Description

Technical Field

[0001] This utility model relates to the field of clamping structures for loading and unloading machines for radiator testing, and more particularly to a clamping structure for loading and unloading machines for radiator testing. Background Technology

[0002] In the manufacturing process of heat sinks, heat sink inspection is a crucial step in ensuring product quality. With the continuous expansion of heat sink applications, their models and specifications are becoming increasingly diverse, such as laptop cooling modules, automotive radiators, and industrial heat sinks. Different models of heat sinks vary significantly in size, material, and structure, which places higher demands on the clamping structure of the loading and unloading machines used for heat sink inspection.

[0003] For different types of heat sinks, such as thin and light laptop heat sinks and heavy-duty car radiators, traditional clamping structures cannot meet the clamping requirements simultaneously. For thin and light heat sinks, traditional rigid clamping methods can easily lead to workpiece deformation or surface damage; while for heavy-duty heat sinks, vacuum adsorption alone cannot provide sufficient clamping force, posing a risk of workpiece slippage.

[0004] Existing radiator inspection clamping structures are mostly designed for single-model radiators, resulting in poor compatibility. When different models of radiators need to be inspected, the entire set of clamps often needs to be replaced, which not only takes a long time (usually 15-30 minutes) to change models, increasing production downtime, but also raising tooling costs. Therefore, a new radiator inspection clamping structure is proposed to solve the above problems. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a clamping structure for a radiator inspection loading and unloading machine, which aims to improve the problems of "poor compatibility of clamping structure, low changeover efficiency, and inability to meet the clamping needs of different types of radiators" in the prior art.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a clamping structure for a radiator inspection loading and unloading machine, comprising a housing, a drive mechanism fixedly connected to the right side of the housing, a bidirectional lead screw rotatably connected to the lower inner wall of the housing, the right side of the bidirectional lead screw being connected to the drive mechanism, two sets of sliders mounted on the outer side of the bidirectional lead screw via threaded sleeves, an mounting plate mounted on the lower part of the sliders via an adjustment assembly, a contact plate inserted into the outer side of the mounting plate, a mounting bracket fixedly mounted on the side of the mounting plate away from the contact plate, and a vacuum suction cup fixedly mounted on the outer side of the mounting bracket;

[0007] The adjusting component includes a connecting seat fixedly connected to the lower part of the slider. A connecting member is rotatably connected to the inner wall of the connecting seat. The lower part of the connecting member is fixedly connected to the upper inner wall of the mounting plate. A fixing member is fixedly installed on the upper part of the mounting plate. A pushing member is arranged inside the fixing member. A plug rod is fixedly connected to the outside of the pushing member. The pushing member is elastically connected to the fixing member through a spring. A slot is formed in the lower part of the connecting seat, and the plug rod is inserted into the inner wall of the slot.

[0008] As a further description of the above technical solution:

[0009] A plurality of the pushing members are provided, and two adjacent pushing members are arranged to slide up and down staggeredly.

[0010] As a further description of the above technical solution:

[0011] The pushing member is arranged in a square shape.

[0012] As a further description of the above technical solution:

[0013] The contact plate is arranged in an L shape, and anti-slip patterns are provided on the outside of the contact plate.

[0014] As a further description of the above technical solution:

[0015] The mounting frame is arranged in a U shape. [[ID=2,6]]

[0016] As a further description of the above technical solution:

[0017] A plurality of vacuum suction cups are provided, and the plurality of vacuum suction cups are evenly arranged on the outside of the mounting frame.

[0018] As a further description of the above technical solution:

[0020] The utility model has the following beneficial effects:

[0021] 1. In the utility model, through the combined use of the adjusting component, the vacuum suction cup and the contact plate, when detecting and clamping radiators of different models, by pressing two pushing members, the limit on the mounting plate can be quickly released.

[0022] 2. In the utility model, a plurality of pushing members are provided and are distributed up and down staggeredly. It is necessary to press them simultaneously to release the limit, avoiding accidental rotation caused by single-group accidental touch. After rotation in place, the plug rod is automatically locked under the action of the spring. Description of the Drawings

[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0030] Reference Figures 1-3 This utility model provides an embodiment of a radiator inspection loading and unloading clamping structure, including a housing 1, which serves as the main frame of the entire clamping structure and is used to mount on a robotic arm. A drive mechanism 2 is fixedly connected to the right side of the housing 1, consisting of a servo motor, two sets of transmission wheels, and a synchronous belt. The transmission wheels are fixedly connected to the outside of a bidirectional lead screw 3, providing power for the rotation of the bidirectional lead screw 3. The bidirectional lead screw 3 is rotatably connected to the lower inner wall of the housing 1, converting the rotational motion of the drive mechanism 2 into the linear motion of the slider 4. Through the bidirectional thread design, the two sets of sliders 4 move synchronously towards or away from each other, realizing automatic adjustment of the clamping width. The right side of the bidirectional lead screw 3 is connected to the drive mechanism 2. Two sets of sliders 4 are installed on the outside of the bidirectional lead screw 3 through threaded sleeves, sliding along the lower inner wall of the housing 1 as the bidirectional lead screw 3 rotates, driving the adjustment component 5 and the mounting plate 6 to move, thereby realizing the opening and closing of the clamping mechanism.

[0031] Reference Figures 1-3The lower part of the slider 4 is equipped with a mounting plate 6 via an adjustment component 5. The adjustment component 5 is used to connect the slider 4 and the mounting plate 6 to realize the angle adjustment and locking of the mounting plate 6. A contact plate 7 is inserted into the outside of the mounting plate 6, which directly contacts the heat sink and fixes the workpiece by clamping force. It is suitable for clamping heavy heat sinks. A mounting bracket 8 is fixedly installed on the side of the mounting plate 6 away from the contact plate 7. The mounting bracket 8 is U-shaped to support the layout and adsorption function of the vacuum suction cup 9. A vacuum suction cup 9 is fixedly installed on the outside of the mounting bracket 8, which is connected to an external vacuum air source. It adsorbs the heat sink by vacuum negative pressure and is suitable for non-contact clamping of thin heat sinks, avoiding deformation caused by rigid clamping.

[0032] Reference Figures 2-4 The adjusting component 5 includes a connecting seat 51 fixedly connected to the lower part of the slider 4 for supporting the connecting piece 57. The connecting piece 57 is rotatably connected to the inner wall of the connecting seat 51 for connecting the slider 4 and the mounting plate 6. The lower part of the connecting piece 57 is fixedly connected to the upper inner wall of the mounting plate 6. The connecting piece 57 and the mounting plate 6 are fixed by bolts. A fixing piece 52 is fixedly installed on the upper part of the mounting plate 6. The fixing piece 52 and the mounting plate 6 are fixed by bolts to provide movement space for the pushing piece 53. The inner wall of the fixing piece 52 is provided with the pushing piece 53. Multiple sets of pushing pieces 53 are provided. Adjacent sets of pushing pieces 53 are arranged alternately up and down. The pushing piece 53 is shaped like a "U". When pressed, it drives the insertion rod 54 to disengage from the slot 56 and releases the restriction on the mounting plate 6. Multiple sets are arranged alternately up and down. They need to be pressed simultaneously to avoid accidental contact.

[0033] Reference Figures 2-4 The pusher 53 is fixedly connected to the outside of the insert rod 54. The pusher 53 is elastically connected to the fixing member 52 through the spring 55. The elastic force of the spring 55 makes the insert rod 54 stably inserted into the inner wall of the slot 56. The lower part of the connecting seat 51 has a slot 56. The insert rod 54 is inserted into the inner wall of the slot 56. The slot 56 and the insert rod 54 are engaged to lock the rotation angle of the mounting plate 6. The contact plate 7 is set in L shape and the outer side of the contact plate 7 is provided with anti-slip texture to increase friction and prevent the radiator from slipping. It is especially suitable for smooth metal materials. Multiple sets of vacuum suction cups 9 are provided. Multiple sets of vacuum suction cups 9 are evenly arranged on the outside of the mounting bracket 8. They are made of wear-resistant rubber to adapt to radiators with different surface roughness and ensure sealing performance. The pusher 53 slides through the inner wall of the fixing member 52.

[0034] Working principle: When in use, after the drive mechanism 2 is started, it drives the bidirectional lead screw 3 to rotate clockwise or counterclockwise through the transmission wheel and the synchronous belt. The slider 4 is connected to the bidirectional lead screw 3 through the threaded sleeve and slides horizontally along the lower inner wall of the outer shell 1 as the lead screw rotates, driving the mounting plate 6, contact plate 7 and vacuum suction cup 9 to move synchronously.

[0035] During operation, the robotic arm drives the gripping structure to descend, and the L-shaped structure of the contact plate 7 contacts the heat sink from the side and bottom. The drive mechanism 2 controls the bidirectional lead screw 3 to retract, and the contact plate 7 clamps the workpiece through the anti-slip texture.

[0036] When adjustment is required, press both sets of pushers 53. The insert 54 on the outside of the pusher 53 overcomes the spring force of the spring 55 and exits from the slot 56 of the connector 51, releasing the restriction on the mounting plate 6. Multiple sets of pushers 53 must be pressed simultaneously to avoid accidental activation of a single set, thus improving operational safety.

[0037] Supported by connector 57, mounting plate 6 rotates 180° around connector 51, causing vacuum suction cup 9 and contact plate 7 to switch positions. After releasing pusher 53, spring 55 returns to its original position, and insert rod 54 automatically inserts into new slot 56, forming a mechanical lock to fix the switched position of mounting plate 6.

[0038] At this point, the robotic arm lowers the gripping structure, and the vacuum suction cup 9 comes into close contact with the surface of the radiator; the vacuum source is activated, and multiple sets of vacuum suction cups 9 form a negative pressure of 0.08MPa to adsorb the workpiece. The contact plate 7 does not apply clamping force and only serves as an auxiliary support; the robotic arm is lifted to complete the non-contact gripping of the thin part, with a deformation of ≤0.03mm.

[0039] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
