Description

Technical Field

[0001] The invention relates to a sealing and testing device, and in particular to a feeding module of the sealing and testing device. Background Art

[0002] The turntable test printing and taping machine places bulk semiconductor transistors in a vibrating container and arranges them neatly into the machine track. It then uses numerous suction nozzles with air pressure suction on the high-speed rotating table to test the semiconductor transistors at different station processes. It goes through polarity testing, steering positioning, performance testing, visual inspection (2D, 3D, 5S), printing, and steering processes to classify unqualified products, and qualified products are finally taped and packaged.

[0003] refer to Figure 1 During packaging, the components in the linear track need to be sucked up by the vacuum nozzle of the picking mechanism. When the picking mechanism is close to the front end of the linear track, the small cam on the side of the picking mechanism lifts up the pressing mechanism on the side of the linear track so that the products in the linear track can reach the picking mechanism smoothly. The following abnormalities are prone to occur during the above process:

[0004] 1. When the small cam lifts the pressing mechanism, the material taking mechanism is usually not completely close to the linear track, and components are easy to fall off;

[0005] 2. Since the material of the pressing mechanism is alloy steel, it is easy to damage the product surface if it is not adjusted in place. Summary of the invention

[0006] In order to solve the above technical problems, the present invention provides a feeding module of a packaging and testing equipment, comprising a base, a servo motor and a sensor installed on the packaging and testing equipment, a mobile bracket installed on the base through a slider 1, a pickup head installed on the mobile bracket and a servo mechanism installed on the mobile bracket through a slider 2, the servo motor drives the mobile bracket to move horizontally on the base in cooperation with the slider 1 through a cam shaft, and a vacuum suction nozzle is arranged on the pickup head; it also includes a linear track, and a material pressing mechanism arranged corresponding to the linear track for positioning components on the linear track;

[0007] The servo mechanism includes a mounting block and a cylinder mounted on the movable bracket via a slider 2, the cylinder shaft of the cylinder is connected to the mounting block, a small cam is arranged on the mounting block, and the small cam corresponds to the pressing mechanism.

[0008] Wherein, the material of the pressing mechanism is antistatic material.

[0009] Wherein, the vacuum suction nozzle includes a mounting portion, a transition portion, a connecting portion and a suction head; the mounting portion is used for mounting and connecting with the mounting block; the transition portion is coaxially connected to the mounting portion; the suction head is coaxially connected to the transition portion through the connecting portion; the diameter of the connecting portion is smaller than the diameter of the suction head, the diameter of the suction head is smaller than the diameter of the transition portion, and the diameter of the transition portion is smaller than the diameter of the mounting portion.

[0010] Wherein, if the connection part is made of brittle material, when an adverse collision occurs, the connection part is disconnected to release the external force collision; or, if the connection part is made of flexible material, when an adverse collision occurs, the connection part is bent to buffer the external force collision.

[0011] Wherein, the two ends of the connecting portion are respectively detachably connected to the transition portion and the suction head, such as threaded connection, so that when an undesirable condition occurs, the connecting portion and the suction head can be directly replaced by disassembly; or, the two ends of the connecting portion are respectively non-detachably connected to the transition portion and the suction head, such as welding, so that when an undesirable condition occurs, the entire vacuum nozzle can be directly replaced by disassembly.

[0012] Through the above technical solution, the present invention has the following beneficial effects:

[0013] 1. When the servo motor cooperates with the camshaft and the slider 1 to drive the mobile bracket to move to the linear track, the small cam has not yet lifted the pressing mechanism. At this time, the vacuum nozzle of the pickup head corresponds to the top of the components on the linear track; then the cylinder cooperates with the slider 2 to drive the mounting block on the mobile bracket to move to a certain position on the linear track again, and the small cam lifts the pressing mechanism and releases the components. At this time, the components can be adsorbed by the vacuum nozzle and moved to the position of the tape track to release the components. This two-step separate movement design can ensure that the components are released by the pressing mechanism only after the mobile bracket is fully in contact with the linear track, thereby effectively solving the problem of material drop;

[0014] 2. The pressure mechanism designed with anti-static materials can effectively prevent IC components from being crushed;

[0015] 3. By setting the original integrated suction nozzle to a segmented type, and connecting it with a small-diameter brittle or flexible connection in the middle, when impacted by external force, the brittle breakage or flexible bending of the connection part can eliminate the damage of the external force to other parts, thereby effectively protecting other parts connected to the vacuum suction nozzle. Subsequently, only partial replacement of the suction head or replacement of the vacuum suction nozzle as a whole is required. BRIEF DESCRIPTION OF THE DRAWINGS

[0024] When working based on Example 1, the servo motor 10 cooperates with the camshaft and the slider 1 20 to drive the mobile bracket 12 to move to the linear track 16 when the small cam 14 has not yet lifted the pressing mechanism 17. At this time, the vacuum suction nozzle 30 of the picking head 13 corresponds to the top of the component 18 on the linear track 16; then the cylinder 22 cooperates with the slider 21 to drive the mounting block 23 on the mobile bracket 12 to move to a certain position toward the linear track 16 again, and the small cam 14 lifts the pressing mechanism 17 and releases the component 18. At this time, the component 18 can be adsorbed by the vacuum suction nozzle 30 and moved to the position of the braiding track to release the component 18. This two-step separate movement design can ensure that the component 18 is released by the pressing mechanism 17 only after the mobile bracket 12 is fully and completely in contact with the linear track 16, thereby effectively solving the problem of material falling; the pressure mechanism designed with anti-static materials can effectively prevent the IC component 18 from being crushed.

[0025] Embodiment 2:

[0026] refer to Figure 3 The vacuum nozzle 30 includes a mounting portion 31, a transition portion 32, a connecting portion 33 and a suction head 34; the mounting portion 31 is used for mounting and connecting with the mounting block 23; the transition portion 32 is coaxially connected with the mounting portion 31; the suction head 34 is coaxially connected with the transition portion 32 through the connecting portion 33; the diameter of the connecting portion 33 is smaller than the diameter of the suction head 34, the diameter of the suction head 34 is smaller than the diameter of the transition portion 32, and the diameter of the transition portion 32 is smaller than the diameter of the mounting portion 31.

[0027] Among them, the connection part 33 is made of brittle material, and when an adverse collision occurs, the connection part 33 is disconnected to release the external force collision; or, the connection part 33 is made of flexible material, and when an adverse collision occurs, the connection part 33 bends to buffer the external force collision; the two ends of the connection part 33 are detachably connected to the transition part 32 and the suction head 34 respectively, such as threaded connection, and when an adverse condition occurs, the connection part 33 and the suction head 34 can be directly replaced by disassembly; or, the two ends of the connection part 33 are non-detachably connected to the transition part 32 and the suction head 34 respectively, such as welding, and when an adverse condition occurs, the entire vacuum suction nozzle 30 can be directly replaced by disassembly.

[0028] In this embodiment 2, the original integrated suction nozzle is configured as a segmented type, and the middle is connected by a small-diameter brittle or flexible connection part 33. When impacted by external force, the brittle fracture or flexible bending of the connection part 33 can eliminate the damage of the external force to other parts, thereby effectively protecting other parts connected to the vacuum suction nozzle 30. Subsequently, only partial replacement of the suction head 34 or replacement of the vacuum suction nozzle 30 as a whole is required.
