Description

Technical Field

[0001] The utility model relates to the technical field of glass grinding, in particular to an edge grinding device and an edge grinding machine. Background Art

[0002] The edge grinding process is the first process in the deep processing of solar glass panels and backplane glass. The micro cracks and sharp angles on the edges of the blank glass sheets cut into different shapes and sizes are ground, polished, and chamfered to achieve the required specifications and dimensions. In the existing glass edge grinding process, the grinding wheel groove is prone to damage and wear due to long-term use, so the grinding wheel needs to be replaced frequently.

[0003] In existing edge grinding devices, after the grinding wheel is replaced, it is often necessary to adjust the grinding wheel position up and down when the groove is completed. For example, the person who replaces the grinding wheel usually needs to clamp a piece of glass between the grinding wheel groups and then manually calibrate it by hand. This method is not only time-consuming, but also has a greater safety risk. In addition, due to the inaccuracy of manual calibration, it may also cause quality defects in glass edge grinding.

[0036] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0039] In existing edge grinding devices, after the grinding wheel is replaced, it is often necessary to adjust the grinding wheel position up and down when the groove is completed. For example, the person who replaces the grinding wheel usually needs to clamp a piece of glass between the grinding wheel groups and then manually calibrate it by hand. This method is not only time-consuming, but also has a greater safety risk. In addition, due to the inaccuracy of manual calibration, it may also cause quality defects in glass edge grinding.

[0040] The utility model provides an edge grinding device.

[0041] See also Figure 2 In one embodiment of the present invention, the edge grinding device 100 is used for an edge grinding process of a target workpiece, and the edge grinding device 100 includes:

[0042] A lifting mechanism 1 is arranged above the target workpiece;

[0043] The rotating mechanism 2 is drivingly connected to the lifting mechanism 1 so as to move along a first direction under the driving of the lifting mechanism 1;

[0044] A grinding wheel 3 is detachably disposed on a side of the rotating mechanism 2 facing the target workpiece, and the rotating mechanism 2 drives the grinding wheel 3 to rotate; and

[0045] The positioning mechanism 4 includes a scale plate 41 and a pointer 42. The scale plate 41 is spaced apart on one side of the rotating mechanism 2, and scale lines arranged along a first direction are arranged on the scale plate 41; the pointer 42 is arranged on the side of the rotating mechanism 2 facing the scale plate 41 and is arranged corresponding to the scale plate 41 to indicate the scale line corresponding to when the grinding wheel 3 is in the edge grinding state.

[0046] In the technical solution of the utility model, the rotating mechanism 2 is connected to the grinding wheel 3 and can drive the grinding wheel 3 to rotate, so as to facilitate the edge grinding of the target workpiece. The lifting mechanism 1 is located above the target workpiece, and is mainly used to control the vertical distance between the grinding wheel 3 and the target workpiece, so as to adjust the distance according to the target workpiece of different thicknesses. In addition, the operation of replacing the grinding wheel 3 can also be assisted by the up and down movement of the lifting mechanism 1. When the grinding wheel 3 is in the edge grinding state, the position of the grinding wheel 3 in the first direction can be indicated by the scale on the scale plate 41 pointed to by the pointer 42 at this time; when replacing the grinding wheel 3, the grinding wheel 3 needs to be raised first, the old grinding wheel 3 is removed and replaced with a new grinding wheel 3, and then the grinding wheel 3 is lowered to the original position by comparing the original scale. This solution does not require manual calibration of the groove when replacing the grinding wheel 3, ensuring that the grinding wheel 3 is accurately reset to the initial edge grinding state, which is conducive to shortening the replacement time and improving the replacement efficiency of the grinding wheel 3.

[0047] Specifically, the rotating mechanism 2 can be a servo motor, a gear transmission mechanism, etc., as long as it can drive the grinding wheel 3 to rotate. It should be noted that the positioning mechanism 4 can also be other structures for indicating the height, such as a plurality of indicating grooves can be provided on the scale plate 41, and the end of the pointer 42 can be inserted into the indicating groove to limit the position of the grinding wheel 3. The scale plate 41 can be a micrometer, or a triangle ruler, etc., as long as it is a ruler with a scale.

[0048] In an embodiment of the utility model, the pointer 42 is rotatably provided on the rotating mechanism 2. In order not to affect the edging work of the grinding wheel 3 on the target workpiece, when there is no need to replace the grinding wheel 3, the pointer 42 can be rotated to a position in contact with the outer surface of the rotating mechanism 2 to avoid affecting the edging and conveying process of the target workpiece.

[0049] In the embodiments of the present invention, please refer to Figure 4 and Figure 5The rotation angle range of the pointer 42 is 0°-90°. When the pointer 42 is in the rotation state of 0°, the pointer 42 is set parallel to the scale plate 41 to prevent the pointer 42 from protruding outside the rotating mechanism 2 and affecting the edge grinding process. When the pointer 42 is in the rotation state of 90°, the pointer 42 is set vertically to the scale plate 41, that is, a 90° right angle is formed between the pointer 42 and the scale plate 41. In this state, the direction of the pointer 42 can directly reflect the position of the grinding wheel 3 during the edge grinding process. The operator can adjust the position of the grinding wheel 3 in time according to the position of the pointer 42 to ensure the dimensional accuracy of the edge grinding. In addition, the rotation angle range of the pointer 42 is 0°-90°, which also limits the rotation range of the pointer 42 and avoids damage caused by excessive rotation.

[0050] In the embodiments of the present invention, please refer to Figure 4 and Figure 5 The positioning mechanism 4 further includes a rotating hinge 43, which connects the pointer 42 and the rotating mechanism 2. The rotating hinge 43 is usually composed of two metal sheets, which are connected by an axis so that they can rotate relative to each other. In the positioning mechanism 4, one end is connected to the pointer 42, and the other end is connected to the rotating mechanism 2. Such a design allows the pointer 42 to rotate within an angle range of 0° to 90° under the drive of the rotating mechanism 2.

[0051] In the embodiments of the present invention, please refer to Figures 2 to 5 The outer diameter of the pointer 42 decreases from the end away from the scale plate 41 to the end close to the scale plate 41. This design makes the pointer 42 sharp at the end close to the scale plate 41, which is more convenient for indicating and aligning the scale line on the scale plate 41. The pointer 42 with a decreasing outer diameter can be, for example, a tapered shaft, as long as it has a sharp end and can accurately indicate the scale on the scale plate 41.

[0052] In another embodiment of the present invention, please refer to Figure 4 and Figure 5 , the longitudinal section of the pointer 42 is a triangle, that is, when the pointer 42 is rotated 90° and set perpendicular to the scale plate 41, the longitudinal section of the pointer 42 in the direction perpendicular to the scale plate 41 is a triangle, and at this time one of the angles of the triangle is set opposite to the scale.

[0053] In the embodiments of the present invention, please refer to Figure 6The grinding wheel 3 is provided with a plurality of grinding wheel grooves 31, and the plurality of grinding wheel grooves 31 are arranged at intervals on the outer peripheral surface of the grinding wheel 3. In order to increase the service life of the grinding wheel 3, a plurality of grinding wheel grooves 31 may be provided on the outer wall of each grinding wheel 3. When one of the grinding wheel grooves 31 is damaged and cannot be used, a new grinding wheel groove 31 may be replaced for continued use. Before replacement, the distance between the new grinding wheel groove 31 and the old grinding wheel groove 31 may be recorded first, and then the rotating mechanism 2 may be raised or lowered by the same distance according to the distance, so that the new grinding wheel groove 31 can face the target workpiece. During the process of replacing the grinding wheel groove 31, the specific distance of the rise or fall of the grinding wheel 3 may be marked by the scale plate 41, and there is no need to manually measure the distance with the help of other objects, thereby improving the replacement efficiency.

[0054] In an embodiment of the present utility model, the lifting mechanism 1 comprises:

[0055] A support column having a cavity therein; and

[0056] The threaded rod is disposed in the cavity and is threadedly connected to the support column. The threaded rod is fixedly connected to the rotating mechanism 2.

[0057] Specifically, the lifting mechanism 1 includes two main parts: a support column and a threaded rod. The support column is the main part of the lifting mechanism 1, which is usually a column with a cavity inside. The function of this cavity is to accommodate the threaded rod and provide guidance for the movement of the threaded rod. The threaded rod is another important part of the lifting mechanism 1. It is arranged in the cavity inside the support column and is threadedly connected to the support column. The function of the threaded rod is to transmit rotational motion and convert it into linear motion, thereby driving the rotating mechanism 2 to lift and lower in the first direction to facilitate the replacement of the grinding wheel 3. It should be pointed out that the thread of the threaded rod needs to be precisely processed to ensure the smooth and precise lifting and lowering motion.

[0058] The utility model also provides an edge grinding machine, which comprises:

[0059] frame;

[0060] A conveying device, used for conveying a target workpiece; and

[0061] The edge grinding device 100 is disposed above the conveying device at intervals to grind the target workpiece. The edge grinding device 100 is the edge grinding device 100 described in any of the above embodiments.

[0062] Specifically, the specific structure of the edge grinding device 100 refers to the above-mentioned embodiment. Since the edge grinding machine adopts all the technical solutions of all the above-mentioned embodiments, it at least has all the beneficial effects brought by the technical solutions of the above-mentioned embodiments, which will not be repeated here. Among them, the conveying device is used to convey the target workpiece to the edge grinding device 100. After it is ready to be conveyed to the bottom of the edge grinding device 100, the grinding wheel 3 performs the edge grinding process. It should be noted that a plurality of edge grinding devices 100 can be provided in the edge grinding machine. When it is necessary to edge a target workpiece with a long length such as a glass plate, a plurality of edge grinding devices 100 can edge the same glass plate at the same time, or each edge grinding device 100 can edge a glass plate separately, thereby improving the edge grinding efficiency.

[0063] In the embodiments of the present invention, please refer to Figure 1 and Figure 3 The edge grinding machine also includes a protective cover 200, which is arranged above the conveying device. Its main function is to protect the safety of operators and equipment. During the edge grinding process, glass fragments and grinding chips may splash, and these fragments and grinding chips may cause harm to the operator or damage the equipment. The existence of the protective cover 200 can effectively prevent these problems from occurring and improve work safety. In addition, the protective cover 200 can also prevent external impurities and dust from entering the edge grinding area, affecting the quality and accuracy of edge grinding. It can play a certain shielding role and keep the edge grinding area clean and stable. A scale plate 41 is provided on the side of the protective cover 200 facing the rotating mechanism 2 to facilitate observation and operation by the operator. The operator can adjust the position and parameters of the grinding wheel 3 in the edge grinding device 100 through the scale on the scale plate 41 to achieve the desired edge grinding effect.

[0064] In an embodiment of the utility model, the edge grinding machine further includes a recycling device, which is arranged below the edge grinding device 100. The recycling device is usually composed of one or more collecting containers, and its main function is to collect and recycle glass fragments and grinding chips generated during the edge grinding process. During the edge grinding process, the edge of the glass will be ground to generate some fragments and grinding chips, which need to be cleaned up in time to ensure the quality and safety of the edge grinding. The recycling device may also include some filtering and separation devices for separating the grinding chips and glass fragments. In this way, the grinding chips can be better recycled and utilized, while reducing the impact on the environment.

[0065] The above description is only an exemplary embodiment of the present invention, and does not limit the patent scope of the present invention. All equivalent structural changes made by using the contents of the present invention specification and drawings under the technical concept of the present invention, or directly / indirectly applied in other related technical fields are included in the patent protection scope of the present invention.
