Description

Technical Field

[0001] The invention belongs to the technical field of lighting appliance production, and in particular relates to an LED chip paving device. Background Art

[0002] During the production of LED tubes or bulbs, it is necessary to install the LED lamp beads in the tubes or bulbs according to the designed number. Usually, the installation operation is performed by a mechanical arm set on the assembly line to clamp the LED chip and place it in the installation position for subsequent processes to weld it on the circuit. In order to facilitate the clamping operation of the mechanical arm on the LED chip, the LED chip needs to be laid flat on a suitable platform to avoid affecting the application of the mechanical arm due to the stacking and staggering of the chips. The present invention provides a device that can efficiently lay LED chips flat. Summary of the invention

[0003] The present invention provides an LED chip tiling device to solve the problems in the above-mentioned background technology.

[0004] The technical problem solved by the present invention is achieved by adopting the following technical solutions:

The bracket extends upward from the four corners of the frame and folds inward to meet above the center of the frame. The bracket has a sleeve in the center, and the transmission part is hinged in the sleeve. The front side of the frame has a hinged platform, and the driving joint of the transmission part is hinged on the hinged platform. The working part includes a turntable, an axle seat and a first hinge hole. The bottom of the turntable has an axle seat, which is connected to the transmission joint of the transmission part and is located on the sleeve. The axle seat has a first hinge hole, and a pin is installed in the first hinge hole to connect the working part with the transmission part.

[0007] The transmission part includes a transmission joint, a transition joint, a shift fork, a compensation joint, a cross joint, a drive joint and a drive rod. The transmission joint includes a transmission shaft and a rocker arm. The transmission shaft is sleeved in the sleeve and connected to the shaft seat upward. A rocker arm is provided at the bottom of the transmission shaft, which is hinged to the transition joint, and the transition joint is hinged to the shift fork. The rod end of the shift fork has a pin hole, and the rod end of the shift fork is sleeved in the docking hole of the compensation joint. The front side of the compensation joint also has a pair of limiting grooves, and pins are installed from the limiting grooves to the pin holes to limit the shift fork laterally in the compensation joint and keep it from rotating around the rod end of the shift fork to compensate for the lateral rotation of the rod system. Another shift fork is installed at the other end of the compensation joint in the same way. The shift fork is hinged to the cross joint, and the other direction of the cross joint is hinged to the drive joint. A transverse shaft rod is provided at the bottom of the drive joint, and the shaft rod is hinged on the hinged platform of the base.

[0010] Furthermore, a pedal is provided at the rear end of the driving rod, and stepping on the pedal can drive the working part to rotate through the transmission part. As the turntable rotates, the LED chips are gradually laid flat under the action of centrifugal force.

[0011] The beneficial effects of the present invention are:

[0012] The present invention is used for the tiling operation of LED chips used in the production of LED lamps. After the LED chips are laid flat, they are convenient for a mechanical arm to clamp and install at a predetermined position. The present invention adopts a set of rod system structures to drive the turntable to rotate continuously. The rotating turntable relies on centrifugal force to gradually achieve the tiling operation of the LED chips. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0018] In order to facilitate the understanding of the present invention, the present invention will be described more fully below with reference to the relevant drawings. The preferred embodiments of the present invention are shown in the drawings. However, the present invention can be implemented in many different forms and is not limited to the embodiments described herein. On the contrary, the purpose of providing these embodiments is to make the disclosure of the present invention more thorough and comprehensive.

[0019] See also Figure 1-Figure 4 The LED chip paving device shown includes a base part 10 , a working part 20 and a transmission part 30 . The base part 10 supports the entire device on the ground, the working part 20 is installed on the base part 10 , and the transmission part 30 is connected to the base part 10 and the working part 20 .

[0020] The base 10 includes a frame 11, a bracket 12, a sleeve 13 and a hinged platform 14. The frame 11 stands on the ground. The bracket 12 extends upward from the four corner points of the frame 11 and folds inward to converge above the center of the frame 11. The bracket 12 has a sleeve 13 in the center, and a transmission part 30 is hinged in the sleeve 13. The front side of the frame 11 has a hinged platform 14, and a driving joint of the transmission part 30 is hinged on the hinged platform 14.

[0021] The working part 20 includes a turntable 21, a barrier 22, an axle seat 23 and a first hinge hole 24. The upper outer edge of the turntable 21 is provided with a barrier 22, which blocks the chip. The bottom of the turntable 21 is provided with an axle seat 23, which is docked with the transmission joint 31 of the transmission part 30 and is located on the sleeve 13. The axle seat 23 is provided with a first hinge hole 24, and a pin is installed in the first hinge hole 24 to connect the working part 20 with the transmission part 30.

[0022] The transmission part 30 includes a transmission joint 31, a transition joint 32, a shift fork 33, a compensation joint 34, a cross joint 35, a drive joint 36 and a drive rod 37. The transmission joint 31 includes a transmission shaft 311 and a rocker arm 312. The transmission shaft 311 is sleeved in the sleeve 13 and connected to the shaft seat 23 upward. The bottom of the transmission shaft 311 has a rocker arm 312, and the rocker arm 312 is hinged to the transition joint 32. The transition joint 32 is hinged to the shift fork 33. The rod end of the shift fork 33 has a pin hole 331, and the rod end of the shift fork 33 is sleeved in the docking hole 342 of the compensation joint 34. The front side of the compensation joint 34 also has a pair of limiting grooves 341. A pin is installed from the limiting groove 341 to the pin hole 331, so that the shift fork 33 is laterally limited in the compensation joint 34 and can be kept rotating around the rod end of the shift fork 33 to compensate for the lateral rotation of the rod system. Another fork 33 is installed at the other end of the joint 34 in the same way. The fork 33 is hinged to the cross joint 35, and the other direction of the cross joint 35 is hinged to the driving joint 36. The driving joint 36 includes a jaws 361 and an axle 362. The jaws 361 is connected to the cross joint 35. The bottom of the driving joint 36 has a transverse axle 362, and the axle 362 is hinged on the hinge platform 14 of the base 10. The end of the axle 362 of the driving joint 36 is connected to the driving rod 37. The front end of the driving rod 37 has a circular joint 371, and the circular joint 371 is sleeved on the axle 362 and fixedly connected. The rear end of the driving rod 37 has a pedal 372. Stepping on the pedal 372 can drive the working part 20 to rotate through the transmission part 30. As the turntable 21 rotates, the LED chips are gradually laid flat under the action of centrifugal force. Of course, there are two points that need to be supplemented here. First, the rotation speed of the turntable 21 needs to be reasonably controlled. If the rotation speed is too high, all the chips may be concentrated on the outer enclosure 22 of the turntable 21. If the rotation speed is too low, the chip flattening operation cannot be achieved. Second, for the convenience of description and illustration, the technical solution adopts manual pedaling as the driving source. Those skilled in the art can easily replace the driving rod 37 with other electrical or chemical energy driving methods.

[0023] The working principle of the present invention is: stepping on the driving rod 37 drives the driving joint 36 to swing back and forth on the hinged platform 14, and then, under the drive of each joint of the transmission part 30, the turntable 21 starts to rotate, and the rotating turntable 21 can keep the driving rod 37 swinging up and down under the drive of rotational inertia. As long as the driving rod 37 is properly stepped on continuously, the turntable 21 can be kept rotating. It should be supplemented that the compensation joint 34 can compensate for the slight twisting of the transmission part 30 when the transmission part 30 moves horizontally, and the cross joint 35 can compensate for the movement relationship between the driving joint 36 of the transmission part 30 and the fork 33.

[0024] The above embodiments mainly illustrate the LED chip tiling device of the present invention. Although only limited embodiments and technical features are described, those skilled in the art should understand that the present invention can be implemented in many other forms without departing from its spirit and scope. Therefore, the embodiments shown are regarded as illustrative rather than restrictive, and the present invention may cover various modifications and replacement schemes without departing from the spirit and scope of the present invention as defined in the appended claims.
