Description

Technical Field

[0001] The utility model relates to diode auxiliary processing equipment, in particular to an auxiliary feeding device for diode inspection. Background Art

[0002] A diode is an electronic device made of semiconductor material with two electrodes that allows current to flow in only one direction.

[0003] Basic Characteristics and Applications: Diodes have unidirectional conductivity, conducting when a forward voltage is applied and blocking when a reverse voltage is applied, acting as an electronic check valve. They are widely used in various electronic circuits to perform various functions, including rectification, detection, amplitude limiting, clamping, and voltage stabilization.

[0004] After production, the diodes are placed on a material board for transportation and then moved to the inspection area. The conveyor board needs to be raised during transportation, which is a manual operation during routine operation, resulting in inconvenience in loading and unloading operations and image inspection operations.

[0005] In view of the above-mentioned defects, the designers have actively carried out research and innovation in order to create an auxiliary loading device for diode inspection to make it more valuable for industrial use. Utility Model Content

[0006] In order to solve the above technical problems, the purpose of the utility model is to provide an auxiliary feeding device for diode inspection.

[0007] The utility model discloses an auxiliary loading device for diode inspection, comprising a frame, wherein the frame comprises two parallel conveying frames, and an upward movement mechanism for lifting a workpiece plate is provided at the rear end of the conveying frames.

[0008] The upward movement mechanism includes guide frames fixed upward on both sides of the conveyor frame, and a drive motor for transmission is installed on the guide frame. Sprocket mounting rollers are installed on the upper and lower sides of the guide frame, and a chain is installed between the sprocket mounting rollers. A plurality of card plates supporting the material plates are installed on the chain.

[0009] This auxiliary loading device for diode inspection can cyclically move the material plate upward through the upward movement mechanism, making it easier for the rear-end mechanism to take it, thereby completing the transfer of the workpiece plate and assisting in detection.

[0010] Furthermore, a horizontal plate is fixed below the right conveying frame, a lifting cylinder located inside the conveying frame is fixed to the horizontal plate, and a horizontal support plate is provided on the top of the lifting cylinder.

[0011] The lifting cylinder drives the cross support plate to move the workpiece plate up and away from the conveyor frame, making it easier for the upward movement mechanism to take the material plate.

[0012] Furthermore, a mounting rod is fixed between the conveying frames, and a limit plate for limiting movement is fixed on the mounting rod. The limit plate can be driven by a cylinder to perform a lifting operation.

[0013] After the limit plate moves upward, it can limit the movement of the workpiece plate to prevent the workpiece plate from leaving the conveyor frame.

[0014] Furthermore, the conveyor frame includes a conveyor motor fixed on its side wall, which drives the transfer shaft to rotate through a pulley and a belt. Multiple transmission wheels are installed on the inner side of the side wall of the conveyor frame, and the conveyor belt is installed around the transmission wheel.

[0015] The conveying motor drives the rotating shaft to rotate through the pulley and belt. A conveying belt is installed between the rotating shaft and the transmission wheel, so that the conveying motor drives the conveyor belt to run.

[0016] Furthermore, there is a support block on the inner side of the conveyor frame, and the support block is located between the conveyor belts.

[0017] The support block can support the conveyor belt to prevent the conveyor belt from being crushed by the material plate, causing the material plate to detach.

[0018] Through the above scheme, the present invention has at least the following advantages: this auxiliary loading device for diode inspection transfers the material plate at the front end through the conveyor frame and transports it to the loading mechanism position, can perform a lifting operation on the material plate and move it to the inspection equipment at the rear end for reset, and transfer the material plate to the inspection station through other transfer tools, thereby realizing the operation of raising the material plate and meeting the loading requirements.

DETAILED DESCRIPTION

[0026] The following embodiments are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0027] See Figure and Figure 2 The frame of this auxiliary feeding device for diode inspection consists of two parallel conveying frames 2. The conveying frames 2 can be spliced ​​to form a long strip feeding mechanism. One end of the conveying frame 2 is an upward movement mechanism 3, which can drive the material plate to perform upward feeding operations.

[0028] There is a chain 7 between the two parallel guide frames 4 of the upward movement mechanism 3 and the sprocket mounting rollers 6 installed on the guide frames 4. When the driving motor 5 drives one of the sprocket mounting rollers 6 to rotate, the chain 7 can be driven for transmission. At this time, the card plate 8 installed on the chain 7 can support the material plate, thereby completing the upward movement operation of the material plate.

[0029] See also Figure 2 The horizontal plate 9 is the mounting base, and the conveying frame 2 can be installed on the horizontal plate 9. The horizontal plate 9 is also equipped with a lifting cylinder 10 for lifting the cross support plate 11. The cross support plate 11 can contact the lower edge of the material plate. When the material plate is moved to the position of the upper movement mechanism 3, the material plate is driven to move up by the lifting cylinder 10. At this time, the material plate is separated from the conveying frame 2, and the card plate 8 on the upper movement mechanism 3 moves up from the bottom of the material plate along with the chain 7, and finally contacts the material plate, which can drive the material plate to move up and complete the loading operation.

[0030] See also Figure 3The mounting rod 12 is long and the cylinder for mounting the limit plate 13 can be fixed at any position of the mounting rod 12 to meet the limiting operation of material plates of different lengths. The initial position of the limit plate 13 is lower than the upper edge of the conveying rack 2. When the material plate needs to be limited, the limit plate 13 moves up to block the material plate from moving forward, and then cooperates with the lifting cylinder 10 to complete the lifting operation of the material plate, so that the relative position of each material plate is fixed during transfer, which is convenient for the later material taking operation.

[0031] See also Figure 4 The conveyor belt 17 of the conveyor frame 2 is driven by the conveyor motor 14. The conveyor motor 14 drives the adapter shaft 15 to rotate through a belt and a pulley. The two ends of the adapter shaft 15 are pulleys. A plurality of transmission wheels 16 are also installed on the inner side wall of the conveyor frame 2. The conveyor belt 17 is wound around the transmission wheel 16 and the pulley at one end of the transmission shaft 15 to complete the transmission connection. At this time, the conveyor motor 14 is working to complete the transmission of the conveyor belt 17, which is convenient for driving the material plate to move.

[0032] See also Figure 4 After the conveyor belt 17 is rotated and installed, a support block 18 is fixed between the gaps thereof. The support block 18 is installed on the inner side of the conveyor frame 2. After the conveyor belt 17 receives the material plate, it will be deformed under the gravity of the material plate. The support block 18 can provide support to prevent the material plate from detaching from the conveyor belt 17.

[0033] Finally, a few points should be explained: First, in the description of this application, it should be noted that, unless otherwise specified or limited, the terms "mounted," "connected," and "connected" should be understood in a broad sense, and may refer to mechanical or electrical connections, internal communication between two components, or direct connection. "Up," "down," "left," and "right" are only used to indicate relative positional relationships. When the absolute positions of the objects being described change, the relative positional relationships may also change.

[0034] Secondly: The drawings of the embodiments disclosed in this utility model only involve structures related to the embodiments disclosed in this utility model. Other structures can refer to common designs. In the absence of conflicts, the same embodiment and different embodiments of the utility model can be combined with each other.

[0035] Finally: The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. It should be pointed out that ordinary technicians in this technical field can make several improvements and modifications without departing from the technical principles of the present invention. These improvements and modifications should also be regarded as within the scope of protection of the present invention.
