Description

Technical Field

[0001] This invention relates to the field of die bonder technology, and more specifically to a die bonder feeding mechanism. Background Technology

[0002] The die bonder mainly consists of a feeding mechanism, a worktable track, a dispensing mechanism, a pick-up mechanism, a wafer platform, a wafer changing mechanism, a pin mechanism, and an unloading mechanism. After the product is transferred from the feeding mechanism to the dispensing mechanism, the vision system on the dispensing mechanism positions it and dispenses the adhesive. After the product is transferred to the pick-up mechanism, the pin mechanism detaches the chip from the wafer platform, and the pick-up mechanism removes the detached chip and solders it onto the product. After the chip is attached to the product, it is transferred to the unloading mechanism.

[0003] However, in the prior art, when feeding the material, the material is placed in multiple layers inside the material box. The material box is placed on one side of a conveyor belt mechanism that can move and rotate horizontally. The conveyor belt mechanism first moves the material under the material inserted into the material box. Then, as the conveyor belt rotates, it transports the material contacted on the upper side to the lower side of the dispensing component. After dispensing is completed, the conveyor belt reverses to push the dispensed material back into the material box. After the conveyor belt moves out of the material box, it controls the material box to move up one layer, so that the conveyor belt moves to the lower side of the next material, and then moves the next material out.

[0004] However, after the conveyor belt is inserted into the lower side of the material plate in the material box, in order to ensure that the conveyor mechanism does not collide with the material plate, the upper side of the conveyor belt is inserted into the lower side of the material plate at a certain distance from the bottom surface of the material plate. The conveyor belt and the material plate will move vertically again to ensure that the conveyor belt can contact and convey the material plate. However, the material plate is stuck in the horizontal groove of the material box. When the conveyor belt pushes the material plate upward, the material plate is pushed and collides with the groove in the material box. The material plate is prone to bending and deformation, which affects the quality of the material plate. Summary of the Invention

[0005] To address the problems mentioned in the background section, the present invention provides the following technical solution:

[0006] A die bonder feeding mechanism includes a support frame, a conveyor belt mechanism installed on the upper end of the support frame for linearly conveying a material plate, a material control mechanism located on the upper side of the support frame next to the conveyor belt mechanism for fixing a material box, and an auxiliary pusher located on the side of the material control mechanism away from the conveyor belt mechanism. The auxiliary pusher is driven to move horizontally by the conveyor belt mechanism during rotation.

[0007] It also includes: two limiting side plates, the material control mechanism is slidably inserted between the two limiting side plates, and one of the limiting side plates is equipped with a power telescopic rod for controlling the up and down movement of the material control mechanism.

[0008] Furthermore, the conveyor belt mechanism includes two side frames and two conveyor belts. The two conveyor belts are located between the two side frames and are driven by two conveyor rollers. Each conveyor roller is rotatably connected to the two side frames at both ends. One of the two conveyor rollers, which is closer to the material control mechanism, outputs power to the transmission mechanism. The lower end of the side frame is fixed to the support frame.

[0009] Furthermore, the material control mechanism includes a bottom support plate and two clamping frames. The bottom support plate is slidably sleeved on the lower ends of the two clamping frames. A power bidirectional threaded shaft is rotatably installed on the bottom surface of the bottom support plate. The power bidirectional threaded shaft rotates relative to the bottom support plate. The lower ends of the two clamping frames are respectively threaded onto the two ends of the power bidirectional threaded shaft. The power telescopic rod is fixed to the bottom support plate. The bottom support plate is slidably inserted between two limiting side plates.

[0010] Furthermore, the transmission mechanism includes two magnetically shielded gears and two transmission gear plates. The two magnetically shielded gears are coaxially mounted with both ends of the conveyor roller near the material control mechanism. The magnetically shielded gears rotate relative to the conveyor roller. Multiple magnetically attracting rods are fixedly mounted on the inner ring surface of the magnetically shielded gears and are evenly distributed around the circumference. Magnetic attracting rods are provided on the inner side of the magnetically shielded gears and are mounted on the surface of the corresponding conveyor rollers. The two transmission gear plates mesh with the upper side of the two magnetically shielded gears respectively. The two side frames are laterally slidably connected to movable frames on opposite sides. The two transmission gear plates are fixed to the two movable frames respectively.

[0011] The other ends of the two movable frames are fixed by a connecting plate, and the middle part of the connecting plate near the side frame is fixed to the auxiliary push frame.

[0012] Furthermore, each of the two side frames is fixed with a horizontal telescopic rod on a side away from each other, and the telescopic ends of the two horizontal telescopic rods are respectively fixed to the two movable frames.

[0013] Furthermore, an extended sliding plate is fixed to one end of each of the two side frames near the bottom support plate. The upper surface of the extended sliding plate is flush with the upper surface of the conveyor belt, and the end of the extended sliding plate away from the conveyor belt is an inclined surface that slopes downward.

[0014] Furthermore, a vertical plate is fixed to the bottom surface of the extended sliding plate, and the lower end of the vertical plate slides through the upper surface of the bottom support plate. The lower end of the vertical plate is fixed to the upper surface of the support frame.

[0015] Furthermore, each of the two clamping frames is provided with a side positioning plate on the side away from each other at the upper end, and the other ends of the two side positioning plates are bent close to each other. A long groove is opened on the side positioning plate near the corresponding clamping frame, and a bolt rod is provided in the long groove. The bolt rod is threaded to the adjacent clamping frame.

[0016] The mobile frame consists of two telescopic sections, which are fixed together by bolts.

[0017] Furthermore, a movable block is slidably inserted into one end of the auxiliary pusher away from the connecting plate. A sleeve rod connected to the movable block is provided inside the auxiliary pusher. A push gear is rotatably installed inside the connecting plate. An elastic element is connected to one side of the sleeve rod near the movable block. A positioning block that slides inside the sleeve rod is fixed at the other end of the elastic element. A push tooth plate that penetrates the sleeve rod is fixed at the other side of the positioning block. The other end of the push tooth plate slides through the outside of the connecting plate and meshes with the push gear. Trigger elements are provided at both ends of the push gear.

[0018] Furthermore, the trigger includes an extension gear, and both ends of the push gear are coaxially fixed with extension gears. Both extension gears have extension tooth plates meshing on their upper sides. The connecting plate is slidably sleeved on the outer surface of the two extension tooth plates. The two extension tooth plates are elastically connected to the connecting plate at one end outside the connecting plate. The two extension tooth plates correspond to the front and rear sides of the material box, respectively.

[0019] In summary, the present invention has the following beneficial effects:

[0020] 1. This invention utilizes the power of the conveyor belt mechanism to convert into the horizontal movement of the auxiliary pusher. With the use of the extended sliding plate, the material plate of the corresponding height is pushed to the upper side of the conveyor belt mechanism for discharge through the extended sliding plate. There is no lateral compression throughout the process, and the feeding operation is completed without damaging the material plate. This avoids the bending and deformation that can easily occur when the material plate is lifted vertically in the traditional way. Moreover, the pushing and resetting operations of this design are driven by the conveyor belt mechanism, without the need for an additional driving source.

[0021] 2. This invention utilizes the meshing of a magnetically shielded gear and a transmission gear plate to drive the moving frame and auxiliary pusher to move synchronously and achieve automatic pushing. When the conveyor roller rotates, it can apply a magnetic attraction force to the magnetic attracting rod through the magnetic attracting rod to drive the magnetically shielded gear to rotate. With the use of the horizontal telescopic rod, when the material plate encounters a sudden increase in pushing resistance due to foreign objects or other reasons, and the pushing resistance exceeds the threshold, the magnetically shielded gear will slip relative to the conveyor roller and spin freely, cutting off the power transmission to the auxiliary pusher and eliminating the risk of the material plate being squeezed and deformed due to forced pushing.

[0022] 3. In conjunction with the movable block propulsion structure at the end of the auxiliary pusher, when the auxiliary pusher pushes the material plate to move towards the conveyor belt mechanism, it triggers the extension tooth plate drive adjustment to move the tooth plate synchronously. Under the elastic action of the elastic element, the movable block is controlled to extend simultaneously during horizontal movement, forming a continuous action of "nested extension during propulsion". This can compensate for the gap error between the material box and the conveyor belt, ensuring that the material plate falls stably into the effective area of ​​the conveyor belt, avoiding the deviation caused by inertia in traditional single-stage propulsion. Moreover, this extension process is a flexible thrust, which can reduce impact damage to the material plate. Attached Figure Description

[0037] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention. Example

[0038] Please see Figure 1-11 The present invention provides a technical solution: a die bonder feeding mechanism, including a support frame 1, which is installed at the bottom of the die bonder. A conveyor belt mechanism 2 is installed on the upper end of the support frame 1. The conveyor belt mechanism 2 linearly conveys the upper material plate. A material control mechanism 3 is provided on the upper side of the support frame 1, located on one side of the conveyor belt mechanism 2. The material plate is inserted in multiple layers into the sliding grooves inside the material box. Corresponding material grooves are opened on the inner walls of both sides of the material box. The material control mechanism 3 fixes the material box. An auxiliary pusher 4 is provided on the side of the material control mechanism 3 away from the conveyor belt mechanism 2.

[0039] As the conveyor belt mechanism 2 rotates, it drives the auxiliary pusher 4 to move horizontally through the transmission mechanism 7. When the conveyor belt mechanism 2 delivers the material belt to the lower side of the dispensing mechanism, it drives the auxiliary pusher 4 to move towards the inside of the material box through the transmission mechanism 7, pushing the material plate corresponding to the upper side of the conveyor belt mechanism 2 to the upper side of the conveyor belt mechanism 2. When the conveyor belt mechanism 2 reverses and pushes the dispensed material plate back into the material box, the auxiliary pusher 4 resets during the transmission of the transmission mechanism 7.

[0040] The conveyor belt mechanism 2 includes two side frames 21 and two conveyor belts 22. The two conveyor belts 22 are located between the two side frames 21. The two conveyor belts 22 are driven by two conveyor rollers 23. The two ends of each conveyor roller 23 are rotatably connected to the two side frames 21 respectively. The conveyor roller 23 closer to the material control mechanism 3 outputs power to the transmission mechanism 7. The lower end of the side frame 21 is fixed to the support frame 1. A first motor is installed on one side of the side frame 21. The conveyor roller 23 away from the material control mechanism 3 is connected to the output end of the first motor. The forward and reverse rotation of the first motor controls the forward and reverse rotation of the conveyor belt 22 respectively.

[0041] In this embodiment, the die bonder feeding mechanism further includes two limiting side plates 5, and the material control mechanism 3 is slidably inserted between the two limiting side plates 5.

[0042] The material control mechanism 3 includes a base plate 31 and two clamping frames 32. The base plate 31 is slidably sleeved on the lower end of the two clamping frames 32. A power bidirectional threaded shaft 33 is rotatably mounted on the bottom surface of the base plate 31. The power bidirectional threaded shaft 33 rotates relative to the base plate 31. A second motor is mounted on the bottom surface of the base plate 31. The power bidirectional threaded shaft 33 is connected to the output end of the second motor. The lower ends of the two clamping frames 32 are respectively threaded onto the two ends of the power bidirectional threaded shaft 33. In order to fix the material box, during use, the forward and reverse rotation of the power bidirectional threaded shaft 33 drives the two clamping frames 32 to move closer and further away from each other, respectively. The material box is placed between the two clamping frames 32. When the two clamping frames 32 are close together, the material box can be fixed. It should be noted that when the two clamping frames 32 fix the material box, the strength of the material used for the clamping frames 32 is less than the strength of the material box, so as to avoid damage caused by clamping the material box.

[0043] The bottom support plate 31 moves vertically between the two limiting side plates 5 when it moves up and down.

[0044] One of the limiting side plates 5 is equipped with a power telescopic rod 6 that controls the material control mechanism 3 to move up and down. The power telescopic rod 6 is fixed to the bottom support plate 31. The bottom support plate 31 is slidably inserted between the two limiting side plates 5. The power telescopic rod 6 is an electric telescopic rod that controls the bottom support plate 31 to move up and down.

[0045] The transmission mechanism 7 includes two magnetically shielded gears 71 and two transmission gear plates 72. The two magnetically shielded gears 71 are coaxially mounted with both ends of the conveyor roller 23 near the material control mechanism 3. The magnetically shielded gears 71 rotate relative to the conveyor roller 23. Multiple circumferentially evenly distributed magnetic attracting rods 75 are fixedly mounted on the inner ring surface of the magnetically shielded gears 71. Magnetic attracting rods 76 are provided on the inner side of the magnetically shielded gears 71 and are mounted on the surface of the corresponding conveyor roller 23. When the conveyor roller 23 rotates, the magnetic attraction force generated by the magnetic attracting rods 76 on the magnetic attracting rods 75 drives the magnetically shielded gears 71 to rotate. The magnetic attraction between the magnetic attracting rods 76 and the magnetic attracting rods 75 is of a certain magnitude. To ensure the stability of the attraction between the magnetic rod 76 and the magnetic rod 75, multiple magnetic rods 76 and 75 are provided to provide sufficient traction force for operation of the equipment. When the transmission tooth plate 72 cannot move, the magnetic rod 76 rotates relative to the magnetic rod 75, and the magnetic isolation gear 71 rotates relative to the transmission roller 23. The material of the magnetic isolation gear 71 can isolate the magnetic force inside. The two transmission tooth plates 72 mesh with the upper side of the two magnetic isolation gears 71 respectively. The two side frames 21 are laterally slidably connected to the movable frame 73 on the side away from each other. The two transmission tooth plates 72 are fixed to the two movable frames 73 respectively.

[0046] It should be noted that the magnetic isolation gear 71 is made of insulating material, which can isolate the magnetism of the magnetic attracting rod 76 and the magnetic attracting rod 75 from the outside, so as to avoid the magnetic attracting rod 76 and the magnetic isolation gear 71 from affecting the conveying operation. In addition, the magnetic attracting rod 76 and the magnetic attracting rod 75 are permanent magnets, and there is a threshold for separating the magnetic attracting rod 76 and the magnetic attracting rod 75 from each other, and the threshold is N.

[0047] The transmission between the magnetic shielding gear 71 and the transmission gear plate 72 can push the material plate out of the material box through the auxiliary pusher 4. The two side frames 21 are fixed with horizontal telescopic rods 211 on opposite sides. The telescopic ends of the two horizontal telescopic rods 211 are fixed to the two moving frames 73 respectively. The horizontal telescopic rods 211 limit the movement range of the moving frames 73 and the auxiliary pusher 4. When the conveyor roller 23 rotates in both directions, it drives the two connected magnetic shielding gears 71 to rotate synchronously. When the magnetic shielding gear 71 rotates, it drives the transmission gear plate 72, the moving frame 73 and the auxiliary pusher 4 to move through the transmission between it and the transmission gear plate 72. When the horizontal telescopic rod 211 reaches the maximum extension and maximum compression, the magnetic rod 76 exceeds the threshold N relative to the magnetic attracting rod 75 under the action of external force. The magnetic rod 76 will rotate relative to the magnetic attracting rod 75, and the magnetic shielding gear 71 will idle relative to the conveyor roller 23, so that the conveyor roller 23 can continue to rotate without jamming.

[0048] If the material plate gets stuck or there are foreign objects during the conveying process, causing the material plate to be unable to move, the magnetic isolation gear 71 will rotate relative to the conveying roller 23, thereby stopping the moving block 41 from moving, thus avoiding damage to the material plate and greatly improving the stability of the operation.

[0049] Two clamping frames 32 are each provided with a side positioning plate 321 on one side away from each other. The other ends of the two side positioning plates 321 are bent close to each other. The side positioning plate 321 is provided with a long groove 322 at the end near the corresponding clamping frame 32. The long groove 322 is provided with a bolt rod. The bolt rod is threaded to the adjacent clamping frame 32. Loosening the bolt rod allows it to slide in the long groove 322, which can control the distance between the bent part of the side positioning plate 321 and the clamping frame 32. When the material box is placed, it is placed in the space between the bent part of the side positioning plate 321 and the conveyor belt 22, so that the bent part of the side positioning plate 321 contacts the end face of the material box.

[0050] The movable frame 73 has two telescopic parts, which are fixed by bolts. When the control side positioning plate 321 moves relative to the clamping frame 32, the bolts are loosened to change the length of the movable frame 73 accordingly.

[0051] The other ends of the two movable frames 73 are fixed by connecting plates 74, and the middle part of the side of the connecting plate 74 near the side frame 21 is fixed to the auxiliary push frame 4.

[0052] Two side frames 21 are fixed with an extension sliding plate 212 near the bottom support plate 31. The upper surface of the extension sliding plate 212 is flush with the upper surface of the conveyor belt 22. The end of the extension sliding plate 212 away from the conveyor belt 22 is an inclined surface that slopes downward. When the material plate is pushed out of the material box, the material plate moves to the upper side of the conveyor belt 22 through the extension sliding plate 212.

[0053] An upright plate 213 is fixed to the bottom surface of the extended sliding plate 212. The lower end of the upright plate 213 slides through the upper surface of the bottom support plate 31. One end of the upright plate 213 is located on the lower side of the bottom support plate 31 and is fixed to the upper surface of the support frame 1. After the material box is fixed, the upright plate 213 contacts the end face of the material box. As the material box moves up and down with the bottom support plate 31, the upright plate 213 blocks the end face of the material plate on the lower side of the extended sliding plate 212. When the material box moves up and down, the material plate on the lower side of the conveyor belt 22 will not move out of the material box due to vibration, so that the material plate will not slide out and collide with the conveyor belt 22 when the material box moves upward.

[0054] A movable block 41 is slidably inserted into one end of the auxiliary pusher 4 away from the connecting plate 74. A sleeve rod 42 connected to the movable block 41 is provided inside the auxiliary pusher 4. A push gear 44 is rotatably installed inside the connecting plate 74. An elastic element 47 is connected to the side of the sleeve rod 42 near the movable block 41. The elastic element 47 is preferably a spring. A positioning block 48 that slides inside the sleeve rod 42 is fixed at the other end of the elastic element 47. A push tooth plate 43 that penetrates the sleeve rod 42 is fixed at the other side of the positioning block 48. The other end of the push tooth plate 43 slides through the outside of the connecting plate 74 and meshes with the push gear 44. Trigger elements are provided at both ends of the push gear 44.

[0055] The trigger includes an extension gear 45. Both ends of the push gear 44 are coaxially fixed with extension gears 45. Both extension gears 45 have extension tooth plates 46 meshing on their upper sides. The connecting plate 74 is slidably sleeved on the outer surface of the two extension tooth plates 46. The two extension tooth plates 46 are located at one end outside the connecting plate 74 and are elastically connected to the connecting plate 74. They are preferably elastic telescopic rods, which have the tendency to drive the extension tooth plates 46 to mesh with the extension gears 45, thereby driving the push gear 44 to drive the push tooth plate 43 to move. The two extension tooth plates 46 correspond to the front and rear sides of the material box respectively.

[0056] In order to ensure that the travel of the push gear plate 43 is sufficient to move the movable block 41 to the predetermined position, the tooth diameter of the push gear 44 is smaller than that of the extension gear 45. Thus, when the extension gear 45 rotates one revolution, the push gear 44 also rotates one revolution, and the travel of the movable block 41 is greater than the travel of the extension gear plate 46.

[0057] It should be noted that the extended tooth plate 46 is located above the extended gear 45, and the push tooth plate 43 is located below the push gear 44. Other layout options can also be selected according to actual needs.

[0058] When the connecting plate 74 approaches the material box, it drives the auxiliary pusher 4 to push the material plate in the material box to move. During this process, the extended toothed plate 46 contacts the material box. Under the obstruction of the material box, the extended toothed plate 46 moves relative to the connecting plate 74. The extended toothed plate 46 and the extended gear 45 drive the push gear 44 to rotate, which in turn drives the push toothed plate 43 to move. The push toothed plate 43 pushes the elastic element 47 through the positioning block 48, and then pushes the sleeve rod 42 to gradually extend from the auxiliary pusher 4, so that the movable block 41 moves away from the connecting plate 74 and flexibly pushes the material plate to fall stably into the effective area of ​​the conveyor belt 22.

[0059] The forward rotation of the conveyor belt 22 drives the auxiliary pusher 4 and the sleeve rod 42 to push out the material plate. The reverse rotation of the conveyor belt 22 drives the auxiliary pusher 4 and the sleeve rod 42 to retract and reset, which will not obstruct the movement of the material plate in the material box. The magnetic attraction between the magnetic rod 76 and the magnetic attracting rod 75 meets the above-mentioned motion requirements.

[0060] Working principle: When the conveyor belt mechanism 2 is stationary, the auxiliary pusher 4 is located at the initial position away from the material box. The material box is loaded with multiple material plates. The power telescopic rod 6 pushes the bottom support plate 31 to rise and fall, so that the material box is aligned with the extension slide plate 212 and the auxiliary pusher 4 layer by layer. At this time, the magnetic rod 76 and the magnetic attracting rod 75 attract each other and stick to each other under the action of magnetic force. When the motor starts and drives the conveyor roller 23 to rotate, it drives the magnetic isolation gear 71 to rotate. The transmission tooth plate 72 that meshes with the magnetic isolation gear 71 is translated, and then drives the clamping frame 32 to move towards each other. The movable block 41 at the end of the auxiliary pusher 4 contacts and pushes the material plate.

[0061] During the advancement process, the material box block triggers the extension toothed plate 46 to move backward, driving the extension gear 45 to drive the push gear 44 to rotate. Since the push gear 44 and the extension gear 45 are relatively fixed, the push gear 44 drives the push toothed plate 43 to move forward. The movement of the push toothed plate 43 drives the positioning block 48 to move, and the elastic element 47 is compressed and stored, thereby driving the movable block 41 to move forward, removing the material plate from the material box and smoothly transitioning it to the conveyor belt 22 through the inner extension sliding plate 212.

[0062] During this process, the moving frame 73 and the connecting plate 74 are U-shaped. Since the material box is located between the two moving frames 73, the connecting plate 74 will come into contact with the material box during the movement of the moving frame 73 and the connecting plate 74. At this time, the entire moving frame 73, the connecting plate 74 and the transmission gear plate 72 will be subjected to force. When the force reaches the threshold N, the magnetic rod 76 and the magnetic rod 75 will move relative to each other and the magnetic rod 76 and the magnetic rod 75 will separate. The motor continues to rotate and the conveyor belt 22 conveys the material plate. Since the magnetic rod 76 and the magnetic rod 75 will separate under the action of external force, the conveyor roller 23 will rotate relative to the magnetic isolation gear 71.

[0063] The conveyor belt 22 transports the material plate to the dispensing station. After completing the conveying operation, it reverses to push the material plate back to its original position in the material box. When the conveyor roller 23 reverses, the external force on the magnetic rod 76 and the magnetic attracting rod 75 is released. The magnetic rod 76 and the magnetic attracting rod 75 attract each other and stick together. The conveyor roller 23 can drive the magnetic isolation gear 71 to rotate. The magnetic isolation gear 71 drives the auxiliary pusher 4 to retract. The sleeve rod 42 resets itself by pushing the toothed plate 43 and using elastic potential energy until the entire moving frame 73, the connecting plate 74 and the transmission toothed plate 72 are reset and the material plate is in the initial position. Then the power telescopic rod 6 drives the material box to rise to the position of the next material plate, thus completing one process operation. This process is repeated to complete the operation.
