Description

Technical Field

[0001] The utility model relates to a conveying mechanism, in particular to a clamping type precise positioning conveying mechanism. Background Art

[0002] For glass laser drilling machines, it is necessary to transport the glass sheet to the drilling device through a conveying mechanism, align the drilling position of the glass sheet with the laser head of the drilling device, and then perform the drilling operation. At present, when conveying glass sheets, a clamp is usually used to clamp the glass sheet. In order to align the glass sheet with the laser head more accurately, the glass sheet is fine-tuned when the glass sheet is transported to the position of the laser head. For example, Chinese patent ZL202323002228.8 discloses a photovoltaic glass laser drilling clamp, which can adjust the position of the glass sheet after clamping the glass sheet, which is conducive to the drilling process of the glass sheet. However, clamping the glass sheet at the laser head and performing fine-tuning requires very high control accuracy of the clamp, and the laser drilling machine has limited equipment space at its laser head, which also has a certain degree of limitation on the range of motion of the clamp. Summary of the invention

[0003] The problem to be solved by the utility model is to provide a clamping type precise positioning and conveying mechanism, which can accurately control the glass sheet during the conveying process, so that the punching position of the glass sheet can be accurately positioned and aligned with the punching laser head. The technical solution adopted is as follows:

[0004] A clamping type precise positioning conveying mechanism, comprising a frame, a conveyor belt mechanism and a conveying drive mechanism, wherein the conveyor belt mechanism and the conveying drive mechanism are both arranged on the frame, and the conveyor belt mechanism is drivingly connected to the power output end of the conveying drive mechanism, characterized in that: the conveyor belt mechanism comprises a first conveyor belt mechanism and a second conveyor belt mechanism, and the clamping type precise positioning conveying mechanism also comprises a conveying adjustment mechanism, a front clamping assembly and a rear clamping assembly; the conveying adjustment mechanism is arranged on the frame, the first conveyor belt mechanism and the second conveyor belt mechanism are installed side by side on the adjustment end of the conveying adjustment mechanism, and the conveying adjustment mechanism is used to drive the first conveyor belt mechanism and the second conveyor belt mechanism to move toward or away from each other in the lateral direction; the front clamping assembly comprises two front clamping members, and the two front clamping members are respectively arranged at the front ends of the first conveyor belt mechanism and the second conveyor belt mechanism; the rear clamping assembly comprises two rear clamping members, and the two rear clamping members are respectively arranged at the rear parts of the first conveyor belt mechanism and the second conveyor belt mechanism.

[0005] The above-mentioned first conveyor belt mechanism and second conveyor belt mechanism are used to convey the glass sheets from front to back, and the conveying driving mechanism drives the first conveyor belt mechanism and the second conveyor belt mechanism to move synchronously; when conveying the glass sheets, the glass sheets are placed horizontally, and the two sides of the glass sheets are respectively placed flat on the first conveyor belt mechanism and the second conveyor belt mechanism.

[0006] The above-mentioned conveying adjustment mechanism is used to drive the first conveyor belt mechanism and the second conveyor belt mechanism to move toward or away from each other. When moving toward each other, the two sides of the glass sheet placed flat between the first conveyor belt mechanism and the second conveyor belt mechanism are clamped and limited. When moving away from each other, the glass sheet is slightly loosened, which can drive the glass sheet to move forward and backward and fine-tune the front and rear position of the glass sheet, so that the punching position of the glass sheet can be accurately positioned and aligned with the punching laser head.

[0007] The above-mentioned front clamping assembly is used to initially clamp and fix the glass sheet when the glass sheet enters the conveyor belt mechanism; the above-mentioned rear clamping assembly is arranged at the rear of the first conveyor belt mechanism and the second conveyor belt mechanism, corresponding to the position of the punching laser head, and is used to position, clamp and fix the glass sheet when the glass sheet reaches the punching position.

[0008] With the cooperation of the first conveyor belt mechanism, the second conveyor belt mechanism and the conveying adjustment mechanism, when the glass plate is loosened, the glass plate can be transported forward and backward, and when the glass plate is tightened again, it can be repositioned, and multiple holes can be continuously punched in the front and back directions of a piece of glass.

[0009] As a preferred embodiment of the present utility model, the first conveyor belt mechanism and the second conveyor belt mechanism both include a conveying base, a conveyor belt, a driving wheel and a driven wheel; the conveying base can be movably mounted on the adjusting end of the conveying adjustment mechanism, the driving wheel and the driven wheel can be rotatably mounted on the conveying base, the driving wheel and the driven wheel tension the conveyor belt, and the driving wheel is transmission-connected to the power output end of the conveying drive mechanism.

[0010] As a further preferred embodiment of the present invention, the two front clamping members are relatively arranged on the conveying bases of the first conveyor belt mechanism and the second conveyor belt mechanism and are located on the outside of the corresponding conveyor belts, and the distance between the two front clamping members gradually decreases along the conveying direction of the first conveyor belt mechanism and the second conveyor belt mechanism; the two rear clamping members are relatively arranged on the conveying bases of the first conveyor belt mechanism and the second conveyor belt mechanism and are located on the outside of the corresponding conveyor belts, and the distance between the two rear clamping members is equal along the conveying direction of the first conveyor belt mechanism and the second conveyor belt mechanism.

[0011] The distance between the two front clamping members arranged at the front end of the conveying mechanism gradually decreases along the conveying direction of the first conveyor belt mechanism and the second conveyor belt mechanism, so that the entrance of the entire conveying mechanism forms a trumpet shape, which facilitates the glass sheet to gradually enter the conveying mechanism under the limit of the two front clamping members and smoothly lie flat on the first conveyor belt mechanism and the second conveyor belt mechanism. The distance between the two rear clamping members arranged at the front end of the conveying mechanism is equal along the conveying direction of the first conveyor belt mechanism and the second conveyor belt mechanism, which facilitates fine adjustment of the position of the glass sheet when punching.

[0012] In order to stably clamp the glass sheet, the clamping surfaces of the front clamping member and the rear clamping member are preferably rough planes.

[0013] As a further preferred embodiment of the present invention, the front clamping member and the rear clamping member are both mounted on the corresponding conveying base through a clamping fine-tuning mechanism. The front clamping member and the rear clamping member are both fine-tuned through the clamping fine-tuning mechanism. On the one hand, it can adapt to glass sheets of different shapes, and on the other hand, it is also convenient for fine-tuning and centering.

[0014] As a still further preferred embodiment of the present invention, the clamping fine-tuning mechanism includes a fine-tuning screw, a fine-tuning through hole opened in the corresponding front clamping member or rear clamping member, and a fine-tuning screw hole opened in the corresponding conveying base; the fine-tuning screw hole is horizontally elongated, and the fine-tuning screw passes through the corresponding fine-tuning through hole and is locked in the corresponding fine-tuning screw hole. By adjusting the locking position of the fine-tuning screw in the fine-tuning screw hole, the horizontal mounting position of the front clamping member or the rear clamping member on the conveying base is adjusted.

[0015] As a further preferred embodiment of the present invention, the conveying adjustment mechanism includes an adjustment motor, an adjustment lead screw, two adjustment nuts, at least one adjustment guide rod, and at least two guide sleeves; the adjustment motor is arranged on the frame, the adjustment lead screw and the adjustment guide rod are arranged in parallel on the frame along the conveying direction of the conveyor belt, one end of the adjustment lead screw is in transmission connection with the output shaft of the adjustment motor, and the other end is rotatably mounted on the frame; the adjustment lead screw is provided with a positive thread section and a reverse thread section with opposite directions, the two adjustment nuts are respectively mounted on the conveying bases of the first conveyor belt mechanism and the second conveyor belt mechanism, and the two adjustment nuts are respectively sleeved on the positive thread section and the reverse thread section; the two guide sleeves are respectively mounted on the conveying bases of the first conveyor belt mechanism and the second conveyor belt mechanism, and the two guide sleeves are both sleeved on the adjustment guide rod. The adjustment motor is used to drive the adjustment lead screw to rotate, and is guided by the guide sleeve and the adjustment guide rod. Under the combined action of the positive thread section, the reverse thread section and the adjustment thread, the first conveyor belt mechanism and the second conveyor belt mechanism move towards or away from each other.

[0016] As a further preferred embodiment of the present utility model, the conveying drive mechanism includes a drive motor, a main transmission shaft, a first driving main gear, a second driving main gear, a first driven transmission gear, and a second driven transmission gear; the drive motor is arranged on the frame, one end of the main transmission shaft is in transmission connection with the output shaft of the drive motor, and the other end is rotatably installed on the frame. The length direction of the main transmission shaft corresponds to the moving direction of the first conveyor belt mechanism and the second conveyor belt mechanism; the first driving main gear and the second driving main gear are both fixedly sleeved on the main transmission shaft. The first driving main gear corresponds to the position of the first conveyor belt mechanism, and the second driving main gear corresponds to the position of the second conveyor belt mechanism; the first driven transmission gear meshes with the first driving main gear and the first driven transmission gear is in transmission connection with the driving wheel of the first conveyor belt mechanism. The second driven transmission gear meshes with the second driving main gear and the second driven transmission gear is in transmission connection with the driving wheel of the second conveyor belt mechanism. The length of the first driving main gear is greater than the length of the first driven transmission gear, and the length of the second driving main gear is greater than the length of the second driven transmission gear.

[0017] When the conveying drive mechanism works, the drive motor drives the main transmission shaft to rotate, driving the first driving main gear and the second driving main gear to rotate simultaneously and synchronously. Through the meshing of the first driven transmission gear with the first driving main gear and the meshing of the second driven transmission gear with the second driving main gear, the driving wheels of the first conveyor belt mechanism and the second conveyor belt mechanism rotate synchronously, thereby driving the first conveyor belt mechanism and the second conveyor belt mechanism to move synchronously in the same direction. When the conveying adjustment mechanism drives the first conveyor belt mechanism and the second conveyor belt mechanism to move towards or away from each other, the first driven transmission gear moves synchronously on the first driving main gear along with the translation of the first conveyor belt mechanism, and the second driven transmission gear moves synchronously on the second driving main gear along with the translation of the second conveyor belt mechanism, ensuring that the first conveyor belt mechanism and the second conveyor belt mechanism still maintain synchronous operation during translation to convey the glass sheets.

[0018] Both the above-mentioned conveying adjustment mechanism and the conveying drive mechanism are driven by servo motors, with low noise during the working process, and no vibration will be generated, which will not affect the glass sheets during conveying and positioning, ensuring that the glass sheets can be accurately aligned with the punching laser head.

[0019] Compared with the prior art, the present utility model has the following advantages:

[0020] The clamping type precise positioning and conveying mechanism of the present utility model conveys glass sheets from front to back through the first conveyor belt mechanism and the second conveyor belt mechanism, and then drives the first conveyor belt mechanism and the second conveyor belt mechanism to move towards or away from each other in the transverse direction through the conveying adjustment mechanism. When moving towards each other, the two sides of the glass sheet placed between the first conveyor belt mechanism and the second conveyor belt mechanism are clamped and limited for fixation. When moving away from each other, the glass sheet is slightly loosened, and it can drive the glass sheet to move back and forth and finely adjust the front and back positions of the glass sheet. On the one hand, it can accurately position the punching position of the glass sheet to align with the punching laser head, and on the other hand, it can also continuously punch multiple holes in the front and back directions of a glass sheet.

[0028] AsFigure 1 As shown in the figure, the front clamping assembly includes two front clamping members 4. The two front clamping members 4 are relatively arranged at the front ends of the conveying bases 601 of the first conveyor belt mechanism 6A and the second conveyor belt mechanism 6B and are located outside the corresponding conveyor belts 602. The distance between the two front clamping members 4 gradually decreases along the conveying direction of the first conveyor belt mechanism 6A and the second conveyor belt mechanism 6B; the rear clamping assembly includes two rear clamping members 5. The two rear clamping members 5 are relatively arranged at the rear parts of the conveying bases 601 of the first conveyor belt mechanism 6A and the second conveyor belt mechanism 6B and are located outside the corresponding conveyor belts 602. The distance between the two rear clamping members 5 is equal along the conveying direction of the first conveyor belt mechanism 6A and the second conveyor belt mechanism 6B; in order to stably clamp the glass sheet, the clamping surfaces of the front clamping members 4 and the rear clamping members 5 are both rough planes; the front clamping members 4 and the rear clamping members 5 are both installed on the corresponding conveying bases 601 through clamping fine adjustment mechanisms 7.

[0029] The clamping type precise positioning conveying mechanism of the present utility model conveys the glass sheet from front to back through the first conveyor belt mechanism 6A and the second conveyor belt mechanism 6B, and then drives the first conveyor belt mechanism 6A and the second conveyor belt mechanism 6B to move towards or away from each other in the horizontal direction through the conveying adjustment mechanism 3. When moving towards each other, the two sides of the glass sheet placed flat between the first conveyor belt mechanism 6A and the second conveyor belt mechanism 6B are clamped and limited and fixed. When moving away from each other, the glass sheet is slightly loosened, and it can drive the glass sheet to move back and forth and finely adjust the front and back positions of the glass sheet.

When moving away from each other, the glass sheet is slightly loosened, enabling the glass sheet to move back and forth and finely adjust the front and back positions of the glass sheet, so that the drilling position of the glass sheet can be accurately positioned and aligned with the drilling laser head. Additionally, with the cooperation of the first conveyor belt mechanism 6A, the second conveyor belt mechanism 6B, and the conveying adjustment mechanism 3, when the glass plate is loosened, the glass plate can be conveyed back and forth, and when the glass plate is clamped again, it can be repositioned, allowing multiple holes to be continuously drilled in the front and back directions of a single glass sheet.

[0031] Specifically, when the conveying drive mechanism 2 is operating, the drive motor drives the rotation of the main drive shaft 201, driving the first drive main gear 202 and the second drive main gear 203 to rotate simultaneously and synchronously. Through the meshing of the first drive secondary gear 204 with the first drive main gear 202 and the meshing of the second drive secondary gear 205 with the second drive main gear 203, the driving wheels of the first conveyor belt mechanism 6A and the second conveyor belt mechanism 6B rotate synchronously, thereby driving the first conveyor belt mechanism 6A and the second conveyor belt mechanism 6B to move synchronously in the same direction. When the conveying adjustment mechanism 3 drives the first conveyor belt mechanism 6A and the second conveyor belt mechanism 6B to move towards or away from each other, the first drive secondary gear 204 translates synchronously on the first drive main gear 202 as the first conveyor belt mechanism 6A translates, and the second drive secondary gear 205 translates synchronously on the second drive main gear 203 as the second conveyor belt mechanism 6B translates, ensuring that the first conveyor belt mechanism 6A and the second conveyor belt mechanism 6B remain synchronized during translation while conveying the glass sheet.

[0032] Specifically, the distance between the two front clamping members 4 provided at the front end of the conveying mechanism gradually decreases along the conveying direction of the first conveyor belt mechanism 6A and the second conveyor belt mechanism 6B, forming a trumpet shape at the entrance of the entire conveying mechanism, facilitating the glass sheet to gradually enter the conveying mechanism under the limitation of the two front clamping members 4 and be placed flat on the first conveyor belt mechanism 6A and the second conveyor belt mechanism 6B. The distance between the two rear clamping members 5 provided at the front end of the conveying mechanism is equal along the conveying direction of the first conveyor belt mechanism 6A and the second conveyor belt mechanism 6B, facilitating fine adjustment of the position of the glass sheet during drilling.
