Description

Technical Field

[0001] This invention specifically relates to a copper-clad laminate stacking device. Background Technology

[0002] Copper-clad laminate, also known as copper clad laminate, is a product made by impregnating wood pulp paper or fiberglass cloth with resin as reinforcing materials, covering one or both sides with copper foil, and then hot-pressing them together. Copper-clad laminate is a fundamental material in the electronics industry, primarily used in the manufacturing of printed circuit boards (PCBs). It is widely used in electronic products such as televisions, radios, computers, and mobile communications, serving as an interconnecting conductor, insulator, and support in PCBs.

[0003] In the production and processing of copper clad laminates (CCLs), the finished CCLs need to be stacked in an orderly manner for convenient subsequent storage, transportation, or further processing. Existing CCL stacking devices have many shortcomings in practical applications. Most require workers to manually transfer the CCLs from the conveyor equipment to the supporting structure of the stacking device. This is not only labor-intensive but also inefficient, making it difficult to meet the needs of large-scale production. Furthermore, when performing physical property testing or subsequent processing on the stacked CCLs, manual transfer of each CCL from the device to the testing or processing equipment is required, further increasing the complexity of the process. Manual transfer can also easily cause scratches on the CCL surface and positioning deviations, affecting product quality. Therefore, this paper proposes a copper clad laminate stacking device to solve the above problems. Summary of the Invention

[0004] To address the shortcomings of existing technologies, this invention proposes a copper clad laminate (CCL) stacking device. This addresses the technical problems mentioned in the background section, where existing CCL stacking devices often require manual transfer of CCLs from conveying equipment to the stacking device. Furthermore, when performing physical property testing or processing on the CCLs on the stacking device, manual transfer of each CCL is required, which significantly increases the labor intensity of workers and reduces work efficiency.

[0009] In a preferred embodiment, the support frame includes: The receiving frame is arranged in multiple sets at intervals, and the receiving frame is equipped with rollers and limiting blocks; The column is provided in multiple sets, each fixedly connected to the side of the multiple sets of receiving frames. Adjacent sets of receiving frames are connected by a locking assembly, which locks the positions of adjacent sets of receiving frames and releases the lock when the lower set of receiving frames contacts the conveyor belt mechanism. A limiting component is provided on the receiving frame to retract only when the receiving frame moves to be flush with the copper-clad laminate conveyor belt.

[0010] In a preferred embodiment, the locking component includes: The first wedge-shaped block is slidably disposed on the column and extends out of the column; A second wedge block is disposed on and opposite to the first wedge block. The length of the second wedge block is less than that of the first wedge block. The second wedge block is slidably engaged on an adjacent set of columns. A first elastic element is disposed between the first wedge block and the inner wall of the column; and A drive frame is mounted on the machine frame, the column is slidably engaged within the drive frame, and the support frame can abut against the end face of the first wedge block when it descends to contact the conveyor belt mechanism.

[0011] In a preferred embodiment, the limiting component includes: The limiting plate is vertically adjustable and is provided on the end face of the receiving frame, and a second drive column is provided at its end; A drive block is slidably disposed on the receiving frame, and one end of the drive block is inclined and extends out of the receiving frame. A second inclined groove is provided on the drive block, and the second drive column is slidably engaged in the second inclined groove. The second elastic element abuts against the inner side of the driving block and the receiving frame; and A baffle is provided on the frame and can abut against the end face of the drive block.

[0012] In a preferred embodiment, the drive mechanism includes: The pusher frame is slidably mounted on the frame, and one end is provided with a push block and a stop block connected by a guide rod. A third elastic element is provided between the stop block and the frame. A push column is provided on the side of the copper-clad laminate conveyor belt and can abut against the push frame; Multiple sets of horizontal tracks are arranged, all located on one side of the column. The endpoints of each horizontal track are connected to the middle section of an adjacent set of horizontal tracks via inclined tracks. A first step and a second step are respectively provided at both ends of the inclined tracks. The mounting frame is mounted on the pusher frame and a guide post is slidably inserted through it. A fourth elastic element is provided between the guide post and the mounting frame, and the guide post is engaged at one end of the flat track.

[0013] In a preferred embodiment, the unloading mechanism includes: A telescopic cylinder is mounted on the frame, and its output end is equipped with a push rod flush with the copper-clad laminate conveyor belt. The receiving frame has a channel for the push rod to be pushed in.

[0015] Compared with the prior art, the present invention has the following beneficial effects: In traditional copper-clad laminate (CCL) stacking operations, workers must continuously shuttle between the conveyor and the stacking device, bending over to pick up CCLs and precisely place them on the support structure. A single operation exceeding half an hour can easily lead to back pain, arm fatigue, and other problems. Furthermore, each worker can only complete the transfer and stacking of approximately 8-10 CCLs per minute. This new device, through its fully automated design, completely replaces the manual handling process. The CCL conveyor mechanism can directly connect to the upstream production conveyor line, automatically receiving and transporting CCLs to designated positions on the support frame. The drive mechanism precisely lowers the support frame at specified intervals, ensuring that each CCL is stacked stably and with proper spacing, effectively protecting the CCL surface. No manual adjustment of spacing or positioning is required. A full support frame can be automatically transferred out of the device via a conveyor belt mechanism, facilitating continuous work and providing space for the upper support frame to descend. By switching the mechanism, the movement of the conveyor belt mechanism can be selectively converted to drive the copper-clad laminate conveying mechanism to convey in both forward and reverse directions. When the copper-clad laminate conveying mechanism is running in reverse, the unloading mechanism automatically completes the unloading of the copper-clad laminate, making it convenient to transfer the copper-clad laminate on the support frame to subsequent processing or inspection equipment. The staff only needs to monitor the start and stop of the device and install the support frame. One person can manage multiple devices at the same time. The stacking efficiency of a single device per hour is effectively improved, reducing the labor intensity of the staff and avoiding the risk of occupational injury caused by long-term repetitive labor.

[0019] The present invention will now be described in further detail with reference to the accompanying drawings. It should be noted that the following specific embodiments are only used to further illustrate the present invention and should not be construed as limiting the scope of protection of the present invention. Those skilled in the art can make some non-essential improvements and adjustments to the present invention based on the above application content.

[0020] Example: like Figure 1 , 3 As shown, the present invention provides a copper clad laminate stacking device, including a frame 1, a mounting frame 16 on the frame 1, multiple sets of stacked support frames 2 arranged inside the mounting frame 16, a baffle 7 on the frame 1, a conveyor belt mechanism 71 for conveying the bottom set of support frames 2 inside the baffle 7, a copper clad laminate conveying mechanism on the frame 1, the copper clad laminate conveying mechanism being connected to the frame 1 through a drive mechanism, the drive mechanism converting the power of the copper clad laminate conveying mechanism into driving the support frames 2 to descend a specified distance, a first synchronous wheel 72 being provided on the conveying roller of the conveyor belt mechanism 71, the first synchronous wheel 72 being driven to rotate by a motor 14 on the frame 1, a second synchronous wheel 74 being rotatably provided on the frame 1, the first synchronous wheel 72 and the second synchronous wheel 74 being connected by a synchronous belt 73, the copper clad laminate conveying mechanism including two sets of rotatable transmission rollers 12, both sets of transmission rollers 12 being rotatably provided on the frame 1, the two sets of transmission rollers 12 being connected by a copper clad laminate conveyor belt 13.

[0021] In use, this device supports the copper-clad laminates (CCLs) via the support frame 2. The transmission roller 12 rotates, driving the CCL conveyor belt 13. When the conveyor belt 13 rotates forward, it transports the CCLs onto the support frame 2. When the conveyor belt 13 rotates in reverse, it transfers the CCLs removed from the support frame 2 to the input end of processing or testing equipment, thus achieving both storage and output functions. Furthermore, the motor 14 drives the first synchronous pulley 72 to rotate, causing the conveyor belt mechanism 71 to move and remove the support frame 2 from the conveyor belt mechanism 71, providing space for the upper support frame 2 to descend, facilitating continuous stacking or unloading. During rotation, the first synchronous pulley 72 drives the second synchronous pulley 74 to rotate.

[0022] like Figure 7As shown, in this embodiment, the support frame 2 includes multiple sets of spaced receiving frames 20. The receiving frames 20 are provided with rollers and limiting blocks 22. The rollers can reduce the friction force on the copper-clad laminate when it moves, and can allow the copper-clad laminate moving from the copper-clad laminate conveyor belt 13 to move to the inside of the receiving frame 20 according to its own inertia. The movement of the copper-clad laminate can be limited by the limiting blocks 22 to prevent the copper-clad laminate from moving out of the receiving frame 20. Multiple sets of columns 21 are fixedly connected to the sides of the multiple sets of receiving frames 20.

[0023] like Figure 3 , 4 As shown in Figures 7 and 8, in this embodiment, the drive mechanism includes a pusher frame 5 slidably mounted on the frame 1. One end of the pusher frame 5 is provided with a push block 54 and a stop block 52 connected by a guide rod 51. A third elastic element 53 is provided between the stop block 52 and the frame 1. A pusher column 15 is provided on the side of the copper-clad laminate conveyor belt 13. The pusher column 15 can abut against the pusher frame 5. Multiple sets of flat tracks 23 are arranged on one side of the column 21. The end point of the flat track 23 is connected to the middle section of an adjacent set of flat tracks 23 through an inclined track 24. A first step 25 and a second step 26 are respectively provided at both ends of the inclined track 24. An installation frame 55 is provided on the pusher frame 5. A guide column 56 is slidably mounted on the installation frame 55. A fourth elastic element 57 is provided between the guide column 56 and the installation frame 55. The guide column 56 is locked at one end of the flat track 23.

[0024] When the copper-clad laminate conveyor belt 13 is in motion, it can transfer the copper-clad laminates into the support frame 2. After transfer, the push column 15 abuts against the push block 54, pushing the push block 54 to move and compressing the third elastic element 53 through the stop block 52. At the same time, it drives the guide column 56 to move, and under the action of the fourth elastic element 57, the guide column 56 is always in contact with the inner side of the flat track 23 or the inclined track 24. During the sliding process, under the action of the first step 25 and the second step 26, the guide column 56 can only slide into the upper inclined track 24 and the flat track 23 in sequence, thereby controlling the support frame 2 to descend at equal intervals. This allows the support frame 2 to automatically move down after receiving a set of copper-clad laminates to leave new holding space. The descent of the support frame 2 can be achieved regardless of how the copper-clad laminate conveyor belt 13 operates.

[0025] like Figure 1 , 3As shown in Figures 7 and 8, in this embodiment, two adjacent sets of support frames 2 are connected by a locking assembly. The locking assembly locks the positions of the two adjacent sets of support frames 2 and releases the lock when the lower set of support frames 2 contacts the conveyor belt mechanism 71. The locking assembly includes a first wedge block 3 slidably disposed on the column 21, the first wedge block 3 extending out of the column 21. A second wedge block 31 is disposed opposite to the first wedge block 3, the length of the second wedge block 31 being less than that of the first wedge block 3. The second wedge block 31 is slidably engaged on the adjacent set of columns 21. A first elastic element 32 is disposed between the first wedge block 3 and the inner wall of the column 21. A drive frame 17 is disposed on the frame 1, the column 21 is slidably engaged in the drive frame 17, and the support frame 2 can abut against the end face of the first wedge block 3 when it descends to contact the conveyor belt mechanism 71.

[0026] The movement of the support frame 2 is positioned by the drive frame 17 to prevent the support frame 2 from shifting. A new support frame 2 can be placed on the support frame 2 that is currently working on the device. The second wedge block 31 is pushed by the inclined surface to slide and retract until the support frame 2 is fully inserted. Under the action of the first elastic element 32, the second wedge block 31 is locked onto the column 21 of the upper set of support frames 2, thereby achieving rapid assembly. The support frame 2 automatically moves down during the loading or unloading process until the lower set of support frames 2 becomes ineffective and approaches the conveyor belt mechanism 71. The first wedge block 3 can then retract by abutting the drive frame 17 with its inclined surface, while simultaneously driving the second wedge block 31 to disengage from the upper set of support frames 2. The rear shell then descends under the action of the conveyor belt mechanism 71, moving the set of support frames 2 out of the device, providing descent space for the upper support frame 2 and achieving automatic unloading of the support frame 2. No manual disassembly is required, avoiding the equipment jamming and damage caused by untimely unloading that prevents the upper support frame 2 from descending.

[0027] like Figure 3 , 7 As shown in Figure 9, in this embodiment, the support frame 2 further includes a limiting component disposed on the receiving frame 20. The limiting component allows the receiving frame 20 to retract only when it moves to be flush with the copper-clad laminate conveyor belt 13. The limiting component includes a limiting plate 44 that is liftable and disposed on the end face of the receiving frame 20. A second drive column 45 is disposed at the end of the limiting plate 44. A drive block 41 is slidably disposed on the receiving frame 20. One end of the drive block 41 is inclined and extends out of the receiving frame 20. A second inclined groove 42 is provided on the drive block 41. The second drive column 45 is slidably engaged in the second inclined groove 42. A second elastic element 43 is disposed between the drive block 41 and the inner wall of the receiving frame 20. A baffle 4 is disposed on the frame 1. The baffle 4 can abut against the end face of the drive block 41.

[0028] When no external force is applied, the second elastic element 43 pushes the drive block 41 so that its end extends out of the receiving frame 20, while controlling the limiting plate 44 to be in a state protruding from the surface of the receiving frame 20, thereby limiting the copper-clad laminate on the receiving frame 20 and preventing the copper-clad laminate from slipping out. When the support frame 2 rises and falls, causing one set of receiving frames 20 to descend to be flush with the copper-clad laminate conveyor belt 13, the cooperation between the baffle 4 and the inclined surface at the end of the drive block 41 drives the drive block 41 to retract and compress the second elastic element 43. The cooperation between the second inclined groove 42 and the second drive column 45 controls the limiting plate 44 to retract, thereby releasing the limitation on the copper-clad laminate and facilitating the movement of the copper-clad laminate in or out.

[0029] like Figure 3 , 5 As shown in Figures 6 and 7, in this embodiment, the conveyor belt mechanism 71 is provided with a switching mechanism connected to the copper clad laminate conveying mechanism. The switching mechanism selectively converts the movement of the conveyor belt mechanism 71 into driving the copper clad laminate conveying mechanism to transmit in both forward and reverse directions. The switching mechanism is connected to the second synchronous wheel 74 and one of the sets of transmission rollers 12. The switching mechanism includes a mounting shaft 6 mounted on the transmission roller 12, on which a first bevel gear 61 and a first gear disc 62 are arranged opposite each other. A second bevel gear 63 is rotatably mounted on the frame 1 and is sleeved on the mounting shaft 6. A second gear disc 64 is arranged opposite to the first gear disc 62 on one side of the second bevel gear 63. A third bevel gear 65 is rotatably mounted on the frame 1 and meshes with the first bevel gear 61 and the second bevel gear 63. A double-sided gear disc 66 is slidably mounted on the mounting shaft 6 and a connecting frame 67 is mounted on the double-sided gear disc 66. The connecting frame 67 is slidably mounted on the second synchronous pulley 74. A control component for controlling the sliding of the double-sided gear disc 66 is also provided on the frame 1.

[0030] The control assembly includes a drive ring 81 that can slide laterally on the frame 1, a double-sided gear disk 66 that can be rotatably disposed within the drive ring 81, a drive seat 8 on the drive ring 81, a first inclined groove 82 on the drive seat 8, flat grooves 83 at both ends of the first inclined groove 82, a sliding groove 86 on the frame 1, a slider 84 that slides within the sliding groove 86, a first drive post 85 on the slider 84, and the first drive post 85 being engaged within one of the flat grooves 83.

[0031] In the initial state, the double-sided geared disc 66 meshes with the first geared disc 62. The position of the first drive column 85 is limited by the flat groove 83 to ensure the stability of the meshing. During the rotation of the second synchronous pulley 74 controlled by the motor 14, the rotation of the second synchronous pulley 74 can be transmitted to the double-sided geared disc 66 through the arrangement of the connecting frame 67. The double-sided geared disc 66 and the first geared disc 62 control the transmission roller 12 to rotate in the forward direction, driving the copper-clad laminate conveyor belt 13 to move in the forward direction, thereby conveying the copper-clad laminate output from the processing or testing equipment to the support frame 2. The first drive column 85 can be driven to slide along the slide groove 86 by moving the slider 84. Then, the first drive column 85 and the first inclined groove 82 can be used to drive the drive seat 8 to slide as a whole until the first drive column 85 is locked into the flat groove 83 again. When the drive seat 8 slides, it drives the double-sided toothed disc 66 to slide, so that it disengages from the first toothed disc 62 and engages with the second toothed disc 64. During the rotation of the second synchronous wheel 74, the transmission roller 12 can be controlled to rotate in the opposite direction by the cooperation of the first bevel gear 61, the second bevel gear 63 and the third bevel gear 65, so as to facilitate the delivery of the copper-clad laminate pushed out of the support frame 2 to the processing or testing equipment. This realizes the function switching of the device, and the switching process is convenient and quick, which can be completed without complicated operations, effectively improving work efficiency.

[0032] like Figure 2 , 3 As shown in Figures 7 and 8, in this embodiment, a material unloading mechanism is provided on the frame 1. This mechanism transfers the copper-clad laminate (CCL) from the support frame 2 to the CCL conveyor during reverse transport. The unloading mechanism includes a telescopic cylinder 9 mounted on the frame 1. The output end of the telescopic cylinder 9 is equipped with a push rod 91 flush with the CCL conveyor belt 13. A channel for the push rod 91 to be pushed into the receiving frame 20 is provided. A linkage assembly connected to the push column 15 is provided on the frame 1. This linkage assembly converts the movement of the push column 15 into control of the telescopic cylinder 9 during reverse transport. The linkage assembly includes a support frame 92 mounted on the frame 1. A control plate 93 is hinged to the end of the support frame 92. A control switch 95 electrically connected to the telescopic cylinder 9 is provided on the control plate 93. One end of a tension spring 94 is connected to the end of the support frame 92, and the other end is connected to the end of the control plate 93.

[0033] During the forward movement of the copper-clad laminate conveyor belt 13, when the push column 15 moves to the end of the frame 1 away from the support frame 2, it passes through the control plate 93 from bottom to top, which can drive the control plate 93 to rotate and stretch the tension spring 94 without triggering the control switch 95. The telescopic cylinder 9 does not move and can be reset by the action of the tension spring 94. When the copper-clad laminate conveyor belt 13 moves in the reverse direction, when the push column 15 moves to the end of the frame 1 away from the support frame 2, it passes through the control plate 93 from top to bottom, which can trigger the control switch 95, causing the telescopic cylinder 9 to complete one extension and retraction. This drives the push rod 91 to move and push the copper-clad laminate on the receiving frame 20 to the copper-clad laminate conveyor belt 13. The advancement of the copper-clad laminate is synchronized with the equal-interval descent of the support frame 2, ensuring that the copper-clad laminates on the support frame 2 can move sequentially into the processing or testing equipment without the need for manual unloading, further improving the efficiency of the workers and reducing their workload.

[0034] Specific usage and beneficial effects of the present invention: In traditional copper-clad laminate (CCL) stacking operations, workers must continuously shuttle between the conveyor and the stacking device, bending over to pick up CCLs and precisely place them on the support structure. A single operation exceeding half an hour can easily lead to back pain, arm fatigue, and other problems. Furthermore, each worker can only complete the transfer and stacking of approximately 8-10 CCLs per minute. This new device, through its fully automated design, completely replaces the manual handling process. The CCL conveyor mechanism can directly connect to the front-end production conveyor line, automatically receiving and transporting the CCLs to designated positions on the support frame 2. The drive mechanism drives the support frame 2 to precisely descend at a specified interval, ensuring that each CCL is stacked stably and at intervals, effectively protecting the surface of the CCLs. No manual adjustment of spacing or positioning is required. A full support frame 2 can be automatically transferred out of the device via the conveyor belt mechanism 71, facilitating continuous work and providing space for the upper support frame 2 to descend. By switching the mechanism, the movement of the conveyor belt mechanism 71 can be selectively converted to drive the copper-clad laminate conveying mechanism to convey in both forward and reverse directions. When the copper-clad laminate conveying mechanism is running in reverse, the unloading mechanism automatically completes the unloading of the copper-clad laminate, which facilitates the transfer of the copper-clad laminate on the support frame 2 to subsequent processing or inspection equipment. The staff only needs to monitor the start and stop of the device and install the support frame 2. One person can manage multiple devices at the same time. The stacking efficiency of a single device per hour is effectively improved, reducing the labor intensity of the staff and avoiding the risk of occupational injury caused by long-term repetitive labor.

[0035] The foregoing has shown and described the basic principles, main features, and advantages of the present invention. It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above. Modifications or improvements can be made to the present invention, which will be obvious to those skilled in the art. Therefore, all such modifications or improvements made without departing from the spirit of the present invention fall within the scope of protection claimed by the present invention.
