Description

Technical Field

[0001] This utility model relates to the field of sensor manufacturing technology, and more specifically, to a substrate pressing device for sensor manufacturing. Background Technology

[0002] In the field of sensor chip manufacturing, sensor chips, as miniature electronic devices that convert non-electrical quantities (such as temperature, pressure, light intensity, sound, etc.) into electrical quantities (such as voltage, current, resistance, etc.), play a key role in information detection, transmission, processing and control in various electronic devices. The chip substrate, as an important component of the sensor chip, carries the various components of the chip, and its quality and stability directly affect the performance and reliability of the sensor chip.

[0003] Currently, most chip substrates are die-cast using precision pressing equipment. However, after molding, traditional processes typically require workers to manually remove the die-cast chip substrate from the mold. Since this removal and placement operation must be performed at the die-casting location, and the die-casting area presents safety hazards, workers are prone to injuries such as pinching while manually operating in this environment. Therefore, we have made an improvement and proposed a precision pressing device for sensor substrate production. Utility Model Content

[0017] To enable those skilled in the art to better understand the present invention, the technical solutions of the present invention 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 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 should fall within the protection scope of the present invention.

[0018] It should be noted that, unless otherwise specified, the embodiments and features and technical solutions in the present invention can be combined with each other.

[0019] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0020] For an example, please refer to... Figures 1-4 A precision pressing device for sensor substrate production includes a precision pressing mechanism 1. The precision pressing mechanism 1 includes a base 101, a precision pressing structure 5 and a rotating shaft 2 on the base 101. The rotating shaft 2 is rotatably mounted on the top of the base 101 via bearings. A support member is provided on the top of the rotating shaft 2, and two lower molds 205 are mounted on the support member. When picking up or placing chip substrates, the corresponding support structure 5 can be rotated away from the die-casting area. This design effectively reduces the number of workers performing pick-up and place operations at the die-casting position, reduces the risk of safety accidents such as workers being pinched, and ensures the personal safety of workers. When picking up or placing chip substrates in one lower mold 205, the other lower mold 205 can simultaneously perform die-casting preparation work, realizing the parallel execution of die-casting and pick-up / placement operations, reducing equipment idle time, and improving the continuity of the production process.

[0021] Furthermore, the precision pressing structure includes multiple support seats 102 mounted on the top of the base 101. A first support plate 103 is fixedly connected between the tops of the multiple support seats 102. A first hydraulic cylinder 104 is mounted on the top of the first support plate 103. The bottom end of the first hydraulic cylinder 104 passes through the first support plate 103 and extends to the bottom of the first support plate 103 and is connected to a connecting seat 105. Several connecting rods 106 are connected to the bottom of the connecting seat 105. An upper mold 107 is connected between the bottom ends of the several connecting rods 106. The first hydraulic cylinder 104 can be supported by the cooperation of the support seats 102 and the first support plate 103. The first hydraulic cylinder 104 can drive the connecting seat 105, the connecting rods 106 and the upper mold 107 to rise and fall.

[0022] Furthermore, several uprights 108 are fixedly installed on the top of the connecting seat 105. The top of the uprights 108 passes through the first support plate 103 and extends above the first support plate 103. The uprights 108 can limit the lifting and lowering of the connecting seat 105 to improve the stability of the connecting seat 105 during the lifting and lowering process.

[0023] Furthermore, the support includes a connecting shaft 201 fixedly installed on the top of the rotating shaft 2, a connecting plate 202 fixedly connected to the top of the connecting shaft 201, a first support ring 203 fixedly connected between the two ends of the connecting plate 202, two lower molds 205 both installed on the top of the first support ring 203, and a second support ring 207 connected between the bottoms of the two lower molds 205. The rotating shaft 2, the connecting shaft 201, the connecting plate 202 and the first support ring 203 cooperate to support the lower molds 205, and the second support ring 207 can reinforce the two lower molds 205.

[0024] Furthermore, a limiting hole 4 is provided through the rotating shaft 2, and a fixing structure 3 is provided on the top of the base 101 to cooperate with the limiting hole 4.

[0025] Furthermore, the fixing structure 3 includes a fixing seat 301 installed on the top of the base 101. A cavity 302 is provided inside the fixing seat 301. A baffle 303 is slidably connected inside the cavity 302. A positioning rod 304 is fixedly inserted into the middle of the baffle 303. One end of the positioning rod 304 is inserted into the limiting hole 4, and the other end of the positioning rod 304 extends to the outside of the fixing seat 301. The two openings of the limiting hole 4 correspond to the positions of the two lower molds 205 respectively. The insertion of the positioning rod 304 into the limiting hole 4 can limit the rotation of the rotating shaft 2 to prevent the rotating shaft 2 from rotating, thereby aligning the upper mold 107 with the corresponding lower mold 205 during the precision pressing process.

[0026] Furthermore, a spring 305 is sleeved on the outer surface of the positioning rod 304. The spring 305 is located inside the cavity 302, and both ends of the spring 305 are in contact with the baffle 303 and the inner wall of the cavity 302, respectively. When the positioning rod 304 is pulled to separate from the limiting hole 4, the positioning rod 304 is released during the rotation of the rotating shaft 2. When the positioning rod 304 is aligned with the limiting hole 4, it will automatically insert into the limiting hole 4 under the action of the spring 305 and the baffle 303, so as to achieve positioning when the two lower molds 205 rotate.

[0027] Furthermore, a support structure 5 is provided on the top of the base 101. The support structure 5 is located below the second support ring 207 and can support the second support ring 207.

[0028] Furthermore, the support structure 5 includes a second hydraulic cylinder 501 installed on the top of the base 101. A second support plate 502 is installed on the top of the second hydraulic cylinder 501. The second support plate 502 is located below the second support ring 207. The second hydraulic cylinder 501 can drive the second support plate 502 to rise and fall. After the second support plate 502 rises, it contacts the bottom of the second support ring 207, which can support the second support ring 207 during the fine pressing process.

[0029] Furthermore, a number of limiting tubes 505 are installed on the top of the base 101. Limiting rods 504 are inserted into the inner wall of the limiting tubes 505. The top of the limiting rods 504 is connected to the bottom of the second support plate 502. The limiting tubes 505 and the limiting rods 504 cooperate with each other to limit the second support plate 502, thereby improving the stability of the second support plate 502 when it is raised or lowered.

[0030] The process of using the substrate precision pressing device for sensor production provided by this utility model is as follows: When rotating the lower mold 205 to switch its position, the second hydraulic cylinder 501 first drives the second support plate 502 to descend, then pulls the positioning rod 304 to separate the positioning rod 304 from the limiting hole 4, then rotates the second support ring 207 and releases the positioning rod 304. During the rotation, when the positioning rod 304 is aligned with the limiting hole 4, it will automatically insert into the limiting hole 4 under the force of the spring 305 and the baffle 303 to achieve positioning when the two lower molds 205 rotate. Then, the second support plate 502 rises under the drive of the second hydraulic cylinder 501 to support the lower mold 205, while the first hydraulic cylinder 104 drives the upper mold 107 to descend through the connecting seat 105 and the connecting rod 106 to cooperate with the lower mold 205 below the upper mold 107 for precision pressing. At this time, the operator can pick up and put down the substrate at the other lower mold 205.
