Description

Technical Field

[0001] The utility model relates to the technical field of a feeding device for a full inspection machine, in particular to a feeding device for an electronic chip CCD full inspection machine. Background Art

[0002] CCD full inspection machine is a device used for electronic chip inspection. It uses CCD as an image sensor to obtain images of the chip, and performs comprehensive chip inspection and quality control by analyzing and processing these images. Generally, CCD full inspection machines are equipped with a feeding device to feed and load the objects to be inspected.

[0003] The patent specification with announcement number CN215430324U discloses an automatic feeding device for a CCD full inspection machine for injector terminal blocks. At the same time, the operation of a robotic arm is controlled by a PLC controller. The robotic arm picks up the product and moves it to the moving track on the CCD full inspection machine. The product is placed on the inspection device for inspection by the robotic arm on the CCD full inspection machine. After the robotic arm has taken the product for a period of time, the conveyor belt is controlled to move by the PLC controller, and other rectangular plates can be moved to the position of the fixed plate to continue to pick up materials. At the same time, the staff places the product inside the rectangular block at one end of the rectangular frame to continuously feed the product. The device can facilitate automatic loading of products and position the products during loading, saving time and improving work efficiency. It also reduces the labor intensity of staff and is easy and simple to operate.

[0004] However, in the implementation of relevant technologies, it was found that the automatic feeding device of the injector terminal CCD full inspection machine designed above has the following problems: in the prior art, electronic chips are picked up and loaded through components such as PLC controllers and robotic arms, but during use, workers are required to place a single product inside the corresponding rectangular block at one end of the rectangular frame, which wastes manpower and has high labor intensity. In view of this, a feeding device of an electronic chip CCD full inspection machine is provided to overcome the above-mentioned defects. Utility Model Content

[0005] The utility model aims to solve the shortcomings in the prior art and proposes a feeding device for an electronic chip CCD full inspection machine.

[0006] In order to achieve the above-mentioned purpose, the utility model adopts the following technical scheme: a feeding device of an electronic chip CCD full inspection machine, comprising an upper hopper, a first conveying device is arranged at the bottom of the upper hopper, and a separation barrel is arranged at one end of the first conveying device, and a separation mechanism is arranged inside the separation barrel;

[0007] The separation mechanism includes a motor, which is embedded in the top center position of the separation barrel, and a driving rod is connected to the power output end of the motor, and a pushing block is fixed to one end of the driving rod that penetrates into the separation barrel, and the outer wall of the pushing block is connected to a limiting plate, and a mounting frame is fixed to the outer wall of the separation barrel, and a second conveying device is embedded inside the mounting frame. When the electronic chip is transported from the upper hopper to the inside of the separation barrel through the first conveying device, the motor drives the driving rod at the same time, so that the pushing block drives the electronic chip to move outward by centrifugal motion, and pass through the separation barrel for individual separation, thereby avoiding manual picking, reducing labor intensity and improving processing efficiency.

[0008] As a further description of the above technical solution: the pushing block fits tightly with the separation barrel, and the pushing block is detachably connected to the limiting plate by bolts, and the limiting plate is used to avoid the stacking of electronic chips during the pushing process.

[0009] As a further description of the above technical solution: a feed port is provided at the top of the upper hopper, and a guide block is fixed inside the upper hopper. The guide block is inclined to facilitate guiding the electronic chips to move to the outlet of the upper hopper, and at the same time, directly introduce a number of electronic chips into the upper hopper, avoiding the need for staff to pick up and transfer them, thereby reducing human resources.

[0010] As a further description of the above technical solution: a mounting plate is fixed to the outer wall of the upper hopper, and a rotating rod is inserted into the top of the mounting plate, and one end of the rotating rod passing through the mounting plate is rotatably connected to the lower pressure plate, the rotating rod is threadedly connected to the mounting plate, and the bottom end is rotatably connected to the lower pressure plate via a bearing, and the distance between the lower pressure plate and the first conveying device is adjusted by twisting the rotating rod, and it is adjusted according to the thickness of different electronic chips, thereby avoiding the penetration of stacked electronic chips and improving applicability.

[0011] As a further description of the above technical solution: a limiting mechanism is arranged on one side of the second conveying device, and the limiting mechanism includes a micro push rod, and the micro push rod is embedded in both sides of the inside of the mounting frame, and the power output end of the micro push rod is connected to a clamping plate, and a pressure sensor is embedded on one side of the second conveying device inside the mounting frame. When the electronic chip enters the second conveying device, the clamping plate is pushed by the micro push rod to limit the size of the current corresponding electronic chip, thereby keeping the electronic chip able to be conveyed to the position of the pressure sensor, and electronic chips of different sizes can be adapted by adjusting the micro push rod.

[0012] As a further description of the above technical solution: the limiting mechanism also includes a roller, which is rotatably connected to the outer wall of the clamping plate, and a telescopic block is fixed to one end of the clamping plate close to the separation barrel, one end of the telescopic block is fixed to the mounting frame, and the other end is fixed to the clamping plate, so that when the clamping plate slides, the telescopic block follows and extends, avoiding reserving space for the electronic chip to slip out of the separation barrel due to the position offset between the two sets of clamping plates.

[0013] As a further description of the above technical solution: the rollers are evenly distributed about the outer wall of the clamping plate, and the clamping plate forms a sliding structure with the mounting frame through a micro push rod. The rollers improve the smoothness of sliding of the electronic chip and avoid excessive friction between the clamping plate and the electronic chip that affects sliding and even causes damage.

[0014] The utility model has the following beneficial effects:

[0015] The utility model designs a feeding device for an electronic chip CCD full inspection machine, which introduces the electronic chip into an upper hopper, and is guided by a material guide block and cooperates with a first conveying device to convey the electronic chip into a separation barrel, and a motor drives a driving rod to allow a pushing block to push the electronic chip for centrifugal motion, thereby sliding outward and sliding out through an outlet of the separation barrel for single separation, thereby avoiding manual single picking and placement, reducing labor intensity and waste of human resources, and providing three sets of mounting frames and a second conveying device, so as to facilitate the simultaneous conveying of three single separated electronic chips to the corresponding full inspection machine, thereby improving the efficiency of detection.

[0016] The utility model designs a feeding device for an electronic chip CCD full inspection machine. Under the support of a mounting plate, a rotating rod is twisted to adjust the distance between a lower pressure plate and a first conveying device, so that it is convenient to adjust according to the thickness of the electronic chip to avoid stacking during the conveying process. Subsequently, when the electronic chip passes through a separation barrel, a micro push rod pushes a clamping plate to limit the electronic chip from both sides, so that the electronic chip reaches a pressure sensor and triggers control through a general control end of the feeding device to allow the corresponding full inspection machine to perform inspection and the corresponding second conveying device to stop, so as to avoid stacking. The roller improves the smoothness of the electronic chip conveying process and avoids external damage caused by excessive friction. BRIEF DESCRIPTION OF THE DRAWINGS

[0025] Reference Figure 1-6 The utility model provides a feeding device for an electronic chip CCD full inspection machine: it includes an upper hopper 1, a first conveying device 2 is arranged at the bottom of the upper hopper 1, a separation barrel 3 is arranged at one end of the first conveying device 2, and a separation mechanism 4 is arranged inside the separation barrel 3; the separation mechanism 4 includes a motor 401, the motor 401 is embedded in the top center position of the separation barrel 3, the power output end of the motor 401 is connected with a driving rod 402, and a pushing block 403 is fixed at one end of the driving rod 402 that penetrates into the separation barrel 3, the outer wall of the pushing block 403 is connected to a limiting plate 404, and a mounting frame 405 is fixed on the outer wall of the separation barrel 3, and a second conveying device 406 is embedded inside the mounting frame 405. When the electronic chip is transported from the upper hopper 1 to the inside of the separation barrel 3 through the first conveying device 2, the motor 401 drives the driving rod 402 at the same time, so that the pushing block 403 drives the electronic chip to move outward by centrifugal motion, and passes through the separation barrel 3 for single separation, avoiding manual picking, reducing labor intensity and improving processing efficiency.

[0026] As a further implementation scheme of the above technical scheme: the pushing block 403 fits tightly with the separation barrel 3, and the pushing block 403 is detachably connected to the limiting plate 404 by bolts. The limiting of the limiting plate 404 can avoid the stacking of electronic chips during the pushing process.

[0027] As a further implementation scheme of the above technical scheme: a feeding port 5 is opened at the top of the upper hopper 1, and a guide block 6 is fixed inside the upper hopper 1. The guide block 6 is inclined to facilitate guiding the electronic chips to move to the outlet of the upper hopper 1. At the same time, a number of electronic chips are directly introduced into the upper hopper 1, avoiding the need for staff to take and pass them, thereby reducing human resources.

[0028] During specific implementation, the electronic chip is introduced into the upper hopper 1, and under the guidance of the guide block 6, it is transmitted to the separation barrel 3 through the first conveying device 2, and then the motor 401 drives the driving rod 402 so that the pushing block 403 moves the electronic chip to perform centrifugal motion, diffuse and slide outward and slide out through the outlet of the separation barrel 3 for individual separation. The limiting plate 404 is used to prevent the electronic chips from stacking up. At the same time, the mounting frame 405 and the second conveying device 406 cooperate to convey the electronic chips to the full inspection machine position.

The power output end of the micro push rod 1001 is connected to the clamping plate 1002, and a pressure sensor 1003 is embedded on one side of the second conveying device 406 inside the mounting frame 405. When the electronic chip enters the second conveying device 406, the clamping plate 1002 is pushed by the micro push rod 1001 to limit the size of the current corresponding electronic chip, thereby keeping the electronic chip able to be transported to the position of the pressure sensor 1003. By adjusting the micro push rod 1001, electronic chips of different sizes can be used.

[0032] As a further implementation scheme of the above technical scheme: the rollers 1004 are evenly distributed on the outer wall of the clamping plate 1002, and the clamping plate 1002 forms a sliding structure with the mounting frame 405 through the micro push rod 1001. The rollers 1004 improve the smoothness of sliding of the electronic chip and avoid excessive friction between the clamping plate 1002 and the electronic chip that affects sliding and even causes damage.

[0033] During the specific implementation, the rotating rod 8 is turned to adjust the position of the lower pressure plate 9 according to the thickness of the electronic chip. The clamping plate 1002 is driven by the micro push rod 1001 to adjust according to the size of the electronic chip. The electronic chip is allowed to slide along the center line of the second conveying device 406 until it reaches the pressure sensor 1003. After sensing, the whole inspection machine is controlled to perform inspection through the main control end of the feeding device. The inspection point of the full inspection machine is above the pressure sensor 1003. After the inspection is completed, it can be taken by the staff.
