Description

Technical Field

[0001] The utility model belongs to the technical field of grinding processing, and in particular relates to a through-type slice grinding machine. Background Art

[0002] At present, the grinding process of sheet products is generally carried out by a planetary wheel double-sided grinder. However, in some industries, due to design requirements, the thickness of products is getting thinner and thinner. For example, the heat sink material products used in the electronic packaging industry are too thin and are easily damaged by external forces, especially thin sheets with a thickness of ≤0.2mm. When the aforementioned planetary wheel double-sided grinder is used for the above-mentioned thin sheet products, the product is located in the hole of the planetary wheel, and the thickness of the matching planetary wheel can only be less than or equal to the thickness of the thin sheet product being ground. Even if a material with higher hardness is selected, the planetary wheel will be easily broken or deformed due to force when it rotates with the meshing of the gears in the grinder, which will eventually cause the grinder chuck and the product to be damaged and scrapped, resulting in instability in the grinding process of thin sheet products, affecting the stability of thin sheet product production, and resulting in a low pass rate for thin sheet products. Utility Model Content

[0003] The technical problem to be solved by the utility model is to provide a through-type thin-sheet grinder which ensures the grinding efficiency on the basis of improving the grinding qualification rate of thin-sheet target grinding products and has a simpler overall structure.

[0004] The content of the utility model includes a grinding disc, a fixed disc and a feeding mechanism. The grinding disc is located above the fixed disc and can rotate around its own axis. The middle part of the fixed disc is through-set to form a feeding hole. A grinding groove for accommodating a target grinding product is provided on one side of the fixed disc facing the grinding disc. The depth of the grinding groove is less than or equal to the thickness of the target grinding product, and one end of the grinding groove is connected to the feeding hole, and the other end is connected to the side of the fixed disc. The feeding mechanism is used to drive the target grinding product to enter the grinding groove from the side of the fixed disc and move toward the feeding hole in the grinding groove.

[0005] Furthermore, the feeding mechanism includes a guide platform and a feeding piece, the guide platform is located on the side of the fixed plate, and a material guide groove is provided on the guide platform, one end of the material guide groove is connected to the grinding groove, and when a plurality of target grinding products are located in the material guide groove, they are arranged in sequence along the length direction of the material guide groove, and the feeding piece drives the plurality of target grinding products in the material guide groove to move toward the grinding groove.

[0006] Furthermore, the width of the material guiding groove is the same as the width of the grinding groove.

[0007] Furthermore, the feeding member is a roller, which is located above the material guide trough. When the roller rotates, its wheel surface contacts one of the target grinding products in the material guide trough and drives the target grinding product to move toward the grinding trough, thereby pushing other target grinding products located in front of the moving direction of the target grinding product to continue to move toward the grinding trough.

[0008] Furthermore, the wheel surface of the roller is made of silicone material or rubber material.

[0009] Furthermore, it also includes a collecting box, which is located below the feeding hole and is used to collect the target ground product falling along the feeding hole.

[0010] Furthermore, a liquid medium is provided in the collecting box for buffering the target ground product falling along the discharge hole.

[0011] Furthermore, it also includes a driving mechanism for driving the grinding disc to rotate.

[0012] Furthermore, it also includes an adjusting mechanism for driving the grinding disc to move so as to adjust the distance between the grinding disc and the fixed disc.

[0013] Furthermore, it also includes a support seat and a protective cover, wherein the fixed disk and the protective cover are arranged on the support seat, and the fixed disk and the grinding disk are both located in the protective cover.

[0014] The beneficial effect of the utility model is that when in use, the feeding mechanism drives the target grinding product to enter the grinding groove from the side of the fixed disk, and the target grinding product entering the grinding groove grinds its surface under the action of the grinding disk, and moves toward the discharge hole in the grinding groove under the continuous drive of the feeding mechanism, and finally the ground target grinding product falls out of the discharge hole. For target grinding products with thinner thickness, grinding grooves of corresponding depths can be set accordingly, and the thickness size restriction of the fixed disk is small, and there will be no problems such as deformation and breakage of the planetary wheel of the planetary wheel grinding equipment, resulting in jamming and product scrapping. The grinding process and the stability of the production of target grinding products are higher, and the qualified rate of target grinding products is improved. Based on the setting of the feeding mechanism, the grinding groove and the discharge hole on the fixed plate, it can be ensured that the target grinding product can be continuously fed between the fixed plate and the grinding plate for grinding processing, and the target grinding product that has been ground can be pushed directly out of the discharge hole by the subsequent second grinding product entering the grinding groove. There is no need to move the grinding plate and then take out and put in the target grinding products one by one, which saves operation time. On the basis of improving the grinding processing qualification rate of thin-sheet target grinding products, the grinding processing efficiency is guaranteed, and the overall structure is simpler.

[0020] like Figure 1-Figure 4 As shown, the utility model provides a through-type thin-sheet grinder, including a grinding disc 4, a fixed disc 3 and a feeding mechanism. The grinding disc 4 is located above the fixed disc 3 and can rotate around its own axis, that is, the fixed disc 3 remains stationary, and the grinding disc 4 rotates. The material of the grinding disc 4 can be composed of embedded abrasives and adhesives. The fixed disc 3 is through-set in the middle to form a feed hole 302. The fixed disc 3 is provided with a grinding groove 301 for accommodating a target grinding product 100 on one side facing the grinding disc 4. The setting of the grinding groove 301 can position and guide the target grinding product 100 during the grinding process to prevent the target grinding product 100 from moving laterally during the grinding process. In order to ensure that the grinding disc 4 can effectively act on the surface of the target grinding product 100, the depth of the grinding groove 301 is less than or equal to the thickness of the target grinding product 100. One end of the grinding groove 301 is connected to the feeding hole 302, and the other end is connected to the side of the fixed plate 3. The feeding mechanism is used to drive the target ground product 100 to enter the grinding groove 301 from the side of the fixed plate 3 and move toward the feeding hole 302 in the grinding groove 301. In order to ensure that the target ground product 100 can smoothly pass through the feeding hole 302, the diameter of the feeding hole 302 is greater than the width or diameter of the target ground product 100. When the target ground product 100 is a quadrilateral, it is further preferred that the diameter of the feeding hole 302 is greater than the diagonal size of the target ground product 100.

[0021] When in use, the feeding mechanism drives the target ground product 100 to enter the grinding groove 301 from the side of the fixed disk 3. The target ground product 100 entering the grinding groove 301 grinds its surface under the action of the grinding disk 4, and moves toward the discharge hole 302 in the grinding groove 301 under the continuous drive of the feeding mechanism, and finally the ground target ground product 100 falls out of the discharge hole 302. For target ground products 100 with thinner thickness, it is sufficient to set a grinding groove 301 of corresponding depth, and the thickness size restriction of the fixed disk 3 is small, and there will be no problems such as deformation and breakage of the planetary wheel of the planetary wheel grinding equipment, resulting in jamming and product scrapping. The grinding process and the production of the target ground product 100 are more stable, and the qualified rate of the target ground product 100 is improved. Based on the setting of the feeding mechanism, the grinding groove 301 and the discharge hole 302 on the fixed disk 3, it can be ensured that the target ground product 100 can be continuously fed between the fixed disk 3 and the grinding disk 4 for grinding processing, and the target ground product 100 that has been ground can be pushed by the subsequent second ground product entering the grinding groove 301 and can be directly dropped out of the discharge hole 302. There is no need to move the grinding disk 4 and then take out and put in the target ground products 100 one by one, which saves operation time, ensures the grinding processing efficiency on the basis of improving the grinding processing pass rate of thin-sheet target ground products 100, and the overall structure is simpler.

[0022] In the present invention, the feeding mechanism includes a guide platform 5 and a feeding member 6. The guide platform 5 is located on the side of the fixed plate 3. A guide groove is provided on the guide platform 5. One end of the guide groove is connected to the grinding groove 301. When a plurality of target grinding products 100 are located in the guide groove, they are arranged in sequence along the length direction of the guide groove. The feeding member 6 drives the plurality of target grinding products 100 in the guide groove to move toward the grinding groove 301. The setting of the guide groove and the feeding member 6 can ensure the orderly and continuous feeding in the grinding groove 301. When the grinding groove 301 is continuously fed, the target grinding product 100 that has been ground is pushed toward the discharge hole 302 by the target grinding product 100 that subsequently enters the grinding groove 301 and falls out.

[0023] The width of the grinding groove 301 matches the width or diameter of the target grinding product 100. The specific width of the grinding groove 301 is determined according to the width or diameter of the actual target grinding product 100. The width is set to allow the target grinding product 100 to move in and out, but the target grinding product 100 cannot have obvious lateral displacement in the grinding groove 301. For example, it is set to be 1-2 mm larger than the width of the target grinding product 100. Preferably, the width of the guide groove is the same as the width of the grinding groove 301. On the one hand, it can ensure that the target grinding product 100 is fed into the grinding groove 301 in a specified posture. On the other hand, it can avoid the situation where the target grinding product 100 is stuck and cannot enter the grinding groove 301 normally due to the presence of a step at the connection between the guide groove and the grinding groove 301. The target grinding product 100 is fed into the guide groove along the end of the guide groove away from the fixed plate 3 by an external feeding device.

[0024] The feeding member 6 is a roller, which is located above the material guide groove. When the roller rotates, its wheel surface contacts one of the target grinding products 100 in the material guide groove and drives the target grinding product 100 to move toward the grinding groove 301 under the action of friction. When the target grinding product 100 moves toward the grinding groove 301, it pushes other target grinding products 100 located in front of the target grinding product 100 in the moving direction to continue moving toward the grinding groove 301. At this time, the target grinding product 100 located in the front in the moving direction of the target grinding product 100 is the target grinding product 100 that is in the grinding groove 301 and has been ground. It falls out along the discharge hole 302 under the push.

[0025] Preferably, the wheel surface of the roller is made of silicone or rubber material, so that the wheel surface of the roller has a certain degree of softness, increases the friction between the roller and the target grinding product 100, and ensures that the target grinding product 100 can move forward with the rotation of the roller. In the present utility model, the roller can only have a layer of silicone or rubber material on the wheel surface, or the entire roller can be made of silicone or rubber material, such as a silicone wheel. The roller is specifically driven to rotate by a motor, and the motor is installed on the guide platform 5.

[0026] The utility model further includes a collection box 7, which is located below the discharge hole 302 and is used to collect the ground target abrasive product 100 that falls along the discharge hole 302. The collection box 7 is provided with a liquid medium, which is used to buffer the ground target abrasive product 100 that falls along the discharge hole 302, to prevent the ground target abrasive product 100 from being bumped, and to prevent the ground target abrasive product 100 from being exposed to the air and causing oxidation. The liquid medium may be a degreasing cleaning agent or others.

[0027] The utility model also includes a driving mechanism for driving the grinding disc 4 to rotate. In one embodiment of the utility model, the driving mechanism is a driving motor 8, which directly drives the grinding disc 4 to rotate. In another embodiment of the utility model, the driving mechanism specifically includes a driving motor 8 and a transmission assembly 9, the driving motor 8 is located on one side of the grinding disc 4, and the driving motor 8 drives the grinding disc 4 to rotate through the transmission assembly 9, and the transmission assembly 9 can be a pulley transmission assembly 9 or other. Taking the transmission assembly 9 as a pulley transmission assembly 9 as an example, the driving motor 8 is installed on the support seat 1, the grinding disc 4 is rotatably set on the protective cover 2 or is rotatably set on the support seat 1 through a bracket, the driving wheel in the pulley assembly is set on the output end of the driving motor 8, and the driven wheel is set on the grinding disc 4.

[0028] In one embodiment of the utility model, the distance between the grinding disc 4 and the fixed disc 3 is a fixed value. In an optional embodiment, an adjusting mechanism is also included, which is used to drive the grinding disc 4 to move up and down to adjust the distance between the grinding disc 4 and the fixed disc 3, so as to adjust the specific grinding size and adapt to different grinding requirements. Specifically, the adjusting mechanism can be a linear moving module. In this embodiment, the driving mechanism and the grinding disc 4 are both arranged on the moving end of the linear moving module, and the grinding disc 4 is driven to move by the linear moving module to adjust the distance from the fixed disc 3. In other embodiments of the utility model, the driving mechanism specifically includes a driving motor 8 and a transmission assembly 9, and the driving motor 8 drives the grinding disc 4 to rotate through the transmission assembly 9. In other embodiments, the adjusting mechanism can be a screw adjusting mechanism or others, which can meet the up and down movement of the grinding disc 4, and is not specifically limited here.

[0029] The utility model also includes a support seat 1 and a protective cover 2. The support seat 1 is used to support the whole machine. Its material can be selected from a hard alloy material with high strength. Preferably, its material is a high-strength integral steel casting. The fixed disk 3 and the protective cover 2 are arranged on the support seat 1, and the fixed disk 3 and the grinding disk 4 are both located in the protective cover 2. The protective cover 2 can play a role of safety protection above the fixed disk 3 and the grinding disk 4. Its material can be selected from a hard alloy material with high strength, such as stainless steel. An electric control box 10 is arranged on the protective cover 2, and the driving motor 8 in the driving mechanism and the motor for driving the roller to rotate are both electrically connected to the electric control box 10.

[0030] In the present invention, the length dimension of the grinding groove 301 is the dimension between the grinding groove 301 located at the feeding hole 302 and the side of the fixed plate 3, and the direction on the target ground product 100 that is in the same direction as the length of the grinding groove 301 is the length of the target ground product 100. The length of the grinding groove 301 can be the same as or greater than the length of the target ground product 100. The specific roller operation mode can be continuous feeding or intermittent feeding.

[0031] When the roller is in continuous feeding mode, the roller rotates continuously to push the target grinding product 100 in the guide groove 501 into the grinding groove 301. The target grinding product 100 in the grinding groove 301 is subjected to the action of the grinding disc 4 to complete the surface grinding process, and falls out of the discharge hole 302 into the collection box 7 under the continuous advancement of the target grinding product 100 at the rear. At the same time, the next target grinding product 100 is pushed forward to the original position of the previous target grinding product 100, thereby realizing continuous grinding processing feeding and discharging.

[0032] When the roller operation mode is intermittent feeding, a single rotation of the roller pushes the target grinding product 100 in the guide groove 501 into the grinding groove 301 by a certain distance, which is the same as or slightly larger than the length of the target grinding product 100. After the target grinding product 100 in the grinding groove 301 is subjected to the action of the grinding disc 4 and completes the surface grinding process, the roller rotates once, and the target grinding product 100 after the surface grinding process is thrust and falls out of the discharge hole 302 into the collection box 7. At the same time, the next target grinding product 100 is pushed forward to the original position of the previous target grinding product 100, thereby realizing intermittent continuous grinding feeding and discharging.
