Description

Technical Field

[0001] The present invention relates to the technical field of sensor chip welding, and in particular to a sensor chip welding device. Background Art

[0002] The sensor chip is a highly integrated component, usually composed of three core parts: sensor, signal conditioning circuit and data processing unit. As the gateway to information, the sensor is responsible for capturing various information from the outside world and converting it into electrical signals. Next, the signal conditioning circuit will perform a series of sophisticated processing on these raw electrical signals, including amplification, filtering and calibration, to ensure the accuracy and stability of the signal. Finally, the data processing unit takes over the baton, further converts the conditioned signal into a digital format, and applies relevant algorithms for in-depth analysis to extract valuable information.

[0003] In the production process of sensor chips, the welding of sensor core pins is a crucial link. Traditionally, the core pins need to be accurately inserted into the sensor chip first, and then tin powder is evenly applied on the contact surface between the core pins and the chip. By precisely controlling the heating temperature, the tin powder will melt quickly, thereby firmly welding the core pins to the chip. However, there are often some problems in this process.

[0004] First, the manual operation of placing the core pin limiter on the chip and moving it to the welding equipment is not only inefficient, but also prone to misalignment. This misalignment may cause poor welding, which in turn affects the performance of the sensor. Secondly, even if the core pin is correctly placed on the chip, the welding equipment may have uneven temperature distribution during the heating process. This will cause the tin powder to not melt fully, making it impossible for the core pin to form a strong welding connection with the chip. This welding defect will also have a serious impact on the subsequent use of the sensor. Summary of the invention

[0072] The guide plate 70321 is movably arranged in the hollow frame 7031 , the driven plate 70322 is arranged on the top wall of the guide plate 70321 , and the buffer components 70323 are multiple groups, and the multiple groups of buffer components 70323 are linearly arrayed on the guide plate 70321 .

[0073] It should be noted that the guide member 7032 is a 7-shaped guide plate frame. After the guide member 7032 pushes the movable base plate 6021 to move to the end point, the movable base plate 6021 stops moving and the guide member 7032 is affected by the inclined end surface. The guide plate 70321 moves downward, and the guide member 7032 gradually separates from the movable base plate 6021, realizing automatic feeding and blocking.

[0074] In one embodiment of the present invention, Fig. 9 As shown, the fastening mechanism 708 includes a partition 7081 and an abutment member 7082 .

[0075] The partition 7081 is disposed on the supporting substrate 701 , and the abutting member 7082 is disposed on the partition 7081 .

[0076] The abutment member 7082 includes a hollow sleeve 70821 , a movable shaft 70822 , a telescopic member 70823 and an abutment plate 70824 .

[0077] Among them, the hollow sleeve 70821 is set on the partition 7081, one end of the movable shaft 70822 is movably set in the hollow sleeve 70821, the telescopic component 70823 is sleeved on the movable shaft 70822; and the abutment plate 70824 is set at the other end of the movable shaft 70822.

[0078] It should be noted that the partition 7081 is installed on the supporting substrate 701, and the movable shaft 70822 drives the abutment plate 70824 to abut against the mounting base 704 through the telescopic component 70823, thereby limiting and fixing the mounting base 704. The telescopic component 70823 is a telescopic spring.

[0079] Specifically, the steps of welding the sensor's core pins and chip together are:

[0080] The steps of adding the mixture of tin powder and gunpowder powder to the sensor chip are as follows: tin powder and gunpowder powder are respectively filled into the storage box 1 202 and the storage box 2 203, and the driving component 3 402 is operated. When the driving component 3 402 is operated, the rotating shaft 403 is driven to rotate, and the baffle plate 404 rotates and moves from below the storage box 1 202 and the storage box 2 203 during the rotation process. During the rotation process, the discharge port below the storage box 1 202 and the storage box 2 203 is opened, so that the tin powder and gunpowder powder fall into the inner cover shell 50 in proportion. During the operation of the driving component 3 402, the driven shaft 4051 and the stirring rod 4053 are synchronously driven to rotate, and the stirring rod 4053 and the conveying auger 4052 rotate, thereby stirring and mixing the tin powder and gunpowder powder falling into the inner cover shell 50.

[0081] At this time, the driving component 102 is operated. When the driving component 102 is operated, it drives the transmission shaft 103 to rotate. The rotation of the transmission shaft 103 drives the conveyor belt 104 to rotate, and the chip to be welded is placed in the mounting base 704. The mounting base 704 is mounted on the supporting substrate 701 through the fastening mechanism 708, and the supporting substrate 701 is inserted into the limiting groove 105 through the clamping shaft 702. The sensor chip moves synchronously with the supporting substrate 701 on the conveyor belt 104. During the movement of the sensor chip, the buffer mechanism 703 and the movable bottom plate 6021 are in contact and connected, thereby pushing the movable bottom plate 6021 to move in a limited manner. The movable bottom plate 6021 slides in a limited manner on the fixed baffle 601 through the limiting shaft rod 6023. During the limited movement of the movable bottom plate 6021, the discharge holes on the movable bottom plate 6021 and the baffle plate 2 6024 are pushed to align. At this time, the discharge hole is located directly above the powder cavity 705, and the mixed welding powder falls into the powder cavity 705. When the buffer mechanism 703 and the movable bottom plate 6021 are separated, they are reset by the reset component 603, and the mixed material no longer falls. The powder falling into the powder cavity 705 enters the sampling hole 707, and gunpowder powder is added to the ignition groove 706.

[0082] The steps of installing the core pin on the limit sensor are as follows: first, place the sensor core pin to be welded on the limit card plate 3023, and the limit card plate 3023 is embedded in the through hole 3022 through the fastening component 3024. The bottom plate 3021 moves in the limit position on the limit bracket 301, and moves to the bottom of the pressing plate 3033, and the driving component 2 3032 is operated. The driving component 2 3032 pushes the pressing plate 3033 to move downward, and the limit card plate 3023 with the core pin is pushed out of the through hole 3022 during the downward movement of the pressing plate 3033. The sensor chip with the mixed material moves synchronously with the conveyor belt 104. When the injection hole 707 moves to the bottom of the pressing plate 3033, the core pin is pressed into the injection hole 707, and the assembly of the core pin and the sensor chip is completed.

[0083] The welding steps are as follows: ignite the gunpowder powder to ignite the powder in the injection hole 707, melt the tin powder therein, and weld the core pin and the sensor chip together.

[0084] In summary, the sensor chip welding equipment of the embodiment of the present invention adopts a mixture of gunpowder powder and tin powder and adds them directly to the sensor chip, limits the connection between the core pin and the sensor chip, and uses the gunpowder powder to heat-melt the tin powder so that the core pin is directly welded to the chip and fixed together, which is more efficient and improves the welding yield rate.

A person skilled in the art may change, modify, replace and deform the above embodiments within the scope of the present invention.
