[0035] Reference Figures 1 to 4 In one embodiment of the present invention, a material strip detection device 100 is proposed, including several detection mechanisms 110 and an adjustment mechanism 150. The detection mechanism 110 includes a probe 111 and a detection system (not shown in the figure). The probe 111 is electrically connected to the detection system. When the probe 111 contacts the electronic component 11 on the material strip 10, it can conduct electricity between the electronic component 11 and the detection system, so that the electronic component 11 is electrically connected to the detection system. The detection system is used to detect the set parameters of the electronic component 11. The adjusting mechanism 150 is connected to the detecting mechanism 110. The adjusting mechanism 150 is connected to the detecting mechanism 110. The adjusting mechanism 150 includes a mounting seat 180, a material tape placement member 151 and a lifting mechanism 152. The detecting mechanism 110 is located above the material tape placement member 151. There is a material tape channel 170 between the detecting mechanism 110 and the material tape placement member 151. The lifting mechanism 152 is connected to the material tape placement member 151. The material tape placement member 151 is used to place the material tape 10 passing through the material tape channel 170. The lifting mechanism 152 is used to drive the electronic components 11 on the material tape placement member 151 to contact the probe 111.

[0036] Among them, the detection system is a circuit system for detecting the electrical parameters (such as resistance, capacitance and inductance, etc.) of the electronic component 11. The detection system can be a PCB (printed circuit board), an electric meter or other circuit detection equipment used to detect the electronic component 11 in the relevant field. The setting parameters of the electronic component 11 are the detection parameters that need to be set for different electronic components. For example, when the electronic component 11 is a resistor, the setting parameter is the resistance value; when the electronic component 11 is an inductor, the setting parameter is the inductance value. The probe 111 is a needle-shaped structure made of metal or other conductive materials and has conductivity. The lifting mechanism 152 is a mechanical structure that can be lifted and lowered in the up and down directions. The lifting mechanism 152 can be a mechanical structure such as a slider mechanism, a telescopic mechanism, a rack mechanism or a screw mechanism arranged up and down. After the lifting mechanism 152 is connected to the driving part, it can be lifted and lowered under the drive of the driving part, so that the material strip placement part 151 connected to the lifting mechanism 152 can also complete the corresponding lifting and lowering. The number of the detection mechanism 110 can be one or more, refer to Figure 1The material strip detection device 100 is provided with two detection mechanisms 110. The sizes of the probes 111 and the detection systems in the two detection mechanisms 110 can be set to be different, so that the two detection mechanisms 110 can respectively detect electronic components 11 of different sizes or different electrical parameters on different material strips 10.

[0037] The strip detection device 100 of the embodiment of the present invention can be used in a splicer. The strip detection device 100 of the embodiment of the present invention is installed at the inlet end of the splicer to detect the parameters of the electronic components 11 on the strip 10. This can determine whether the strip 10 of the splicer is misplaced, thereby preventing incorrect splicing caused by misplaced strips 10. The splicer is a mechanical device used to connect two strips 10 together. Its structure and operating method are well-known technologies in the relevant field.

[0038] The process of inspecting the material strip 10 by the material strip inspection device 100 in the embodiment of the present invention is as follows: During the production process, the material strip 10 is conveyed to the material receiving machine by a conveyor mechanism in related equipment on the production line. When the material strip 10 reaches the material strip channel 170, it continues to be conveyed until the material strip 10 is located in the material strip channel 170 and positioned within the position where the probe 111 can detect it. The material strip 10 stops conveying and is placed on the material strip placement member 151. The lifting mechanism 152 drives the material strip placement member 151 upward until the probe 111 contacts the electronic component 11 on the material strip 10. After the probe 111 contacts the electronic component 11, the electronic component 11 is electrically connected to the inspection system, and the inspection system detects the corresponding electrical parameters of the electronic component 11. After the inspection is completed, the lifting mechanism 152 descends to its original position. After confirming that there is no misplacement, the material strip 10 resumes production. The lifting mechanism 152, the conveyor mechanism, and other related mechanical structures can be controlled by a PLC (programmable logic controller). The structure and working principle of PLC (Programmable Logic Controller) are well-known technologies in the relevant field.

[0039] In the material strip detection device 100 in the embodiment of the present invention, the lifting mechanism 152 can drive the material strip placement piece 151 to rise or fall, so that the electronic components 11 of the material strip 10 on the material strip placement piece 151 can contact and separate with the probe 111, and the probe 111 can connect the electronic components 11 in contact with the probe 111 with the detection system, so that the detection of the electronic components 11 on the material strip 10 can be completed mechanized without manual operation, thereby improving production efficiency.

[0040] Reference Figure 2 and Figure 4In some embodiments of the present invention, the detection mechanism 110 further includes a probe fixing mechanism 120 and a pressing mechanism 130. The pressing mechanism 130 is connected to the probe fixing mechanism 120. A probe protection hole 121 is provided on the pressing mechanism 130. The probe protection hole 121 is located above the material strip channel 170. One end of the probe 111 is connected to the probe fixing mechanism 120, and the other end of the probe 111 is located in the probe protection hole 121. The pressing mechanism 130 can move in the up and down directions. The end of the probe 111 for detection is located in the probe protection hole 121, which can prevent the probe 111 from being damaged by collision, scratching, etc. The pressing mechanism 130 can move in the up and down directions, so that the probe 111 can be exposed from the probe protection hole 121 and contact the electronic components 11 on the material strip 10. The pressing mechanism 130 can be various types of slider mechanisms, telescopic mechanisms or other mechanical structures that can achieve up and down movement. Reference Figure 1 The probe fixing mechanism 120 and the pressing mechanism 130 may be connected via a support column 160 or other fixing structures.

[0041] Reference Figure 2 and Figure 4 In some embodiments of the present invention, the probe fixing mechanism 120 is provided with a plurality of probe mounting holes 112, and the pressing mechanism 130 is provided with probe protection holes 121 at positions corresponding to the probe mounting holes 112. The probe 111 is detachably connected to the probe fixing mechanism 120 and is inserted into the probe mounting hole 112 and the probe protection hole 121. The detachable connection between the probe 111 and the probe fixing mechanism 120 may be a threaded connection, a snap-on connection, or the like. By providing probe mounting holes 112 in multiple positions, the installation position of the probe 111 can be adjusted, thereby accommodating the detection of more different types of strips 10.

[0042] Reference Figure 3 and Figure 5In some embodiments of the present invention, the pressing mechanism 130 includes a plurality of pressing rods 131 and a pressing mounting plate 132. The pressing rods 131 include an inner tube 133 and an outer sleeve 134. The outer sleeve 134 is sleeved onto the inner tube 133 and is movable along the axial direction of the inner tube 133, which is the vertical direction. The outer sleeve 134 is connected to the pressing mounting plate 132, which is in turn connected to the outer sleeve 134. The pressing mounting plate 132 is provided with a probe protection hole 121. The outer sleeve 134 is slidably connected to the inner tube 133, and a gap may be provided between the outer sleeve 134 and the inner tube 133, thereby enabling the outer sleeve 134 to move along the axial direction of the inner tube 133. As the strip placement member 151 ascends, it first contacts the pressing plate 132, which then drives the outer sleeve 134, connected to the pressing plate 132, upward along the axial direction of the inner tube 133, thereby allowing the probe 111 to emerge from the probe protection hole 121 and contact the strip 10. The pressing rod 131 allows the pressing mechanism 130 to ascend, supported by the strip placement member 151. This eliminates the need for a drive element or transmission structure, saving costs and reducing the size of the strip inspection device 100.

[0043] Reference Figure 5 In some embodiments of the present invention, the pressing rod 131 further includes an elastic member 135. The elastic member 135 is connected between the inner tube 133 and the outer tube 134 and is capable of supporting the outer tube 134 when the outer tube 134 moves upward relative to the inner tube 133. Specifically, the elastic member 135 may be a spring. The elastic member 135 is sleeved outside the inner tube 133 and connects the outer tube 134 and the inner tube 133. A retaining ring is provided between the outer tube 134 and the inner tube 133 to prevent the inner tube 133 from falling out. When the outer tube 134 of the pressing rod 131 rises upward relative to the inner tube 133, the elastic member 135 supports the outer tube 134, generating resistance that hinders the further rise of the outer tube 134. This acts as a buffer and facilitates precise control of the rising height of the outer tube 134 of the pressing rod 131.

[0044] Reference Figure 4 and Figure 6 In some embodiments of the present invention, the pressing mechanism 130 further includes a height limiting mechanism 140, which is connected to the pressing mounting plate 132 and is used to prevent the pressing mounting plate 132 from moving along the axial direction of the inner tube 133. The height limiting mechanism 140 can be a baffle or block disposed above the pressing mounting plate 132, or an elastic mechanism capable of generating an elastic force in a direction opposite to the upward movement of the pressing mounting plate 132, thereby limiting the height of the pressing mounting plate 132 and preventing it from rising too high.

[0045] Reference Figure 6In some embodiments of the present invention, the height limiting mechanism 140 includes a height limiting plate 141 and a plurality of height limiting connectors 142. The height limiting connectors 142 are connected to the height limiting plate 141 and between the height limiting plate 141 and the press-fit mounting plate 132. The press-fit mounting plate 132 is movable along the length of the height limiting connectors 142. The adjustment mechanism 150 also includes a mounting seat 180. The mounting seat 180 is connected to the frame. The height limiting plate 141 is connected to the mounting seat 180. The height limiting plate 141 is configured to limit the movement of the press-fit mounting plate 132 along the length of the height limiting connectors 142. During the rising process, the press-fit mounting plate 132 moves along the length of the height limiting connectors 142 and is ultimately abutted by the height limiting plate 141, thereby limiting the press-fit mounting plate 132 from further moving along the length of the height limiting connectors 142. The length of the height-limiting connector 142 is defined as the vertical direction. The height-limiting plate 141 is connected to the mounting base 180, and the height-limiting plate 141 is also fixed to the frame. The press-fit mounting plate 132 rises along the length of the height-limiting connector 142, and the height-limiting connector 142 is connected between the height-limiting plate 141 and the press-fit mounting plate 132, thereby preventing the press-fit mounting plate 132 from deviating during the rising process.

[0046] Reference Figure 6 In some embodiments of the present invention, the height limiting connector 142 includes a limiting portion 143, a connecting portion 144 and a sliding portion 145. A limiting hole 146 and a through hole 147 are provided on the press-fit mounting plate 132. The limiting hole 146 is connected to the through hole 147. A connecting hole 148 is provided on the height limiting plate 141. The connecting portion 144 is passed through the connecting hole 148 and is detachably connected to the height limiting plate 141. The sliding portion 145 is passed through the through hole 147. The limiting portion 143 is located in the limiting hole 146, and the width of the limiting portion 143 is greater than the width of the through hole 147. After the press-fit mounting plate 132 is connected to the height-limiting plate 141 via the height-limiting connector 142, the lower side of the press-fit mounting plate 132 is held against the limiting portion 143. The sliding portion 145 of the height-limiting connector 142 determines the height at which the press-fit mounting plate 132 can be raised. When the press-fit mounting plate 132 reaches its highest point along the sliding portion 145, it is held against the limiting plate. The removable connection between the connecting portion 144 and the height-limiting plate 141 can be achieved through threaded or snap-fit ​​connections. By replacing the height-limiting connector 142 with sliding portions 145 of different lengths, the maximum height at which the press-fit mounting plate 132 can be raised can be adjusted.

[0047] Reference Figure 1 and Figure 3 In some embodiments of the present invention, the detection mechanism 110 further includes a plurality of product positioning posts, which are connected to the press-fit mounting plate 132 and extend in a direction close to the material strip placement member 151. Figure 1In the related art, a positioning hole 12 is provided on the material strip 10 , and the positioning post is inserted into the positioning hole 12 as the press-fit mounting plate 132 descends, thereby ensuring the accuracy of positioning and allowing the probe 111 to accurately contact the electronic component 11 .

[0048] Reference Figure 1 In some embodiments of the present invention, the strip inspection device 100 further includes a transverse movement mechanism 153, to which the adjustment mechanism 150 is connected. The transverse movement mechanism 153 is configured to drive the adjustment mechanism 150 to move horizontally. Through the transverse movement mechanism 153, during production processes where strip 10 inspection is not required, the adjustment mechanism 150 and the inspection mechanism 110 connected thereto can be moved horizontally to one side of the feeder or other production equipment's inlet or outlet to avoid interference. The transverse movement mechanism 153 can be a slider mechanism or a lead screw mechanism.

[0049] In some embodiments of the present invention, the lifting mechanism 152 includes two slide rails and a sliding seat. The two slide rails are respectively slidably connected to the sliding seat, and the sliding seat is connected to the material placement member 151. The sliding seat can move up and down along the two slide rails. The provision of dual slide rails can make the sliding seat more stable when it is raised and lowered.

[0050] Reference Figure 1 In some embodiments of the present invention, the strip detection device 100 further includes a position sensor 182 located on one side of the strip placement member 151. The position sensor 182 can detect the height to which the pressing and mounting plate 132 rises relative to the detection mechanism 110. By setting a height threshold, the lifting mechanism 152 can prevent the pressing and mounting plate 132 from rising too high and thereby damaging the probe 111.

[0051] Reference Figure 1 In some embodiments of the present invention, the probe fixing mechanism 120 further includes a header connector 181, which is a structure commonly used in the related art for connecting PCB wiring. The header connector 181 brings together the circuit wiring of the detection system, facilitating circuit connection of the detection system.

[0052] Reference Figure 7 In an embodiment of the present invention, a material splicer is further provided, comprising the material strip detection device 100 and the material splicer 200 of the above embodiment. The material strip detection device 100 is used to detect the material strip 10 passing through the material splicer; the material splicer 200 includes a feed port and a discharge port, with the material strip detection device 100 being provided at the feed port, or both the feed port and the discharge port.

[0053] Among them, the material receiving device 200 is a mechanical device for connecting two material strips 10 into one, and its structure and working method are both well-known technologies in the relevant field. Through the material strip detection device 100, the electrical parameters of the electronic components 11 on the material strip 10 at the feed port end of the material receiving device 200 can be detected, so that it can be judged whether the operator has placed the material strip 10 by mistake. The material strip detection device 100 does not require manual operation and can automatically complete the detection under the drive of the driving member, thereby improving production efficiency. In addition, the feed port and the discharge port of the material receiving device 200 are respectively provided with a material receiving machine of the material strip detection device 100. By comparing the data detected by the front and rear material strip detection devices 100, it can be judged whether the front and rear material strips 10 are consistent, without the need for manual judgment, further improving production efficiency.
