Description

Technical Field

[0001] This utility model relates to a heat sink assembly device, specifically a wave plate feeding mechanism for a heat sink assembly device. Background Technology

[0002] There are many types of heat dissipation plate structures for existing automotive EGR coolers, one of which is a corrugated heat dissipation plate. This corrugated heat dissipation plate is composed of an outer annular fixing sleeve and a corrugated plate located inside the annular fixing sleeve. During manufacturing, the fixing sleeve and the corrugated plate are processed independently, and then assembled to form a complete corrugated heat dissipation plate.

[0003] Patent CN202123114753.X discloses an assembly device for a corrugated heat sink, specifically disclosing an automatic feeding and unloading mechanism for the fixing sleeve. However, it does not provide a corresponding solution for feeding the corrugated plate. In existing processing equipment, the corrugated plate is generally fed by a pusher plate with a reciprocating power source. However, the pusher plate only holds the tail end of the corrugated plate, which often causes the corrugated plate to deviate during feeding. This means that the centering of the corrugated plate cannot be guaranteed, resulting in the corrugated plate failing to accurately enter the rectangular feed port of the stop block, leading to feeding failure. This not only damages the corrugated plate but also seriously affects the assembly efficiency. Utility Model Content

[0004] To address the aforementioned problems, this utility model relates to a corrugated plate feeding mechanism for a heat sink assembly equipment. This mechanism ensures the centering of the corrugated plate during the feeding process and guarantees effective docking with the rectangular feed port on the stop block. It features a simple and practical structure and high working efficiency.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A corrugated plate feeding mechanism for a heat sink assembly device includes a working platform for carrying the corrugated plate. The front end of the working platform corresponds to a rectangular feed port on a fixed sleeve stop block. A reciprocating power source is provided at the rear of the working platform. A push plate is provided at the front end of the reciprocating power source. The action of the reciprocating power source causes the push plate to move forward and push the corrugated plate on the working platform to the rectangular feed port. The characteristic feature is that a guide pin is provided on each side of the front end of the push plate, and the width between the guide pins is not less than the width of the corrugated plate.

[0007] More specifically, the length of the aforementioned guide pin is not less than the total length of the wave plate.

[0008] More specifically, the top outer side of the aforementioned guide pin is provided with a chamfered bevel.

[0009] More specifically, the inner surface of the aforementioned guide pin is configured as a straight plane.

[0010] More specifically, the aforementioned work platform includes a loading platform, and a limiting block is provided on each side of the loading platform, with the inner side of the limiting block closely attached to the guide pin.

[0011] More specifically, one of the two limiting blocks is configured as a movable clamping block structure, and an adjusting block is provided below the limiting block. The adjusting block is provided with a telescopic cylinder, hydraulic cylinder or adjusting screw that can drive it to move inward and outward.

[0012] More specifically, the aforementioned reciprocating power source includes a linear guide rail, on which a slide plate is mounted. The bottom of the slide plate is connected to a lead screw via a slider, and the rear end of the lead screw is connected to a drive motor.

[0013] More specifically, the aforementioned reciprocating power source is a cylinder or a hydraulic cylinder.

[0014] More specifically, the gap between the two limiting blocks forms a guide groove for the wave plate to be fed, and a pressure plate is provided above one of the limiting blocks in the guide groove.

[0015] The push plate designed in this utility model has a guide pin on each of its two front sides. The two guide pins move forward synchronously with the push plate. During the process of pushing the corrugated plate to feed, the two guide pins always clamp the two sides of the corrugated plate, which can effectively limit and fix the corrugated plate and ensure the centering of the corrugated plate feeding. This process continues until the entire corrugated plate is inserted into the rectangular feed port and completely fed into the fixed sleeve. After that, the two guide pins move back to the initial position with the reset of the push plate, preparing for the next feeding of the corrugated plate. Attached Figure Description

Detailed Implementation

[0020] like Figure 1-3 As shown, a corrugated plate feeding mechanism of a heat sink assembly equipment includes a working platform 1 for carrying the corrugated plate 2.

[0021] The work platform 1 includes a loading plate 11. A limiting block 12 is provided on each side of the loading plate 11. The inner side of the limiting block 12 is a straight limiting surface 121. The gap between the two limiting blocks 12 forms a guide groove 13 for the wave plate 2 to be fed. A pressure plate 14 is provided above one of the limiting blocks 12 in the guide groove 13 to realize the vertical limiting of the wave plate 2.

[0022] The front end of the working platform 1 corresponds to the rectangular feed port 31 on the fixed sleeve stop block 3, so that the guide groove 13 and the rectangular feed port 31 are arranged in a straight line.

[0023] A reciprocating power source 4 is provided at the rear of the working platform 1. A push plate 5 is provided at the front end of the reciprocating power source 4 via a connecting plate 4a. The action of the reciprocating power source 4 causes the push plate 5 to move forward and push the wave plate 2 on the working platform 1 to the rectangular feed port 31 to complete the feeding operation.

[0024] In this diagram, the reciprocating power source 4 includes a linear guide rail 41. A sliding plate 42 is fixedly connected to the linear guide rail 41 via a connecting plate 4a. The bottom of the sliding plate 42 is connected to a lead screw 43 via a slider. The rear end of the lead screw 43 is connected to a drive motor 44. During operation, the drive motor 44 drives the lead screw 43 to rotate in both forward and reverse directions to achieve the forward feeding and backward resetting of the sliding plate 42 on the linear guide rail 41, and ultimately achieve the feeding and backward resetting of the push plate 5.

[0025] The connecting plate 4a is provided with several horizontal elongated holes 4a1. The horizontal elongated holes 4a1 are fixed to the slide plate 42 by screws. During use, the horizontal position of the connecting plate 4a can be adjusted by adjusting the position of the horizontal elongated holes 4a1.

[0026] In practice, the reciprocating power source 4 can also be replaced by a cylinder or hydraulic cylinder structure, as long as it can realize the reciprocating back and forth movement of the push plate 4.

[0027] The push plate 5 has a guide pin 51 on each side of its front end. The length of the guide pin 51 is not less than the total length of the wave plate 2, and the width between the guide pins 51 is not less than the width of the wave plate 2. The outer side of the guide pin 51 is in close contact with the straight limiting surface 121 of the corresponding limiting block 12, and the inner side of the guide pin 51 is set as a straight plane 512 to effectively ensure the contact surface between it and the wave plate 2 and enhance its limiting and guiding effect on the wave plate 2.

[0028] During operation, the two guide pins 51 move forward synchronously with the push plate 5. During the feeding process of the corrugated plate 2, the two guide pins 51 always clamp the two sides of the corrugated plate 2, which provides good limiting and fixing for the corrugated plate 2 and ensures the centering of the feeding of the corrugated plate 2. This process continues until the entire corrugated plate 2 is inserted into the rectangular feed port 31 and completely fed into the fixed sleeve. After that, the two guide pins 51 move backward and are pulled out with the reset of the push plate 5, returning to the initial position, preparing for the next feeding of the corrugated plate 2.

[0029] The guide pin 51 has a chamfered bevel 511 on its top outer side. The chamfered bevel 511 serves to guide and gather the two guide pins 51, ensuring that they can be smoothly inserted into the rectangular feed port 31.

[0030] In addition, to meet the processing needs of corrugated plates of different widths, one of the two limiting blocks 12 on the carrier plate 11 is configured as a movable clamping block structure. An adjusting block 122 is provided below the limiting block. The adjusting block 122 is equipped with a telescopic cylinder, hydraulic cylinder or adjusting screw 123 that can drive it to move inward and outward. In practice, the position of the limiting block is adjusted by this telescopic structure, thereby realizing the adjustment of the guide groove width between the two limiting blocks 12 to meet the processing needs of corrugated plates 2 of different widths.

[0031] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the utility model in any way. Any simple modifications, equivalent changes, or alterations made to the above embodiments based on the technical principles of the present utility model shall still fall within the scope of the technical solution of the present utility model.
