Description

Technical Field

[0001] The invention relates to the field of a bidirectional side-pull oxygen sensor chip positioning platform, and in particular belongs to a same-plane bidirectional side-pull oxygen sensor chip positioning platform. Background Art

[0002] Oxygen sensors are essential components for engines that use three-way catalytic converters to reduce exhaust pollution. In the process of manufacturing oxygen sensors, the chip is inserted into a ceramic seat with a through hole in the middle, and then the chip and the ceramic seat are spun as a whole to the inside of an outer protective cover with a hexagonal nut welded on the outside. At this time, an oxygen sensor chip positioning table is required to fix the chip and the ceramic seat as a whole, as well as the outer protective cover with a hexagonal nut welded on the outside, on the oxygen sensor chip positioning table, and then the chip and the ceramic seat are spun as a whole by an automatic spinning machine, and the chip ceramic seat is pressed as a whole into the inside of the outer protective cover with a hexagonal nut welded on the outside.

[0003] At present, the common oxygen sensor chip positioning platform has the following problems in actual use: 1. The positioning platform is an integrated platform plate, and the size of the loading holes on the platform plate is relatively large. One positioning platform can only position an outer protective cover of one size and model with a hexagonal nut welded on the outside, which cannot meet the actual use requirements of one positioning platform to position outer protective covers of different sizes and models with hexagonal nuts welded on the outside, which increases the production cost; 2. After the positioning platform is used continuously for a period of time, the platform plate of the positioning platform will be deformed due to the pressure of the automatic spinning machine, and the supporting feet of the original positioning platform cannot be adjusted, so that after the platform plate is deformed, the positioning platform can only be scrapped as a whole. At the same time, the positioning table does not have a horizontal infrared emitting and receiving device. The deformation of the platform plate of the positioning table cannot be adjusted and detected, and it cannot be sensed more accurately. It is often the case that the positioning table with a deformed platform plate is used to continue spinning production, so that the semi-finished oxygen sensor products produced are unqualified due to the chip and the ceramic seat not being spun in place as a whole, resulting in a large number of semi-finished products being reworked; 3. There is no two-way side-pull stage. It is impossible to push and pull out part of the two-way side-pull stage during continuous spinning production to load and unload other chip ceramic seats as a whole and the outer protective cover assembly with hexagonal nuts welded on the outside, and it is impossible to realize spinning production and product loading and unloading at the same time. For this reason, we have developed and manufactured a coplanar two-way side-pull oxygen sensor chip positioning table. Summary of the invention

[0004] The present invention provides a same-plane bidirectional side-pull oxygen sensor chip positioning platform, which solves the problems mentioned in the above background technology through the overall research and development design of the support beam frame, positioning rubber suction strip, infrared horizontal transmitter, induction receiver, alarm, left and right platform plates, handles, bidirectional side-pull loading platform, wear-resistant support feet, gripper and positioning plug-in parts. At the same time, the present invention can perform overall control spinning positioning for oxygen sensor chips of different models and sizes under the condition of ensuring the same horizontal plane height, ensuring that the spinning positioning of oxygen sensor chips with hexagonal nuts of different models and sizes is consistent, stable in positioning, adjustable in height, and easy to load and unload, and is suitable for promotion and use when spinning and packaging oxygen sensor chips.

[0005] The technical solution adopted by the present invention is as follows:

[0006] A same-plane bidirectional side-pull oxygen sensor chip positioning platform, characterized in that it includes a support beam frame, a positioning rubber suction strip, an infrared horizontal transmitter, an induction receiver, an alarm, left and right platform plates, a handle, a bidirectional side-pull loading platform, wear-resistant support feet, a gripper and a positioning plug-in component. The left and right platform plates are fixedly installed on the support beam frame, the support beam frame has an upper top beam frame and support feet, the support feet are installed at the four lower corners of the upper top beam frame, the upper top beam frame of the support beam frame has a groove around the outer side, the positioning rubber suction strip is embedded and fixed in the groove on the outer side of the back beam in the upper top beam frame, the groove on the outer side of the front beam in the upper top beam frame has a section of semi-sunk hole, and the positioning plug-in component is installed in the semi-sunk hole. The positioning card can be pushed right to lock or pushed left to release in the semi-counterfeit hole. The handle is fixedly installed on the outer side of the left and right sides of the supporting beam. The two-way side-pull loading platform is push-pull and embedded between the left and right platform plates. The wear-resistant support feet are installed under the bottom surface of the two-way side-pull loading platform. The gripper is installed on the outer front side of the two-way side-pull loading platform. There are positioning loading holes on the left and right platform plates and the two-way side-pull loading platform. The infrared horizontal transmitter is horizontally installed on the inner side of the supporting foot of the supporting beam, and the sensing receiver is horizontally installed on the inner side of the wear-resistant support foot of the two-way side-pull loading platform. The installation position of the sensing receiver corresponds to the infrared horizontal transmitter, and the alarm is connected to the sensing receiver.

[0007] Furthermore, the upper horizontal plane of the two-way side-pull loading platform and the upper horizontal planes of the left and right platform plates are located on the same plane.

[0008] Furthermore, the two-way side-pull loading platform has external bosses on its left and right side surfaces, and the inner side surfaces of the left and right platform plates have internal grooves. The external bosses of the two-way side-pull loading platform match the inner grooves of the left and right platform plates, and the external bosses of the two-way side-pull loading platform can perform inward and outward pushing and pulling movements within the inner grooves of the left and right platform plates.

[0009] Furthermore, the wear-resistant supporting feet and the supporting beam frame have tendon blocks at the bottom of the supporting feet, and the tendon blocks can be adjusted up and down at the bottom of the supporting feet through bolts.

[0010] Furthermore, the infrared horizontal transmitter installed on the inner side of the supporting feet of the supporting beam and the sensing receiver installed on the inner side of the wear-resistant supporting feet of the two-way side-pull loading platform are horizontally crossed and corresponded. The sensing receiver on the wear-resistant supporting feet at the bottom front of the two-way side-pull loading platform can receive the signal from the infrared horizontal transmitter installed on the left and right supporting feet at the bottom back of the supporting beam. The sensing receiver on the wear-resistant supporting feet at the bottom back of the two-way side-pull loading platform can receive the signal from the infrared horizontal transmitter installed on the left and right supporting feet at the bottom front of the supporting beam. When one of the sensing receivers cannot receive the signal sent by the infrared horizontal transmitter, the alarm will sound.

[0011] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0012] Through the overall R&D and design of the support beam, positioning rubber suction strip, infrared horizontal transmitter, induction receiver, alarm, left and right platform plates, handles, two-way side-pull loading platform, wear-resistant support feet, grippers and positioning plug-in parts, we have developed and manufactured a same-plane two-way side-pull oxygen sensor chip positioning table. It solves the following problems that exist in the actual use of ordinary oxygen sensor chip positioning tables: 1. The positioning tables are all one-piece platform plates, and the loading holes on the platform plates are of relative sizes. One positioning table can only position one type and size of outer protective cover with hexagonal nuts welded on the outside, which cannot meet the actual use requirements of one positioning table to position different types and sizes of outer protective covers with hexagonal nuts welded on the outside, which increases the production cost; 2. After a period of continuous use, the platform plate of the positioning table will be deformed due to the pressure of the automatic spinning machine, and the original positioning table's support feet cannot be adjusted, so after the platform plate is deformed, the positioning table can only be scrapped as a whole. At the same time, the positioning table does not have a horizontal infrared transmitting and receiving device. The degree of deformation of the platform plate of the positioning table cannot be adjusted and detected, and it cannot be sensed accurately. It is often the case that the positioning table with a deformed platform plate is used to continue the spinning production, resulting in the production of semi-finished oxygen sensors. The chips and ceramic seats are not spun in place, which leads to a large number of semi-finished products being reworked; 3. There is no two-way side-pull stage. During the continuous spinning production, other chip ceramic seats and the outer protective cover components with hexagonal nuts welded on the outside cannot be loaded and unloaded by pushing and pulling out part of the two-way side-pull stage, and the spinning production and product loading and unloading cannot be carried out simultaneously.

[0013] The present invention can perform overall controlled spinning positioning on oxygen sensor chips of different models and sizes under the condition of ensuring the same horizontal plane height, ensure that the spinning positioning of oxygen sensor chips with hexagonal nuts of different models and sizes has good consistency, stable positioning, adjustable height, and convenient loading and unloading, and is suitable for promotion and use in spinning packaging of oxygen sensor chips.

After the positioning platform has been used continuously for a period of time, the platform plate of the positioning platform will be deformed due to the pressure of the automatic spinning machine, and the original support foot 102 of the positioning platform cannot be adjusted, so that after the platform plate is deformed, the positioning platform can only be adjusted as a whole. Scrapped. At the same time, the positioning table does not have a horizontal infrared transmitting and receiving device. The degree of deformation of the platform plate of the positioning table cannot be adjusted and detected, and it cannot be sensed accurately.
