[0002] In the automotive manufacturing industry, the performance of heat sinks plays a crucial role in the vehicle's heat dissipation effect. To improve heat dissipation efficiency, heat sinks typically undergo electroplating to enhance their surface properties and corrosion resistance. After electroplating, the mounting brackets and the heat sinks installed within them need to be weighed to determine whether the electroplating solution has entered the brackets. In traditional heat sink mounting bracket processing, the gripping and weighing of the brackets mainly rely on manual operation. This method is not only inefficient but also susceptible to human factors, leading to inaccurate weighing results. Utility Model Content

[0020] Preferred embodiments of the present invention will now be described with reference to the accompanying drawings. Those skilled in the art should understand that these embodiments are merely illustrative of the technical principles of the present invention and are not intended to limit the scope of protection of the present invention.

These are used merely for ease of description and do not indicate or imply that the device or element must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.
[0022] Furthermore, it should be noted that, in the description of this utility model, unless otherwise explicitly specified and limited, the terms "set," "connected," and "linked" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.
[0023] like Figures 1 to 5 As shown, the automotive radiator hanger 1 of this utility model includes a weighing station equipped with a weighing platform 2 for weighing and testing the hanger 1 with radiator fins; a robotic arm 3 equipped with a gripping unit for gripping the hanger 1 that has passed the weighing on the weighing platform 2; the gripping unit includes at least a base frame 41 and a first clamping plate 42 and a second clamping plate 43 configured on the base frame 41 that can move in opposite directions or in opposite directions, and a drive structure for driving the first clamping plate 42 and the second clamping plate 43 to move synchronously.
[0024] See Figure 5 The mounting bracket 1 includes a carrier section and a pressing section. The carrier section has a space for placing the heat sink. The pressing section presses and fixes the heat sink onto the carrier section with multiple bolts, so that only one surface of the heat sink is electroplated during the electroplating process.
[0025] See Figures 1 to 4The drive end of the robotic arm 3 is equipped with a gripping unit. The gripping unit includes at least a base frame 41 and at least one set of first clamping plates 42 and second clamping plates 43 arranged on the base frame 41 that can move in opposite directions or in opposite directions, as well as a drive structure for controlling the first clamping plates 42 and second clamping plates 43 to move synchronously. The robotic arm 3 moves to the weighing station by driving the gripping unit, and uses the gripping unit to grip and transport the hanger 1 that has been weighed and detected on the weighing platform 2, so as to facilitate the subsequent weighing and detection of the hanger 1 loaded with heat sinks. In this way, the manual handling cost can be reduced and the handling efficiency of the hanger 1 can be improved.
[0026] After the heat sink inside the hanger 1 is electroplated, the hanger 1 and the heat sink need to be weighed to confirm whether the electroplating solution has entered the hanger 1. Specifically, the hanger 1 and the electroplated car heat sink inside the hanger 1 are transported to the weighing platform 2 at the weighing station. After the weighing platform 2 weighs and tests the hanger 1, the hanger 1 that meets the weight standard is picked up and unloaded by the robotic arm 3 using the gripping unit. That is, the robotic arm 3 controls the first clamping plate 42 and the second clamping plate 43 to be located on both sides of the hanger 1, and then uses the drive structure to control the first clamping plate 42 and the second clamping plate 43 to move towards each other to clamp the hanger 1. Under the transfer and gripping functions of the robotic arm 3, the hanger 1 is removed from the weighing platform 2 and placed in the next station. It has the characteristics of simple structure and convenient operation. Moreover, the method of gripping the hanger 1 by the robotic arm 3 and the gripping unit can reduce labor costs and improve the weighing and handling efficiency of the hanger 1, which is practical.
[0027] In one or more embodiments, the drive structure includes at least a first rack 51 mounted on the inner side of the first clamping plate 42, a second rack 52 mounted on the inner side of the second clamping plate 43, and a gear 53 rotatably mounted on the base frame 41. The first rack 51, the second rack 52 and the gear 53 are meshed together. The drive structure also includes a drive device configured on the base frame 41. The drive device is used to drive the gear 53 to rotate. The drive device may be a servo motor or a rotary cylinder.
[0028] See Figure 3 , Figure 4 The first rack 51 installed on the inner side of the first clamping plate 42 and the second rack 52 installed on the inner side of the second clamping plate 43 are parallel to each other. The first rack 51 and the second rack 52 are meshed with the gear 53, and the driving device is used to drive the gear 53 to rotate. Specifically, when clamping the hanger 1, the robot arm 3 is first controlled to place the first clamping plate 42 and the second clamping plate 43 on both sides of the hanger 1. Then, the driving device is used to control the gear 53 to rotate, so that the first rack 51 and the second rack 52 drive the first clamping plate 42 and the second clamping plate 43 to move towards each other, thereby clamping the hanger 1. Then, the robot arm 3 is used to move the hanger 1. It has the characteristics of simple structure and convenient operation, and is practical.
[0029] In one or more embodiments, pads 6 are disposed on the inner sides of the first clamping plate 42 and the second clamping plate 43.
[0030] See Figure 3 , Figure 4 The pad 6 is made of rubber. At least two sets of pads 6 are provided on the inner side of the first clamping plate 42 and the second clamping plate 43 to ensure the stability of the first clamping plate 42 and the second clamping plate 43 in clamping the hanger 1.
[0031] In one or more embodiments, a light rod 7 is disposed on the first clamping plate 42, and the light rod 7 passes through the second clamping plate 43. See also Figure 3 , Figure 4 The guide rod 7 is used to restrict the position of the first clamping plate 42 and the second clamping plate 43, so that the first clamping plate 42 and the second clamping plate 43 can only move towards each other or away from each other. At the same time, by restricting the first clamping plate 42 and the second clamping plate 43 by the guide rod 7, the stability of the movement of the first clamping plate 42 and the second clamping plate 43 can be ensured, and the stability of the clamping of the hanger 1 can be ensured.
[0032] In one or more embodiments, the robotic arm 3 is driven by a linear module 8 configured on the side of the weighing station.
[0033] See Figure 1 The linear module 8 is a mature technology. The linear module 8 is used to drive the robot 3 to perform linear motion, thereby realizing the adjustment of the position of the robot 3, increasing the handling and conveying range of the robot 3 for the hanger 1, and improving the applicability of this application.
[0034] In one or more embodiments, a limiting structure is provided on the inner side of the first clamping plate 42 and / or the second clamping plate 43 to limit the distance between the first clamping plate 42 and the second clamping plate 43. The limiting structure includes at least a driving cylinder 91 disposed on the inner side of the first clamping plate 42 and / or the second clamping plate 43 and a limiting member 92 driven by the driving cylinder 91.
[0035] See Figure 3 , Figure 4The limiting structure includes a drive cylinder 91 and a limiting member 92 disposed on the extended shaft end of the drive cylinder 91. The limiting member 92 can be a metal rod. There can be two sets of drive cylinders 91, which are respectively disposed on the opposing surfaces of the first clamping plate 42 and the second clamping plate 43. Specifically, the extension length of the limiting member 92 is controlled by the drive cylinder 91, thereby limiting the minimum distance between the first clamping plate 42 and the second clamping plate 43, controlling the position of the first clamping plate 42 and the second clamping plate 43, and avoiding the problem of deformation of the first clamping plate 42, the second clamping plate 43, or the hanging device 1 due to excessive clamping of the first clamping plate 42 and the second clamping plate 43. It should be noted that the drive cylinder 91 is located in the upper position relative to the first clamping plate 42 and the second clamping plate 43. This arrangement can avoid the problem of interference between the drive cylinder 91 and the hanging device 1 when the first clamping plate 42 and the second clamping plate 43 clamp the hanging device 1.
[0036] In one or more embodiments, the weighing station has a base on which a box 11 with a top opening is disposed, and the weighing platform 2 is disposed inside the box 11; the weighing station is also provided with a vision camera 12 to detect the position of the hanger 1 on the weighing platform 2; and the weighing station is provided with a waste rack 13 on the side of the weighing platform 2.
[0037] See Figure 1 , Figure 5 The weighing platform 2 is configured inside the box 11 with an opening at the top. The box 11 can collect the electroplating liquid dripping from the hanger 1, reducing pollution. The vision camera 12 installed at the weighing station is used to detect the position of the hanger 1 on the weighing platform 2, further ensuring the accuracy of the weighing platform 2 in detecting the weight of the hanger 1. The waste rack 13 is used to store hangers 1 that do not meet the weighing standards, making it convenient for workers to unload the materials.
