Description

Technical Field

[0001] This invention relates to the field of laminator technology, specifically to a multi-station laminator and its lamination process. Background Technology

[0002] A laminator is an industrial piece of equipment primarily used to bond two or more materials together to form composite materials. Laminators can be used in the manufacture of solar panels. The manufacturing process typically involves bonding two or more materials together under high temperature and pressure.

[0003] Currently, existing laminators typically have hot pressing and cooling stations to separately heat-press and cool raw materials. However, loading and unloading the laminator are usually done manually. After the workpiece is processed at the hot pressing station, its temperature is high, which can easily burn workers. Therefore, this manual unloading method poses a significant safety hazard, and the operation is inefficient and labor-intensive. To address this, the present invention provides a multi-station laminator and its lamination process. Summary of the Invention

[0004] The technical problem solved by this invention is that in the prior art, the loading and unloading of materials in the laminator is generally done manually. After the workpiece is processed in the hot pressing station, the workpiece itself is at a high temperature, which can easily burn the workers. Therefore, this manual unloading method has a great safety hazard, and the operation process is inefficient and labor-intensive.

[0005] This invention can be achieved through the following technical solution: a multi-station laminator, comprising a laminator body, a hot pressing station, and a cooling station. A machine platform is rotatably mounted inside the laminator body, driven by a second motor. The hot pressing station and the cooling station are symmetrically positioned above the machine platform. A feeding mechanism is located outside the laminator body, near the hot pressing station. A discharging mechanism is located inside the laminator body. The feeding mechanism is used to transport materials to the hot pressing station, and the discharging mechanism is used to output the material cooled by the cooling station from the laminator body.

[0006] A further technical improvement of the present invention is that: the feeding mechanism includes a support frame, a first electric cylinder is installed on one side of the support frame, a first push rod is fixedly connected to the output end of the first electric cylinder, and one end of the first push rod is in contact with the material; a second electric cylinder is installed at the bottom of the support frame, a second push rod is fixedly connected to the output end of the second electric cylinder, a placement plate is fixedly connected to the top end of the second push rod, and the material is stacked on the placement plate.

[0007] A further technical improvement of the present invention is that: the laminator body has a feeding groove on the side near the support frame, and the bottom of the feeding groove is flush with the machine platform; the support frame has a through groove on the side near the feeding groove.

[0008] A further technical improvement of the present invention is that: four positioning components are arranged around the top of the machine tool, and the positioning components include two positioning strips symmetrically slidably arranged on the top of the machine tool, and a limit block is fixed to one end of the positioning strip away from the center of the machine tool.

[0009] A further technical improvement of the present invention is that: the positioning component further includes a positioning block, a first hole is opened on one side of the positioning block, a slider is elastically slidably disposed in the first hole, and a trapezoidal groove is opened on the side of the slider near the positioning strip; the positioning block has a second hole in the vertical direction of the first hole, the second hole penetrates both sides of the positioning block, and a guide rod is fixedly connected to the side of the positioning strip near the positioning block, one end of the guide rod is slidably connected in the second hole, and one end of the guide rod is adapted to the shape of the trapezoidal groove; a second spring is fixedly connected between each positioning block and the positioning strip.

[0010] A further technical improvement of the present invention is that: the feeding mechanism includes a third push rod that passes through and is slidably connected to the top of the laminator body. The third push rod is driven by a hydraulic cylinder. A housing is fixed to the bottom end of the third push rod. A bidirectional screw is rotatably connected inside the housing. The bidirectional screw is driven by a first motor. Strip plates are sleeved at both ends of the bidirectional screw. The two strip plates pass through and are slidably connected to the bottom of the housing.

[0011] A further technical improvement of the present invention is that the feeding mechanism further includes a conveyor, a discharge trough is provided on one side of the laminator body, the conveyor is installed in the discharge trough, and the top of the conveyor is flush with the top of the machine platform.

[0012] The lamination process for a multi-station laminator, applicable to the aforementioned multi-station laminator, includes the following steps:

[0013] Step 1: Neatly stack the materials on top of the shelf. Drive the first push rod forward using the first electric cylinder, so that the first push rod pushes the top piece of material on the shelf into the machine platform inside the laminator.

[0014] Step 2: The hot pressing structure at the hot pressing station heats the material. Then, the second motor drives the machine to rotate, causing the material on the top of the machine to move to the cooling station below. The cooling structure at the cooling station cools the material after hot pressing.

[0015] Step 3: The second motor drives the machine to rotate, so that the material cooled on the top of the machine moves to the bottom of the unloading station. The hydraulic cylinder drives the third push rod to move downward, so that the two strip plates are located between the two positioning strips in the same group.

[0016] Step 4: The first motor drives the bidirectional screw to rotate, causing the two strip plates to move in opposite directions. This, combined with the elastic force of the first spring, causes the slider to bounce the material onto the top of the conveyor, allowing the material to be output from the conveyor, thus completing the feeding of the laminator.

[0017] Compared with the prior art, the present invention has the following beneficial effects:

[0018] 1. In this invention, a feeding mechanism and a discharging mechanism are provided to facilitate the feeding of the material at the top of the shelf into the laminator body. The second electric cylinder drives the second push rod and push plate to move upward, so that the bottom of the material at the top of the shelf is higher than or equal to the bottom of the through groove, which facilitates the next feeding of the laminator body. During discharging, the two strip plates are driven by the bidirectional screw to move in opposite directions, so that the two positioning strips move away from each other. At this time, with the elastic force of the first spring, the slider will bounce the material into the top of the conveyor, so that the material is output from the conveyor. No manual loading and unloading is required, which reduces safety hazards and improves production efficiency.

[0019] 2. In this invention, when the first pusher pushes the material into the top of the machine, the material box will contact one side of the slider, thus squeezing the slider and causing it to move forward. This causes the trapezoidal groove on the slider surface to move to the position of the second hole, allowing the end of the guide rod to insert into the trapezoidal groove under the action of the elasticity, thereby limiting the slider. At this time, one side of the material is in contact with the slider, while the other side is limited by the limiting block, so that the material is stably located at the top of the machine, preventing the material from sliding during hot pressing and reducing the lamination effect.

[0030] To further illustrate the technical means and effects of the present invention in achieving its intended purpose, the following detailed description of the specific implementation methods, structures, features, and effects of the present invention, in conjunction with the accompanying drawings and preferred embodiments, is provided.

[0031] Please see Figures 1-8 As shown, a multi-station laminator includes a laminator body 1, a hot pressing station, and a cooling station. A machine platform 2 is rotatably mounted inside the laminator body 1. The hot pressing station and the cooling station are symmetrically arranged above the machine platform 2. The machine platform 2 is driven by a second motor 25, which is fixedly installed on the bottom inner wall of the laminator body 1. The second motor 25 drives the machine platform 2 to rotate, so that the material on the top of the machine platform 2 is transferred to the corresponding hot pressing station and the cooling station below. A feeding mechanism is provided on the outside of the laminator body 1, and the feeding mechanism is located on the side close to the hot pressing station. A discharging mechanism is provided inside the laminator body 1.

[0032] The feeding mechanism is used to transport materials to the hot pressing station. The feeding mechanism includes a support frame 3. A first electric cylinder 4 is fixedly installed on one side of the support frame 3. The first electric cylinder 4 is used to push the material into the laminator body 1 and make it exactly below the hot pressing station. A first push rod is fixedly connected to the output end of the first electric cylinder 4, and one end of the first push rod is in contact with the material. A second electric cylinder 5 is fixedly installed at the bottom of the support frame 3. A second push rod is fixedly connected to the output end of the second electric cylinder 5. A placement plate 6 is fixedly connected to the top of the second push rod, and the material is stacked on the placement plate 6. The laminator body 1 has a feeding groove 8 on the side near the support frame 3, and the bottom of the feeding groove 8 is flush with the machine base 2. A through groove 7 is opened on the side of the support frame 3 near the feeding groove 8, and a sponge block is fixedly connected to the top of the through groove 7.

[0033] When the feeding mechanism is working, it first neatly stacks the material on top of the shelf plate 6, ensuring that the bottom of the topmost piece of material is flush with or higher than the bottom of the through groove 7. This ensures that the material can be pushed into the through groove 7 and enter the machine base 2 inside the laminator body 1 through the feed chute 8. Then, by activating the first electric cylinder 4, the first electric cylinder 4 drives the first push rod forward, causing the first push rod to push the topmost piece of material on the shelf plate 6 into the through groove 7, the discharge chute 22, and into the machine base 2 inside the laminator body 1. After the first piece of material on the top of the shelf plate 6 is fed into the laminator body 1, the second electric cylinder drives the second push rod and the push plate upward, so that the bottom of the topmost piece of material on the shelf plate 6 is higher than or equal to the bottom of the through groove 7, facilitating the next feeding of the laminator body 1.

[0034] To achieve material positioning, four positioning components are arranged around the top of the machine platform 2. The positioning components include four positioning blocks 9 and eight positioning strips 10. The eight positioning strips 10 are arranged in pairs, and the two positioning strips 10 in each pair are symmetrically slidably arranged on the top of the machine platform 2. A limit block 11 is fixed to the end of the positioning strip 10 away from the center of the machine platform 2. A first hole is opened on one side of the positioning block 9, and a slider 12 is slidably connected in the first hole. A first spring 13 is fixed to one side of the slider 12, and the other end of the first spring 13 is fixed to the inner wall of the first hole. A trapezoidal groove 24 is opened on the side of the slider 12 near the positioning strip 10. A second hole is opened in the vertical direction of the first hole of the positioning block 9. The second hole passes through both sides of the positioning block 9. A guide rod 14 is fixed to the side of the positioning strip 10 near the positioning block 9. One end of the guide rod 14 is slidably connected in the second hole, and the shape of the guide rod 14 is adapted to the trapezoidal groove 24. A second spring 23 is fixed between each positioning block 9 and the positioning strip 10.

[0035] Before the material enters the top of the machine platform 2, the ends of the two guide rods 14 are not in the trapezoidal groove 24, and the ends of the guide rods 14 are against the side wall of the slider 12. At this time, the distance between the two positioning bars 10 and the distance between the limiting blocks 11 at their ends are sufficient to insert the material. At this time, the second spring 23 is also in a stretched state. In the above positioning assembly, when the first push rod pushes the material into the top of the machine platform 2, it will cause the material box to contact one side of the slider 12, thereby squeezing the slider 12 and causing the slider 12 to move forward. This causes the trapezoidal groove 24 on the surface of the slider 12 to move to the position of the second hole along with the slider 12, so that the end of the guide rod 14 is inserted into the trapezoidal groove 24 under the action of elastic force, thereby limiting the slider 12. At this time, the first spring 13 is in a compressed state. One side of the material is in contact with the slider 12, and the other side is limited by the limiting block 11. The material is stably located at the top of the machine platform 2.

[0036] The feeding mechanism is used to output the material cooled by the cooling station from the laminator body 1. The feeding mechanism includes a conveyor 15 and a third push rod 16. The third push rod 16 is slidably connected to the top of the laminator body 1 and is driven by a hydraulic cylinder 17. The bottom end of the third push rod 16 is fixed to a housing 18. A bidirectional screw 19 is rotatably connected inside the housing 18 and is driven by a first motor 20. Strip plates 21 are sleeved at both ends of the bidirectional screw 19 and are slidably connected to the bottom of the housing 18. A discharge chute 22 is opened on one side of the laminator body 1. The conveyor 15 is installed in the discharge chute 22 and the top of the conveyor 15 is flush with the top of the machine platform 2.

[0037] When using the feeding mechanism, the second motor 25 needs to be started first, so that the second motor 25 can transfer the material located under the cooling station to the bottom of the feeding station. Specifically, the second motor 25 drives the machine platform 2 to rotate, so that the material on the top of the machine platform 2 moves to the bottom of the feeding station. At this time, the hydraulic cylinder 17 drives the third push rod 16 to move downward, so that the two strip plates 21 are located between the two positioning bars 10 in the same group. Then, the first motor 20 is started, so that the first motor 20 drives the bidirectional screw 19 to rotate. The bidirectional screw 19 drives the two strip plates 21 to move in opposite directions, so that the two positioning bars 10 move away from each other. At this time, with the elastic force of the first spring 13, the slider 12 will return to the initial position and the material will be bounced into the top of the conveyor 15, so that the material is output from the conveyor 15, completing the feeding of the laminator.

[0038] The lamination process for a multi-station laminator, applicable to the aforementioned multi-station laminator, includes the following steps:

[0039] Step 1: Arrange the materials neatly on the top of the shelf 6. Drive the first push rod forward through the first electric cylinder 4, so that the first push rod pushes the top piece of material on the shelf 6 into the machine platform 2 inside the laminator body 1.

[0040] Step 2: The hot pressing structure at the hot pressing station heats the material. Then, the second motor 25 drives the machine 2 to rotate, causing the material on the top of the machine 2 to move to the cooling station below. The cooling structure at the cooling station cools the material after hot pressing.

[0041] Step 3: The second motor 25 drives the machine platform 2 to rotate, so that the material cooled on the top of the machine platform 2 moves to the bottom of the unloading station. The hydraulic cylinder 17 drives the third push rod 16 to move downward, so that the two strip plates 21 are located between the two positioning strips 10 in the same group.

[0042] Step 4: The first motor 20 drives the bidirectional screw 19 to rotate, causing the two strip plates 21 to move in opposite directions. As a result, the two positioning strips 10 move away from each other. Combined with the elastic force of the first spring 13, the slider 12 will bounce the material into the top of the conveyor 15, so that the material is output from the conveyor 15, completing the feeding of the laminator.

[0043] In use, the materials are first neatly stacked on top of the shelf 6, with the bottom of the topmost piece of material flush with or higher than the bottom of the channel 7, ensuring that the material can be pushed into the channel 7 and enter the machine base 2 inside the laminator body 1 through the feed chute 8. Then, by activating the first electric cylinder 4, the first electric cylinder 4 drives the first push rod forward, causing the first push rod to push the topmost piece of material on the shelf 6 into the channel 7, the discharge chute 22, and into the machine base 2 inside the laminator body 1. When the topmost piece of material on the shelf 6... After a piece of material is fed into the laminator body 1, the second electric cylinder drives the second push rod and push plate to move upward, so that the bottom of the topmost piece of material on the top of the shelf 6 is higher than or equal to the bottom of the through groove 7, facilitating the next feeding of the laminator body 1; when the first push rod pushes the material into the top of the machine platform 2, it will cause the material box to contact one side of the slider 12, compressing the slider 12 and causing the slider 12 to move forward. This causes the trapezoidal groove 24 on the surface of the slider 12 to move to the position of the second hole, so that the end of the guide rod 14 is under the action of the elasticity. Inserted into the trapezoidal groove 24, the slider 12 is limited, while the first spring 13 is in a compressed state; one side of the material contacts the slider 12, and the other side is limited by the limiting block 11, so the material is stably located at the top of the machine platform 2; then the hot pressing structure on the hot pressing station hot presses the material, and then the second motor 25 drives the machine platform 2 to rotate, so that the material at the top of the machine platform 2 moves to the cooling station below, and the cooling structure on the cooling station cools the material after hot pressing; when unloading, the second motor 25 needs to be started first, so that the second motor 25 drives the machine platform 2 to rotate, so that the material at the top of the machine platform 2 moves to the cooling station below, and the cooling structure on the cooling station cools the material after hot pressing; when unloading, the second motor 25 needs to be started first, so that the second motor 25 drives the machine platform 2 to rotate, so that the material at the top of the machine platform 2 moves to the cooling station below, and the cooling structure on the cooling station cools the material after hot pressing; The material in the part moves to the bottom of the unloading station. At this time, the hydraulic cylinder 17 drives the third push rod 16 to move downward, so that the two strip plates 21 are located between the two positioning bars 10 in the same group. Then the first motor 20 is started, so that the first motor 20 drives the bidirectional screw 19 to rotate. The bidirectional screw 19 drives the two strip plates 21 to move in opposite directions, so that the two positioning bars 10 move away from each other. At this time, with the elastic force of the first spring 13, the slider 12 will return to the initial position and the material will be bounced into the top of the conveyor 15, so that the material is output from the conveyor 15, completing the unloading of the laminator.
