DETAILED DESCRIPTION

[0025] The following will clearly and completely describe the concept, specific structure and technical effects of the present invention in combination with the embodiments and drawings, so as to fully understand the purpose, characteristics and effects of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, other embodiments obtained by technical personnel in this field without creative work are within the scope of protection of the present invention. In addition, all the connection / connection relationships involved in the patent do not refer to the direct connection of components, but refer to the fact that a better connection structure can be formed by adding or reducing connection accessories according to the specific implementation situation. The various technical features in the creation of the present invention can be combined interactively without conflicting with each other.

[0026] Reference Figures 1 to 4 An example of the present invention provides a semiconductor device correction mechanism, including a bracket 100, a mounting base 200 set on the bracket 100, a plurality of clamping jaws 300 movably connected to the mounting base 200, a push rod 400 slidably connected to the bracket 100, and a driving member 500 for driving the push rod 400 to rise or fall. The push rod 400 is vertically arranged, the mounting base 200 is provided with a first through hole for accommodating the push rod 400 to pass through, and the plurality of clamping jaws 300 are distributed in a ring array along the axis of the push rod 400, one end of the clamping jaw 300 is a clamping end 321, and the other end of the clamping jaw 300 is provided with an inclined surface 311, and a clamping space is formed between the plurality of clamping ends 321.

[0027] During operation, the driving member 500 drives the top rod 400 to rise, and the top of the top rod 400 abuts against several inclined surfaces 311. During the rising process of the top rod 400, the several clamping claws 300 are pushed to open outward. Then, the transplanting mechanism (not shown in the figure) transplants the LED semiconductor device to the top of the product correction mechanism. It should be noted that the LED lamp beads are located at the bottom of the circuit board, so that the LED lamp beads on the circuit board are placed in the clamping space. Then, the driving member 500 drives the top rod 400 to descend, and the several clamping claws 300 lose the support of the top rod 400 and close together inward, so that the clamping parts of the several clamping claws 300 respectively limit the LED lamp beads. Therefore, the LED lamp beads can be accurately corrected to the set position to ensure the consistency of the position of the LED lamp beads. Moreover, it can reduce the labor intensity of workers and improve production efficiency.

[0028] In some preferred embodiments, the clamping jaw 300 includes an L-shaped swing arm 310 and a clamping finger 320, the clamping finger 320 is arranged at the top end of the L-shaped swing arm 310, and the inclined surface 311 is arranged at the other end of the L-shaped swing arm 310. The L-shaped swing arm 310 is rotatably connected to the mounting base 200. During the process of the driving member 500 driving the push rod 400 to rise, the top of the push rod 400 pushes the inclined surface 311 to drive several L-shaped swing arms 310 to swing outward at the same time, and several L-shaped swing arms 310 respectively drive several clamping fingers 320 to open outward to form a clamping space. Specifically, the top of the push rod 400 is hemispherical, so that the top of the push rod 400 can be evenly stressed when it contacts the inclined surface 311.

[0029] Furthermore, the mounting seat 200 is provided with a plurality of limiting grooves 210, which are distributed in a ring array along the axis of the first through hole, and a plurality of L-shaped swing arms 310 are respectively located in the plurality of limiting grooves 210, and the limiting grooves 210 limit the three sides of the L-shaped swing arms 310.

[0030] It can be understood that, on the one hand, the two sides of the limit groove 210 can limit the two sides of the L-shaped swing arm 310 to prevent the L-shaped swing arm 310 from shifting during the swinging process. On the other hand, the limit groove 210 can limit the inward side of the L-shaped swing arm 310 to ensure the position of several L-shaped swing arms 310 when they are closed, so that several clamping fingers 320 can just contact the LED lamp beads when they are closed, preventing the several clamping fingers 320 from closing too much and causing damage to the LED lamp beads, and at the same time preventing the several clamping fingers 320 from closing too little and failing to contact the LED lamp beads, resulting in correction failure.

[0031] In some preferred embodiments, an adjustment assembly 600 is provided on the L-shaped swing arm 310, and the adjustment assembly 600 includes an adjusting bolt 610 and a nut 620. The adjusting bolt 610 is threadedly connected to the nut 620, and the nut 620 is fixed on one side of the L-shaped swing arm 310. A second through hole is provided in the L-shaped swing arm 310 for accommodating the screw rod of the adjusting bolt 610, and an abutment block 220 is provided in the limiting groove 210, and the abutment block 220 is used to abut one end of the adjusting bolt 610.

[0032] On the one hand, when several L-shaped swing arms 310 are closed, one end of the adjusting bolt 610 connected to the swing arm abuts against the abutment block 220 in the limiting groove 210. When the abutment block 220 is worn, the abutment block 220 can be directly replaced, thereby preventing the adjusting bolt 610 from directly abutting against the limiting groove 210, avoiding wear of the mounting seat 200, and reducing maintenance costs.

[0033] On the other hand, by turning the adjusting bolt 610, the extension length of the adjusting bolt 610 can be adjusted, thereby adjusting the closing range of the plurality of L-shaped swing arms 310, and thus being able to adapt to LED lamp beads of different sizes.

[0034] In some preferred embodiments, the driving member 500 includes a motor 510 and an eccentric wheel 520 arranged on the main shaft of the motor 510. The motor 510 is installed on the bracket 100, and the eccentric wheel 520 is located directly below the top rod 400. The motor 510 drives the eccentric wheel 520 to rotate, and the eccentric wheel 520 drives the top rod 400 to rise and fall back and forth, thereby ensuring the rising amplitude of the top rod 400, and further, controlling the outward opening amplitude of several L-shaped swing arms 310.

[0035] Furthermore, the bottom end of the top rod 400 is rotatably connected to the follower wheel 410, and the outer circle of the follower wheel 410 abuts against the outer circle of the eccentric wheel 520. When the motor 510 drives the eccentric wheel 520 to rotate, the eccentric wheel 520 drives the follower wheel 410 to rotate. At the same time, the height of the top end of the eccentric wheel 520 will change accordingly. The eccentric wheel 520 drives the follower wheel 410 and the top rod 400 to rise and fall together, thereby improving the smoothness of the rise of the top rod 400.

[0036] In some preferred embodiments, a guide seat 700 is provided on the bracket 100, a guide hole 710 is provided in the guide seat 700, the mounting seat 200 is installed on the guide seat 700, the guide hole 710 is slidably matched with the top rod 400, and the guide hole 710 can guide the top rod 400, thereby improving the stability of the top rod 400 when it is raised or lowered.

[0037] Furthermore, the push rod 400 is fixedly connected to a follower block 420, which is located directly below the guide seat 700. A spring 430 is provided between the follower block 420 and the guide seat 700. The push rod 400 is located in the inner ring of the spring 430, and the follower block 420 and the guide seat 700 limit the two ends of the spring 430 respectively.

[0038] It can be understood that when the motor 510 drives the eccentric wheel 520 to rotate so that the height of the top of the eccentric wheel 520 increases, the eccentric wheel 520 drives the push rod 400 to rise, and the push rod 400 drives the follower block 420 to rise together, and the guide seat 700 is fixed on the bracket 100. The follower block 420 will compress the spring 430 during the rising process. When the motor 510 drives the eccentric wheel 520 to continue to rotate, the height of the top of the eccentric wheel 520 decreases, and the spring 430 uses its own elastic force on the follower block 420, causing the follower block 420 and the push rod 400 to decrease together so that the follower wheel 410 is always pressed on the eccentric wheel 520, thereby ensuring the normal opening and closing of the clamping jaws 300.

[0039] Furthermore, two guide rods 440 are provided on the bracket 100. The two guide rods 440 are vertically arranged. The follower block 420 is symmetrically provided with two linear bearings 450 along the center. The two linear bearings 450 are respectively sleeved on the two guide rods 440. The follower block 420 can move along the length direction of the guide rod 440, thereby further improving the stability of the top rod 400 during movement.

[0040] In some preferred embodiments, a photoelectric sensing sheet 810 is provided on the axial side of the eccentric wheel 520, and a photoelectric sensing groove 820 is provided on the bracket 100. The photoelectric sensing groove 820 is located on the radial side of the eccentric wheel 520, and the photoelectric sensing sheet 810 corresponds to the photoelectric sensing groove 820.

[0041] Specifically, when the motor 510 drives the eccentric wheel 520 to rotate so that the height of the top end of the eccentric wheel 520 drops to the lowest point, the eccentric wheel 520 drives the photoelectric sensing sheet 810 to rotate into the photoelectric sensing slot 820. After the photoelectric sensing slot 820 senses the photoelectric sensing sheet 810, it transmits the signal to the motor 510, and the motor 510 stops working. At this time, several jaws 300 close to correct the position of the LED lamp beads.

These equivalent modifications or substitutions are all included in the scope defined by the claims of this application.
