[0002] LED patch bracket detection is an important link in the LED production process, which is used to detect the quality and stability of the bracket in the LED lamp. LED patch bracket usually refers to the bracket where the LED chip is soldered on the PCB (printed circuit board). Its quality directly affects the stability, heat dissipation and life of the LED lamp. Therefore, it is of great significance to detect the LED patch bracket. With the widespread application of LED lighting products in the market, LED patch bracket detection has become an indispensable part of the LED production process. Through comprehensive testing of the appearance, structure, material, durability and safety of the LED patch bracket, the quality and stability of the LED lamp can be ensured, and the reliability and safety of the product can be improved. Therefore, the background of LED patch bracket detection is the rapid development of the LED lighting industry and the improvement of product quality requirements, as well as the need for quality control of key components in the LED production process. Through LED patch bracket detection, the performance of LED lamps can be ensured to be stable and safe and reliable during use.

[0003] The LED patch bracket is based on the bracket, the chip is fixed into the bracket, and then the positive and negative electrodes are welded, and the packaging glue is used to encapsulate it in one step. The LED patch bracket cannot have cracks when in use, so the LED patch bracket needs to be cracked after production is completed. By placing the LED patch bracket into the detection machine and scanning it with the instrument, the display screen of the detection machine will show whether there are cracks.

[0004] After searching, the Chinese patent application number CN2021106933214 discloses an automatic detection device and method for the appearance defects of an LED patch bracket, including a frame, a group of conveying rollers are provided in the frame to rotate along its length direction, and the conveying rollers are externally connected to a conveyor belt, the four corners of the lower end face of the frame are connected to support columns, and a load-bearing plate is connected between the support columns, the upper end face of the frame is symmetrically provided with two groups of columns, and the tops of the columns are commonly connected to a top plate, and a slide is provided on the columns, and a roller that fits the columns is provided in the slide. The present invention fixes the LED patch bracket by a splint, and the LED patch bracket can be flipped by a flipping structure, so that the detection head can perform appearance inspection on each side of the LED patch bracket, significantly improving the accuracy of the appearance inspection, and at the same time, the degree of automation is better, thereby improving the efficiency of the appearance inspection of the LED patch bracket. An automatic detection device and method for the appearance defects of an LED patch bracket in the above patent has the following shortcomings:

[0005] Although the overall device uses a buzzer alarm to remind the operator to transfer the unqualified LED patch bracket, there is no need for the operator to check regularly, thus reducing the operator's workload. However, when the detection machine is testing the LED patch bracket, only one LED patch bracket can be placed in the detection machine at a time, and it cannot be turned over. Summary of the invention

[0006] The purpose of the present invention is to solve the shortcomings of the prior art and to propose an LED bracket detection device.

[0007] In order to achieve the above object, the present invention adopts the following technical solutions:

[0008] LED bracket detection equipment includes a detection box, wherein the outer wall of one side of the front side of the detection box is connected to a box door through a hinge, and the outer wall of the back side of the detection box is fixed with a mounting plate through bolts, a moving mechanism is arranged on the top of the mounting plate, the moving end of the moving mechanism is fixedly connected with the chassis, the front outer wall of the chassis is fixedly connected with a fixing plate, the bottom outer wall of the fixing plate is fixedly connected with a scanner, and a flipping mechanism is arranged on the front outer wall of the mounting plate, the output end of the flipping mechanism is fixedly connected with a connecting plate, LED patch brackets are respectively arranged on both sides of the connecting plate through a receiving mechanism, a baffle is fixedly connected to the top outer wall of the connecting plate, and scale lines are arranged on the top front side of the mounting plate.

[0009] Preferably: the moving mechanism includes a fixed rack plate, a motor, a sliding plate and a moving gear, and the fixed rack plate is fixed to both sides of the top of the mounting plate by bolts, the sliding plate is slidably connected to both sides of the fixed rack plate, and the motor is fixed to the outer wall of the back side of the sliding plate by a support plate.

[0010] On the basis of the above scheme: the movable gear is connected to the output shaft end of the motor through a coupling, the movable gear and the fixed rack plate are meshed with each other, and the back outer wall of the chassis is connected and fixed to the front of the sliding plate through bolts.

[0011] By starting the motor to drive the moving gear to rotate, the rotating moving gear moves horizontally on the fixed rack plate. At the same time, the sliding plate slides horizontally on the fixed rack plate, and then the moving sliding plate drives the chassis on one side to move, and the scanner on one side of the chassis realizes linear motion synchronously, ensuring all-round scanning of the LED patch brackets on both sides of the connecting plate, meeting the requirements of comprehensive detection of the LED patch brackets, and improving the efficiency of LED patch bracket detection.

[0012] A better solution among the above solutions is: the flipping mechanism includes a guide rail, a slider, a mounting block, a hydraulic rod, a guide plate, a sliding hole, a swing plate, a mounting shaft, a limit column and an arc groove, and the hydraulic rod is fixed to the outer wall on one side of the bottom of the mounting plate by bolts, the mounting block is connected to the piston rod end of the hydraulic rod by threads, the guide rail is fixed to the front side of the mounting plate by bolts, and the sliding hole is opened on the outer wall of the mounting plate on one side close to the guide rail.

[0013] As a further solution of the present invention: the slider is slidably connected to the front side of the guide rail, the guide plate is connected to one side of the mounting block by bolts, and the front side of the slider is connected to the back side of the guide plate by bolts, the mounting shaft is rotatably connected to the end of the guide plate away from the guide rail, and the swing plate is threadedly connected to the circumference of the mounting shaft.

[0014] At the same time, a sliding fit is formed between the tail end of the mounting shaft and the sliding hole, and the limiting column is fixed to the outer wall of the mounting plate close to the sliding hole at equal distances through threads, and one side of the swing plate is provided with grooves distributed at equal distances, which are adapted to the limiting column, and the other side of the swing plate is an arc structure.

[0015] As a preferred embodiment of the present invention: an arc groove is opened on one side of the mounting plate close to the sliding hole, and the arc structure forms a sliding fit with the arc groove, and one end of the connecting plate is connected to the end of the mounting shaft through a thread.

[0016] By starting the hydraulic rod, the hydraulic rod drives the guide plate on one side of the mounting block vertically upward, and synchronously drives the slider on the back thereof to move vertically on the guide rail. At the same time, the guide plate drives the swing plate upward, and one side of the arc-shaped structure of the swing plate fits with the arc-shaped groove, so that the swing plate can be flipped. During the flipping of the swing plate, the groove of the swing plate away from its arc structure fits and engages with the limit column, and the tail end of the mounting shaft at the center of the swing plate moves vertically in the sliding hole. During the flipping of the swing plate, the connecting plate at the end of the mounting shaft also flips accordingly, and the flipping angle is one hundred and eighty degrees, and the LED patch brackets located on both sides of the connecting plate realize the flipping function. Therefore, the multiple LED patch brackets located on both sides of the connecting plate can complete the detection work synchronously, which solves the problem that when the traditional detection machine detects the LED patch bracket, only one LED patch bracket can be placed in the detection machine for detection at a time, thereby improving the efficiency of the LED patch bracket detection.

[0017] At the same time, the supporting mechanism includes a magnetic gasket, a support plate and a limiting side plate. The support plate is respectively bonded to the outer walls on both sides of the connecting plate, and the magnetic gasket is bonded to the joint between the support plate and the LED patch bracket. The support plate is fixedly connected to the limiting side plates on both sides close to the magnetic gasket.

[0018] As a more preferred solution of the present invention: a mounting port is snap-connected to an outer wall of one side of the chassis close to the scanner, and a guide interface is threadedly connected to a rear end side of the scanner.

[0019] Furthermore: a fill light ring is connected to the top outer wall of the scanner via threads.

[0020] The beneficial effects of the present invention are:

[0021] 1. The LED bracket detection equipment starts the hydraulic rod, which drives the guide plate on one side of the mounting block vertically upward, and synchronously drives the slider on the back thereof to move in the vertical direction on the guide rail, and at the same time the guide plate drives the swing plate upward, and one side of the arc structure of the swing plate fits with the arc groove, so that the swing plate can be flipped. During the flipping of the swing plate, the groove of the swing plate away from its arc structure fits with the limit column, and the tail end of the mounting shaft at the center of the swing plate moves vertically in the sliding hole. During the flipping of the swing plate, the connecting plate at the end of the mounting shaft also flips accordingly, and the flipping angle is 180 degrees, and the LED patch brackets located on both sides of the connecting plate realize the flipping function. Therefore, the multiple LED patch brackets located on both sides of the connecting plate can synchronously complete the detection work, which solves the problem that when the traditional detection machine detects the LED patch bracket, only one LED patch bracket can be put into the detection machine for detection at a time, thereby improving the efficiency of the LED patch bracket detection.

[0022] 2. The LED bracket detection equipment drives the moving gear to rotate by starting the motor. The rotating moving gear moves horizontally on the fixed rack plate. At the same time, the sliding plate slides horizontally on the fixed rack plate. Then the moving sliding plate drives the chassis on one side to move, and the scanner on one side of the chassis realizes linear motion synchronously, ensuring the all-round scanning of the LED patch brackets on both sides of the connecting plate, meeting the requirements of comprehensive detection of LED patch brackets, and improving the efficiency of LED patch bracket detection.

[0023] 3. When installing the LED patch bracket, the LED bracket detection equipment only needs to fit the bottom of the LED patch bracket to the front and back sides of the support plate through the magnetic gasket, and make the LED patch bracket as a whole clamped between the two limit side plates to complete the fixation of the LED patch bracket. At the same time, open the installation port at the bottom of the chassis, connect the installation port and the guide interface of the scanner through the connecting wire, and turn on the fill light to avoid the weak ambient light affecting the image quality taken by the scanner. In this way, not only the electrical connection between the scanner and the chassis is realized, but also the loading and unloading of the LED patch bracket is convenient, thereby improving practicality.
