Description

Technical Field

[0001] This utility model relates to the field of electrode patch assembly technology, specifically to an electrode patch assembly fixture. Background Technology

[0002] The placement of electrode patches plays a crucial role in bioelectrical measurements. Proper electrode placement ensures accurate acquisition of bioelectrical signals and improves measurement reliability. Common electrode patches consist of a flexible backing, a transducer array, several supports, leads, and an adhesive layer. During assembly, the transducer array is first soldered to the leads. Then, the transducer array is adhered to the flexible backing. Next, the supports are adhered to the flexible backing in a manner that surrounds the transducer array. The adhesive layer is then placed over the supports and transducer array. Finally, release paper is applied to the outside of the adhesive layer for protection.

[0003] However, the assembly of electrode patches currently still relies on manual operation. The flexible backing is a soft fabric, and the assembly fixtures currently used cannot fix the flexible backing well, which makes the flexible backing prone to wrinkles. The assembly step of attaching the transducer array to the backing is inefficient, which affects the overall assembly efficiency and manufacturing cost of the product. Therefore, it does not meet the current needs. In response, we have proposed an electrode patch assembly fixture. Utility Model Content

[0004] The purpose of this utility model is to provide an electrode patch assembly fixture to solve the problems mentioned in the background art, such as the current assembly of electrode patches still relying on manual operation, the flexible backing being a soft fabric, the current assembly fixtures being unable to fix the flexible backing well, resulting in wrinkles on the flexible backing, and the low efficiency of the assembly step of pasting the transducer array onto the backing, which affects the overall assembly efficiency and manufacturing cost of the product.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an electrode patch assembly fixture, comprising a base and a cover plate. A square groove is provided on the upper surface of the base. Clamping mechanisms are movably mounted on both sides of the square groove via electric push rods. Each clamping mechanism includes strip plates. A strip groove is provided on one side of the outer surface of each of the two strip plates facing each other. A short shaft is provided on the inner side of the strip groove. Threaded rods are installed on both the front and rear faces of the short shafts. A threaded plate is fitted onto the outer surface of the threaded rods. A clamping plate is fixedly installed on the outer surface of the threaded plate. An air suction chamber is provided below the square groove. Multiple housings are evenly installed above the air suction chamber. The housings are connected to the square groove through multiple through holes. The housings are connected to the air suction chamber through connecting holes, and a one-way valve is installed inside the connecting holes. An air pump is installed on the outer surface of the base. Positioning holes are provided at the four corners of the upper surface of the base. Positioning posts are installed at the four corners of the lower surface of the cover plate. A through groove is provided on the upper surface of the cover plate.

[0006] Preferably, the positioning post corresponds one-to-one with the positioning hole, and the positioning post can be inserted into the inside of the positioning hole. A first magnet is installed on the lower end face of the positioning post, and a second magnet is installed on the upper end face of the positioning hole. The magnetic poles of the first magnet and the second magnet are opposite.

[0007] Preferably, there are three cover plates that match the base, and the through slots opened on the surface of the three cover plates are all of different sizes.

[0008] Preferably, the air pump is connected to the air intake chamber via a duct, and a rubber pad is fixedly connected to the opposite side of the outer surface of each pair of clamps by an adhesive.

[0009] Preferably, the thread directions of each pair of threaded rods are opposite, and a motor is mounted in front of the strip groove through the motor cavity.

[0010] Preferably, the output end of the motor is fixedly connected to the front end face of one of the threaded rods via a coupling, and the rear end face of the other threaded rod is rotatably connected to the inner wall of the strip groove via a bearing.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] 1. This utility model, by setting up a clamping mechanism, adjusts the position of the strip plate according to the size of the flexible backing by controlling the switch of the electric push rod, and then adjusts the position of the clamping plate by controlling the switch of the motor, placing the flexible backing inside the groove formed by the clamping plate and the strip plate. Then, by opening the switch of the one-way valve covered by the flexible backing and the switch of the air pump, negative pressure is generated in the air suction chamber, the corresponding connecting hole and the through hole, which can generate uniform suction force on all positions of the flexible backing placed inside the square groove. By using the cover plate with three sets of through slots of different sizes, transducer arrays of different sizes can be positioned and pasted. This utility model can fix flexible backings of different sizes, is not prone to wrinkles, and can position transducer arrays of different sizes, thus improving applicability.

[0020] Please see Figures 1 to 4This utility model provides an embodiment of an electrode patch assembly fixture, comprising a base 1 and a cover plate 2. A square groove 9 is provided on the upper surface of the base 1. Clamping mechanisms 8 are movably mounted on both sides of the square groove 9 via electric push rods 11. The clamping mechanism 8 includes strip plates 802. A strip groove 803 is provided on one opposite side of the outer surface of the two strip plates 802. A short shaft 804 is provided on the inner side of the strip groove 803. Threaded rods 805 are mounted on both the front and rear ends of the short shaft 804. A threaded plate 806 is sleeved on the outer surface of the threaded rod 805. A clamping plate 801 is fixedly installed on the outer surface of 06. An air suction chamber 10 is provided below the square groove 9. Multiple housings 12 are evenly installed above the air suction chamber 10. The housings 12 and the square groove 9 are connected through multiple through holes 4. The housings 12 and the air suction chamber 10 are connected through connecting holes 13. A one-way valve 14 is installed inside the connecting hole 13. An air pump 5 is installed on the outer surface of the base 1. Positioning holes 7 are provided at the four corners of the upper end face of the base 1. Positioning posts 6 are installed at the four corners of the lower end face of the cover plate 2. A through groove 3 is provided on the upper end face of the cover plate 2.

[0021] The positioning pin 6 corresponds one-to-one with the positioning hole 7, and the positioning pin 6 can be inserted into the inside of the positioning hole 7. A first magnet is installed on the lower end face of the positioning pin 6, and a second magnet is installed on the upper end face of the positioning hole 7. The magnetic poles of the first magnet and the second magnet are opposite, which can improve the position.

[0022] There are three cover plates 2 that are matched with the base 1, and the through grooves 3 opened on the surface of the three cover plates 2 are all different in size, which can ensure the stability of the connection between the cover plates 2 and the base 1 for transducer arrays of different sizes.

[0023] The air pump 5 is connected to the suction chamber 10 through a duct. Rubber pads are fixedly connected to the opposite side of the outer surface of each pair of clamps 801 by adhesive. When the air pump 5 is working, it generates negative pressure in the suction chamber 10, the connecting hole 13 and the through hole 4, which can generate uniform suction force on each position of the flexible backing placed inside the square groove 9.

[0024] The threads of each pair of threaded rods 805 are in opposite directions. A motor is installed in front of the strip groove 803 through the motor cavity. The output end of the motor is fixedly connected to the front end face of one of the threaded rods 805 through a coupling. The rear end face of the other threaded rod 805 is rotatably connected to the inner wall of the strip groove 803 through a bearing. When the motor works, it can drive the threaded rod 805 to rotate. The two threaded plates 806 can move simultaneously in a direction away from or towards each other, driving the clamping plate 801 to move.

[0025] Working principle: During use, a clamping mechanism is provided. The position of the strip plate is adjusted by controlling the switch of the electric push rod according to the size of the flexible backing. Then, the position of the clamping plate is adjusted by controlling the switch of the motor, placing the flexible backing inside the groove formed by the clamping plate and the strip plate. By opening the one-way valve covered by the flexible backing and turning on the air pump, negative pressure is generated in the suction chamber, corresponding connecting holes, and through holes. This creates uniform suction at various positions of the flexible backing placed inside the square groove. The cover plate, with three sets of through slots of different sizes, allows for the positioning and bonding of transducer arrays of different sizes. This invention can fix flexible backings of different sizes without easily causing wrinkles and can position transducer arrays of different sizes, improving its applicability.
