Description

Technical Field

[0001] This utility model relates to the field of resistance detection, specifically an automatic resistance detection device. Background Technology

[0002] Resistance testing of electronic components or products is involved in many fields, including automotive, new energy, medical electronics, communication equipment, aerospace, defense electronics, and industrial control and automation. Previously, resistance testing was mostly performed manually using resistance testers, or with single-function devices such as resistance meters. However, these methods generally only allow for resistance testing of a single product and are not suitable for testing large quantities of electronic components or products.

[0003] With technological advancements, some automated resistance testing devices have emerged in the existing technology. For example, patent CN211785799U discloses a scanning probe resistance testing system, which uses a computer-controlled three-dimensional displacement stage to locate the sample test points and control the contact and disconnection between the probe and the sample, thereby enabling the measurement of a large number of samples. However, this device does not consider how resistance testing can be integrated with product loading and unloading, and its automation level needs further improvement. In addition, although the probe combination of this device can adopt various forms as needed, the probe spacing cannot be flexibly adjusted according to product specifications. Utility Model Content

Meanwhile, the two detection probes in the probe mechanism can flexibly adjust the spacing according to the product situation to meet the resistance testing needs of products of different specifications.

[0019] 3. The feeding mechanism of this utility model is equipped with a feeding camera. During feeding and clamping, the feeding camera simultaneously obtains information such as product model and detection point angle and transmits it to the equipment control system, so that subsequent adjustment of detection turntable angle and detection probe spacing can accurately match the product model.

[0020] 4. After the product enters the detection chamber module, the present invention first uses the detection turntable in the detection transfer mechanism to place in the opening at the bottom of the resistance detection chamber to seal the resistance detection chamber. Then, the sealing cylinder in the detection chamber module supports and locks the height of the detection lifting plate in the detection transfer mechanism to ensure that the resistance detection chamber is securely sealed, thereby ensuring detection safety.

[0021] 5. In addition to flexibly adjusting the distance between the two detection probes using the probe pitch-changing component, the probe mechanism of this utility model can also flexibly adjust the position and height of the detection probes using the probe moving module and the probe lifting module to ensure detection coordination with other mechanisms.

[0022] 6. In addition to realizing automatic product loading, inspection and unloading, this utility model can also realize automatic transfer of material boxes.

Figure 9 As shown, the clamping block assembly, along with the product 10, is conveyed to the area below the detection chamber module 4 via the detection transfer bracket 302, and the product 10 is then fed into the detection chamber module 4 via the clamping block assembly; as Figures 10-11 As shown, the probe mechanism 5 includes a movable detection probe 507, and during detection, the detection probe 507 enters the detection cavity module 4 and contacts the product 10. After the material box 102 on the loading cart 1 is empty, it is sent to the unloading cart 9 through the material box transfer mechanism 8. The product 10 that has been tested first descends through the clamping block assembly to get out of the detection cavity module 4, and then is sent to the underside of the unloading mechanism 7 through the detection transfer bracket 302, and then sent to the empty material box 102 on the unloading cart 9 through the unloading mechanism 7. In addition, when this utility model is working, an empty material box 102 can be set separately on the unloading cart 9 to receive the first few products 10 that have completed resistance testing. When the first material box 102 on the loading cart 1 is empty, the material box 102 is sent to the unloading cart 9 through the material box transfer mechanism 8 and stacked on the upper side of the material box 102 set separately on the unloading cart 9.

[0048] like Figures 1-2 As shown, in this embodiment, the feeding mechanism 2, the detection and transfer mechanism 3, the detection cavity module 4, the probe mechanism 5, the unloading mechanism 7, and the material box transfer mechanism 8 are all mounted on a single equipment frame 11. The equipment frame 11 has a feeding station for the feeding cart 1 to enter and exit, and an unloading station for the unloading cart 9 to enter and exit, located on the side near the material box transfer mechanism 8.

[0049] like Figure 3 As shown, in this embodiment, the loading cart 1 and unloading cart 9 have the same structure, both including a mobile cart body 101. Support plates 1011 supporting material boxes 102 are provided on both sides of the mobile cart body 101. Limiting guide plates 1012 defining the position of the material boxes 102 are provided at both ends of the support plates 1011. Both the loading and unloading stations of the equipment frame 11 are equipped with material box lifting modules 103, and the material box lifting module 103 has a lifting slider connected to a lifting fork 104. When this invention is in operation, the lifting fork 104 is driven by the material box lifting module 103 to rise between the two support plates 1011 and contact the material boxes 102, thereby raising each material box 102 to a set height. The material box lifting module 103 can adopt a suitable structure as needed, such as a rodless cylinder with a slider serving as the lifting slider, or a motor screw and nut structure, where the screw is driven to rotate by a motor, and the nut is fitted onto the screw and fixedly connected to the lifting slider.

[0050] like Figure 4 As shown, in this embodiment, the feeding mechanism 2 includes a feeding frame 201, a feeding transverse module 202, a feeding lifting module 204, a feeding longitudinal module 206, a feeding gripper 210, and a feeding camera 208.

The second mounting plate 2072 is provided with a loading camera 208. The loading camera 208 is a technology known in the art and is a commercially available product.

[0052] When this utility model is in operation, the loading gripper 210 first moves to the top of the loading cart 1. Then, the loading gripper 210 adjusts its position through the loading transverse module 202 and the loading longitudinal module 206 to align with the product 10 to be clamped. After alignment, the loading gripper 210 descends and clamps the corresponding product 10. Before each gripping, the loading camera 208 will take pictures of the product 10 model, detection point angle, and other information and automatically record them to the equipment control system. In addition, in order to ensure the shooting quality, a shooting light source can be set at a suitable position on the second mounting plate 2072 as needed. This is a well-known technology in the field. After clamping, the loading gripper 210 lifts the product 10 to a set height. Then, the loading transverse module 202 drives the loading gripper 210 to move above the clamping block assembly located at the input end of the detection and transfer mechanism 3. The loading gripper 210 is then adjusted in position again by the loading transverse module 202 and the loading longitudinal module 206 to align with the clamping block assembly. Finally, the loading gripper 210 descends and inputs the product 10 into the open clamping block assembly. Additionally, as... Figure 3 As shown, since the products 10 in the material box 102 are arranged in a matrix, the feeding mechanism 2 and the unloading mechanism 7 of this utility model can both be programmed to set the moving paths of the feeding gripper 210 and the unloading gripper 709 according to the matrix arrangement spacing of the products 10.

[0053] like Figures 6-7 As shown, in this embodiment, the detection transfer mechanism 3 includes a detection transfer module 301, and the detection transfer bracket 302 is driven to move by the detection transfer module 301. The detection transfer bracket 302 has a detection lifting device 303 inside and a detection lifting plate 304 on its upper side. The detection lifting plate 304 is driven to rise and fall by the detection lifting device 303. Figure 6 As shown, each corner of the detection lifting plate 304 is provided with a lifting guide rod 3041 to ensure vertical lifting. The lower end of the lifting guide rod 3041 passes through a guide sleeve provided on the upper surface of the detection transfer bracket 302. A detection rotation device 305 is fixedly provided on the lower side of the detection lifting plate 304, and a detection turntable 306 is provided on the upper side.

[0054] In operation, after the clamping block assembly clamps the product 10, the detection turntable 306 is first driven to rotate by the detection rotation device 305 to adjust the angle of the product 10. The detection rotation device 305 controls the rotation angle of the detection turntable 306 based on information such as the product model number captured by the loading camera 208. Then... Figure 9 As shown, the detection transfer bracket 302 is driven to move below the detection cavity module 4 by the detection transfer module 301, and then the detection lifting plate 304 is driven to rise to a set height by the detection lifting device 303, so that the clamping block assembly and the product 10 enter the detection cavity module 4, and then... Figure 11 As shown, the detection probe 507 in the probe mechanism 5 enters the detection cavity module 4 and contacts the product 10 to achieve resistance detection.

[0055] like Figure 2 As shown in this embodiment, both ends of the detection and transfer module 301 are provided with clamping mechanisms 6. The clamping mechanism 6 located at the input end of the detection and transfer module 301 is used to open the clamping block assembly to realize the input of product 10, and the clamping mechanism 6 located at the output end of the detection and transfer module 301 is used to open the clamping block assembly to realize the output of product 10.

[0056] like Figure 7 As shown, in this embodiment, the clamping block assembly includes a fixed clamping block 309, a floating clamping block 310, and a clamping floating seat 307. The fixed clamping block 309 is fixedly mounted on the detection turntable 306, the clamping floating seat 307 is slidably connected to the detection turntable 306, and the floating clamping block 310 is fixedly mounted on the clamping floating seat 307. The rear end of the floating clamping block 310 is provided with an elastic floating shaft 311 connected to a mounting seat 312 on the detection turntable 306. A spring is fitted on the elastic floating shaft 311, and the spring is located between the floating clamping block 310 and the mounting seat 312. The rear end of the elastic floating shaft 311 passes through the mounting seat 312 and is provided with a limiting block to prevent disengagement. The clamping mechanism 6 includes a movable clamping block 603, and the clamping floating seat 307 is driven to move by the clamping block 603, thereby causing the floating clamping block 310 to achieve an opening and closing action with the fixed clamping block 309. Through the above structural design, this utility model can flexibly adjust the degree of opening and closing between the floating clamping block 310 and the fixed clamping block 309, thereby meeting the clamping and positioning needs of products 10 with different diameter specifications. At the same time, the spring on the elastic floating shaft 311 can ensure the clamping force of the product 10.

[0057] like Figure 7 As shown, in this embodiment, the detection turntable 306 is provided with a floating seat slide rail 308, and the lower side of the clamping floating seat 307 is provided with a floating seat slider that cooperates with the floating seat slide rail 308.

[0058] like Figure 7 As shown, in this embodiment, the clamping floating seat 307 is provided with a driving block 3071 on the side near the opening clamping mechanism 6, and the opening clamping block 603 abuts against the driving block 3071 to drive the clamping floating seat 307 together with the floating clamping block 310 to move.

The lower side of the detection platform 402 is provided with multiple support rods that are fixedly connected to the equipment frame 11. The resistance detection cavity 401 is located on the detection platform 402. The upper end of the resistance detection cavity 401 is provided with a detection cavity inlet 4011 for the insertion of the detection probe 507. The bottom plate 4012 of the resistance detection cavity 401 is provided with an opening for the input of the product 10. The area of ​​the opening is equal to the area of ​​the detection turntable 306. During detection, the detection turntable 306 rises and is placed in the opening, thereby forming a closed cavity in the resistance detection cavity 401.

[0061] like Figure 9 As shown, in this embodiment, a sealing cylinder 403 is provided on the lower side of the detection platform 402. After the detection lifting plate 304 rises to a set height, the lower side of the detection lifting plate 304 is supported by the cylinder rod extending from the sealing cylinder 403 to achieve height locking. This prevents the detection turntable 306 from disengaging from the opening on the lower side of the resistance detection cavity 401 due to impact forces generated by unexpected situations. This allows a solid and reliable sealed space to be formed inside the resistance detection cavity 401, ensuring detection safety. In this embodiment, the sealing cylinder 403 can be an explosion-proof cylinder, which is a commercially available product.

In this embodiment, the probe moving module 502 and the probe lifting module 504 can employ a rodless cylinder or a motor screw and nut structure.

[0063] like Figure 11 As shown, in this embodiment, the probe pitch-changing assembly 506 includes a drive wheel 5061, a pitch-changing transmission belt 5062, a driven wheel 5063, and two pitch-changing adjustment plates 5064. The drive wheel 5061 and the driven wheel 5063 are both mounted on the probe lifting seat 505 and connected to each other via the pitch-changing transmission belt 5062. The two pitch-changing adjustment plates 5064 are slidably connected to the probe lifting seat 505. One pitch-changing adjustment plate 5064 is fixedly connected to the upper side of the pitch-changing transmission belt 5062 via a first connecting block 5066, and the other pitch-changing adjustment plate 5064 is fixedly connected to the lower side of the pitch-changing transmission belt 5062 via a second connecting block 5067. Two detection probes 507 are respectively mounted on the pitch-changing adjustment plates 5064 on the corresponding sides.

[0064] In operation, when product 10 is fed into the resistance detection cavity 401 of the detection cavity module 4 via the clamping block assembly in the detection transfer mechanism 3, the probe moving module 502 in the probe mechanism 5 first drives the detection probe 507 to move above the detection cavity inlet 4011 on the upper side of the resistance detection cavity 401. Then, the two detection probes 507 adjust their spacing according to the product 10 model and other information captured by the loading camera 208. Figure 11 As shown, when the upper side of the variable-pitch transmission belt 5062 moves to the left, the first connecting block 5066 also moves to the left. Simultaneously, the lower side of the variable-pitch transmission belt 5062 moves to the right, driving the second connecting block 5067 to move to the right as well. This achieves the closing action of the first connecting block 5066 and the second connecting block 5067, which in turn achieves the closing action of the two variable-pitch adjustment plates 5064 and the two detection probes 507. After the distance between the two detection probes 507 is adjusted, the probe lifting module 504 drives the detection probes 507 to descend and enter the resistance detection cavity 401 to complete the resistance detection. The use of the detection probes 507 to detect resistance is a well-known technology in the art, for example, see patent CN211785799U.

[0065] like Figure 10 As shown, in this embodiment, the probe lifting seat 505 is provided with an active wheel drive device 5068 for driving the active wheel 5061 to rotate, thereby driving the variable pitch transmission belt 5062 to move. The active wheel drive device 5068 can be a geared motor. In addition, the probe lifting seat 505 can be provided with a displacement sensor as needed to detect the displacement of the two variable pitch adjustment plates 5064, thereby realizing the variable pitch control of the two detection probes 507. The displacement sensor is a commercially available product.

[0066] like Figure 11 As shown in this embodiment, the probe lifting seat 505 is provided with an adjusting slide rail 5065, and the variable pitch adjusting plate 5064 is provided with an adjusting slider that cooperates with the adjusting slide rail 5065 on the corresponding side.

[0067] like Figure 12 As shown, in this embodiment, the unloading mechanism 7 includes an unloading bracket 701, an unloading transverse module 702, an unloading lifting module 704, an unloading longitudinal module 706, and an unloading gripper 709. The unloading bracket 701 is mounted on the equipment frame 11, the unloading transverse module 702 is mounted on the unloading bracket 701, and the unloading transverse module 702 is provided with an unloading transverse seat 703. The unloading lifting module 704 is mounted on the unloading transverse seat 703, and the unloading lifting module 704 is provided with an unloading lifting seat 705. The unloading longitudinal module 706 is located below the unloading lifting seat 705, and the unloading longitudinal module 706 is provided with an unloading longitudinal seat 707. The unloading longitudinal seat 707 is provided with an unloading gripper cylinder 708, and the unloading gripper cylinder 708 is provided with an openable and closeable unloading gripper 709. The unloading mechanism 7 works on the same principle as the loading mechanism 1, except that the unloading mechanism 7 does not have a camera for photographing the product 10.

[0068] like Figure 13 As shown, in this embodiment, the bin transfer mechanism 8 includes a mounting bracket 801, a bin transfer module 802, a bin transfer seat 803, a bin clamping cylinder 804, and bin grippers 805. The mounting bracket 801 is mounted on the equipment frame 11, the bin transfer module 802 is mounted on the mounting bracket 801, and the bin transfer seat 803 is driven to move by the bin transfer module 802. The bin clamping cylinder 804 is located in the bin transfer seat 803, and the two bin grippers 805 are driven to open and close by the bin clamping cylinder 804. The bin transfer module 802 can be a rodless cylinder or a motor screw and nut structure, and it is equipped with a conveying moving block.

[0069] like Figure 13As shown in this embodiment, the mounting bracket 801 has the material box transfer module 802 on one side and the transfer slide rail 806 on the other side. The material box transfer seat 803 is connected to the conveying moving block on one side of the material box transfer module 802 and has a transfer slider on the other side that slides in cooperation with the transfer slide rail 806.

[0070] In operation, when the uppermost material box 102 on the loading trolley 1 is empty, the material box transfer seat 803 moves above the loading trolley 1, and the two material box grippers 805 are in an open state. Then, the lifting forks 104 corresponding to the loading trolley 1 drive each material box 102 to rise to a set height, so that the uppermost empty material box 102 enters between the two material box grippers 805, and at the same time, the second layer of material boxes 102 reaches the loading height. Then, the two material box grippers 805 close to clamp the uppermost empty material box 102, and move it above the unloading trolley 9 through the material box transfer seat 803. Then, the lifting fork 104 corresponding to the unloading trolley 9 first rises to a set height so that the top layer of the hopper 102 filled with the inspected product 10 contacts the bottom of the transferred empty hopper 102. Then, the two hopper grippers 805 open to release the empty hopper 102, and the lifting fork 104 corresponding to the unloading trolley 9 descends so that the top layer of the transferred empty hopper 102 falls to the receiving height to wait for the inspected product 10 to be loaded. After the empty hopper 102 descends, the hopper grippers 805 move away from the position above the unloading trolley 9 to avoid affecting the unloading movement of the inspected product 10.

[0071] Once the material trolley 9 is filled with the material box 102, it exits the unloading station of the equipment frame 11. At the same time, the material loading trolley 1 is empty of the material box 102 and also exits the loading station of the equipment frame 11. At this time, it can be pushed into the unloading station as an empty unloading trolley.

[0072] The working principle of this utility model is as follows:

[0073] When this utility model is in operation, firstly as follows: Figure 1 As shown, the loading cart 1, filled with material bin 102, is pushed into the loading station on one side of the equipment frame 11, and the material bin 102 is filled with the products 10 to be inspected. Meanwhile, the unloading cart 9 is pushed into the unloading station on one side of the equipment frame 11. At this time, an empty material bin 102 can be set on the unloading cart 9 to hold the first few products 10 that have been inspected.

[0074] After the loading trolley 1 is input, the corresponding lifting forks 104 on the loading trolley 1 drive each material box 102 to rise, so that the uppermost material box 102 reaches the set loading height. Then, the loading mechanism 2 picks up the product 10 from the uppermost material box 102 of the loading trolley 1 and sends it to the clamping block assembly in the detection and transfer mechanism 3. When the product 10 is picked up, the loading camera 208 simultaneously captures information such as the product 10 model and transmits it to the equipment control system.

[0075] The present invention includes the following steps for resistance detection:

[0076] Step 1: The detection transfer bracket 302 in the detection transfer mechanism 3 is first driven to the input end by the detection transfer module 301, and the clamping block assembly on the detection transfer bracket 302 is opened by the clamping mechanism 6 located at the input end. Then the feeding mechanism 2 puts the product to be tested 10 into the clamping block assembly.

[0077] In this step, such as Figure 7 As shown, the clamping block 603 in the clamping mechanism 6 is driven to move by the clamping drive device 602, thereby causing the floating clamping block 310 in the clamping block assembly to move and open, and then the product 10 is placed between the fixed clamping block 309 and the floating clamping block 310. The rear end of the floating clamping block 310 is provided with an elastic floating shaft 311 with a spring, so that the floating clamping block 310 and the fixed clamping block 309 can cooperate to meet the clamping and fixing needs of products 10 with different diameter specifications. At the same time, the spring can ensure the clamping force of the product 10 to prevent the product 10 from moving during the transfer process.

[0078] Step 2: After product 10 is placed into the clamping block assembly, the detection rotation device 305 in the detection transfer mechanism 3 first controls the detection turntable 306 to rotate at a set angle according to the product 10 model and other information captured by the loading camera 208, so as to ensure that the detection point on the upper end of product 10 rotates to the detection position.

[0079] Step 3: After product 10 has completed angle adjustment, as follows: Figure 9 As shown, the detection transfer bracket 302 drives the clamping block assembly and product 10 to move to the bottom of the detection cavity module 4. Then, the detection lifting device 303 in the detection transfer mechanism 3 drives the detection lifting plate 304 to rise to the set height, while simultaneously driving the clamping block assembly and product 10 to rise and enter the resistance detection cavity 401 of the detection cavity module 4.

[0080] In this step, such as Figure 9 As shown, after the detection turntable 306 in the detection transfer mechanism 3 rises, it is placed in the opening at the bottom of the resistance detection cavity 401, thereby forming a closed structure in the resistance detection cavity 401.

[0081] In addition, in this step, a height detection sensor can be installed on the lower side of the detection platform 402 as needed to ensure that the rising height of the detection lifting plate 304 and the detection turntable 306 meets the requirements. The height detection sensor is a commercially available product.

[0082] Step Four: As Figure 9 As shown, the cylinder rod of the closed cylinder 403 on the lower side of the detection platform 402 extends to support and lock the height of the detection lifting plate 304, thereby ensuring that the resistance detection cavity 401 is securely sealed.

[0083] Step 5: As Figures 10-11 As shown, the detection probe 507 in the probe mechanism 5 is first driven to move above the detection cavity inlet 4011 on the upper side of the resistance detection cavity 401 by the probe moving module 502. Then, the probe pitching component 506 in the probe mechanism 5 adjusts the distance between the two detection probes 507 according to the product model and other information captured by the loading camera 208. After the adjustment is completed, the detection probe 507 descends into the resistance detection cavity 401 and contacts the product 10 to realize resistance detection.

[0084] Step Six: After the product 10 is inspected, the inspection probe 507 rises, and at the same time, the cylinder rod of the closed cylinder 403 in the inspection cavity module 4 retracts and unlocks. Then, the inspection lifting device 303 in the inspection transfer mechanism 3 drives the inspection lifting plate 304, together with the clamping block assembly and the product 10, to descend to the set height to detach from the inspection cavity module 4.

[0085] Step 7: The product 10 detached from the detection chamber module 4 is sent to the output end of the detection transfer module 301 through the detection transfer bracket 302, and the floating clamp 310 in the clamping block assembly is opened by the clamping mechanism 6 located at the output end. Then the unloading mechanism 7 takes away the product 10 that has completed the detection, thereby completing the entire detection process.

[0086] Other examples Figure 1 As shown, this utility model can also realize the transfer and circulation of material bins 102. When the uppermost material bin 102 on the loading cart 1 is empty, it is sent to the unloading cart 9 through the material bin transfer mechanism 8, and then reloaded with the products 10 that have completed inspection, which are input by the unloading mechanism 7. When the unloading cart 9 is full of material bins 102, it exits the unloading station of the equipment frame 11. At the same time, the loading cart 1 is empty of material bins 102 and also exits the loading station of the equipment frame 11. At this time, it can be pushed into the unloading station as an empty unloading cart as needed.

[0087] One application example of this invention is the resistance detection of a heater, and this invention can be applied to the detection needs of heaters with different diameter specifications.
