The lower end of the tensioning cylinder 104 is provided with a tensioning claw 1041 that is inserted into the through hole 302 of the tray rack and opens to tighten. The input ends of each output channel are located below the sorting mechanism 1, and the tray rack 3 that has been inspected is sent into the corresponding output channel through the sorting mechanism 1.

[0029] like Figures 1-2 and Figure 4As shown, in this embodiment, the sorting mechanism 1 includes a horizontal mounting base 101, a horizontal moving base 102, and a lifting base 103. The horizontal mounting base 101 is provided with a horizontal driving mechanism. The horizontal moving base 102 is slidably connected to the horizontal mounting base 101 and driven to move by the horizontal driving mechanism. The horizontal moving base 102 is provided with a lifting mechanism. The lifting base 103 is slidably connected to the horizontal moving base 102 and driven to rise and fall by the lifting mechanism. The tensioning cylinder 104 is provided on the lifting base 103.

[0030] like Figures 1-2 and Figure 4 As shown, in this embodiment, the lateral drive mechanism includes a lateral drive belt 1011, a drive pulley 1014, a driven pulley 1012, and a lateral motor 1015. The drive pulley 1014 and the driven pulley 1012 are respectively fixed at both ends of the lateral mounting base 101. One end of the lateral drive belt 1011 is wrapped around the drive pulley 1014, and the other end is wrapped around the driven pulley 1012. The drive pulley 1014 is driven to rotate by the lateral motor 1015, thereby driving the lateral drive belt 1011 to move. The lateral moving base 102 has a connecting seat on its rear side that is fixedly connected to the lateral drive belt 1011.

[0031] like Figures 1-2 and Figure 4 As shown, in this embodiment, the transverse mounting base 101 is provided with a groove, and the transverse drive belt 1011, the driving pulley 1014 and the driven pulley 1012 are all provided in the groove. The ends of the groove walls on both sides are provided with transverse slide rails 1013, and the transverse moving base 102 is provided with a transverse slider that cooperates with the transverse slide rail 1013 on the corresponding side.

[0032] like Figures 1-2 and Figure 4 As shown, in this embodiment, the lifting mechanism includes a lifting motor 1021, a lead screw, and a lead screw nut. The lifting motor 1021 and the lead screw are both mounted on the transverse moving seat 102. The lead screw is driven to rotate by the lifting motor 1021. The lead screw nut is fitted onto the lead screw. The lifting seat 103 is fixedly connected to the lead screw nut.

[0033] like Figure 2 As shown, in this embodiment, the lifting seat 103 includes a lifting slide plate 1031 and a mounting side plate 1032. The lifting slide plate 1031 is slidably connected to the transverse moving seat 102. The transverse moving seat 102 is provided with a lifting slide rail along the vertical direction.

The mounting side plate 1032 is vertically fixed on the lifting slide plate 1031. The tensioning cylinder 104 is provided on the mounting side plate 1032.

[0034] like Figure 2 As shown, in this embodiment, the tensioning cylinder 104 is provided with a marking mounting plate 1042, and the marking mounting plate 1042 is provided with a marking device 1043 for marking the qualified basin frame 3. The marking device 1043 is a technology known in the art and is a commercially available product.

[0035] like Figures 3-7 As shown, in this embodiment, the continuity detection mechanism 2 includes an outer support 201, a clamping cylinder 202, an inner support 207, and a lower lifting cylinder 204. The outer support 201 is located outside the transmission device 7, the clamping cylinder 202 is located on the outer support 201 and above the transmission device 7, and a clamping plate 203 is provided at the lower end of the clamping cylinder 202. The inner support 207 is located below the transmission device 7, and the lower lifting cylinder 204 is located on the inner support 207. A detection plate 205 is provided at the upper end of the lower lifting cylinder 204. When this utility model is in operation, the clamping plate 203 is used to clamp and fix the basin frame 3, and then the detection end seat 206 is driven by the detection plate 205 to insert into the basin frame terminal seat 301 for continuity detection.

[0036] like Figures 6-7 As shown, in this embodiment, the detection end seat 206 is provided with a detection hole 2063, and a detection probe 2061 is provided in the detection hole 2063. A conductive sheet 2062 is provided at the upper end of the detection end seat 206. The inner diameter of the detection hole 2063 must simultaneously meet the terminal position detection error requirements. During detection, the detection end seat 206 is driven to rise by a lower lifting cylinder 204. Figure 6 As shown, if the position of the basin holder terminal 303 is correct, the end of the basin holder terminal 303 will smoothly insert into the detection hole 2063 and contact the detection probe 2061 inside the detection hole 2063 to achieve continuity detection. Figure 5 As shown, if the position of the basin holder terminal 303 is incorrect, the end of the terminal cannot be inserted into the detection hole 2063. In this case, the end of the terminal will contact the conductive plate 2062 on the upper end of the detection end seat 206, thus generating a signal. The device control system determines that the terminal position is incorrect and controls the lower lifting cylinder 204 to stop moving. When the basin holder terminal 303 is successfully inserted into the detection hole 2063, there is a sufficient error gap between the basin holder terminal 303 and the inner wall of the detection hole 2063 to avoid triggering the conductive plate 2062 and causing false detection. The detection probe 2061 is connected to the lower continuity detection module through a wire. The above structure is a known technology in the field; for example, the continuity detection structure in patent CN215728729U can be used.

[0037] Furthermore, this invention can be configured with different numbers of output channels according to the detection conditions, such as... Figure 1As shown, in one embodiment of this utility model, there are two channels: a first output channel 6 and a second output channel 4. In this embodiment, only qualified and unqualified basin racks 3 can be distinguished, and the two types of basin racks 3 are picked up by the sorting mechanism 1 and placed at the input end of the corresponding output channel.

[0038] In another embodiment of this invention, three output channels can be provided, with the qualified basin holder 3 fed into the first output channel alone. Figure 7 The basin frame 3 with an incorrectly positioned terminal 303 is fed separately into the second output channel, while the basin frame terminal 303, although it can be fed as shown... Figure 6 The defective tray 3 that is inserted into the detection hole 2063 but cannot be connected to the detection probe 2061 is sent separately into the third output channel. Thus, this utility model can further refine the sorting of defective products with different problems, which is conducive to subsequent product problem analysis and detailed statistics of defect rate.

[0039] like Figure 4 As shown, in this embodiment, the horizontal mounting base 101 of the sorting mechanism 1 is equipped with multiple horizontal positioning sensors 106, and the horizontal moving base 102 of the sorting mechanism 1 is equipped with a horizontal movement sensing plate 1022. When the horizontal movement sensing plate 1022 moves with the horizontal moving base 102 to the upper side of any horizontal positioning sensor 106, the horizontal positioning sensor 106 sends a signal to the equipment control system to stop the horizontal moving base 102 from moving. At this time, the tray 3 at the lower end of the horizontal moving base 102 is located above the corresponding output channel. This utility model can set a corresponding number and position of horizontal positioning sensors 106 according to the number of output channels. The horizontal positioning sensors 106 and the horizontal movement sensing plate 1022 are both known technologies in the art and are commercially available products.

[0040] like Figure 4 As shown in this embodiment, the horizontal mounting base 101 is provided with a cable carrier 105 for carrying various cables. One end of the cable carrier 105 is fixedly connected to the cable carrier connecting plate 1023 located on the upper end of the horizontal moving base 102, and the other end is fixedly mounted on the horizontal mounting base 101.

[0041] This utility model can employ different transmission devices 7 according to actual needs, such as Figure 1 As shown, in one embodiment of this utility model, the transmission device 7 uses a turntable for transmission, and a servo motor for driving the turntable to rotate is provided on the lower side of the turntable. Figure 5 As shown, the outer support 201 of the continuity detection mechanism 2 is located outside the turntable, and the inner support 207 is located below the turntable. This turntable transmission can save installation space, and other workstation mechanisms can be arranged as needed along the circumference of the turntable. Figure 1As shown, this utility model can be integrated onto a mobile frame 5. The lower end of the mobile frame 5 is equipped with self-locking wheels to enable the overall movement of this utility model, allowing it to be pushed to a suitable position according to actual needs. In another embodiment of this utility model, a traditional conveyor belt can be used to achieve point-to-point transport between the continuity detection station and the sorting station.

[0042] The working principle of this utility model is as follows:

[0043] The present invention includes the following steps in operation:

[0044] Step 1: Place the basin stand 3 in the basin stand base 701 of the transmission device 7.

[0045] Step 2: The transmission device 7 delivers the basin frame 3 inside the basin frame seat 701 to the continuity test station.

[0046] Step 3: As Figure 3 As shown, the clamping cylinder 202 in the continuity detection mechanism 2 starts and drives the clamping plate 203 to descend and clamp the basin frame 3 inside the fixed basin frame seat 701.

[0047] Step Four: As Figures 4-5 As shown, the lower lifting cylinder 204 in the continuity detection mechanism 2 starts to drive the detection plate 205 to rise, and causes the detection end seat 206 on the detection plate 205 to insert into the... Figure 3 Continuity testing is performed on the basin frame terminal block 301 on the side wall of the basin frame 3 shown.

[0048] In this step, this invention can detect only qualified and unqualified basin racks 3, and then sort them through the sorting mechanism 1, or it can be as follows: Figures 6-7 The test revealed three types of basin frames 3: a qualified basin frame 3, a basin frame 3 with an unqualified terminal 301 position, and a basin frame 3 with unqualified electrical conductivity. The basin frame 3 with an unqualified terminal 301 position is shown below. Figure 7 As shown, this is a signal transmission device system generated by conductive sheet 2062, the principle of which can be found in CN215728729U.

[0049] Step 5: Based on the detection results from Step 4, the equipment system controls the sorting mechanism 1 to send different tray racks 3 into their corresponding output channels. The sorting mechanism 1 utilizes the clamping claw 1041 at the lower end of the clamping cylinder 104 to insert into the tray rack through hole 302 in the middle of the tray rack 3 and open to clamp, thus transferring the tray rack 3. Simultaneously... Figure 4 As shown, the sorting mechanism 1 has multiple horizontal positioning sensors 106 on its horizontal mounting base 101, each corresponding to a different output channel, to ensure that the tray rack 3 can accurately stop above the input end of the corresponding output channel.
