Specific embodiments

[0032] In order to make the purposes, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0033] The present invention will be further described below with reference to the embodiments.

[0034] Embodiment: Refer to Figures 1-7, a semi-automatic performance detection device for needle splicing and encapsulation products, including a workbench 1, and further including a clamping assembly for clamping the needle splicing, which includes a screening table 2 installed on the workbench 1. An installation plate 4 is elastically installed on the screening table 2. Two clamping plates 5 are rotatably installed on the installation plate 4. Needle splicing is placed on the clamping plates 5. Reinforcing plates 21 are rotatably installed on both clamping plates 5. Arc-shaped grooves are provided on the outer walls of the two clamping plates 5 close to each other. A bracket is fixedly installed on the installation plate 4. The clamping plates 5 are rotatably installed on the bracket. The bottom of the clamping plate 5 is provided with an inclined surface, and an adjusting plate 24 is slidably installed on the inclined surface. One end of the adjusting plate 24 away from the clamping plate 5 is rotatably connected to a sliding plate 26. The sliding plate 26 is slidably connected to the top wall of the installation plate 4. The installation plate 4 is provided with an electric push rod for driving the sliding of the sliding plate 26. When the installation plate 4 slides towards the arc-shaped groove, the clamping plate 5 connected thereto rotates towards the installation plate 4. A screening groove 18 is provided on the outer wall of one side of the screening table 2, and screening holes 16 are provided on the top wall of the screening table 2. A screening plate 17 is rotatably installed in the screening holes 16, and a coil spring is provided at the rotation connection of the screening plate 17. A transmission plate 14 is fixedly installed on one side of the first detection frame 7, and a reversing plate 15 is fixedly installed on the bottom wall of the transmission plate 14. When the reversing plate 15 moves downward, it squeezes the screening plate 17 to rotate. An elastic rod is connected between the bottom wall of the installation plate 4 and the screening table 2. An auxiliary airbag 20 is fixedly installed on the bottom wall of the installation plate 4. Reinforcing grooves are provided on the top wall of the clamping plate 5, and the reinforcing plates 21 are rotatably installed in the reinforcing grooves. A reversing airbag 22 is fixedly installed in the reinforcing grooves. The reversing airbags 22 on the same clamping plate 5 are jointly connected to a shunt pipe 23, and the shunt pipe 23 is communicated with the auxiliary airbag 20. A deflation valve is provided on the shunt pipe 23, and a pressure switch is provided on the deflation valve. When the adjusting plate 24 slides towards the shunt pipe 23, it squeezes the pressure switch to open the deflation valve.

[0035] To ensure the accuracy of the detection, a clamping assembly is installed on the workbench 1, as Figure 6 shown, the needle splicing is clamped between the two clamping plates 5. Arc-shaped grooves are provided on the side walls of the clamping plates 5, which can adapt to the external contour of the needle splicing to a certain extent. Of course, modifying the contour of the groove according to the actual contour of the needle splicing does not affect the clamping result.

[0036] As Figure 3 shown, when the first detection frame 7 moves downward to detect the needle splicing, it will squeeze the installation plate 4 to move downward, and then the second detection frame 9 moves horizontally and gradually approaches the needle splicing. When the installation plate 4 moves downward, the auxiliary airbag 20 is squeezed and contracted, and the air in the auxiliary airbag 20 enters the reversing airbag 22 through the shunt pipe 23. The reversing airbag 22 expands and squeezes the reinforcing plate 21 to rotate. The number of reinforcing plates 21 on the two clamping plates 5 is the same and their positions are symmetrical, so as to improve the stability of the detection.

[0037] 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, and a one-way valve is also provided.

[0038] As Figure 6 and Figure 7 shown, a reinforcing plate 21 is provided on the clamping plate 5, and a coil spring is provided at the rotating connection of the reinforcing plate 21 to help it reset.

[0039] The above-mentioned clamping plate 5 is installed on the mounting plate 4 in a rotating manner. In this way, the clamping plate 5 not only has a clamping function, but also has the ability to guide after rotating and tilting. Specifically, as Figure 7 shown, two electric push rods (not shown in the figure) are respectively used to drive two sliding plates 26 to slide on the mounting plate 4. The adjusting plate 24 is rotatably connected above the sliding plate 26, and the adjusting plate 24 slides along the inclined surface at the bottom of the corresponding clamping plate 5. When the sliding plate 26 slides towards the knitting needle direction, the clamping plate 5 deflects, and during the sliding process of the sliding plate 26, a pressure switch on the flow dividing pipe 23 at the bottom of the clamping plate 5 is triggered to open the air release valve, so that the air in the corresponding flipping airbag 22 is released. The reinforcing plate 21 loses the pressure of the flipping airbag 22 and rotates to reset. Only the reinforcing plate 21 on the other clamping plate 5 that applies pressure unidirectionally remains from the two originally symmetrically applying pressure reinforcing plates 21, so as to push away the knitting needle, and the rotating clamping plate 5 plays a guiding role.

[0040] As Figure 3 shown, a detection assembly for high voltage, short circuit and open circuit tests of knitting needles is provided on the workbench 1, including a first detection frame 7 provided above the clamping plate 5, and a first air cylinder 6 for driving the first detection frame 7 to lift is provided above the screening table 2. Among them, as Figure 3 shown, a fixing frame 19 is provided on the workbench 1, the first air cylinder 6 is installed on the fixing frame 19, a second detection frame 9 is provided on one side of the clamping plate 5, and a second air 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 tester 13. An installation frame 3 is installed on the workbench 1, the high voltage tester 13 is placed on the installation frame 3, a single-chip microcomputer is provided on one side of the high voltage tester 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, a first movable plate 11 is movably installed on each of the two second movable plates 12, the two first movable plates 11 are commonly connected to a probe 10, a frustum-shaped connection groove is provided in the probe 10, and the probe 10 is electrically connected to the second detection frame 9. A control switch for the first air cylinder 6 and the second air cylinder 8 is provided on the workbench 1, and a safety light curtain 27 is provided on the installation frame 3.

[0041] The specific detection steps are as follows: After clamping the knitting needle, start the first air cylinder 6 to drive the first detection frame 7 to move downward. As Figure 3As shown in the figure, two probes are arranged on the first detection rack 7. The two probes are connected to the spliced pins, and the two probes are externally connected to a power supply to detect whether the spliced pins are short-circuited or open-circuited. If either of them occurs, it is regarded as a defective product. At this time, use the above screening method to drive the clamping plate 5 close to the fixed rack 19 to rotate, so that the spliced pins are pushed into the screening holes 16. As Figures 1-4 shown, a screening plate 17 is rotatably installed in the screening holes 16. The screening plate 17 divides the screening holes 16 into two parts, which are subsequently referred to as the first part and the second part, and secondary screening is carried out according to the types of unqualified detections. During the detection process of the above-mentioned first detection rack 7, the reversing plate 15 will squeeze the screening plate 17 to rotate. When the first detection rack 7 detects unqualified, at this time the reversing plate 15 is squeezed to rotate, and the unqualified spliced pins are pushed into the first part. After the first detection rack 7 detects qualified, the first cylinder 6 will drive 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, as Figure 4 shown, then a high-voltage test is carried out, that is, the probe on the second detection rack 9 is connected to the spliced pin for detection. The probe is only connected to one end of the spliced pin. It should be noted that a conductive rod (which can be elastically connected to adapt to spliced pins of different heights) is arranged on the mounting plate 4, and the conductive rod is externally connected to a current detection device (this device is a prior art to detect whether there is current flowing through the conductive rod). The outside of the spliced pin is wrapped with an insulating layer, and the two ends thereof expose the conductive parts. The conductive rod is connected to the insulating layer. When a high voltage is applied to one end of the spliced pin, if it is broken down, there will be current in the conductive rod, so it is judged as a defective product, otherwise it passes. For the spliced pins that fail the high-voltage test, by rotating the clamping plate 5 close to the fixed rack 19, the spliced pins are pushed into the screening holes 16, but after the spliced pins enter the screening holes 16, they will enter the second part of the screening holes 16 under the guiding action of the screening plate 17. A collection box is arranged below both the first part and the second part, so that the reasons for the unqualified spliced pins can be distinguished later.

[0042] When both detections are qualified, flip the clamping plate 5 away from the fixed rack 19 so that the spliced pins are pushed into the screening groove 18.

[0043] It should be noted that the probe 10 and the second detection rack 9 are movably connected. As Figure 5 shown, by the sliding installation of the first movable plate 11 and the second movable plate 12, the position of the probe 10 is changed. Among them, the sliding directions of the first movable plate 11 and the second movable plate 12 are perpendicular to each other, and a frustum-shaped connecting groove is arranged on the probe 10. The spliced pin squeezing the frustum-shaped connecting groove can change the position of the probe 10, making the connection more accurate and improving the detection accuracy.

[0044] As Figure 3As shown in the figure, a positioning plate 41 is provided on the second detection rack 9. This is to ensure that when the first cylinder 6 drives the first detection rack 7 to move upward and away, the positioning plate 41 can press the mounting plate 4 to prevent it from rebounding and ensure the stability of the high-pressure test.

[0045] A safety light curtain 27 is provided on the mounting rack 3 to give an alarm when detecting external personnel and improve the safety of detection.

[0046] As Figures 8-10 shown in the figure, in order to facilitate feeding and improve the detection efficiency, an auxiliary feeding component is also added, including a conveyor belt 28 provided on the workbench 1. A plurality of placement racks 29 are slidably mounted on the conveyor belt 28. A primary push plate 30 is mounted on the placement rack 29. A secondary push plate 33 is provided on one side of the primary push plate 30. The auxiliary feeding component further includes a plurality of sliding racks 31 fixedly mounted on the conveyor belt 28. The placement rack 29 is slidably mounted on the sliding rack 31. The bottom of the primary push plate 30 penetrates through the placement rack 29 and extends into the sliding rack 31. A first airbag 32 is provided in the sliding rack 31. A storage groove is formed in the primary push plate 30, and a second airbag is provided in the storage groove. The first airbag 32 and the second airbag are communicated with each other. 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 formed in the guide plate 39. A rack 38 adapted to the gear 35 is slidably mounted in the guide groove 40. A one-way plate 25 is rotatably mounted in the guide groove 40. A first piston tube 36 is fixedly mounted on the workbench 1. A first piston rod is movably inserted into 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 into the top end of the second piston tube 37, and a pressing plate is fixedly mounted at the top end of the second piston rod. The pressing plate is located below the transmission plate 14, and a return spring is provided in the second piston tube 37.

[0047] The specific automatic feeding method is as follows: A plurality of pin connectors are placed on the placement rack 29 one by one 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, causing the first piston rod to extend, thereby driving the rack 38 to translate and engage with the gear 35, so that the rotating shaft of the conveyor belt 28 rotates, driving the placement rack 29 to move. As Figure 10 shown in the figure, the guide groove 40 is in the shape of a parallelogram. The initial position of the rack 38 is 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 downward along the inclined groove. A one-way plate 25 is rotatably mounted in the guide groove 40. When encountering Figure 10Taking the one-way plate 25 in the lower left corner as an example, the one-way plate 25 is in a horizontal state initially. When it is squeezed, it rotates downward. The one-way plate 25 here cannot rotate upward when it is in a horizontal state. At this time, the rack 38 moves downward into the lower horizontal groove. Then when the first detection frame 7 resets and moves upward, the air pressure recovers. The rack 38 translates and resets. At this time, since the rack 38 moves downward, it will not drive with the gear 35, and then it moves upward along the inclined groove. Similarly, the one-way plate 25 in the upper right corner can rotate upward and can reset to a horizontal state, but it cannot rotate downward in a horizontal state. Thus, a cycle is completed, realizing the one-way periodic rotation of the conveyor belt 28 and completing the intermittent feeding.

[0048] The third air cylinder 34 is used to transfer the assembling needles on the placing rack 29 to the two clamping plates 5. As Figure 9 shown, the first-level push plate 30 is pushed. The first-level push plate 30 and the placing rack 29 slide together in the direction of the clamping plates 5. During the sliding process, the first airbag 32 is squeezed. The air in the first airbag 32 enters the second airbag, thereby pushing the second-level push plate 33 to push the assembling needles, so that the assembling needles are separated from the placing rack 29 and move between the two clamping plates 5. Automatic feeding is realized. The detection efficiency and detection safety are improved.

[0049] 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 foregoing embodiments, those of ordinary skill in the art should understand that: they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements for some of the technical features; and these modifications or replacements will not make the essence of the corresponding technical solutions deviate from the protection scope of the technical solutions of the embodiments of the present invention.
