Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0019] The present invention will be further described below in conjunction with the embodiments.

[0020] Example: Reference Figure 1-Figure 7, a semi-automatic needle-stitching rubber-coated product performance testing equipment includes a workbench 1 and a clamping assembly for clamping needles, which includes a screening table 2 installed on the workbench 1, a mounting plate 4 is elastically installed on the screening table 2, two clamping plates 5 are rotatably installed on the mounting plate 4, and needles are placed on the clamping plates 5, and reinforcing plates 21 are rotatably installed on the two clamping plates 5, and arc grooves are provided on the outer walls of the two clamping plates 5 on the sides close to each other, and a bracket is fixedly installed on the mounting plate 4, and the clamping plates 5 are rotatably installed on the bracket, and an inclined surface is provided at the bottom of the clamping plates 5, and an adjusting plate 24 is slidably installed on the inclined surface, and a slide plate 26 is rotatably connected to the end of the adjusting plate 24 away from the clamping plate 5, and the slide plate 26 is slidably connected to the top wall of the mounting plate 4, and the mounting plate 4 is provided with an electric push rod for driving the slide plate 26 to slide, and when the mounting plate 4 slides in the direction of the arc groove, the clamping plate 5 connected thereto rotates in the direction of the mounting plate 4, and a screening plate is provided on the outer wall of one side of the screening table 2. Slot 18, a screening hole 16 is provided on the top wall of the screening platform 2, and a screening plate 17 is rotatably installed in the screening hole 16, and a coil spring is provided at the rotating connection of the screening plate 17, a transmission plate 14 is fixedly installed on one side of the first detection frame 7, a reversing plate 15 is fixedly installed on the bottom wall of the transmission plate 14, and the screening plate 17 is squeezed to rotate when the reversing plate 15 moves downward, an elastic rod is connected between the bottom wall of the mounting plate 4 and the screening platform 2, an auxiliary air bag 20 is fixedly installed on the bottom wall of the mounting plate 4, a reinforcement groove is provided on the top wall of the splint 5, a reinforcement plate 21 is rotatably installed in the reinforcement groove, a flip air bag 22 is fixedly installed in the reinforcement groove, the flip air bag 22 located on the same splint 5 is commonly connected with a shunt pipe 23, and the shunt pipe 23 and the auxiliary air bag 20 are connected, a gas relief valve is provided on the shunt pipe 23, and a pressure switch is provided on the gas relief valve, and when the adjusting plate 24 slides in the direction of the shunt pipe 23, the pressure switch is squeezed to open the gas relief valve.

[0021] In order to ensure the accuracy of the detection, a clamping component is installed on the workbench 1, such as Figure 6 As shown, the stitching needle is clamped between two clamping plates 5, and an arc groove is provided on the side wall of the clamping plate 5, which can adapt to the outer contour of the stitching needle to a certain extent. Of course, the contour of the groove is modified according to the actual stitching needle contour without affecting the clamping result.

[0022] like Figure 3 As shown, when the first detection frame 7 moves down to detect the stitching needle, it will squeeze the mounting plate 4 to move down, and then the second detection frame 9 will translate and gradually approach the stitching needle. When the mounting plate 4 moves down, the auxiliary airbag 20 is squeezed and contracted, and the air in the auxiliary airbag 20 enters the flip airbag 22 through the shunt pipe 23. The flip airbag 22 expands and squeezes the reinforcement plate 21 to rotate. The number of reinforcement plates 21 on the two clamping plates 5 is the same, and the positions are symmetrical, so as to improve the stability of the detection.

[0023] A one-way valve is provided at the connection between the auxiliary airbag 20 and the shunt pipe 23 , and an air inlet hole is provided on the auxiliary airbag 20 , which is also provided with a one-way valve.

[0024] like Figure 6 and Figure 7 As shown, a reinforcing plate 21 is provided on the clamping plate 5, wherein a coil spring is provided at the rotation connection of the reinforcing plate 21 to help it reset.

[0025] The clamping plate 5 is mounted on the mounting plate 4 in a rotating manner, so that the clamping plate 5 not only has a clamping function, but also has a guiding function after being rotated and tilted. Figure 7 As shown, two slide plates 26 are driven to slide on the mounting plate 4 by two electric push rods (not shown in the figure), and the adjusting plate 24 is rotatably connected above the slide plate 26. The adjusting plate 24 slides along the inclined surface at the bottom of the corresponding clamp plate 5. When the slide plate 26 slides in the direction of the stitching needle, the clamp plate 5 is deflected, and in the process of sliding the slide plate 26, the pressure switch on the shunt pipe 23 at the bottom of the clamp plate 5 is triggered to open the air release valve, so that the air in the corresponding flip airbag 22 is released, and the reinforcement plate 21 loses the pressure of the flip airbag 22 and rotates to reset. The two reinforcement plates 21 that originally applied pressure symmetrically are left with only the reinforcement plate 21 on the other clamp plate 5 for unidirectional pressure testing, thereby pushing the stitching needle away, and the rotating clamp plate 5 plays a guiding role.

[0026] like Figure 3 As shown, a detection assembly for high voltage, short circuit and open circuit testing of the pin is arranged on the workbench 1, including a first detection frame 7 arranged above the clamping plate 5, and a first cylinder 6 for driving the first detection frame 7 to rise and fall is arranged above the screening table 2, wherein as shown Figure 3 As shown, a fixed frame 19 is provided on the workbench 1, a first cylinder 6 is installed on the fixed frame 19, a second detection frame 9 is provided on one side of the clamp plate 5, a second cylinder 8 for driving the second detection frame 9 to move horizontally is provided on the screening table 2, the second detection frame 9 is electrically connected to a high-voltage test machine 13, a mounting frame 3 is installed on the workbench 1, the high-voltage test machine 13 is placed on the mounting frame 3, a single-chip microcomputer is provided on one side of the high-voltage test machine 13, two second movable plates 12 are slidably installed on the outer wall of the second detection frame 9 close to the screening table 2, the two second movable plates 12 are movably installed with the first movable plates 11, the two first movable plates 11 are commonly connected with a probe 10, the probe 10 is provided with a truncated cone-shaped connecting groove, the probe 10 and the second detection frame 9 are electrically connected, a control switch for the first cylinder 6 and the second cylinder 8 is provided on the workbench 1, and a safety grating 27 is provided on the mounting frame 3.

[0027] The specific detection step is to start the first cylinder 6 after the stitching needle is clamped, and drive the first detection frame 7 to move downward. Figure 3As shown, two probes are arranged on the first detection frame 7, and the two probes are connected to the stitching needles. The two probes are externally connected to a power supply to detect whether the stitching needles are short-circuited or open-circuited. If either of the two occurs, it is considered as a defective product. At this time, the above-mentioned screening method is used to drive the clamping plate 5 close to the fixed frame 19 to rotate, so that the stitching needles are pushed into the screening holes 16. Figure 1-Figure 4 As shown, a screening plate 17 is rotatably installed in the screening hole 16, and the screening plate 17 divides the screening hole 16 into two parts, which are hereinafter referred to as the first part and the second part, and secondary screening is performed according to the type of unqualified detection. During the detection process of the first detection frame 7 mentioned above, the reversing plate 15 squeezes the screening plate 17 to rotate. When the first detection frame 7 fails the detection, the reversing plate 15 is squeezed and rotated, and the unqualified stitching needles are pushed into the first part. After the first detection frame 7 passes the detection, the first cylinder 6 drives it to move up and reset. At this time, the reversing plate 15 moves up and separates from the detection screening plate 17, and the screening plate 17 rotates and resets. Figure 4 As shown, a high voltage test is then performed, that is, the probe on the second detection frame 9 is used to connect and detect the stitching needle. The probe is only connected to one end of the stitching needle. It is worth noting that a conductive rod is provided on the mounting plate 4 (which can be elastically connected to adapt to stitching needles of different heights), and the conductive rod is externally connected to a current detection device (the device is a prior art, which detects whether there is current flowing through the conductive rod). The stitching needle is wrapped with an insulating layer on the outside, and the conductive parts are exposed at both ends. The conductive rod is connected to the insulating layer. When one end of the stitching needle is subjected to a high voltage, if it is broken down, the conductive rod will have current, so it is judged as a defective product, otherwise it is passed. For stitching needles that fail the high voltage test, the splint 5 close to the fixing frame 19 is rotated to push the stitching needle into the screening hole 16, but after the stitching needle enters the screening hole 16, it will enter the second part of the screening hole 16 under the guidance of the screening plate 17. A collection box is provided below the first part and the second part, so that the reasons for the failure of the stitching needle can be distinguished in the later stage.

[0028] When both tests are qualified, the clamping plate 5 away from the fixing frame 19 is turned over so that the stitching needles are pushed into the screening slot 18.

[0029] It is worth noting that the probe 10 and the second detection frame 9 are movably connected. Figure 5 As shown, the position of the probe 10 is changed by sliding the first movable plate 11 and the second movable plate 12, wherein the sliding direction of the first movable plate 11 is perpendicular to the sliding direction of the second movable plate 12, and a truncated cone-shaped connecting groove is provided on the probe 10. The position of the probe 10 can be changed by squeezing the truncated cone-shaped connecting groove with a stitching needle, so that the connection is more accurate, thereby improving the accuracy of detection.

[0030] like Figure 3As shown, a positioning plate 41 is provided on the second detection frame 9, so that when the first cylinder 6 drives the first detection frame 7 to move upward, the positioning plate 41 can press the mounting plate 4 to prevent it from rebounding, thereby ensuring the stability of the high-voltage test.

[0031] A safety grating 27 is provided on the mounting frame 3 to sound an alarm when detecting an outsider, thereby improving the safety of the detection.

[0032] like Figure 8-Figure 10 As shown, in order to facilitate loading and improve the efficiency of detection, an auxiliary loading component is added, including a conveyor belt 28 arranged on the workbench 1, a plurality of placement racks 29 are slidably installed on the conveyor belt 28, a primary push plate 30 is installed on the placement rack 29, and a secondary push plate 33 is provided on one side of the primary push plate 30, the auxiliary loading component also includes a plurality of slides 31 fixedly installed on the conveyor belt 28, the placement rack 29 is slidably installed on the slide 31, the bottom of the primary push plate 30 passes through the placement rack 29 and extends into the slide 31, a first air bag 32 is provided in the slide 31, a storage groove is opened on the primary push plate 30, a second air bag is provided in the storage groove, the first air bag 32 and the second air bag are connected, a third cylinder 34 is provided on one side of the conveyor belt 28, and A feeding plate is provided at the output end of the third cylinder 34, a gear 35 is fixedly sleeved on the rotating shaft of the conveyor belt 28, a guide plate 39 is provided on one side of the conveyor belt 28, a guide groove 40 is opened on the guide plate 39, a rack 38 matched with the gear 35 is slidably installed in the guide groove 40, a one-way plate 25 is rotatably installed in the guide groove 40, a first piston tube 36 is fixedly installed on the workbench 1, a first piston rod is movably inserted in the first piston tube 36, and the rack 38 is fixedly connected to the first piston rod, a second piston tube 37 is provided on the workbench 1, a second piston rod is movably inserted at the top of the second piston tube 37, a pressure plate is fixedly installed on the top of the second piston rod, the pressure plate is located below the transmission plate 14, and a return spring is provided in the second piston tube 37.

[0033] The specific automatic loading method is to place a plurality of stitching needles one by one on the placement rack 29 in advance. When the first detection rack 7 moves downward, the transmission plate 14 moves downward to squeeze the second piston rod downward. The second piston rod moves downward to squeeze the air in the second piston tube 37 into the first piston tube 36, so that the first piston rod extends, thereby driving the rack 38 to translate and generate transmission with the gear 35, so that the rotating shaft of the conveyor belt 28 rotates, driving the placement rack 29 to move, as shown in FIG. Fig.10 As shown, the guide groove 40 is in a parallelogram shape, the initial position of the rack 38 is located at the upper right corner, the transmission process occurs from the upper right corner to the upper left corner, and then the rack 38 moves down along the inclined groove, and the one-way plate 25 is rotatably installed in the guide groove 40, and encounters Fig.10Taking the one-way plate 25 in the lower left corner as an example, the one-way plate 25 is initially horizontal and rotates downward under compression. The one-way plate 25 here cannot rotate upward when it is in a horizontal state. At this time, the rack 38 moves down to the horizontal groove below, and then when the first detection frame 7 is reset and moved up, the air pressure is restored, and the rack 38 is reset horizontally. At this time, the rack 38 will not transmit with the gear 35 due to the downward movement, and then moves up along the inclined groove. Similarly, the one-way plate 25 in the upper right corner can rotate upward and can be reset to a horizontal state, but it cannot rotate down in a horizontal state. This is a cycle, realizing the unidirectional periodic rotation of the conveyor belt 28 and completing intermittent feeding.

[0034] The stitches on the placement rack 29 are transferred to the two clamping plates 5 by the third cylinder 34. Fig. 9 As shown, the first push plate 30 is pushed, and the first push plate 30 and the placement rack 29 slide together toward the clamping plate 5. During the sliding process, the first airbag 32 is squeezed, and the air in the first airbag 32 enters the second airbag, thereby pushing the second push plate 33 to push the stitching needle, so that the stitching needle is separated from the placement rack 29 and moved between the two clamping plates 5. Automatic loading is realized. The efficiency and safety of detection are improved.

[0035] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein.
