Description

Technical Field

[0001] This utility model relates to the technical field of die bonding equipment, specifically to die bonding equipment that facilitates material loading. Background Technology

[0002] Die-bonding equipment is a core piece of equipment in semiconductor packaging and LED manufacturing, primarily responsible for the "die bonding" step. It attaches tiny chips to a substrate, lead frame, or support using adhesive. The precision of this process directly impacts subsequent packaging quality, such as soldering reliability and heat dissipation performance. For example, utility model patent CN212786496U discloses a mobile multi-head die-bonding machine, including a base plate with casters fixedly connected to its bottom. A brake pad is hinged to one side of each caster. The die-bonding machine is fixedly connected to the top of the base plate, and a material rack is fixedly connected to its right side. This mobile multi-head placement machine utilizes the cooperation between slide bars on both sides of the worktable and the external carriages of the slide bars to facilitate the forward and backward movement of the placement head. A slide rail at the bottom of the crossbar, with a slider slidably connected to the outside of the slide rail, facilitates the left and right movement of the placement head. An electric push rod moves the placement head up and down, allowing for rapid forward, backward, left, and right movement to process multiple items for placement, achieving a high placement speed and effectively solving the problem of placement head immobility affecting placement efficiency. However, this device still has some shortcomings: it is inconvenient to load materials during placement, and the device is not easy to change workstations, thus affecting placement efficiency. Therefore, improvements are needed. Utility Model Content

A connecting rod is fixedly connected to the surface of the slip ring, and a pin is fixedly connected to the lower end of the connecting rod. The pin is slidably connected to the base. The motor drives the semi-toothed ring to rotate, which, in conjunction with the gear, causes the support shaft to rotate the pallet, thereby enabling the device to switch workstations for easy placement operations. Simultaneously, the relative sliding of the inclined plate and the baffle allows the top plate to eject the workpiece, making workpiece replacement more convenient.

[0007] Preferably, a guide block is fixedly connected inside the slip ring, and the guide block is slidably connected to the support shaft. By providing the guide block, rotation of the slip ring and the support shaft is prevented.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Please see Figures 1-3 A die bonding and surface mount device for easy loading includes a base 1, a conversion mechanism 2 on the base 1, a support plate 3 on the conversion mechanism 2, a loading mechanism 4 on the base 1, a bracket 5 fixedly connected to the upper end of the base 1, a cylinder 6 fixedly installed in the middle of the upper end of the bracket 5, the cylinder rod of the cylinder 6 passing through the bracket 5 and slidably connected to the bracket 5, a pressure head 7 fixedly connected to the end of the cylinder rod of the cylinder 6, a top plate 8 slidably connected inside the support plate 3, a top rod 9 fixedly connected to the lower end of the top plate 8, the top rod 9 slidably connected to the support plate 3, a ramp 10 fixedly connected to the lower end of the top rod 9, and a baffle 11 fixedly connected to the upper end of the base 1, the baffle 11 slidably connected to the ramp 10. By setting the baffle 11, the ramp 10 can be easily moved upward.

[0021] Please see Figures 1-4The conversion mechanism 2 includes a support shaft 21. The support shaft 21 is mounted inside the base 1 via bearings. A gear 22 is fixedly connected to the lower end of the support shaft 21. A motor 23 is fixedly mounted on the upper end of the base 1. The shaft of the motor 23 passes through the base 1 and is rotatably connected to it. A semi-tooth ring 24 is fixedly connected to the lower end of the motor 23's shaft. A slip ring 25 is slidably connected to the outer side of the support shaft 21. A guide block is fixedly connected inside the slip ring 25. The guide block and the support shaft 21 are slidably connected. By setting the guide block, rotation of the slip ring 25 and the support shaft 21 is prevented. A spring 26 is provided on the outer side of the support shaft 21. One end of the spring 26 is fixedly connected to the support plate 3, and the other end of the spring 26 is fixedly connected to the slip ring 25. Next, by setting spring 26, the slip ring 25 is elastically pressed down. A connecting rod 27 is fixedly connected to the surface of the slip ring 25. A pin 28 is fixedly connected to the lower end of the connecting rod 27. The pin 28 is slidably connected to the base 1. A support ring 29 is fixedly connected to the upper end of the base 1. The support ring 29 contacts the tray 3. By setting the support ring 29, the tray 3 is elastically supported. The motor 23 drives the half-tooth ring 24 to rotate and engages with the gear 22, thereby causing the support shaft 21 to drive the tray 3 to rotate, thereby enabling the device to switch positions and facilitate the patching operation. At the same time, by sliding the inclined plate 10 and the baffle 11 relative to each other, the top plate 8 can push out the workpiece, making workpiece replacement more convenient.

[0022] Please see Figures 1-3 The feeding mechanism 4 includes a screw 41. The screw 41 is installed inside the base 1 through a bearing. The outer side of the screw 41 is connected to a connecting plate 42 through a thread. The connecting plate 42 is slidably connected to a guide rod 43. The guide rod 43 is fixedly connected to the base 1. The surface of the connecting plate 42 is fixedly connected to a discharge cylinder 44. By rotating the screw 41 and the connecting plate 42 to make threaded movement, the connecting plate 42 drives the discharge cylinder 44 to move, thereby making the device convenient for feeding parts of different thicknesses.

[0023] The specific implementation process of this utility model is as follows: In use, the part is placed into the feeding cylinder 44, and the motor 23 is started. The motor 23 drives the rotating shaft to rotate, which in turn drives the half-tooth ring 24 to rotate. The half-tooth ring 24 rotates until the teeth disengage from the gear 22, thereby causing the gear 22 to rotate. The gear 22 drives the support shaft 21 to rotate, which in turn drives the support plate 3 to rotate. The support shaft 21 drives the slip ring 25 to rotate, which in turn drives the connecting rod 27 to move. This causes the pin 28 to move and become misaligned with the insertion hole on the base 1 at the current position, thereby causing the pin 28 to move upward. This causes the connecting rod 27 to drive the slip ring 25 to move upward, thereby compressing the spring 26 until the half-tooth ring 24 rotates until it disengages from the gear 22, thereby stopping the rotation of the support plate 3. After the workstation transition is completed, the spring 26 resets, causing the slip ring 25 to reset. This allows the slip ring 25 to drive the pin 28 into the corresponding insertion hole via the connecting rod 27. The motor 23 drives the half-tooth ring 24 to rotate and engages with the gear 22, which in turn causes the support shaft 21 to drive the tray 3 to rotate. This allows the device to transition to a different workstation, facilitating the placement operation. Simultaneously, the relative sliding of the inclined plate 10 and the baffle 11 allows the top plate 8 to eject the workpiece, making workpiece replacement more convenient. During this process, the unloading cylinder 44 enters the tray 3. By rotating the screw 41 and the connecting plate 42, the screw 41 moves in a threaded motion, causing the connecting plate 42 to move the unloading cylinder 44. This makes it easier for the device to load parts of different thicknesses.
