Description

Technical Field

[0001] This invention relates to the field of TEC chip welding technology, and more specifically, to a TEC double-sided welding device. Background Technology

[0002] TEC is short for thermoelectric cooler, a solid-state refrigeration technology based on the Peltier effect of thermoelectric materials: when two different conductors form a circuit, if a direct current is applied to the circuit, one node in the circuit will release heat, while the other node will cool; if the current direction is reversed, the heat flow direction will also be reversed. The cooling capacity of a single thermoelectric material grain is limited, and TEC is generally composed of a dozen to dozens of grains combined with a thermistor and control current direction. TEC can both cool and heat, achieving temperature control stability better than 0.1℃.

[0003] The existing TEC chip manufacturing process requires multiple steps to complete the soldering of the TEC chip. First, the workers snap the TEC chips together, then place them on a heating table for heating and soldering, and then place them on a cooling table for cooling, thus completing the double-sided soldering of the TEC chip. However, the above steps require the workers to constantly transfer the products, which increases the number of work steps and further increases the processing time of the TEC chip, thereby reducing the processing efficiency of the TEC chip.

Detailed Implementation

[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.

[0038] Reference Figure 1-11 A TEC double-sided welding device includes a control cabinet 1, wherein, notably, the control cabinet 1 is equipped with a controller, and a control panel is provided on one side of the control cabinet 1 to further facilitate the operation of the relevant components of the device by the operator.

[0039] Meanwhile, the control cabinet 1 is equipped with an electric push rod, and the upper end of the electric push rod is connected to an ejector assembly 27, which is a placement plate. This allows the staff to conveniently place the sample. When placing the sample, the staff can first place the sample into two placement platforms with grooves, then fasten the two placement platforms together, and then place the placement platform onto the placement plate. At the same time, the staff can start the electric push rod through the controller, which will cause the ejector assembly 27 to move upward, further moving the sample to the appropriate position. It is worth noting that the baffle 26 can play a protective role, thereby preventing other parts from touching the sample and further preventing the sample from moving.

[0040] Meanwhile, a support plate 9 is fixedly connected to the upper end of the control cabinet 1, and a vertical plate 14 is fixedly connected to the support plate 9. A second electric telescopic rod 15 is fixedly connected to the vertical plate 14. It is worth noting that one end of the second electric telescopic rod 15 is connected to a push plate 16. It is worth noting that the push plate 16 is composed of rectangular blocks and triangular blocks. After the sample is moved to the appropriate position, the operator can start the electric telescopic rod 15 through the controller, so that the push plate 16 can be moved to one side, and the sample can be moved to the appropriate position.

[0041] Meanwhile, a protective cover 2 is fixedly connected to the upper end of the control cabinet 1. The protective cover 2 is made of transparent material, which allows staff to easily observe the operation of the internal components. A pusher 4 is fixedly connected to the input end of the protective cover 2. The pusher 4 is essentially an electric push rod, which can push the sample to the appropriate position.

[0042] The control cabinet 4 is fixedly connected to the preheating component 6. It is worth noting that the preheating component 6 is divided into two parts. One part is fixed on the control cabinet 1, and the other part is located above. At the same time, the pusher plate 16 can push the sample between the preheating components 6. Then, when the pusher 4 is working, it can push the sample into the heating component 7.

[0043] It is particularly noteworthy that the heating method of the preheating component 6 is electric heating, which can further preheat the sample. At the same time, multiple support rods 10 are fixedly connected to the upper end of the support plate 9, and the upper ends of the multiple support rods 10 are fixedly connected to the same fixed plate 11. A first electric telescopic rod 12 is installed through the fixed plate 11, and multiple connecting rods 13 are fixedly connected to the lower end of the first electric telescopic rod 12. The lower end of the connecting rod 13 is connected to a horizontal plate, and the lower end of the horizontal plate is connected to a part of the preheating component 6. This allows a part of the preheating component 6 to move accordingly, and further allows the sample to be properly placed between the preheating components 6.

[0044] After the preheating component 6 has finished heating the sample, the pusher 4 can push the sample to move it into the heating component. It is worth noting that the upper end of the control cabinet 1 is fixedly connected to the placement seat 25, and the placement seat 25 is equipped with the heating component 7. The heating component 7 is divided into another heating cover 701. One heating cover 701 is connected to the placement seat 25. Electromagnetic heating components 702 are fixedly connected to both heating covers 701. The other heating cover 701 is equipped with a movable protective cover 703. The other protective cover 703 has a notch 704. It is worth noting that the protective cover 703 can maintain the temperature, thereby avoiding temperature loss. It is worth noting that only one heating cover 701 has a protective cover 703. The heating cover 701 connected to the placement seat 25 does not have a protective cover 703, but the heating cover 701 connected to the placement seat 25 is connected to the electromagnetic heating component 702. The electromagnetic heating component 702 is at the same level as the heating cover 703, so that the sample can move normally.

[0045] Furthermore, each of the two heating covers 701 is provided with two first sliding grooves 705, and electromagnets 706 are fixedly connected to the inner sidewalls of the multiple first sliding grooves 705. Magnetic blocks 707 are slidably connected in the multiple first sliding grooves 705, and the multiple magnetic blocks 707 are respectively connected to multiple protective covers 703. It is particularly noteworthy that when the electromagnets 706 work, the magnetic blocks 707 can move accordingly, thereby enabling the protective covers 703 to move accordingly.

[0046] The first slide groove 705 has two symmetrical second slide grooves 708 on its side wall. Each of the two second slide grooves 708 is slidably connected to a slider 709. The two sliders 709 are respectively connected to a magnetic block 707. A retraction spring 710 is fixedly connected to the magnetic block 707, and one end of the retraction spring 710 is connected to the heating cover 701. When the electromagnet 706 is not working, the heating cover 701 can be reset with the assistance of the retraction spring 710. With the assistance of the second slide grooves 708 and the sliders 709, the protective cover 703 can move normally.

[0047] The control cabinet 1 has a first vertical column 17 fixedly connected to its upper end, a first hydraulic rod 18 fixedly connected to the first vertical column 17, a first pressing rod 19 fixedly connected to the output end of the first hydraulic rod 18, a first pressure plate 20 fixedly connected to one end of the first pressing rod 19, and one end of the first pressure plate 20 connected to one of the heating covers 701. Therefore, when the operator activates the first hydraulic rod 18 and the electromagnet 706 via the controller, the heating cover 701 moves upward. With the assistance of the electromagnet 706, the protective cover 703 moves downward. With the assistance of the notch 704, the sample can be pushed through normally. Since the protective cover 703 is made of insulating material, heat loss is prevented, allowing the sample to be heated and welded on both sides.

[0048] It is also worth noting that a second vertical column 21 is fixedly connected to the control cabinet 1, and a second hydraulic rod 22 is fixedly connected to the second vertical column 21. One end of the second hydraulic rod 22 is connected to a second top pressure rod 23, and one end of the second top pressure rod 22 is connected to a second pressure plate 24. The second pressure plate 24 is connected to one of the cooling blocks, thereby enabling one of the cooling blocks to move normally.

[0049] The cooling assembly 8 includes two cooling blocks. Notably, the cooling blocks are connected to an external air-cooled source, and the exhaust end of the protective cover 2 is fixedly connected to an intake pipe 3. The intake pipe 3 can draw back gas, thus preventing gas accumulation in the control cabinet 1. Simultaneously, when cold air is introduced into the cooling blocks, their temperature decreases, further reducing the product temperature. Each cooling block has two first ventilation channels 801 and two second ventilation channels 802. Multiple first branch channels 803 and multiple second branch channels 804 are provided between the two first ventilation channels 801 and the two second ventilation channels 802. Notably... The inclination direction of the multiple first branch channels 803 is the air inlet direction, while the inclination direction of the multiple second branch channels 804 is the opposite of the air inlet direction. With the assistance of the baffle 805, the airflow can enter the second branch channels 804, which can make the gas mixed, thereby accelerating the air circulation and further improving the heat dissipation effect of the device. Baffles 805 are fixedly connected to the side walls of the multiple second branch channels 804. At the same time, the protective cover 2 is equipped with a conveyor belt 5, which is located on one side of the cooling component 8. With the assistance of the pusher 4, the sample can be pushed onto the conveyor belt 5 to further complete the welding of the sample, thereby completing the overall processing of the device.

[0050] In this invention, when the operator needs to use this device, the operator can first place the sample directly on the ejector assembly 27, and then activate the electric push rod inside the control cabinet 1 through the controller, so that the ejector assembly 27 can be moved to a suitable position. At the same time, the controller activates the first electric telescopic rod 12, so that a part of the preheating assembly 6 can be moved upward. Simultaneously, the controller activates the second electric push rod, so that the push plate 16 can be moved, thereby moving the sample into the preheating assembly 6. Then the preheating assembly 6 works. After the sample is preheated, the controller activates the first hydraulic rod 18, so that the first pressure plate 20 can be moved upward, thereby moving one of the heating covers 701 upward. At the same time, the electromagnet 706 works, and with the assistance of the magnetic block 707, the protective cover 703 can be moved downward. Simultaneously, the controller activates the pusher 4, so that the sample can be pushed into the heating assembly 7. Then the controller can activate the electromagnetic heating assembly 702, so that the sample can be heated and welded.

[0051] After the heating and welding are completed, the sample originally in the heating assembly 7 can be pushed into the cooling assembly 8. At this time, the external cold source delivers cold air into the cooling block. With the assistance of the first branch 803 and the second branch 804, the sample can be cooled. After the sample is cooled, the pusher 4 continues to work, so that the sample originally in the heating assembly 7 can be pushed into the cooling assembly 8. The sample in the cooling assembly 8 can be pushed onto the conveyor belt 5, thereby completing the sample processing.

[0052] Finally, the following points should be noted: First, in the description of this application, it should be noted that, unless otherwise specified and limited, the terms "installation", "connection", and "linkage" should be interpreted broadly, and can be mechanical or electrical connections, or internal connections between two components, or direct connections.
