Description

Technical Field

[0001] The present invention relates to the technical field of graphite boats, and more specifically to an automatic assembly device for graphite boat gaskets. Background Art

[0002] A graphite boat is a graphite mold. The graphite mold itself is a carrier. Raw materials and components that need to be positioned or shaped can be placed together in the graphite mold and sintered at high temperature. The graphite mold is made of artificial graphite through machining, thus called a graphite boat. The graphite boat gasket is also one of the essential accessories on the graphite boat sheet. Currently, the existing graphite boat gaskets are usually manually placed one by one into the graphite boat sheet and then embedded and pressed by a pressing machine.

[0003] However, at present, most of the assembly of existing graphite boat gaskets is completed by manual operation, with low production efficiency, long labor hours, and high labor intensity for workers. At the same time, there may also be problems of missing installation and misinstallation. Summary of the Invention

[0004] The purpose of the present invention is to provide an automatic assembly device for graphite boat gaskets in view of the deficiencies of the prior art. By setting a conveyor belt and a rotary chain, since their transmission speeds are the same, the graphite boat gaskets and the holes on the graphite boat sheet correspond one by one during the transmission process, improving the assembly accuracy, reducing manual consumption, and lowering production costs. In addition, by setting a feeding component and a material taking component, the automatic feeding, automatic material taking, and automatic discharging operations of the graphite boat gaskets can be quickly realized, without manual operation, improving production efficiency and reducing operation hours.

[0005] The technical solution of the present invention is as follows:

[0006] An automatic assembly device for graphite boat gaskets includes a frame. A conveyor belt is arranged on the frame. A rotary component is arranged above the conveyor belt. A plurality of material taking components are arrayed on the rotary component. The material taking component includes a rotatable arc-shaped clamp. A pre-assembly channel is formed between the lower end of the rotary component and the conveyor belt. A guide rail is arranged on the moving path of the rotary component. A feeding component is also arranged above the rotary component. The conveyor belt is used to transport the graphite boat sheet. After the rotatable arc-shaped clamp passes through the feeding component to complete the clamping of the graphite boat gasket, the graphite boat gasket and the holes on the graphite boat sheet correspond one by one when passing through the pre-assembly channel during the transmission. The guide rail is used to cooperate with the material taking component to pre-assemble the graphite boat gasket onto the graphite boat sheet.

[0007] As a preference, the rotary component includes a rotary chain and a support rod.

[0008] As a preference, the material taking component further includes a fixed section and a telescopic section, and a return spring is connected between the fixed section and the telescopic section. A connecting rod is arranged on the return spring, and a gear rotatably arranged on the connecting rod.

[0009] As a preference, the feeding component includes a conveyor belt, baffles arranged on both sides of the conveyor belt, and loading platforms a and b arranged at the front end of the conveyor belt. An empty slot is arranged between the loading platforms a and b.

[0010] As a preference, a rack is further arranged on the moving path of the rotary component, and the rack meshes with the gear.

[0011] As a preference, a transfer table is further arranged at the right end of the conveyor belt. An assembly table is arranged behind the transfer table. A push cylinder, a lead screw driven by the push cylinder, and a top push plate connected to the lead screw are arranged at the front end of the transfer table. A limiting plate a is arranged on the right side of the transfer table. A conveyor belt is arranged on the assembly table. A limiting plate b is arranged on the left side of the conveyor belt, and a pressing machine is arranged above the right of the conveyor belt.

[0012] As a preference, a chute is further opened at the inner end of the guide rail.

[0013] As a preference, a slider is arranged at the outer end of the rotatable arc-shaped fixture, and the slider moves along the chute.

[0014] As a preference, a groove is opened on the inner wall of the rotatable arc-shaped fixture, and the groove cooperates with the protrusion on the outer wall of the graphite boat gasket.

[0015] As another preference, a plurality of telescopic rods are further arranged on the inner side of the upper end of the rotatable arc-shaped fixture.

[0016] The beneficial effects of the present invention are as follows:

[0017] The present invention is provided with a conveyor belt and a rotary component. On the one hand, the conveyor belt can convey the graphite boat sheets to the pre-assembly position, improving the operation efficiency. On the other hand, since the transmission speeds of the conveyor belt and the rotary chain are the same, when the rotatable arc-shaped fixture passes through the feeding component to complete the clamping of the graphite boat gasket and then passes through the pre-assembly channel during transmission, the holes on the graphite boat gasket and the graphite boat sheets correspond one by one, improving the assembly accuracy and effectively solving the problems of missing installation and misinstallation of the graphite boat gasket.

[0018] The present invention is provided with a material taking component and a feeding component. While the feeding component is feeding, the rotatable arc-shaped fixture follows the rotary chain and clamps the graphite boat gasket through the empty slot during transmission. This process realizes the operations of automatic feeding, automatic material taking and automatic blanking of the graphite boat gasket, improves the production efficiency and reduces the operation man-hours.

[0019] The present invention is also provided with a guide rail. After the material taking component enters the guide rail, the material taking component is pressed under the guiding action of the guide rail, and the graphite boat washer is pre-assembled onto the graphite boat sheet through the telescopic section, solving the problem that the graphite boat washers need to be manually placed on the graphite boat sheets one by one, reducing the manual labor consumption. In addition, since the graphite boat washers are small in volume and difficult to pick up manually, this device also reduces the operation difficulty.

[0020] In summary, the present invention has functions such as automatic material taking, automatic feeding, and automatic assembly, and is suitable for the technical field of graphite boats. Brief Description of the Drawings

[0029] The following clearly and completely describes the technical solutions in the embodiments of the present invention with reference to the drawings.

[0030] Embodiment 1

[0031] The following details the embodiments of the present invention. The examples of the embodiments are shown in the drawings, where the same or similar reference numerals represent the same or similar elements or elements with the same or similar functions from beginning to end. The embodiments described below with reference to the drawings are exemplary and are intended to explain the present invention and should not be construed as limiting the present invention.

[0032] As Figures 1 to 7As shown in the figure, an automatic assembly device for graphite boat gaskets includes a frame 1. A conveyor belt 11 is arranged on the frame 1. Above the conveyor belt 11, a rotary assembly 2 is arranged. A number of material taking assemblies 3 are arrayed on the rotary assembly 2. The material taking assembly 3 includes a rotatable arc-shaped fixture 31. A pre-assembly channel 4 is formed between the lower end of the rotary assembly 2 and the conveyor belt 11. A guide rail 5 is arranged on the moving path of the rotary assembly 2. A feeding assembly 6 is also arranged above the rotary assembly 2. The conveyor belt 11 is used to transport graphite boat plates 7. After the rotatable arc-shaped fixture 31 passes through the feeding assembly 6 to complete the clamping of the graphite boat gasket 71, when it passes through the pre-assembly channel 4, the holes 72 on the graphite boat gasket 71 and the graphite boat plate 7 are in one-to-one correspondence. The guide rail 5 is used to cooperate with the material taking assembly 3 to pre-assemble the graphite boat gasket 71 onto the graphite boat plate 7.

[0033] As Figure 1 shown in the figure, the rotary assembly 2 includes a rotary chain 21 and a support rod 22.

[0034] It is worth mentioning that the present invention is provided with a conveyor belt 11 and a rotary assembly 2. On the one hand, the conveyor belt 11 can transport the graphite boat plate 7 to the pre-assembly position, improving the operation efficiency. On the other hand, since the transmission speeds of the conveyor belt 11 and the rotary chain 21 are the same, after the rotatable arc-shaped fixture 31 passes through the feeding assembly 6 to complete the clamping of the graphite boat gasket 71, when it passes through the pre-assembly channel, the holes 72 on the graphite boat gasket 71 and the graphite boat plate 7 are in one-to-one correspondence, improving the assembly accuracy and effectively solving the problems of missing installation and misinstallation of the graphite boat gasket 71.

[0035] As Figure 2 and Figure 3 shown in the figure, the material taking assembly 3 further includes a fixed section 32 and a telescopic section 33. A return spring 34 is connected between the fixed section 32 and the telescopic section 33. A connecting rod 35 is arranged on the return spring 34, and a gear 36 rotatably arranged on the connecting rod 35.

[0036] As Figure 4 shown in the figure, the feeding assembly 6 includes a conveyor belt 61, baffles 62 arranged on both sides of the conveyor belt 61, and a carrier table a 63 and a carrier table b 64 arranged at the front end of the conveyor belt 61. An empty slot 65 is arranged between the carrier table a 63 and the carrier table b 64.

[0037] It should be further noted that the present invention is also provided with a material taking assembly 3 and a feeding assembly 6. While the feeding assembly 6 is feeding, the rotatable arc-shaped fixture 31 follows the rotary chain 21 and clamps the graphite boat gasket 71 through the empty slot 65 during the transmission process. This process realizes the operations of automatic feeding, automatic material taking and automatic blanking of the graphite boat gasket 71, improving the production efficiency and reducing the operation man-hours.

[0038] As Figure 1As shown in the figure, a rack 8 is further provided on the moving path of the rotary assembly 2, and the rack 8 meshes with the gear 35. When the gear 36 rotates, it drives the rotatable arc-shaped fixture 31 to rotate, so that the graphite boat washer 71 is aligned with the hole 72 on the graphite boat sheet 7 in the correct placement direction.

[0039] As Figure 6 shown in the figure, a transfer table 12 is further provided at the right end of the conveyor belt 11. An assembly table 13 is provided behind the transfer table 12. A push cylinder 121, a lead screw 122 driven by the push cylinder 121, and a push plate 123 connected to the lead screw 122 are provided at the front end of the transfer table 12. A limit plate a 124 is provided on the right side of the transfer table 12. A conveyor belt 131 is provided on the assembly table 13. A limit plate b 132 is provided on the left side of the conveyor belt 131, and a press 133 is provided above the right side of the conveyor belt 131.

[0040] As Figure 5 shown in the figure, a chute 51 is further opened at the inner end of the guide rail 5.

[0041] In addition, the present invention is also provided with a guide rail 5. After the material taking assembly 3 enters the chute 51 of the guide rail 5, the guide rail 5 presses the material taking assembly 3. By setting the telescopic section 32, the graphite boat washer 71 is pre-assembled onto the graphite boat sheet 7, solving the problem of manually placing the graphite boat washers 71 onto the graphite boat sheets 7 one by one, reducing the manual consumption. In addition, since the graphite boat washer 71 is small in volume and difficult to pick up manually, this device also reduces the operation difficulty.

[0042] As Figure 2 shown in the figure, a slider 37 is provided at the outer end of the rotatable arc-shaped fixture 31, and the slider 37 moves along the chute 51. By setting the slider 37, the rotatable arc-shaped fixture 31 is prevented from getting stuck in the guide rail 5.

[0043] As Figure 2 shown in the figure, a groove 38 is opened on the inner wall of the rotatable arc-shaped fixture 31, and the groove 38 cooperates with the protrusion 73 on the outer wall of the graphite boat washer 71, so that the rotatable arc-shaped fixture 31 can clamp the graphite boat washer 71 more firmly, avoiding the problem of falling during rotation.

[0044] As Figure 3 shown in the figure, a plurality of telescopic rods 39 are further provided inside the upper end of the rotatable arc-shaped fixture 31 to prevent the lower edge of the rotatable arc-shaped fixture 31 from colliding with the graphite boat sheet 7 when the rotatable arc-shaped fixture 31 places the graphite boat washer 71, and keeping a distance from the graphite boat sheet 7 through the telescopic rods 39.

[0045] Embodiment 2

[0046] As Figure 2As shown in the figure, components that are the same as or corresponding to those in the first embodiment are denoted by the corresponding reference numerals in the first embodiment. For the sake of simplicity, only the differences from the first embodiment will be described below; the difference between the second embodiment and the first embodiment lies in that the inner wall of the rotatable arc-shaped clamp 31 is composed of a flexible material.

[0047] Here, in this embodiment, by arranging a flexible material on the inner wall of the rotatable arc-shaped clamp 31, a surface contact is formed between the rotatable arc-shaped clamp 31 and the graphite boat gasket 71 when clamping, effectively reducing the deformation of the graphite boat gasket 71 after being clamped.

[0048] Working process

[0049] First, the worker places the graphite boat sheet 7 on the conveyor belt 11. The conveyor belt 61 in the feeding assembly 6 conveys the graphite boat gasket 71 to the loading platforms a63 and b64, and the baffles 62 arranged on both sides of the conveyor belt 61 limit the graphite boat gasket 71 to prevent the possibility of displacement of the graphite boat gasket 71 during transportation. While the conveyor belt 61 is conveying, the material taking assembly 3 also rotates along with the rotary chain 21 to reach the feeding assembly 6. After the rotatable arc-shaped clamp 31 clamps the graphite boat gasket 71 through the empty slot 65, the rotatable arc-shaped clamp 31 is rotated 90 degrees backward by the engagement of the gear 36 and the rack 8. When the material taking assembly 3 rotates to the lower end of the rotary chain 21, it enters the guide rail 5. Under the guiding action of the guide rail 5, the material taking assembly 3 is pressed, and the graphite boat gasket 71 is pre-assembled onto the graphite boat sheet 7 by setting the telescopic section 32. After leaving the guide rail 5, the rotatable arc-shaped clamp 31 is restored to its original state by setting the return spring 34. Thereafter, the pre-assembled graphite boat sheet 7 enters the transfer table 12 through the pre-assembly channel 4 and is limited by the limiting plate a124 arranged on the right side of the transfer table 12 to prevent the graphite boat sheet 7 from slipping. The graphite boat sheet 7 is pushed to the assembly table 13 by setting the push plate 123, and is limited by the limiting plate b132 arranged on the left side of the conveyor belt 131, and the graphite boat sheet 7 is conveyed by the conveyor belt 131 to the lower part of the press 133 for the final assembly work.
