[0012] Compared with the prior art, the present invention provides a detection device for plastic part production, which has the following beneficial effects:

[0013] For the detection device used in plastic part production, kits such as buzzers that need to be powered on for detection are placed in each fixed tube. Then, the moving bar is moved between the two pushing bars, and then the two pushing bars are moved towards each other. Due to the mutual cooperation of the four through slots and the four connecting columns, when the two pushing bars move towards each other, they will move in opposite left and right directions. Combining with the protrusions on the pushing bars, the pins socketed with each buzzer, etc. will be toggled. When the two pushing bars are in contact, the positions of each pin will be positioned.

[0015] For the detection device used in plastic part production, through the elastic force of each compression spring a, after the detection is completed, the extrusion bar can be moved upward, and thus the rebound of the compression spring a will drive the sliding frame to move forward, so that the user can quickly remove the detected buzzers, etc.

[0016] For the detection device used in plastic part production, when each trapezoidal block moves backward under extrusion, it will respectively squeeze each compression spring b, so that the compression spring b can apply pressure to the sliding frame, so as to avoid damage to the sockets of buzzers, etc. caused by rigid extrusion.

[0017] For the detection device used in plastic part production, the trapezoidal block can be limited by the limit block and the small groove, so as to avoid the trapezoidal block moving forward too far due to the rebound of the compression spring b, resulting in the upper straight surface being exposed to block the downward movement of the extrusion bar. The position of the moving plate to the left can be limited by the telescopic bar, and at the same time, the position of the moving plate can be positioned.

[0018] For the detection device used in plastic part production, the arc-shaped handle can facilitate the user to move the extrusion bar up and down. When the extrusion bar is moved upward to a suitable position, the hemispherical block will be squeezed into the round groove. When the two hemispherical grooves are aligned with the two hemispherical blocks, the rebound of the compression spring c will make the two hemispherical blocks enter the two hemispherical grooves, so that the extrusion bar can be fixed by the extrusion force.

[0019] 7. For the detection device used in the production of this plastic part, after moving the moving plate under the inclined box and then sleeving the two semi - rings on the two guiding rods respectively, and then moving the moving plate upward, each blanking slot can be made to correspond to each fixed tube respectively.

Then, by restoring the lifting bar, the blocking bar can block the items that continue to slide down. In this way, it is convenient for users to quickly place the sockets such as the buzzer in each fixed tube. BRIEF DESCRIPTION OF THE DRAWINGS

A fixed tube 31 is fixedly installed in each groove 32. A support plate 4 is fixedly installed on the workbench 1. Two support bars 5 are fixedly installed on the front of the support plate 4. Two inclined bars 6 are fixedly installed at the front ends of the two support bars 5. Through slots 24 are formed on the four inclined bars 6. A connecting column 22 is movably connected in each through slot 24. A support ring 23 is fixedly installed on each connecting column 22. The lower side of each support ring 23 is respectively in contact with the upper side of each inclined bar 6. Two push bars 7 are arranged below the four inclined bars 6. The upper sides of the two push bars 7 are respectively fixedly connected to the four connecting columns 22. A row of protrusions are arranged on the sides of the two push bars 7 close to each other. By placing components such as buzzers that need to be powered on for detection in each fixed tube 31, then moving the moving bar 30 between the two push bars 7, and then moving the two push bars 7 in the direction of approaching each other. Due to the mutual cooperation of the four through slots 24 and the four connecting columns 22, when the two push bars 7 approach each other, they will move in opposite left and right directions. Combining with the protrusions on the push bars 7, the pins sleeved on each buzzer etc. will be toggled. When the two push bars 7 are in contact, the positions of each pin will be positioned. Then move the lifting plate 3 downward so that the electrical connection ports on its lower side are in contact with the pins to supply power. In this way, it is possible to simultaneously detect whether a plurality of buzzers etc. sleeved can be used normally. An arc-shaped plate 41 movably penetrates through each fixed tube 31. An extrusion groove 33 is formed on the upper side of the moving plate 30. A plurality of sliding grooves 51 are formed on the rear inner wall of the extrusion groove 33. A sliding frame 43 is movably connected in each sliding groove 51. A trapezoidal block 46 is arranged on the front of each sliding frame 43. Each trapezoidal block 46 is respectively slidably connected to each sliding groove 51. A support frame 25 is fixedly installed on the upper side of the moving plate 30. An extrusion bar 27 is movably connected in the support frame 25. The extrusion bar 27 is arranged directly above the extrusion groove 33. After the pins are positioned by the two push bars 7, pressing the extrusion bar 27 downward can squeeze the inclined surfaces of each trapezoidal block 46 through the extrusion bar 27, so that each trapezoidal block 46 can move backward. In this way, each sliding frame 43 can be driven to move backward, and then each buzzer etc. sleeved can be fixed by the backward moving arc-shaped plates 41 to prevent rotation. A small plate 52 is arranged in each sliding frame 43. A small rod 42 movably penetrates through each small plate 52. A compression spring a50 is movably sleeved on each small rod 42. The front and rear ends of each compression spring a50 are respectively fixedly connected to the front of each small plate 52 and the front inner wall of each sliding frame 43. Through the elastic force of each compression spring a50, after the detection is completed, the extrusion bar 37 can be moved upward, and then the rebound of the compression spring a50 will drive the sliding frame 43 to move forward.In this way, the user can quickly remove the socketed buzzer and the like after the detection is completed. A pressure spring b44 is fixedly installed on the front surface of each sliding frame 43. A limiting rod 45 is movably connected inside each pressure spring b44. Each limiting rod 45 is fixedly connected to the front surface of each sliding frame 43 respectively. A limiting groove 47 is formed on the rear side of each trapezoidal block 46. Each limiting rod 45 is movably connected to each limiting groove 47 respectively. The rear side of each trapezoidal block 46 is fixedly connected to the front end of each pressure spring b44 respectively. When each trapezoidal block 46 is squeezed and moves backward, it will squeeze each pressure spring b44 respectively, so that the pressure spring b44 can apply pressure to the sliding frame 43, thus avoiding damage to the socket of the buzzer and the like caused by rigid extrusion. A limiting block 48 is fixedly installed on the lower side of each trapezoidal block 46. A small groove 49 is formed on the lower inner wall of each chute 51. Each limiting block 48 is movably connected to each small groove 49 respectively. Guide bars 12 are fixedly installed on the right side of both limiting bars 11. A notch 8 is formed on the front limiting bar 11 of the two limiting bars 11. A telescopic bar 9 is movably connected in the notch 8. A small block 10 is arranged in front of the telescopic bar 9. The small block 10 is fixedly installed on the workbench 1. Through the limiting block 48 and the small groove 49, the trapezoidal block 46 can be limited, thus avoiding the trapezoidal block 46 moving forward too far due to the rebound of the pressure spring b44 and causing the upper straight surface to be exposed to block the downward movement of the extrusion bar 27. The telescopic bar 9 can limit the position of the moving plate 30 to the left and can also position the moving plate 30 at the same time. Two square blocks 26 are fixedly installed on the upper side of the support frame 25. Circular grooves 35 are formed on the sides of the two square blocks 26 close to each other. A moving column 40 is movably connected in each circular groove 35. Hemispherical blocks 38 are fixedly installed at the ends of the two moving columns 40 close to each other. Hemispherical grooves 37 are formed on the left and right sides of the extrusion bar 27. Pressure springs c34 are fixedly installed at the ends of the two moving columns 40 away from each other. Each pressure spring c34 is fixedly connected to the inner side wall of the two circular grooves 35 away from each other respectively. Annular wall grooves 39 are formed on the inner side walls of the two circular grooves 35. A snap ring 36 is movably connected in each annular wall groove 39. The two snap rings 36 are fixedly sleeved on the two moving columns 40 respectively. An arc-shaped handle 28 is fixedly installed on the upper side of the extrusion bar 27. Through the arc-shaped handle 28, the user can conveniently move the extrusion bar 27 up and down. When the extrusion bar 27 moves up to a proper position, the hemispherical block 38 will be squeezed into the circular groove 35. When the two hemispherical grooves 37 are aligned with the two hemispherical blocks 38, the rebound of the pressure spring c34 will cause the two hemispherical blocks 38 to enter the two hemispherical grooves 37, so that the extrusion bar 27 can be fixed by the squeezing force. Two vertical bars 13 are fixedly installed on the upper side of the workbench 1. An inclined box 17 is fixedly installed on the two vertical bars 13. A plurality of blanking grooves 21 are formed on the lower wall of the inclined box 17. Two guide rods 14 are fixedly installed on the lower side of the inclined box 17. Two semi-rings 29 are fixedly installed on the rear side of the moving plate 30. A plurality of guide blocks 16 are fixedly installed on the lower inner wall of the inclined box 17.On both the left and right sides of the inclined box 17, square plates 15 are fixedly installed. On the sides of the two square plates 15 that are close to each other, inclined slots 20 are provided. A lifting bar 18 is movably connected in the two inclined slots 20. A number of groups of blocking bars 19 are fixedly installed on the lower side of the lifting bar 18. After moving the moving plate 30 below the inclined box 17, putting the two semi-rings 29 on the two guide rods 14 respectively, and then moving the moving plate 30 upward, each blanking slot 21 can correspond to each fixed tube 31 respectively. In this way, the lifting bar 18 can be moved upward, so that each blocking bar 19 can be moved upward. In this way, the sockets such as buzzers in the inclined box 17 will slide into each fixed tube 31. Then, by restoring the lifting bar 18 to make the blocking bar 19 block the items that continue to slide down, it is convenient for users to quickly place the sockets such as buzzers in each fixed tube 31.,

[0033] During use, the first step: Place the kits such as buzzers that need to be powered on and detected in each fixed tube 31. Then move the moving bar 30 between the two pushing bars 7. Then move the two pushing bars 7 in the direction of approaching each other. Due to the mutual cooperation of the four through slots 24 and the four connecting columns 22, when the two pushing bars 7 approach each other, they will move in opposite left and right directions. Coupled with the protrusions on the pushing bars 7, the pins of each socket such as a buzzer will be toggled. When the two pushing bars 7 are in contact, the positions of each pin will be positioned. Then move the lifting plate 3 downward so that the electrical connection ports on its lower side contact the pins to supply power. In this way, it is possible to simultaneously detect whether a number of sockets such as buzzers can be used normally.,

[0034] The second step: After positioning the pins through the two pushing bars 7, pressing the extrusion bar 27 downward can squeeze the inclined surfaces of each trapezoidal block 46 through the extrusion bar 27, so that each trapezoidal block 46 can move backward. In this way, each sliding frame 43 can be driven to move backward, so that each socket such as a buzzer can be fixed by the backward moving arc-shaped plates 41 to prevent rotation.,

[0035] The third step: Through the elastic force of each compression spring a50, after the detection is completed, the extrusion bar 37 can be moved upward. Thus, the rebound of the compression spring a50 will drive the sliding frame 43 to move forward, so that users can quickly remove the detected sockets such as buzzers.,

[0036] The fourth step: When each trapezoidal block 46 is squeezed and moves backward, it will respectively squeeze each compression spring b44. Thus, the compression spring b44 can apply pressure to the sliding frame 43, so as to avoid damage to the sockets such as buzzers caused by rigid extrusion.,

[0037] Step 5: The trapezoidal block 46 can be limited by the limiting block 48 and the small groove 49, so as to avoid the trapezoidal block 46 moving forward too far due to the rebound of the compression spring b44, resulting in the straight surface on the upper side being exposed to block the downward movement of the extrusion bar 27. The telescopic bar 9 can limit the position of the moving plate 30 to the left and can also position the moving plate 30.

[0038] Step 6: The arc handle 28 can facilitate the user to move the extrusion bar 27 up and down. When the extrusion bar 27 moves up to a suitable position, the hemispherical block 38 will be squeezed into the circular groove 35. When the two hemispherical grooves 37 are aligned with the two hemispherical blocks 38, the rebound of the compression spring c34 will cause the two hemispherical blocks 38 to enter the two hemispherical grooves 37, so that the extrusion bar 27 can be fixed by the extrusion force.

[0039] Step 7: After moving the moving plate 30 below the inclined box 17, putting the two half-rings 29 on the two guide rods 14 respectively, and then moving the moving plate 30 upward, each blanking groove 21 can be made to correspond to each fixed tube 31 respectively. In this way, the lifting bar 18 can be moved upward, so that each blocking bar 19 can move upward. Then the sockets such as the buzzer in the inclined box 17 will slide into each fixed tube 31. Then, by restoring the lifting bar 18, the blocking bar 19 can block the items that continue to slide down, which can facilitate the user to quickly place the sockets such as the buzzer in each fixed tube 31.
