[0050] In light of the aforementioned deficiencies in existing resistance test stations for electronic atomizers, the applicant, drawing on years of extensive practical experience and expertise in the design and manufacture of such products, combined with applied theory, has actively engaged in research and innovation, hoping to develop a technology that addresses these deficiencies and make resistance test stations more practical. Through continuous research and design, repeated prototype production, and improvements, the present invention has been developed, which demonstrates its proven practical value.

[0051] Please refer to Figures 1 to 6 The present invention provides a resistance testing station, comprising:

[0052] The test stand 1 is provided with a positioning plate 11, and a plurality of positioning test through holes 101 are arranged on the positioning plate 11; generally, the number of positioning test through holes 101 on a positioning plate 11 is greater than 5. In this embodiment, the number of positioning test through holes 101 on a positioning plate 11 is 16.

[0053] A plurality of resistance test modules 2, and a plurality of resistance test modules 2 correspond one to one with the positions of the positioning test through-holes 101, that is, the number of resistance test modules 2 is the same as the number of positioning test through-holes 101; the resistance test module 2 blocks the bottom opening of the positioning test through-hole 101, and extends a test probe assembly toward the positioning test through-hole 101; the test probe assembly contacts the bottom end of the workpiece so as to form a detection circuit to detect the resistance of the heating wire in the workpiece. The workpiece is a semi-finished electronic atomizer, that is, the bottom end of the workpiece exposes the conductive part to contact the test probe assembly. The manipulator 3 can be a four-axis manipulator or a six-axis manipulator, which is used to grab a plurality of workpieces and insert them into the positioning test through-holes 101 at the same time. Of course, the workpiece can also be other electrical appliances, components, etc. that need to detect resistance.

[0054] In this embodiment, the manipulator can grab multiple workpieces at a time, and each resistance testing module 2 can respectively detect the workpieces inserted into the positioning test through hole 101, thereby being able to detect the resistance of the heating wires in multiple workpieces at a time, effectively improving the detection efficiency.

[0055] It should also be noted that resistance test module 2 blocks the bottom opening of positioning test hole 101, thereby preventing the workpiece from falling through positioning test hole 101. It should also be noted that positioning test hole 101 can be elliptical, parallelogram, square, or other shapes. Generally, when a workpiece is inserted into positioning test hole 101, it cannot rotate about the centerline of positioning test hole 101, thereby ensuring that the test probe assembly can accurately contact the conductive portion at the bottom end of the workpiece.

[0056] Optionally, a positioning groove 102 is defined at the bottom of the positioning plate 11, into which the resistance testing module 2 can be removably mounted. The provision of the positioning groove 102 effectively simplifies the assembly steps of the resistance testing module 2. Specifically, the resistance testing module 2 can be simply inserted into the positioning groove 102, then moved along the positioning groove 102 to a desired position, and then secured. Typically, threaded fasteners are screwed into the positioning plate 11 to secure the resistance testing module 2.

[0057] Optionally, the positioning test through hole 101 includes a guide hole section 1011, a positioning hole section 1012 and a tail hole section 1013 arranged in sequence. Figure 4 As shown, the guide hole section 1011 is trumpet-shaped and is provided with a guide surface, so that the end of the workpiece can better enter the positioning test through hole 101; the shape of the positioning hole section 1012 matches the shape of the workpiece, so that it can accurately position the workpiece; the aperture of the tail hole section 1013 is smaller than the aperture of the positioning hole section 1012, and a positioning step 1014 is formed between the tail hole section 1013 and the positioning hole section 1012; the positioning step 1014 supports the workpiece to prevent the workpiece from exerting excessive pressure on the test probe assembly.

[0058] The test probe assembly includes a first probe 21 and a second probe 22 spaced apart from each other. Both the first probe 21 and the second probe 22 extend into the positioning hole section 1012 along the tail hole section 1013. Generally, the first probe 21 and the second probe 22 connect to the heating wire, thereby forming a test circuit and detecting the resistance of the heating wire in the workpiece.

[0059] Optionally, the manipulator 3 is provided with a gripper assembly; the gripper assembly includes a horizontal plate 31 and individual grippers 32 arranged in an array on the horizontal plate 31. The number of individual grippers 32 is equal to the number of positioning test holes 101. The positions of the individual grippers 32 correspond to the positions of the positioning test holes 101, i.e., the center-to-center distance between two adjacent individual grippers 32 is equal to the center-to-center distance between two adjacent positioning test holes 101. The individual grippers 32 include two opposing clamping arms 321 and a clamping cylinder 322 for driving the two clamping arms 321 to clamp a workpiece.

[0060] Optionally, the resistance testing station further includes a conveyor line 4 for conveying the carrier, with the manipulator 3 mounted on top of the conveyor line 4. A positioning plate 11 is positioned adjacent to the conveyor line 4, with the positioning plate 11 extending parallel to the conveying direction of the conveyor line 4. Positioning the positioning plate 11 adjacent to the conveyor line 4 reduces the travel distance of the manipulator 3, thereby shortening the workpiece inspection cycle.

[0061] Optionally, the conveyor line 4 includes a first conveyor belt 41 and a second conveyor belt 42 arranged in parallel; a blocking device 5 is provided between the first conveyor belt 41 and the second conveyor belt 42 for blocking a carrier plate. The carrier plate is used to support and transfer workpieces. The blocking device 5 includes a blocking component and a lifting device for driving the blocking component to rise and fall in a direction perpendicular to the conveying surface of the conveyor belts. Specifically, when it is necessary to block the carrier plate, the blocking device 5 is raised by the lifting device, so that the blocking device 5 can position and block the carrier plate; when it is not necessary to block the carrier plate, the blocking device 5 is lowered by the lifting device, so that the highest point of the blocking device 5 is lower than the bottom surface of the carrier plate.

[0062] In another specific embodiment, the resistance testing station also includes a blocking device 5 for stopping the conveyor line 4; the blocking device 5 includes a rotating cylinder 51, a mounting base 52 fixedly connected to the driving part of the rotating cylinder 51, and an L-shaped blocking block 53 rotatably mounted on the mounting base 52.

[0063] like Figure 2 , the L-shaped blocking block 53 has a blocking long arm 531 and a avoiding short arm 532; when moving from the upper left to the lower right, the rotating cylinder 51 drives the L-shaped blocking block 53 to rotate to the first angle, that is, Figure 2 At the position of the middle L-shaped blocking block 53, the side of the carrier can press on the blocking long arm 531, and at this time the avoiding short arm 532 presses down on the mounting seat 52 to stop the carrier.

[0064] When the carrier plate does not need to be stopped, the rotating cylinder 51 drives the L-shaped blocking block 53 to rotate to the second angle, that is, Figure 2 The middle L-shaped blocking block 53 rotates 180°. At this time, the avoidance short arm 532 is located on the left side of the blocking long arm 531. The side of the loading plate can be pressed on the blocking long arm 531, so that the avoidance short arm 532 is tilted upward, and the blocking long arm 531 does not block the loading plate. The first angle and the second angle differ by 180°.

[0065] In this embodiment, by changing the position of the L-shaped stopper 53, the effect of stopping or releasing the load plate can be achieved, without the need for a lifting device. This further optimizes the structure and facilitates the optimization of the resistance testing station. Furthermore, the L-shaped stopper 53 is also stronger and less susceptible to deformation caused by impacts from the load plate.

[0066] Optionally, the blocking device 5 further includes an elastic member 54, one end of which is connected to the mounting seat 52 and the other end is connected to the bottom surface of the short arm 532. In the absence of external force, the elastic force of the elastic member 54 causes the top of the long blocking arm 531 to be higher than the conveying surface of the conveyor line 4. After the carrier passes the top of the blocking device 5, the elastic member 54 resets the L-shaped blocking block 53.

[0067] Optionally, a roller 55 is provided at the top end of the long arm 531 that blocks the short arm 532 from being avoided, so as to avoid scratching the bottom surface of the carrier plate.

[0068] Optionally, the mounting seat 52 includes a first side plate 521, a second side plate 522 and a front end baffle 523. The first side plate 521 and the second side plate 522 are arranged relative to each other to form a mounting groove. A rotating shaft 56 is provided in the mounting groove. The L-shaped blocking block 53 can be rotatably mounted on the rotating shaft 56; the front end baffle 523 has a stopping surface for blocking and avoiding the short arm 532.

[0069] Finally, it should be noted that although the above embodiments have been described in the specification and drawings of this application, this does not limit the scope of patent protection of this application. All technical solutions generated by replacing or modifying equivalent structures or equivalent processes based on the essential concepts of this application using the contents recorded in the specification and drawings of this application, as well as directly or indirectly implementing the technical solutions of the above embodiments in other related technical fields, are included in the scope of patent protection of this application.
