Description

Technical Field

[0001] This invention relates to the field of degumming equipment technology, and specifically to a degumming device for polycrystalline diamond composite sheets after thinning. Background Technology

[0002] The standard industrial process for sintering and debinding diamond sheets (PCD / diamond green blanks) is to use a protected atmosphere to completely vaporize and decompose the molding binders such as paraffin / resin / polyvinyl alcohol (PVA) and remove them, thus avoiding residual carbon, pores, and cracks.

[0003] Commonly used small sintering devices, such as tubular atmosphere furnaces, typically involve manually adding diamond sheets into the furnace and then manually removing them with tools after debinding. However, these methods have drawbacks, such as low efficiency, high internal temperature after sintering, requiring waiting for the temperature to drop to a predetermined level before material removal, which is time-consuming and poses safety risks. Improvements are needed. Summary of the Invention

[0004] To address at least one of the aforementioned technical deficiencies, the present invention provides the following technical solution: This application discloses a device for degumming polycrystalline diamond composite sheets after thinning, including a sintering tank and a sealed cover, as well as a loading and unloading mechanism and a placing mechanism connected to the sintering tank. The material placement mechanism includes a placement plate and a storage cylinder connected to the placement plate for storing diamond composite sheets, with the placement plate supported by the sintering tank cavity wall; The loading and unloading mechanism includes a lifting mechanism, a rotating mechanism, and a clamping mechanism connected to the sintering tank. The moving end of the lifting mechanism is equipped with a rotating mechanism, and the output end of the rotating mechanism is equipped with a clamping mechanism. The clamping mechanism clamps the mounting plate. The lifting mechanism adjusts the longitudinal height of the loading mechanism to move it into or out of the sintering tank. The rotating mechanism reciprocates between the clamping mechanism and the loading mechanism above the sintering tank opening and outside the sintering tank.

[0005] In use, the clamping mechanism holds the mounting plate, and the diamond sheets are loaded into the storage cylinder. Then, the lifting mechanism moves the storage cylinder up until the bottom exceeds the height of the sintering tank opening. The rotating mechanism rotates to position the storage cylinder above the sintering tank opening, and the lifting mechanism moves down to support the mounting plate on the tank cavity wall. The clamping mechanism releases, and the lifting mechanism, in conjunction with the rotating mechanism, forms a combined clamping mechanism. After sintering and degumming are completed, the lifting mechanism, in conjunction with the rotating mechanism, clamps the mounting plate. Then, the lifting mechanism, in conjunction with the rotating mechanism, moves the material placement mechanism out of the sintering tank, removes the diamond sheets, and loads the next batch. This helps save manpower, improve efficiency, and enhance safety.

[0006] Furthermore, the clamping mechanism includes a telescopic mechanism, a first connecting rod, a second connecting rod, and a connecting head. The connecting head is located at the moving end of the telescopic mechanism. The first connecting rod is located on both sides of the connecting head. A gripper is provided at the first end of the first connecting rod, and its tail end is hinged to the telescopic mechanism. The second connecting rod is located between the first connecting rod and the connecting head. The first and tail ends of the second connecting rod are respectively hinged to the connecting head and the adjacent first connecting rod. The telescopic mechanism drives the connecting head to move longitudinally. Under the transmission of the second connecting rod, the first connecting rod is simultaneously merged or separated, correspondingly causing the gripper to merge or separate. Under the transmission of the second connecting rod, the telescopic mechanism drives the first connecting rod to merge or separate, facilitating the gripper to clamp or detach from the mounting plate.

[0007] Furthermore, the connector is T-shaped, with its longitudinal end connected to the moving end of the telescopic mechanism, and its two transverse ends hinged to the connecting rods for easy connection.

[0008] Furthermore, a support is provided on the peripheral wall of the sintering tank, a lifting mechanism is provided on the support, a support base is provided at the moving end of the lifting mechanism, and a rotating mechanism is provided on the support base to facilitate docking with the lifting mechanism.

[0009] Furthermore, the rotating mechanism includes a drive motor, a rotating column, and a transmission mechanism. The rotating column is pivotally connected to a support base and is driven to rotate by the drive motor under the transmission mechanism. A support plate is provided on the rotating column, and a clamping mechanism is provided on the support plate.

[0010] Furthermore, the storage cylinder includes an upper fixed plate, a lower fixed plate, and support rod one and support rod two. The lower fixed plate and the upper fixed plate are connected by support rod one and support rod two. Support rod one is distributed circumferentially around the storage cylinder, and an opening for material to enter and exit is formed between the two support rod ones. Support rod two is provided at the opening. Support rod two includes a rod body, a slider, and a locking block. A waist hole is provided on the slider along its length direction. The locking block includes a longitudinal body and a transverse body connected together. The longitudinal body is elastically telescopically connected to the upper fixed plate. A latch is provided at the end of the transverse body, and a corresponding locking groove is provided on the bottom surface of the slider. The longitudinal part passes through the waist hole. Support rod two can be rotated to disengage from the opening. Under normal conditions, support rod two blocks the opening to prevent diamond sheets from falling out of the opening. The opening can be opened by moving support rod two, thereby unloading or loading material.

[0011] Furthermore, a sliding post is provided on the bottom surface of the lower fixing plate, and a locking cover is slidably connected to the sliding post in the longitudinal direction. The locking cover has an insert post, and the sliding post passes through the waist hole of the lower slider. A slot that cooperates with the insert post is provided at the lower slider, thereby improving the stability of the second support rod.

[0012] Furthermore, annular protrusions are provided on the top side of the mounting plate, and insertion holes for the grippers are formed at intervals along the circumference of the protrusions to facilitate gripping by the grippers.

[0013] Compared with the prior art, the beneficial effects of the present invention are as follows: 1. The present invention improves the structure by adding a material feeding mechanism and a loading and unloading mechanism, which helps to improve safety and efficiency. Attached Figure Description

[0016] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0017] Example 1 like Figure 1 , Figure 2 As shown, in this example, a device for degumming polycrystalline diamond composite sheets after thinning includes a sintering tank 1 and a sealing cover 3, as well as a loading / unloading mechanism and a placing mechanism 6 connected to the sintering tank 1.

[0018] The material placement mechanism 6 includes a placement plate 61 and a storage cylinder connected to the placement plate 61 for storing diamond composite sheets, with the placement plate 61 supported by the cavity wall of the sintering tank 1. Specifically, as shown in Figures 1 and 2, the storage cylinder includes an upper fixed plate 68, a lower fixed plate 69, and support rods 64 and 74. The lower fixed plate 69 is connected to the upper fixed plate 68 by support rods 64 and 74. Three support rods 64 are spaced apart along the circumference of the storage cylinder and are arranged in a semi-circular shape. The upper part of support rod 64 is connected to the upper fixed plate 68, and the lower part of support rod 64 is connected to the lower fixed plate 69.

[0019] An opening (i.e., a semi-circular opening) for material entry and exit is formed between two support rods 64. Support rod 74 is installed at the opening. Support rod 74 includes a rod body 74, a slider 67, and a locking block. A waist hole 71 is formed along the length direction of the slider 67. The locking block includes a longitudinal body and a transverse body connected together. The longitudinal body and the transverse body are connected at the ends to form an L-shape. The longitudinal body is elastically telescopically connected to the upper fixed plate 68. For example, a groove is formed on the top surface of the upper fixed plate 68. The longitudinal body is located in the groove, and a spring is placed between the bottom surface of the longitudinal body and the bottom wall of the groove to form an elastic telescopic connection. The end of the transverse body is formed into a triangular shape, namely the latch 73. The bottom surface of the corresponding slider 67 is formed with a matching locking groove. The longitudinal part passes through the waist hole 71. The two are rotated and can move along the waist hole 71. In the normal state, the support rod 74 is in the opening to form a blockage and prevent the diamond sheet from falling out of the opening. At this time, the latch 73 is inserted into the locking groove to restrict the movement of the slider 67. Pressing down the locking post 72 will disengage the latch 73 from the locking groove to unlock. At this time, the support rod 74 can be moved radially outward along the storage cylinder. Then, the support rod 74 can be rotated to the side of the opening. Then, it can be loaded or unloaded. After that, the support rod 74 can be rotated to reset. Preferably, a positioning post is fixed on the upper fixed plate 68. When the support rod 74 is reset and moves to abut the positioning post, it cannot continue to rotate. At this time, it can be moved radially to insert the latch 73 at the slider 67 into the locking groove to lock.

[0020] In this example, a sliding post 75 is formed on the bottom surface of the lower fixed plate 69, and a locking cover 76 is slidably connected to the sliding post 75 along the longitudinal direction. A plug 77 is formed on one side of the locking cover 76. The sliding post 75 passes through the waist hole 71 at the lower slider 67. The slider 67 rotates relative to the sliding post 75 and moves along the waist hole 71. A slot is formed at the lower slider 67 to mate with the plug 77. The plug 77 and the slot are in an interference fit. The locking cover 76 moves up until the plug 77 is inserted into the slot to lock the slider 67. The interference fit between the plug 77 and the slot keeps the locking cover 76 in this position. The locking cover 76 can be moved down by force to disengage the plug 77 from the slot.

[0021] For fixing the storage cylinder to the mounting plate 61, the mounting plate 68 is connected to the mounting base 66, and the mounting base 66 is fixed to the mounting plate 61 by bolts 65. An annular flange 62 is formed on the top side of the mounting plate 61, and insertion holes 63 for the clamping claws 55 are formed at intervals along the circumference of the flange 62 to facilitate clamping by the clamping claws 55.

[0022] In this example, the loading and unloading mechanism includes a lifting mechanism 2, a rotating mechanism 4, and a clamping mechanism 5 connected to the sintering tank 1. A bracket 8 is fixed on one side of the sintering tank 1, and the lifting mechanism 2 is fixed on the bracket 8. The rotating mechanism 4 is installed at the moving end of the lifting mechanism 2, and the clamping mechanism 5 is installed at the output end of the rotating mechanism 4. The clamping mechanism 5 clamps the mounting plate 61. The lifting mechanism 2 is like a common telescopic cylinder. A support base 22 is horizontally installed at the telescopic end of the lifting mechanism 2, and the rotating mechanism 4 is installed on the support base 22. A guide mechanism 21 can be installed between the support base 22 and the bracket 8 to improve stability.

[0023] The rotating mechanism 4 includes a drive motor 43, a rotating column 41, and a transmission mechanism 42. The rotating column 41 is pivotally connected to the support base 22. Under the transmission of the transmission mechanism 42, the drive motor 43 drives the rotating column 41 to rotate. A horizontal fixed support plate 44 is fixed on the rotating column 41, and a clamping mechanism 5 is installed on the support plate 44. The transmission mechanism 42 is a common gear transmission type.

[0024] The clamping mechanism 5 includes a telescopic mechanism 51, a first connecting rod 53, a second connecting rod 54, and a connector 52. The connector 52 is fixed at the moving end of the telescopic mechanism 51. The telescopic mechanism 51 is like a common telescopic cylinder, and the cylinder body of the telescopic cylinder has a fixed flange 45.

[0025] Connecting rod 53 is located on both sides of connector 52. An L-shaped gripper 55 is fixed at the first end of connecting rod 53, and the tail end of connecting rod 53 is hinged to the flange 45 on the telescopic mechanism 51. Connecting rod 54 is located between connecting rod 53 and connector 52. The first and last ends of connecting rod 54 are respectively hinged to connector 52 and the middle of adjacent connecting rod 53. The telescopic mechanism 51 drives connector 52 to move longitudinally. Under the transmission of connecting rod 54, connecting rod 53 is simultaneously merged or separated, and the gripper 55 is merged or separated accordingly. When separated, the gripper 55 is inserted into the insertion hole 63 at the mounting plate 61 to form a lock.

[0026] In this example, connector 52 is T-shaped. The longitudinal end of connector 52 is connected to the moving end of telescopic mechanism 51, and the two ends of the horizontal part of connector 52 are respectively hinged to connecting rod 54.

[0027] In use, the clamping mechanism 5 clamps the mounting plate 61, and diamond sheets are loaded into the storage cylinder. Then, the lifting mechanism 2 moves the storage cylinder up until the bottom exceeds the height of the sintering tank 1 opening. The rotating mechanism 4 rotates so that the storage cylinder is above the opening of the sintering tank 1. The lifting mechanism 2 moves down to support the mounting plate 61 on the tank cavity wall, and the clamping mechanism 5 is released. The lifting mechanism 2, in conjunction with the rotating mechanism 4, resets the clamping mechanism 5. After sintering and degumming are completed, the lifting mechanism 2, in conjunction with the rotating mechanism 4, makes the clamping mechanism 5 clamp the mounting plate 61. Then, the lifting mechanism 2, in conjunction with the rotating mechanism 4, moves the material placement mechanism 6 out of the sintering tank 1, removes the diamond sheets, and loads the next batch. This helps save manpower and improve efficiency and safety.
