As described in the background art, the conventional detection device generally includes a film-type sensing sheet and a collector matched with the film-type sensing sheet, and when multiple discrete objects need to be subjected to compression analysis at the same time, multiple sets of detection devices are generally required to be configured, which is inconvenient for a user to operate.

In order to solve the above-mentioned problems, according to an aspect of the present application, as shown in fig. 1-2, an embodiment of the present application provides a detection apparatus 1, the detection apparatus 1 including at least two thin film sensor sheets 100, a transmission assembly 200, and a collector 300. The transmission assembly 200 is provided with a collector docking port 210 and at least two docking ends 220, the collector docking port 210 is electrically connected with each docking end 220, the collector 300 is electrically connected to the collector docking port 210, and each thin film sensor chip 100 is electrically connected to each docking end 220 in a one-to-one correspondence.

In the embodiment of the application, each thin film type sensing sheet 100 in the detection device 1 is connected with the same transmission assembly 200, the signal collection of a plurality of thin film type sensing sheets 100 can be realized only by one collector 300, the plurality of collectors 300 are not required to be arranged, when a plurality of objects are required to be detected, only one transmission assembly 200 is required to be fixed, the position of the thin film type sensing sheets 100 is not required to be adjusted one by one, and the use is simpler and more convenient. In addition, it can be understood that, since the detection device 1 in the embodiment of the present application only needs to provide one collector 300 to collect signals of the plurality of film-type sensing sheets 100, there is no need to provide a plurality of collectors 300, so that the number of collectors 300 is reduced, and the cost of the detection device 1 is reduced.

It should be noted that, the type of the film type sensing sheet 100 in the present application may be a film type pressure sensing sheet, a film type temperature and pressure integrated sensing sheet, a film type humidity sensing sheet, etc., and may be specifically selected according to the actual detected physical quantity.

Taking the film type sensing sheet 100 as an example of the film type pressure sensing sheet, the detection principle of the detection device 1 will be described: the film type pressure sensing sheet is configured to change an electrical signal based on the magnitude of the applied pressure, and when the detecting device 1 is operated, an excitation signal is sent to the transmission assembly 200 through the collector 300, the excitation signal is transmitted to the film type pressure sensing sheet through the transmission assembly 200, and the collector 300 acquires the electrical signal fed back by the film type pressure sensing sheet. It will be appreciated that the pressure applied by the thin film pressure sensor chip can be obtained directly or indirectly by the collector 300 through the feedback electric signal. In this way, the collection of the signals of the plurality of film pressure sensing sheets can be realized by only one collector 300, so that the pressure detection of the plurality of objects 11 to be detected is realized.

In one embodiment, the thin film sensor chip 100 is a thin film pressure sensor chip. The film type pressure sensing sheet is a sensing sheet capable of detecting pressure distribution in a certain area, and the pressure distribution condition and the pressure size of a corresponding detected object can be obtained through the film type pressure sensing sheet. Specifically, the film type pressure sensing sheet mainly comprises an upper layer and a lower layer of flexible bendable film materials, wherein the upper layer is a pressure sensing functional film, the lower layer is an electrode film, when the film type pressure sensing sheet is pressed, the upper layer and the lower layer of films are contacted, the contact area of the film type pressure sensing sheet can be changed along with the change of pressure, and therefore the electrode terminal can generate the change of electrical impedance signal quantity along with the change of pressure.

Referring to fig. 2 to 4, in one embodiment, the transmission assembly 200 further includes an electrical connection device 230 and a substrate 240, the collector docking port 210 is disposed on the substrate 240, the docking port 220 is disposed on the electrical connection device 230, and the docking port 220 is respectively connected to the substrate 240 and the thin film sensor chip 100 to electrically connect the substrate 240 and the thin film sensor chip 100.

As an embodiment, the butt-joint end 220 includes a transmission wire, where each of the thin film sensor chip 100 and the substrate 240 has a plurality of pins, one end of the transmission wire is used for connecting the pins of the substrate 240, and the other end of the transmission wire is used for connecting the corresponding pins of the thin film sensor chip 100. In this way, electrical conduction between the thin film sensor chip 100 and the substrate 240 can be achieved through the docking terminal 220 disposed on the electrical connection device 230.

With continued reference to fig. 3 and 4, in one embodiment, the pins of the substrate 240 and the pins of the thin film sensor chip 100 each include an input pin for transmitting an input signal and an output pin for transmitting an output signal, and the transmission wires of the docking terminal 220 include an input wire 221 for transmitting the input signal and an output wire 222 for transmitting the output signal. The collector docking port 210 includes an input pin for transmitting an input signal and an output pin for transmitting an output signal. The input pins of the collector docking port 210 are electrically connected to the input pins of the thin film sensor chip 100 through the input pins of the substrate 240 and the input wires 221 of the docking end 220, and the output pins of the collector docking port 210 are electrically connected to the output pins of the thin film sensor chip 100 through the output pins of the substrate 240 and the output wires 222 of the docking end 220. Through the design, the detection information of each thin film sensor chip 100 can be obtained through the collector 300.

Referring to fig. 4 and 5, in one embodiment, the electrical connection device 230 is a flexible and bendable connector. Specifically, the electrical connection device 230 includes a flexible and bendable film 231, and the input wire 221 and the output wire 222 of the docking end 220 are formed or disposed on the film 231. In this way, the relative position between the thin film sensor sheet 100 and the substrate 240 can be accommodated directly by bending the electrical connection device 230.

It can be understood that when the detecting device 1 is used to detect an object to be detected, the portion of the thin film sensor strip 100 used for detection and the substrate 240 may be located on different surfaces or different spaces, and if the mounting manner of the detecting device 1 is adapted by bending the substrate 240 or the portion of the thin film sensor strip 100 used for detection, the thin film sensor strip 100 or the substrate 240 will be greatly affected, so in the present utility model, the electrical connection device 230 can adapt to different mounting positions by using a flexible bendable connector.

In some more specific embodiments, the pins of the thin film sensor chip 100, the transmission wires of the butt-joint end 220, and the pins of the substrate 240 are in a flat cable structure, and the substrate 240 may be a PCB (Printed Circuit Board ) or an FPC (Flexible Printed Circuit board, flexible printed circuit board) or an FFC (Flexible Flat Cable ) provided with a stiffener. In some specific embodiments, the electrical connection device 230 may be an FPC or an FFC.

It can be appreciated that, since the docking end 220 is disposed on the electrical connection device 230, the substrate 240 and the thin film sensor chip 100 are electrically connected through the electrical connection device 230, and thus, the electrical connection between the electrical connection device 230 and the substrate 240 can be achieved through a fixed or detachable connection manner, and the electrical connection between the electrical connection device 230 and the thin film sensor chip 100 can also be achieved through a fixed or detachable connection manner.

Referring to fig. 6, as an embodiment, the substrate 240 and the thin film sensor chip 100 are fixedly connected to the electrical connection device 230. By the design, the stability of electrical conduction between the substrate 240 and the thin film type sensing piece 100 can be ensured, and separation between the substrate 240 and the thin film type sensing piece 100 in the using process is avoided.

As one embodiment, the electrical connection device 230 is detachably connected to one of the substrate 240 and the thin film sensor chip 100, and the electrical connection device 230 is detachably connected or fixedly connected to the other. The following three connection structure modes are adopted in the embodiment:

referring to fig. 7, as an embodiment, the substrate 240 and the thin film sensor chip 100 are detachably connected to the electrical connection device 230. So designed, when the substrate 240, any of the thin film sensor sheets 100, or any of the electrical connection devices 230 is damaged, the damaged components can be directly replaced without replacing the entire detection device 1. Meanwhile, for different types of substrates 240, as long as the types of interfaces connected with the electrical connection device 230 are consistent, the thin film sensor chip 100 and the electrical connection device 230 can be used interchangeably between the different types of substrates 240, further improving the practicality of the detection device 1. Meanwhile, the substrate 240, the thin film sensor chip 100 and the electrical connection device 230 may be disassembled into separate units, which is more convenient for storage and transportation.

Referring to fig. 8, as another embodiment, the substrate 240 is fixedly connected to the electrical connection device 230, and the thin film sensor chip 100 is detachably connected to the electrical connection device 230. By fixing the electrical connection device 230 on the substrate 240 in advance, the number of parts is reduced, the use of the device is more convenient for a user, and the loss of the parts can be further reduced. Meanwhile, when any one of the thin film type sensing sheets 100 is damaged, the damaged thin film type sensing sheet 100 can be directly replaced without replacing the entire detecting device 1.

Referring to fig. 9, as an embodiment, the thin film sensor chip 100 is fixedly connected to the electrical connection device 230, and the substrate 240 is detachably connected to the electrical connection device 230. By fixing the electrical connection device 230 on the film sensor chip 100 in advance, the number of parts is reduced, the use of a user is facilitated, and the loss of the parts can be further reduced.

Referring to fig. 6, as a possible implementation, when the substrate 240 and the electrical connection device 230 are fixedly connected, the electrical connection device 230 may be fixed on the substrate 240 by bonding, and the transmission wires of the butt-joint ends 220 are disposed in one-to-one correspondence with the pins of the corresponding substrate 240 and are fixed and electrically connected by soldering or bonding. When the film-type sensing sheet 100 and the electrical connection device 230 are fixedly connected, the electrical connection device 230 can be fixed on the film-type sensing sheet 100 by bonding, and the pins on the film-type sensing sheet 100 are arranged in one-to-one correspondence with the transmission wires of the butt-joint end 220 and are fixed by welding or bonding, etc. to realize electrical conduction. Further, in order to improve the safety of the conducting position, the pins and the conductive terminals can be coated by means of glue injection for protection.

The electrical connection device 230 and the substrate 240, and/or the electrical connection device 230 and the thin film sensor chip 100 are detachably connected through the docking device 250. When the transmission wire of the butt joint end 220 on the electric connection device 230 and the pin of the substrate 240 are respectively butt-jointed with the two opposite ends of the conductive terminal, the movable pressing plate clamps the pin of the substrate 240 and the transmission wire of the butt joint end 220 between the movable pressing plate and the conductive terminal, so that the substrate 240 is electrically connected with the butt joint end 220 through the conductive terminal; when the transmission wire of the butt joint end 220 and the pin of the thin film type sensing piece 100 on the electrical connection device 230 are respectively butt jointed with the two opposite ends of the conductive terminal, the movable pressing plate clamps the pin of the thin film type sensing piece 100 and the transmission wire of the butt joint end 220 between the movable pressing plate and the conductive terminal, so that the thin film type sensing piece 100 is electrically connected with the butt joint end 220 through the conductive terminal.

More specifically, the pins of the thin film sensor chip 100, the transmission wires of the docking end 220, and the pins of the substrate 240 are in a flat cable structure, and the docking device 250 may be a flip-type FFC/FPC connector.

It will be appreciated that by adjusting the number and type of electrical connection means 230, different types of detection means 1 may be obtained to accommodate different types of objects to be detected.

Further, it is understood that the shapes of the respective thin film sensor sheets 100 may be the same or different. That is, the shapes of the detection areas of the thin film sensor sheets 100 may be the same or different, so long as the thin film sensor sheet 100 and the corresponding butt end 220 can be electrically connected. Preferably, the number and types of the transmission wires of each butt end 220 in the detection device 1 are the same, and each thin film sensor chip 100 is a sensor chip with the same structure, i.e. the types, the numbers and the positions of the pins of each thin film sensor chip 100 are the same.
