Description

Technical Field

[0001] The invention belongs to the technical field of silver mirror production and preparation, and in particular relates to a SMC lining plate processing feeding system. Background Art

[0002] At present, the reflector glass used in our solar thermal power generation field is about 4mm, and the ceramic sheet with bolts is attached to the glass to connect with the bracket. The strength of this structure depends entirely on the quality of the glass, so the life of the solar thermal power generation reflector part will be affected. In addition, the reflectivity of this reflector is only about 93%, which affects the efficiency of solar thermal power generation.

[0003] The applicant proposed a process of using SMC material hot pressing molding as a reflector back plate. SMC composite material is a kind of glass fiber reinforced plastic.

However, during the molding process, the sheet material needs to be fed into the molding equipment. The sheet material is relatively thin and is in the form of a coil. How to safely and efficiently achieve its feeding has become an urgent problem to be solved. Moreover, during molding, the positioning on the bracket is generally achieved by pre-embedded nuts. However, the placement of existing nuts mostly relies on manual placement, which leads to low efficiency and safety hazards. Summary of the invention

[0029] In order to enable those skilled in the art to better understand the technical solution of the present invention, the technical solution of the present invention is further described below in conjunction with specific embodiments.

[0030] Embodiment 1

[0031] A feeding system for processing SMC liner, including an SMC raw material supply device and a nut supply device; the SMC raw material supply device includes a track 11 horizontally arranged on a frame 1, an SMC carrier plate 10 matchedly arranged on the track, a feeder rack 20 arranged on the frame and driven to move longitudinally, the feeder rack is located above the right end of the track, the feeder rack includes a top drive arm 21, a carrier plate 22 arranged below the top drive arm and driven to move up and down, and a clamping mechanism arranged on the carrier plate for clamping the SMC raw material, the clamping mechanism includes shovel plates 23 at the front and rear ends and side clamping mechanisms 24 located on the left and right sides. In the present invention, the horizontal direction is the left and right direction, and the longitudinal direction is the front and back direction for exemplary description. The nut supply device includes multiple groups of supply mechanisms, each group of supply mechanisms includes a nut carrier plate 41, a discharge mechanism 42 and a vacuum suction part 43, the nut carrier plate includes a nut carrier plate 411 that is inclined and driven to step along the front and rear directions, and an exciter 412, the nut carrier plate is provided with multiple T-slots 414 that can match the bottom ring of the nut, the discharge mechanism includes a guide groove 421 that matches the T-slot, and a sliding table 422 arranged at the other end of the guide groove, the sliding table is formed with an embedding groove 423 that can accommodate the nut on the adjacent side of the guide groove, and the sliding table is driven to move back and forth in the front and rear directions to switch between the feeding position and the taking position.

[0032] Specifically, the material guide trough is an S-shaped trough or an arc track to reduce material jamming, and the sliding table is arranged on the frame through a guide rail slider and is driven and switched by a sliding cylinder.

[0033] The SMC liner processing feeding system of the present invention realizes the transportation of SMC raw materials by combining the left and right movement of the SMC carrier plate and the front and back movement of the feed rack, and realizes the material transfer by utilizing the lifting of the carrier plate, wherein the carrier plate is realized by the vertically arranged carrier plate cylinder to realize the said up and down movement. Moreover, when dealing with relatively soft SMC raw materials, a combination of the two methods of lifting by the shovel plate bottom support at the front and rear ends and the clamping and positioning on both sides is adopted to ensure an effective clamp, prevent the material from falling off, and improve production efficiency. The present invention adopts a clip-type feeding device, utilizes the high capacity of the nut carrier plate, utilizes an exciter to realize vibration downward feeding, cooperates with the guide trough and the sliding table, realizes stable feeding one by one, ensures the stability of automation, grabs the nut through the vacuum suction part, reduces the high space occupation problem of the claws, etc., realizes the action in a small space, and has good controllability.

[0034] Preferably, the frame includes at least two columns fixedly connected to the ground, one of which is rotatably connected to the ground, and the other column is detachably fixedly connected by bolts, that is, a rotating shaft is arranged between one of the columns and the ground, and a lifting ring is arranged on the top of the frame. After removing the bolts, the frame is lifted as a whole by a lifting device and rotated about the rotating shaft. In this way, when a mold fails, it can be removed without disassembling the frame and its auxiliary structures, which is convenient for subsequent maintenance of the mold.

[0035] The vacuum suction part 43 includes a vacuum generator, a nut suction chamber 431 connected to the vacuum generator and matching with the top round table embedded therein, and a suction cylinder 432 driving the nut suction chamber to move up and down. The vacuum generator starts to work after the top round table of the nut is embedded in the nut suction chamber to achieve adsorption.

[0036] Among them, according to design requirements, any number of supply mechanisms can be included, such as six groups of supply mechanisms. The vacuum suction parts of each group of supply mechanisms are fixedly connected to the feeding rack, and the remaining components can be set accordingly. The assembly is convenient and simple to implement.

[0037] Specifically, the shovel plate 23 is used to be inserted between the SMC carrier plate and the SMC raw material, that is, inserted under the SMC raw material and lift it. The middle of the front and rear ends of the SMC carrier plate is provided with a slot opening 12 corresponding to the shovel plate on the upper surface. The shovel plate is driven to clamp or release the SMC raw material in the front and rear directions. Preferably, a shovel plate cylinder 231 is provided on the carrier plate, and the shovel plate 23 is connected to the shovel plate cylinder through a transmission plate 232. The piston rod of the shovel plate cylinder extends in the front and rear directions and is connected to the shovel plate through a vertically arranged transmission plate. The shovel plate is located under the carrier plate so as to be inserted under the SMC.

[0038] Preferably, the shovel plate is made of plastic and has a guide slope formed on the inner end to facilitate smooth insertion into the slot. Moreover, pads 15 are provided on both sides of the slot on the upper surface of the SMC carrier plate. The pads can effectively ensure that the SMC is kept away from the bottom surface of the slot to maintain a gap for the shovel plate to be inserted. The bottom surface of the slot is an inclined surface that gradually reduces the depth of the slot so that the insert plate can support the SMC raw material during the insertion process.

[0039] The nut 3 suitable for SMC liner includes a cylindrical body 31 formed with a threaded inner cavity, a bottom ring 32 integrally formed on the bottom open end side of the body, a middle ring 33 integrally formed in the middle of the outer side of the body and spaced apart from and parallel to the bottom ring, and a top ring 34 integrally formed on the top of the outer side of the body.

[0040] Preferably, the middle ring and the top ring are polygonal, and the radius of the circumscribed circle of the polygon is the same as the radius of the bottom ring.

[0041] The nut can be injection molded in one step using materials such as aluminum alloy, and the three ring edges on the outer side of the main body are arranged to increase the stability of the connection with the SMC liner. Moreover, the design of the bottom ring increases the bottom surface area, which can prevent the material from clogging the threaded hole during injection molding. At the same time, the equal outer circle design facilitates subsequent placement in the mold hole, thereby achieving precise positioning.

[0042] Furthermore, a top truncated cone 35 is formed integrally on the top of the top ring, and the radius of the top truncated cone is greater than the radius of the body and is coaxially arranged. The top truncated cone design provides a point of action for subsequent vacuum adsorption, realizing the automation of supply.

[0043] Embodiment 2

[0044] Further, the side clamping mechanism includes an L-shaped transmission plate 241 which is arranged corresponding to the SMC carrier plate and driven to flip inward, and a plurality of bottom clamping blocks 242 are arranged on the transmission plate to hold the side of the carrier plate to clamp the SMC raw material. At the same time, a top clamping block 222 is arranged on the carrier plate 22 to cooperate with the bottom clamping block to clamp, and at the same time, a notch 13 corresponding to the bottom clamping block is arranged on the SMC carrier plate. Specifically, the L-shaped transmission plate is driven by a rotary cylinder 244 at the front and rear ends.

[0045] The side clamping mechanism adopts a rotating clamping method, which can ensure entry from the bottom of the SMC raw material, and multi-point clamping positioning can meet the clamping requirements of soft materials. At the same time, the L-shaped transmission plate not only realizes the transmission purpose, but also supports the material in the material lifting mode to prevent excessive descent and separation from the clamping point.

[0046] Embodiment 3

[0047] Specifically, because the SMC raw material is a coil, it must be cut to a fixed length in the early stage, and then folded and placed on the SMC carrier plate. In order to avoid product quality problems caused by inconsistent feeding amount, the track includes a weighing section 111 located at the left end and a conveying section 112 located on the right side of the weighing section. A weight sensor is arranged between the track and the base frame of the weighing section. The two sections of the track are arranged so that the loading positions are relatively independent, so that loading and weighing can be carried out simultaneously, and the only reasonable gap does not affect the movement of the SMC carrier plate on the track. For example, a roller groove is formed on the track, and a roller is arranged at the bottom of the SMC carrier plate and is driven by a synchronous belt to move along the track.

[0048] Furthermore, the SMC carrier plate is provided with a plurality of weight-reducing holes, and L-shaped corner blocks 14 are provided at the four corners of the SMC carrier plate to achieve the initial positioning of the SMC raw materials. The design of the weight-reducing holes reduces the dead weight and improves the operating efficiency, and the initial positioning ensures the subsequent clamping and the accuracy of weighing.

[0049] Embodiment 4

[0050] In order to achieve the optimal setting of the nut carrier plate, the nut carrier plate also includes a nut carrier plate base plate 413 which is tilted and driven to step along the front-to-back direction. The nut carrier is detachably fixed on the nut carrier plate base plate and positioned by magnets and pins. The vibrator 412 is arranged on the nut carrier plate base plate. The detachable setting of the nut carrier is convenient for replacement and material loading.

[0051] Wherein, a plurality of strip-shaped bosses arranged at intervals are formed on the upper surface of the nut carrier plate, and a strip plate having a width greater than that of the boss is fixedly arranged on the boss to form the T-shaped groove.

[0052] Furthermore, to facilitate the movement of the nut carrier, a handle 415 is fixedly provided on the nut carrier, and a liftable baffle 416 corresponding to the discharge end of the T-slot is provided on the handle, and a stopper is provided at the other end of the T-slot; that is, the discharge port of the nut is the loading port, and the lifting baffle can be used to limit it in the T-slot after loading is completed. After being fixed on the nut carrier plate base plate, the liftable baffle can be lifted. At the same time, the T-slot is blocked by the end stop 417 directly fixed to the frame. The end stop 417 is arranged on one side of the material guide slot and corresponds to the material storage area. When the nut carrier plate base plate moves, the T-slot closest to the material guide slot can be freed from the constraint of the liftable baffle, and the nut in the T-slot can enter the material guide slot in sequence.

[0053] Embodiment 5

[0054] The control method of the supply device of the present invention comprises the following steps:

[0055] 1) The vibrator vibrates, and the nut in the T-slot corresponding to the material guide slot is vibrated into the material guide slot, and the nut at the front of the material guide slot enters the insert slot;

[0056] 2) After the nut in the insert groove is detected to be in place, the vibrator stops vibrating and the sliding table is driven to slide to the feeding position;

[0057] 3) The nut suction chamber falls and the vacuum generator is activated to achieve nut suction.

[0058] 4) The feeding rack moves the nut to the specified position, the vacuum generator stops working, and the nut is released.

[0059] The control method of the present invention has a simple rhythm and can provide feedback through sensors in each link, thereby ensuring the smooth progress of the entire process, ensuring the stability of product quality, and operating fully automatically, reducing manual participation, improving efficiency, and ensuring personal safety.

[0060] The control method of the SMC raw material supply device comprises the following steps

[0061] 1) The weight sensor senses the weight of the SMC raw material on the SMC carrier plate. If it meets the requirements, it will proceed to the next step, otherwise it will alarm.

[0062] 2) The SMC carrier plate is driven to move to the right end, and the carrier plate is driven to fall;

[0063] 3) The side clamping mechanism and shovel plates on both sides clamp the SMC raw materials, and then the carrier plate is driven to rise, and the SMC carrier plate is reset;

[0064] 4) After the feed rack delivers the SMC raw material to the predetermined position, the carrier plate falls and releases the SMC raw material.

[0065] By adopting the above control logic, synchronous weight detection can be achieved during loading, effectively ensuring the quality of subsequent processing. At the same time, the effective combination of lateral movement and longitudinal movement can reduce the footprint of the equipment and improve the overall efficiency. The feeding rack can be used to directly transport the materials into the mold, reducing the risk of manual operation.

[0066] For ease of explanation, spatial relative terms such as "upper", "lower", "left", "right" and the like are used in the embodiments to illustrate the relationship of one element or feature shown in the figure relative to another element or feature. It should be understood that, in addition to the orientation shown in the figure, the spatial terms are intended to include different orientations of the device in use or operation. For example, if the device in the figure is inverted, the element described as being "under" other elements or features will be positioned "on" other elements or features. Therefore, the exemplary term "under" can include both upper and lower orientations. The device can be positioned in other ways (rotated 90 degrees or in other orientations), and the spatial relative descriptions used here can be interpreted accordingly.

[0067] Furthermore, relational terms such as “first” and “second” and the like are merely used to distinguish one component from another having the same name, but do not necessarily require or imply any such actual relationship or order between these components.

[0068] The present invention is described above by way of example. It should be noted that, without departing from the core of the present invention, any simple deformation, modification or other equivalent replacement that can be made by those skilled in the art without inventive effort falls within the protection scope of the present invention.
