Description

Technical Field

[0001] This invention relates to the field of photovoltaic solar cell frame manufacturing, and more particularly to an automatic chamfering machine for frames. Background Technology

[0002] The frame of a photovoltaic solar cell is composed of multiple aluminum frame strips. To ensure the structural strength of the photovoltaic solar cell frame, both ends of the frame strips need to be chamfered, and then the chamfered ends of the frame strips are joined together. Most existing chamfering devices are semi-manual. Because the frame vibrates too much when chamfering both ends of the frame at the same time, the chamfering quality is not high. Therefore, it is necessary to chamfer one end of the frame strip first, and then manually flip the frame strip to chamfer the other end. This results in the low degree of automation and chamfering efficiency of existing chamfering devices. Summary of the Invention

[0003] To overcome the above problems, the present invention provides an automatic beveling machine for borders. The technical solution adopted by the present invention to solve its technical problems is as follows: An automatic beveling machine for frames includes a conveyor belt. Frame strips fall horizontally onto the conveyor belt, perpendicular to its conveying direction. A first beveling device and a second beveling device are arranged opposite each other on both sides of the conveyor belt. Each beveling device includes a fixed base, and a base plate is provided on each fixed base. A support frame and a beveling mechanism are provided on each base plate.

The limit mechanisms on both the first and second beveling devices include a first limit component and a second limit component arranged side by side. The second limiting components on the second chamfering device are symmetrically arranged, and the second limiting components on the first chamfering device and the first limiting components on the second chamfering device are symmetrically arranged. The clamping mechanism includes a transfer component, on which a gripper cylinder is provided. The transfer component drives the gripper cylinder to clamp / release the frame strip from the lifting mechanism, and places both ends of the frame strip onto the first limiting components / second limiting components on the first chamfering device and the second chamfering device, respectively. Each chamfering mechanism includes an inclined linear sliding module, on which a chamfering motor is provided. The movable end of the chamfering motor is provided with a chamfering drill bit, and the chamfering drill bit only performs chamfering at the position of the first limiting component.

[0004] Furthermore, position sensors are installed on the side walls of the support frame to sense the position of the frame bars.

[0005] Furthermore, each fixed base is equipped with a slide rail and a lead screw. A handle is provided at one end of the lead screw, and a shuttle is sleeved on the lead screw. The shuttle moves along the lead screw as it rotates. The two sides of the base plate rest on the slide rail, and the bottom of the base plate is fixedly connected to the shuttle. Rotating the handle drives the lead screw to rotate, causing the shuttle to drive the base plate to slide along the slide rail.

[0006] Furthermore, the slide rail sidewall is provided with graduations, and the base plate side is provided with a scale to indicate the distance the base moves; both the base plate side and the slide rail are provided with several alignment holes, and screws are inserted into the alignment holes of the base plate and the slide rail to fix the base plate on the slide rail.

[0007] Furthermore, the lifting mechanism includes a lifting cylinder, and the movable end of the lifting cylinder is provided with an L-shaped lifting platform. The lifting cylinder drives the L-shaped lifting platform to rise / fall, and the L-shaped lifting platform lifts the frame strip away from / falls back onto the conveyor belt.

[0008] Furthermore, the side walls of the support frames of the first and second chamfering devices are equipped with alignment cylinders, and the movable end of the alignment cylinder is equipped with an alignment block. The alignment cylinder drives the alignment block to abut against the end of the frame strip so that the end of the frame strip is aligned in place.

[0009] Furthermore, the first limiting assembly includes a first limiting platform, a first side-pressing cylinder, a first downward-pressing cylinder, and a first tail-pressing cylinder fixed on the support frame. The end of the frame strip rests on the first limiting platform. The driving block of the first side-pressing cylinder presses the frame strip tightly onto the first limiting platform from the side. The driving block of the first upward-pressing cylinder presses the frame strip tightly onto the first limiting platform from above and below. The driving block of the first tail-pressing cylinder presses the end of the frame strip from the rear. The driving block of the first tail-pressing cylinder is provided with an avoidance angle.

[0010] Furthermore, the second limiting assembly includes a second limiting platform fixed on the support frame, a second side-pressing cylinder, a second downward-pressing cylinder, and a second tail-pressing cylinder. The end of the frame strip rests on the second limiting platform. The driving block of the second side-pressing cylinder presses the frame strip tightly onto the second limiting platform from the side. The second upward-pressing cylinder drives the pressing block to press the frame strip tightly onto the second limiting platform from above and below. The second tail-pressing cylinder drives the pressing block to press the end of the frame strip from the rear.

[0011] Furthermore, the support frame is equipped with an air nozzle, which is connected to a pressure valve via a pipe. The air nozzle faces the first and second limiting platforms to blow air onto the ends of the frame strip.

[0012] Furthermore, the transfer assembly includes a transfer motor, a tire, and a transverse guide rail mounted on a support frame. A transverse block is mounted on the transverse guide rail, with one end of the transverse block fixedly connected to the tire. A vertical cylinder is mounted on the transverse block, and a gripper cylinder is fixedly connected to the movable end of the vertical cylinder. The transfer motor drives the tire to rotate in both directions, and the tire drives the transverse block to move horizontally along the transverse guide rail. The vertical cylinder drives the gripper cylinder to move up and down, and the gripper cylinder clamps / releases the frame strip.

[0013] The beneficial effects of this invention are: The automatic beveling machine for frames includes a conveyor belt. Frame strips fall horizontally onto the conveyor belt, perpendicular to its conveying direction. A first beveling device and a second beveling device are arranged opposite each other on both sides of the conveyor belt. Both the first and second beveling devices include a fixed base, on which a base plate is provided. Each base plate is equipped with a support frame and a beveling mechanism. Lifting mechanisms are provided on both sides of the support frame to lift / drop the frame strips off / back onto the conveyor belt. Each support frame is equipped with a limit mechanism and a clamping mechanism. The limit mechanisms on both the first and second beveling devices include a first limit component and a second limit component arranged side-by-side. The second limiting components on the cornering device are symmetrically arranged, as are the second limiting components on the first chamfering device and the first limiting components on the second chamfering device. The clamping mechanism includes a transfer component, on which a gripper cylinder is mounted. The transfer component drives the gripper cylinder to clamp / release the frame strip from the lifting mechanism, and places both ends of the frame strip onto the first / second limiting components on the first and second chamfering devices, respectively. Each chamfering mechanism includes an inclined linear sliding module, on which a chamfering motor is mounted. A chamfering drill bit is mounted on the movable end of each chamfering motor, and the chamfering drill bit performs chamfering only at the position of the first limiting component. During operation... After the conveyor belt delivers the frame strip to its designated position, a lifting mechanism on one side raises the frame strip, causing it to detach from the conveyor belt. Then, a clamping mechanism picks up the frame strip and places both ends onto the first limiting component of the first chamfering device and the second limiting component of the second chamfering device, respectively. The limiting components clamp the frame strip. The chamfering mechanism on the first chamfering device chamfers one end of the frame strip on the first limiting component. After chamfering, the limiting component releases the frame strip, and the clamping mechanism picks up the chamfered frame strip and moves it parallel to the second limiting components on the first chamfering device and the second chamfering device, respectively. The limiting components clamp the frame strip, and the second chamfering mechanism... The chamfering mechanism on the corner device chamfers the other end of the frame strip on the first limiting component. After the chamfering is completed, the limiting component releases the frame strip, and the clamping and feeding mechanism clamps the frame strip with both ends chamfered and places it on the lifting mechanism on the other side. The lifting mechanism on the other side descends, causing the chamfered frame strip to fall onto the conveyor belt. The conveyor belt then sends the chamfered frame strip to the next work station. This device uses the first and second chamfering devices, which are set opposite to each other on both sides of the transmission belt, to chamfer both ends of the frame strip in stages. The whole process is automatic and highly automated. It only requires the clamping and feeding mechanism to translate and reposition the frame strip. There is no need to flip the frame strip, which improves the chamfering efficiency. Attached Figure Description

[0016] To better understand the purpose, structure, and function of this invention, the following detailed description of a specific embodiment of the "Automatic Beveling Machine for Borders" is provided in conjunction with the accompanying drawings.

[0017] See Figures 1-6In this embodiment, the automatic beveling machine for frames includes a conveyor belt (not shown). Frame strips 100 fall horizontally on the conveyor belt, perpendicular to its conveying direction. A first beveling device 200 and a second beveling device 201 are arranged facing each other on both sides of the conveyor belt. Both the first beveling device 200 and the second beveling device 201 include a fixed base 202. A base plate 203 is provided on each of their fixed bases 202, and a support frame 204 and a beveling mechanism 205 are provided on each of their base plates 203. Lifting mechanisms 206 are provided on both sides of the support frames 204 on the first beveling device 200 and the second beveling device 201. The lifting mechanisms 206 can lift / drop the frame strips 100 off / back onto the conveyor belt. A limiting mechanism 207 and a clamping mechanism 208 are provided on each of their support frames 204. The limiting mechanisms 207 on the first beveling device 200 and the second beveling device 201 each include a first limiting component 209 and a second limiting component 210 arranged side-by-side. The first limiting component 209 on the cornering device 200 and the second limiting component 210 on the second chamfering device 201 are symmetrically arranged; the second limiting component 210 on the first chamfering device 200 and the first limiting component 209 on the second chamfering device 201 are symmetrically arranged; the clamping mechanism 208 includes a transfer component 211, on which a gripper cylinder 212 is provided, and the transfer component 211 drives the gripper cylinder 212 to clamp / lower the frame strip 1 from the lifting mechanism 206. 00, and place both ends of the frame strip 100 onto the first limiting component 209 / second limiting component 210 on the first chamfering device 200 and the second chamfering device 201 respectively; the chamfering mechanism 205 includes an inclined linear sliding module 2051, and a chamfering motor 2052 is provided on the linear sliding module 2051. The movable end of the chamfering motor 2052 is provided with a chamfering drill bit 2053, and the chamfering drill bit 2053 only performs chamfering at the position of the first limiting component 209.

[0018] In summary, when the automatic frame chamfering machine is working, the conveyor belt passes from left to right between the first chamfering device 200 and the second chamfering device 201. After the conveyor belt transports the frame strip 100 to the left side of the first chamfering device 200 and the second chamfering device 201, the lifting mechanism 206 lifts the frame strip 100 to remove it from the conveyor belt. Then, the clamping mechanisms 208 on the first chamfering device 200 and the second chamfering device 201 work simultaneously, placing both ends of the frame strip 100 on the first limiting component 209 on the first chamfering device 200 and the second limiting component 210 on the second chamfering device 201, respectively. After the two limiting components clamp the frame strip 100, the chamfering mechanism 205 on the first chamfering device 200 operates to chamfer the end of the frame strip 100 on the first limiting component 209 on the first chamfering device 200. After the chamfering is completed, the limiting components are released, and the first chamfering device 200 and the second chamfering device 201 move away from the conveyor belt. The clamping and conveying mechanism 208 on the second chamfering device 201 operates simultaneously again, moving the frame strip 100, after one end has been chamfered, to the right and placing it on the second limiting component 210 on the first chamfering device 200 and the first limiting component 209 on the second chamfering device 201. After the two limiting components clamp the frame strip 100, the chamfering mechanism 205 on the second chamfering device 201 operates to chamfer the other end of the frame strip 100 on the first limiting component 209 on the second chamfering device 201. After the chamfering is completed, the limiting components are released, and the clamping and conveying mechanisms 208 on the first chamfering device 200 and the second chamfering device 201 together place the chamfered frame strip 100 on the lifting mechanism 206 on the right side of the first chamfering device 200 and the second chamfering device 201. The lifting mechanism 206 descends, dropping the chamfered frame strip 100 back onto the conveyor belt, which then transports the frame strip 100 to the next workstation. This device uses a first chamfering device 200 and a second chamfering device 201 arranged opposite to each other on both sides of the transmission belt to chamfer both ends of the frame strip 100 in sequence. The whole process is automatic and highly automated. It only requires the clamping mechanism 208 to translate and change the position of the frame strip 100. There is no need to flip the frame strip 100, which improves the chamfering efficiency.

[0019] See further Figure 1 , Figure 2 and Figure 6 In this embodiment, a position sensor 213 is provided on the left side wall of the support frame 204 to sense the position of the frame bar 100 and instruct the lifting mechanism 204 to lift the frame bar 100 off the conveyor belt.

The two sides of the base plate 203 rest on the slide rail 214, and the bottom of the base plate 203 is fixedly connected to the sliding shuttle 217. The handle 216 rotates to drive the lead screw 215 to rotate, so that the sliding shuttle 217 drives the base plate 203 to slide back and forth along the slide rail 214.
