Technical Field

[0001] The utility model relates to the technical field of electronic devices, in particular to a pre-curing device after die bonding. Background Art

[0002] Electronic devices are the general term for electronic components and mechanical components, and are usually used in various electronic products and devices. With the gradual maturity of optical communication products, the TO package of optical devices has lower cost and relatively simpler process compared with the BOX package, and basically occupies the mainstream packaging application market of microelectronic devices.

[0003] In the existing die bonding process, after an electronic component is connected to a TO socket through glue, it is manually transferred to an oven for baking and curing. Since the glue is not cured during the transfer process, there is a risk of displacement of the electronic component. Therefore, a pre-curing device after die bonding is needed to pre-cure the glue of the electronic component. Summary of the Utility Model

[0004] The purpose of the utility model is to provide a pre-curing device after die bonding to solve the problem in the above background art that in the existing die bonding process, after an electronic component is connected to a TO socket through glue, it is manually transferred to an oven for baking and curing, and since the glue is not cured during the transfer process, there is a risk of displacement of the electronic component.

[0005] To solve the above technical problems, the utility model is realized through the following technical solutions:

[0006] The utility model is a pre-curing device after die bonding, including:

[0007] A pre-curing component, the pre-curing component includes a connecting rod, a group of conveyor belts, a group of roller rods, and a bi-axial motor;

[0008] The upper sides of the conveyor belts are respectively clamped on both sides of the top end of the connecting rod, and a bi-axial motor is arranged between the inner sides of one end of the conveyor belts. The output end of the bi-axial motor is fixed with a roller rod, and the middle of the outer surface of the roller rod is in belt transmission connection with one end of the conveyor belt.

[0009] Further, a group of heating rods are fixedly connected to one side of the connecting rod, and electric wires are fixedly connected to one side of each heating rod.

[0010] Further, a strip is placed between the top ends of the conveyor belts, and a material box is placed on the other side of the connecting rod.

[0011] Further, a group of clamping grooves are opened at the top end of the connecting rod, and a group of rollers are placed inside the clamping grooves.

[0014] Compared with the prior art, the advantages of the present utility model are as follows:

[0015] First, in the present utility model, in this device, an automatic die bonder places the strip of socket holders with the chips already pasted on the conveyor belt, and then the dual-axis motor starts to rotate. The dual-axis motor drives the conveyor belt to operate through the roller rods, so that the strip moves to the material box through the conveyor belt. During the movement of the strip, under the influence of the heating rod, the glue on the surface of the strip is pre-cured. Then, the pre-cured products in the material box are placed in the oven for baking and curing, which can effectively prevent the displacement of electronic components during the transfer process.

[0028] Please refer to Figures 1 - 5 As shown, this embodiment is a pre-curing device after die bonding, including:

[0029] A pre-curing assembly, which includes a connecting rod 11, a group of conveyor belts 12, a group of roller rods 13, and a double-shaft motor 14;

[0030] Above the conveyor belt 12, it is respectively clamped on both sides of the top end of the connecting rod 11. And between the inner sides of one end of the conveyor belt 12, a double-shaft motor 14 is arranged. The output end of the double-shaft motor 14 is fixed with a roller rod 13, and the middle part of the outer surface of the roller rod 13 is in belt transmission connection with one end of the conveyor belt 12;

[0031] The connecting rod 11 is used to place other components. There are two conveyor belts 12 in total. Above the conveyor belts 12, they are respectively clamped on the front side and the rear side of the top end of the connecting rod 11. The roller rod 13 is used for the transmission operation of the conveyor belt 12, and the double-shaft motor 14 is used to drive the roller rod 13 to rotate;

[0032] One side of the connecting rod 11 is fixedly connected with a group of heating rods 15, and one side of each heating rod 15 is fixedly connected with a wire 16;

[0033] The heating rods 15 are fixed on the front side of the connecting rod 11, and there are two heating rods 15 in total. The wires 16 are fixed to the right ends of the heating rods 15. The wires 16 are used to connect to an external power source to drive the heating rods 15 to generate heat, so as to cure the glue of the strip 111;

[0034] A strip 111 is placed between the top ends of the conveyor belts 12, and a strip box 17 is placed on the other side of the connecting rod 11;

[0035] The strip box 17 is used to place the transported strip 111, and the strip box 17 is used to be placed in an oven for heating and baking. The strip box 17 is placed on the right side of the connecting rod 11, and there is a distance between the two;

[0036] A set of card slots 18 are opened at the top end of the connecting rod 11, and a set of rollers 19 are placed inside the card slots 18;

[0037] The card slots 18 are opened at the front and rear sides of the top end of the connecting rod 11. There are two card slots 18 in total. The card slots 18 are used to place the rollers 19, and the rollers 19 are used to transport the strip 111;

[0038] Fixed shafts 20 penetrate through both sides of the roller 19, and the other ends of the fixed shafts 20 are fixedly connected to the inside of the card slots 18;

[0039] The fixed shafts 20 are provided to enable the rollers 19 to rotate. The rotating rollers 19 can be used to transport the strip 111. The fixed connection between the fixed shafts 20 and the card slots 18 supports and limits the rotation of the rollers 19;

[0040] The card slots 18 are all located on one side of the conveyor belt 12, and the wire 16 is connected to an external power source;

The wire 16 is connected to an external power source, so as to electrically drive the heating rod 15, making the heating rod 15 start to heat, so that the glue is pre-cured, avoiding the displacement of the strip 111 before entering the material box 17;

[0042] Working principle:

[0043] Electrically connect the components and the wire 16 to an external power source. After being powered on, the dual-shaft motor 14 drives the roller rods 13 on both sides to rotate together, and then the roller rods 13 drive the conveyor belt 12 to start operating;

[0044] Since the wire 16 is connected to the power source, the heating rod 15 is electrically driven to start heating. Then the staff places the strip 111 on the conveyor belt 12. The conveyor belt 12 and the rollers 19 in the card slots 18 act on the strip 111 together, making the strip 111 move and be transported on the connecting rod 11. At the same time, the outer heating rod 15 heats the inner strip 111, so that the glue on the surface of the strip 111 gradually cures during the movement, and the conveyor belt 12 transports the strip 111 into the material box 17;

[0045] When the material box 17 is full, then the staff can place the material box 17 in the baking oven to bake the material box 17;

[0046] The above steps can improve its own functionality.
