumference where the mounting seat 11 is located; an axial chute is formed on the punch II 51, and a stop rod 52 that penetrates the chute and can slide along the chute is further included; a return spring 53 is sleeved on the punch II 51, and the lower end of the return spring 43 is connected to the stop rod 52 to reset the stop rod 52; the length of the stop rod 52 is greater than the outer diameter of the filter connector.

[0051] The function of the stamping mechanism 5 is to stamp the filter screen in place. To avoid one-sidedness, the diameter of the punching rod II 51 is not much different from the inner diameter of the filter screen, so that the filter screen is evenly stressed and avoids skewing. However, it is found in the actual use process that due to the small gap between the two, the punching rod II 51 often brings out the filter screen when retracting from the filter adapter. To solve this problem, in this embodiment, a stop rod 52 that can slide axially along the punching rod II 51 is provided on the punching rod II 51. When stamping, the stop rod 52 can block at the opening of the filter adapter to prevent the punching rod II 51 from bringing out the filter screen when retracting, and at the same time prevent the entire filter adapter from being taken out of the mounting seat 11. In addition, the return spring 53 on the stop rod 52 can reset the stop rod 52 when the punching rod II 51 retracts, and at the same time can also apply a pre-tightening force to the stop rod 52 to press it against the opening of the filter adapter.

[0052] As Figure 7 shown, in this embodiment, the detection mechanism 6 includes a vertically arranged and telescopic probe 61, and the probe 61 is located directly above the circumference where the mounting seat 11 is located; the probe 61 is connected to an alarm, and a lower limit position is set in the stroke of the probe 61, so that when the probe 61 descends beyond the lower limit position and still does not encounter resistance, the alarm sounds.

[0053] After the probe 61 descends a distance exceeding the lower limit position, it indicates that there is no filter screen installed in the filter adapter. In the case of installing a filter screen, the probe will encounter the resistance of the filter screen before descending to the lower limit position. In addition, the probe 61 can also reposition the filter screen lifted by the punching rod II 51, playing a role in ensuring that the filter screen is installed in place.

[0054] As Figure 8 shown, a discharge pipe 7 is connected to the discharge hole, and the discharge pipe 7 uses compressed air to drive the filter adapter to move towards the limit groove pressing mechanism 8. After the filter screen is installed, the filter adapter passes through the discharge hole, slides into the discharge pipe 7 from the discharge hole, and then is pushed to the next process, that is, the limit groove pressing mechanism 8, under the action of compressed air.

[0055] As Figure 9 shown, in this embodiment, the limit groove pressing mechanism 8 includes two left and right rollers 81 arranged side by side, and the two left and right rollers 81 rotate in the same direction; it also includes a pressure roller 82 arranged directly above the two left and right rollers 81; the pressure roller 82 can be lifted and lowered, and an annular boss 83 is arranged on the outer ring surface of the pressure roller 82.

[0056] The filter joint sliding out from the discharge pipe 7 is pushed between the two rollers 81 and starts to rotate driven by the two rollers 81. At this time, the pressing roller 82 presses downwards, so that the annular boss 83 on the rotating pressing roller 82 acts on the side wall of the filter joint, thereby pressing an annular limiting groove on the side wall of the filter joint, so that the filter screen cannot fall off from the filter joint.

[0057] In order to realize automatic blanking in this embodiment, the limiting groove pressing mechanism 8 further includes a blanking shovel 84; the blanking shovel 84 is sheet-shaped and is arranged along a direction tangent to one of the rollers 81 and the filter joint to be processed; the blanking shovel 84 is telescopic. When the blanking shovel 84 extends, it can extend between the roller 81 and the filter joint. After the high-speed rotating filter joint touches the blanking shovel 84, it will be automatically bounced off to realize automatic blanking.

[0058] The above is only the preferred embodiment of the present invention. It should be noted that the above preferred embodiment should not be regarded as a limitation of the present invention. The protection scope of the present invention should be subject to the scope defined by the claims. For those of ordinary skill in the art, without departing from the spirit and scope of the present invention, several improvements and retouches can be made, and these improvements and retouches should also be regarded as the protection scope of the present invention.
