[0032] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are one embodiment of the present invention, rather than all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present invention.

[0033] Please refer to Figures 1 to 11 , the present invention provides a carbon crystal detection device.

[0034] As [[ID=2)5]] Figure 2 shown, the carbon crystal detection device mainly detects whether the combination of the carbon crystal and the rubber cover is smooth and whether the frictional force generated by the horizontal movement exceeds the target standard; it can also detect whether the carbon crystal is installed and whether there is a situation of missing installation.

[0035] As Figure 2As shown, in this embodiment, the carbon crystal detection device includes two parts. One part is the handling component 3, and the other part is the detection part. Both the handling component 3 and the detection part are installed on the first mounting plate 1.

[0036] The first implementation manner of the detection part: directly collect and detect the frictional force. The beneficial effects are: simple structure and fast direct detection speed. However, the disadvantages are: relatively large detection error.

[0037] As Figure 3 shown, a placement tray 2 is installed on the first mounting plate 1. A rubber cover 11 and carbon crystals 12 installed on both sides of the rubber cover 11 are placed on the placement tray 2. Two carbon crystals 12 need to be detected simultaneously, so detection components 4 are installed on both sides of the placement tray 2. In this way, the detection components 4 can detect the carbon crystals 12 directly opposite. Further, the detection components 4 are installed at the end of a lateral driving component 5, and the lateral driving component 5 is installed on the first mounting plate 1. The detection components 4 include force sensors 41 provided at the end. The detection components 4 mainly collect and detect the frictional force through the force sensors 41 provided at the end.

[0038] Specifically, the lateral driving component 5 drives the detection components 4 to move laterally. The force sensors 41 contact the carbon crystals 12 and push the carbon crystals 12 to move laterally inside the rubber cover 11, and detect the frictional force generated by the lateral movement of the carbon crystals 12 inside the rubber cover 11. The magnitude of the frictional force is collected, and further, it is judged whether the lateral movement of the carbon crystals 12 inside the rubber cover 11 is smooth or not, and whether the frictional force exceeds the target standard.

[0039] In this embodiment, a longitudinal driving component 6 is installed below the placement tray 2. The longitudinal driving component 6 is installed on the first mounting plate 1. The longitudinal driving component 6 drives the placement tray 2 to move longitudinally back and forth to move away from or close to the detection components 4.

[0040] If the rubber cover 11 and the carbon crystals 12 are placed manually, they can be moved away from the placement position for detection to protect the safety of the placer. If it is automatic placement in this embodiment, it is coordinated with the handling component 3 to realize automatic cyclic feeding.

[0041] As Figure 4As shown, the longitudinal drive assembly 6 includes a first longitudinal cylinder 61 installed at one end of the first mounting plate 1, a longitudinal slider 62 installed at the end of the first longitudinal cylinder 61, and a longitudinal guide rail 63 installed between the first mounting plate 1 and the longitudinal slider 62. To precisely control the longitudinal movement, in this embodiment, the longitudinal guide rail 63 is fixedly installed on the first mounting plate 1. The first longitudinal cylinder 61 drives the longitudinal slider 62 to reciprocate longitudinally along the longitudinal guide rail 63. Further, a placement tray 2 is installed on the longitudinal slider 62. The longitudinal slider 62 and the longitudinal guide rail 63 cooperate with each other to achieve precise longitudinal movement of the rubber cover 11 and the carbon crystal 12, realizing automatic longitudinal loading and unloading.

[0042] As Figure 4 shown, to stably place the rubber cover 11 on the placement tray 2, the placement tray 2 is provided with a placement groove 21, and the placement groove 21 is adapted to the bottom of the rubber cover 11; further, to position the rubber cover 11, a second positioning post 22 is installed on one side of the placement groove 21, and the second positioning post 22 is inserted into the positioning groove 18 of the rubber cover 11 to achieve insertion positioning of the rubber cover 11.

[0043] Furthermore, a vertical return spring is installed between the inside of the second positioning post 22 and the placement tray 2. When the rubber cover 11 needs to be taken out, the first pressing rod 37 presses vertically downward, pressing the second positioning post 22 and compressing the vertical return spring to disengage the second positioning post 22 from the positioning groove 18 of the rubber cover 11, so that the rubber cover 11 can be taken out; when the first pressing rod 37 is reset, the vertical return spring drives the second positioning post 22 to move vertically upward, causing the second positioning post 22 to be reset and inserted again into the positioning groove 18 of the subsequent rubber cover 11.

[0044] To achieve precise lateral pushing, in this embodiment, a second motor 51 is used for driving to achieve slow and precise lateral feeding, thereby collecting precise friction force values and improving the detection accuracy.

[0045] Specifically, as Figure 5 shown, the lateral drive assembly 5 includes a second motor 51 installed on the first mounting plate 1, a transmission lead screw 52 installed at the end of the second motor 51, and a lead screw slider 53 sleeved on the transmission lead screw 52; a detection assembly 4 is installed on the lead screw slider 53, and a rotation indicating block 54 is also provided on one side of the second motor 51, and the rotation indicating block 54 indicates whether the second motor 51 is rotating; the transmission lead screw 52 and the lead screw slider 53 cooperate with each other to convert the rotational movement of the second motor 51 into a lateral linear reciprocating movement of the detection assembly 4.

[0046] Further, as Figure 5As shown, the detection component 4 further includes a vertical mounting block 42. The lower part of the vertical mounting block 42 is connected to a lead screw slider 53, and the upper part is mounted with a force sensor 41. A first U-shaped groove 43 for adjusting the vertical height of the force sensor 41 is provided on the vertical mounting block 42. The first U-shaped groove 43 can finely adjust the vertical height of the force sensor 41, so as to adapt to rubber caps 11 of different specifications, having a certain universality.

[0047] As Figure 2 shown, in order to achieve automatic feeding, a handling component 3 is installed at the front of the first mounting plate 1. The handling component 3 automatically transports the rubber caps 11 and the internal carbon crystals 12 inside. When the product is qualified, the product will be placed on the assembly line. When the product is unqualified, the product will be placed into the defective product pipeline 19, and the defective products will be collected through the defective product pipeline 19.

[0048] As Figure 2 and Figure 6 shown, the handling component 3 includes a first motor 31 installed on the first mounting plate 1 and a rotating plate 32 installed at the end of the first motor 31. Vertical mounting plates 33 are installed at both ends of the rotating plate 32. The number of the vertical mounting plates 33 is two, with a difference of 180°. In this embodiment, two workstations are set. In order to facilitate placing the defective products into the defective product pipeline 19, the rotating plate 32 rotates 90° each time. In order to improve efficiency, in other embodiments, multiple workstations can also be set to achieve rapid loading and unloading.

[0049] Furthermore, as Figure 6 shown, a first vertical cylinder 34 is installed on the upper part of the vertical mounting plate 33. A transverse clamping cylinder 35 is installed at the end of the first vertical cylinder 34. In order to maintain the stability of the vertical movement, a guide rail is installed on the vertical mounting plate 33, and a slider is sleeved on the guide rail. The transverse clamping cylinder 35 is installed on the slider. Transverse clamping claws 36 are installed at both ends of the transverse clamping cylinder 35. The transverse clamping cylinder 35 drives the transverse clamping claws 36 to clamp the rubber caps 11 and the internal carbon crystals 12 inside. In order to adapt to the external shape of the rubber caps 11, the inner sides of the transverse clamping claws 36 are arc-shaped. In order to prevent the rubber caps 11 from falling, a bottom supporting block 39 is installed at the lower part of the transverse clamping claws 36. The bottom supporting block 39 is inserted into the bottom of the rubber caps 11, so as to prevent the rubber caps 11 from falling vertically.

[0050] In order to facilitate clamping the rubber caps 11 on the assembly line, as Figure 6As shown in the figure, a first pressing rod 37 is fixedly installed on the side of the horizontal clamping cylinder 35. The first vertical cylinder 34 drives the first pressing rod 37 to move vertically downward to press down the first positioning column on the side of the rubber cover 11. The function and structure of the first positioning column are the same as those of the second positioning column 22, both of which are used to accurately position the rubber cover 11 and are inserted into the inside of the rubber cover 11.

[0051] The above structure can achieve automatic feeding, automatic longitudinal feeding, and lateral detection of friction force on both sides. However, the existing defect is that the detection error is relatively large. The reason is that during the assembly process of the rubber cover 11 and the carbon crystal 12, the position of the carbon crystal 12 is not fixed. It may be at the initial end, in the middle, or at the very end. As a result, the detection result is inaccurate and the error is relatively large. The most accurate detection method should be to detect from the initial end to the very end, collect the friction force values throughout the process, and then judge whether it is qualified. Therefore, the carbon crystal 12 should be reset before detection so that the carbon crystal 12 is at the initial end. At the same time, after the detection is completed, the carbon crystal 12 should also be reset so that the carbon crystal 12 is at the initial end, which is convenient for the assembly of the next process.

[0052] Therefore, in this embodiment, an opening component 92 is provided to drive the carbon crystal 12 inside the rubber cover 11 to move horizontally for resetting.

[0053] Specifically, for the convenience of the operation of the opening component 92, as Figure 7 shown, in this embodiment, a first vertical driving component 7 and a positioning component 8 are also provided. The first vertical driving component 7 drives the positioning component 8 to move vertically downward to vertically press and position the rubber cover 11 on the placing tray 2.

[0054] Furthermore, the positioning component 8 is also beneficial to improving the positioning accuracy and detection accuracy, thereby reducing the detection error.

[0055] As Figure 7 shown, a second mounting plate 14 is installed on the upper part of the first mounting plate 1. The second mounting plate 14 is fixedly connected to the first mounting plate 1 through a plurality of support columns 15. The first vertical driving component 7 is installed on the second mounting plate 14, and the positioning component 8 is installed on the first vertical driving component 7. The first vertical driving component 7 drives the positioning component 8 to move vertically downward to position the rubber cover 11 on the placing tray 2.

[0056] As Figure 8As shown, the first vertical drive assembly 7 includes a second vertical cylinder 71 mounted on the second mounting plate 14 and a third mounting plate 72 mounted at the end of the second vertical cylinder 71, and the third mounting plate 72 is mounted between the first mounting plate 1 and the second mounting plate 14; the first vertical drive assembly 7 also includes a guide rod 73 mounted on the third mounting plate 72 and a linear bearing 74 mounted on the second mounting plate 14, and the guide rod 73 is inserted into the linear bearing 74; the second vertical cylinder 71 drives the third mounting plate 72 to move vertically back and forth along the guide rod 73, and the linear bearing 74 is conducive to reducing the friction generated by the vertical movement of the guide rod 73.

[0057] like Figure 9 As shown, the positioning assembly 8 includes a first mounting block 81 installed at the bottom of the third mounting plate 72, and a positioning plate 82 is inserted into the first mounting block 81. The positioning plate 82 moves vertically back and forth inside the first mounting block 81 to facilitate subsequent elastic positioning and fixation.

[0058] like Figure 8 and Figure 9 As shown, the lower part of the positioning plate 82 is provided with a receiving groove 83 for accommodating the upper part of the rubber cover 11, and the receiving groove 83 is adapted to the upper part of the rubber cover 11; the positioning plate 82 is provided with the receiving groove 83, so that it can cover the upper part of the rubber cover 11 to achieve positioning and fixing of the rubber cover 11 on all sides.

[0059] Furthermore, in this embodiment, the positioning plate 82 fixes and positions the front and rear sides of the rubber cover 11 , leaving space on the left and right sides to facilitate detection by the detection component 4 .

[0060] like Figure 8 and Figure 9 As shown, a second U-shaped groove 84 is provided on the positioning plate 82, and a limiting rod 85 is installed on the first mounting block 81. The limiting rod 85 is inserted into the second U-shaped groove 84, and the positioning plate 82 can move vertically along the second U-shaped groove 84; further, a vertical spring is installed between the first mounting block 81 and the positioning plate 82. The positioning plate 82 moves vertically downward under the drive of the second vertical cylinder 71 to compress the vertical spring, so that the vertical spring has a certain elastic force inside, which can drive the positioning plate 82 to position and fix the rubber cover 11 on the placement tray 2, thereby realizing elastic positioning and fixation.

[0061] In order to confirm or detect the specifications of the rubber cover 11 , in this embodiment, the vertical height of the rubber cover 11 is detected. Rubber covers 11 of different specifications have different vertical heights.

[0062] Specifically, such as Figure 8 and Figure 9As shown, the positioning component 8 further includes a detection block 86 installed at the end of the first mounting block 81. A photoelectric switch 88 is installed at the lower part of the detection block 86. A third U-shaped groove 87 for adjusting the vertical height is provided on the detection block 86, and the third U-shaped groove 87 is used to adjust the vertical height of the detection block 86 and the photoelectric switch 88.

[0063] Further, one end of the positioning plate 82 is inserted into the photoelectric switch 88. A height detection groove 89 is provided at one end of the positioning plate 82. If the height detection groove 89 is in the correct position, the signal of the photoelectric switch 88 will pass through the inside of the height detection groove 89 smoothly.

[0064] Furthermore, if the specification of the rubber cover 11 does not meet the requirements, the rubber cover 11 has an incorrect vertical height. After the positioning plate 82 is positioned, the height detection groove 89 is not at the correct vertical height. Then the signal of the photoelectric switch 88 cannot pass through the inside of the height detection groove 89 smoothly, so as to determine that the specification of the rubber cover 11 is incorrect.

[0065] When it is necessary to change the specification of the rubber cover 11, it is necessary to adjust the vertical height of the detection block 86 and the photoelectric switch 88. The adjustment can be carried out through the third U-shaped groove 87, and the vertical height of the detection block 86 and the photoelectric switch 88 can be increased or decreased.

[0066] As Figure 7 shown, a second vertical driving component 91 is further installed on the first vertical driving component 7. The second vertical driving component 91 is arranged on the opposite side of the positioning component 8. In this embodiment, the second vertical driving component 91 and the positioning component 8 are arranged opposite to each other.

[0067] As Figure 7 shown, an opening component 92 is installed on the second vertical driving component 91. As Figure 10 shown, the second vertical driving component 91 drives the opening component 92 to vertically insert into the rubber cover 11, and the opening component 92 drives the carbon crystal 12 inside the rubber cover 11 to move horizontally for resetting.

[0068] As Figure 10 and Figure 11 shown, the second vertical driving component 91 includes a third vertical cylinder 93 installed on the third mounting plate 72 and a second mounting block 94 installed at the end of the third vertical cylinder 93. The third vertical cylinder 93 drives the second mounting block 94 and the opening component 92 to move vertically back and forth.

[0069] As Figure 10 and Figure 11As shown, the opening assembly 92 includes a lateral opening cylinder 95 installed on the second mounting block 94 and opening jaws 96 installed at both ends of the lateral opening cylinder 95; the opening jaws 96 are in a broken line shape, formed by three right-angle bends, and their ends extend deep into the inside of the rubber cover 11; the lateral opening cylinder 95 drives the opening jaws 96 to laterally push the carbon crystal 12 inside the rubber cover 11 to reset the carbon crystal 12.

[0070] For better fixation and positioning, the accommodation groove 83 can accommodate the opening jaws 96 inside, so that the positioning plate 82 can span across the front and back sides of the rubber cover 11 for fixation and positioning.

[0071] As Figure 11 As shown, the strokes of the lateral opening cylinders 95 are all small, and limit blocks 97 are installed on the sides to hard-limit the strokes of the opening jaws 96 to prevent damage to the rubber cover 11; outer limit protrusions 98 are provided at both ends of the limit blocks 97, and inner limit protrusions 99 are provided inside. The opening jaws 96 are arranged between the outer limit protrusions 98 and the inner limit protrusions 99, and are laterally limited by the outer limit protrusions 98 and internally limited by the inner limit protrusions 99.

[0072] The operating steps of the carbon crystal detection device:

[0073] Step S1: The handling assembly 3 automatically transports the rubber cover 11 and the carbon crystal 12 inside from the production line; the first vertical cylinder 34 drives the first pressing rod 37 to move vertically, and the first pressing rod 37 presses down the first positioning post on the side of the rubber cover 11; the lateral clamping cylinder 35 drives the lateral clamping jaws 36 to clamp the rubber cover 11 and the carbon crystal 12 inside; the first motor 31 drives the rotating plate 32 to rotate 90° twice to place the rubber cover 11 above the placement tray 2.

[0074] Step S2: The first vertical cylinder 34 drives the first pressing rod 37 to move vertically, and the first pressing rod 37 presses the second positioning post 22 on the placement tray 2. The lateral clamping cylinder 35 drives the lateral clamping jaws 36 to loosen the rubber cover 11, and the bottom of the rubber cover 11 fits the placement groove 21; the first vertical cylinder 34 resets vertically upward, and the vertical return spring drives the second positioning post 22 to move vertically upward, so that the second positioning post 22 is reset and inserted again into the positioning groove 18 of the subsequent rubber cover 11; realizing the stable placement and accurate positioning of the rubber cover 11.

[0075] Step S3: The first longitudinal cylinder 61 drives the longitudinal slider 62, the placement tray 2, the rubber cover 11, and the carbon crystal 12 to move longitudinally along the longitudinal guide rail 63, moving the placement tray 2 below the positioning assembly 8, and the force sensor 41 corresponds to the carbon crystal 12.

[0076] Step S4: The second vertical cylinder 71 drives the third mounting plate 72 to move vertically downward along the guide rod 73, and the positioning plate 82 also moves downward to cover the upper part of the rubber cover 11. The accommodation groove 83 is adapted to the upper part of the rubber cover 11. The positioning plate 82 fixes and positions the front and rear sides of the rubber cover 11, leaving spaces on the left and right sides to facilitate the detection by the detection component 4.

[0077] Step S5: The positioning plate 82 can move vertically along the second U-shaped groove 84 to compress the internal vertical spring. If the vertical height of the rubber cover 11 is correct, then the signal of the opposed switch 88 will pass smoothly through the inside of the height detection groove 89.

[0078] Step S6: The third vertical cylinder 93 drives the second mounting block 94 and the opening component 92 to move vertically downward. The opening jaws 96 at the end of the opening component 92 are inserted into the rubber cover 11.

[0079] Step S7: The lateral opening cylinder 95 drives the opening jaws 96 to laterally push the carbon crystal 12 inside the rubber cover 11 to reset the carbon crystal 12 so that the carbon crystal 12 is at the initial end.

[0080] Step S8: The opening jaws 96 are reset. The second motor 51 drives the force sensor 41 at the end to move laterally. The force sensor 41 contacts the carbon crystal 12 and pushes the carbon crystal 12 to move laterally inside the rubber cover 11 to detect the frictional force generated by the lateral movement of the carbon crystal 12 inside the rubber cover 11. The carbon crystal 12 is pushed to the outermost end to collect the frictional force values throughout the process, and then to determine whether the lateral movement of the carbon crystal 12 inside the rubber cover 11 is smooth or slippery and whether the frictional force exceeds the target standard.

[0081] Step S8: The force sensor 41 is reset. The lateral opening cylinder 95 drives the opening jaws 96 to laterally push the carbon crystal 12 inside the rubber cover 11 to reset the carbon crystal 12 so that the carbon crystal 12 is at the initial end.

[0082] Step S9: The first longitudinal cylinder 61 drives the longitudinal slider 62, the placement tray 2, the rubber cover 11, and the carbon crystal 12 to move longitudinally along the longitudinal guide rail 63 to longitudinally send out the placement tray 2, the rubber cover 11, and the carbon crystal 12 to below the lateral gripper 36 for the lateral gripper 36 to pick up and the handling component 3 to perform automatic handling. If the rubber cover 11 and the carbon crystal 12 are assembled qualified, they are placed on the assembly line for the assembly of the next process. If the rubber cover 11 and the carbon crystal 12 are assembled unqualified, they are placed into the defective product pipeline 19 for the collection of defective products through the defective product pipeline 19.
