Description

Technical Field

[0001] This invention relates to the field of material receiving devices, and in particular to a material receiving device used in a glass polishing machine. Background Technology

[0002] Tempered glass screen protectors are protective films applied to mobile phone screens. Structurally, they mainly consist of an outer layer of tempered glass: tempered glass that provides screen protection and impact resistance; a middle layer of plastic or resin: increasing toughness and preventing injury from shattered glass; and a bottom adhesive layer: using adhesive to bond to the screen for a secure hold. During the production of tempered glass screen protectors, the initial step is processing the outer tempered glass. This process, aside from cutting the glass sheets, involves transferring each cut sheet individually to a glass polishing device for subsequent polishing and grinding.

[0003] Currently, after the glass sheets are polished, a receiving device is needed on the tempered glass film polishing equipment to collect and store the polished glass sheets. During collection and storage, because the glass sheets have a smooth surface, they cannot be glued together; they must be arranged separately. If the glass sheets are glued together, they will adhere, making them difficult to separate and causing scratches. Ideally, the receiving device should only support the two sides of the glass sheet, leaving the middle unsupported. However, supporting only the sides introduces instability during insertion, making it easy for the glass sheet to detach from its placement due to inaccurate positioning or misalignment. Therefore, these issues present a significant challenge.

[0004] Therefore, it is necessary to provide a receiving device that meets the design requirements. Summary of the Invention

[0005] In view of the shortcomings of the prior art, the purpose of this invention is to provide a material receiving device for use in a glass polishing machine.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A receiving device for a glass polishing machine includes a material box and a frame. Two synchronously moving belts are mounted on the frame. Each belt has a placement position for a single material box. The material box is a frame. At least two first horizontal bars are provided at the top of the material box, and at least two second horizontal bars are provided at the bottom. Several grooves for accommodating single glass sheets are evenly distributed on the first and second horizontal bars. Clearances, with spacing adapted to the width of the glass sheets, are provided between the first and second horizontal bars. A receiving station is provided on the frame. The receiving station has symmetrically arranged first and second base plates. A first cylinder is mounted on the first base plate to push the material box. A pushing rod is mounted on the push head of the first cylinder. An "L"-shaped stop is provided at the edge facing the discharge direction. A rotary clamping cylinder is provided on the side of the first substrate and the second substrate facing the receiving direction. A second cylinder is provided on the symmetrical end of the second substrate relative to the rotary clamping cylinder. The push head of the second cylinder is provided with a limit block. The second substrate is provided with a clearance hole relative to the limit block. Under the push of the second cylinder, the limit block can extend out of the clearance hole and be placed on the inner end face of the second substrate, or it can retract and be stored in the clearance hole. A mounting plate is provided between the receiving station and the synchronous belt of the frame. A third cylinder is provided on the mounting plate. A panel is connected to the push head of the third cylinder. A guide comb that can be inserted into the clearance is provided on the panel. The spacing between the comb teeth of the guide comb is adapted to the insertion of a single glass sheet.

[0008] Preferably, the guide comb is made of PVDF sheet.

[0009] Preferably, the panel has vertically erected uprights corresponding to the number of guide combs, and a water collection groove is provided between the comb teeth of the guide comb. The guide comb is installed on the side of the top of the uprights, so that the top of the uprights is flush with the opening of the water collection groove.

[0010] Preferably, a roller is provided at the end of the stop block, and the surface of the roller extends beyond the inner end face of the stop block.

[0011] Preferably, the placement position includes protrusions disposed on the timing belt, and the distance between every two protrusions is adapted to the length of the material box.

[0012] Preferably, the timing belt is an annular timing belt, and the protrusion is detachably mounted on the timing belt by fasteners.

[0013] Preferably, the first substrate and the second substrate are fixedly installed on the receiving station using a combination of strip holes, bolts, and threaded holes.

[0014] Preferably, the second substrate has an outwardly protruding receiving block at the location opposite the push rod, and both ends of the receiving block are connected to the inner end face of the second substrate through guide ramps.

[0015] By adopting the above-mentioned solution, the present invention utilizes the toothed groove design of the material box to allow for the isolated placement of glass sheets, with contact only at the edges of the glass sheets, reducing scratches on the glass sheet surface and lowering the risk of scratches. At the same time, the linkage of multiple cylinders enables the positioning and clamping of the material box, ensuring that the material box is in the correct position. Furthermore, the guide comb allows for the precise and vertical placement of the glass sheets into the material box, enabling the glass sheets to be placed more stably and effectively during insertion.

[0024] like Figures 1 to 5As shown in the figure, this embodiment provides a receiving device for a glass polishing machine, including a material box 1 and a frame 2. The frame 2 is equipped with two synchronously moving belts 3, each with a placement position for a single material box 1. The material box 1 is a frame, with at least two first horizontal bars 11 at its top and at least two second horizontal bars 12 at its bottom. The first and second horizontal bars 11 and 12 are evenly distributed with several grooves 14 capable of accommodating a single glass sheet 100. Clearances 13, with spacing adapted to the width of the glass sheet 100, are provided between the first and second horizontal bars 11 and between the second and second horizontal bars 12. The frame 2 is equipped with a receiving station, which has symmetrically arranged first base plates 4 and 5. The first base plate 4 is equipped with a first cylinder 41 that pushes the material box 1, and the push head of the first cylinder 41 is equipped with a push rod 42. The push rod 42 has an "L"-shaped stop 43 on its side facing the discharge direction. The first substrate 4 and the second substrate 5 each have a rotary pressing cylinder 6 on their sides facing the receiving direction. The second substrate 5 has a second cylinder 51 on its symmetrical end relative to the rotary pressing cylinder 6. The push head of the second cylinder 51 has a limit block 52. The second substrate 5 has a clearance hole relative to the limit block 52, so that the limit block 52 can extend out of the clearance hole and be placed on the inner end face of the second substrate 5 under the push of the second cylinder 51, or it can retract and be stored in the clearance hole. The frame 2 has a mounting plate 7 between the receiving station and the synchronous belt 3. The mounting plate has a third cylinder 71. The push head of the third cylinder 71 is connected to a panel 72. The panel 72 has a guide comb 73 that can be inserted into the clearance. The spacing between the comb teeth 74 of the guide comb 73 is adapted to the insertion of a single glass sheet 100.

[0025] This embodiment utilizes the toothed groove 14 design of the material box 1 to allow the glass sheets 100 to be placed in isolation one by one, and only contact the edges of the glass sheets 100, reducing scratches on the surface of the glass sheets 100 and lowering the risk of scratches. At the same time, the material box 1 is positioned and clamped by the linkage of multiple cylinders, ensuring that the material box 1 is in the correct position. With the help of the guide comb 73, the glass sheets 100 can be accurately and vertically placed one by one into the material box 1, allowing the glass sheets 100 to be placed more stably and effectively.

[0026] In practice, the material box 1 is first placed on the timing belt 3, which then moves the material box 1 under the operation of the timing belt 3. When the material box 1 moves to the receiving station, it stops moving. The first cylinder 41 and the second cylinder 51 push outward, so that the limiting block 52 and the stop block 43 are located on one side of the material box 1. The push rod 42 pre-presses the material box 1 to keep it in a preliminary position. Then, the two rotary clamping cylinders 6 work synchronously, and together with the blocking of the limiting block 52 and the stop block 43, they can clamp the material box 1, thus achieving clamping and positioning of the material box 1 in four directions. Then, the third cylinder 71 operates, aligning the guide comb 73 with the clearance 13 of the material box 1, specifically between the first horizontal bar 11 and the second horizontal bar 12. Simultaneously, the spacing between the comb teeth 74 of the guide comb 73 corresponds to the tooth groove 14. When the glass sheet 100 is inserted from above, it first inserts into the tooth groove 14 of the first horizontal bar 11. Then, because the comb teeth 74 of the guide comb 73 are aligned with the tooth groove 14, the glass sheet 100 immediately enters the guide box. Between the comb teeth 74 of the comb 73, the glass sheet 100 is guided during insertion. Without the comb teeth 74, the glass sheet 100 is easily misaligned during insertion and cannot be inserted into the tooth groove 14 of the second horizontal bar 12. With the comb teeth 74 as a guide, the glass sheet 100 can fall smoothly into the tooth groove 14 of the second horizontal bar 12 after entering the gap between the comb teeth 74, thus completing the placement of the glass sheet 100. When the material box 1 is full of glass sheets 100, the third cylinder 71 retracts, the guide comb 73 is pushed out of the clearance 13, that is, it is removed from the material box 1. Then the first cylinder 41 and the second cylinder 51 retract, the rotating clamping cylinder 6 is reset, the locking of the material box 1 is released, and finally, under the conveying of the synchronous belt 3, it leaves the receiving station, which then waits for the next material box 1.

[0027] Furthermore, to reduce the adsorption force between the glass sheets 100, the guide comb 73 in this embodiment is made of PVDF sheet. Using PVDF material can also avoid absorbing or adsorbing water. Because water is needed when the tempered film polishing machine polishes the glass sheets, the processed glass sheets 100 will have some water on them, which will cause water to remain on the guide comb 100. Using PVDF material makes it easy to clean the water remaining on the guide comb 73. The most convenient method is to blow it away directly with an air gun. It can be cleaned once after each material box 1 is placed.

[0028] Furthermore, to prevent water from accumulating at the bottom of the glass sheet 100, the panel 72 in this embodiment is vertically equipped with uprights 75 in a number corresponding to the guide combs 73. A water-collecting groove 76 is provided between the comb teeth 74 of the guide comb 73. The guide comb 73 is installed on the side of the top of the uprights 75, so that the top of the uprights 75 is flush with the opening of the water-collecting groove 76. Thus, when the glass sheet 100 is placed on it, the bottom of the glass sheet 100 will rest against the top of the uprights 75. If there is water on the glass sheet 100 or on the guide comb 73, it will gradually flow into the water-collecting groove 76, preventing water from stagnating at the bottom of the glass sheet 100, thereby achieving the function of draining water. Of course, if necessary, a water collection box can be installed here to prevent water from flowing onto the ground. The water collection box, through a water pipe, guides the water to a wastewater tank, and the water collection box can be designed with a certain slope.

[0029] Furthermore, when the first cylinder 41 pushes out or retracts, the stop block 43 will contact the material box 1. In order to reduce the frictional resistance during the movement of the stop block 43, a roller 44 is provided at the end of the stop block 43 in this embodiment. The wheel surface of the roller 44 extends beyond the inner end face of the stop block 43. In this way, the roller 44 presses against the material box 1, so that even if the material box 1 is fastened at the other end, the first cylinder 1 can still smoothly control the movement of the stop block 43.

[0030] Furthermore, regarding the design of placing the material box 1 on the timing belt 3, the placement position can include protrusions 31 set on the timing belt 3, and the distance between every two protrusions 31 is adapted to the length of the material box 1. In this way, the four protrusions 31 on the two timing belts 3 form a support for the four corners of the material box 1, thereby initially limiting the material box 1 to move with the timing belt 3.

[0031] Furthermore, in this embodiment, the timing belt 3 is an annular timing belt, and the protrusion 31 is detachably installed on the timing belt 3 by fasteners (such as bolts). With this design, on the one hand, the protrusion 31 can be flexibly replaced according to the degree of wear, or the protrusion 31 of different lengths can be replaced according to the length of the material box 1, that is, the distance between the protrusion 31 and the protrusion 31 can be changed.

[0032] Furthermore, in this embodiment, the first substrate 4 and the second substrate 5 are fixedly installed on the receiving station using a combination of strip holes 8, bolts, and threaded holes. In this way, the installation positions of the first substrate 4 and the second substrate 5 can be finely adjusted by relying on the design of the strip holes 8.

[0033] Furthermore, in this embodiment, the second substrate 5 is provided with an outwardly protruding receiving block 53 opposite the push rod 42. Both ends of the receiving block 53 are connected to the inner end face of the second substrate 5 via guide ramps 54. When the rotary clamping cylinder 6 presses down, the material box 1 will be pushed. In order to avoid large-area contact between the second substrate 5 and the side of the material box, that is, to reduce the pushing friction resistance, the receiving block 53 is used as the contact point to reduce the contact area.

[0034] The above are merely preferred embodiments of the present invention and do not limit the scope of the patent. Any equivalent structural or procedural transformations made based on the description and drawings of the present invention, or direct or indirect applications in other related technical fields, are similarly included within the scope of patent protection of the present invention.
