Description
Technical Field
[0001] This invention relates to the field of graphite heat sink production equipment, and in particular to an automatic loading and unloading device for a graphite heat sink pressing machine. Background Technology
[0002] Currently, graphite heat sinks are widely used in the heat dissipation of electronic devices (such as mobile phones and laptops) due to their excellent thermal conductivity. In the production process of graphite heat sinks, graphite blanks (powder or sheet-like pre-pressed blanks) need to be pressed into finished products of specific thickness and shape using a press. Loading and unloading are crucial steps in the pressing process. Currently, the industry mostly uses manual loading and unloading for graphite heat sink presses: workers manually place the blanks to be pressed into the press mold, and then manually remove the finished product after pressing. This method suffers from low efficiency and high labor costs; furthermore, graphite blanks easily generate dust, and long-term exposure can harm workers' health.
[0003] To address the aforementioned technologies, a new automated device is needed to solve the problem. Summary of the Invention
[0004] The purpose of this application is to provide an automatic loading and unloading device for a graphite heat sink pressing machine to solve the problems of low efficiency and high cost of manual loading and unloading.
[0005] The automatic loading and unloading device for a graphite heat sink pressing machine provided in this application adopts the following technical solution: An automatic loading and unloading device for a graphite heat sink pressing machine includes a worktable, and the upper end of the worktable is respectively fixedly provided with a loading device for conveying blanks, a transfer device for carrying blanks and pushing blanks to the next process, a pressing device for pressing blanks, a pushing device for pushing the molded material out of the pressing device, and a unloading device for receiving the molded material. By adopting the above technical solution, the device is divided into five modules: feeding, conveying, pressing, pushing, and unloading. When pressing graphite heat sinks, the feeding device conveys the material, the conveying device transfers the blank and pushes it into the pressing device, the pressing device presses the material, the pushing device unloads the material after pressing, and the unloading device unloads the material. This setup automates the entire process from blank conveying, conveying, pressing to molding and unloading, eliminating the need for manual intervention, reducing labor costs, and avoiding the safety risks that may arise from manual operation.
[0006] Preferably, the feeding device includes two base plates and an electric module. A conveying device is fixedly installed on the upper end of the two base plates. Mounting blocks are fixedly installed at both ends of one side of the conveying device. A through-beam sensor is fixedly installed at one end of each of the two mounting blocks. Both through-beam sensors are through-beam photoelectric sensors. A first mounting plate is fixedly installed on the upper end of the slider connected by a thread inside the electric module. A first cylinder is fixedly installed at one end of the first mounting plate. A first connecting plate is fixedly installed at the output end of the first cylinder. Two functional plates are fixedly installed at one end of the first connecting plate by bolts. One of the base plates is fixedly connected to the worktable. By adopting the above technical solution, the staff places the material to be pressed on the upper end of the conveyor device, which transports it. When the material passes the through-beam sensor, the position is detected, and the external control module controls the first cylinder to descend, which in turn lowers the functional plate. Then, the electric module is activated and controlled to move laterally towards the transfer device, pushing the material to the upper end of the pallet for the next process. The two functional plates have different functions: the one closer to the transfer device acts as a limiter, while the one farther away acts as an assist. Since the transfer device needs to rotate the pallet, a gap is set between the pallet and the conveyor belt of the conveyor device to avoid interference. The material cannot be completely delivered to the upper end of the pallet by the conveyor device alone. Therefore, the material is completely delivered to the upper end of the pallet by the electric module and the assistance of one of the functional plates.
[0007] Preferably, the transfer device includes a mounting frame fixedly mounted on the upper end of a workbench, a servo motor fixedly mounted on the bottom end of the mounting frame, a fixed column fixedly mounted on the output shaft of the servo motor via a coupling, a cross plate fixedly mounted on the upper end of the fixed column, support plates fixedly mounted around the cross plate, a support column fixedly mounted inside the cross plate via bearings, a second cylinder fixedly mounted on the upper end of the support column, a second connecting plate fixedly mounted on the output end of the second cylinder, and a sheet metal part fixedly mounted on one end of the second mounting plate. By adopting the above technical solution, the servo motor drives the cross plate to rotate, and together with the surrounding pallets, realizes the cyclic transfer of materials. When one of the pallets rotates to be closest to and parallel to the pressing device, the second cylinder extends, and the second connecting plate pushes the material onto the feeding plate of the pressing device. Then it continues to rotate, repeating the receiving, transfer and feeding process. At the same time, the second mounting plate is fixed by sheet metal parts to prevent the feeding structure from rotating during rotation, which would affect subsequent operations.
[0008] Preferably, the pressing device includes two support plates fixedly mounted on the upper end of the workbench, a feeding plate fixedly mounted on the upper end of the two support plates, and a plurality of reinforcing ribs fixedly mounted between the feeding plate and the two support plates. The pressing device also includes a pressing structure fixedly mounted on the upper end of the workbench by four columns, one end of the pressing structure being fixedly connected to the end of the sheet metal part away from the second mounting plate. By adopting the above technical solution, the pressing structure is activated to press and shape the material on the feeding plate. The addition of reinforcing ribs enhances the structural strength of the feeding plate, preventing component deformation due to excessive pressure during the pressing process.
[0009] Preferably, the pushing device includes a mounting plate fixed to the upper end of the workbench, an electric push rod is fixedly provided at one end of the mounting plate, and a third connecting plate is fixedly provided at the output end of the electric push rod; By adopting the above technical solution, the third connecting plate can be driven by an electric push rod to push out the molded material that has been pressed in the pressing device.
[0010] Preferably, the feeding device includes a support frame fixedly mounted on the upper end of the workbench, and a sliding plate is fixedly mounted on the upper end of the support frame; By adopting the above technical solution, the molded material is pushed by the pushing device onto the upper end of the sliding plate of the feeding device, thereby realizing the collection of the molded material.
[0011] Preferably, an outer shell is fixedly installed on the upper end of the workbench, a dust collection device is fixedly installed on the upper end of the outer shell, a dust collection pipe is fixedly installed at one end of the dust collection device, and the end of the dust collection pipe away from the dust collection device passes through the outer shell and is fixedly connected to a dust collection head. By adopting the above technical solution, the graphite blank is prone to generating dust. By enclosing the working module with the outer shell, the dust generated in the production process can be isolated. A dust collection device is set up to collect the internal dust in real time through the dust collection pipe and dust collection head, thereby improving the production environment and protecting the health of the operators.
[0012] Preferably, the outer wall of the outer casing near the slide plate has a through opening; By adopting the above technical solution, opening a through-hole on the outer wall of the outer shell near the slide plate can ensure that the molded material slides off the slide plate to the outside, making it convenient for staff to collect. Beneficial effects
[0013] In summary, this application includes at least one of the following beneficial technical effects: 1. This invention provides an automatic loading and unloading device for a graphite heat sink pressing machine. The device is divided into five modules: a loading, a transfer, a pressing, a pushing, and a unloading device. When pressing the graphite heat sink, the loading device transports the material, the transfer device transfers the blank and pushes it into the pressing device, the pressing device presses the material, the pushing device unloads the material after pressing, and the unloading device unloads the material. This setup automates the entire process from blank transportation, transfer, pressing to forming and unloading, eliminating the need for manual intervention, reducing labor costs, and avoiding the safety risks that may arise from manual operation.

[0017] The following is in conjunction with the appendix Figure 1 -Appendix Figure 7 This application will be described in further detail below.
[0018] Example 1: An automatic loading and unloading device for a graphite heat sink pressing machine, referring to... Figure 2 It includes a workbench 1, and the upper end of the workbench 1 is respectively fixedly equipped with a feeding device 2 for conveying blanks, a transfer device 3 for carrying blanks and pushing blanks to the next process, a pressing device 4 for pressing blanks, a pushing device 5 for pushing the molded material out of the pressing device 4, and a discharging device 6 for receiving the molded material.
[0019] The technical advantage of the above-mentioned device is that by setting up five modules in sections, namely the feeding, transfer, pressing, pushing and unloading devices 6, the graphite heat sink is pressed. The feeding device 2 conveys the material, the transfer device 3 transfers the blank and pushes it into the pressing device 4, the pressing device 4 presses it, the pushing device 5 unloads the material after pressing, and the unloading device 6 unloads it. This setup realizes the full automation of the blank conveying, transfer, pressing to forming and unloading, without the need for manual intervention, reducing labor costs and avoiding the safety risks that may be caused by manual operation.
[0020] Example 2: An automatic loading and unloading device for a graphite heat sink pressing machine, referring to... Figure 2 , Figure 3 and Figure 4 The feeding device 2 includes two base plates 201 and an electric module 205. A conveying device 202 is fixedly installed on the upper end of the two base plates 201. Mounting blocks 203 are fixedly installed on both ends of one side of the conveying device 202. A through-beam sensor 204 is fixedly installed on the corresponding end of the two mounting blocks 203. Both through-beam sensors 204 are through-beam photoelectric sensors. A first mounting plate 206 is fixedly installed on the upper end of the slider connected by the internal thread of the electric module 205. A first cylinder 207 is fixedly installed on one end of the first mounting plate 206. A first connecting plate 208 is fixedly installed on the output end of the first cylinder 207. Two functional plates 209 are fixedly fixed on one end of the first connecting plate 208 by bolts. One of the base plates 201 is fixedly connected to the worktable 1.
[0021] The technical effect of the above device is as follows: the operator places the material to be pressed on the upper end of the conveyor 202, which transports it. When the material passes the through-beam sensor 204, the position is detected, and the external control module controls the first cylinder 207 to descend, which in turn causes the functional plate 209 to descend. Then, the electric module 205 is started and controlled to move laterally towards the transfer device 3, pushing the material to the upper end of the pallet 305 for the next process. The two functional plates 209 have different functions: the one closer to the transfer device 3 acts as a limiter, while the one farther away acts as an assist. Since the transfer device 3 needs to rotate the pallet 305, a gap is set between the pallet 305 and the conveyor belt of the conveyor 202 to avoid interference. The material cannot be completely delivered to the upper end of the pallet 305 if it is directly connected to the conveyor 202. Therefore, the material is completely delivered to the upper end of the pallet 305 with the assistance of the electric module 205 and one of the functional plates 209.
[0022] Example 3: An automatic loading and unloading device for a graphite heat sink pressing machine, referring to... Figure 2 and Figure 5 The transfer device 3 includes a mounting frame 301 fixedly mounted on the upper end of the workbench 1. A servo motor 302 is fixedly mounted on the bottom end of the mounting frame 301. A fixed column 303 is fixedly mounted on the output shaft of the servo motor 302 via a coupling. A cross plate 304 is fixedly mounted on the upper end of the fixed column 303. Support plates 305 are fixedly mounted on all four sides of the cross plate 304. A support column 306 is fixedly mounted inside the cross plate 304 via bearings. A second cylinder 308 is fixedly mounted on the upper end of the support column 306. A second connecting plate 309 is fixedly mounted on the output end of the second cylinder 308. A sheet metal part 310 is fixedly mounted on one end of the second mounting plate 307.
[0023] The technical effect of the above device is that the servo motor 302 drives the cross plate 304 to rotate, which, together with the surrounding pallets 305, realizes the cyclic transfer of materials. When one of the pallets 305 rotates to be closest to and parallel to the pressing device 4, the second cylinder 308 extends, and the second connecting plate 309 pushes the material onto the feeding plate 402 of the pressing device 4. Then it continues to rotate, repeating the receiving, transfer and feeding process. At the same time, the second mounting plate 307 is fixed by the sheet metal part 310 to prevent the feeding structure from rotating during rotation, which would affect subsequent operations.
[0024] Example 4: An automatic loading and unloading device for a graphite heat sink pressing machine, referring to... Figure 2 , Figure 6 and Figure 7The pressing device 4 includes two support plates 401 fixedly mounted on the upper end of the workbench 1. A feeding plate 402 is fixedly mounted on the upper end of the two support plates 401. Multiple reinforcing ribs 403 are fixedly mounted between the feeding plate 402 and the two support plates 401. The pressing device 4 also includes a pressing structure 404 fixedly mounted on the upper end of the workbench 1 by four columns. One end of the pressing structure 404 is fixedly connected to the end of the sheet metal part 310 away from the second mounting plate 307. The pushing device 5 includes a mounting plate 501 fixedly mounted on the upper end of the workbench 1. An electric push rod 502 is fixedly mounted on one end of the mounting plate 501. A third connecting plate 503 is fixedly mounted on the output end of the electric push rod 502. The unloading device 6 includes a support frame 601 fixedly mounted on the upper end of the workbench 1. A sliding plate 602 is fixedly mounted on the upper end of the support frame 601.
[0025] The technical effect of the above-mentioned device is as follows: when the pressing structure 404 is activated, the material on the feeding plate 402 is pressed and shaped. The reinforcing ribs 403 enhance the structural strength of the feeding plate 402, preventing deformation of the components due to excessive pressure during the pressing process. The electric push rod 502 drives the third connecting plate 503 to push out the shaped material that has been pressed in the pressing device 4. The shaped material is pushed by the pushing device 5 onto the upper end of the sliding plate 602 of the unloading device 6, realizing the collection of the shaped material.
[0026] Example 5: An automatic loading and unloading device for a graphite heat sink pressing machine, referring to... Figure 1 A housing 7 is fixedly installed on the upper end of the workbench 1. A dust collection device 8 is fixedly installed on the upper end of the housing 7. A dust collection pipe 9 is fixedly installed on one end of the dust collection device 8. The end of the dust collection pipe 9 away from the dust collection device 8 passes through the housing 7 and is fixedly connected to a dust collection head 10. A through-hole is opened on the outer wall of the end of the housing 7 near the slide plate 602.
[0027] The technical effect of the above-mentioned device is that graphite blanks are prone to generating dust. By enclosing the working module through the outer shell 7, the dust generated in the production process can be isolated. A dust collection device 8 is set up to collect the internal dust in real time through the dust collection pipe 9 and the dust collection head 10, which improves the production environment and protects the health of operators. A through-hole is opened on the outer wall of the outer shell 7 near the slide plate 602 to ensure that the molded material slides off the slide plate 602 to the outside, which is convenient for the staff to collect.
[0028] The implementation principle of this application embodiment is as follows: The worker places the material to be pressed on the upper end of the conveyor 202, which transports it. When the material passes the through-beam sensor 204, the position is detected, and the external control module controls the first cylinder 207 to descend, thereby lowering the function plate 209. Then, the control electric module 205 is activated, controlling it to move laterally towards the transfer device 3, pushing the material to the upper end of the pallet 305. After loading is completed, the servo motor 302 drives the cross plate 304 to rotate, allowing the material to continue to be placed on the upper end of subsequent pallets 305, thus cyclically placing the material. The servo motor 302 continues to rotate until the first pallet 305 rotates to be closest to and parallel to the pressing device 4, at which point the rotation stops. The second cylinder 308 extends, and the second connecting plate 309 pushes the material onto the discharge plate 402 of the pressing device 4. Then it continues to rotate, repeating the receiving, transfer and feeding process. When the material is sent to the upper end of the discharge plate 402, the pressing structure 404 is activated to press the material on the discharge plate 402 into shape. After pressing is completed, the pressing structure 404 is reset. At this time, the electric push rod 502 is activated to drive the third connecting plate 503 to push out the shaped material that has been pressed in the pressing device 4. The shaped material is pushed by the pushing device 5 onto the upper end of the slide plate 602 of the unloading device 6, completing the unloading of the shaped material. At the same time as the process, the dust collection device 8 is activated to collect the dust inside in real time through the dust collection pipe 9 and the dust collection head 10.

Identical components are represented by the same reference numerals. Therefore, all equivalent changes made to the structure, shape, and principle of this application should be covered within the scope of protection of this application.
