Description

Technical Field

[0001] The invention relates to the technical field of glass processing, in particular to a large-size glass peripheral polishing machine. Background Art

[0002] Glass is an amorphous inorganic non-metallic material. It is generally made from a variety of inorganic minerals (such as quartz sand, borax, boric acid, barite, barium carbonate, limestone, feldspar, soda ash, etc.) as the main raw materials, and a small amount of auxiliary raw materials.

[0003] After searching, the patent document with authorization announcement number CN214445476U discloses a horizontal vehicle-mounted glass polishing machine, which includes a base, a drainage groove, an X-axis ball screw drive mechanism, an X-axis slider of the X-axis ball screw drive mechanism, an X-axis slide, a servo motor assembly and a guide rail along the Y-axis direction are provided on the X-axis slide, a Y-axis slider is provided on the guide rail, a Y-axis slide is provided on the Y-axis slider, and an eccentric wheel is provided at the bottom of the Y-axis slide; the output shaft of the servo motor assembly is connected to the eccentric wheel to drive the Y-axis slide to move back and forth along the Y-axis; two groups of independently controlled lifting and lowering Z-axis ball screw drive mechanisms are arranged side by side on one side of the Y-axis slide, and polishing wheel mechanisms are provided on the Z-axis sliders of the two groups of Z-axis ball screw drive mechanisms.

[0004] When the above-mentioned polishing machine is in use, a jig is installed on the Y-axis slide, and the vehicle glass to be polished is placed on the jig and fixed by vacuum adsorption. During processing, the X-axis slide reciprocates left and right, and the Y-axis slide swings back and forth through the eccentric wheel. The two brush wheels are driven by the Z-axis ball screw drive mechanism. Through the set program, the two brush wheels are pressed against the glass to polish according to the trajectory of the curvature of the glass. However, the use of the above-mentioned polishing machine can only polish the surface of the glass, and cannot polish the edge of the glass. Even if the position of the jig is changed so that the edge of the glass on the jig is adaptively contacted and fitted with the brush wheel, due to the layout and structural setting of this polishing machine, after the glass is polished, there will be more serious polishing marks on the edge of the glass, which will affect subsequent processing.

[0022] At the same time, the present invention also proposes a control method applied to the above-mentioned large-size glass peripheral polishing machine, and the control method comprises the following steps:

[0023] Step 1: Place the glass on the bearing plate and use the top pressure piece to drive the connecting plate belt and the side pressure plate to move vertically downward until the top of the glass is pressed. At this time, the side pressure plate will apply a vertical downward pressing force to the glass. The magnitude of the pressing force can be preset according to the type of glass;

[0024] Step 2: Using the second motor to drive the polishing wheel to rotate, and at the same time, using the driving member to drive the polishing wheel to reciprocate along its axis direction;

[0025] Step 3: Use the fourth motor to drive the base to move until the polishing wheel on the base contacts the edge of the glass;

[0026] Step 4: According to the direction of the cutting force applied by the polishing wheel to the edge of the glass, the input instruction corresponding to the rotation direction of the output shaft of the first motor at this time is transmitted to the controller, and the controller acts on the power source after processing, so that the power source relies on the crank connecting rod to apply force to the side pressure plate; if the direction of the cutting force applied by the polishing wheel to the edge of the glass is vertically downward, the power source relies on the crank connecting rod to apply a vertically upward lifting force to the side pressure plate, and the vertically upward lifting force is the same as the vertically downward cutting force, so as to ensure that the vertical downward force applied to the glass is always a preset size; if the direction of the cutting force applied by the polishing wheel to the edge of the glass is vertically upward, the power source relies on the crank connecting rod to apply a vertically downward dragging force to the side pressure plate, and the vertically downward dragging force is the same as the vertically upward cutting force, so as to ensure that the vertical downward force applied to the glass is always a preset size.

[0027] Compared with the prior art, the present invention has the following beneficial effects:

[0028] 1. Through the arrangement of the base, the moving base and the polishing wheel, the polishing wheel can rotate on the moving base, and the moving base can drive the polishing wheel to slide back and forth on the base, that is, the motion trajectory of the polishing wheel is composed of its own rotation and reciprocating motion in the vertical direction. This kind of motion of the polishing wheel can perform vertical reciprocating polishing on the edge of the glass, with good polishing effect and uniform polishing, which effectively solves the problem of heavy polishing marks left on the edge of the glass during the early processing, and improves the aesthetics of the glass after processing;

[0029] 2. Through the setting of the connecting plate and the side pressure plate, when in use, the side pressure plate can not only exert a downward pressure on the glass with a larger contact area, but also adjust the downward pressure on the glass to a preset value. The preset pressure force can ensure that the overall force on the glass is within the specified range, which is convenient for polishing;

[0030] 3. By setting a preset value during the polishing process, the preset value not only ensures that the glass will not be damaged by excessive pressure, but also ensures that the glass will not vibrate due to a pressure lower than the preset value;

[0031] 4. Through the setting of the adjusting member, the adjusting member is used to apply a vertical upward lifting action tendency or a vertical downward dragging action tendency to the side pressure plate to adapt to the reciprocating motion of the moving seat; specifically, when the polishing wheel applies a vertical downward cutting action force to the edge of the glass, the adjusting member is used to apply a vertical upward lifting action tendency to the side pressure plate; when the polishing wheel applies a vertical upward cutting action force to the edge of the glass, the adjusting member is used to apply a vertical downward dragging action tendency to the side pressure plate; combining the above two situations, the adjusting member can offset the cutting action force applied by the reciprocating motion of the polishing wheel on the glass, so that the entire glass is always subjected to the preset pressing action force;

[0032] 5. By including a controller and a power source in the adjusting member, when the first motor is used to drive the polishing wheel to rotate, the signal instruction corresponding to the corresponding direction of the output shaft of the first motor can be transmitted to the controller as input, so that the controller controls the power source to generate a corresponding lifting or dragging action trend. The present invention automatically changes the action trend of the power source on the glass according to the different movement directions of the polishing wheel, and the design is ingenious.

[0033] 6. Through the setting of the crank-connecting rod structure, in the working state, the power source will exert a lifting or dragging action on the second auxiliary arm, which is transmitted to the first auxiliary arm through the main arm and finally acts on the side pressure plate. The lifting or dragging action has a vertical upward or downward component. The component in this direction can offset the cutting force exerted by the light wheel on the edge of the glass, ensuring that the overall force of the glass is controlled within the preset value;

[0034] 7. By setting the lever arm from the first auxiliary arm to the upper fulcrum of the main arm smaller than the lever arm from the second auxiliary arm to the upper fulcrum of the main arm, under this design, the lifting or dragging action tendency at the second auxiliary arm will be amplified to the first auxiliary arm, and then the action on the side pressure plate can be maximized, that is, the power source set only needs to have a small energy action tendency, so that there are more types of power sources to choose from and the setting can be compact;

[0035] 8. By setting the power source as an electromagnet, under the signal instructions corresponding to the two directions of the output shaft of the first motor, the two groups of electromagnets will have a movement tendency of mutual attraction or repulsion, and the two groups of electromagnets will work together to cooperate with the crank connecting rod to perform a lifting or dragging action tendency;

[0036] 9. Through the arrangement of the second motor and the assembly cylinder, the output shaft of the second motor is rotatably connected to the top end of the polishing wheel, and the piston rod of the assembly cylinder is rotatably connected to the bottom end of the polishing wheel. Both connections are detachable, which is convenient for disassembly and assembly of the polishing wheel;

[0037] 10. Through the setting of the side cylinder and the flip block, the existence of the flip block can, on the one hand, expand the outer ring pressing area of ​​the side pressure plate, so that when the glass size is larger than the size of the supporting plate, the whole composed of the side pressure plate and the flip block can perform good surface contact pressing on the edge of the glass; on the other hand, through the pressure of the flip block on the glass, the edge of the glass is firmly pressed, at this time, the speed of the vertical upward movement of the polishing wheel can be accelerated, thereby improving the polishing efficiency.

DETAILED DESCRIPTION

[0052] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0053] Embodiment 1:

[0054] like Figure 1-Figure 6 As shown, a large-size glass peripheral polishing machine includes a machine tool 1, a fixture for clamping the surface of the glass a, and a polishing assembly for polishing the edge of the glass a, as shown in FIG. Figure 3As shown, the fixture is arranged in the middle of the machine tool 1. When in use, the surface of the glass a to be polished is first clamped and fixed by the fixture, and the fixture can drive the glass a to rotate horizontally, and then the edge of the glass a is polished by the polishing assembly. Specifically, the polishing assembly includes a base 2, a moving seat 3, a polishing wheel 4 and a driving member. The base 2 is arranged on the machine tool 1, and the moving seat 3 is slidably installed on the side of the base 2 facing the fixture. The polishing wheel 4 is rotatably arranged on the moving seat 3 and arranged in the vertical direction. The driving member is fixedly arranged on the base 2, and the driving member is used to drive the moving seat 3 to reciprocate on the base 2 along the rotation axis direction of the polishing wheel 4, so as to Figure 3 From the perspective of the polishing wheel 4, the reciprocating motion is vertical reciprocating motion. Figure 1 As shown, the whole composed of the base 2, the movable seat 3 and the polishing wheel 4 can be set into two groups, and the two groups of the whole are relatively locally arranged, and the clamp is located between the two groups of the whole. The use of the two groups of the whole can improve the polishing efficiency of the glass a.

[0055] Under the design structure of the above polishing assembly, after the glass a is clamped and fixed by the clamp, the polishing wheel 4 is driven to rotate. At the same time, the driving member is used to drive the movable seat 3 to reciprocate. The reciprocating movement of the movable seat 3 can drive the polishing wheel 4 to rotate and reciprocate at the same time, and then drive the base 2 to move toward the edge of the glass a until the polishing wheel 4 contacts the edge of the glass a to achieve polishing. Figure 1-Figure 3 as well as Figure 7 Taking the case shown as an example, the rotation axis direction of the polishing wheel 4 is arranged along the vertical direction, and then the reciprocating motion of the polishing wheel 4 is along the vertical direction, that is, the motion trajectory of the polishing wheel 4 is: the combined motion of the self-rotation motion and the reciprocating motion along the vertical direction. The present invention utilizes this motion of the polishing wheel 4 to perform vertical up and down reciprocating polishing on the edge of the glass a, with good polishing effect and uniform polishing, which effectively solves the problem of heavy polishing marks left at the edge of the glass a during the early processing.

[0056] In order to ensure that the base 2 can drive the polishing wheel 4 to smoothly approach the edge of the glass a, in this embodiment, a guide rail 13 is fixedly provided on the machine tool 1, and the base 2 is slidably installed on the guide rail 13. At the same time, a fourth motor (not shown in the figure) is provided on the machine tool 1, and a threaded rod (not shown in the figure) is fixedly provided on the output shaft of the fourth motor. The base 2 is threadedly sleeved on the threaded rod, and then the fourth motor can be used to drive the threaded rod to rotate, that is, the base 2 can be driven to move on the guide rail 13, so as to achieve the approach or distance between the polishing wheel 4 and the edge of the glass a. At the same time, Figure 1 and Figure 4As shown, during the polishing process, in order to improve the polishing effect of glass a, the present invention also includes two groups of nozzle assemblies 14 arranged on the movable seat 3, and the two groups of nozzle assemblies 14 are respectively located on both sides of the polishing wheel 4, and the nozzle assemblies 14 can spray polishing liquid or clean water to the polishing area between the polishing wheel 4 and the edge of glass a.

[0057] Regarding the setting of the above-mentioned driving member, the driving member includes a first motor 5 fixedly set on the base 2, and the output shaft of the first motor 5 is fixedly provided with a reciprocating screw 6 arranged along the vertical direction, a connecting block 7 is threadedly sleeved on the reciprocating screw 6, and the connecting block 7 is fixedly connected to the moving seat 3, and then the first motor 5 can be used to drive the reciprocating screw 6 to rotate, thereby realizing the sliding of the moving seat 3 on the base 2.

[0058] like Figure 1-Figure 2 As shown, for the setting of the above-mentioned middle clamp, the clamp includes a third motor 10 arranged on the machine tool 1, a supporting plate 11 arranged on the output shaft of the third motor 10, and a pressing piece arranged on the machine tool 1 and located above the supporting plate 11. When in use, the glass a is placed on the supporting plate 11, and then the top of the glass a is pressed by the pressing piece. The pressing piece can be a telescopic rod or an oil cylinder, etc., preferably a cylinder. When the pressing piece is set as a pressing cylinder 12, a plunger is rotatably arranged at the piston rod of the pressing cylinder 12. The plunger on the piston rod of the pressing cylinder 12 can stably clamp the glass a, and the plunger can rotate relative to the pressing cylinder 12. Then, the supporting plate 11, the glass a and the plunger in the clamped state can form a whole. The third motor 10 can drive the whole composed of the above three to perform a corresponding rotation action. Combined with the polishing action of the polishing wheel 4, the edge of the glass a among the three can be circumferentially polished.

[0059] like Figure 5 As shown, in order to realize the installation and rotation of the polishing wheel 4 on the moving seat 3, the second motor 8 and the assembly cylinder 9 can be fixedly arranged on the top and bottom of the moving seat 3, respectively, and the piston rod of the assembly cylinder 9 is coaxially arranged with the output shaft of the second motor 8, the top of the polishing wheel 4 is fixedly connected with the output shaft of the second motor 8, and the bottom of the polishing wheel 4 is rotatably abutted with the piston rod of the assembly cylinder 9. Then, the second motor 8 can be started to drive the polishing wheel 4 to rotate, and the polishing work at the edge of the glass a can be realized by coordinating the vertical up and down movement of the polishing wheel 4. When the polishing wheel 4 is subsequently disassembled, it is only necessary to move the piston rod of the assembly cylinder 9 downward to release the abutment with the bottom end of the polishing wheel 4, and then release the connection between the top of the polishing wheel 4 and the output shaft of the second motor 8.

[0060] like Figure 4As shown, in order to prevent foreign objects such as dust from the external environment from interfering with the operation of the polishing wheel 4, the present invention can also be used to cover the second motor 8 on the movable seat 3. Furthermore, in order to ensure the stable installation of the above-mentioned top pressure cylinder 12, a fixed bracket 16 can be separately arranged on the machine tool 1, and the top pressure cylinder 12 is fixedly installed on the fixed bracket 16.

[0061] The base 2, the moving seat 3 and the polishing wheel 4 are regarded as a whole, wherein the base 2 is used as a carrier of the moving seat 3, and the moving seat 3 is used as a carrier of the polishing wheel 4 and the second motor 8. Figure 1-Figure 3 As an example, the three components are fixed on the machine tool 1, which is intended to ensure that the polishing wheel 4 is arranged vertically, so that the polishing wheel 4 in this direction can perform vertical polishing on the edge of the glass a in a horizontal position. This state can be obtained by Figure 7 To express, Figure 7 The b line in the figure represents the direction of the rotation axis of the polishing wheel 4, and the b line is arranged in the vertical direction. The c line represents the direction of the edge of the glass a, and the c line is arranged in the horizontal direction.

[0062] Embodiment 2:

[0063] like Figure 8-Figure 9 As shown, in the above-mentioned embodiment 1, the design for clamping and limiting the glass a is that the glass a is pressed against the supporting plate 11 by a plunger rotatably arranged on the top-pressing cylinder 12, and then the supporting plate 11, the glass a and the plunger form a rotatable whole. However, if the glass a is pressed against the supporting plate 11 solely by the plunger on the top-pressing cylinder 12, since the contact area between the plunger and the glass a is small, during the rotation process, only the middle position of the glass a is subjected to the downward pressing force, and the side position thereof is not subjected to any downward pressing force. When the whole composed of the supporting plate 11, the glass a and the plunger is driven to rotate and is in contact with the polishing wheel 4 for processing, a small vibration may be generated at the edge of the glass a, thereby affecting the polishing effect. Based on this, this embodiment adds a connecting plate 17 and two side pressure plates 18 on the basis of any of the above embodiments; specifically, the connecting plate 17 is slidably arranged on the machine tool 1 along the vertical direction, the connecting plate 17 is located above the bearing plate 11 and is driven to move by the top pressure member, the top pressure member in this embodiment is the top pressure cylinder 12 in the first embodiment, the connecting plate 17 is rotatably arranged at the bottom end of the piston rod of the top pressure cylinder 12, and the two side pressure plates 18 are respectively hingedly arranged on both sides of the connecting plate 17, such as Figure 8 As shown, the connecting plate 17 and the pressure plates 18 on both sides are arranged in a U shape as a whole.

[0064] Based on the above design, when the present embodiment is used, the glass a is first placed on the carrier plate 11, and then the top pressure cylinder 12 is used to drive the connecting plate 17 and the two side pressure plates 18 to move downward until the two side pressure plates 18 contact the top of the glass a. At this time, the glass a is stably pressed as a whole by relying on the large-area contact between the side pressure plates 18 and the top of the glass a and the left-right layout design of the two side pressure plates 18. Then the piston rod of the top pressure cylinder 12 is driven to slowly apply force downward, and the downward force acts on the glass a through the two side pressure plates 18 until the downward pressure force on the glass a as a whole reaches a preset value, so that the glass a is stably pressed on the carrier plate 11. In the subsequent polishing process, the glass a under the preset pressure force will not vibrate or be damaged. It should be noted that the setting of the hinged structure between the side pressure plate 18 and the connecting plate 17 here can meet the requirement that the connecting plate 17 drives the side pressure plate 18 to move downward and contact the glass a.

[0065] Embodiment three:

[0066] In combination with the reciprocating motion characteristic of the polishing wheel 4 in the above embodiment, Figure 7 Taking the polishing wheel 4 shown as reciprocating along the vertical direction as an example, when the polishing wheel 4 moves vertically upward, the polishing wheel 4 will apply a vertically upward force to the edge of the glass a. Since the side pressure plate 18 has applied a preset vertically downward pressing force to the glass a as a whole in the above-mentioned second embodiment, the vertically upward force applied by the polishing wheel 4 to the edge of the glass a will destroy the overall force balance of the glass a, so that the vertical downward pressing force applied to the glass a as a whole is less than the preset value. During the polishing process, the edge of the glass a may still vibrate. When the polishing wheel 4 moves vertically downward, the polishing wheel 4 will apply a vertically downward force to the edge of the glass a. The generation of this force will also destroy the overall force balance of the glass a, so that the vertical downward pressing force applied to the glass a as a whole is greater than the preset value, which may then cause damage to the glass a.

[0067] Based on this, this embodiment adds an adjustment member based on the design of the above-mentioned clamp, and the adjustment member is used to apply a vertical upward lifting force or a vertical downward dragging force to the side pressure plate 18 to adapt to the reciprocating motion of the moving seat 3. Figure 7Taking the polishing wheel 4 shown as performing reciprocating motion in the vertical direction as an example, when the polishing wheel 4 moves vertically downward, that is, the movable seat 3 drives the polishing wheel 4 to apply a vertically downward cutting force to the edge of the glass a, the adjusting member is used to apply a vertically upward lifting force to the side pressure plate 18, and the lifting force can offset the vertically downward cutting force applied by the polishing wheel 4 to the edge of the glass a, so that the vertically downward pressing force applied to the glass a as a whole tends to or is equal to the preset value. When the polishing wheel 4 moves vertically upward, that is, the movable seat 3 drives the polishing wheel 4 to apply a vertically upward cutting force to the edge of the glass a, the adjusting member is used to apply a vertically downward dragging force to the side pressure plate 18, and the dragging force can offset the vertically upward cutting force applied by the polishing wheel 4 to the edge of the glass a, so that the vertically downward pressing force applied to the glass a as a whole tends to or is equal to the preset value.

[0068] Specifically, the regulating member includes a controller (not shown in the figure), two groups of crank connecting rods 19 relatively arranged on the connecting plate 17, and two groups of power sources 20 arranged on the connecting plate 17. The two groups of power sources 20 are located between the two groups of crank connecting rods 19. The separated ends of the two groups of crank connecting rods 19 are respectively hinged to the inner sides of the pressure plates 18 on both sides, and the close ends of the two groups of crank connecting rods 19 are respectively hinged to the execution ends of the two groups of power sources 20. The driving member and the two groups of power sources 20 are electrically connected to the controller, and the two groups of power sources 20 are controlled by the controller. It should be noted that the electrical connection between the driving member and the controller in this embodiment is intended to be used to transmit different working states of the driving member to the controller as corresponding input instructions. The driving member is equivalent to the first motor 5 for explanation below.

[0069] In this embodiment, the adjustment member is set and the two working states of the adjustment member are utilized to adapt the reciprocating motion of the polishing wheel 4, so that the combined pressure force on the glass a as a whole approaches or is equal to a preset value, thereby ensuring the overall stability of the glass a and providing good protection for the glass a, which is beneficial to the polishing process.

[0070] Still Figure 7Taking the polishing wheel 4 shown as performing reciprocating motion in the vertical direction as an example, the first motor 5 is used to drive the polishing wheel 4 to perform reciprocating motion in the vertical direction. When the polishing wheel 4 moves vertically downward, that is, the polishing wheel 4 applies a vertically downward cutting force to the edge of the glass a, the signal instruction corresponding to the rotation direction of the output shaft of the first motor 5 at this time is input into the controller. After being processed by the controller, the controller drives the power source 20 to work, so that the power source 20 applies a vertically upward lifting force to the side pressure plate 18 through the crank connecting rod 19; when the polishing wheel 4 moves vertically upward, that is, the polishing wheel 4 applies a vertically upward cutting force to the edge of the glass a, the signal instruction corresponding to the rotation direction of the output shaft of the first motor 5 at this time is input into the controller. After being processed by the controller, the controller drives the power source 20 to work, so that the power source 20 applies a vertically downward dragging force to the side pressure plate 18 through the crank connecting rod 19.

[0071] It should be noted that the specific structural arrangement of the crank connecting rod 19 and the power source 20 can be conventional technical means in the prior art, as long as the cooperation between the two can achieve the lifting or dragging force on the side pressure plate 18 .

[0072] Embodiment 4:

[0073] This embodiment specifically introduces the preferred structure of the crank connecting rod 19 and the power source 20 in the third embodiment:

[0074] (i) a crank connecting rod 19, wherein the crank connecting rod 19 comprises a main arm 1901 rotatably disposed on the connecting plate 17, and a first auxiliary arm 1902 and a second auxiliary arm 1903 are respectively hingedly disposed at both ends of the main arm 1901, and the first auxiliary arm 1902 is hingedly connected to the inner side of the side pressure plate 18, and the second auxiliary arm 1903 is hingedly connected to the execution end of the power source 20;

[0075] (1) Combination Fig. 9 When the polishing wheel 4 moves vertically downward, the signal instruction corresponding to the rotation direction of the output shaft of the first motor 5 drives the two groups of power sources 20 to move away from each other through the controller. At this time, the power source 20 will exert a lifting action trend on the second auxiliary arm 1903, and the lifting action trend is transmitted to the first auxiliary arm 1902 through the main arm 1901, and finally acts on the side pressure plate 18. The lifting action trend has a vertical upward component, and the action trend of the vertical upward component can offset the vertical downward cutting force exerted by the polishing wheel 4 on the edge of the glass a;

[0076] (2) Combination Fig.10When the polishing wheel 4 moves vertically upward, the signal instruction corresponding to the rotation direction of the output shaft of the first motor 5 drives the two groups of power sources 20 to move closer to each other through the controller. At this time, the power source 20 will exert a dragging action trend on the second auxiliary arm 1903, and the dragging action trend is transmitted to the first auxiliary arm 1902 through the main arm 1901, and finally acts on the side pressure plate 18. The dragging action trend has a vertical downward component, and the action trend of the vertical downward component can offset the vertical upward cutting force exerted by the polishing wheel 4 on the edge of the glass a;

[0077] (3) Combination Figure 9-10 On the basis of the above-mentioned crank connecting rod 19 structure setting, in order to ensure that the lifting or dragging action tendency generated by the second auxiliary arm 1903 is amplified and transmitted to the first auxiliary arm 1902, and finally acts on the side pressure plate 18, the force arm from the first auxiliary arm 1902 to the main arm 1901 fulcrum can be set to be smaller than the force arm from the second auxiliary arm 1903 to the main arm 1901 fulcrum. It can be known from the principle of lever that when the force arm from the first auxiliary arm 1902 to the main arm 1901 fulcrum is smaller than the force arm from the second auxiliary arm 1903 to the main arm 1901 fulcrum, the lifting or dragging action tendency at the second auxiliary arm 1903 will be amplified to the first auxiliary arm 1902, and then can be maximized to act on the side pressure plate 18, and only a small power source 20 needs to be set later to meet the use requirements.

[0078] (ii) Power source 20. Based on the above-mentioned crank connecting rod 19 structure setting, the power source 20 is preferably set as an electromagnet. Two groups of electromagnets work together. Then, when the output shaft of the first motor 5 has two rotation directions, the signal instruction corresponding to the rotation direction is transmitted to the controller, and then the controller makes the two groups of electromagnets have a movement tendency of mutual adsorption or repulsion to cooperate with the crank connecting rod 19 to lift or drag. Of course, in some possible embodiments, the two groups of power sources 20 can also be set as cylinders or oil cylinders. When the two groups of power sources 20 are set as double-headed cylinders, when the double-headed cylinders receive the corresponding signal instructions from the controller, the piston rods at both ends of the double-headed cylinders can simultaneously generate an extension or contraction movement tendency to offset the cutting force generated by the polishing wheel 4 on the edge of the glass a. Of course, the power source 20 can also be set as a conventional single-headed cylinder. Two groups of power sources 20 need to be set with two groups of single-headed cylinders correspondingly. The two groups of single-headed cylinders work independently without interfering with each other.

[0079] It should be noted that the input-output logic relationship between the signal instructions, controller and power source 20 corresponding to the different rotation directions of the output shaft of the first motor 5 is a conventional technical setting in the prior art, and the composition of this logic relationship is not limited in this article, as long as the corresponding rotation direction of the output shaft of the first motor 5 can control the power source 20 to produce a corresponding movement trend under the control of the controller. For example, the positive voltage signal generated when the output shaft of the first motor 5 rotates forward acts on the power source 20 through the controller, so that the power source 20 performs a corresponding movement trend; the negative voltage signal generated when the output shaft of the first motor 5 rotates reversely acts on the power source 20 through the controller, so that the power source 20 performs a movement trend opposite to the aforementioned movement trend.

[0080] Furthermore, the controller in this article can be any suitable computing device, such as a personal computer, a server, a PLC controller, a single-chip microcomputer, etc., or it can be an integration of computer devices. The controller has functions such as receiving information and sending control commands. The controller can control the power source 20 to perform corresponding actions through wired communication or wireless communication to offset the cutting force applied by the polishing wheel 4 to the edge of the glass a.

[0081] Embodiment five:

[0082] like Figure 11-Figure 12 As shown, on the basis of the above-mentioned embodiment 2, the clamp in this embodiment also includes a side cylinder 21 arranged on the outer side of the side pressure plate 18 and a flip block 22 hingedly arranged on the side of the bottom end of the side pressure plate 18, the flip block 22 is hinged to the piston rod of the side cylinder 21, and the flip block 22 is located between the polishing wheel 4 and the side pressure plate 18, the side cylinder 21 is used to drive the flip block 22 to press against or away from the glass a to adapt to the reciprocating motion of the polishing wheel 4.

[0083] Specifically, when the moving seat 3 drives the polishing wheel 4 to apply a vertical downward cutting force to the edge of the glass a, the positive voltage signal corresponding to the downward rotation of the output shaft of the first motor 5 is transmitted to the controller, and the controller acts on the side cylinder 21, so that the side cylinder 21 drives the flip block 22 away from the glass a to prevent the flip block 22 from exerting a pressing force on the glass a and causing damage to the glass a. This state can be Fig.11 To indicate; when the moving seat 3 drives the polishing wheel 4 to apply a vertical upward cutting force to the edge of the glass a, the negative voltage signal corresponding to the downward rotation of the output shaft of the first motor 5 is transmitted to the controller, and the controller acts on the side cylinder 21, so that the side cylinder 21 drives the flip block 22 to press against the glass a. This state can be represented by Fig.12 To express.

[0084] In this embodiment, a side cylinder 21 and a flip block 22 are provided. When the side cylinder 21 presses the flip block 22 against the glass a, the existence of the flip block 22 can, on the one hand, expand the outer ring pressing area of ​​the side pressure plate 18, so that when the size of the glass a is larger than the size of the supporting plate 11, the whole composed of the side pressure plate 18 and the flip block 22 can perform good surface contact pressing on the edge of the glass a; on the other hand, the flip block 22 presses the glass a so that the edge of the glass a is firmly pressed, and at this time the speed of the vertical upward movement of the polishing wheel 4 can be accelerated, thereby improving the polishing efficiency.

[0085] Embodiment six:

[0086] The present invention also proposes a control method for a large-size glass peripheral polishing machine, which comprises the following steps:

[0087] Step 1: Place glass a on the carrier plate 11 and use the top pressure piece to drive the connecting plate 17 and the side pressure plate 18 to move vertically downward until the top of glass a is pressed. At this time, the side pressure plate 18 will apply a vertical downward pressing force to glass a. The magnitude of the pressing force can be preset according to the type of glass a;

[0088] Step 2: Using the second motor 8 to drive the polishing wheel 4 to rotate, at the same time, using the driving member to drive the polishing wheel 4 to reciprocate along its axis direction;

[0089] Step 3: Use the fourth motor to drive the base 2 to move until the polishing wheel 4 on the base 2 contacts the edge of the glass a;

[0090] Step 4: According to the direction of the cutting force applied by the polishing wheel 4 to the edge of the glass a, the input command corresponding to the rotation direction of the output shaft of the first motor 5 is transmitted to the controller, and the controller acts on the power source 20 after processing, so that the power source 20 applies force to the side pressure plate 18 by means of the crank connecting rod 19; if the direction of the cutting force applied by the polishing wheel 4 to the edge of the glass a is vertically downward, the power source 20 applies a vertically upward lifting force to the side pressure plate 18 by means of the crank connecting rod 19, and the vertically upward lifting force is the same as the vertically downward cutting force, so as to ensure that the vertical downward force applied to the glass a is always a preset size; if the direction of the cutting force applied by the polishing wheel 4 to the edge of the glass a is vertically upward, the power source 20 applies a vertically downward dragging force to the side pressure plate 18 by means of the crank connecting rod 19, and the vertically downward dragging force is the same as the vertically upward cutting force, so as to ensure that the vertical downward force applied to the glass a is always a preset size.

All equivalent changes and improvements made within the scope of the present invention should still fall within the scope of the patent coverage of the present invention.
