[0026] The present application will now be described in detail with reference to the accompanying drawings and optional embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0027] Figure 1 This is a schematic diagram of the first embodiment of the detection device of this application. Figure 2 This is a disassembly diagram of the clamping assembly in the first embodiment of the testing device of this application; as shown Figure 1 and Figure 2 As shown in the figure, this application discloses a detection device 100 for detecting a sample 200 to be tested. The device includes a base 110, a vertical rod 120, a clamping assembly 130, a transmission line 160, a probe holder 170, and a switch 180. The vertical rod 120 is mounted on the top of the base 110. The clamping assembly 130 is movably connected to the vertical rod 120 and can move along the extension direction of the vertical rod 120. The probe holder 170 is connected to the clamping assembly 130, and a plurality of probes 172 are provided on the side of the probe holder 170 near the base 110. The probes 172 are connected to the switch 180 via the transmission line 160. The probes 172 are used to detect the voltage signal of the sample 200 to be tested and transmit the detection signal to the switch 180 via the transmission line 160 to calculate the resistivity of the sample 200 to be tested.

[0028] This application improves upon the traditional detection device 100 by providing stable support for the entire device with a base 110, preventing shaking during operation and enhancing overall stability. The probe holder 170 is clamped and fixed by a clamping assembly 130, which provides stable clamping. When the clamping assembly 130 moves on the upright 120, it simultaneously moves the probe holder 170, allowing for height adjustment of the probe 172 to accommodate samples 200 of varying thicknesses, thus improving detection accuracy. Furthermore, the probe holder 170 is less prone to movement under the clamping of the clamping assembly 130. The movement during the movement ensures the stability of the probe holder 170 during adjustment. Specifically, through the coordinated operation of the base 110, the upright 120, the clamping assembly 130, the transmission line 160, the probe holder 170, and the switch 180, the probe holder 170 can be stably fixed and its position adjusted. The voltage signal of the sample 200 to be tested is accurately detected by the probe 172. Subsequently, the detected signal is transmitted to the switch 180 via the transmission line 160 to calculate the resistivity of the sample 200 to be tested. The quality of the sample is judged based on the resistivity, thereby improving the accuracy and stability of the detection of the sample 200.

[0029] It should be noted that the test sample 200 in this application can be copper foil or other test samples 200 with similar properties to copper foil. This application only uses copper foil as an example to illustrate the test sample 200.

[0030] The specific working principle of the detection device 100 of this application is as follows: First, the copper foil sample to be tested is placed on the base 110, and the position of the copper foil is adjusted so that it is located at a suitable position below the probe holder 170 and corresponds to the position of the probe 172 on the probe holder 170; then, according to the thickness of the copper foil sample, the position of the clamping assembly 130 on the upright 120 is adjusted so that the probe holder 170 is adjusted in height as the clamping assembly 130 moves, until the probe 172 on the probe holder 170 is close to but not in contact with the surface of the copper foil, reaching a suitable detection height, and the detection process is started through an external device. In the sequence, when there are four probes on the probe holder, a set current is applied to the two outer probes 172 on the probe holder 170. At this time, the two inner probes 172 will generate corresponding voltage signals. These voltage signals are transmitted to the external device through the probe holder 170 and the switch 180. The external device calculates the resistivity of the copper foil according to Ohm's law based on the received voltage signal and the known current value, and compares it with the preset quality standard to determine whether the conductivity of the copper foil meets the requirements. If the resistivity of the copper foil does not meet the standard, there is a problem with the copper foil process, which can be corrected.

[0031] Specifically, a signal transmission head 173 is provided on the top of the probe holder 170, and the switch 180 includes a first port 181 and multiple second ports 182. One end of the transmission line 160 is connected to the first port 181, and the other end is connected to the signal transmission head 173. Each second port 182 is connected to a data line 184, and the end of the data line 184 away from the second port 182 is connected to a data pin 185. The data pin 185 is used to transmit the detection signal to an external device for data processing.

[0032] In this application, a transmission line 160 is connected between the first port 181 of the switch 180 and the signal transmission head 173 on the top of the probe holder 170, while multiple second ports 182 of the switch 180 are connected to data pins 185 via data lines 184, thereby connecting to external devices using the data pins 185 to form a complete signal transmission path.

[0033] Each data line 184 transmits data signals to each probe 172. For example, when there are four probes 172, four data lines 184 are needed to connect to the switch 180. The switch 180 switches the corresponding probe 172 to output signals. The signals detected by different probes 172 are transmitted to external devices via data lines 184 for comparison, thereby calculating accurate detection results and improving detection accuracy.

[0034] The number of probes 172 and data lines 184 can be determined according to the actual detection situation, as long as it is ensured that the signal of each probe 172 can be transmitted to the corresponding data line 184. This application does not impose a limit; this application only illustrates the example with 4 probes 172 and 4 corresponding data lines 184:

[0035] A sealing plate 183 is installed on one side of the switch 180. The four corners of the sealing plate 183 are threadedly connected to the switch 180 with bolts. The outer surface of the sealing plate 183 has four connecting slots, which can be used to connect multiple second ports 182. Data cables 184 are fixedly connected to the second ports 182 of the switch 180. Data pins 185 are fixedly installed at the bottom of the data cables 184 to realize the transmission of detection data. Four equally spaced probes 172 are arranged on the bottom of the probe holder 170 for detecting voltage signals on the surface of the copper foil. When current is applied to the two outer probes 172, a voltage is generated between the two inner probes 172. This voltage signal is transmitted to the external device through the signal transmission head 172 of the probe holder 170, the transmission line 160, and the data line 184 and data pin 185 connected to the second port. The external device calculates the resistivity of the copper foil according to Ohm's law based on the received voltage signal and the known current value, and compares it with the preset quality standard to determine whether the conductivity of the copper foil meets the requirements. If the resistivity of the copper foil does not meet the standard, there is a problem with the copper foil process, which can be corrected.

[0036] Furthermore, the clamping assembly 130 includes a fixing member 131, a fixing rod 140, and an adjusting frame 150. The adjusting frame 150 is movably connected to the upright rod 120 and can move along the extension direction of the upright rod 120. One end of the fixing rod 140 is connected to the fixing member 131, and the other end is connected to the adjusting frame 150. The fixing member 131 is clamped on the outer surface of the probe holder 170.

[0037] In this embodiment, the probe holder 170 is clamped by the fixing member 131, so that the probe holder 170 is fixed on the fixing member 131 and connected to the adjustment frame 150 through the fixing rod 140. When the adjustment frame 150 moves along the extension direction of the upright 120, the adjusting member drives the fixing member 131 and the probe holder 170 connected to the fixing member 131 to move, thereby adjusting the height of the probe holder 170 so that the probe 172 on the probe holder 170 maintains a suitable test distance between it and the sample 200 to be tested. During the movement, the probe holder 170 is fixed by the fixing member 131, so that it does not shake, which helps to improve the stability of the detection.

[0038] Specifically, a slide cylinder 151 is provided on the side of the adjusting frame 150 away from the clamping assembly 130, and a toothed groove 121 is provided on the outer surface of the upright 120, with the toothed groove 121 arranged along the extension direction of the upright 120; the adjusting frame 150 is sleeved on the upright 120 through the slide cylinder 151 and engaged with the toothed groove 121; a gear rod 153 is also provided on the adjusting frame 150, which is used to adjust the movement of the slide cylinder 151 along the extension direction of the upright 120.

[0039] The sliding cylinder 151 on the adjusting frame 150 is sleeved on the upright 120, so that the adjusting component is connected to the upright 120 and can move along the extension direction of the upright 120 by sliding. The design of the sliding cylinder 151 makes it easier for the adjusting frame 150 to move on the upright 120 without being obstructed.

[0040] The toothed groove 121 on the outer surface of the upright 120 is connected to the gear rod 153 of the adjusting frame 150. When the height of the adjusting frame 150 needs to be adjusted, the gear rod 153 is rotated to drive the adjusting frame 150 to move up and down relative to the upright 120, thereby controlling the height of the adjusting frame 150 and thus controlling the height of the probe holder 170 connected to the adjusting frame 150. This ensures that the probe 172 on the probe holder 170 can maintain a suitable testing distance with the sample to be tested, which is beneficial to improving testing efficiency.

[0041] Furthermore, an opening 152 is provided on the side wall of the slide cylinder 151, and a gear 154 is provided on the gear rod 153 at the position corresponding to the opening 152. The gear 154 is engaged with the tooth groove 121 through the opening 152. Since the slide cylinder 151 is sleeved on the upright rod 120, the opening 152 on the side wall of the slide cylinder 151 exposes the tooth groove 121 on the upright rod 120. In this way, the gear 154 on the gear rod 153 can contact and engage with the tooth groove 121 on the upright rod 120. By rotating the gear rod 153, the gear 154 on the gear rod 153 moves on the tooth groove 121 of the upright rod 120. This allows the adjusting frame 150 to rise or fall relative to the upright rod 120 through the gear rod 153. The adjusting frame 150 drives the clamping assembly 130 and the probe frame 170 to move up and down along the upright rod 120 until the probe 172 is close to but not in contact with the copper foil surface, reaching a suitable detection height. This ensures that the probe 172 and the copper foil surface can maintain the best contact state, improving detection accuracy.

[0042] Figure 3 This is a disassembly diagram of the clamping component in the second embodiment of the testing device of this application. Figure 3 The illustrated embodiment is based on Figure 1 Improvements, such as Figure 3 As shown, the fixing member 131 is provided with a through hole 132, and the clamping assembly 130 also includes a limiting rod 155. The limiting rod 155 abuts against the probe holder 170 through the through hole 132 to limit the probe holder 170.

[0043] In this embodiment, the limiting rod 155 can be connected to the through hole 132 on the fixing member 131 by screwing. By screwing, the limiting rod 155 can move along the through hole 132, thereby fastening and loosening the probe holder 170 on the fixing member 131, so that the position of the probe holder 170 relative to the clamping assembly 130 can be adjusted.

[0044] In the actual testing process, if there is still an error in the test distance after the position of the clamping assembly 130 relative to the upright 120 is adjusted, the limiting rod 155 can be loosened by screwing it to loosen the probe holder 170 and the fixing member 131, thereby adjusting the position between the probe holder 170 and the fixing member 131. This results in a fine adjustment of the distance between the probe holder 170 and the sample 200 to be tested, so that the probe 172 on the probe holder 170 and the sample 200 to be tested are in a suitable test position. Then, the limiting rod 155 is tightened by screwing it to limit and fix the probe holder 170 and the fixing member 131, so as to facilitate stable testing of the sample 200 and improve the accuracy and stability of the test.

[0045] Since the transmission line 160 needs to connect from the switch 180 to the probe holder 170, the transmission path is relatively long. During the frequent position adjustments of the probe holder 170 on the pole 120, if the transmission line 160 is completely exposed to the external environment without restraint, it is prone to tangling and knotting. Based on this problem, this application also improves the detection device 100, as follows:

[0046] Figure 4 This is a schematic diagram of the third embodiment of the detection device of this application, as shown below. Figure 4 As shown, the base 110 has a first connecting hole 111 and a second connecting hole 112. The first connecting hole 111 is located on the top surface of the base 110, and the second connecting hole 112 is located on the side surface of the base 110. The upright 120 is connected to the base 110 through the first connecting hole 111. A cavity 124 is provided inside the upright 120, and a first opening 122 and a second opening 123 are provided on the upright 120. The first opening 122 is located at the top of the upright 120, and the second opening 123 is located at the bottom of the upright 120, corresponding to the position of the second connecting hole 112. A portion of the transmission line 160 is located inside the cavity 124 of the upright 120. One end of the transmission line 160 is connected to the signal transmission head 173 through the first opening 122, and the other end is connected to the first port 181 of the switch 180 through the second opening 123 and the second connecting hole 112.

[0047] The difference between this embodiment and the previous embodiment is that in this embodiment, the upright 120 has a hollow structure, and a first opening 122 is provided at the top of the upright 120. A first connecting hole 111 for connecting the upright 120 is provided on the base 110. When the upright 120 is inserted into the first connecting hole 111 and connected to the base 110, the second opening 123 at its bottom corresponds exactly to the position of the second connecting hole 112 on the base 110. This allows one end of the transmission line 160 to be connected to the switch 180, and the other end to pass sequentially through the base 110. The second connecting hole 112 on the base 110 and the second opening 123 on the upright 120 enter the interior of the upright 120 and extend out from the first opening 122 at the top of the upright 120 to connect to the signal transmission column on the probe holder 170. This makes part of the transmission line 160 located inside the base 110 and part inside the upright 120, constrained by the upright 120. In this way, when the probe holder 170 is adjusted on the upright 120, the transmission line 160 is less likely to get tangled or twisted, ensuring the normal operation of the detection device 100 and improving detection efficiency.

[0048] Figure 5 This is a schematic diagram of the fourth embodiment of the detection device of this application, as shown below. Figure 5 As shown, a probe plate 171 is provided on the side of the probe holder 170 near the base 110, and multiple probes 172 are mounted on the probe plate 171; a receiving groove 113 is provided on the base 110 at the position corresponding to the probe plate 171, and the receiving groove 113 is used to place the sample 200 to be tested.

[0049] The difference between this embodiment and the previous embodiment is that, in this embodiment, a receiving groove 113 is also provided at the position of the base 110 corresponding to the probe plate 171. In the actual testing process, the sample to be tested 200 can be placed into the receiving groove 113 first. Since the position of the receiving groove 113 corresponds to the position of the probe plate 171, when the sample to be tested 200 is placed into the receiving groove 113, it corresponds exactly to the position of the probe 172 on the probe plate 171. In this way, the tester does not need to frequently adjust the position of the sample to be tested 200, which is convenient for the tester to operate and position, and helps to improve the testing efficiency.

[0050] Figure 6 This is a schematic diagram of the fifth embodiment of the detection device of this application, as shown below. Figure 6 As shown, a suction cup 114 is provided at the bottom of the base 110, and the suction cup 114 is used to connect with the contact surface.

[0051] The difference between this embodiment and the previous embodiment is that in this embodiment, a suction cup 114 is also installed at the bottom of the base 110. When the base 110 is installed on a contact surface such as a desktop or machine table, the suction cup 114 will first contact the contact surface. Due to the influence of the weight of the base 110 and the components supported by the base 110, the suction cup 114 will be pressed down, thereby compressing the suction cup 114 and expelling the air that was originally inside the suction cup 114, thus forming a negative pressure adsorbed on the contact surface. In this way, the entire detection device 100 is not easy to shake, further improving the stability of the detection device 100.

[0052] Of course, in order to ensure that the entire detection device 100 can be stably installed on the contact surface, suction cups 114 can be installed at the four corners of the bottom of the base 110. The suction cups 114 at the four corners fix the detection device 100 so that it is not easy to separate from the contact surface, and it is also beneficial to ensure that the entire detection device 100 is on a horizontal plane, thus ensuring the accuracy of the detection. The specific number of suction cups 114 can be set according to actual needs. In this embodiment, only four suction cups 114 located at the bottom of the base 110 are used as an example, and are not intended to limit the number of suction cups 114.

[0053] Figure 7 This is a schematic diagram of one embodiment of the detection system of this application, as shown below. Figure 7 As shown in the illustration, this application also discloses a detection system 10, including a data processing device 300. The detection system 10 further includes the aforementioned detection device 100, which is connected to the data processing device 300. The data processing device 300 processes the signals detected by the detection device 100. Based on the received voltage signal and the known current value, the data processing device 300 calculates the resistivity of the copper foil according to Ohm's law and compares it with a preset quality standard to determine whether the conductivity of the copper foil meets the requirements. If the resistivity of the copper foil does not meet the standard, there is a problem with the copper foil process, which can be corrected.

[0054] In traditional testing systems, the testing device needs to be frequently adjusted when testing samples of different thicknesses. This causes the testing device to shake, which affects the accuracy and stability of the test.

[0055] Based on the aforementioned problems, this application improves the detection device 100 in the traditional detection system 10 by setting a base 110 to provide stable support for the entire device, preventing shaking during operation and improving the overall stability of the device. The probe holder 170 is clamped and fixed by a clamping assembly 130, which provides stable clamping and fixation. When the clamping assembly 130 moves on the upright 120, it simultaneously moves the probe holder 170, thereby adjusting the height of the probe 172 to accommodate test samples 200 of different thicknesses and improve detection accuracy. Furthermore, the probe holder 170 is less prone to movement under the clamping of the clamping assembly 130. The shaking that occurs during the movement ensures the stability of the probe holder 170 during adjustment. That is, through the coordinated work of the base 110, the upright 120, the clamping assembly 130, the transmission line 160, the probe holder 170, and the switch 180, the probe holder 170 can be stably fixed and its position adjusted. The voltage signal of the sample 200 to be tested is accurately detected by the probe 172. Subsequently, the detected signal is transmitted to the switch 180 via the transmission line 160 to calculate the resistivity of the sample 200 to be tested. The quality of the sample to be tested is judged based on the resistivity, thereby improving the accuracy and stability of the detection of the sample 200 to be tested, and thus improving the overall stability and accuracy of the detection system 10.

[0056] It should be noted that the inventive concept of this application can form many embodiments, but due to the limited space of the application documents, they cannot all be listed. Therefore, without conflict, the embodiments described above or the technical features can be arbitrarily combined to form new embodiments.
