Description
TECHNICAL FIELD
[0001] The utility model relates to low temperature co-fired ceramic processing technical field, concretely relates to a flexible low temperature co-fired ceramic straight pull type laminating machine. BACKGROUND
[0002] In the low temperature co-fired ceramic (LTCC) industry, after the ceramic sheet is punched and printed, the ceramic sheet needs to be stacked in up-down alignment. Then the stacked ceramic sheet is sent to subsequent processes for lamination. For the stacking process, there are two requirements in technology: firstly, the alignment of the stacked ceramic sheets needs to be accurate, because the ceramic sheet has a plurality of precisely aligned components (for example, printed circuits and conductor vias), if the alignment is not accurate, misalignment between the components may occur, resulting in substandard or failed products; secondly, the alignment between the adjacent two layers of ceramic sheets needs to be firm, if the alignment is not firm, the picking and placing of the ceramic sheet in the subsequent processes may result in alignment failure.
[0003] In the prior art, after the alignment of the multi-layer ceramic sheet, a fixed welding method is used between the adjacent ceramic sheets to meet the above two requirements. Specifically, there are two solutions.
[0004] One solution is overall hot pressing, that is, a planar overall contact hot pressing method is used to fix the relative position of the adjacent ceramic sheets, and a heated plane is used to directly hot press the two layers of ceramic sheets together. In this way, because the adjacent two layers of ceramic sheets are in overall contact, the firmness between the adjacent two layers of ceramic sheets is relatively high. However, this solution needs to apply overall high pressure, which may easily deform the corresponding mechanical structure, so that a large displacement between the adjacent two layers of ceramic sheets may occur after hot pressing.
[0005] Another solution is local spot welding, a limited number of hot welding heads are used to press on the adjacent two layers of ceramic sheets, and the adjacent two layers of ceramic sheets are connected together only at a limited number of points. In this way, the ceramic sheet only deforms in a small range of spot welding, and there is no deformation or little deformation at the non-welding position. The pressure caused by spot welding is small, so the displacement between the adjacent two layers of ceramic sheets is small after spot welding. However, it is also because of spot welding that the contact area between the ceramic sheets is small, resulting in weak firmness between the adjacent two layers of ceramic sheets, which may adversely affect the subsequent processes.

[0018] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0019] (1) The present invention has a high degree of automation. The material is picked up from the silo by the material picking mechanism and placed on the four corner cutting mechanism.

[0031] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.
[0032] To illustrate the technical solution described in this utility model, specific embodiments are described below.
[0033] Example
[0034] Please see Figure 1 , Figure 2 This embodiment provides a flexible low-temperature co-fired ceramic direct-pull stacking machine, including a frame 1 and a hopper 2, a material picking mechanism 3, a four-corner cutting mechanism 4, a transfer mechanism 5, a stacking mechanism 6, a material unloading and handling mechanism 7, and a material unloading and conveying mechanism 8 disposed on the frame 1.
[0035] in:
[0036] Combination Figure 3 As shown, two hoppers 2 are arranged side by side. Each hopper 2 has several layers of ceramic tile placement slots 21 from top to bottom. Ceramic tiles to be processed can be placed in the ceramic tile placement slots 21. Each layer of ceramic tile placement slots 21 in the hopper 2 is provided with a first telescopic cylinder 22 on both sides. The cylinder shaft of the first telescopic cylinder 22 faces the material picking mechanism 3 and is connected to the ceramic tile placement slot 21. Under the action of the first telescopic cylinder 22, the ceramic tile placement slot 21 can be opened in the direction of the material picking mechanism 3 to facilitate material picking.
[0037] The material handling mechanism 3 is located on one side of the hopper 2 and the four-corner cutting mechanism 4, combined with Figure 4 As shown, the material handling mechanism 3 includes a first X-axis linear drive module 31, a first Z-axis linear drive module 32, a second Z-axis linear drive module 33, a first suction cup material handling component 34, and a second suction cup material handling component 35. The first Z-axis linear drive module 32 and the second Z-axis linear drive module 33 are movably arranged side by side on the first X-axis linear drive module 31. The first suction cup material handling component 34 is movably arranged on the first Z-axis linear drive module 32, and the second suction cup material handling component 35 is movably arranged on the second Z-axis linear drive module 33. Under the action of the first X-axis linear drive module 31, the first suction cup material handling component 34 and the second suction cup material handling component 35 can move back and forth between the hopper 2 and the four-corner cutting mechanism 4, and can move up and down under the action of the first Z-axis linear drive module 32 and the second Z-axis linear drive module 33, respectively. The ceramic sheet to be processed in the hopper 2 is taken out by the material handling mechanism 3 and placed on the four-corner cutting mechanism 4.
[0038] The four-corner cutting mechanism 4, the transfer mechanism 5, the stacking mechanism 6, and the feeding and conveying mechanism 8 are distributed sequentially along the processing direction of the ceramic sheet. The four-corner cutting mechanism 4 is used to cut the four corners of the cast ceramic layer of the ceramic sheet to be processed, combined with... Figure 5 As shown, the four-corner cutting mechanism 4 includes a second X-axis linear drive module 41, a four-corner cutting adsorption platform 42, and a cutting debris suction device 43. The cutting debris suction device 43 is located above the second X-axis linear drive module 41, and the four-corner cutting adsorption platform 42 is movably mounted on the second X-axis linear drive module 41 and located below the cutting debris suction device 43. Each of the four corners of the four-corner cutting adsorption platform 42 has a cutting notch 421, and each cutting notch 421 has a cutting device 44 below it. The cutting device 44 includes a cutting cylinder 441 and a cutting tool 442, with the cutting tool 442 movably mounted in the cutting notch 421. The cylinder shaft of the cutting cylinder 441 faces upward and is connected to the cutter 442. The cutter 442 can extend and retract vertically from the cutting opening 421 under the action of the cutting cylinder 441. The ceramic sheet to be processed is placed onto the four-corner cutting adsorption platform 42 by the material handling mechanism 3 and adsorbed. It is then driven by the second X-axis linear drive module 41 to move below the cutting debris suction device 43 and pressed down under the action of the cutting debris suction device 43. Then, each of the four cutting cylinders 441 drives the cutter 442 to rise, thus achieving the cutting of the four corners of the cast ceramic layer at the bottom of the ceramic sheet. To achieve this, the cast ceramic layer of the ceramic sheet to be processed must be placed face down in the hopper 2. Figure 6 As shown, the cutting debris suction device 43 includes a support 431, a lifting cylinder 432, an adsorption plate 433, and several adsorption pipes 434. The lifting cylinder 432 is located on the top of the support 431, and the adsorption plate 433 is movably located at the bottom of the support 431. The cylinder shaft of the lifting cylinder 432 faces downward and is connected to the adsorption plate 433. The adsorption plate 433 can move up and down under the action of the lifting cylinder 432. The bottom of the adsorption plate 433 is provided with debris suction pipes at the four corners of the four corner cutting adsorption platform 42. The device has an adsorption port 435, and an adsorption pipe 434 is connected to the outside of each adsorption port 435. The ceramic sheet to be processed needs to be moved under the adsorption plate 433 of the device before the four corners are cut, so that after the four corners of the ceramic sheet to be processed are cut, the cut fragments can be sucked away from the adsorption port 435 through the adsorption pipe 434. Furthermore, an ion air bar 436 is also provided on the support 431. The ion air bar 436 can remove the static electricity of the ceramic sheet on the four corner cutting adsorption platform 42 by blowing out ion air.
[0039] After the ceramic sheet is cut, it is transferred to the stacking mechanism 6 through the transfer mechanism 5 for stacking. The ceramic sheet gripping part of the transfer mechanism 5 is equipped with a first heating plate 51, so that the ceramic sheet can be heated and softened by the first heating plate 51 during the transfer process.
[0040] The lamination mechanism 6 compresses several ceramic sheets to be processed using hydraulic pressure according to the lamination requirements, combined with... Figure 7 , Figure 8 As shown, the lamination mechanism 6 includes a third X-axis linear drive module 61, a lower mold 62, a hydraulic press 63, a PE film collection box 64, two front clamping and tearing film devices 65, a Y-axis linear drive module 66, and two rear clamping and tearing film devices 67. An upper mold 631 is movably mounted in the hydraulic press 63, and a lower mold 62 is movably mounted on the third X-axis linear drive module 61 and located below the upper mold 631. The lower mold 62 receives the ceramic sheets to be processed from the transfer mechanism 5 and transports them directly below the upper mold 631 for hydraulic pressing. Both the upper mold 631 and the lower mold 62 are equipped with second heating plates 68, forming a hot pressing station between them. Since the ceramic sheets have been preheated and softened in the previous step, a relatively high temperature (65°C) is not required in this process to ensure a firm connection between adjacent ceramic sheets and prevent deformation. The PE film collection box 64 is located on one side of the third X-axis linear drive module 61, and the Y-axis... A linear drive module 66 is positioned above the PE film collection box 64. Two front clamping tearing devices 65 are positioned opposite each other on the front side of the hot pressing station. Two rear clamping tearing devices 67 are movably mounted on the Y-axis linear drive module 66 and positioned opposite each other on the rear side of the hot pressing station. The two front clamping tearing devices 65 and the two rear clamping tearing devices 67 correspond to each other front and back. During the hot pressing process, the two front clamping tearing devices 65 and the two rear clamping tearing devices 67 clamp the PE film on the ceramic sheet. Due to the material properties of the PE film, it will not be cut by the cutting tool of the four-corner cutting mechanism. Therefore, after the four corners of the PE film on the ceramic sheet are cut off, four corners will be exposed. The front clamping tearing devices 65 and the rear clamping tearing devices 67 then tear off the entire PE film by clamping the exposed corner pieces. Then, under the action of the Y-axis linear drive module 66, the two rear clamping tearing devices 67 move backward to throw the PE film into the PE film collection box 64 below.
[0041] After the stacking is completed, the finished product is transported to the unloading conveyor mechanism 8 by the unloading and handling mechanism 7 for unloading. The finished product that has been processed on the lower mold 62 is transported to the bottom of the unloading and handling mechanism 7 by the third X-axis linear drive module 61. The unloading and handling mechanism 7 then grabs and places it on the unloading conveyor mechanism 8. The unloading conveyor mechanism 8 is equipped with a cooling box 81, so that the finished product is cooled from 65°C to 40°C during the unloading and conveying process. This repairs the micro-deformation of the ceramic sheet during the hot pressing process, thereby ensuring the quality of the finished product.
[0042] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
