Existing board collectors typically use grippers to ensure stability when grabbing large panels, securing the four sides of the panel for better gripping.

Those skilled in the art will understand the specific meanings of the above terms in the embodiments of the present invention based on specific circumstances.

[0026] In one embodiment of the present invention, Figures 1 to 6 As shown, a top roller positioning mechanism of a plate collecting machine is provided, including a manipulator 20, a feeding belt 1 and two fixed frames 2, the manipulator 20 is provided with a frame 201 and clamping jaws 202 symmetrically distributed on both sides of the frame 201, and a gap is provided between each clamping jaw 202, a plurality of driving rods 11 are arranged front and back on the feeding belt 1, the two fixed frames 2 are symmetrically arranged at the bottom of the feeding belt 1, the fixed frames 2 are provided with a transverse driving member 3 and a clapping member 4, the transverse driving member 3 is used to realize the left and right movement of the clapping member 4 For right transverse movement, the fixing frame 2 is further provided with a driving cylinder 21, and the output shaft of the driving cylinder 21 is connected to a lifting platform 22. A number of beams 231 are arranged front and back on the lifting platform 22, and a number of push rods 24 are provided on the beams 231. There are avoidance spaces 232 between each of the beams 231, and there are avoidance spaces 232 between each of the push rods 24. Each avoidance space 232 corresponds to each of the clamps 202 respectively, and a pulley 242 is provided on the top of each of the push rods 24 for realizing left and right transverse movement of the plate.

[0027] Furthermore, each of the two transverse drive members 3 includes a drive motor 31, a transmission wheel 32, and a transmission belt 33. The two drive motors 31 are mounted on one of the fixed frames 2. The two transmission wheels 32 are rotatably connected to the other fixed frame 2. The drive motors 31 and the transmission wheels 32 are coupled via a transmission belt 33. Each transmission belt 33 is provided with a movable block 331, each of which is fixedly connected to the bottom of one of the clapper members 4. A slide bar 25 is connected between the two fixed frames 2. Slide blocks 251 are slidably connected to the left and right ends of the slide bar 25. The bottom of the slide block 251 is fixedly connected to the top of the movable block 331. Specifically, when the clapper member 4 is driven, the drive motor 31 drives the transmission belt 33, which in turn drives the movable block 331 to move horizontally, thereby achieving horizontal and horizontal movement of the clapper member 4. The slide bar 25 also provides good support, maintaining a horizontal and linear position during clapper member 4 movement, thus achieving a better movement effect.

[0028] Furthermore, the clapper member 4 includes a connecting strip 41, a connecting rod 42, and a plurality of comb teeth 43. The bottom end of the connecting rod 42 is fixedly connected to the slider 251, and the top end extends upward through the loading belt 1 and is fixedly connected to the connecting strip 41. The comb teeth 43 are evenly distributed at the bottom of the connecting strip 41, and the comb teeth 43 move horizontally in the gaps between the drive rods 11. Specifically, during the process of arranging the boards, the clapper member 4 is driven to move horizontally by the transverse drive member 3. During this process, the comb teeth 43 contact both sides of the boards, reducing the contact area between the boards and the clapper member 4, reducing friction, and preventing damage to the circuit boards during the clapping process.

[0029] Furthermore, the fixed frame 2 comprises a vertical portion and a horizontal portion connected to each other. The driving cylinder 21 is mounted at the bottom of the horizontal portion. The output shaft of the driving cylinder 21 extends upward through the horizontal portion and is fixedly connected to the lifting platform 22. The lifting platform 22 has a lifting rod 221 extending downward, and the bottom of the lifting rod 221 is slidably connected to the horizontal portion. Specifically, the driving cylinder 21 drives the lifting platform 22 upward, and the installation of the lifting rod 221 during this process can better maintain the stability of the lifting platform 22 during the raising and lowering process.

[0030] Furthermore, the crossbeam 231 is an L-shaped structure, and the bottom of the crossbeam 231 is limitedly engaged with the driving rod 11.

[0031] Furthermore, a frame 10 is provided at the input end of the feeding belt 1 , and a code reader 101 is provided on the top of the frame 10 .

[0032] Furthermore, a side frame 102 is extended to one side of the frame 10 , and an electrostatic rod 103 is installed on the side frame 102 .

[0033] Working principle: When in use, the plate is placed through the input end of the feeding belt 1, and the plate information is scanned and recorded by the code reader 101. At the same time, the static electricity of the plate surface is eliminated by the electrostatic rod 103. After the plate is transported to the specified position by the feeding belt 1, the lifting platform 22 is lifted by the driving cylinder 21, thereby lifting the plate. The transverse driving parts 3 on both sides of the feeding belt 1 respectively drive a plate-beating part 4 to move to both sides of the plate and position and level the plate. In this process, the plate is pushed by the plate-beating part 4, and the bottom of the plate rolls with the pulley 242 to reduce the friction of the bottom of the plate. The frame 201 is then driven by the manipulator 20 to move to the top of the plate. According to the placement of the plate, The posture of the frame 201 is determined by the formula. When the panel enters the loading belt 1 with the long side as the starting end, the frame 201 rotates to an angle that enables the clamping claws 202 to clamp the long side of the panel, and the long side of the panel is clamped by the clamping claws 202. When clamping, the clamping claws 202 go deep into the avoidance spaces between the various top rods 241 to avoid the air, and clamp with the bottom of the panel; when the panel enters the loading belt 1 with the short side as the starting end, the frame 201 rotates to an angle that enables the clamping claws 202 to clamp the long side of the panel, and the long side of the panel is clamped by the clamping claws 202. When clamping, the clamping claws 202 go deep into the avoidance spaces between the various cross beams 231 to avoid the air, and clamp with the bottom of the panel, thereby achieving a multi-angle avoidance effect.

[0034] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
