Description

Technical Field

[0001] This utility model relates to the technical field of radiator production equipment, specifically a radiator tube feeding device. Background Technology

[0002] Radiators are commonly used in automotive cooling systems. Radiators are typically square-shaped and consist of several parts, including a water chamber (inlet / outlet chamber), a radiator core (composed of alternating heat dissipation strips and heat pipes), a main board, and side panels. During assembly, the radiator core needs to be arranged first, which involves arranging the heat dissipation strips and heat pipes alternately.

[0003] The current method of feeding, sorting, and conveying heat pipes during radiator assembly typically relies on manual labor or semi-automated equipment, which has the following technical drawbacks:

[0004] (1) Manual material loading is inefficient and has poor precision. Manual placement of heat sinks is prone to misalignment, which affects the quality of subsequent assembly. In addition, the labor intensity is high and the production efficiency is limited by the worker's operating speed.

[0005] (2) Existing automated equipment lacks stability. For example, if a robotic arm is used to grip the heat sink, direct clamping can easily deform the heat sink and cause scratches on the surface of the pipe. In addition, belt conveyors have no correction function and simply transport the heat sink, which can easily cause the heat sink to stack or shift, requiring additional manual intervention. Utility Model Content

[0006] The purpose of this invention is to overcome the shortcomings of the prior art and provide a heat sink feeding device that is highly accurate and self-correcting.

[0007] To achieve the above objectives, the following technical solution is adopted:

[0015] Furthermore, the connecting plate is also provided with sensors for detecting the movement of the stepped shaft, and the number and position of the sensors correspond to the stepped shaft.

[0020] Furthermore, the pulleys of the conveyor belt are driven by a servo motor.

[0021] The beneficial effects of this utility model are:

Detailed Implementation

[0032] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0033] Example 1

[0034] refer to Figure 1-5The heat sink feeding device includes a frame 1 and a suction cup picking assembly, a vertical drive assembly, a horizontal drive assembly and a feeding assembly mounted on the frame 1.

[0035] The suction cup material handling assembly includes a support frame 21, a suction cup frame 22, and multiple suction cups 27. The lower end of the suction cup frame 22 has two spaced-apart suction cup receiving plates 23, and the multiple suction cups 27 are spaced-apart on the suction cup receiving plates 23. The suction cup frame 22 is connected to the frame 1 via the support frame 21; the suction cups 27 are connected to an external vacuum device.

[0036] The lateral drive assembly is used to drive the suction cup holder 22 to move laterally. Specifically, the lateral drive assembly includes a second motor 41, a second gear 42, a second rack 43, and a second linear guide rail 44. The second motor 41 is mounted on the support frame 21, the second gear 42 is driven by the second motor 41, the second rack 43 is mounted on the frame 1 and meshes with the second gear 42, and the second linear guide rail 44 is laterally positioned between the frame 1 and the support frame 21. In use, the second motor 41 drives the second gear 42 to rotate via a transmission wheel and a transmission belt. Since the second rack 43 is fixed on the frame 1, the rotation of the second gear 42 will drive the entire suction cup picking assembly to move laterally along the second linear guide rail 44, allowing it to move above the heat dissipation pipe material storage.

[0037] The vertical drive assembly is used to drive the suction cup holder 22 to move up and down. Specifically, the vertical drive assembly includes a first motor 31, a first gear 32, a first rack 33, and a first linear guide rail 34. The first motor 31 is mounted on the support frame 21, the first gear 32 is connected to the output shaft of the first motor 31, the first rack 33 is vertically mounted on the suction cup holder 22 and meshes with the first gear 32, and the first linear guide rail 34 is vertically positioned between the suction cup holder 22 and the support frame 21. In use, the first motor 31 drives the first gear 32 to rotate, and the rotation of the first gear 32 causes the suction cup holder 22 to descend along the first linear guide rail 34, causing the suction cup 27 to contact the heat sink. After the suction cup 27 (vacuum adsorption) picks up the heat sink, the first motor 31 reverses direction, and the suction cup holder 22 rises, completing the material retrieval.

[0038] More preferably, the suction cup holder 22 is provided with a connecting plate 24, and the connecting plate 24 is provided with stepped shafts 25 for detecting the height position of the heat sink. The connecting plate 24 is provided with a through hole, the small diameter section of the stepped shaft 25 passes through the through hole, the large diameter section of the stepped shaft 25 is located above the through hole, and the lower end of the stepped shaft 25 is lower than the lower end of the suction cup 27. The number of stepped shafts 25 is equal to the number of suction cups 27 in one suction cup receiving plate 23, and their positions correspond. The connecting plate 24 is also provided with sensors 26 for detecting the movement of the stepped shafts 25, and the number and position of the sensors 26 correspond to the stepped shafts 25.

[0039] When the suction cup holder 22 moves downwards to pick up the heat sink, the stepped shaft 25 first touches the heat sink and then extends upwards. When each stepped shaft 25 extends upwards, it indicates that the position and quantity of the heat sink in the heat sink material library are normal. At this time, after the sensor 26, which is used to detect the movement of the stepped shaft 25, senses it, the suction cup 27 picks up the heat sink.

[0040] Then, the suction cup assembly moves laterally, transporting the heat sink pipe directly above the feeding assembly.

[0041] The feeding assembly is located below the suction cup picking assembly. The feeding assembly includes a feeding correction assembly and a conveyor belt 54. The conveyor belt 54 is located below the feeding correction assembly and has protrusions 541 for separating the heat dissipation pipes. The pulleys of the conveyor belt 54 are driven by a servo motor.

[0042] The feeding correction assembly includes a feeding guide 51 and a retractable baffle 52. The feeding guide 51 has spacer ribs 511, the spacing width of which corresponds to the spacing width of the protrusions 541. The retractable baffle 52 can be used to prevent the heat dissipation pipes on the feeding guide 51 from falling downwards. Specifically, the feeding guide 51 is provided with a horizontal through groove. The retractable baffle 52 includes a baffle 52 and a cylinder 53. The baffle 52 is connected to the cylinder 53 and passes through the through groove. The baffle 52 is provided with spaced-apart teeth 521, which are staggered with the spacer ribs 511.

[0043] A presence detection sensor (not shown in the figure) is provided on the frame 1 below the conveyor belt 54 to sense whether the heat sink is in place.

[0044] Initially, baffle 52 (driven by cylinder 53) extends to block the heat dissipation pipe and prevent it from falling directly. When the detection sensor detects that the heat dissipation pipe is above baffle 52, the position of conveyor belt 54 is adjusted by servo motor so that the position of the rib 541 on the conveyor belt 54 corresponds to the position of the rib of the feed guide 51, ensuring consistent spacing. At this point, the correction is complete, cylinder 53 retracts baffle 52, and the heat dissipation pipe falls onto conveyor belt 54 under gravity.

[0045] The above are merely preferred embodiments of this utility model, but the scope of protection of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the scope of protection of this utility model. Therefore, the scope of protection of this utility model should be determined by the scope of the claims.
