Description

[Technical field]

[0001] The invention belongs to the technical field of rubber coating equipment, and in particular relates to automatic rubber coating equipment and a rubber coating method for heat sink products. [Background technology]

[0002] A heat sink is a device for dissipating heat from heat-prone electronic components in electrical appliances. It is mostly made of aluminum alloy, brass or bronze in the form of plates, sheets, multiple sheets, etc. For example, a CPU in a computer requires a relatively large heat sink, and power tubes, line tubes, and power amplifier tubes in a TV all require heat sinks. After the heat sink is manufactured, multiple layers of tape need to be wrapped around the outer surface to protect the surface of the heat sink. The traditional operation is to manually wrap the outer periphery of the heat sink with glue, which is inefficient. Patent CN211644091U in the prior art discloses a heat sink wrapping mechanism, which uses a rotating clamping mechanism to clamp one end of the heat sink and rotate the heat sink. A tape feeding mechanism and a tape cutting mechanism are provided on the input side of the rotating clamping mechanism. The tape feeder is pushed to the top of the heat sink by the tape feeding mechanism. A downward pressure cylinder is also provided above the heat sink. The tape feeder is pasted to the surface of the heat sink by the downward pressure cylinder, and then the heat sink is rotated to complete the automatic wrapping. However, the mechanism has the following disadvantages:

[0003] (1) After the tape cutting mechanism cuts the tape, the tape head may adhere to the cutter. The tape itself is made of flexible material. If the tape transmission device in the middle of the tape conveyor is used to push the tape forward, the tape head may not be pushed to the designated position effectively and reliably. The subsequent tape head cannot be attached to the heat sink, resulting in the risk of laminating failure.

[0004] (2) The heat sink only relies on the rotating clamping mechanism to clamp one end of the heat sink for rotation. Since the heat sink itself is a sheet structure, it is easy to be deformed by the pull of the tape during the rubber coating process, and there is a risk of damage to the heat sink. In addition, since the heat sink is in a cantilevered state, there is a risk of the heat sink being deformed when the downward pressure cylinder above the heat sink presses the tape head down to the surface of the heat sink.

[0005] Therefore, it is necessary to provide a new automatic encapsulation equipment and encapsulation method for heat sink products to solve the above technical problems. [Summary of the invention]

[0006] One of the main purposes of the present invention is to provide an automatic encapsulation equipment for heat sink products, which greatly improves the reliability and stability of the automatic encapsulation process of the heat sink and reduces the risk of heat sink deformation.

[0007] The present invention achieves the above-mentioned purpose through the following technical scheme: an automatic encapsulation equipment for heat sink products, comprising:

[Specific implementation method]

[0042] Embodiment 1:

[0043] Please refer to Figure 1-Figure 6 The present embodiment is an automatic adhesive coating device 100 for heat sink products, which is mainly used to wrap multiple layers of adhesive tape on a set section of a heat sink 200 to realize the automatic adhesive coating operation of the heat sink. The present embodiment is an automatic adhesive coating device and adhesive coating method 100 for heat sink products, including an adhesive tape feeding module 1, a rotating clamping module 2 for clamping the heat sink 200 for rotational movement, and an adhesive tape feeding module 3 for realizing the adsorption and pasting of the adhesive tape head and the cutting of the adhesive tape tail.

[0044] The tape feeding module 1 adopts a conventional tape feeding mechanism in the prior art, including a tape feeding reel assembly, a feeding roller assembly, a tension control assembly, and a tape guide roller assembly.

[0045] The rotating clamping module 2 includes a support 21, a first clamp 22 and a second clamp 23 arranged on the support 21 in a front-to-back manner, a driving assembly 24 driving the first clamp 22 and the second clamp 23 to rotate synchronously, and a first cylinder 25 driving the first clamp 22 to telescope forward and backward. The first clamp 22 includes a rotating cylinder 221, a telescopic rod 222 axially movable through the rotating cylinder 221, and a top holding block 223 fixed at the end of the telescopic rod 222. The first cylinder 25 drives the telescopic rod 22 to telescope axially. The second clamp 23 and the rotating cylinder 221 are both rotatably arranged on the support 21 through bearings.

[0046] The second clamp 23 is provided with a limiting slot 231 for facilitating the placement of the heat sink 200 and limiting the position of the placed heat sink. The limiting slot 231 is formed with an opening on the outer peripheral surface of the second clamp 23, which allows the heat sink 200 to be placed in the opening on one hand, and allows the extended section of the heat sink 200 to extend out of the second clamp 23 body on the other hand.

[0047] In this embodiment, the heat sink 200 is an L-shaped thin sheet structure, so the cross-sectional shape of the limiting slot 231 is also designed to be L-shaped. In other embodiments, if the heat sink 200 is a horizontal sheet structure, the limiting slot 231 can be designed to be a slot structure extending horizontally. The cross-sectional shape of the limiting slot 231 is roughly similar to the overall shape of the heat sink.

[0048] The first cylinder 25 is fixed on the support 21 and is located at the front axial end of the telescopic rod 222. Its piston end is connected to the end of the telescopic rod 222, driving the telescopic rod 222 to perform axial telescopic movement relative to the rotating cylinder 221, thereby driving the supporting block 223 to move axially.

[0049] In order to make the telescopic rod 222 and the rotating cylinder 221 rotate synchronously, the telescopic rod 222 and the rotating cylinder 221 are connected together by a pin shaft 224, and the pin shaft 224 radially passes through the telescopic rod 222 and the rotating cylinder 221. When the rotating cylinder 221 rotates, the telescopic rod 222 is rotated together through the pin shaft 224. The outer peripheral surface of the rotating cylinder 221 is provided with an avoidance strip groove 2211 for the axial movement of the pin shaft 224, and the pin shaft 224 extends into the avoidance strip groove 2211.

[0050] In the present embodiment, when the heat sink 200 is coated with rubber, the tape needs to cover a certain distance outside the free end of the heat sink 200, and the tape needs to be completely in contact with the outer peripheral surface of the set section of the heat sink 200. Therefore, the supporting block 223 can only support the front end side surface of the heat sink 200, and the U-shaped slot structure cannot be used to clamp the free end of the heat sink 200. Otherwise, the tape will entangle the U-shaped slot structure with the front end of the heat sink 200, making it difficult to cut the heat sink after subsequent rubber coating.

[0051] In other embodiments, if the front free end of the heat sink 200 does not need to be covered with tape, a U-shaped slot structure can be designed on the top holding block 223 to clamp and limit the free end of the heat sink 200.

[0052] After the heat sink 200 is installed on the second chuck 23, its front end is cantilevered outside. Due to the thin sheet structure of the heat sink 200, its incoming material may be deformed to a certain extent, resulting in the inability of the supporting block 223 to accurately support the front end surface of the heat sink after it is extended. In order to solve this technical problem, the rotary clamping module 2 of this embodiment also includes a correction module 26 for correcting the position of the front end of the heat sink. The correction module 26 includes a second cylinder 261 fixed on the support 21, a mounting plate 262 driven by the second cylinder 261 to move forward and backward, and a correction cylinder block 263 fixed on the mounting plate 262. A correction slot 2631 is provided on the outer end surface of the correction cylinder block 263, and the supporting block 223 passes through the inside of the correction cylinder block 263. The shape of the correction slot 2631 is similar to the Y-shape in the lying state. The opening size of the free end is large so that it can cover the heat sink with a larger degree of deformation. The height of the axially inward slot is small so that the front end of the heat sink can be corrected to the set height range to ensure that the supporting block 223 can be accurately supported.

[0053] The driving assembly 24 includes a motor 241 fixed on the support 21, a transmission shaft 242 driven by the motor 241 to rotate, a first synchronous pulley 243 fixed on the outer periphery of the rotating cylinder 221, a second synchronous pulley 244 fixed on the outer periphery of the second chuck 22, and a third synchronous pulley 245 and a fourth synchronous pulley 246 fixed on the transmission shaft 242; the first synchronous pulley 243 and the third synchronous pulley 245 are connected to realize synchronous rotation through a synchronous belt transmission; the second synchronous pulley 244 and the fourth synchronous pulley 246 are connected to realize synchronous rotation through a synchronous belt transmission. The transmission shaft 242 is rotatably arranged on the support 21 and extends in the front-rear direction.

[0054] The tape feeding module 3 includes a third cylinder 31 fixed on the support 21, a first support plate 32 driven by the third cylinder 31 to move up and down, a fourth cylinder 33 fixed on the first support plate 32, a second support plate 34 driven by the fourth cylinder 33 to move left and right, a clamping component 35 fixed on the second support plate 34 and arranged in sequence along the tape conveying direction, a material head adsorption and pasting component 36 and a material tail cutting component 37.

[0055] The material clamping assembly 35 includes a fifth cylinder 351 fixed on the second support plate 34 and a material clamping rod 352 driven by the fifth cylinder 351 to move up and down.

[0056] The material head adsorption and pasting assembly 36 includes a sixth cylinder 361 fixed on the second support plate 34 , a third support plate 362 driven by the sixth cylinder 361 to move up and down, and an adsorption block 363 fixed on the third support plate 362 .

[0057] Generally, to achieve the clamping of the tape, two clamping rods 352 are required to perform opening and closing actions. Therefore, the clamping rods 352 need to be arranged in pairs and equipped with clamping claw cylinders. In order to save the number of cylinders and under the premise of limited space, this embodiment uses the up and down movement achieved by the sixth cylinder 361 in the material head adsorption and pasting assembly 36, and sets another clamping rod structure on the third support plate 362. Specifically, the third support plate 362 is provided with a clamping block 353 that cooperates with the clamping rod 352 to achieve the clamping of the tape, and the clamping block 353 is provided with a contoured groove 3531 that cooperates with the clamping rod 352. When the clamping rod 352 moves relative to the clamping block 353 into the contoured groove 3531, the tape can be clamped, otherwise, the clamping is released.

[0058] The tail cutting assembly 37 includes a seventh cylinder 371 fixed on the second support plate 34 and a cutter 372 driven by the seventh cylinder 371 to move up and down.

[0059] When the tape feeding module 3 is working, the third cylinder 31 can realize the overall up and down movement of the clamping component 35, the material head adsorption and pasting component 36 and the material tail cutting component 37, and the fourth cylinder 33 can realize the horizontal transfer movement of the clamping component 35, the material head adsorption and pasting component 36 and the material tail cutting component 37, so that they can be moved to the set horizontal position according to the process requirements to realize their functions.

[0060] This embodiment also provides a method for automatically encapsulating a heat sink product, which includes the following steps:

[0061] S1. In the initial state, the limiting slot 231 is in a horizontal state, the material clamping component 35 is in a tape clamping state, and the material head adsorption and pasting component 36 adsorbs the tape material head; the operator or the manipulator puts the heat sink 200 in a horizontal state into the limiting slot 231 in the second clamping head 23, and the rear end of the heat sink 200 is clamped and limited by the second clamping head 23;

[0062] S2, the second cylinder 261 in the correction module 26 drives the correction cylinder block 263 to extend, and under the correction action of the correction slot 2631, the front end of the heat sink 200 is corrected to the set height position, and at the same time, it is pushed backward into place;

[0063] S3, the first cylinder 25 drives the telescopic rod 222 to extend, the holding block 223 holds the front end surface of the heat sink 200 backward, and the return cylinder block 263 is withdrawn;

[0064] S4, the fourth cylinder 33 drives the material head adsorption and pasting component 36 to adsorb the tape material head and move it horizontally to the top of the heat sink 200, and paste the tape material head onto the surface of the heat sink 200 in a horizontal state, and the driving component 24 drives the first clamp 22 and the second clamp 23 to start rotating with the heat sink 200 to perform automatic glue coating operation, and when the number of tape windings reaches the set value, the heat sink 200 stops rotating and stays in an upright state;

[0065] S5, the adsorption block 363 in the material head adsorption and pasting assembly 36 is lowered to a low position to adsorb the tape; the clamping rod 352 in the clamping assembly 35 moves upward to cooperate with the clamping block 353 to clamp the tape; the cutter 372 in the material tail cutting assembly 37 moves downward to cut off the tape on the heat sink, and at the same time, a new tape material head is formed on the adsorption block 363;

[0066] S6, the second chuck 23 rotates back to the horizontal state, the holding block 223 is withdrawn, and the heat sink wrapped with tape is taken out from the second chuck 23 to realize unloading, and the heat sink is wrapped with tape.

[0067] For those skilled in the art, several modifications and improvements can be made without departing from the inventive concept of the present invention, all of which fall within the protection scope of the present invention.
