DETAILED DESCRIPTION

[0023] The utility model is further described in detail below in conjunction with the accompanying drawings.

[0024] Example:

[0025] Reference Figures 1 to 3The utility model discloses a high-precision ballpoint pen detection device, comprising a workbench, which is composed of a base 2 and a side frame 1 fixedly connected to the top of the base 2. Two side panels 3 are fixedly connected to one side of the side frame 1, and a limiting tube 4 with openings at both ends is arranged above the base 2, and the limiting tube 4 is fixedly passed through the two side panels 3. A fixing portion 5 is arranged on the outer peripheral side of the limiting tube 4.

[0026] A fixing plate 6 is fixedly connected to the top of the base 2, two first electric push rods 7 are fixedly connected to one side of the fixing plate 6, and an impact plate 8 is fixedly connected to the output ends of the two first electric push rods 7. A bearing portion 9 is arranged inside the impact plate 8. A collection box 10 with an opening on the top is placed on the lower half of one side of the base 2.

[0027] In this embodiment, when the ballpoint pen is tested, the ballpoint pen is inserted into the limiting tube 4 from the top of the limiting tube 4. The inner diameter of the limiting tube 4 is slightly larger than the diameter of the ballpoint pen, and the inner diameter of the limiting tube 4 is relatively smooth. The distance between the bottom end of the limiting tube 4 and the top surface of the impact plate 8 is smaller than the length of the ballpoint pen, and the distance between the bottom end of the limiting tube 4 and the top surface of the base 2 is larger than the length of the ballpoint pen.

[0028] In a further preferred embodiment of the present invention, Figure 1 As shown, one end of the impact plate 8 away from the first electric push rod 7 is fixedly connected to a push plate 11 .

[0029] In this embodiment, the movement of the impact plate 8 drives the push plate 11 to move. The length of the push plate 11 is the same as the length of the base 2. Therefore, when the push plate 11 moves, it can ensure that the ballpoint pen that falls on the top surface of the base 2 is pushed into the collection box 10.

[0030] In a further preferred embodiment of the present invention, Figure 2 As shown, the fixing part 5 includes two upper plates 51 slidably penetrated on the upper half of the position limiting tube 4, and the two upper plates 51 are fitted. Two lower plates 52 are slidably penetrated on the lower half of the position limiting tube 4. A linkage plate 53 is fixedly connected to the upper plate 51 and the corresponding lower plate 52 on the side away from the position limiting tube 4, and two second electric push rods 54 are fixedly connected between the linkage plate 53 and the outer peripheral surface of the position limiting tube 4.

[0031] In this embodiment, in the initial state, the two upper plates 51 are in contact with each other, and the lower plate 52 slightly extends into the limiting tube 4 .

[0032] When the ballpoint pen is placed, it falls on the two upper plates 51, so the initial height of the ballpoint pen is the same each time the ballpoint pen is dropped. The second electric push rod 54 works to drive the linkage plate 53 to move away from the limit tube 4, and the two upper plates 51 move in the opposite direction. The ballpoint pen falls under the action of gravity and hits the top of the impact plate 8, and the pen tip hits the impact plate 8.

[0033] In a further preferred embodiment of the present invention, Figure 3 As shown, the bearing portion 9 includes a top groove 91 opened at the top of the impact plate 8, two fixed rollers 92 are fixedly connected to the upper half of the top groove 91, and two collecting rollers 93 are rotatably sleeved on the lower half of the top groove 91.

[0034] A writing paper 94 is fixedly connected to the outer circumference of one of the collecting rollers 93, and a portion of the writing paper 94 is wound around the outer circumference of the collecting roller 93, and the other end of the writing paper 94 is fixedly connected to the outer circumference of the other collecting roller 93. The writing paper 94 is in contact with the outer walls of both fixed rollers 92, and the top surface of the writing paper 94 between the two fixed rollers 92 is coplanar with the top surface of the impact plate 8. A driving unit 95 is provided in the top groove 91.

[0035] In this embodiment, when the ballpoint pen hits the top of the impact plate 8, the first electric push rod 7 works to drive the impact plate 8 to move horizontally, so that the writing paper 94 moves toward the ballpoint pen. Therefore, when the writing paper 94 passes over the ballpoint pen, the ballpoint pen leaves writing marks on the writing paper 94. The operator judges the anti-drop performance of the ballpoint pen by observing the writing marks.

[0036] In a further preferred embodiment of the present invention, Figure 3 As shown, the driving part 95 includes a motor fixedly connected to the inner wall of the top groove 91, the output end of the motor is transmission-connected with a driving gear, and a driven gear is fixedly sleeved on the outer circumference of the corresponding collecting roller 93, and the driving gear is meshed with the driven gear.

[0037] In this embodiment, the motor drives the driving gear to rotate, the driving gear drives the driven gear to rotate, the driven gear drives the corresponding collecting roller 93 to rotate, thereby driving the writing paper 94 to move and collect the written part into the top groove 91.

[0038] In a further preferred embodiment of the present invention, Figure 1 As shown, the bottom surface of the impact plate 8 is in contact with the top surface of the base 2 .

[0039] In this embodiment, the base 2 supports the impact plate 8 to prevent the impact plate 8 from tilting.

[0040] In a further preferred embodiment of the present invention, Figure 2 As shown, the side wall of the upper plate 51 located inside the limiting tube 4 is provided with avoidance openings 12 , and the tip of the ballpoint pen passes through the two avoidance openings 12 .

[0041] In this embodiment, when preventing the ballpoint pen from falling, the tip of the ballpoint pen passes through the avoidance opening 12, ensuring that the tip of the pen is not impacted before contacting the impact plate 8, thereby improving the accuracy of the ballpoint pen anti-drop test.

[0042] The implementation principle of the above embodiment is:

[0043] First, insert the ballpoint pen into the limiting tube 4 from the top, and the ballpoint pen falls to the two upper plates 51. Start the two electric push rods to drive the linkage plate 53 to move away from the limiting tube 4, and the two upper plates 51 move in the opposite direction. The ballpoint pen falls and hits the top of the impact plate 8 under the action of gravity, and the pen tip hits the impact plate 8.

[0044] Then the first electric push rod 7 works, driving the impact plate 8 to move, and the impact plate 8 drives the writing paper 94 to move toward the ballpoint pen until the pen tip contacts the top surface of the writing paper 94, and the second electric push rod 54 works in the reverse direction, driving the two lower plates 52 to move in the reverse direction to the original position, fixing the ballpoint pen. The first electric push rod 7 continues to work, driving the writing paper 94 to move relative to the ballpoint pen, and the ballpoint pen leaves writing marks on the writing paper 94. The operator judges the anti-drop performance of the ballpoint pen by observing the writing marks.

[0045] Until the impact plate 8 completely passes over the ballpoint pen, the second electric push rod 54 works, driving the two lower plates 52 to move in the opposite direction, and the ballpoint pen continues to fall and lands on the top surface of the base 2. The first electric push rod 7 works in the opposite direction, driving the push plate 11 to push the ballpoint pen to move and push the ballpoint pen into the collection box 10. After that, the first electric push rod 7 returns to its initial position, and the second electric push rod 54 also returns to its initial position, waiting for the next ballpoint pen to be detected.

[0046] After the impact plate 8 completely passes over the ballpoint pen, the motor starts to drive the writing paper 94 to move, and the written part is received into the top groove 91.

[0047] The first electric push rod 7, the second electric push rod 54 and the motor are controlled by a PLC controller.

[0048] The embodiments of this specific implementation method are all preferred embodiments of the utility model, and are not intended to limit the protection scope of the utility model. Therefore, all equivalent changes made based on the structure, shape, and principle of the utility model should be included in the protection scope of the utility model.
