Description

Technical Field

[0001] The present invention belongs to the technical field of automation equipment, and in particular relates to an MLCC stacking device. Background Art

[0002] ‌MLCC stacking refers to a structure of chip-type multilayer ceramic capacitors (Multi-layer Ceramic Capacitors), which consists of multiple ceramic dielectric diaphragms with electrodes printed on them stacked in a staggered manner, sintered at high temperature to form a ceramic chip, and then sealed with a metal layer (external electrode) at both ends of the chip to form a monolithic structure. This structure makes MLCC have the advantages of small size, large capacity, high mechanical strength, good moisture resistance, small internal inductance, good high-frequency characteristics, and high reliability. ‌

[0003] In the MLCC lamination process, when the adsorption plate adsorbs the electrode or ceramic film for lamination, it is often laminated by pressing from top to bottom or pushing from bottom to top. Due to the characteristics of the material, in order to ensure that the film can be adhered together by pressure during lamination, the adsorption plate and the lower mold need to be heated. At the same time, during the lamination process, since the air between the upper and lower molds has no time to escape, a small amount of gas will remain in the diaphragm, forming bubbles. As the bubbles accumulate, there will be a high accumulation in the lamination, which will cause uneven pressure distribution, the electrode will be crushed or deformed, and affect the quality of the finished product. Summary of the invention

[0004] The object of the present invention is to provide an MLCC stacking device to solve the technical defects described in the background technology.

[0005] The MLCC stacking device includes a stacking station, which is equipped with a lower gold mold component, an upper gold mold component and a pressing power module. The lower gold mold component is provided with a bearing seat for limiting and placing the first raw material plate, and the bearing seat is provided with a lower heating unit and a lower vacuum hole for adsorbing the first raw material plate. The upper gold mold component is provided with an adsorption seat for adsorbing the second raw material plate. The outer peripheral wall of the upper gold mold component is hard-connected with a movable groove seat, and the movable groove seat is provided with a slide groove and a spring. A peripheral seat connected to the spring transmission is slid in the slide groove, and a sealing ring for contacting the peripheral seat is fixed in the slide groove. The peripheral seat is provided with an exhaust vent so that under the drive of the pressing power module Before the mold assembly and the upper mold assembly are brought together to abut the first raw material plate and the second raw material plate, the spring pushes the outer seat sleeve to surround the outer periphery of the first raw material plate and the second raw material plate and abut against the upper surface of the lower mold assembly, so that the first raw material plate and the second raw material plate are in a closed space, thereby increasing the air pressure in the closed space through the exhaust pores to reduce the friction force when the first raw material plate and the second raw material plate are aligned and abutted, and before the pressing power module drives the lower mold assembly and the upper mold assembly to abut to overlap the first raw material plate and the second raw material plate, the exhaust pores are used to evacuate the closed space to avoid gas remaining in the overlapped first raw material plate and the second raw material plate;

[0006] It also includes a discharging station, which is equipped with a material taking rack, which is equipped with support slides and shifting power modules located on both sides of the lower mold component and the upper mold component, and a shifting rack sliding on the support slide, and a material taking conveying line is installed on the shifting rack, so that when the lower mold component and the upper mold component are opened to each other, the lower vacuum hole stops adsorption, and the adsorption seat adsorbs the finished product formed by the superposition of the first raw material plate and the second raw material plate to rise, and the shifting power module drives the material taking conveying line to move below the finished product, so that the adsorption seat can place the adsorbed finished product on the material taking conveying line for taking out;

[0007] The unloading station is also equipped with a delivery conveyor line. After the finished product is placed on the retrieving conveyor line, the shifting power module is also used to drive the retrieving conveyor line close to the delivery conveyor line, so that the retrieving conveyor line can deliver the finished product to the delivery conveyor line, and the delivery conveyor line can deliver the finished product away;

[0008] The MLCC stacking device further includes a carrier. When the shift power module drives the material conveying line to move below the finished product, the carrier is also moved below the finished product so that the finished product can be placed in the carrier.

[0009] The unloading station is also equipped with a lifting power module and a carrier supply line. The lifting power module is transmission-connected to a lifting frame, and the lifting frame is provided with at least two layers of docking channels. There is a height difference between the carrier supply line and the material taking conveyor line. One layer of the docking channels is located between the material taking conveyor line and the delivery conveyor line, and the outlet of the carrier supply line is located on the docking channel side of the other layer, so that the material taking conveyor line transfers the carrier with the finished product through the docking channel to the delivery conveyor line for delivery. During this period, the carrier supply line can supply another empty carrier to the docking channel of the other layer. The lifting power module is used to drive the lifting frame to drive the docking channels located next to the outlet of the carrier supply line to move between the material taking conveyor line and the delivery conveyor line.

[0010] Based on the above technical solution, the present invention can achieve the following beneficial effects:

[0011] 1. Before or after the pressing power module drives the lower metal mold component and the upper metal mold component to approach and the first raw material plate and the second raw material plate are attached to each other, the outer seat cover is pre-enclosed around the outer periphery of the first raw material plate and the second raw material plate and attached to the upper surface of the lower metal mold component, so that the first raw material plate and the second raw material plate are in a closed space. At this time, the air pressure in the closed space is increased through the exhaust pores, so that when the adsorption seat drives the second raw material plate to move horizontally and vertically, the friction between the first raw material plate and the second raw material plate is reduced, thereby reducing damage to the first raw material plate and the second raw material plate;

[0012] 2. Before the pressing power module drives the lower metal mold assembly and the upper metal mold assembly to move closer and overlap the first raw material plate and the second raw material plate to form a finished product, the enclosed space is evacuated in advance through the exhaust holes to avoid gas residue in the overlapped first raw material plate and the second raw material plate, and to avoid bubbles accumulating in the stack and affecting the height, so as to achieve a more even and stable distribution of pressure on the first raw material plate and the second raw material plate, thereby improving the quality of the finished product.

[0013] 3. After the lower mold component and the upper mold component are brought close to each other and the first raw material plate and the second raw material plate are attached and overlapped to form a finished product, the lower mold component and the upper mold component are opened to each other. At this time, the lower vacuum hole stops adsorbing, and the adsorption seat adsorbs the finished product formed by the first raw material plate and the second raw material plate and rises. After that, the power module drives the material taking conveyor line to move below the finished product. After that, the adsorption seat places the adsorbed finished product on the material taking conveyor line, and the power module drives the material taking conveyor line to move away from below the adsorption seat, thereby taking out the finished product;

[0014] 4. Since the first raw material plate and the second raw material plate need to be heated when they are superimposed, taking out the finished product through a mechanical mechanism can improve the safety of the operation.

[0015] 5. After the finished product is placed on the material retrieving conveyor line and the shifting power module drives the material retrieving conveyor line to move away from under the adsorption seat, the material retrieving conveyor line is connected to the delivery conveyor line so that the material retrieving conveyor line can deliver the finished product to the delivery conveyor line, and the delivery conveyor line can transport the finished product to the next workstation, the next equipment or to a centralized storage point.

[0016] 6. When the finished products are transported on the material conveyor line and the delivery conveyor line, the finished products can be effectively protected, thereby reducing the wear of the finished products.

[0017] 7. While the retrieving conveyor line is transferring the carrier with the finished product through one of the docking channels to the delivery conveyor line, the carrier supply line supplies another empty carrier to the docking channel of another layer. After that, after the delivery conveyor line sends away the carrier with the finished product, the lifting power module drives the lifting frame to lift, and the lifting frame drives the docking channel with the empty carrier to be spliced ​​with the retrieving conveyor line. After that, the retrieving conveyor line takes out the empty carrier from the docking channel and moves it to the bottom of the next finished product to receive the next finished product. During this period, the lifting power module drives the lifting frame to lift and reset. Therefore, after the carrier completes receiving the finished product and sends the finished product away, it can supply a new empty carrier to the retrieving conveyor line to receive the next finished product.

[0018] 8. Since only a single conveyor line (i.e., a material taking conveyor line) is needed to complete the process of receiving empty carriers, transferring empty carriers to receiving finished products, and sending away carriers with finished products, the space occupied by the equipment and the preparation cost can be reduced;

[0019] 9. During the process of the retrieving conveyor line transferring the carrier with the finished product through one of the docking channels to the delivery conveyor line, the carrier supply line supplies another empty carrier to the docking channel of another layer. After the delivery conveyor line sends away the carrier with the finished product, the lifting power module drives the lifting frame to lift, and the lifting frame drives the docking channel with the empty carrier to be spliced ​​with the retrieving conveyor line. Therefore, it can effectively simplify the process of taking out the finished product and loading the carrier, thereby improving efficiency.

[0020] 10. After the delivery conveyor line sends away the carrier with the finished products, the lifting power module drives the lifting frame to rise and fall, and the lifting frame drives the docking channel with the empty carrier to be spliced ​​with the material-retrieving conveyor line. Therefore, the delivery conveyor line can be installed overlapping with the carrier supply line, thereby reducing the footprint of the equipment.

[0021] In order to further optimize the above technical solution, it can be optionally combined with one or more of the following implementation methods without conflict.

[0022] In some embodiments, the movable groove seat is equipped with a cylinder that is transmission-connected to the outer seat. Before the pressing power module drives the lower metal mold assembly and the upper metal mold assembly to move closer and affix the first raw material plate to the second raw material plate, the cylinder drives the outer seat to press down and fit against the upper surface of the lower metal mold assembly. When the pressing power module drives the lower metal mold assembly and the upper metal mold assembly to move closer and affix and overlap the first raw material plate to the second raw material plate, the cylinder drives the outer seat to rise to offset the stroke of the lower metal mold assembly and the upper metal mold assembly moving closer.

[0023] Based on the above technical solution, the present invention further achieves the following beneficial effects:

[0024] 1. Before the pressing power module drives the lower mold assembly and the upper mold assembly to move closer and the first raw material plate and the second raw material plate are attached to each other, the outer seat is driven by the cylinder to press down and fit to the upper surface of the lower mold assembly, so that the outer seat can provide a closed space for the first raw material plate and the second raw material plate more stably;

[0025] 2. When the pressing power module drives the lower mold component and the upper mold component to approach each other and the first raw material plate and the second raw material plate are attached and overlapped, the cylinder drives the peripheral seat to rise to offset the stroke of the lower mold component and the upper mold component approaching each other, so as to avoid the conflict between the driving force of the cylinder and the power of the lower mold component and the upper mold component approaching each other;

[0026] 3. So that the spring can be used to buffer the impact force when the outer seat and the upper mold component are in contact.

[0027] In some embodiments, the peripheral seat is provided with a sealing strip in contact with the upper surface of the lower gold mold component;

[0028] Based on the above technical solution, due to the provision of the sealing strip, it is possible to effectively prevent the enclosed space from leaking air through the gap between the lower metal mold component and the peripheral seat.

[0029] In some embodiments, the docking channel is a docking platform with a plurality of sliding beads on the top surface, the width of the docking platform is smaller than the width of the carrier, and the outer boundary of the docking platform can be close to the carrier supply line or the material collection conveyor line and the delivery conveyor line;

[0030] Based on the above technical solution, the present invention further achieves the following beneficial effects:

[0031] 1. After the carrier supply line transports the carrier to the docking platform and the carrier moves out of the carrier supply line due to inertia, a part of the carrier will protrude from the docking platform. At this time, the lifting power module drives the lifting frame to lift and lower. When the lifting frame drives the docking channel where the empty carrier is placed to connect with the material-taking conveyor line, the part of the carrier protruding from the docking platform will fall onto the material-taking conveyor line, so that the material-taking conveyor line can take out the empty carrier on the docking platform;

[0032] 2. The material taking conveyor line transports the carrier with the finished product to the docking platform and after the carrier moves out of the carrier supply line by inertia, part of the carrier will protrude from the docking platform. At this time, part of the carrier will move to the delivery conveyor line, so that the delivery conveyor line can take out the carrier with the finished product on the docking platform;

[0033] 3. Since the material-collecting conveyor line can take out the empty carriers on the docking platform, and the delivery conveyor line can take out the carriers with finished products on the docking platform, there is no need to set up a power module on the docking platform to drive the carrier to move, thereby further reducing the equipment to manufacture finished products and simplifying the logic of driving the transport vehicle.

[0034] In some embodiments, the carrier is provided with an information sensing strip, and a plurality of S-pole magnetic blocks and N-pole magnetic blocks are arranged in the information sensing strip. The number and arrangement order of the S-pole magnetic blocks and N-pole magnetic blocks in the information sensing strip of each carrier are different. The material conveyor line is provided with a magnetic sensor. When the material conveyor line drives the carrier to move, the carrier drives the information sensing strip to slide past the magnetic sensor. The magnetic sensor is used to sense the number and arrangement of the S-pole magnetic blocks and N-pole magnetic blocks in the information sensing strip of the carrier to mark the position and information of the carrier.

[0035] Based on the above technical solution, the present invention can further achieve the following beneficial effects: when the finished products are placed in the carrier, the magnetic sensor can sense the number and arrangement of the S-pole magnetic blocks and the N-pole magnetic blocks of the carrier information sensing strip to locate the carrier and register the information, thereby facilitating the classification, storage and processing of the finished products in each carrier.

[0036] In some embodiments, the information sensing strip has a plurality of the S-pole magnetic blocks or the N-pole magnetic blocks arranged in series. When the carrier drives the information sensing strip to slide past the magnetic sensor, the magnetic sensor is used to mark the position and information of the carrier by sensing the duration of the S-pole or N-pole magnetic field.

[0046] In order to make the objectives, technical solutions and advantages of the present invention more clear, this specific implementation method further describes the present invention in detail with reference to the accompanying drawings.

[0047] like Figures 1 to 6As shown, this specific embodiment provides an MLCC lamination device, which includes a lamination station 1, the lamination station 1 is equipped with a lower gold mold component 11, an upper gold mold component 12 and a pressing power module 13, the lower gold mold component 11 is provided with a bearing seat 111 for limiting and placing the first raw material plate, the bearing seat 111 is provided with a lower heating unit and a lower vacuum hole 112 for adsorbing the first raw material plate, the upper gold mold component 12 is provided with an adsorption seat 121 for adsorbing the second raw material plate, the outer peripheral wall of the upper gold mold component 12 is hard-connected with a movable groove seat 14, the movable groove seat 14 is provided with a slide groove and a spring 141 is installed, a peripheral seat 15 slidingly connected to the spring 141 in a transmission manner is provided in the slide groove, a sealing ring 142 for contacting the peripheral seat 15 is fixed in the slide groove, and the peripheral seat 15 is provided with The exhaust pores are used so that before the pressing power module 13 drives the lower mold component 11 and the upper mold component 12 to move closer and the first raw material plate and the second raw material plate are attached to each other, the spring 141 pushes the outer seat 15 to surround the outer periphery of the first raw material plate and the second raw material plate and to fit with the upper surface of the lower mold component 11, so that the first raw material plate and the second raw material plate are in the closed space 16, thereby increasing the air pressure in the closed space 16 through the exhaust pores to reduce the friction force when the first raw material plate and the second raw material plate are aligned and attached to each other, and before the pressing power module 13 drives the lower mold component 11 and the upper mold component 12 to move closer and the first raw material plate and the second raw material plate are superimposed, the exhaust pores are used to evacuate the closed space 16 to avoid gas remaining in the superimposed first raw material plate and the second raw material plate.

[0048] Before or after the pressing power module 13 drives the lower mold component 11 and the upper mold component 12 to approach and the first raw material plate and the second raw material plate are attached to each other, the outer seat 15 is pre-enclosed around the outer periphery of the first raw material plate and the second raw material plate and attached to the upper surface of the lower mold component 11, so that the first raw material plate and the second raw material plate are in the closed space 16. At this time, the air pressure in the closed space 16 is increased through the exhaust pores, so that when the adsorption seat 121 drives the second raw material plate to move horizontally and vertically, the friction between the first raw material plate and the second raw material plate is reduced, thereby reducing damage to the first raw material plate and the second raw material plate;

[0049] Before the pressing power module 13 drives the lower metal mold component 11 and the upper metal mold component 12 to move together and overlap the first raw material plate and the second raw material plate to form a finished product, the enclosed space 16 is evacuated in advance through the exhaust holes to avoid gas residue in the overlapped first raw material plate and the second raw material plate, and to avoid bubbles accumulating and remaining in the stack to affect the height, so as to achieve a more uniform and stable distribution of pressure on the first raw material plate and the second raw material plate, thereby improving the quality of the finished product.

[0050] In some embodiments, the movable groove seat 14 is installed with a cylinder 143 which is transmission-connected to the outer seat 15. Before the pressing power module 13 drives the lower mold component 11 and the upper mold component 12 to move closer and affix the first raw material plate to the second raw material plate, the cylinder 143 drives the outer seat 15 to be pressed down and affixed to the upper surface of the lower mold component 11. When the pressing power module 13 drives the lower mold component 11 and the upper mold component 12 to move closer and affix and overlap the first raw material plate to the second raw material plate, the cylinder 143 drives the outer seat 15 to rise and offset the stroke of the lower mold component 11 and the upper mold component 12 moving closer.

[0051] Before the pressing power module 13 drives the lower mold assembly 11 and the upper mold assembly 12 to approach and attach the first raw material plate to the second raw material plate, the cylinder 143 drives the peripheral seat 15 to press down and attach to the upper surface of the lower mold assembly 11, so that the peripheral seat 15 can provide a closed space 16 for the first raw material plate and the second raw material plate more stably. At this time, the spring 141 can be used to buffer the impact force when the peripheral seat 15 and the upper mold assembly 12 are attached.

[0052] When the pressing power module 13 drives the lower mold component 11 and the upper mold component 12 to move closer to each other and overlap the first raw material plate and the second raw material plate, the cylinder 143 drives the outer seat 15 to rise to offset the movement of the lower mold component 11 and the upper mold component 12 moving closer to each other, thereby avoiding the conflict between the driving force of the cylinder 143 and the power when the lower mold component 11 and the upper mold component 12 move closer to each other.

[0053] In some embodiments, the peripheral seat 15 is provided with a sealing strip 151 in contact with the upper surface of the lower mold component 11. Due to the provision of the sealing strip 151, the airtight space 16 can be effectively prevented from leaking from the gap between the lower mold component 11 and the peripheral seat 15.

[0054] In some embodiments, the MLCC lamination device further includes a discharging station 2, which is equipped with a material picking rack, which is equipped with a supporting slide rail 21 and a shifting power module 22 located on both side plates of the lower mold component 11 and the upper mold component 12, and a shifting frame 23 slides on the supporting slide rail 21, and a material picking conveyor line 231 is installed on the shifting frame 23, so that when the lower mold component 11 and the upper mold component 12 are opened to each other, the lower vacuum hole 112 stops adsorption, and the adsorption seat 121 adsorbs the finished product formed by the superposition of the first raw material plate and the second raw material plate to rise, and the shifting power module 22 drives the material picking conveyor line 231 to move to the bottom of the finished product, so that the adsorption seat 121 can place the adsorbed finished product on the material picking conveyor line 231 for removal.

[0055] After the lower mold component 11 and the upper mold component 12 are brought together to stick and overlap the first raw material plate and the second raw material plate to form a finished product, the lower mold component 11 and the upper mold component 12 are opened to each other. At this time, the lower vacuum hole 112 stops adsorption, and the adsorption seat 121 adsorbs the finished product formed by the overlap of the first raw material plate and the second raw material plate to rise. Thereafter, the power module drives the material collection conveyor line 231 to move to the bottom of the finished product. Thereafter, the adsorption seat 121 places the adsorbed finished product on the material collection conveyor line 231, and the power module drives the material collection conveyor line 231 to move away from under the adsorption seat 121, thereby taking out the finished product.

[0056] Since the first raw material plate and the second raw material plate need to be heated when they are superimposed, taking out the finished product by a mechanical mechanism can improve the safety of the operation.

[0057] In some embodiments, the unloading station 2 is also equipped with a delivery conveyor line 25. After the finished product is placed on the material collection conveyor line 231, the shifting power module 22 is also used to drive the material collection conveyor line 231 close to the delivery conveyor line 25, so that the material collection conveyor line 231 can deliver the finished product to the delivery conveyor line 25, so that the delivery conveyor line 25 can deliver the finished product away.

[0058] After the finished product is placed on the material picking conveyor line 231 and the shifting power module 22 drives the material picking conveyor line 231 to move away from under the adsorption seat 121, the material picking conveyor line 231 is connected to the delivery conveyor line 25 so that the material picking conveyor line 231 can deliver the finished product to the delivery conveyor line 25, and the delivery conveyor line 25 can transport the finished product to the next workstation, the next equipment or to a centralized storage point.

[0059] In some embodiments, the MLCC stacking device further includes a carrier 3 . When the shifting power module 22 drives the material conveying line 231 to move below the finished product, the carrier 3 is also moved below the finished product so that the finished product can be placed in the carrier 3 .

[0060] When the material taking conveyor line 231 and the delivery conveyor line 25 transport the finished products, the finished products can be effectively protected, thereby reducing the wear and tear of the finished products.

[0061] In some embodiments, the discharge station 2 is also equipped with a lifting power module 26 and a carrier supply line 27. The lifting power module 26 is transmission-connected to a lifting frame 261. The lifting frame 261 is provided with at least two layers of docking channels 262. There is a height difference between the carrier supply line 27 and the material taking conveyor line 231. One layer of docking channels 262 is located between the material taking conveyor line 231 and the delivery conveyor line 25, while the outlet of the carrier supply line 27 is located on the side of the docking channel 262 of another layer, so that the material taking conveyor line 231 transfers the carrier 3 with the finished product through the docking channel 262 to the delivery conveyor line 25 for delivery. During this period, the carrier supply line 27 can supply another empty carrier 3 to the docking channel 262 of another layer. The lifting power module 26 is used to drive the lifting frame 261 to drive the docking channels 262 located next to the outlet of the carrier supply line 27 to move between the material taking conveyor line 231 and the delivery conveyor line 25.

[0062] While the material-taking conveyor line 231 transfers the carrier 3 with the finished product through one of the docking channels 262 to the delivery conveyor line 25, the carrier supply line 27 supplies another empty carrier 3 to the docking channel 262 of another layer. Thereafter, after the delivery conveyor line 25 sends away the carrier 3 with the finished product, the lifting power module 26 drives the lifting frame 261 to rise and fall, and the lifting frame 261 drives the docking channel 262 with the empty carrier 3 to be spliced ​​with the material-taking conveyor line 231. Thereafter, the material-taking conveyor line 231 takes the empty carrier 3 out of the docking channel 262 and uses it to move to the bottom of the next finished product to pick up the next finished product. During this period, the lifting power module 26 drives the lifting frame 261 to rise and fall and reset. Therefore, after the carrier 3 completes picking up the finished product and sends the finished product away, a new empty carrier 3 can be supplied to the material-taking conveyor line 231 to pick up the next finished product.

[0063] Since only a single conveyor line (i.e., the material taking conveyor line 231) is needed to complete the process of receiving the empty carrier 3, transferring the empty carrier 3 to the receiving end product, and sending away the carrier 3 with the end product, the space occupied by the equipment and the preparation cost can be reduced;

[0064] In addition, during the process that the material taking conveyor line 231 transfers the carrier 3 with the finished product through one of the docking channels 262 to the delivery conveyor line 25, the carrier supply line 27 supplies another empty carrier 3 to the docking channel 262 of another layer. After the delivery conveyor line 25 sends away the carrier 3 with the finished product, the lifting power module 26 drives the lifting frame 261 to move up and down, and the lifting frame 261 drives the docking channel 262 with the empty carrier 3 to be spliced ​​with the material taking conveyor line 231. Therefore, it can effectively simplify the process of taking out the finished product and loading the carrier 3, thereby improving efficiency.

[0065] At the same time, after the delivery conveyor line 25 sends away the carrier 3 carrying the finished product, the lifting power module 26 drives the lifting frame 261 to rise and fall, and the lifting frame 261 drives the docking channel 262 where the empty carrier 3 is placed to be spliced ​​with the material conveyor line 231. Therefore, the delivery conveyor line 25 can be installed in a superimposed manner with the carrier supply line 27, thereby reducing the footprint of the equipment.

[0066] In some embodiments, the docking channel 262 is a docking platform with a plurality of sliding balls on the top surface. The width of the docking platform is smaller than the width of the carrier 3 , and the outer boundary of the docking platform can be close to the carrier supply line 27 or the material conveyor line 231 and the delivery conveyor line 25 .

[0067] After the carrier supply line 27 transports the carrier 3 to the docking platform and the carrier 3 moves out of the carrier supply line 27 due to its inertia, a part of the carrier 3 will protrude from the docking platform. At this time, the lifting power module 26 drives the lifting frame 261 to lift and lower. When the lifting frame 261 drives the docking channel 262 where the empty carrier 3 is placed to be connected with the material conveyor line 231, the part of the carrier 3 protruding from the docking platform will fall onto the material conveyor line 231, so that the material conveyor line 231 can take out the empty carrier 3 on the docking platform.

[0068] The material taking conveyor line 231 transports the carrier 3 with the finished products to the docking platform and after the carrier 3 moves out of the carrier supply line 27 by inertia, a part of the carrier 3 will protrude from the docking platform. At this time, a part of the carrier 3 will move to the delivery conveyor line 25, so that the delivery conveyor line 25 can take out the carrier 3 with the finished products on the docking platform.

[0069] Since the material collection conveyor line 231 can take out the empty carrier 3 on the docking platform, and the delivery conveyor line 25 can take out the carrier 3 with the finished product on the docking platform, there is no need to set up a power module on the docking platform to drive the carrier 3 to move, thereby further reducing the equipment to manufacture the finished product and simplifying the logic of driving the transport vehicle 3.

[0070] In some embodiments, the carrier 3 is provided with an information sensing strip 31, and a plurality of S-pole magnetic blocks 32 and N-pole magnetic blocks 33 are arranged in the information sensing strip 31. The number and arrangement order of the S-pole magnetic blocks 32 and N-pole magnetic blocks 33 in the information sensing strip 31 of each carrier 3 are different. The material conveyor line 231 is provided with a magnetic sensor 232. When the material conveyor line 231 drives the carrier 3 to move, the carrier 3 drives the information sensing strip 31 to slide past the magnetic sensor 232. The magnetic sensor 232 is used to sense the number and arrangement of the S-pole magnetic blocks 32 and N-pole magnetic blocks 33 of the information sensing strip 31 of the carrier 3 to mark the position and information of the carrier 3.

[0071] When the finished product is placed in the carrier 3, the magnetic sensor 232 can sense the number and arrangement of the S-pole magnetic blocks 32 and the N-pole magnetic blocks 33 of the information sensing strip 31 of the carrier 3 to locate the carrier 3 and register information, thereby facilitating the classification, storage and processing of the finished products in each carrier 3.

[0072] In some embodiments, the information sensing bar 31 has a plurality of the S-pole magnetic blocks 32 or the N-pole magnetic blocks 33 arranged in series. When the carrier 3 drives the information sensing bar 31 to slide past the magnetic sensor 232, the magnetic sensor 232 is used to mark the position and information of the carrier 3 by sensing the duration of the S-pole or N-pole magnetic field.

[0073] In some embodiments, the other end of the S-pole magnetic block 32 and the N-pole magnetic block 33 are opposite magnetic poles, that is, the other end of the S-pole magnetic block 32 is the N-pole magnetic field, and the other end of the N-pole magnetic block 33 is the S-pole magnetic field. The S-pole magnetic block 32 and the N-pole magnetic block 33 are rotatable and swingable, and the carrier supply line 27 is installed with an electromagnet, and the electromagnet is connected to a power supply unit that can output positive and negative electrical signals in a pulsed manner, so that when the information sensing bar 31 slides over the electromagnet, the electromagnet can drive each S-pole magnetic block 32 and N-pole magnetic block 33 in the information sensing bar 31 to swing, so as to edit the arrangement pattern of the S-pole magnetic block 32 and the N-pole magnetic block 33 of the information sensing bar 31, thereby realizing the numbering of the carriers.

[0078] The lower mold assembly 11 is provided with a bearing seat 111 for limiting and placing the first raw material plate. The bearing seat 111 is provided with a lower heating unit and a lower vacuum hole 112 for adsorbing the first raw material plate.

[0079] The upper mold component 12 is provided with an adsorption seat 121 for adsorbing the second raw material plate. The outer peripheral wall of the upper mold component 12 is rigidly connected with a movable groove seat 14, and the movable groove seat 14 is provided with a slide groove and is installed with a spring 141 and a cylinder 143.

[0080] The outer seat 15 slides in the slideway, and the outer seat 15 is in driving connection with the spring 141 and the cylinder 143.

[0082] Before the pressing power module 13 drives the lower mold component 11 and the upper mold component 12 to move closer and the first raw material plate and the second raw material plate are attached to each other, the cylinder 143 drives the outer seat 15 to press down and fit on the upper surface of the lower mold component 11, so that the first raw material plate and the second raw material plate are in the closed space 16. After that, the air pressure is increased in the closed space 16 through the exhaust pores to reduce the friction when the first raw material plate and the second raw material plate are aligned and attached to each other. At this time, the position of the second raw material plate can be adjusted by driving the adsorption seat 121 to move horizontally and vertically to align the second raw material plate with the first raw material plate. Before the pressing power module 13 drives the lower mold component 11 and the upper mold component 12 to move closer and the first raw material plate and the second raw material plate are superimposed to the finished product, the closed space 16 is evacuated through the exhaust pores to avoid gas remaining in the superimposed first raw material plate and the second raw material plate. After the first raw material plate and the second raw material plate are overlapped into the finished product, the cylinder 143 drives the outer seat 15 to separate from the lower metal mold component 11, and the pressing power module 13 drives the lower metal mold component 11 and the upper metal mold component 12 to open.

[0089] The material picking rack is installed with a supporting slide rail 21 and a shifting power module 22 located on both side plates of the lower metal mold component 11 and the upper metal mold component 12.

[0092] The following is a working description of an MLCC stacking device of this embodiment.

[0093] S1. Before the pressing power module 13 drives the lower mold component 11 and the upper mold component 12 to move closer and the first raw material plate and the second raw material plate are attached to each other, the cylinder 143 drives the outer seat 15 to press down and fit on the upper surface of the lower mold component 11, so that the first raw material plate and the second raw material plate are in the closed space 16. After that, the air pressure is increased in the closed space 16 through the exhaust pores to reduce the friction when the first raw material plate and the second raw material plate are aligned and attached to each other. At this time, the position of the second raw material plate can be adjusted by driving the adsorption seat 121 to move horizontally and vertically to align the second raw material plate with the first raw material plate. Before the pressing power module 13 drives the lower mold component 11 and the upper mold component 12 to move closer and the first raw material plate and the second raw material plate are superimposed to the finished product, the closed space 16 is evacuated through the exhaust pores to avoid gas remaining in the superimposed first raw material plate and the second raw material plate. After the first raw material plate and the second raw material plate are overlapped into the finished product, the cylinder 143 drives the outer seat 15 to separate from the lower metal mold assembly 11, and the pressing power module 13 drives the lower metal mold assembly 11 and the upper metal mold assembly 12 to open. At this time, the lower vacuum hole 112 stops adsorption, and the adsorption seat 121 adsorbs the finished product formed by the overlap of the first raw material plate and the second raw material plate to rise.

[0094] S2, at this time, the carrier 3 is placed on the material conveying line 231; the shift power module 22 drives the material conveying line 231 to move below the finished product, and at this time, the carrier 3 is also moved below the finished product; thereafter, the adsorption seat 121 descends and then stops adsorbing the finished product, so as to place the finished product in the carrier 3 on the material conveying line 231;

[0095] S3, during which the material-taking conveyor line 231 transfers the carrier 3 with the finished product through the lower docking channel 262 to the delivery conveyor line 25 for delivery, the carrier supply line 27 can supply another empty carrier 3 to the upper docking channel 262; after the material-taking conveyor line 231 transfers the carrier 3 with the finished product through the lower docking channel 262 to the delivery conveyor line 25, the lifting power module 26 drives the lifting frame 261 to rise and fall, and the lifting frame 261 drives the upper docking channel 262 with the empty carrier 3 to be spliced ​​with the material-taking conveyor line 231; thereafter, the material-taking conveyor line 231 takes the empty carrier 3 out of the docking channel 262 and uses it to move to the bottom of the next finished product to pick up the next finished product. During this period, the lifting power module 26 drives the lifting frame 261 to rise and fall and reset, so that the upper docking channel 262 moves the outlet of the carrier supply line 27 for splicing, and the lower docking channel 262 is spliced ​​with the material-taking conveyor line 231 and the delivery conveyor line 25.

[0096] In addition, after the carrier supply line 27 transports the carrier 3 to the docking platform and the inertia of the carrier 3 is moved out of the carrier supply line 27, a part of the carrier 3 will protrude from the docking platform. At this time, the lifting power module 26 drives the lifting frame 261 to lift and lower. When the lifting frame 261 drives the docking channel 262 with empty carriers 3 to be connected with the material taking conveyor line 231, the part of the carrier 3 protruding from the docking platform will fall onto the material taking conveyor line 231, so that the material taking conveyor line 231 can take out the empty carrier 3 on the docking platform; after the material taking conveyor line 231 transports the carrier 3 with finished products to the docking platform and the inertia of the carrier 3 is moved out of the carrier supply line 27, a part of the carrier 3 will protrude from the docking platform. At this time, a part of the carrier 3 will move to the delivery conveyor line 25, so that the delivery conveyor line 25 can take out the carrier 3 with finished products on the docking platform.

[0097] At the same time, when the material conveyor line 231 drives the carrier 3 to move, the carrier 3 drives the information sensing strip 31 to slide past the magnetic sensor 232. The magnetic sensor 232 senses the number and arrangement of the S-pole magnetic blocks 32 and the N-pole magnetic blocks 33 of the information sensing strip 31 of the carrier 3 to mark the position and information of the carrier 3. At the same time, the magnetic sensor 232 determines the number of two or more S-pole magnetic blocks 32 or N-pole magnetic blocks 33 that are attached to each other by sensing the duration of the S-pole or N-pole magnetic field, thereby realizing the registration and positioning of each carrier 3 and the finished products placed therein, so as to facilitate the subsequent workstations or equipment to classify and process the finished products in each carrier 3.
