Abstract
Description
Technical Field
[0001] This utility model relates to the field of glass sandblasting technology, and in particular to a glass sandblasting loading fixture for small glass parts. Background Technology
[0002] To improve the surface properties of glass, sandblasting is often necessary. The impact of abrasive particles on the glass surface improves surface roughness and fatigue resistance, facilitating the adhesion of coatings or films, reducing residual stress, and increasing surface hardness. Currently, in the industry, when sandblasting small glass pieces, due to their small size, double-sided tape is used to adhere the glass to a mounting plate, leaving one side completely exposed for sandblasting. After sandblasting, the glass is removed, the tape is peeled off, and the sandblasting process is complete. In this fixing method, because double-sided tape is used, adhesive residue easily remains on the glass surface, requiring manual cleaning to remove it. This increases the workload of the entire sandblasting process and reduces efficiency. Furthermore, during sandblasting, some adhesive from the tape mixes with the abrasive, causing contamination and affecting the sandblasting effect. In addition, new tape needs to be applied before each sandblasting session and removed after sandblasting is completed. The high labor and tape replacement costs increase the overall cost of glass sandblasting. Utility Model Content
[0003] Therefore, it is necessary to address the above-mentioned shortcomings by providing a glass sandblasting loading fixture that reduces the workload of the entire sandblasting process, avoids sand particle contamination to improve sandblasting effect, and reduces sandblasting cost.
[0004] A glass sandblasting loading fixture includes:
[0005] A sandblasting base has several mounting grooves on its upper surface, and a through hole penetrating the lower surface of the sandblasting base is formed on the bottom surface of each mounting groove; the width of the through hole is smaller than the width of the mounting groove, so that the bottom surface of the mounting groove forms a support platform; and
[0006] The fixing component includes a number of fixing blocks that are embedded in each mounting slot and magnetically attracted to the inner surface of the mounting slot, and a number of suction cups that are fixed to the top of the fixing blocks and used to adsorb the glass sheet to be sandblasted.
[0007] In one embodiment, the support platform is provided with a first magnet, and the fixing block is a magnetic metal block.
[0008] In one embodiment, a second magnet is fixed on the support platform, and a third magnet is fixed at the bottom of the fixing block, which is magnetically attracted to the second magnet.
[0009] In one embodiment, the bottom of the fixing block is provided with a guide block for inserting into the through hole, and the outer contour shape of the guide block is adapted to the inner contour shape of the through hole.
[0010] In one embodiment, the cross-sectional shape of the fixing block is non-circular, and the inner contour shape of the mounting groove is adapted to the outer contour shape of the fixing block.
[0011] In one embodiment, the glass sandblasting loading fixture further includes a product pre-laying plate, the upper surface of which is provided with a placement area for receiving the sandblasted glass sheet, and the suction cup adsorbs the glass sheet on the product pre-laying plate when the sandblasting base is flipped and pressed onto the product pre-laying plate.
[0012] In one embodiment, the placement area has several grooves that correspond one-to-one with each mounting slot and are used to receive the sandblasted glass sheet.
[0013] In one embodiment, the upper surface of the product pre-placement plate is fixed with a plurality of limiting blocks surrounding the placement area. The width of the area enclosed by the plurality of limiting blocks is greater than or equal to the width of the sandblasting base, the length of the area enclosed by the plurality of limiting blocks is greater than or equal to the length of the sandblasting base, and the height of the limiting blocks is less than the thickness of the sandblasting base.
[0014] In one embodiment, the glass sandblasting loading fixture further includes a top plate, one side of which is provided with a plurality of top blocks for inserting into the bottom of each mounting slot in a corresponding manner after sandblasting and for lifting the glass sheet in the mounting slot.
[0015] In one embodiment, the outer contour shape of the top block is adapted to the inner contour shape of the through hole, and the sum of the heights of the top block and the guide block is greater than the depth of the through hole.
[0016] The glass sandblasting loading fixture of this utility model uses suction cups to firmly hold the glass, avoiding the problems of residual adhesive sticking to the glass and adhesive entering the machine caused by using double-sided tape. This reduces the amount of sandblasting work required to clean residual adhesive, improves sandblasting efficiency, and prevents sand particle contamination caused by adhesive mixing with sand particles, ensuring the sandblasting effect. The magnetic mounting block and suction cup clamping of the glass reduce the difficulty of loading and unloading the glass, reduce the time spent on loading and unloading, save labor costs, and eliminate the need for consumables such as tape, further reducing the cost of sandblasting operations.

[0025] To make the above-mentioned objects, features, and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a full understanding of this utility model. However, this utility model can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this utility model. Therefore, this utility model is not limited to the specific embodiments disclosed below.
[0026] Please combine Figure 1 and Figure 2This utility model discloses a glass sandblasting loading fixture, which includes a sandblasting base 100 and a fixing component 200. The sandblasting base 100 is used to load the fixing component 200 to clamp multiple glass sheets at once, thereby improving the sandblasting efficiency of the glass. The upper surface of the sandblasting base 100 has several mounting slots 110, which are arranged in a square or circular array on the upper surface of the sandblasting base 100. In this embodiment, the sandblasting base 100 has a rectangular plate structure, and the upper surface of the sandblasting base 100 has 21 mounting slots 110 arranged in a square array of 3 rows and 7 columns. In other embodiments, the number of mounting slots 110 on the sandblasting base 100 can be further adjusted according to the size of the sandblasting base 100 and the production volume requirements of the glass sandblasting operation. The mounting groove 110 has a through hole 120 penetrating the lower surface of the sandblasting base 100 on its bottom surface. The width of the through hole 120 is smaller than the width of the mounting groove 110, so that the bottom surface of the mounting groove 110 forms a support platform 130. In other words, the mounting groove 110 and the through hole 120 together form a stepped hole penetrating the upper and lower surfaces of the sandblasting base 100, thereby forming an annular support platform 130 at the bottom of the mounting groove 110. The fixing component 200 includes a plurality of fixing blocks 210 that are embedded in each mounting groove 110 and magnetically engaged with the inner surface of the mounting groove 110, and a plurality of suction cups 220 that are fixed to the top of the fixing blocks 210 and used to adsorb the glass sheet to be sandblasted. By adsorbing the glass with the suction cups 220, residual adhesive is avoided from sticking to the glass and adhesive from entering the machine. At the same time, it can also ensure that the entire surface of the glass facing away from the suction cups 220 is sandblasted to ensure the sandblasting effect. In this embodiment, the suction cup 220 is mounted on the fixing block 210 via a threaded post passing through it. By creating an installation groove 110 on the sandblasting base 100 and magnetically attaching the fixing block 210 into it, the fixing block 210 can be quickly positioned and stably clamped, while also being quickly removed from the sandblasting base 100 for easy removal of the glass sheet. In this embodiment, the through hole 120 is located in the middle of the bottom surface of the installation groove 110, ensuring that the width of the annular support platform 130 is the same at all points, thus guaranteeing stable support of the fixing block 210 by the support platform 130.
[0027] The aforementioned glass sandblasting loading fixture, by using suction cups 220 to hold the glass firmly, avoids the problem of residual adhesive sticking to the glass and adhesive entering the machine caused by using double-sided tape to adhere the glass. This reduces the increase in sandblasting workload caused by cleaning residual adhesive, improves sandblasting efficiency, and prevents sand particle contamination caused by adhesive mixing with sand particles, ensuring the sandblasting effect. By using magnetic mounting blocks 210 and suction cups 220 to clamp the glass, the difficulty of loading and unloading the glass is reduced, the time spent on loading and unloading the glass is reduced, labor costs are saved, and there is no need to use consumables such as tape, further reducing the cost of sandblasting operations.
[0028] In this embodiment, the height of the fixing block 210 is equal to or slightly less than the depth of the mounting groove 110, and the difference between the height of the fixing block 210 and the depth of the mounting groove 110 is less than the thickness of the suction cup 220. Thus, by magnetically attaching the fixing block 210, quick and individual placement and removal of single pieces of glass can be achieved. Furthermore, the magnetic attraction between the fixing block 210 and the inner surface of the mounting groove 110 ensures that the glass and the upper surface of the sandblasting base 100 are in forceful contact (abutment), preventing damage caused by glass vibration during sandblasting. In one embodiment, a first magnet is provided on the support platform 130, and the fixing block 210 is a magnetic metal block. For example, the fixing block 210 is made of iron, cobalt, or nickel. Thus, the magnetic attraction between the first magnet on the support platform 130 and the fixing block 210 allows the fixing block 210 to be clamped within the mounting groove 110. In another embodiment, a second magnet 140 is fixed on the support platform 130, and a third magnet (not shown) is fixed to the bottom of the fixing block 210, which is magnetically attracted to the second magnet 140. Preferably, in this embodiment, the fixing block 210 is made of plastic material, the bottom of the fixing block 210 is embedded and pasted with the third magnet, and the surface of the support platform 130 is embedded and pasted with the second magnet 140. In this way, while the position of the fixing block 210 is defined by the magnetic attraction between the second magnet 140 and the third magnet, the overall weight of the clamp is reduced, and the difficulty of handling the clamp is reduced.
[0029] Furthermore, in this embodiment, a guide block 230 for inserting through the through hole 120 is provided at the bottom of the fixing block 210, and the outer contour shape of the guide block 230 is adapted to the inner contour shape of the through hole 120. Preferably, the cross-section of the through hole 120 is racetrack-shaped, and the cross-section of the guide block 230 is also racetrack-shaped. By providing the guide block 230 at the bottom of the fixing block 210, the contact area between the fixing block 210 and the sandblasting base 100 is increased, thereby improving the stability of the fixing block 210 installed on the sandblasting base 100. In addition, in this embodiment, the cross-sectional shape of the fixing block 210 is non-circular, and the inner contour shape of the mounting groove 110 is adapted to the outer contour shape of the fixing block 210. Preferably, the mounting groove 110 is a circular groove, and the inner sidewall of the mounting groove 110 protrudes to form a limiting plane facing the middle of the mounting groove 110. The side of the fixing block 210 has a limiting surface that fits with the limiting plane. The limiting plane constitutes a foolproof structure of the mounting groove 110 so that the fixing block 210 can be quickly installed into the mounting groove 110 in the correct direction so that the second magnet 140 and the third magnet are aligned and attracted.
[0030] Please combine further Figure 1-2 as well as Figure 4 The glass sandblasting loading fixture also includes a product pre-laying plate 300. The upper surface of the product pre-laying plate 300 is provided with a placement area for receiving the sandblasted glass sheet. When the sandblasting base 100 is flipped and pressed onto the product pre-laying plate 300, the suction cup 220 adsorbs the glass sheet on the product pre-laying plate 300. In this embodiment, multiple glass sheets can be placed on the product pre-placement plate 300 at once. Then, the sandblasting base 100 equipped with the fixing component 200 is flipped so that the fixing component 200 faces downward and approaches the product pre-placement plate 300 until the suction cup 220 contacts the glass sheet on the product pre-placement plate 300 and the sandblasting base 100 is located above the product pre-placement plate 300. By pressing down on the sandblasting base 100, the glass sheet is squeezed and the air between the glass sheet and the suction cup 220 is expelled, thereby firmly adsorbing the glass sheet onto the suction cup 220. Then, the sandblasting base 100 is flipped again, so that multiple glass sheets can be clamped on the sandblasting base 100 at once, saving glass clamping time and improving glass clamping efficiency. In this embodiment, a number of grooves 310 are provided in the placement area, each corresponding to a mounting slot 110, for receiving the sandblasted glass sheet. When the glass sheet is installed in the groove 310, the inner wall of the groove 310 limits the glass sheet to prevent it from moving during the clamping process, thus ensuring the reliability of the glass sheet adsorption and transfer.
[0031] Furthermore, in this embodiment, a plurality of limiting blocks 320 are fixed on the upper surface of the product pre-placement plate 300, surrounding the placement area. The width of the area enclosed by the plurality of limiting blocks 320 is greater than or equal to the width of the sandblasting base 100, the length of the area enclosed by the plurality of limiting blocks 320 is greater than or equal to the length of the sandblasting base 100, and the height of the limiting blocks 320 is less than the thickness of the sandblasting base 100. Preferably, the product pre-placement plate 300 has a rectangular plate structure, and each of the four corners of the product pre-placement plate 300 is provided with an L-shaped limiting block 320. By setting the limiting blocks 320, the sandblasting base 100 can be positioned on the glass sheet taken off the product pre-placement plate 300, so that the glass sheet on the product pre-placement plate 300 is aligned with each suction cup 220 on the sandblasting base 100.
[0032] Please see Figure 1-4 The glass sandblasting loading fixture also includes a top plate 400. One side of the top plate 400 is provided with a plurality of top blocks 410 for inserting into the through holes 120 at the bottom of each mounting slot 110 after sandblasting and for lifting the glass sheets in the mounting slot 110. Furthermore, the top blocks are fixed to the top plate with screws. The outer contour shape of the top block 410 is adapted to the inner contour shape of the through hole 120, and the sum of the heights of the top block 410 and the guide block 230 is greater than the depth of the through hole 120. That is to say, the cross-section of the top block 410 is also a racetrack-shaped structure. By setting a top plate 400 and clamping several top blocks 410 on it, after the glass sheet is sandblasted, the sandblasting base 100 can be placed on the top plate 400, so that each top block 410 corresponds to each through hole 120 on the sandblasting base 100. Then, the top plate 400 is pressed against the lower surface of the sandblasting base 100 or the sandblasting base 100 is pressed against the upper surface of the top plate 400. The top blocks 410 can then push out each fixing block 210 along with the suction cup 220 on the fixing block 210 and the glass sheet, so as to remove the product. In this embodiment, by setting a product pre-placement plate 300 and a top plate 400, the batch clamping of glass sheets can be completed at one time. After sandblasting is completed, the glass sheets can be removed from the sandblasting base 100 in batches at one time, which improves the efficiency of glass loading and unloading operations.
[0033] Please combine Figure 4-8Before the glass sandblasting operation, the product pre-layout plate 300 is first placed on the worktable, and several glass sheets 10 to be sandblasted are placed one by one into the grooves 310 on the product pre-layout plate 300. The fixing blocks 210 equipped with suction cups 220 are then embedded one by one into the mounting grooves 110 of the sandblasting base 100, and the fixing blocks 210 are magnetically attracted to the inner surface of the mounting grooves 110. The entire sandblasting base 100 is then flipped over so that it is above the suction cups 220. The sandblasting base 100 is positioned by the limiting blocks 320 on the product pre-layout plate 300 and pressed firmly onto the product pre-layout plate 300, so that the glass sheets 10 are adsorbed onto the suction cups 220. After the suction cups 220 adsorb the glass sheets 10, the sandblasting base 100 is lifted and flipped over again, and then sent into the sandblasting machine for sandblasting. After sandblasting is completed, place the sandblasting base 100 on the top plate 400 and press the sandblasting base 100 so that the top plate 410 lifts the fixing block 210. The glass sheet 10 can then be removed together with the fixing block 210 to facilitate the centralized handling of the glass sheet 10 and the use of the sandblasting base 100 for the next batch of glass sandblasting operations.
