Description

Technical Field

[0001] The present invention relates to the technical field of assembly for heat spreader production, and in particular to an online electroplating product and carrier assembly production line. Background Art

[0002] With the progress of science and technology and the development of economy and society, various electronic products have emerged. The faster the computing and processing speed of electronic products, the more they can win the favor of consumers. The fast processing speed also requires electronic products to use high-power electronic components. High-power electronic components will also generate more heat during operation. If the heat generated by the electronic components cannot be dissipated in time, the electronic components will be damaged due to excessive temperature, and then the electronic products will be damaged.

[0003] Currently, most of the heat spreaders are assembled on electronic components. During the production process of the heat spreader, several heat spreaders need to be supported by material strips to facilitate the transportation of the heat spreader. During the assembly process of the heat spreader and the material strip, a driving structure needs to be used to drive the material strip to intermittently feed, and the heat spreader is installed through intermittent intervals.

[0004] The prior art discloses a patent with announcement number CN209658137U, the scheme includes: a workbench and a transmission mechanism, a feeding mechanism, a grabbing mechanism, and a pressing mechanism installed on the workbench, wherein the transmission mechanism includes an input end and an output end, a heat sink crystal is provided on the transmission mechanism, a magnetic bead is provided on the feeding mechanism, the feeding mechanism, the grabbing mechanism, and the pressing mechanism are arranged along the transmission mechanism, the feeding mechanism and the grabbing mechanism are arranged oppositely and close to the input end of the transmission mechanism, and the pressing mechanism is close to the output end of the transmission mechanism. The present application provides a heat sink crystal set magnetic bead device machine heat sink assembly machine, which solves the technical problem of low efficiency of manual magnetic bead setting in the prior art.

[0005] As the existing devices are used, the shortcomings of the technology are gradually exposed, mainly in the following aspects:

[0006] First, when assembling products on the existing material belt, due to the need to carry out different processing steps, the equipment is not arranged in the same longitudinal direction, which makes it difficult to support the material belt at the corner position, affecting the stability of the material belt during feeding.

[0007] Second, when the material tape is fed to the assembly machine, the assembly machine feeds the material tape at intervals for assembling the product. Since the material tape unwinding process is ongoing, the material tape is prone to being unwound too long, which in turn affects the stability of the material tape feeding.

[0008] Third, the existing grabbing tooling grabs the heat spreader from the material tray and directly installs it into the material belt. Due to the low positioning accuracy of the product in the material tray, products at different positions often interfere with the material belt when they are assembled with the material belt, resulting in the inability to quickly assemble the product to the material belt, affecting the assembly efficiency.

[0009] Fourth, the existing material belt cannot accurately locate the movement stroke and position of the material belt during the product assembly process, resulting in the material belt and the product being unable to achieve accurate matching and installation during the assembly process, thereby reducing the assembly efficiency of the product.

[0010] Fifth, the existing device cannot be adjusted according to the width of different material strips, so it needs to be customized according to different material strips, which reduces the scope of use.

[0011] Sixth, the existing material strip is prone to displacement during the opening process, which in turn affects the stability of the heat spreader during assembly.

[0012] As can be seen from the above, the existing technology obviously has inconveniences and defects in practical use, so it is necessary to improve it. Summary of the invention

[0057] Compared with the prior art, the present invention has the following beneficial effects:

[0058] The material belt is fed through the material belt pulling area of ​​the front-end power pulling device and the rear-end power pulling module. The material belt passing through the corner passes through the material belt support plates or material belt rollers on several guide racks in sequence. When the subsequent assembly machine feeds the material belt intermittently, the material belt will deviate at the corner position. The guide rack slides on the slide rail to assist the material belt in deviating, ensuring that the material belt can still be supported during the deviating process.

[0059] The guide frame slides on the slide rail to change the relative position of the material belt and the buffer rack to achieve the buffer function. Two position sensors detect the front and rear positions of the material belt. The PLC signal monitors the position of the material belt and controls the movement of the front and rear machines.

[0060] By adjusting the rotation of the bearing, the offset angle between the material belt support plate and the material belt is consistent to prevent the material belt from getting stuck;

[0061] The buffer margin can be adjusted by adjusting the forward and backward movement of the slide rail, and the difference between inching and continuous movement can be achieved through margin control;

[0062] This mechanism solves the difference between inch motion and continuous motion and realizes the feasibility of the motion mode for online assembly of products.

[0063] The position of the material strip is monitored by the position sensor, and the actions of the front and rear machines are coordinated synchronously to achieve the feasibility of electroplating without stopping.

[0064] By placing the tray on the linear slide rail, the product can be supplied. Through the transfer precision positioning, the loading action is split into two steps, overcoming the influence of low precision of the product in the tray. Regardless of the positioning accuracy of the product in the tray, the intermediate positioning module will achieve secondary precision positioning, and then the loading module will be used to grab the precisely positioned product into the material belt to improve the working efficiency.

[0065] The product can be flipped to a suitable angle matching the material belt by the flip cylinder, and the assembly of materials at different angles can be completed;

[0066] The gripper uses a nitrile rubber protective cover to effectively protect the product, overcoming the problem of silicone oil seeping out of the product surface after the silicone protective cover is clamped, causing product contamination;

[0067] The opening mechanism is designed to be split into left and right parts, installed on the spacing adjustment rail, and the spacing is adjusted by the spacing adjustment screws to achieve the versatility of strips of different widths;

[0068] Before opening the spring clip of the material belt, first use the material belt pressing block to press and fix the material belt to prevent the material belt from deforming and scratching the product during the lifting process;

[0069] Before placing the product, lift the material pallet and limit the bottom of the product to prevent the product from moving downward during placement and causing scratches.

[0070] The top cylinder is used to lift the top head to lift the spring sheet on the material belt. After the material belt is lifted, the spring sheet opens to avoid the product in the up and down directions, meeting the material placement conditions;

[0071] The material strip moves toward the pressing wheel along the positioning plate and the pulling frame. When material pulling is required, the pulling guide seat drives the pulling plate to move along the pulling guide rail to a position close to the pressing plate, and then the pulling cylinder extends, driving the pulling needle to extend and inserting the pulling needle into the pulling hole of the material strip. Then the pulling guide seat drives the pulling plate and the material strip to move toward the pressing wheel to realize the material pulling work. When it moves into place, the positioning cylinder drives the positioning needle to slide, and the positioning needle is inserted into the positioning hole of the material strip. After the material strip is positioned, the pulling needle withdraws from the material strip under the action of the pulling cylinder and returns to the starting position. The above steps are repeated for the next material pulling action. Among them, the positioning needle does not contact the material strip only during the process of the material strip being driven by the pulling needle, and is inserted into the positioning hole of the material strip for positioning at the rest of the time, thereby realizing precise material pulling movement and positioning, and improving the stability of the material strip and product assembly process.

[0130] The two ends of the material pulling frame 56 corresponding to the material pressing wheel 46 are respectively fixedly connected with a frame body, and the two ends of the material pressing wheel 46 are rotatably installed in the frame body by using a rotating shaft.

[0131] A guide rod is fixedly connected to the inner wall of the positioning plate 59, and a guide hole matching the guide rod is opened on the material pulling rack 56.

[0132] The working principle of this device is:

[0133] The material belt is fed through the material belt pulling area of ​​the head-end power pulling device 78 and the end-end power pulling module 82. The material belt passing through the corner passes through the material belt support plates 74 or material belt rollers 72 on the guide frames 77 in sequence. When the subsequent assembly machine feeds the material belt intermittently, the material belt will deviate at the corner position. The guide frame 77 slides on the slide rail 75 to assist the material belt in deviating, ensuring that the material belt can still be supported during the deviating process.

[0134] The guide frame 77 slides on the slide rail 75 to change the relative position of the material belt and the buffer rack 76 to achieve the buffer function. The two position sensors 73 detect the front and rear positions of the material belt, and the PLC signal monitors the position of the material belt to control the movement of the front and rear machines.

[0135] By adjusting the rotation of the bearing 69, the offset angle of the material belt support plate 74 and the material belt is made consistent to prevent the material belt from being stuck;

[0136] The buffer margin is adjusted by adjusting the forward and backward movement of the slide rail 75, and the difference between inching and continuous movement is achieved through margin control;

[0137] This mechanism solves the difference between inch motion and continuous motion and realizes the feasibility of the motion mode for online assembly of products.

[0138] The position of the material belt is monitored by the position sensor 73, and the actions of the front and rear machines are synchronously coordinated to realize the feasibility of non-stop electroplating; the product 16 is supplied by placing the material tray on the linear slide rail, and the feeding action is split into two steps through the transfer precision positioning, which overcomes the influence of the low precision of the product 16 in the material tray. Regardless of the positioning accuracy of the product 16 in the material tray, the secondary precision positioning is realized by the intermediate positioning module 62, and then the precisely positioned product 16 is grabbed into the material belt 37 by the feeding module 63, thereby improving the working efficiency;

[0139] The product 16 can be flipped to a suitable angle matching the material belt 37 by the flipping cylinder 13, so as to complete the assembly of materials at different angles;

[0140] The clamping jaw 15 uses a nitrile rubber protective cover 14 to effectively protect the product 16, and overcomes the problem of silicone oil leakage from the surface of the product 16 after the silicone protective cover is clamped, resulting in contamination of the product 16;

[0141] The opening mechanism is designed to be split into left and right parts, installed on the spacing adjustment rail 30, and the spacing is adjusted by the spacing adjustment screw to achieve the versatility of the material strips 37 of different widths;

[0142] Before opening the spring piece 39 of the material belt 37, first use the material belt pressing block 26 to press and fix the material belt 37 to prevent the material belt 37 from deforming and scratching the product 16 during the process of lifting the material belt 37;

[0143] Before placing the product 16, lift the material support plate 29 to limit the bottom of the product 16 to prevent the product 16 from moving downward during placement and causing scratches on the product 16;

[0144] The top cylinder 35 is used to lift the top head 38 to lift the spring piece 39 on the material belt 37. After the material belt 37 is lifted, the spring piece 39 opens to avoid the product 16 in the upper and lower directions, meeting the material placement conditions;

[0145] The material belt 37 moves along the positioning plate 59 and the material drawing frame 56 toward the material pressing wheel 46. When material drawing is required, the material drawing guide seat 51 drives the material drawing plate 57 to move along the material drawing guide rail 50 to a position close to the material pressing plate. Then the material drawing cylinder 49 extends, driving the material drawing needle 58 to extend and insert the material drawing needle 58 into the material drawing hole of the material belt 37. Then the material drawing guide seat 51 drives the material drawing plate 57 and the material belt 37 to move toward the material pressing wheel 46 to realize the material drawing work. When it moves into place, the positioning cylinder 48 drives the positioning needle 5 to slide. After the positioning needle 5 is inserted into the positioning hole of the material strip 37 to position the material strip 37, the pulling needle 58 withdraws from the material strip 37 under the action of the pulling cylinder 49 and returns to the starting position, and the above steps are repeated to perform the next pulling action. Among them, the positioning needle 5 does not contact the material strip 37 only when the pulling needle 58 drives the material strip 37 to move, and the rest of the time it is inserted into the positioning hole of the material strip 37 for positioning, thereby realizing precise pulling, moving and positioning work, and improving the stability of the material strip 37 and the product 16 during assembly.
