Description

Technical Field

[0001] The utility model relates to the technical field of mobile phone cover glass processing, in particular to an automatic feeding structure of a flat oil removal machine for removing an ink protection layer on a mobile phone cover glass. Background Art

[0002] During the processing of mobile phone cover glass, it is often necessary to coat a protective ink on the glass surface to prevent the glass from being scratched during operations such as profiling edging, polishing, and CNC machining, so as to reduce the defective rate of products. After the above processing of the mobile phone cover glass is completed, it is also necessary to remove the protective ink on the glass surface to keep the glass surface clean. Currently, in the industry, products in a tray are mainly grabbed by a suction cup or a suction pen, and driven by a servo module, the products to be removed of the protective oil are transferred to the feeding section of a flat oil removal and cleaning machine to achieve automatic feeding of the products to be removed of the oil. Before loading onto the machine, it is necessary for workers to sort and place the products in the tray, and then place the products manually at the feeding position of the machine table tray. The tray is conveyed in a divided manner by the belt to the grabbing module. The control system adjusts the X / Y-axis servo module according to the size of the tray and positions the products in the tray, and then the suction cup sucks the products in the tray and transfers them to the feeding section of the flat oil removal and cleaning machine, thus completing the feeding action. When all the products in the tray are sucked, the empty tray is conveyed by the belt to the tray discharging position to complete the discharging and recycling of the empty tray.

[0003] For the above feeding equipment of the flat oil removal and cleaning machine, since a suction cup or a suction pen is used to grab the products, it is necessary to use a servo motor or a cylinder to drive for vertically picking up and placing the products, and its overall structure is complex, and the production cost of the equipment is high. When the vacuum of the suction cup or the suction pen is abnormal, it is easy to cause the products to fall during picking up and placing, resulting in defects such as chipping and scratching of the products; and as the use time prolongs, the suction pen is prone to aging, its elasticity decreases, and it needs to be replaced regularly, increasing the use cost of the equipment. In addition, since the feeding products of the flat oil removal and cleaning machine are products after grinding and polishing, they are usually stacked in multiple pieces, and since protective ink is printed on both sides of the glass, the products after grinding processing have residual liquid such as grinding powder water, and the adsorption between products is strong, and the separation is difficult. It is necessary to configure workers to separate the products to be removed of the protective ink and then place them in the tray, resulting in insufficient feeding efficiency and production efficiency of the products.

[0028] In order to make the above objects, features and advantages of the present utility model more obvious and understandable, the following detailed description of the specific embodiments of the present utility model will be given with reference to the accompanying drawings. Many specific details are set forth in the following description in order to fully understand the present utility model. However, the present utility model can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without departing from the connotation of the present utility model. Therefore, the present utility model is not limited by the specific embodiments disclosed below.

[0029] Please refer to Figure 1-6, the present utility model discloses an automatic feeding structure 10 of a flat oil removal machine with simple structure, low production cost and use cost, no need for manual slicing, and high feeding efficiency and production efficiency. The automatic feeding structure includes a driving mechanism 100, a pushing mechanism 200, a cover plate 300 and a product placement rack 400. The driving mechanism 100 includes a mounting rack 110 arranged on the feeding side of the flat oil removal machine, a telescopic driving member 120 fixed on the mounting rack 110 and a guide rail 130. The guide rail 130 extends along the telescopic direction of the telescopic driving member 120. The pushing mechanism 200 includes a sliding bracket 210 located above the guide rail 130 and a plurality of pushing blocks 220 arranged at intervals and mounted on the sliding bracket 210. The bottom of the sliding bracket 210 is slidably matched with the guide rail 130, and the telescopic end of the telescopic driving member 120 is fixedly connected with the sliding bracket 210. Thus, when the telescopic driving member 120 acts, the telescopic end of the telescopic driving member 120 will push the sliding bracket 210, so that the sliding bracket 210 and the pushing blocks 220 move synchronously along the length direction of the guide rail 130 to adjust the positions of the pushing blocks 220. The cover plate 300 is located above the sliding bracket 210 and fixedly connected with the mounting rack 110. A plurality of through holes 310 are formed in the cover plate 300. The length direction of the through holes 310 is the same as the length direction of the guide rail 130. The plurality of pushing blocks 220 are respectively inserted into the through holes 310 one by one, and the top of the pushing block 220 extends out from the top opening of the through hole 310. The product placement rack 400 is fixed on the upper surface of the cover plate 300 and includes an annular enclosing plate and a plurality of partition plates 410. A cavity is formed inside the annular enclosing plate; the plurality of partition plates 410 are arranged in parallel at intervals in the cavity and fixedly connected with the inner surface of the annular enclosing plate respectively to divide the cavity into a plurality of spaced loading areas 420. The width of the loading area 420 is greater than the width of the through hole 310. An outlet 430 corresponding to the feeding section 20 of the flat oil removal machine is formed on one side of the loading area 420 away from the pushing block 220. In this embodiment, on the one hand, the cover plate 300 is used to support the product placement rack 400 to carry the stacked products to be degreased and cleaned. On the other hand, the through holes 310 on the cover plate 300 are also used to define the sliding paths of the pushing blocks 220 and the products, so that the products can be aligned with the outlet 430 and pushed from the outlet 430 to the feeding section of the flat oil removal machine to ensure the reliability of feeding. It should be noted that in this embodiment, the height of the outlet 430 is greater than the thickness of a single product and less than the sum of the thicknesses of two products, so as to ensure that only one product is pushed out from the outlet 430 each time.

[0030] During the feeding process of the automatic feeding structure, when the telescopic end of the telescopic driving member 120 extends and pushes the sliding bracket 210 to move along the length direction of the guide rail 130, the pushing block 220 pushes the product at the bottommost end in the loading area 420 to slide, so that the product moves to the feeding section 20 of the flat oil draining machine through the discharging port 430. That is to say, in this solution, after the product at the bottommost end in the loading area 420 is pushed out by the pushing block 220, the product originally attached to this product in the loading area 420 descends under its own gravity until it fits against the upper surface of the cover plate 300 and becomes the new bottommost product in the loading area 420, so that the pushing block 220 periodically pushes the products in the loading area 420 until all the products in the loading area 420 are pushed out of the loading area 420. While feeding the products, automatic sheet splitting is realized to improve the feeding efficiency and operation efficiency.

[0031] It should be noted that in this embodiment, the driving mechanism 100 is arranged at the same height as the feeding belt of the flat oil draining machine (also known as the flat oil draining and cleaning machine), so that the glass sheet output by the automatic feeding structure can be accurately sent to the feeding section (i.e., the feeding belt) of the flat oil draining machine. In one embodiment, the automatic feeding structure 10 of the flat oil draining machine further includes a base 500 fixed to the bottom of the mounting frame 110. The base 500 is placed on the ground and used to support the mounting frame 110 and the rest of the components, so as to lift the height of the entire automatic feeding structure, so that the automatic feeding structure and the feeding belt of the flat oil draining machine are at the same height. In addition, the base 500 can also be a bracket with adjustable height, so that the height of the automatic feeding structure can be adapted to the height of the feeding belt of the flat oil draining machine. In another embodiment, the automatic feeding structure 10 of the flat oil draining machine further includes a cantilever fixedly connected to the mounting frame 110 and used to connect to the external frame. The cantilever is used to support the mounting frame 110 and the rest of the components, so as to realize the suspension setting of the automatic feeding structure. In other embodiments, the base 500 or the cantilever can also form a part of the mounting frame 110, which will not be elaborated here.

[0032] In one embodiment, the mounting bracket 110 includes a bottom plate 111 and an annular baffle 112 extending along the edge of the bottom plate 111 and fixedly connected to the bottom plate 111. The guide rail 130 is fixed on the bottom plate 111. The telescopic driving member 120 is mounted on the bottom plate 111 or the inner side surface of the annular baffle 112. The cover plate 300 is erected on the top of the annular baffle 112 and fixedly connected to the annular baffle 112. Preferably, in this embodiment, the bottom plate 111 has a rectangular structure, and the annular baffle 112 has a quadrilateral ring structure. In other words, the mounting bracket 110 has a hollow cuboid structure with an open top. Of course, the bottom plate 111 can also be designed as a pentagonal, hexagonal or circular plate member, and the annular baffle 112 is arranged along the edge of the bottom plate 111. In one embodiment, a plurality of guide rails 130 are arranged on the bottom plate 111 at intervals and in parallel to increase the sliding fit area between the sliding bracket 210 and the bottom plate 111, thereby improving the sliding stability of the sliding bracket 210 and the push block 220. Preferably, in this embodiment, the telescopic driving member 120 is mounted on the inner side surface of the annular baffle 112, and the distance between the telescopic driving member 120 and the upper surface of the bottom plate 111 is greater than 0, so that the driving end of the telescopic driving member 120 is aligned with the sliding bracket 210 and fixedly connected to the sliding bracket 210. In addition, in one embodiment, the telescopic driving member 120 is a cylinder or an electric cylinder. Preferably, the telescopic driving member 120 is a cylinder. The telescopic driving member 120 includes a cylinder body, a piston received in the cylinder body and sealingly fitted with the inner wall of the cylinder body, a piston rod inserted into the cylinder body and fixedly connected to the piston, and a movable plate located outside the cylinder body and fixedly connected to the piston rod and the sliding bracket 210. The cylinder body is communicated with an external air pressure device through an air inlet pipe interface, and the cylinder body is communicated with the environment through an exhaust pipe interface. A first solenoid valve for controlling the on-off of the air inlet pipe interface is provided at the air inlet pipe interface, and a second solenoid valve for controlling the on-off of the exhaust pipe interface is provided at the exhaust pipe interface. By controlling the first solenoid valve and the second solenoid valve to be alternately turned on and off, compressed gas can be introduced into the cylinder body, or the compressed gas in the cylinder body can be discharged, so as to control the movement of the piston, the piston rod, the movable plate and the sliding bracket 210 through the air pressure in the cylinder body.

[0033] The sliding bracket 210 includes a U-shaped frame and a lifting plate 211. The U-shaped frame includes a cross plate 212 and two vertical plates 213 that are oppositely arranged at both ends of the cross plate 212 and are respectively perpendicular to and connected to the cross plate 212. A slider 214 or a chute that is slidably matched with the guide rail 130 is provided at the bottom of the cross plate 212; the lifting plate 211 is located between the two vertical plates 213 and is slidably matched with the two vertical plates 213. The push block 220 is fixed on the upper surface of the lifting plate 211, and a lifting driving member 230 for driving the lifting plate 211 and the push block 220 to lift relative to the cross plate 212 is further installed on the cross plate 212. Further preferably, sliding rails 215 are provided on the inner side surfaces of the two vertical plates 213, and both sides of the lifting plate 211 are respectively and limit-matched with the sliding rails 215 through guide blocks 216 to define the lifting path of the lifting plate 211. In this embodiment, a slider 214 that is slidably matched with the guide rail 130 is provided at the bottom of the cross plate 212. In this embodiment, by providing the lifting driving member 230, the position of the push block 220 in the vertical direction can be adjusted. In other words, the height of the top of the push block 220 protruding from the top opening of the through hole 310 can be adjusted to ensure the contact area between the push block 220 and the product and improve the pushing effect of the push block 220 on the product. Preferably, in this embodiment, the height of the top of the push block 220 protruding from the top opening of the through hole 310 is greater than or equal to half of the thickness of the product, and the height of the top of the push block 220 protruding from the top opening of the through hole 310 is less than the thickness of the product, ensuring that the push block 220 can only push out one glass product at a time, thereby realizing the slicing of the product.

[0034] In this embodiment, a linear bearing 217 is fixed on the upper surface of the cross plate 212, and a positioning shaft 218 inserted into the linear bearing 217 is fixed on the lower surface of the lifting plate 211. Through the limiting cooperation between the linear bearing 217 and the positioning shaft 218, the stability of the lifting of the lifting plate 211 is further improved to avoid shaking during the lifting of the lifting plate 211. In one embodiment, the lifting driving member 230 is a bolt. A threaded hole is formed in the cross plate 212, and a circular groove is formed in the lower surface of the lifting plate 211. The bolt passes through the threaded hole and is in threaded cooperation with the inner surface of the threaded hole. The top of the bolt is rotatably inserted into the circular groove through a pin installed on the lifting plate 211, realizing the limiting of the bolt while ensuring its rotation. Thus, by rotating the bolt, the height of the top of the bolt extending out of the cross plate 212 can be adjusted, and further the height of the lifting plate 211 and the pushing block 220 can be adjusted. In another embodiment, the lifting driving member 230 includes a dial indicator and an inclined block 231. The dial indicator includes a positioning block 232 fixed on the cross plate 212, a screw rod 233 passing through the positioning block 232 and rotatably cooperating with the positioning block 232, and an adjusting knob 234 located on the side of the positioning block 232 facing away from the cross plate 212 and fixedly connected to one end of the screw rod 233. The other end of the screw rod 233 is rotatably inserted into the inclined block 231 and is in limiting cooperation with the inclined block 231 along the axial direction of the screw rod 233, and the upper surface of the inclined block 231 is an inclined surface. Thus, by rotating the adjusting knob 234, the distance between the end of the screw rod 233 cooperating with the inclined block 231 and the positioning block 232 changes. When the inclined block 231 moves towards the direction close to the discharge port 430 driven by the screw rod 233, the inclined surface on the inclined block 231 will abut against the lower surface of the lifting plate 211, causing the lifting plate 211 to gradually rise; when the inclined block 231 moves towards the direction away from the discharge port 430 driven by the screw rod 233, the lifting plate 211 descends under the action of its own gravity, making the lower surface of the lifting plate 211 always abut against the inclined surface of the inclined block 231, thereby achieving the purpose of adjusting the height of the lifting plate 211. Of course, other common lifting driving structures can also be used to realize the lifting of the lifting plate 211, which will not be elaborated here.

[0035] In addition, a cushion block 221 for abutting against the product is detachably installed on one side surface of the pushing block 220 facing away from the telescopic driving member 120. The cushion block 221 is made of rubber material, PC material, silicone material or other wear-resistant materials, and the cushion block 221 is fixed on the side surface of the pushing block 220 by screws or adhered to the side surface of the pushing block 220. That is to say, the part of the pushing block 220 in contact with the product is detachable. Thus, when the cushion block 221 is worn, the damaged cushion block 221 can be directly replaced without replacing the entire pushing block 220, improving the consumable replacement efficiency and reducing the consumable usage cost.

[0036] In this embodiment, the automatic feeding structure 10 of the flat oil-removing machine further includes a flap 600 covering the top of the annular baffle 112. The flap 600 is hinged to the cover plate 300 and can rotate relative to the annular baffle 112. Preferably, the flap 600 is hinged to the cover plate 300 through a hinge 610, and the cover plate 300 is fixed to the top of the annular baffle 112 by screws to achieve the encapsulation and protection of the telescopic driving member 120 and the lifting driving member 230. In addition, on each cover plate 300, a rib 311 for receiving the product is provided on each of the two opposite sides of each through hole 310. When the product at the bottommost end in the loading area 420 falls on the cover plate 300, the product actually contacts the rib 311, so as to reduce the contact area between the cover plate 300 and the product and reduce the risk of product scratching. It should also be noted that in this embodiment, a liquid guide plate 312 is fixed to the side of the cover plate 300 facing away from the telescopic driving member 120. The upper surface of the liquid guide plate 312 is an inclined surface. Thus, a liquid guide surface is actually formed at the position of the liquid guide plate 312 corresponding to the discharge port 430, so that the liquid carried by the product itself can flow into the feeding section of the flat oil-removing machine through the liquid guide surface, so as to avoid the influence of liquid accumulation on the operation of the push block 220. Preferably, the cover plate 300 is made of aluminum or aluminum alloy material, the rib 311 is made of stainless steel material, and the flap 600 and the liquid guide plate 312 are both made of PC material.

[0037] In one embodiment, the annular baffle includes a left side plate 440 and a right side plate 450 which are oppositely arranged, a front side plate 460 located on the left side plate 440 and the right side plate 450 adjacent to one side of the loading section 20 of the flat degreasing machine and fixedly connected to the left side plate 440 and the right side plate 450, a rear side plate 470 located on the left side plate 440 and the right side plate 450 on the side opposite to the loading section 20 of the flat degreasing machine and abutting against the left side plate 440 and the right side plate 450, and a plurality of adjusting screws 480 passing through the rear side plate 470 and inserted into each partition plate 410 in a one-to-one correspondence. A plurality of first mounting grooves 461 are spaced and parallelly formed on the inner side surface of the front side plate 460, and a plurality of second mounting grooves 471 corresponding to each of the first mounting grooves 461 are spaced and parallelly formed on the inner side surface of the rear side plate 470. One side of each partition plate 410 is inserted into a first mounting groove 461, and the other side of each partition plate 410 is inserted into a second mounting groove 471. The adjusting screw 480 rotates to adjust the distance between the front side plate 460 and the rear side plate 470 to adapt to the lengths of different products. In addition, positioning columns 481 fixedly connected to the rear side plate 470 are provided on both sides of each adjusting screw 480. A spring 482 is sleeved on each positioning column 481, and one end of the positioning column 481 facing away from the rear side plate 470 is connected through a limiting connecting piece 483. The adjusting screw 480 passes through the limiting connecting piece 483 and can push the limiting connecting piece 483 to move towards the rear side plate 470 during rotation. At the same time, the limiting connecting piece 483 is slidably matched with the positioning column 481, so that when the adjusting screw 480 adjusts the rear side plate 470 to move away from the front side plate 460, the limiting connecting piece 483 is reset under the action of the spring 482. In this way, the forces on both sides of the partition plate 410 can be balanced. In this embodiment, the number of partition plates 410 and the number of loading areas 420 can be set according to the feeding requirement quantity of the docking device (the feeding belt of the flat degreasing machine).

[0038] Further, the left side plate 440, the right side plate 450, and the partition plate 410 are all in a saddle-shaped structure with a concave middle and convex sides, so that the product can be placed in the loading area surrounded by the left side plate 440 and the partition plate 410, or in the loading area surrounded by the right side plate 450 and the partition plate 410, or in the loading area surrounded by the partition plate 410 and the partition plate 410. The design of the concave middle on each plate can provide a clearance position to reduce the difficulty of taking out the product from the loading area. In addition, it should be noted that in this embodiment, the partition plate 410 is divided into a first plate body 411 and a second plate body 412. The first plate body 411 and the second plate body 412 are both movably inserted into the first mounting groove 461 and the second mounting groove 471. Among them, a plurality of first plate bodies 411 are used to partition the cavity to form a plurality of loading areas 420, and one or two second plate bodies 412 are provided in each loading area 420. By matching the second plate body 412 with the first mounting groove 461 and the second mounting groove 471 in different positions, the width of the loading area 420 can be further adjusted to adapt to the width dimensions of different products.

[0039] In one embodiment, the product placement rack 400 further includes a protective cover 490. The protective cover 490 is hingedly connected to the top of the front side plate 460 and is openably and closably disposed on the rear side plate 470. The protective cover 490 is used to block each loading area to separate the product from the external environment, avoid introducing new dirt on the product, and prevent the product from being damaged under external impact. In addition, the automatic feeding structure 10 of the flat panel degreaser further includes a sensor 700 disposed on the feeding section 20 of the flat panel degreaser and used to detect the discharging condition of the discharging port 430. The sensor 700 is electrically connected to the telescopic driving member 120. Further, the automatic feeding structure 10 of the flat panel degreaser further includes a fixed seat 710 disposed on the feeding section 20 of the flat panel degreaser and an adjusting plate 720 installed on the fixed seat 710 by screws. The sensor 700 is installed on the adjusting plate 720. During actual operation, the position of the adjusting plate 720 can be adjusted according to the front-back distance of the glass products, so that when the sensor 700 senses that there is no product, the telescopic driving member 120 runs again to push the material. Preferably, the sensor 700 is a laser sensor 700 or a displacement sensor.

[0040] Specifically, during the operation process, first, according to the size of the product to be loaded, the positions of the partition plate 410 and the rear side plate 470 are adjusted so that the size of the loading area 420 is adapted to the product size. Subsequently, according to the single-piece thickness of the product, the height of the pushing block 220 is adjusted by the lifting driving member so that the pushing block 220 can contact and push the product when pushing the material. The products are stacked in the loading area 420. If there are groove structures on the products, the groove structures can be placed at the lower part of the products so that the liquid in the grooves can be discharged through the discharging port 430. After starting the equipment, the telescopic driving member 120 pushes the sliding bracket 210 and the pushing block 220 to move, so that the pushing block 220 further pushes the lowermost product in the loading area 420 to slide until the product moves to the feeding section 20 of the flat panel degreaser through the discharging area. Subsequently, the telescopic driving member 120 drives the sliding bracket 210 and the pushing block 220 to reset, completing the loading action. When the sensor 700 does not sense the product, that is, when the sensor 700 senses that the product has completely left, a signal is sent to the telescopic driving member 120 so that the telescopic driving member 120 drives the sliding bracket 210 and the pushing block 220 to move again and push the material. Thus, the above-mentioned pushing action is repeated until all the products are exported.

[0041] The automatic loading structure 10 of the above-mentioned flat panel degreasing machine uses a telescopic driving member 120 to push the sliding bracket 210 to move, enabling the pushing block 220 to push the product at the bottom of the loading area 420 to slide, and move through the discharge port 430 to the loading section of the flat panel degreasing machine. It adopts a telescopic driving method to replace the method of sucking with a suction cup or a suction pen, which can avoid the problem of product dropping caused by abnormal vacuum, reduce the product defects caused by the product loading process, and reduce the product defect rate; its structure is simple, the production cost is low, there is no need to use a suction pen or a suction cup, avoiding frequent replacement of aging suction pens or suction cups, and reducing the equipment use cost; by pushing the product at the bottom of the loading area 420 with the pushing block 220, automatic slicing of stacked products can be achieved, without manual slicing, improving the product loading efficiency and production efficiency.

[0042] The technical features of the above-described embodiments can be combined arbitrarily. For the sake of brevity of description, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, it should be considered as the scope described in this specification.

[0043] The above-described embodiments only represent several implementation manners of the present invention, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of the utility model patent. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present invention, several modifications and improvements can still be made, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the utility model patent shall be subject to the appended claims.
