Technical Field

[0001] The present application relates to the technical field of glue dispensing equipment, and in particular to a glue dispensing equipment for a masking glue dispensing process. Background Art

[0002] At present, in China, the pre-anodizing protection treatment of products is usually achieved by sticking high-temperature tape. The process is relatively complicated, and the color transition of the surface after the anode is not natural enough. The current research and development direction uses UV glue to form a shielding area at the split, and then sandblasts the unshielded area, performs the first anodizing and dyeing treatment, and then uses a remover to remove the UV glue to achieve anodizing treatment. However, due to the shape of the product or the nature of the glue, it is easy to cause the dispensing accuracy of the masking glue to be low, affecting the subsequent product processing. Summary of the invention

[0003] In order to improve the above-mentioned problems, the present application provides a dispensing device for a masking dispensing process.

[0004] The present application provides a dispensing device for a masking dispensing process using the following technical solutions: A glue dispensing device for a masking glue dispensing process comprises an equipment frame, an X-axis glue dispensing mechanism, a Z-axis glue dispensing mechanism, a Y-axis glue dispensing mechanism, a rotating mechanism and a glue erasing mechanism; the equipment frame comprises a base and a mounting frame, the mounting frame is mounted on the top of the base in a vertical direction; the Y-axis glue dispensing mechanism and the glue erasing mechanism are both mounted on the top surface of the base; the X-axis glue dispensing mechanism is mounted on the mounting frame; the Z-axis glue dispensing mechanism is mounted on the moving end of the X-axis glue dispensing mechanism, and the moving end of the Z-axis glue dispensing mechanism is provided with a glue dispensing head, and the glue dispensing head applies masking glue to the product; the rotating mechanism is mounted on the moving end of the Y-axis glue dispensing mechanism, and the rotating mechanism is provided with a clamping piece for fixing the product, and the clamping piece is provided with rotation, and the glue erasing mechanism is located within the rotation range.

[0005] By adopting the above technical solution, after the product is installed on the clamping part, it can be driven by the Y-axis dispensing mechanism to move forward and backward. At the same time, it can also be driven by the rotating mechanism to rotate during the movement. Cooperating with the dispensing head that moves horizontally and up and down, multi-axis linkage operation dispensing is realized to ensure the stability of the product when the masking glue is applied. The rotating action of the rotating mechanism is used to rotate the product to the wiping mechanism, and the wiping mechanism wipes the product on the clamping part to erase the masking glue that adheres to the product and does not appear in the masking range, thereby ensuring the integrity of the product.

[0006] Optionally, the moving end of the Z-axis dispensing mechanism is also provided with an identification mechanism.

[0007] By adopting the above technical solution, the identification mechanism is used to identify the dispensing conditions on the product and the integrity of the glue wiping. The dispensing direction of the identification mechanism is consistent with that of the dispensing head. While the dispensing head is continuously dispensing glue, the identification mechanism synchronously identifies whether there are errors or omissions in the dispensing.

[0008] Optionally, the recognition mechanism includes a first CCD recognition component and an AOI detection component.

[0009] By adopting the above technical solution, using the first CCD identification component and the AOI detection component, it can move up and down synchronously with the moving end of the Z-axis dispensing mechanism, and move horizontally synchronously with the moving end of the X-axis dispensing mechanism, and cooperate with the synchronous Y-axis dispensing mechanism and the rotating mechanism to rotate the product, so that the product can obtain comprehensive identification and detection during the dispensing process, preventing dispensing errors, omissions, etc., and improving the accuracy and stability of dispensing masking glue.

[0010] Optionally, the moving end of the Z-axis dispensing mechanism is also provided with a UV curing lamp.

[0011] By adopting the above technical solution, after the dispensing head dispenses glue on the product, the UV curing lamp is turned on simultaneously to cure the part of the product that has just been glued, so as to achieve the effect of curing while dispensing, reduce glue flow, and improve the accuracy of glue dispensing.

[0012] Optionally, the erasing mechanism includes a connecting seat, a guide wheel, a first pivot wheel, a first driving member and a wiping belt; a connecting plate is provided on the connecting seat, the first driving member is installed on the connecting seat, and the driving end passes through the connecting plate; the first pivot wheel is connected to the driving end of the first driving member; the guide wheel is installed on the connecting plate; the wiping belt is sleeved on the first pivot wheel and several of the guide wheels, and the first pivot wheel is driven by the first driving member to drive the wiping belt to rotate along the first pivot wheel and the guide wheel.

[0013] By adopting the above technical solution, the product moves to the wiping belt along with the rotating mechanism and the clamping member, and is located at the wiping belt position between the guide wheel and the first pivot wheel. As the first driving member drives the first pivot wheel to rotate, the wiping belt is driven to rotate between the first pivot wheel and the guide wheel. The wiping belt contacts the surface of the product during the rotation, thereby wiping the excess glue spots attached to the surface of the product.

[0014] Optionally, the wiping mechanism also includes a second pivot wheel and a second driving member; a plurality of guide wheels are provided and mounted on the connecting plate; the second driving member is mounted on the connecting seat, and the driving end passes through the connecting plate; the second pivot wheel is connected to the driving end of the second driving member; one end of the wiping belt is connected to the first pivot wheel, and the other end bypasses a plurality of guide wheels and is connected to the second pivot wheel, and the wiping belt is wrapped around the first pivot wheel or the second pivot wheel.

[0015] By adopting the above technical solution, when the first driving member drives the first pivot wheel to rotate, the wiping belt is wound along the first pivot wheel, and the other end is released from the second pivot wheel. The second driving member can synchronously drive the second pivot wheel to rotate, so that the wiping belt can be stably wound around the first pivot wheel. During the winding process, the product can contact the wiping belt to wipe the residual glue points, and vice versa. This method increases the loading length of the wiping belt to increase the service life of the wiping belt.

[0016] Optionally, the wiping mechanism further comprises a tensioning member, wherein the tensioning member is mounted on the connecting plate and abuts against the wiping belt.

[0017] By adopting the above technical solution, the tensioning member can press against a part of the wiping belt, so that the tension of the wiping belt is stabilized.

[0018] Optionally, a guide rail is also provided on the base; a slider is provided on the guide rail; the identification mechanism also includes a second CCD identification component, which is connected to the top of the slider; the first pivot wheel is connected to a first winding wheel on the side away from the connecting plate; the second pivot wheel is connected to a second winding wheel on the side away from the connecting plate; the first winding wheel is connected to a first linkage rope, one end of the first linkage rope is wound around the first winding wheel, and the other end is connected to one end of the slider; the second winding wheel is connected to a second linkage rope, one end of the second linkage rope is wound around the second winding wheel, and the other end is connected to the other end of the slider.

[0019] By adopting the above technical solution, when the first winding wheel rotates with the first pivot wheel, the first linkage rope is wound, and the slider is synchronously driven to move toward the first winding wheel, and the second winding wheel synchronously releases the second linkage rope. Conversely, when the second winding wheel rotates in the opposite direction with the second pivot wheel, the second linkage rope is wound, and the second linkage rope pulls the slider to move along the guide rail toward the second winding wheel. The movement of the slider changes the recognition position of the second CCD identification component, so that the second CCD identification component can perform CCD recognition detection on the product through different positions.

[0020] Optionally, the second CCD identification component is connected to the slider by hinge; a V-shaped limit block is also provided on the top of the slider; when the second CCD identification component is tilted along the hinge point, it abuts against any side of the limit block; the bases at both ends of the guide rail are also provided with relatively arranged pushing parts, and when the slider moves to the pushing part at the corresponding end, the pushing part pushes the second CCD identification component to tilt in the direction of the other pushing part.

[0021] By adopting the above technical solution, the second CCD identification component utilizes the pushing part moved to either end of the guide rail and is pushed by the pushing part to tilt in the opposite direction along the hinge point, so as to adjust the inclination angle of the second CCD identification component, and provide limitation for the second CCD identification component through a V-shaped limit block to prevent the second CCD identification component from continuing to tilt to one side. When the second CCD identification component tilts in any direction, the recognition angle can be adjusted to ensure all-round CCD recognition of the product.

[0022] Optionally, the bases at both ends of the guide rail are further provided with wire portions, and the first linkage rope and the second linkage rope both pass around the wire portions and are connected to the slider.

[0023] By adopting the above technical solution, the first linkage rope and the second linkage rope can be longer by passing through the wire loop, so as to adapt to the longer wiping belt. At the same time, the length of the guide rail is also longer, which is convenient for the second CCD identification component to provide CCD identification from more angles, and the identification information obtained is more complete, providing a more accurate identification image.

[0024] In summary, the present application includes at least one of the following beneficial technical effects: 1. After the product is installed on the clamp, it can be driven by the Y-axis dispensing mechanism to move forward and backward. At the same time, it can also be driven by the rotating mechanism to rotate during the movement. With the dispensing head that moves horizontally and up and down, multi-axis linkage operation dispensing is realized to ensure the stability of the product when dispensing masking glue. The product is rotated to the wiping mechanism by using the rotation effect of the rotating mechanism. The wiping mechanism wipes the product on the clamp to wipe off the masking glue that is attached to the product and does not appear in the masking range, ensuring the integrity of the product. 2. The identification mechanism is used to identify the dispensing conditions on the product and the integrity of the glue wiping. The dispensing direction of the identification mechanism is consistent with that of the dispensing head.

[0031] The following is combined with Figure 1 -Attached Figure 6 , further details of this application are given.

[0032] The embodiment of the present application discloses a glue dispensing device for a masking glue dispensing process.

[0033] A dispensing device for a masking dispensing process is used for dispensing masking glue on products and provides wiping work for non-dispensing ranges after dispensing to ensure accurate positioning of the masking glue.

[0034] refer to Figure 1 As shown, the dispensing equipment includes an equipment frame 1, an X-axis dispensing mechanism 2, a Z-axis dispensing mechanism 4, a Y-axis dispensing mechanism 3, a rotating mechanism 5 and a wiping mechanism 6; a frame shell can also be installed on the outside of the equipment frame 1 to provide dust and anti-static effects and protection during dispensing. The equipment frame 1 includes a base 11 and a mounting frame 12. The base 11 is a base structure, which provides horizontal installation and placement. The mounting frame 12 is installed on the top of the base 11 along the vertical direction to provide vertical installation and placement.

[0035] The Y-axis dispensing mechanism 3 and the wiping mechanism 6 are both installed on the top surface of the base 11, and the X-axis dispensing mechanism 2 is installed on the mounting frame 12; the Z-axis dispensing mechanism 4 is installed on the moving end of the X-axis dispensing mechanism 2, and the moving end of the Z-axis dispensing mechanism 4 is provided with a dispensing head 41, wherein the structures of the X-axis dispensing mechanism 2, the Y-axis dispensing mechanism 3 and the Z-axis dispensing mechanism 4 are similar, and all are driven by a moving rail and a drive chain structure, or a screw rod and a motor structure, but the driving directions of the X-axis dispensing mechanism 2, the Y-axis dispensing mechanism 3 and the Z-axis dispensing mechanism 4 are different, such as the driving direction of the X-axis dispensing mechanism 2 provides drive along the horizontal straight line direction, the Y-axis dispensing mechanism 3 provides drive along the front and rear direction of the attached figure, and the Z-axis dispensing mechanism 4 provides drive up and down in the vertical direction.

[0036] The moving end of the X-axis dispensing mechanism 2 can drive the Z-axis dispensing mechanism 4 to move in the horizontal direction. The moving end of the Z-axis dispensing mechanism 4 is connected to a dispensing head 41. The dispensing head 41 is connected to a connecting hose. The connecting hose is externally connected to a glue storage device, such as a glue barrel, to provide glue supply during dispensing. The moving end of the Z-axis dispensing mechanism 4 drives the dispensing head 41 to move up and down, and cooperates with the X-axis dispensing mechanism 2 to drive the Z-axis dispensing mechanism 4 to move horizontally, so that the dispensing head 41 can adjust the dispensing position and stably dispense glue to the product.

[0037] The rotating mechanism 5 is installed at the moving end of the Y-axis dispensing mechanism 3. The Y-axis dispensing mechanism 3 can drive the rotating mechanism 5 to move in the front and rear directions. A clamping part 51 for fixing the product is provided on the rotating mechanism 5. The rotating mechanism 5 can adopt a structure of a motor and a driving shaft. The clamping part 51 is located on the driving shaft. The motor is driven to rotate to provide the clamping part 51 with rotation. After the product is installed on the clamping part 51, it can be driven by the Y-axis dispensing mechanism 3 to move forward and backward. At the same time, it can also be driven by the rotating mechanism 5 to rotate during the movement. In conjunction with the dispensing head 41 that moves horizontally and up and down, multi-axis linkage operation dispensing is realized to ensure the stability of the product masking glue dispensing.

[0038] The glue wiping mechanism 6 is located on one side of the Y-axis dispensing mechanism 3. The rotating end of the rotating mechanism 5 is connected to a rotating arm, which is extended along the moving direction of the X-axis dispensing machine, so that when the clamping member 51 rotates, the extended rotating arm can be used to extend to the wiping mechanism. The wiping mechanism wipes the product on the clamping member 51 to erase excess masking glue in the non-shielded area of ​​the product, thereby ensuring the integrity of the product and not affecting subsequent processing.

[0039] The dispensing head 41 is connected to a heated piezoelectric spray valve, and continuous operation can ensure the consistency of dispensing.

[0040] In some embodiments, reference Figure 1 As shown, the moving end of the Z-axis dispensing mechanism 4 is also provided with an identification mechanism 7, and the identification end is facing the base 11. The identification mechanism 7 is used to identify the dispensing condition of the masking glue on the product and the integrity of the wiping glue. Therefore, the identification end is facing the base 11, which is consistent with the dispensing direction of the dispensing head 41. While the dispensing head 41 is continuously dispensing glue, the identification mechanism 7 synchronously identifies whether there are any errors or omissions in the dispensing of the masking glue.

[0041] For further reference, Figure 2 As shown, the recognition mechanism 7 includes a first CCD recognition component 71 and an AOI detection component 72 , and the first CCD recognition component 71 and the AOI detection component 72 are respectively located on both sides of the dispensing head 41 .

[0042] The appearance of the product is detected through the display and controller through the first CCD identification component 71. The CCD adopts silicon-based semiconductor processing technology. The electric field generated by the electrode drives the charge to be transmitted to the central analog-to-digital converter in the controller in a linked manner. The high-resolution first CCD identification component 71 can accurately identify the marking points of the product and the masking glue dispensing track to ensure the dispensing accuracy and quality. It can adaptively adjust with the product's own tolerance to ensure the dispensing quality while also being able to detect the glue type after dispensing.

[0043] The AOI inspection component 72 uses camera technology to output the reflected light intensity of the inspected object in a quantitative grayscale value. By comparing it with the grayscale value of the standard image, it analyzes and determines the defects and classifies them. It can detect defects on the product and is suitable for inspections from high-density to low-density spacing. At the same time, different color inspections can be used for different colors to accommodate products of different colors.

[0044] By utilizing the first CCD identification component 71 and the AOI detection component 72, it can move up and down synchronously with the moving end of the Z-axis dispensing mechanism 4, and move horizontally synchronously with the moving end of the X-axis dispensing mechanism 2, and cooperate with the synchronous Y-axis dispensing mechanism 3 and the rotating mechanism 5 to rotate the product, so that the product can be fully identified and detected during the dispensing process, preventing dispensing errors, omissions, etc., and improving accuracy and stability.

[0045] In some embodiments, reference Figure 2 As shown, the moving end of the Z-axis dispensing mechanism 4 is also provided with a UV curing lamp 8. The UV curing lamp 8 can rise and fall in the vertical direction following the moving end of the Z-axis dispensing mechanism 4, and rise and fall synchronously with the dispensing head 41. After the dispensing head 41 dispenses glue on the product, the UV curing lamp 8 is turned on synchronously to cure the part of the product that has just been glued, so as to achieve the effect of curing while dispensing, reducing glue flow, and improving the accuracy of dispensing.

[0046] In some embodiments, reference Figure 3 As shown, the erasing mechanism 6 includes a connecting seat 61, a guide wheel 62, a first pivot wheel 63, a first driving member 64 and a wiping belt 65; a connecting plate 611 is provided on the connecting seat 61, the first driving member 64 is installed on the connecting seat 61, and the driving end passes through the connecting plate 611, and a supporting foot is provided at the bottom of the connecting seat 61, and the connecting seat 61 is lifted to a certain height by the supporting foot to ensure that the height is sufficient for the product to approach, and the connecting plate 611 is installed on the connecting seat 61 in the vertical direction, and the connecting plate 611 separates the rotating mechanism 5 to prevent the rotating mechanism 5 or the dispensing head 41 from affecting the first driving member 64.

[0047] The first driving member 64 may be a driving motor, and a pivot opening or a pivot bearing may be provided on the connecting plate 611 so that the driving end of the driving motor can penetrate the connecting plate 611 and extend toward the rotating mechanism 5 .

[0048] The first pivot wheel 63 is connected to the driving end of the first driving member 64 . A rubber layer may be provided on the surface of the first pivot wheel 63 to increase friction. The first pivot wheel 63 can rotate following the driving end of the first driving member 64 .

[0049] The guide wheel 62 is installed on the connecting plate 611. The guide wheel 62 can provide guidance for the wiping belt 65. The wiping belt 65 is sleeved on the first pivot wheel 63 and the guide wheel 62. The first pivot wheel 63 is driven by the first driving member 64 to drive the wiping belt 65 to rotate along the first pivot wheel 63 and the guide wheel 62. During the rotation, the location where the product needs to be wiped contacts the wiping belt 65, so that the masking glue of the product outside the dispensing range of the masking glue can be wiped off.

[0050] The wiping tape 65 may be a dust-free cloth, and both the front and back sides of the dust-free cloth may be used.

[0051] The first pivot wheel 63 is provided with an annular groove, and the wiping belt 65 is located in the annular groove. The annular groove is used for limiting the position to prevent the wiping belt 65 from being separated from the first pivot wheel 63 .

[0052] Specifically, the product moves with the rotating mechanism 5 and the clamping member 51 to the wiping belt 65, and is located at the position of the wiping belt 65 between any guide wheel 62 and the first pivot wheel 63. As the first driving member 64 drives the first pivot wheel 63 to rotate, the wiping belt 65 is driven to rotate between the first pivot wheel 63 and the guide wheel 62. The wiping belt 65 contacts the surface of the product during the rotation, thereby wiping the masking glue on the surface of the product that is outside the dispensing range of the masking glue.

[0053] In another embodiment, reference Figure 4 As shown, the wiping mechanism also includes a second pivot wheel 66 and a second driving member 67; the second driving member 67 is installed on the connecting seat 61, and the driving end passes through the connecting plate 611, the second pivot wheel 66 is connected to the driving end of the second driving member 67, the second driving member 67 is consistent with the first driving member 64, and both can use a driving motor. The second pivot wheel 66 is the same style as the first pivot wheel 63 and can be adjusted in size, which will not be repeated here.

[0054] One end of the wiping belt 65 is connected to the first pivot wheel 63, and the other end passes around a number of guide wheels 62 and is connected to the second pivot wheel 66, and the wiping belt 65 is wound around the first pivot wheel 63 or the second pivot wheel 66. The length of the wiping belt 65 can be set to be very long, so that the first pivot wheel 63 and the second pivot wheel 66 can both wrap the wiping belt 65. This method can increase the service life of the wiping belt 65 and reduce the need for replacement.

[0055] Specifically, when the first driving member 64 drives the first pivot wheel 63 to rotate, the wiping belt 65 is wound along the first pivot wheel 63, and the other end is loosened from the second pivot wheel 66. The second driving member 67 can synchronously drive the second pivot wheel 66 to rotate, so that the wiping belt 65 can be stably wound around the first pivot wheel 63. During the winding process, the product can contact the wiping belt 65 to wipe the residual glue points. Conversely, the second driving member 67 drives the second pivot wheel 66 to rotate in the opposite direction, so that the wiping belt 65 is gradually loosened from the winding state on the first pivot wheel 63 and is wound around the second pivot wheel 66, so that the loading length of the wiping belt 65 is increased to increase the service life of the wiping belt 65.

[0056] When the first driving member 64 rotates, the second driving member 67 can rotate synchronously, and vice versa, to avoid insufficient tension when contacting the product. Any driving member is used to limit the rotation speed to ensure the stability of the tension.

[0057] For further reference, Figure 4 As shown, the wiping mechanism also includes a tensioning member 68, which is installed on the connecting plate 611 and abuts against the wiping belt 65. The tensioning member 68 can adopt an elastic tensioning plate or a tensioning electric push rod. The tensioning member can abut against a part of the wiping belt 65 to stabilize the tension of the wiping belt 65.

[0058] Further, refer to Figure 4 As shown, the tensioning member 68 is also connected to a cleaning member 69. The tensioning member 68 can be a tensioning electric push rod. The electric push rod is installed on the connecting plate 611 in the vertical direction, and the extended end is in contact with the wiping belt 65. At the same time, the cleaning member 69 is installed at the extended end of the electric push rod. The cleaning member 69 can be a nozzle. A delivery hose is connected to the nozzle. The delivery hose is connected to an external liquid storage cylinder for delivering cleaning liquid. The cleaning liquid can be IPA or other cleaning chemicals, which are not specifically limited here. IPA is isopropyl alcohol. A cleaning wiping belt 65 is provided.

[0059] When the tensioning member 68 is against the wiping belt 65, the nozzle can spray IPA or other cleaning liquid in the direction of the wiping belt 65. Combined with the friction between the wiping belt 65 and the tensioning member 68, the cleaning liquid can be stably attached to the wiping belt 65 to clean the residual glue spots wiped off by the wiping belt 65, thereby further improving the service life of the wiping belt 65.

[0060] In some embodiments, reference Figure 5 As shown, a guide rail 111 is also provided on the base 11; a slider 112 is provided on the guide rail 111, and the identification mechanism 7 also includes a second CCD identification component 73, and the second CCD identification component 73 is connected to the top of the slider 112. The installation direction of the guide rail 111 is consistent with the installation direction of the Y-axis dispensing structure, and the slider 112 can slide along the guide rail 111. The second CCD identification component 73 has the same structure as the first CCD identification component 71, and both can provide image recognition detection. The slider 112 is moved along the guide rail 111, so that the second CCD identification component 73 can change the recognition position, so that each position of the product can be identified, further ensuring that the product dispensing and wiping are sufficient and complete.

[0061] The first pivot wheel 63 is connected to a first winding wheel 631 on a side away from the connecting plate 611, the second pivot wheel 66 is connected to a second winding wheel 661 on a side away from the connecting plate 611, the first winding wheel 631 is connected to a first linkage rope 632, one end of the first linkage rope 632 is wound around the first winding wheel 631, and the other end is connected to one end of the slider 112, when the first pivot wheel 63 rotates, it can synchronously drive the first winding wheel 631 to rotate, the rotation of the first winding wheel 631 can release or wind the first linkage rope 632, when winding, the first linkage rope 632 can pull the slider 112 to move along the guide rail 111 toward the first pivot wheel 63.

[0062] The second winding wheel 661 is connected to the second linkage rope 662. One end of the second linkage rope 662 is wound around the second winding wheel 661, and the other end is connected to the other end of the slider 112. When the second pivot wheel 66 rotates, it can synchronously drive the second winding wheel 661 to rotate. The rotation of the second winding wheel 661 can release or wind the second linkage rope 662. When winding, the second linkage rope 662 can pull the slider 112 to move along the guide rail 111 toward the second pivot wheel 66.

[0063] Therefore, when the first winding wheel 631 rotates with the first pivot wheel 63, the first linkage rope 632 is wound, and the slider 112 is synchronously driven to move toward the first winding wheel 631, and the second winding wheel 661 synchronously releases the second linkage rope 662. Conversely, when the second winding wheel 661 rotates in the opposite direction with the second pivot wheel 66, the second linkage rope 662 is wound, and the second linkage rope 662 pulls the slider 112 to move along the guide rail 111 toward the second winding wheel. The movement of the slider 112 changes the recognition position of the second CCD identification component 73, so that the second CCD identification component 73 can perform CCD recognition detection on the product through different positions.

[0064] Furthermore, the second CCD identification member 73 is connected to the slider 112 by hinged connection, that is, a hinge frame can be set between the second CCD identification member 73 and the slider 112 for connection, and the second CCD identification member 73 can adjust the identification angle along the hinge frame to ensure full-range CCD identification of the product.

[0065] A V-shaped limit block 113 is also provided on the top of the slider 112. When the second CCD identification component 73 tilts along the hinge point, it abuts against any side of the limit block 113. The V-shaped limit block 113 enables the second CCD identification component 73 to abut against any surface of the V-shaped limit block 113 when it tilts to any side along the hinge point, thereby limiting the second CCD identification component 73 and preventing the second CCD identification component 73 from continuing to tilt to one side.

[0066] refer to Figure 5 As shown, the base 11 at both ends of the guide rail 111 is also provided with a pushing portion 13 arranged opposite to each other. When the slider 112 moves to the pushing portion 13 at the corresponding end, the pushing portion 13 pushes the second CCD identification component 73 to tilt toward the other pushing portion 13. The pushing portion 13 can adopt an inverted L-shaped connecting frame, and the height of the pushing portion 13 is consistent with the height of the second CCD identification component 73, or slightly lower than the second CCD identification component 73, to ensure that when the slider 112 moves along the guide rail 111 to the pushing portion 13, the pushing portion 13 can push the second CCD identification component 73 in the opposite direction, so that the tilt direction of the second CCD identification component 73 changes, thereby adjusting the tilt angle of the second CCD identification component 73.

[0067] Specifically, the second CCD identification component 73 utilizes the pushing part 13 moved to either end of the guide rail 111 and is pushed by the pushing part 13 to tilt in the opposite direction along the hinge point, so as to adjust the inclination angle of the second CCD identification component 73, and provide a limit for the second CCD identification component 73 through the V-shaped limit block 113 to prevent the second CCD identification component 73 from continuing to tilt to one side. When the second CCD identification component 73 tilts in any direction, the recognition angle can be adjusted to ensure that all-round CCD recognition is provided for the product.

[0068] Further, refer to Figure 5 and Figure 6 As shown, a wire portion 14 is also provided on the base 11 at both ends of the guide rail 111, and the first linkage rope 632 and the second linkage rope 662 are both connected to the slider 112 by passing through the wire portion 14. The wire portion 14 can be composed of a plurality of wire loops. The first linkage rope 632 and the second linkage rope 662 pass through the wire loops so that the length of the first linkage rope 632 and the second linkage rope 662 can be longer, adapted to a longer wiping belt 65, and also make the length of the guide rail 111 longer, so that the second CCD identification component 73 can provide CCD identification from more angles, obtain more complete identification information, and provide a more accurate identification image.

The same components are represented by the same figure marks. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the protection scope of the present application.
