DETAILED DESCRIPTION

[0021] Embodiment 1: See also Figures 1 to 5 The embodiment of the present invention provides a fixing device for producing an integrated computer monitor back cover, which is mainly used to simplify the structural design and form a linkage between the structures. The device includes a platform 1, which is cylindrical in design and has an opening facing upward. Two limit assemblies 4 for realizing the limit of the back cover are arranged above the platform 1. The opposite sides of the two limit assemblies 4 are both driven and arranged with moving assemblies 5. The platform 1 is provided with an adjusting assembly 2 that is movably fitted with the two moving assemblies 5. The platform 1 is also provided with a control assembly 3 for driving the two limit assemblies 4 and the two moving assemblies 5 to rotate synchronously.

[0022] When the control component 3 drives the limiting component 4 and the moving component 5 to move, wherein the movement is along the circumferential direction of the platform 1, the rear cover can be automatically limited and automatically flipped 180 degrees by the adjusting component 2, and the displacement of the rear cover can be effectively avoided during the movement; it can also realize the automatic release of the limit on the rear cover, thereby realizing the quick removal and placement of the rear cover.

[0023] In this embodiment, two camera detection modules (not shown in the figure) can be provided on the front and rear sides of the platform 1 in actual application, one of which is used to detect the front side of the back cover, and the other is used to detect the back side exposed after the back cover is flipped 180 degrees; here, the camera detection module is an existing mature technology and will not be described in detail here.

[0024] Reference Figure 2 and Figure 5In this embodiment, preferably: the control component 3 includes a motor 301 fixedly connected to the platform 1, and the output shaft of the motor 301 is fixedly installed with a cantilever 302, the cantilever 302 has two ends, one of which extends from the center of the platform 1 and the other end is L-shaped and movably fits with the outer surface of the platform 1, and the two end surfaces of the cantilever 302 are rotatably installed with a cross bar 303 fixedly connected to the limit assembly 4.

[0025] When the motor 301 is started, the cantilever 302 can be driven to rotate. The cantilever 302 drives the two cross bars 303 to move synchronously through the two ends, thereby causing the two limit assemblies 4 and the two moving assemblies 5 to move along the circumferential direction of the platform 1 .

[0026] Reference Figures 2 to 4 In this embodiment, preferably: the limit assembly 4 includes a bracket 401 fixedly connected to the crossbar 303 and two bases 402 attached to the surface of the bracket 401, and the two bases 402 are elastically connected to the guide column 403 on the opposite side through a spring (not shown in the figure), and the spring makes the guide column 403 have a tendency to slide out from the base 402, and the guide column 403 is used to support the back cover. The bracket 401 is internally rotatably installed with a tooth column 405 that is transmission-connected to the moving assembly 5, and the surfaces of the two bases 402 are fixedly installed with vertical racks 404 that are transmission-connected to the tooth column 405.

[0027] In the above structure, the two vertical racks 404 are arranged in an up-and-down staggered manner based on the tooth column 405, so that the two vertical racks 404 move in opposite directions based on the tooth column 405. When the moving component 5 drives the tooth column 405 to rotate, the tooth column 405 can drive the two bases 402 to move relatively close or away through the two vertical racks 404; when they are relatively close, the guide column 403 can effectively limit the rear cover, and when they are relatively far away, the lower guide column 403 still maintains support for the rear cover, but the upper guide column 403 is raised to release the limit on the guide column 403.

[0028] Reference Figures 2 to 5 In this embodiment, preferably, the adjustment assembly 2 includes a truncated table 201 fixedly mounted at the center of the platform 1 and a gear 204 fixedly mounted on the outer surface of the crossbar 303. A tooth segment 202 corresponding to the position of the gear 204 is fixedly mounted on the top surface of the truncated table 201. When the crossbar 303 drives the gear 204 to move along the circumferential direction of the platform 1, that is, moves along the circumferential direction of the truncated table 201, the gear 204 can contact the tooth segment 202 to drive the crossbar 303 to rotate 180 degrees. The position corresponding to the tooth segment 202 is the position where the rear cover is flipped 180 degrees, which is the left side of the truncated table 201 in this embodiment.

[0029] Furthermore, the outer surface of the truncated table 201 and the inner wall of the platform 1 are fixedly mounted with an arcuate edge 203 corresponding to the position of the moving component 5, and the arcuate edge 203 has a notch 205 and the notch 205 corresponds to the loading position of the rear cover. At this time, the moving component 5 has not yet contacted the arcuate edge 203, and the moving component 5 will not drive the tooth column 405 to rotate. When the crossbar 303 drives the bracket 401 to rotate, the moving component 5 can rotate synchronously. At this time, the moving component 5 contacts the arcuate edge 203 and drives the tooth column 405 to rotate, so that the two vertical racks 404 drive the two bases 402 to be relatively close, and the rear cover is limited.

[0030] In this embodiment, the gear 204 and the tooth segment 202 are both provided in one and correspond to the position of the truncated table 201. At this time, the bracket 401 close to the truncated table 201 can be rotated through the gear 204 and the cross bar 303 close to the truncated table 201, while the bracket 401 far from the truncated table 201 is driven to rotate by the bracket 401 close to the truncated table 201 and the back cover. Of course, in actual use, the gear 204 and the tooth segment 202 can be provided in two, and the two gears 204 correspond to the two tooth segments 202 one by one, so that the two cross bars 303 can rotate 180 degrees synchronously.

[0031] Reference Figure 2 , Figure 3 and Figure 5 In this embodiment, preferably: the moving component 5 includes a telescopic sleeve 501, one telescopic sleeve 501 is slidably matched with the outer surface of the truncated table 201, and the other telescopic sleeve 501 is slidably matched with the inner wall of the platform 1; correspondingly, the outer surface of the truncated table 201 and the inner wall of the platform 1 are both provided with annular grooves for the sliding placement of the two telescopic sleeves 501.

[0032] Furthermore, a stopper 502 corresponding to the position of the arc-shaped edge 203 is fixedly installed at the end of the telescopic sleeve 501, wherein one stopper 502 corresponds to the arc-shaped edge 203 of the truncated table 201 and abuts against the outer surface of the truncated table 201, and the other stopper 502 corresponds to the arc-shaped edge 203 of the platform 1 and abuts against the inner wall of the platform 1. Here, the telescopic sleeve 501 makes the stopper 502 have a tendency to approach the arc-shaped edge 203, and when the stopper 502 contacts the arc-shaped edge 203, the stopper 502 can move away from the arc-shaped edge 203 under the push of the arc-shaped edge 203.

[0033] The surface of the support rod 502 is fixedly mounted with a ring 503 sleeved outside the cross bar 303, and there is no contact relationship between the ring 503 and the cross bar 303. The end of the sleeve is rotatably mounted with a horizontal rack 504 that is transmission-connected to the tooth column 405, wherein the horizontal rack 504 and the two vertical racks 404 are also in a misaligned state. Correspondingly, the end of the cross bar 303 away from the cantilever 302 is also formed with a side plate 304 that contacts the bracket 401, and the side plate 304 can ensure the contact effect with the bracket 401, and the side plate 304 is used to slide the horizontal rack 504; here, the horizontal rack 504 can slide along the axial direction of the cross bar 303 based on the side plate 304, and the side plate 304 can drive the horizontal rack 504 to rotate along the circumferential direction of the cross bar 303, and the rotational coordination between the horizontal rack 504 and the ring 503 makes the ring 503 unaffected.

[0034] Specifically, the telescopic sleeve 501 includes a sleeve that is slidably matched with the round table 201 or the platform 1. The interior of the sleeve is elastically connected to a telescopic rod through a spring (not shown in the figure). The spring makes the telescopic rod have a tendency to shrink into the sleeve. The end of the telescopic rod away from the sleeve is fixedly connected to the stop rod 502 to drive the stop rod 502 to move accordingly. It can be understood that the structures of the bracket 401, the base 402, the cross bar 303, the ring 503 and the stop rod 502 on both sides are exactly the same, but they are arranged in a symmetrical state.

[0035] When in use, the back cover starts to be loaded from the position of the arc plate notch 205, and falls onto the two side guide columns 403 located below, and is supported by the guide columns 403; then the motor 301 is started to drive the two cross bars 303 to move along the circumferential direction of the platform 1 through the cantilever 302, and the cross bars 303 drive the bracket 401, the base 402 and the back cover to move synchronously through the side plates 304, and the side plates 304 drive the support rod 502 to move along the circumferential direction of the truncated table 201 through the cross rack 504 and the ring 503. At this time, the push rod 502 contacts the outer surface of the arc edge 203 through the notch 205, and the push rod 502 can approach the direction of the bracket 401 and drive the horizontal rack 504 to move synchronously. At this time, the horizontal rack 504 can drive the gear column 405 to rotate, so that the two vertical racks 404 and the two bases 402 are relatively close, and then the guide columns 403 on the upper and lower sides are close to achieve clamping and limiting the back cover. Because the guide columns 403 are elastically arranged with the base 402 through elasticity, squeezing damage to the back cover can be avoided.

[0036] When the cross bar 303 drives the bracket 401 to move to the rear side of the truncated table 201, rapid detection is achieved through the camera detection module on the rear side; then the cantilever 302 drives the cross bar 303 to continue moving, so that the gear 204 contacts the tooth segment 202 and then drives the cross bar 303, the side plate 304 and the bracket 401 to rotate 180 degrees, and the side plate 304 drives the cross rack 504 to move synchronously so that the transmission between the cross rack 504 and the tooth column 405 remains unchanged, and the ring 503 and the push rod 502 maintain their positions unchanged through the telescopic sleeve 501. Then the cross bar 303 drives the bracket 401 to continue to move to the front side of the table 201, and a quick detection can be achieved through the camera detection module on the front side; finally, the cross bar 303 drives the bracket 401 to move to the initial position, and at this time the support rod 502 enters the notch 205 again, which can drive the ring 503 and the horizontal rack 504 to approach the table 201, thereby causing the tooth column 405 to rotate in the opposite direction, so that the two vertical racks 404 and the two bases 402 are relatively far away and reset, and the back cover can be unloaded at this time.

[0037] In this embodiment, the loading and unloading positions are at the same position. In actual application, the size of the notch 205 based on the arc edge 203 can be relatively increased, so that the loading and unloading positions are two positions, which can realize the simultaneous loading and unloading, thereby further improving production efficiency.

[0038] At the same time, the number of crossbars 303 can be increased in groups of two, and the structures such as brackets 401, gears 204, rings 503 and stoppers 502 can be increased accordingly, while the number of arc plates and tooth segments 202 remains unchanged, which can be applied to multiple groups of stoppers 502 and gears 204. It can realize the synchronous processing of multiple back covers, and in the best state, there are five, so that the first back cover is being loaded, the second back cover is being tested on the front side (or back side), the third back cover is being turned over 180 degrees, the fourth back cover is being tested on the back side (or front side), and the fifth back cover is being unloaded.

[0039] In summary, through the coordination of the structures such as the round table 201, the crossbar 303, the bracket 401 and the tooth column 405, when the rear cover is loaded and then moved, it can not only realize the automatic limit of the rear cover to prevent the rear cover from falling off during movement and affecting the detection; it can also drive the rear cover to automatically flip 180 degrees, so as to realize the rapid detection of the front and back of the rear cover; it can also realize the automatic release of the rear cover limit, and then realize the rapid loading and unloading of the rear cover, which can further improve the production efficiency. The overall structure is linked and more functional. There is no need to set cylinders in multiple directions for the limit of each rear cover, nor is there a need to equip the movement of each cylinder with a corresponding CNC program, which can relatively improve the overall production efficiency and reduce the burden of later repair and maintenance, and is more practical.

[0040] Embodiment 2: See also Figures 1 to 8On the basis of the first embodiment, it is considered that when the cross bar 303 drives the base 402 to move along the circumferential direction of the platform 1, the back cover may slide and deviate along the radial direction of the platform 1 due to the centrifugal force; at the same time, due to the possible deviation in the position of the loading material, the subsequent camera detection module cannot accurately correspond to the back cover, thereby affecting the detection process and effect.

[0041] To this end, the horizontal rack 504 and the bracket 401 are improved: in this case, a partition 6 is fixedly installed at the end of the horizontal rack 504 away from the ring 503, and the partition 6 is located at the center of the vertical direction based on the bracket 401, and is located on the side of the vertical rack 404 close to the base 402, and is staggered with the two vertical racks 404. When the horizontal rack 504 moves, it drives the tooth column 405 to rotate on the one hand, and drives the partition 6 to move synchronously on the other hand. At this time, the two partitions 6 can be relatively close to automatically limit the rear cover to the center.

[0042] Furthermore, the partition 6 can be designed as two and overlapped on the left and right, and the two partitions 6 can be elastically connected by a spring (not shown in the figure). At this time, the partition 6 away from the horizontal rack 504 can contact and squeeze the spring before the rear cover, thereby further reducing the damage to the rear cover.

[0043] The partition plate 6 is designed based on the center of the bracket 401 , and can also be offset from the guide pillars 403 on both sides, so that the movement of the partition plate 6 will not interfere with the guide pillars 403 .

[0044] When in use, the automatic limit, automatic release of limit and automatic flipping of the rear cover by 180 degrees can be realized through the structures such as the truncated table 201, the cross bar 303 and the tooth column 405. The working process and effect of this part are the same as those in the first embodiment, and will not be repeated here. The difference is that when the side plate 304 drives the push rod 502 to move along the circumferential direction of the truncated table 201 through the cross rack 504 and the ring 503, the push rod 502 can drive the cross rack 504 to move toward the bracket 401 through the arc edge 203 and the ring 503. At this time, the cross rack 504 drives the tooth column 405 to rotate on the one hand, so that the two bases 402 are relatively close to each other up and down, and on the other hand, drives the partition 6 to move in the direction away from the side plate 304, so that the two partitions 6 are relatively close to each other left and right, so as to realize the comprehensive limit of the rear cover in the up, down, left and right directions.

[0045] Compared with the first embodiment, through the cooperation of the structures such as the horizontal rack 504, the bracket 401 and the partition 6, the horizontal rack 504 can not only drive the tooth column 405 to rotate when moving, so that the two bases 402 are relatively close to each other, but also drive the partition 6 to move so that the two partitions 6 are relatively close to each other, thereby realizing the comprehensive limit of the upper and lower left and right directions of the rear cover, avoiding the sliding deviation of the rear cover caused by centrifugal force; at the same time, it also has an automatic centering effect on the rear cover, ensuring the detection quality of the subsequent camera detection module. The overall design is combined with the movement of the horizontal rack 504, making the horizontal rack 504 more functional, more conducive to detection, and more applicable.

[0046] Embodiment three: See also Figures 1 to 10 On the basis of the second embodiment, considering that the base 402 and the guide column 403 above the bracket 401 are always above the back cover, although the upper and lower limit effects of the back cover are achieved, the back cover may be blocked. On the one hand, it will affect the detection of the camera detection module and cannot achieve comprehensive detection of the front / side of the back cover; on the other hand, it will affect the loading and unloading of the back cover, so that the back cover can only be taken in and placed from both sides of the bracket 401, which has certain usage limitations.

[0047] To this end, the arcuate edge 203, the cantilever 302 and the vertical rack 404 are improved: the vertical rack 404 now includes a vertical section 4041 meshing with the tooth column 405 and a transverse section 4042 fixedly connected to the base 402, the transverse section 4042 is rotatably mounted on the vertical section 4041 through a rotating shaft and a torsion spring (not shown in the figure), the two are in an inverted T-shaped state, and the torsion spring allows the transverse section 4042 to be perpendicular to the vertical section 4041. Because the surface of the bracket 401 restricts the base 402, the base 402 will no longer deflect toward the tooth column 405; when the vertical section 4041 drives the transverse section 4042 and the base 402 to rise, the base 402 can be separated from the surface of the bracket 401, and the rotation restriction on the base 402 can be released at this time.

[0048] In order to realize the rotation of the base 402 driven by the transverse section 4042, an extension rod 305 corresponding to the position of the transverse section 4042 is fixedly installed on the top of the cantilever 302, and the end of the extension rod 305 away from the cantilever 302 is corresponding to the transverse section 4042 up and down. When the transverse section 4042 rises, it can contact the extension rod 305, thereby making the transverse section 4042 rotate based on the vertical section 4041, and driving the base 402 to rotate synchronously.

[0049] In order to achieve the further movement of the vertical section 4041, a groove 206 is jointly provided between one arcuate edge 203 and the truncated cone 201 and between the other arcuate edge 203 and the platform 1. The depth dimension of the groove 206 based on the truncated cone 201 is greater than the depth dimension of the notch 205 based on the truncated cone 201, so that when the support rod 502 passes through the groove 206, the horizontal rack 504 can drive the vertical section 4041 to a relatively farther distance through the gear 204.

[0050] In the above structure, the position of the groove 206 may correspond to the position of the camera detection module, and two grooves may be provided, so that when the rear cover reaches below the camera detection module, the upper base 402 and guide pillar 403 in the bracket 401 may deflect and avoid. Furthermore, the notch 205 may be directly replaced with the groove 206, so that the upper base 402 and guide pillar 403 in the bracket 401 may also deflect and avoid when the material is in the loading and unloading position.

[0051] When in use, the structures such as the truncated table 201, the cross bar 303 and the tooth column 405 can realize automatic limiting, automatic releasing of limiting and automatic flipping 180 degrees of the rear cover; the structures such as the horizontal rack 504, the bracket 401 and the partition 6 can realize comprehensive limiting of the upper, lower, left and right directions of the rear cover. The working process and effect of this part are the same as those in Example 1 and will not be repeated here. The difference is: when the support rod 502 passes through the groove 206 at the initial position and reaches the arc plate, the horizontal rack 504 can drive the tooth column 405 to rotate, thereby achieving comprehensive limiting of the rear cover; when reaching the groove 206 on the front / rear side along the arc edge 203, the support rod 502 will drive the tooth column 405 to rotate in the opposite direction through the horizontal rack 504, thereby driving the vertical section 4041, the horizontal section 4042 and the bracket 401 to rise, so that the horizontal section 4042 contacts the extension rod 305. At this time, the horizontal section 4042 can drive the upper base 402 and the guide column 403 to deflect, thereby avoiding the front / back side of the rear cover.

[0052] Compared with the second embodiment, through the coordination of the vertical section 4041, the horizontal section 4042, the extension rod 305 and the cantilever 302, when the back cover is loaded and unloaded and inspected by the camera detection module, the upper base 402 and the bracket 401 can avoid the back cover based on the deflection of the bracket 401, so that the camera detection module can fully detect the back cover, which can further ensure the overall detection effect; it is also convenient for the back cover to be placed on the lower base 402 and the guide column 403, which can further improve the overall production efficiency. The overall design is combined with the movement of the horizontal rack 504 again, and the horizontal rack 504 makes the reverse movement of the base 402 farther, thereby realizing the deflection avoidance. At the same time, the effective limit of the back cover can still be guaranteed when it is turned over 180 degrees, which will not affect the turning of the back cover and is conducive to detection and loading and unloading, meeting more needs in actual use.
