Description

Technical Field

[0001] This utility model belongs to the technical field of feeding cylinder pull rod in monocrystalline silicon manufacturing process, specifically relating to an automatic locking buckle device for feeding. Background Technology

[0002] With the development of monocrystalline silicon preparation, the operating time of a single furnace for RCZ (Rock Cell Pulling) monocrystalline silicon has now reached over 500 hours. During operation, the number of times the secondary feeder is used to add material during a single operation is as high as 9 or 10 times, with 5 cylinders added each time. The number of cylinders added per furnace is 45-50, and the material adding process accounts for more than half of the total manual labor in crystal pulling. Currently, there are two main types of operators in crystal pulling production sites: ① crystal pulling main operators and ② material hanging operators. According to the current industry level, crystal pulling can achieve digitalization, with operators remotely managing 90 or 200 (one person oversees 90 / 200 monocrystalline furnaces), eliminating the need for a single crystal pulling operator on the production line and achieving fully remote crystal pulling. However, for improving the efficiency of material hanging operators, due to insufficient digitalization, the rigid conditions of the production line, and the original design of the tooling fixtures, it is impossible to eliminate the need for on-site manual operation, and there is no substitute.

[0003] The existing feeder chuck uses a pin-type locking mechanism. During feeding, personnel must stand on the feeding trolley, pull out the pin from the chuck, align the herringbone hole with the flat hole on the feeder, and then insert the pin to lock the herringbone and flat holes together. Each time the feeder needs to be engaged or disengaged—that is, locked or loosened—manual loading and unloading of the feeder trolley is required to perform the pin-locking process. This is inefficient, time-consuming, and labor-intensive, and poses a safety hazard to personnel when loading and unloading the trolley. Summary of the Invention

[0004] This utility model provides an automatic locking buckle device for feeding, which aims to solve the problem that the existing feeder clamps require manual operation of the loading and unloading trolley to insert pins each time they lock or loosen the feeder, which is wasteful of manpower, time-consuming and labor-intensive, and poses certain safety hazards.

[0005] This utility model embodiment provides an automatic locking and feeding buckle device, including a clamp, a feeder cylinder is provided below the clamp, a pull rod is provided in the feeder cylinder, the upper end of the pull rod extends into the clamp, a hanging cap is fixedly connected to the top of the pull rod, an anti-slip rod is provided on the pull rod, a slider is provided between the hanging cap and the anti-slip rod, the slider is slidably sleeved on the pull rod, and a plurality of buckles are provided in the clamp, the buckles being slidably connected to the clamp through a sliding component.

[0006] Furthermore, both the pendant cap and the slider are frustum-shaped structures, and the diameter of the upper surface of the slider is larger than the diameter of the lower surface of the pendant cap.

[0007] Furthermore, an inner cavity is formed on the bottom wall of the clamp, and a number of grooves are formed on the outer wall of the clamp. The grooves communicate with the inner cavity, and the number of grooves is the same as the number of buckles.

[0008] Furthermore, the number of the latches is two.

[0009] Furthermore, the sliding assembly includes a limiting block slidably connected in the groove, one end of the buckle is fixedly connected to the limiting block, the other end face of the limiting block is fixedly connected to a spring, the other end of the spring abuts against a blocking block, the blocking block is threadedly connected to the inner wall of the groove, and a slot is provided on the outer wall of the blocking block.

[0010] Furthermore, the cross-section of the limiting block is convex.

[0011] Furthermore, the anti-slip rod includes a rotating head and a screw that are fixedly connected, the screw being threadedly connected to the pull rod, and the outer surface of the rotating head being provided with anti-slip texture.

[0012] Furthermore, the top wall of the chuck is provided with a top groove, and the inner wall of the top groove is provided with an internal thread.

[0013] The beneficial effects of this utility model are as follows:

[0014] This utility model utilizes the inclined guiding effect of the hanging cap, slider, and buckle, as well as the spring extension and recovery effect, to meet the interaction and cooperation of multiple contact points of the hanging cap, slider, and buckle during the descent of the external weight. This achieves the function of automatic structural locking and loosening, realizing the action of hanging and unloading the feeder. It eliminates the manual process of inserting pins on the loading and unloading trolley of the material cylinder, improves personnel efficiency, saves time and labor, and reduces safety hazards.

[0022] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. The same reference numerals in the drawings represent the same components. It should be noted that the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the described embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0023] Reference Figure 1-4 This utility model embodiment proposes an automatic locking and feeding buckle device, including a clamp 1, a feeder cylinder 2 is arranged below the clamp 1, a pull rod 3 is arranged in the feeder cylinder 2, the upper end of the pull rod 3 extends into the clamp 1, a hanging cap 4 is fixedly connected to the top of the pull rod 3, an anti-slip rod 5 is arranged on the pull rod 3, a slider 6 is arranged between the hanging cap 4 and the anti-slip rod 5, the slider 6 is slidably sleeved on the pull rod 3, and a plurality of buckles 7 are arranged in the clamp 1, the buckles 7 being slidably connected to the clamp 1 through a sliding component 8.

[0024] Both the pendant cap 4 and the slider 6 are frustum structures, with the upper diameter of the slider 6 being larger than the lower diameter of the pendant cap 4.

[0025] Specifically, the diameter of the pendant cap 4 gradually increases from top to bottom, while the diameter of the slider 6 gradually decreases from top to bottom. The diameter of the upper surface of the slider 6 is larger than the diameter of the lower surface of the pendant cap 4. The slider 6 is made of lightweight and high-temperature resistant PTFE material and can move axially up and down and rotate on the pull rod 3. The buckle 7 is a right-angled trapezoidal three-dimensional structure. The fulcrum on the inclined surface of the buckle 7 is provided with an arc-shaped chamfer. When locking the feeder, as the chuck 1 descends, the upper end of the pull rod 3 enters the inner cavity 101. When the buckle 7 is engaged between the pendant cap 4 and the slider 6, the height of the upper surface of the buckle 7 is lower than the height of the lower surface of the pendant cap 4, and the edge of the upper surface of the slider 6 is located below the inclined surface of the buckle 7. When the chuck 1 descends or rises, the buckle 7 forms a sliding guide engagement with the pendant cap 4 and the slider 6. When the slider 6 is in sliding engagement with the buckle 7, the slider 6 can move axially up and down on the pull rod 3.

[0026] An inner cavity 101 is formed on the bottom wall of the chuck 1, and several grooves 102 are formed on the outer wall of the chuck 1. The grooves 102 communicate with the inner cavity 101, and the number of grooves 102 is the same as the number of latches 7. There are two latches 7 to facilitate stable locking of the feeder.

[0027] The sliding component 8 includes a limiting block 801 slidably connected in the groove 102. The limiting block 801 has a "convex" cross-section to prevent the limiting block 801 and the buckle 7 from disengaging from the groove 102. One end of the buckle 7 is fixedly connected to the limiting block 801, and the other end of the limiting block 801 is fixedly connected to a spring 802. The other end of the spring 802 abuts against a blocking block 803. The blocking block 803 is threadedly connected to the inner wall of the groove 102. A slot is provided on the outer side wall of the blocking block 803 to facilitate the disassembly and installation of the blocking block 803. The spring 802 facilitates the retraction and extension reset of the buckle 7, realizing the sliding guide cooperation between the buckle 7, the hanging cap 4, and the slider 6.

[0028] The anti-slip rod 5 includes a rotating head 501 and a screw 502 that are fixedly connected. The screw 502 is threadedly connected to the pull rod 3. The outer surface of the rotating head 501 is provided with anti-slip texture to facilitate the installation of the anti-slip rod 5. The anti-slip rod 5 is used to limit the movement of the slider 6.

[0029] The top wall of the chuck 1 has a top groove 103, and the inner wall of the top groove 103 has an internal thread. The top groove 103 is used to connect an external counterweight.

[0030] The specific implementation method is as follows: When in use, the feeder cylinder 2 is clamped and fixed on the single crystal furnace, and the top of the chuck 1 is connected to a counterweight. The counterweight drives the chuck 1 to rise and fall, and the distance of the counterweight rising and falling is limited by the external host system.

[0031] As the weighted hammer descends, the top of the lever 3 enters the clamp 1. During the descent, because the weight of the hammer is greater than the elastic force of the spring 802 on the buckle 7, the hammer descends. The buckle 7 is guided by the inclined surface of the hanging cap 4, causing the spring 802 to compress. The buckle 7 moves to both ends, and the clamp 1 continues to descend. When the lower plane of the hanging cap 4 is aligned with the upper plane of the buckle 7, the fulcrum on the inclined surface of the buckle 7 completely separates from the inclined surface of the hanging cap 4. The spring 802 returns to its original state after compression, and the upper plane of the buckle 7 contacts the lower plane of the hanging cap 4. The hammer then rises again, and the upper plane of the buckle 7 exerts an upward lifting force on the lower plane of the hanging cap 4, forming a locking structure and completing the feeding device hanging action.

[0032] After feeding is completed, when the feeder is unloaded, the slider 6 is stopped due to the anti-slip rod 5. Then the weight is lowered to the position of the counterweight. The inclined surface of the buckle 7 contacts the edge of the upper plane of the slider 6, which compresses the spring 802. The buckle 7 moves to both ends, and the clamp 1 continues to descend. The fulcrum on the inclined surface of the buckle 7 contacts the inclined surface of the slider 6 through the edge of the upper plane of the slider 6. The spring 802 returns to its original position. Because the slider 6 is light, it automatically moves upward when sliding with the buckle 7. At the same time, the weight is controlled to be lifted quickly. By using the deviation between the diameter of the upper plane of the slider 6 and the diameter of the lower plane of the hanging cap 4, and the guiding effect of the inclined surface of the buckle 7, the gap between the hanging cap 4 and the slider 6 is avoided, and the separation of the hanging cap 4 and the buckle 7 is completed, thus completing the unloading action of the feeder.

[0033] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims.
