[0029] In the description of this application, unless otherwise clearly defined, terms such as setting, installing, and connecting should be understood in a broad sense, and technicians in the relevant technical field can reasonably determine the specific meanings of the above terms in this application based on the specific content of the technical solution.

[0030] The following is the attached Figure 1 To the attached Figure 7 , describing the flat grinding material removal fixture group of an embodiment of the present application.

[0031] Reference Figure 1 、 Figure 3 、 Figure 4 and Figure 5 The flat grinding and retrieving jig group of this embodiment includes a flat grinding jig 100, a ejecting jig 300, a product positioning plate 200 and a retrieving device 400, wherein the flat grinding jig 100 is provided with a plurality of fixed positions on the top, which are used to fix the workpiece, and an ejection hole 110 extending to the bottom surface of the flat grinding jig 100 is provided below each of the fixed positions; the product positioning plate 200 is detachably connected to the flat grinding jig 100, and a through hole 210 is opened at the position corresponding to the fixed position; a plurality of ejector pins 310 are provided on the top of the ejecting jig 300, and the ejector pins 310 are arranged one by one with the ejection holes 110, and are used to eject the workpiece in the fixed position and enter the through hole 210; the retrieving device 400 is used to suck the workpiece in the through hole 210. By arranging the flat grinding jig 100, the product positioning plate 200, the ejection jig 300, and the pick-up device 400, after flat grinding, the product positioning plate 200 is mounted on the side of the flat grinding jig 100 where the workpiece was ground. The ejector pin 310 is inserted through the ejection hole 110, allowing the workpiece to protrude from the flat grinding jig 100 and be received in the through hole 210 of the product positioning plate 200. The pick-up device 400 then picks up the workpiece from the through hole 210, allowing for quick removal of small workpieces. This also reduces damage to the workpiece.

[0032] It is understood that the pick-up device 400 includes a suction plate 410 having a groove 412 formed therein. The groove 412 corresponds to the through hole 210 in the product positioning plate 200. The groove 412 guides the workpiece in the through hole 210, thereby positioning the workpiece during suction and preventing it from falling off the pick-up device 400 due to vibration or collision.

[0033] Combine Figure 1 and Figure 6 In the retrieving device 400 of this embodiment, the distance between the grooves 412 corresponds to the through-holes 210 on the product positioning plate 200. Multiple grooves 412 are provided, allowing for simultaneous pickup of workpieces from a row of the product positioning plate 200. It is understood that the size of the retrieving device 400 can be increased to simultaneously pickup multiple rows of workpieces from the product positioning plate 200. Furthermore, multiple flat grinding jigs 100, product positioning plates 200, and ejecting jigs 300 can be used simultaneously, while the size of the retrieving jig can be increased to simultaneously pickup all workpieces from multiple flat grinding jigs 100. This increases the number of workpieces that can be picked up at once, thereby improving retrieving efficiency.

[0034] It can be understood that the material picking device 400 also includes a quick connector 420 and a vacuum generator. The suction plate 410 is provided with a suction hole 411, which is connected to the vacuum generator through the quick connector 420, and then the product is sucked by vacuum to avoid damaging the surface of the workpiece that has been flat-ground during the material picking process.

[0035] Combine Figure 6 The retrieving device 400 of this embodiment is also provided with a handle to facilitate the placement and movement of the retrieving device 400. It is understood that the retrieving device 400 may also include a manual valve, which can be switched on and off to quickly discharge the material. Specifically, the suction plate 410 is detachably mounted on the retrieving device 400, and the handle and quick connector 420 are mounted on the side of the retrieving device 400 away from the suction plate 410. When changing the workpiece being flat-ground, only the suction plate 410 needs to be replaced, which is convenient and quick, reducing the manufacturing cost of the retrieving device 400.

[0036] It is understood that the flat grinding jig assembly also includes a first locating pin, a first locating hole 220 is defined in the product locating plate 200, and a second locating hole 120 is defined in the flat grinding jig 100. The first locating pin can be sequentially inserted into the first locating hole 220 and the second locating hole 120 to allow the product locating plate 200 to be mounted on the flat grinding jig 100. The structure of the locating pin and locating hole is relatively simple, which helps reduce the production cost of the jig.

[0037] Combine Figure 1 、 Figure 4 and Figure 5 In this embodiment, the positions of the first positioning hole 220 and the second positioning hole 120 correspond to each other, which is beneficial for the product positioning plate 200 to position the product and improves the accuracy of the product positioning plate 200 in positioning the product.

[0038] It can be understood that the product positioning plate 200 is provided with a third positioning hole 230, the flat grinding jig 100 is provided with a fourth positioning hole 130, and the ejecting jig 300 is provided with a second positioning pin 320. The second positioning pin 320 can be passed through the fourth positioning hole 130 and the third positioning hole 230 in sequence, so that when the flat grinding jig 100 is placed on the ejecting jig 300, accurate positioning between the flat grinding jig 100 and the ejecting jig 300 can be achieved.

[0039] Combine Figure 1 and Figure 3The product positioning plate 200 and the flat grinding jig 100 each have third positioning holes 230 and fourth positioning holes 130 at their four corners. The ejection jig 300 is equipped with second positioning pins 320 corresponding to the third and fourth positioning holes 230 and 130. The second positioning pins 320, in concert with the third and fourth positioning holes 230 and 130, facilitate the guidance of the ejector pin 310 into the ejection hole 110, thereby improving the overall accuracy of the jig assembly. The number and location of the third and fourth positioning holes 230 and 130, respectively, are not specifically limited, as long as they cooperate with each other.

[0040] It is understood that the ejection jig 300 is provided with a protrusion 330, which protrudes from the ejection jig 300 and is capable of abutting against the flat grinding jig 100. When the ejector pin 310 is inserted into the ejection hole 110, the protrusion 330 creates a certain gap between the ejection jig 300 and the flat grinding jig 100, which facilitates separation of the flat grinding jig 100 from the ejection jig 300 after the material is removed.

[0041] It is understood that the height of the protrusion 330 is adjustable. The height of the protrusion 330 can be adjusted according to the size of the workpiece. When the flat grinding jig 100 is grinding a tall workpiece, the height of the protrusion 330 can be lowered to increase the depth of the ejector pin 310 entering the ejection hole 110, thereby increasing the height of the workpiece and allowing it to better protrude from the flat grinding jig 100. Conversely, when the flat grinding jig 100 is grinding a shorter workpiece, the height of the protrusion 330 can be raised to reduce the depth of the ejector pin 310 entering the ejection hole 110, thereby reducing the height of the workpiece, preventing the workpiece from separating from the product positioning plate 200 and facilitating the positioning of the workpiece by the product positioning plate 200.

[0042] It is understood that the flat grinding reclaiming fixture assembly also includes a first base 500, to which the ejecting fixture 300 is mounted. The first base 500 is provided with a first positioning structure 510, and the reclaiming device 400 is provided with a second positioning structure 430 that cooperates with the first positioning structure 510. The first positioning structure 510 and the second positioning structure 430 facilitate better positioning of the reclaiming device 400 during reclaiming, thereby improving the accuracy of the fixture assembly in positioning and sucking the workpiece.

[0043] It is understandable that the flat grinding material taking jig group also includes a cleaning jig, which includes a second base 600 and a cleaning disc 700. The cleaning disc 700 is installed on the second base 600. The second base 600 is provided with a third positioning structure 610 and can cooperate with the second positioning structure 430.

[0044] Combine Figure 1 and Figure 6In this embodiment, the first positioning structure 510 is a positioning hole, and the second positioning structure 430 is a positioning pin. The pin-hole combination can be well positioned and the structure is relatively simple, which can improve the accuracy of the fixture assembly in positioning and sucking the workpiece, and can also reduce the production cost of the fixture. Figure 7 , the third positioning structure 610 of this embodiment is also a positioning hole.

[0045] It is understandable that in addition to the above-mentioned combination of positioning pins and positioning holes, in some other examples, the second positioning structure 430 can also be other structural types such as magnets, and the first positioning structure 510 and the third positioning structure 610 can also be reasonably selected according to the type of the second positioning structure 430. For example, when the second positioning structure 430 is a magnet, the first positioning structure 510 and the third positioning structure 610 can be magnets that cooperate with it or iron metals that can be adsorbed by magnets.

[0046] Although the embodiments of the present application have been shown and described, those skilled in the art will appreciate that various changes, modifications, substitutions, and variations may be made to the embodiments without departing from the principles and intent of the present application, and that the scope of the present application is defined by the claims and their equivalents.
