Description

Technical Field

[0001] This invention relates to preform processing equipment, and more particularly to a high-efficiency processing device for heterogeneous preforms. Background Technology

[0002] Crucibles, flow guides, and other thermal field structural components are important parts of the hot field components of single crystal furnaces. With the dual-carbon policy in recent years, major photovoltaic and semiconductor companies have been expanding their production capacity and increasing the number of furnaces, resulting in a significant increase in the demand for crucibles.

[0003] Currently, most manufacturers use single-head winding technology to prepare irregularly shaped preforms such as crucibles and guide tubes, employing a combination of mesh and carbon cloth, with the carbon cloth distributed between multiple layers of mesh. This process requires pauses during the intermittent laying of mesh and carbon cloth, causing interruptions. Furthermore, when laying carbon cloth on irregular surfaces, excess material needs to be manually trimmed to ensure proper fit with the mold. The carbon cloth on irregular surfaces is also difficult to secure, leading to shallow needle penetration, wrinkling, and detachment. This requires multiple workers, resulting in a large workload and increased production cycle. In addition, the carbon cloth experiences mechanical wear during weaving, reducing its strength by approximately 20%. Preform fabrication requires the directional winding of carbon wire around the mesh or carbon cloth. Current technologies mostly use manual winding methods. While some manufacturers use automated winding machines, this only automates radial or circumferential winding, and production efficiency remains low. In conventional processing methods, single-head winding of a single 36-inch crucible preform takes at least 18 hours, resulting in a long production cycle. In summary, the existing equipment has the following problems: (1) The equipment has a low degree of automation in winding and cannot complete the multi-angle winding process; (2) The manual work of the irregular surface reinforcement layer is large and the efficiency is low during the processing; (3) It cannot realize the winding of long fibers to replace traditional carbon cloth and reduce the mechanical loss in the carbon cloth weaving process; (4) It cannot realize the function of 1 machine with 4 outputs.

[0060] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the following will be described in conjunction with the accompanying drawings. Figures 1-16 The technical solutions of the embodiments of the present invention are clearly and completely described. Obviously, the described embodiments are only a part of the embodiments of the present invention, not all of them. All other embodiments obtained by those skilled in the art based on the described embodiments of the present invention are within the scope of protection of the present invention.

[0061] like Figures 1-2 As shown, the present invention discloses a high-efficiency processing device for heterogeneous preforms. The processing device 100 includes a main frame 1, a processing table 2, a back-piercing device 3, a rear-side needle-piercing device 4, a side-side needle-piercing device 5, a winding mechanism 6, and a cutting mechanism 8. The main frame 1 includes a support base frame 11, a support back frame 12 located at the rear of the support base frame, and a support top frame 13 located at the top of the support back frame. The support back frame 12 is laterally arranged with multiple back frame crossbeams 121. The number of back frame crossbeams 121 can be one or two, depending on the requirements. The support top frame 13 is laterally arranged with multiple support guide beams in parallel. In a specific embodiment, the number of support guide beams is three, namely a first support guide beam 131 located at the front of the support top frame, a second support guide beam 132 located in the middle of the support top frame, and a third support guide beam 133 located at the rear of the support top frame. The first support guide beam 131, the second support guide beam 132, and the third support guide beam 133 are respectively provided with grooves 134 on both sides along their length direction.

[0062] like Figures 1-2 and Figures 11-12As shown, multiple first guide bars 111 are arranged parallel to each other along the front-back direction on the support base 11. The processing table 2 includes a movable table 21 that is slidably connected along the front and back of the support base 11 and a support shaft frame 22 mounted on the movable table. The movable table 21 includes a support plate 211 that is slidably connected to the first guide bars 111. Multiple transmission screws 112 that are arranged parallel to the first guide bars 111 are rotatably connected on the support base 11. The front end of the transmission screw 112 is connected to the support plate 211, and the rear ends of the multiple transmission screws 112 are linked together through a front and rear drive mechanism 113. The front and rear drive mechanism 113 can be a sprocket drive mechanism or a pulley drive mechanism, and its transmission form can be set according to requirements. Specifically, the transmission lead screw can be a 5010 ball screw, and the front and rear drive mechanism 113, which is equipped with the transmission lead screw, can be composed of a 1.5Kv servo motor and a 1:30RV75 reducer, etc. The bottom surface of the support plate 211 is provided with a lead screw sleeve that is slidably connected to the transmission lead screw, and the bottom surface of the support plate 211 is provided with a groove that engages with the first guide bar 111. The front and rear drive mechanism 113 drives the lead screw sleeve (not shown in the figure) to move forward or backward along the transmission lead screw by driving the transmission lead screw 112 to rotate, thereby realizing the sliding of the moving table 21 along the first guide bar 111.

[0063] Lifting mechanisms 212 are respectively provided at the four corners of the top of the support platform 211, and support side beams 214 are connected across the two sets of lifting mechanisms at both ends of the support platform 211. A guide mechanism 213 is provided on the support platform 211 between the two sets of lifting mechanisms 212 and is fixedly connected to the support side beams 214. The lifting mechanism 212 can use a hydraulic cylinder, a drive cylinder, or a drive electric cylinder in the prior art to achieve its lifting function, and the guide mechanism 213 uses a guide column and a guide sleeve to achieve its guiding function. In an optional embodiment, such as Figure 4 As shown, the lifting mechanism 212 employs a drive electric cylinder, and each lifting mechanism 212 is equipped with a drive motor to achieve the lifting function. In another optional embodiment, as... Figures 13-14 As shown, the lifting mechanism 212 includes four lifting cylinders 2121. The two lifting cylinders 2121 at both ends are connected by a first lifting transmission mechanism 2122 and a second lifting transmission mechanism 2124 respectively. The first lifting transmission mechanism 2122 and the second lifting transmission mechanism 2124 are connected by a transmission rod 2123. A lifting drive motor is provided in cooperation with the first lifting transmission mechanism 2122 and the second lifting transmission mechanism 2124. The lifting drive motor and the lifting transmission mechanism can realize the lifting drive of the supporting side beam 214.

[0064] Multiple support shafts 222 for mounting the processing mold 7 are arranged in parallel on the support shaft bracket 22, and a self-rotating drive mechanism 23 for driving the support shafts 222 to rotate is provided at one end of the support shaft bracket 22. In a specific embodiment, such as Figure 3As shown, the support shaft frame 22 includes support side plates 221 respectively disposed on the support side beam 214. The top of each support side plate 221 has a first slot 2211, which is open and allows the support shaft 222 to be fitted. The front middle of each support side plate 221 has a second slot 2212, which is also open and allows the support shaft 222 to be fitted. The support shaft 222 is fitted into the first slot 2211 and the second slot 2212 respectively. A processing mold 7 is clamped in the middle of the support shaft. The processing mold 7 is for spinning and winding. The moving table 21 can drive the support shaft frame 22 to move stably up and down through the cooperation of the lifting mechanism 212 and the guiding mechanism 213. In this embodiment, the self-rotation drive mechanism 23 includes a power gear 232 on the outside of the support side plate 221 and connected to the end of the support shaft 222. A transmission gear 233 that meshes with the power gear is rotatably connected to the outside of the support side plate 221. A drive gear and a first drive motor 231 that is connected to the drive gear are fitted between the two sets of transmission gears 233. The first drive motor 231 can drive the power gear 232 to rotate by driving the transmission gear 233, thereby driving the support shaft 222 and the processing mold 7 on it to rotate, so as to realize the wire winding operation.

[0065] In another alternative embodiment, such as Figures 13-14 The support shaft frame 22 includes support side plates 221 respectively disposed on the support side beam 214. The two sets of support side plates 221 are rotatably connected to each other vertically. The support shaft 222 includes end shafts 226 respectively rotatably connected to the support side plates 221 and shaft rods 227 detachably connected between the two end shafts through connecting parts 225. The processing mold 7 is clamped on the shaft rods 227. A support arm plate 223 supporting the upper shaft rod 227 is disposed on the inner side of the support side plate 221. Support columns 224 supporting the lower shaft rod 227 are disposed at both ends of the support platform 211. In this embodiment, the self-rotation drive mechanism 23 that cooperates with the two end shafts 226 on one side is a drive pulley mechanism or a drive sprocket mechanism, which will not be described in detail here.

[0066] like Figures 1-3 and Figures 11-14 As shown, the shape of the processing mold can be selected from circular, elliptical, cocoon-shaped and other structures to meet the processing requirements of different preforms; the processing table 2 can realize convenient adjustment of the front and rear position and spatial height of the processing mold 7 on the main frame 1, meet the automatic control of the processing station, and can produce multiple preform products at one time, thereby improving the processing efficiency of the processing device 100.

[0067] like Figure 2 and Figures 5-6As shown, a back-stabbing device 3 is fixedly connected to two back frame crossbeams 121 on the support back frame 12. The back-stabbing device 3 includes two sets of first support lugs 31 disposed on the back frame crossbeams 121 and a first drive crossbeam 35 rotatably connected between the two sets of first support lugs 31. A first drive cam 32 is disposed at each end of the first drive crossbeam 35, and a first drive rod 33 is hinged to the protrusion of the first drive cam 32. A support cantilever 39 extends from one side of the back frame crossbeam 121 to connect to the first drive rod 33. The front end of the drive rod 33 is fixedly connected to a first needle plate 34. Multiple needles are evenly distributed on the surface of the first needle plate 34 to perform hooking and piercing actions on the preform mesh. The first needle plate 34 is relatively long, and its length can be selected according to the shape of the preform. For example, if a cocoon-shaped preform is prepared, with a columnar structure in the middle and spherical structures at both ends, the back piercing device 3 will perform a needle piercing action on the columnar structure, and its length is consistent with the length of the column. If a spherical preform is prepared, the back piercing device 3 will perform a hooking and piercing action on the circumferential part of the middle of the spherical structure. Two first drive crossbars 35 are respectively provided with first drive wheels 36. The two first drive wheels 36 are connected by a first transmission belt 37. A second drive motor 38 is provided in cooperation with the first transmission belt 37. The second drive motor 38 drives the first transmission belt 37 to rotate, which in turn drives the first drive wheels 36 to rotate, thereby driving the first drive cams 32 at both ends of the first drive crossbars 35 to rotate. During the rotation of the first drive cams 32, the first drive rod 33 is driven to reciprocate back and forth, which in turn drives the first needle plate 34 to reciprocate back and forth hooking and piercing. The two sets of back-piercing devices 3 are linked together. Each back-piercing device 3 and its corresponding processing mold 7 perform reciprocating needle-piercing action to realize the hooking and piercing of the prefabricated mesh tire.

[0068] like Figure 1 , Figure 2 and Figure 7As shown, rear-side needle-piercing devices 4 are respectively arranged on both sides of the support frame 12 located on the back-piercing device 3. The rear-side needle-piercing device 4 includes a movable guide beam 9 that slides left and right along the third support guide beam 133 of the support top frame 13. The movable guide beam 9 is arranged perpendicular to the support guide beam, and a second guide groove 91 adapted to the third support guide beam 133 is opened on the movable guide beam 9. A fourth guide strip 92 adapted to the groove 134 is arranged on the inner walls of both sides of the second guide groove 91. A fifth guide strip 9 is arranged on both sides of the lower part of the movable guide beam 9. 3. A needle-punching mechanism 10 is slidably connected to the lower side of the movable guide beam 9 along the fifth guide bar 93. The needle-punching mechanism 10 performs reciprocating needle-punching actions corresponding to the curved surfaces at both ends of the processing mold 7. The position of the rear side needle-punching device 4 on the main frame 1 can be adjusted by moving the movable guide beam 9 left and right along the third support guide beam 133. The relative position of the needle-punching mechanism 10 and the processed curved surfaces at both ends of the processing mold 7 can be adjusted by controlling the needle-punching mechanism 10 to move back and forth along the movable guide beam 9, so as to meet the needle-punching processing of the curved surfaces at both ends of the irregular precast component. Side needle-punching devices 5 are respectively provided at the middle of both ends of the support top frame 13. The side needle-punching device 5 includes a needle-punching mechanism 10 that slides left and right along the second support guide beam 132 of the support top frame 13. The needle-punching mechanism 10 performs reciprocating needle-punching actions corresponding to the two ends of the processing mold 7. With the cooperation of the rear side needle-punching device 4 and the side needle-punching device 5, the irregular surfaces at both ends of the precast components with different shapes and structures can be hooked and punched.

[0069] Both the rear-side needle-punching device 4 and the side needle-punching device 5 include a needle-punching mechanism 10, and the structure of the needle-punching mechanism 10 is the same. The difference lies in the direction in which the needle-punching plate in the needle-punching mechanism 10 faces the processing mold 7. Specifically, as shown... Figure 8 and Figure 15As shown, the needle-punching mechanism 10 includes a movable slider 107 adapted to the second support guide beam 132 or the movable guide beam 9, and a mounting longitudinal plate 101 fixedly connected to the movable slider 107. Two sets of support horizontal plates 102 are arranged vertically and vertically on one side of the mounting longitudinal plate 101. Needle-punching units 104 are rotatably connected to the support horizontal plates 102 respectively. The needle-punching unit 104 includes a support turntable 1041 arranged on the support horizontal plate 102. Two sets of bearing seats are arranged on the rear side of the support turntable 1041, and a second drive crossbar 1045 is rotatably connected in the bearing seats. A second drive cam 1044 is fixedly fitted at one end of the second drive crossbar 1045, and a second drive rod 1043 is hinged to the protrusion of the second drive cam 1044. A second support lug 1042 for the second drive rod 1043 to be connected is arranged at the front end of the support turntable 1041, and a second needle-punching plate 1046 is fixedly connected to the front end of the second drive rod 1043. Two sets of needle-punching units 104, arranged vertically and vertically, are connected by a linkage drive assembly 106. The linkage drive assembly 106 includes a second drive wheel 1061 fixedly connected to one end of the second drive crossbar 1045 and a seventh drive motor 1063. The shaft end of the seventh drive motor 1063 is provided with a drive pulley 1064. The drive pulley 1064 is connected to the second drive wheel 1061 by a third transmission belt 1062. The seventh drive motor 1063 drives the drive pulley 1064 to rotate and drives the second drive wheel 1061 to rotate through the third transmission belt 1062. This drives the second drive crossbar 1045 to drive the second drive cam 1044 to rotate. The rotation of the second drive cam 1044 can push the second drive rod 1043 to reciprocate back and forth, thereby driving the second needle-punching plate 1046 to reciprocate needle-punching action. A rotary drive mechanism 105 is also provided between the two sets of needle-punching units 104. The rotary drive mechanism 105 includes a rotating shaft 1051 fixedly connected to the two supporting turntables and a drive gear 1052 mounted on the rotating shaft. A sixth drive motor 1053 is provided in cooperation with the drive gear 1052. The shaft end of the sixth drive motor is provided with a power gear that fits with the drive gear 1052. The sixth drive motor 1053 drives the rotating shaft 1051 to rotate, thereby causing the needle-punching unit 104 to rotate along the supporting horizontal plate 102. That is, the rotary drive mechanism 105 synchronously drives the needle-punching unit 104 to rotate along the supporting horizontal plate 102, thereby adjusting the working surface of the needle-punching unit 104 during the needle-punching process.

[0070] The structure of the movable slider 107 is the same as the working principle of the movable guide beam 9. In an optional embodiment, such as Figure 7 and Figure 16 As shown, both the movable slider 107 and the movable guide beam 9 can employ linear slide rail technology to achieve linear sliding functionality. In another optional embodiment, such as Figures 11-12 and Figure 15As shown, the rear-side needle-piercing device 4 and the side-side needle-piercing device 5 can be moved by a hydraulic drive mechanism 20. The hydraulic drive mechanism 20 includes a hydraulic oil station 201 located on one side of the main frame 1 and multiple hydraulic cylinders connected to the hydraulic oil station. A first hydraulic cylinder 202 connects the two sets of moving guide beams 9, and driving the first hydraulic cylinder 202 adjusts the distance between the two sets of rear-side needle-piercing devices 4. The moving slider 107 of the rear-side needle-piercing device 4 is connected to the moving guide beam 9 via a second hydraulic cylinder 203, which drives the moving slider 107 and its lower needle-piercing mechanism 10 to move forward or backward along the moving guide beam 9. The moving sliders 107 of the two sets of side-side needle-piercing devices 5 are connected via a third hydraulic cylinder 204, which also adjusts the distance between the two sets of side-side needle-piercing devices 5.

[0071] The processing device of the present invention uses a back-piercing device 3, two sets of rear-side needle-piercing devices 4 and two sets of side needle-piercing devices 5 to perform hook-piercing actions on the mesh layer and winding layer of the irregular preform. The needle-piercing speed is adjusted by the frequency of the corresponding drive motor to meet the processing requirements of preforms of various shapes.

[0072] like Figures 9-10As shown, a winding mechanism 6 is slidably connected to the first support guide beam 131 of the support top frame 13. The winding mechanism 6 includes a first guide slider 61, which is an L-shaped slider. The lower side of the crossbeam of the L-shaped slider is provided with a first guide groove 611 corresponding to the support guide beam. A third guide strip 612 is provided along the inner walls of both sides of the first guide groove 611. The first support guide beam 131 has grooves 134 on both sides for the fourth guide strip to be installed. A third drive motor 65 is provided in cooperation with the first guide slider 61. The third drive motor 65 can drive the first guide slider 61 to slide stably left and right along the first support guide beam 131. A spinning frame 62 is fixedly installed on the front side of the first guide slider 61. Multiple yarn rollers 621 for spinning and winding are installed in the mounting groove of the spinning frame 62, and a guide nozzle 622 is provided at the lower end of the spinning frame 62. Different types of yarn can be wound onto the yarn rollers 621 for later use. A housing 63 is detachably fitted on the outside of the spinning frame 62. A winding mechanism 64 is rotatably connected to the front side of the housing 63. The winding mechanism 64 includes two sets of adjusting seats 643 rotatably connected to the upper and lower parts of the housing 63, respectively, and the adjusting seats 643 communicate with the inner cavity of the housing 63. The spinning yarn wound on the 21 passes through the guide nozzle 622 and wraps around the adjusting seat 643 to wind onto the processing mold 7. Two sets of adjusting seats 643 are connected by a second transmission belt 642, and an angle adjusting motor 641 is set in cooperation with the second transmission belt 642. The angle adjusting motor 641 drives the second transmission belt 642 to drive the adjusting seat 643 to rotate, thereby adjusting the winding direction of the spinning yarn to meet the processing requirements of different prefabricated structures. The winding mechanism 6 continuously supplies yarn to the processing mold 7, and the type of yarn can be freely selected according to the requirements. Specifically, the winding angle is adjusted by controlling the moving speed of the winding mechanism 6 along the first support guide beam 131 and the rotation speed of the support shaft 222. In addition, the winding mechanism 64 can increase the winding angle adjustment range to 15~75°, so that different winding layers form an inclined cross-shaped fishing net structure, thereby improving the structural strength of the prefabricated body, eliminating the need for carbon cloth to reinforce the mesh layer structure, shortening the processing steps, and improving the processing efficiency of the prefabricated body.

[0073] In an alternative embodiment, such as Figure 4 As shown, a third guide bar 216 is arranged along the transverse direction on the front side of the support plate 211, and the cutting mechanism 8 is slidably connected to the support plate 211 along the third guide bar 216. The cutting mechanism 8 includes a movable pile, and a fifth drive motor is arranged at the top of the movable pile. The fifth drive motor can drive the movable pile to move left and right along the third guide bar 216. A cutting tool is arranged on the inner side of the top of the movable pile. The cutting tool can rotate along the movable pile. The cutting tool can be adjusted to a horizontal or vertical state, so that it can perform cutting action along the axial or radial direction of the processing mold 7 to meet the cutting and forming of the preform product.

[0074] In the above embodiments, a flange design is adopted along the vertical plane in the center of the processing mold 7, which can divide the crucible processing mold into two symmetrical groups. A single processing mold 7 can produce two bowl-shaped crucibles at one time. The processing device 100 is equipped with two processing molds 7, which can form four bowl-shaped crucibles at one time, thereby improving the production efficiency of the preform product and reducing the production cost. The winding mechanism 6 can circumferentially wind and spin yarn along the spherical processing mold 7 to form an annular winding layer. When the annular winding layer reaches a certain thickness, the mesh layer is laid. The mesh layer and the annular winding layer are needled and connected by the back-punching device 3, two sets of rear side needle-punching devices 4, and two sets of side needle-punching devices 5. Then, the winding angle is adjusted to wind and spin yarn outside the mesh layer to form an angled winding layer. After reaching a certain thickness, the mesh layer is laid. The mesh layer and the angled winding layer are needled by the back-punching device 3, two sets of rear side needle-punching devices 4, and two sets of side needle-punching devices 5. The above actions are repeated until the product thickness reaches the requirement.

[0075] In the above embodiments, each drive motor in the processing device 100 can be a servo motor or a stepper motor, and each linear sliding component can be a linear slide rail in the prior art to realize the sliding drive function; the processing table 2, the rear side needle punching device 4, the side needle punching device 5, the winding mechanism 6, and the cutting mechanism 8 can all be moved to the corresponding processing station through the linear sliding components. The linear sliding components in this embodiment, such as the moving guide beam 9 and the third support guide beam 133, and the first guide slider 61 and the first support guide beam 131, have the same working principle, which will not be described in detail here.

[0076] The working principle or method of this invention:

[0077] The processing device 100 of the present invention can control each drive motor to cooperate in various actions of preform preparation, such as winding the preform mesh, needle punching, cutting and other actions, through a PLC control cabinet (not shown in the figure).

[0078] (1) Fix the two processing molds 7 on the support shaft 222 respectively to complete the clamping and fixing of the processing molds 7; the front and rear drive mechanism 113 drives the processing table 2 to move along the first guide bar 111 on the support base frame 11 to the inside of the main frame 1 through the transmission screw 112, and then moves the processing table 2 to below the first support guide beam 131 and the second support guide beam 132; control the lifting mechanism 212 and the guide mechanism 213 to drive the support shaft frame 22 to rise to a suitable position below the winding mechanism 6. During the processing, drive the support plate 211 to move forward or backward along the support base frame 11 to adjust the processing position. The self-rotation drive mechanism 23 drives the processing mold 7 to rotate and cooperate with the winding mechanism 6 to perform spinning and winding actions.

[0079] (2) The winding mechanism 6 slides back and forth along the first support guide beam 131 via the first guide slider 61, and in conjunction with the rotating processing mold 7, the processing mold 7 can form a circumferential winding layer by circumferential winding and spinning, thus completing the binding of the mesh layer.

[0080] (3) After the thickness of the winding layer on the processing mold 7 reaches a certain size, control the two sets of side needle punching devices 5 to move left and right along the second support guide beam 132 to a suitable processing position, and control the two sets of rear side needle punching devices 4 to move left and right along the third support guide beam 133 to a suitable processing position; when the needle punching mechanism 10 reaches the needle punching position, the support turntable 1041 is rotated and the processing position is adjusted by controlling the sixth drive motor; at the same time, the second drive motor 38 and the seventh drive motor 1063 are started to needle punch and reinforce the mesh layer and the circumferential winding layer on the processing mold.

[0081] (4) Then, the rotation angle of the adjusting seat 643 is adjusted by the adjusting motor 641 to adjust the winding angle of the spinning on the processing mold 7. The spinning is wrapped around the outer layer of the mesh to form an angle winding layer. After reaching a certain thickness, the mesh layer is laid. The mesh layer and the angle winding layer are needled and hooked together by the back needle device 3, two sets of rear side needle punching devices 4 and two sets of side needle punching devices 5.

[0082] (5) Repeat the above-mentioned processes of laying the mesh, multi-angle winding and spinning, and needle punching until the thickness of the precast body reaches the required level and the precast body processing is completed; then, control the moving pile to move along the third guide bar 216 and complete the cutting and shaping of the precast body by cutting tool.

[0083] The above are preferred embodiments of the present invention. It should be noted that, for those skilled in the art, several improvements and modifications can be made without departing from the principle of the present invention, and these improvements and modifications should also be considered within the scope of protection of the present invention.
