Description

TECHNICAL FIELD

[0001] The application relates to a tin paste spraying device, in particular to a tin paste spraying device for flexible copper clad plate production, and belongs to the technical field of flexible copper clad plate production. BACKGROUND

[0002] Flexible copper clad plate (FCC) has become the core substrate in the fields of smart phones, wearable devices, new energy vehicle electronics and flexible display screens due to its lightness, thinness, bendability, high and low temperature resistance and good electrical performance. In the automatic production process of FCC, tin paste spraying is a key pre-process for realizing the interconnection between the substrate and the copper foil circuit, and tin paste needs to be accurately sprayed at the preset circuit nodes to lay a foundation for forming stable solder joints in subsequent welding. The spraying precision, uniformity and operation adaptability directly determine the electrical performance and production yield of the FCC product. However, there are some problems in the application of the existing tin paste spraying device: firstly, the conveying mechanism of most devices has a fixed spacing, and can only adapt to a single width specification of the FCC plate. When switching to different size products, the conveying guide rail or positioning component needs to be disassembled and replaced, which not only consumes time but also easily damages the subsequent positioning reference due to disassembly deviation; secondly, the FCC is prone to edge warping or lateral deviation during conveying due to its flexible nature, and lacks coordinated constraints on the side and bottom, resulting in unstable plate position during spraying and problems such as tin paste deviation from the preset nodes; in addition, the conveying, positioning and spraying actions between devices lack coordination, which easily causes problems such as positioning delay after the plate is conveyed into position and reset jamming after spraying is completed, affecting the overall production efficiency.

[0007] The aforementioned solder paste spraying device for flexible copper clad laminate production has a locking block on the side of the first guide rail. The locking block has a vertical groove, and the lower end of the vertical groove has a circular groove that cooperates with the connecting rod. The upper end of the locking block is threaded with a locking screw that passes through the vertical groove. The outer end of the locking screw has a handle.

[0008] The aforementioned solder paste spraying device for flexible copper clad laminate production includes a side-top mechanism comprising multiple second mounting plates disposed inside the mounting rail. The second mounting plates are equipped with second cylinders, and the extension and retraction ends of the second cylinders are arranged upwards and connected to a side-top block.

[0012] Compared with the prior art, the present invention has the following beneficial effects: 1. In this invention, the variable-pitch conveying mechanism, which adjusts according to the width of the FCC material plate, can flexibly adapt to material plates of different widths. Product changeover can be achieved without disassembling or replacing parts, improving the device's adaptability to diverse production needs. When the material plate is conveyed inward by the variable-pitch conveying mechanism, the blocking mechanism can block it in its movement path until they collide, providing initial positioning for the material plate at the welding station and ensuring consistent placement. Subsequently, the lifting mechanism raises the material plate and separates it from the conveying end of the variable-pitch conveying mechanism, preventing interference from the conveying end to the material plate spraying operation. The side-top mechanism rises to support both sides of the material board, effectively preventing the flexible material board from tilting or shifting due to its own characteristics, further ensuring the positional stability of the material board during spraying. Then, the position of the spray nozzle and the camera equipment is adjusted by the horizontal and vertical moving mechanisms and the vertical moving mechanism. The camera equipment first confirms the welding position and can accurately locate the area to be sprayed, avoiding spraying deviation caused by slight displacement of the material board. Then, the solder paste in the solder paste cylinder is sprayed out from the spray nozzle by the solder paste valve, ensuring that the solder paste is accurately sprayed to the preset welding position, improving the accuracy and reliability of solder paste spraying on FCC material boards.

[0013] 2. When adjusting the installation rail spacing of the variable-pitch conveying mechanism, this invention only requires turning the handwheel to drive the connecting rod to rotate. The connecting rod drives the synchronous belt to rotate, thereby moving the first slider along the first guide rail, realizing convenient adjustment of the installation rail spacing without disassembling parts. It can quickly adapt to FCC boards of different widths, reducing the difficulty and time consumption of changeover operations. After adjustment, rotating the locking screw can bring the two ends of the vertical groove of the locking block closer to each other, allowing the circular groove to tightly abut against the connecting rod, effectively preventing it from rotating on its own due to vibration during device operation, thus ensuring the stability of the installation rail spacing and guaranteeing the positional accuracy of the board during conveying. This lays a reliable foundation for subsequent board positioning and solder paste spraying accuracy. Attached Figure Description

Detailed Implementation

[0016] The present invention will be further described below with reference to the accompanying drawings and embodiments, but this should not be construed as limiting the present invention.

[0017] Example: A solder paste spraying device for flexible copper clad laminate production, configured as follows Figures 1-8As shown, the machine includes a workbench 1 made of Q235 steel plate, which supports all components and provides a stable and flat mounting base for the mounting beams 2 and various functional mechanisms, preventing displacement due to vibration during operation. The workbench 1 is symmetrically equipped with mounting beams 2 made of 6061 aluminum alloy profiles, which are used to mount the horizontal and vertical moving mechanisms 3, providing high-altitude support for the spraying components and ensuring coverage of the entire work area. The horizontal and vertical moving mechanisms 3 are driven by two servo motors. The ball screw module is vertically stacked, and through the coordinated action of the two mechanisms, it achieves precise displacement control of the camera device 10 and the solder paste spraying valve 11 in the horizontal and vertical directions. This is used to adjust the planar position of the camera device 10 and the solder paste spraying valve 11, ensuring that they are accurately aligned with the preset soldering positions on the material board. A third mounting base 4, made of Q235 steel plate, is provided on the moving end of the horizontal and vertical moving mechanism 3. This third mounting base 4 is used to mount the vertical moving mechanism 9, providing a carrier for the vertical adjustment of the camera device 10 and the solder paste spraying valve 11. The device also includes: The variable-pitch conveyor mechanism 5, mounted on the workbench 1 and located between the mounting beams 2, is used to adjust the conveying pitch according to the width of the FCC material plate and to convey the material plate, adapting to the automated conveying of material plates of different specifications and improving the versatility of the device; such as Figures 3 to 5As shown, the variable-pitch conveying mechanism 5 includes symmetrically arranged first guide rails 100, with mounting rails 101 symmetrically arranged on the left and right sides above the first guide rails 100. The mounting rails 101 are made of Q235 steel pipe and are used to install the conveyor belt 102 and the baffle 106, providing a support frame for the material plate conveying. The conveyor belt 102, made of polyurethane material, is surrounded by the outer side of the mounting rails 101 and is used to carry and convey the material plate, driving the material plate to move towards the welding station through friction. A first mounting seat 103, made of Q235 steel plate, is provided below one side of the mounting rail 101 to fix one side of the mounting rail 101 and provide a fixed reference for adjusting the spacing of the mounting rails 101. The other side... A second mounting base 104 is provided below the mounting rail 101, and a first slider 105 is provided below the second mounting base 104 to drive the mounting rail 101 on one side to move, thereby realizing flexible adjustment of the spacing between the mounting rails 101. An inverted L-shaped baffle 106 is provided on the outer side of the mounting rail 101. The baffle 106 is made of 304 stainless steel plate, and a conveying cavity 107 is formed between the baffle 106 and the upper surface of the conveyor belt 102 to limit the deviation of the material plate during conveying, ensure that the material plate moves smoothly along the preset route, and avoid edge warping. An adjustment mechanism 108 is provided on the first guide rail 100 to adjust the spacing between the mounting rails 101, thereby driving the mounting rail 101 to move and precisely adjust the conveying spacing. The adjusting mechanism 108 includes a synchronous belt 109 wrapped around the first guide rail 100. The synchronous belt 109 is made of neoprene rubber and is fixedly connected to the first slider 105 on the same side for transmitting power and driving the first slider 105 to move along the first guide rail 100. A connecting rod 110 is provided between the first guide rails 100. The connecting rod 110 is made of 45# steel and is connected to the main shaft of the synchronous belt 109 for linkage of the synchronous belts 109 on both sides, ensuring that the synchronous belts 109 on both sides operate synchronously and realizing the smooth movement of the mounting rail 101. Figure 6As shown, one end of the connecting rod 110 is provided with a handwheel 111. The handwheel 111 is made of engineering plastic and is used for the operator to apply force and drive the connecting rod 110 to rotate by manual rotation. A locking block 112 is provided on the side of the first guide rail 100 on one side. The locking block 112 is made of Q235 steel plate and has a vertical groove 113. The lower end of the vertical groove 113 has a circular groove 114. The circular groove 114 cooperates with the connecting rod 110 to accommodate and limit the connecting rod 110. The connecting rod 110 is clamped and fixed by the contraction of the vertical groove 113. The upper end of the locking block 112 is provided with a locking screw 115 by thread. The locking screw 115 is made of 45 steel and passes through the vertical groove 113 to drive the vertical groove 113 to contract. The two ends of the vertical groove 113 are brought closer together by tightening the thread. The outer end of the locking screw 115 is provided with a handle 116. The handle 116 is made of engineering plastic to facilitate the operator to rotate the locking screw 115 and improve the ease of operation. When adjusting the spacing of the mounting rails 101 of the variable-pitch conveyor mechanism 5, the operator turns the handwheel 111. The handwheel 111 drives the connecting rod 110 to rotate, and the connecting rod 110 is linked to the main shaft of the synchronous belt 109 to rotate. When the synchronous belt 109 rotates, it drives the first slider 105 fixed to it to move smoothly along the first guide rail 100, thereby moving one side of the mounting rail 101 closer to or away from the fixed side mounting rail 101, realizing convenient adjustment of the spacing of the mounting rails 101 without disassembling any parts, and can quickly adapt to FCC material plates of different widths. This significantly reduces the difficulty and time required for model changeover operations. After adjustment, rotating the handle 116 drives the locking screw 115 to tighten. The locking screw 115 laterally presses the two ends of the vertical groove 113, causing the vertical groove 113 to contract and drive the inner wall of the circular groove 114 to tightly abut the connecting rod 110. Through friction, the connecting rod 110 is effectively restricted from rotating on its own due to vibration during device operation, preventing accidental offset of the mounting rail 101 spacing and ensuring the positional accuracy of the material board during material board transportation. This lays a reliable foundation for subsequent material board positioning and solder paste spraying accuracy.

[0018] The lifting mechanism 6, mounted on the workbench 1 and located below the conveying end of the variable-pitch conveyor mechanism 5, is used to lift the material plate that has been conveyed to the designated position, detaching it from the conveyor belt 102, providing stable support for the material plate spraying and preventing interference from the conveyor belt 102; for example... Figure 3 and Figure 4As shown, the lifting mechanism 6 includes multiple first mounting plates 60 arranged on the workbench 1. The first mounting plates 60 are made of Q235 steel plate and are used to mount the first cylinders 61, providing a stable mounting reference for the cylinders. The first cylinders 61 are mounted on the first mounting plates 60. The first cylinders 61 are standard aluminum alloy cylinders and are used to provide lifting power to drive the lifting plate 62 to rise and fall vertically. The telescopic end of the first cylinder 61 is set upward and connected to the lifting plate 62. The lifting plate 62 is made of 304 stainless steel plate and is used to receive and lift the material plate, increasing the contact area with the material plate and avoiding damage to the material plate. When the material plate is positioned by the blocking mechanism 8, the telescopic end of the first cylinder 61 extends, driving the lifting plate 62 to rise vertically. After the lifting plate 62 contacts the bottom of the material plate, it continues to rise, lifting the material plate until it abuts against the upper end face of the baffle 106, so that the material plate is completely separated from the surface of the conveyor belt 102, completely eliminating the influence of the operation of the conveyor belt 102 on the material plate, and providing a stable and static support environment for welding operations.

[0019] The side-top mechanism 7 is symmetrically arranged inside the variable-pitch conveying mechanism 5 to support and position the material plate on both sides after it is lifted, preventing the material plate from tilting and ensuring flatness during spraying; for example Figure 3 and Figure 4 As shown, the side-top mechanism 7 includes multiple second mounting plates 70 disposed inside the mounting rail 101. The second mounting plates 70 are made of Q235 steel plate and are used to mount the second cylinders 71, providing a mounting carrier for the side-top assembly. The second mounting plates 70 are equipped with the second cylinders 71, which are small aluminum alloy cylinders used to provide side-top power, drive the side-top block 72 to rise vertically and apply lateral force. The telescopic end of the second cylinder 71 is set upward and connected to the side-top block 72. The side-top block 72 is made of engineering plastic material and is used to contact and constrain both sides of the material plate to avoid direct metal contact that could scratch the copper foil on the surface of the material plate. As the lifting mechanism 6 lifts the material board, the extension end of the second cylinder 71 extends synchronously, driving the side top block 72 to rise vertically until it contacts both sides of the material board. Then, it continues to apply force to push the material board towards the baffle 106 until the side of the material board is in close contact with the baffle 106, forming a rigid constraint on the flexible material board from both sides. This effectively prevents the material board from tilting or shifting due to its own flexibility, ensuring the flatness of the soldering area and avoiding solder paste spraying deviation.

[0020] The blocking mechanism 8, located on the worktable 1 and in front of the lifting mechanism 6, is used to initially position the material plate at the welding station, ensuring consistent positioning of the material plate during delivery; for example... Figure 3 and Figure 4As shown, the blocking mechanism 8 includes a third mounting plate 80 mounted on the workbench 1. The third mounting plate 80 is made of Q235 steel plate and is used to mount the third cylinder 81 to provide stable support for the blocking assembly. The third mounting plate 80 is located at the front end of the lifting mechanism 6 to ensure that the blocking position corresponds precisely to the lifting area. The third mounting plate 80 is equipped with a third cylinder 81, which is a standard aluminum alloy cylinder used to provide lifting power and drive the buffer block 83 to protrude from the surface of the conveyor belt 102. The telescopic end of the third cylinder 81 is set upward and connected to a fourth mounting plate 82. The fourth mounting plate 82 is made of Q235 steel plate and is used to support the buffer block 83 to ensure that the two buffer blocks 83 are lifted and lowered synchronously. Buffer blocks 83 are symmetrically arranged on the upper end of the fourth mounting plate 82. The buffer blocks 83 are made of polyurethane material and are used to block the material plate and absorb the impact force to prevent the material plate from deforming at the edges or scratching the copper foil due to inertial collision. When the FCC material plate moves towards the welding station with the conveyor belt 102, the telescopic end of the third cylinder 81 extends in advance, driving the fourth mounting plate 82 and the buffer block 83 to rise vertically, so that the buffer block 83 protrudes 15-20mm from the surface of the conveyor belt 102 and blocks the material plate's travel path; when the material plate moves to the buffer block 83 under the drive of the conveyor belt 102, its front end contacts the buffer block 83 and is blocked, realizing the initial positioning of the welding station; the buffer block 83 absorbs the inertial impact force of the material plate through its own elastic deformation, reduces the contact stress, and effectively protects the edges of the material plate and the surface copper foil from damage.

[0021] The vertical moving mechanism 9, mounted on the third mounting base 4, is used to adjust the vertical height of the camera device 10 and the solder paste spraying valve 11, ensuring that both maintain a suitable distance from the surface of the material board, thereby improving positioning and spraying accuracy; Figure 7 As shown, the moving end of the vertical moving mechanism 9 is equipped with a camera device 10 and a solder paste spraying valve 11. The camera device 10 is an industrial CCD camera, used to photograph and identify the soldering parts on the board, providing a precise positioning reference for the solder paste spraying valve 11. The solder paste spraying valve 11 is a pneumatic dispensing valve, used to control the solder paste spraying, precisely spraying the solder paste to the preset area. The lower end of the solder paste spraying valve 11 is equipped with a spray nozzle 12, which is made of stainless steel, used to spray out solder paste, ensuring that the solder paste adheres to the board in a preset shape. The lower end of the solder paste spraying valve 11... A connection port 13 is provided on the outer side of the device. The connection port 13 is a threaded interface used to connect to the solder paste cartridge 14, providing solder paste supply to the solder paste spraying valve 11. The solder paste cartridge 14, made of food-grade plastic, is mounted on the connection port 13 and used to store solder paste for continuous supply during spraying. A holding clip 15, made of stainless steel, is provided on the side of the solder paste spraying valve 11. The holding clip 15 holds the outside of the solder paste cartridge 14 to secure it, preventing it from loosening or falling off due to vibration during high-frequency spraying and ensuring stable supply. Figure 7 and Figure 8As shown, the vertical moving mechanism 9 includes a fourth cylinder 90 mounted on the third mounting base 4. The fourth cylinder 90 is a standard aluminum alloy cylinder used to provide vertical lifting power, driving the camera device 10 and the solder paste spraying valve 11 to lift synchronously. The telescopic end of the fourth cylinder 90 is set downward and connected to a fifth mounting plate 91. The fifth mounting plate 91 is made of Q235 steel plate and is used to mount the camera device 10, providing a stable mounting surface for the camera device 10. The camera device 10 is mounted on the fifth mounting plate 91 to ensure that the shooting angle is perpendicular to the surface of the material plate. A second guide rail 92 is provided below the fourth cylinder 90. The second guide rail 92 is a linear guide rail, and a second slider 93 is provided on the second guide rail 92. The second slider 93 is a guide rail matching component used to guide the fifth mounting plate 91 to ensure that the fifth mounting plate 91 is level in the vertical direction. Stable movement, avoiding tilting; the third mounting base 4 is provided with a third guide rail 94 located on the side of the fourth cylinder 90. The third guide rail 94 has the same specifications as the second guide rail 92. The third guide rail 94 is provided with a third slider 95, which is fixedly connected to the sixth mounting plate 96 to guide the sixth mounting plate 96 and ensure that the solder paste spraying valve 11 rises and falls smoothly; the outer side of the third slider 95 is provided with the sixth mounting plate 96, which is made of the same material as the fifth mounting plate 91. The solder paste spraying valve 11 is set on the sixth mounting plate 96 to ensure that the relative position of the solder paste spraying valve 11 and the camera equipment 10 is fixed; a connecting block 97 is provided between the sixth mounting plate 96 and the fifth mounting plate 91. The connecting block 97 is made of Q235 steel plate and is used to link the sixth mounting plate 96 and the fifth mounting plate 91 to ensure that the two rise and fall synchronously. When the vertical height of the camera device 10 and the solder paste spraying valve 11 needs to be adjusted, the extension end of the fourth cylinder 90 extends or retracts, driving the fifth mounting plate 91 to move vertically along the mating direction of the second guide rail 92 and the second slider 93. At the same time, the sixth mounting plate 96 is driven to move synchronously along the mating direction of the third guide rail 94 and the third slider 95 through the connecting block 97, so that the camera device 10 and the solder paste spraying valve 11 always maintain the same vertical height. This ensures that the camera device 10 can vertically and accurately capture the image information of the solder spraying area, and determine the precise coordinates of the soldering part through image recognition technology, providing a positioning basis for the solder paste spraying valve 11 and improving the soldering positioning accuracy. After positioning, the solder paste spraying valve 11 is opened by pneumatic control, drawing the solder paste in the solder paste cylinder 14 into the valve body through the connecting port 13. Then, by precisely controlling the valve core opening, the solder paste is sprayed out from the spray outlet 12 in a preset amount and shape, accurately adhering to the soldering part of the board.

[0022] Working principle: First, the conveyor spacing is adjusted. Based on the width of the FCC material plate to be processed, the connecting rod 110 is driven to rotate by rotating the handwheel 111 of the variable-pitch conveyor mechanism 5. The connecting rod 110 drives the synchronous belt 109 to rotate, causing the first slider 105, which is fixed to the synchronous belt 109, to move along the first guide rail 100. This adjusts the spacing of the mounting rails 101 on both sides to match the width of the material plate. The changeover can be completed without disassembling the parts, improving the adaptability to different specifications of material plates. After the adjustment is completed, the locking screw 115 is rotated to retract the vertical groove 113 of the locking block 112, and the circular groove 114 tightly abuts against the connecting rod 110 to prevent it from rotating on its own due to vibration, ensuring the spacing is stable.

[0023] Next, the variable pitch conveyor mechanism 5 is started, and the FCC material plate is placed into the conveying cavity 107 formed by the outer baffle 106 of the mounting rail 101 and the conveyor belt 102. The conveyor belt 102 rotates and drives the material plate to move towards the welding station. At the same time, the third cylinder 81 of the blocking mechanism 8 extends and drives the fourth mounting plate 82 and the buffer block 83 to rise to protrude from the surface of the conveyor belt 102. When the material plate moves to the buffer block 83, it is blocked by the buffer block 83, realizing the initial positioning of the welding station. The buffer block 83 absorbs the inertial impact force of the material plate, avoids the deformation of the material plate edge or the scratch of the copper foil, and ensures the consistency of the material plate's position in the delivery position.

[0024] After the material plate is initially positioned, the first cylinder 61 of the lifting mechanism 6 extends, driving the lifting plate 62 to rise vertically. The lifting plate 62 contacts the bottom of the material plate and lifts it up, so that the material plate is completely separated from the conveyor belt 102, avoiding interference from the operation of the conveyor belt 102 to subsequent spraying operations. At the same time, the second cylinder 71 of the side lifting mechanism 7 extends synchronously, driving the side lifting block 72 to rise and abut against both sides of the material plate, pushing the material plate to move towards the baffle 106 until it is tightly attached to the baffle 106, forming a support constraint on the flexible material plate from both sides, preventing the material plate from tilting or shifting due to its own flexibility, and further ensuring the stability of the material plate position during spraying.

[0025] Subsequently, the spraying positioning and operation are carried out. The horizontal and vertical moving mechanism 3 is activated, and the horizontal and vertical positions of the third mounting base 4 are adjusted so that the camera device 10 and the solder paste spraying valve 11 are moved above the area of ​​the material board to be sprayed. Then, the fourth cylinder 90 of the vertical moving mechanism 9 is activated, driving the fifth mounting plate 91 to move vertically along the second guide rail 92 and the sixth mounting plate 96 along the third guide rail 94 simultaneously, adjusting the height of the camera device 10 and the solder paste spraying valve 11 to ensure that the camera device 10 can clearly capture the material board. The camera device 10 captures and identifies the soldering parts on the material board, accurately positioning the area to be sprayed, avoiding spraying deviations caused by slight offsets of the material board. After positioning is completed, the solder paste spraying valve 11 is opened, sucking the solder paste in the solder paste cylinder 14 into the connection port 13, and then accurately spraying it onto the preset soldering parts through the spray nozzle 12, completing the solder paste spraying operation of the FCC material board.
