It should also be understood that terms defined in a general dictionary, such as those, should be interpreted as having meanings consistent with their meanings in the context of the relevant art, and should not be interpreted in an idealized or overly formal sense, unless specifically defined as such herein.

[0028] Technologies, methods, and devices known to those of ordinary skill in the relevant fields may not be discussed in detail, but where appropriate, the technologies, methods, and devices should be regarded as part of the specification.

[0029] As Figures 1 to 3 shown, the present disclosure provides a glass cover plate clamping device, including: a platform 4 for placing a glass cover plate; a positioning assembly 1 including two positioning blocks 101 distributed along a first direction; a guiding assembly 2 through which the positioning assembly 1 is selectively positioned relative to the platform 4 along a second direction and a third direction, the first direction, the second direction, and the third direction being perpendicular to each other pairwise; and a clamping assembly 3 including two clamping blocks 301 that can be respectively placed on the two positioning blocks 101 and positioned along the second direction and the third direction; wherein the two clamping blocks 301 can relatively move along the first direction on the two positioning blocks 101 to clamp the glass cover plate.

[0030] Specifically, when using the glass cover plate clamping device, the staff stacks the glass cover plates between two positioning blocks 101 distributed along the first direction on the platform 4, and uses the guiding component 2 to guide the two positioning blocks 101 to move in the second direction and the third direction to calibrate the relative position between the positioning blocks 101 and the glass cover plates, so that when the two clamping blocks 301 are respectively placed on the two positioning blocks 101, the connection line of the two clamping blocks 301 can coincide with the designated position of the glass cover plate. After the guiding component 2 guides the positioning component 1 to complete the positioning, the staff then places the two clamping blocks 301 for clamping the glass cover plates on the two positioning blocks 101 respectively. At this time, the connection line of the two clamping blocks 301 coincides with the designated position of the glass cover plate. The staff operates the two clamping blocks 301 to move relatively along the first direction to precisely clamp the stacked glass cover plates. For glass cover plates of the same model but different batches, it effectively ensures that the relative position between the clamping component 3 and the glass cover plates remains unchanged each time of clamping, eliminates the deviation during clamping, is conducive to the worker accurately placing the glass cover plates of different batches at the designated position of the edge polishing machine for polishing, avoids the problems of time-consuming calibration and low precision in the subsequent production process of the glass cover plates, reduces the possibility of large differences in the same group of processing or repeated processing, and effectively improves the production efficiency.

[0031] It can be seen that the positioning component 1 can achieve pre-positioning with the platform 4 by means of the guiding component 2, that is, to achieve the relative positioning between the positioning component 1 and the glass cover plate to be placed, and the clamping component 3 can be relatively positioned with the positioning component 1, so as to achieve the relative positioning between the clamping component 3 and the glass cover plate, so that the clamping component 3 clamps the glass cover plate at a specific relative position.

[0032] In some embodiments, in order to keep the stacked glass cover plates stable when clamped by the clamping component 3, when using the guiding component 2 to guide the positioning component 1 for pre-positioning, the two positioning blocks 101 are guided to the center line of the glass cover plate. In other embodiments, for the convenience of the clamping component 3 to clamp the glass cover plate, it can also be pre-positioned to other designated positions of the glass cover plate.

[0033] In addition, the placement time of the clamping component 3 has nothing to do with the process of the guiding component 2 guiding the positioning component 1 for pre-positioning. The staff can place the clamping component 3 on the positioning component 1 before pre-positioning, which can more conveniently observe whether the clamping component 3 reaches the designated position, or can place the clamping component 3 on the positioning component 1 after pre-positioning to avoid the occlusion of the clamping component 3 during the pre-positioning process, which is convenient for the staff to perform the pre-positioning operation, or can place the clamping component 3 during the pre-positioning process. For example, after roughly completing the positioning and placing the clamping component 3 on the positioning component 1, then use the guiding component 2 for fine-tuning.

[0034] In some embodiments, a calibration block is provided on the platform 4 that can extend relative to the platform 4 to stop the positioning block 101. Specifically, for several common types of glass covers in production, by setting calibration blocks at positions corresponding to these types of glass covers on the platform 4, when producing a specific type of glass cover, the calibration block can be extended to stop the positioning block 101 to achieve faster pre-positioning. In other embodiments, the calibration block can also be in the form of calibration marks or calibration scales, etc. Similarly, the components that perform the calibration function can also be provided on the guiding component 2 or other components of the glass cover clamping device.

[0035] As Figure 1 and Figure 2 shown, in some embodiments, the guiding component 2 includes a first guide rail 201 connected to the platform 4 and extending in the second direction and a second guide rail 202 extending in the third direction. The second guide rail 202 is slidably disposed on the first guide rail 201, and the positioning component 1 is slidably disposed on the second guide rail 202.

[0036] Specifically, the staff adjusts the position of the second guide rail 202 on the first guide rail 201 to guide the positioning component 1 to move in the second direction, and adjusts the position of the positioning component 1 on the second guide rail 202 to guide the positioning component 1 to move in the third direction, so that the positioning component 1 can achieve selective positioning in the second direction and the third direction.

[0037] In some embodiments, the guiding component 2 can also include ball screws respectively disposed in the second direction and the third direction, at least including support seats placed in two directions, screws disposed on the support seats, nuts sleeved on the screws, and drivers, and the positioning component 1 is connected to the nuts. Utilizing the advantages of high precision and high efficiency of the ball screws to improve the positioning accuracy and positioning efficiency of the device.

[0038] As Figure 1 and Figure 2 shown, in some embodiments, a first slider 203 for carrying the second guide rail 202 is provided on the first guide rail 201, and a second slider 204 for carrying the positioning component 1 is provided on the second guide rail 202.

[0039] Specifically, the staff adjusts the position of the first slider 203 on the first guide rail 201 to guide the second guide rail 202 connected thereto and the positioning component 1 connected to the second guide rail 202 to move simultaneously in the second direction, and adjusts the position of the second slider 204 on the second guide rail 202 to guide the positioning component 1 connected thereto to move in the third direction, so that the positioning component 1 can achieve selective positioning in the second direction and the third direction.

[0040] In some embodiments, the guiding assembly 2 further includes a scale member for improving the guiding accuracy. The scale member may be a scale provided on the first guide rail 201 and the second guide rail 202, facilitating the staff to control the moving distances of the first slider 203 and the second slider 204. The scale member may also be a grating scale, including a scale grating and a reading head respectively provided on the first guide rail 201 and the first slider 203, and on the second guide rail 202 and the second slider 204. Relying on the advantages of high measurement accuracy and small repeated error of the grating scale, it ensures the coincidence degree between the positioning block 101 and the center of the glass cover plate and the accuracy of repeated positioning, and improves the accuracy and stability during the use of the device.

[0041] As Figure 1 and Figure 2 shown, in some embodiments, the guiding assembly 2 includes a first driving member 205 provided on the first guide rail 201 and a second driving member 206 provided on the second guide rail 202.

[0042] Specifically, the first driving member 205 and the second driving member 206 are respectively used to drive the first slider 203 and the second slider 204 to move along the first guide rail 201 and the second guide rail 202, so as to improve the pre-positioning efficiency and reduce the manual workload. Here, the driving member may be a conventional driving member such as an electric motor, a cylinder or a hydraulic cylinder.

[0043] In some embodiments, the guiding assembly 2 includes a control member, which is used to receive the motion state information (such as position, speed and acceleration, etc.) of the first slider 203 and the second slider 204, and output signals to the first driving member 205 and the second driving member 206 to adjust the motion state of the sliders, so as to achieve precise positioning and speed control, and more efficiently and stably guide the positioning block 101 to position the glass cover plate. Here, the control member may be a simple relay, or a complex PLC programmable logic controller or a computer control system and other control members that can achieve the above effects.

[0044] As Figure 1 shown, in some embodiments, one positioning block 101 of the positioning assembly 1 is connected to the second slider 204 located on the second guide rail 202 through an intermediate connecting block 6. An intermediate connecting block 6 is also provided on the other positioning block 101 of the positioning assembly 1. When the operation space of the device is limited, it is convenient to install the guiding assembly 2 on the other positioning block 101 of the positioning assembly 1. At the same time, the first guide rail 201 and the second guide rail 202 are detachably connected through a connecting plate 5. The assembled design makes the device easy to disassemble and maintain, and can also adjust the installation position to adapt to different working spaces, improving the stability and applicability of the device.

[0045] As Figure 1 and Figure 2As shown, in some embodiments, the positioning component 1 includes a connecting frame 102 for connecting two positioning blocks 101. Specifically, to keep the connection line of the two positioning blocks 101 always parallel to the first direction, the two positioning blocks 101 are respectively fixedly installed on the connecting frame 102. The connecting frame 102 includes a connecting main rod parallel to the first direction and two connecting secondary rods arranged on the connecting main rod and parallel to each other. The two positioning blocks 101 are respectively installed at the same positions on the two connecting secondary rods to ensure that during the movement of the positioning component 1, the connection line of the two positioning blocks 101 can always be parallel to the connecting main rod, that is, parallel to the first direction.

[0046] As Figure 1 , Figure 2 and Figure 3 shown, in some embodiments, a groove 103 along the first direction is provided on the positioning block 101, and a protrusion 302 capable of cooperating with the groove 103 to enable the clamping block 301 to move along the first direction is provided on the clamping block 301.

[0047] Specifically, taking the glass cover clamping device placed horizontally, the second direction being the vertical direction, and the first and third directions being two mutually perpendicular directions on the horizontal plane as an example. The groove 103 opens upward, so that the protrusion 302 of the clamping block 301 can be placed into the groove 103 along the vertical direction. At the same time, the setting of the protrusion 302 increases the contact area of the clamping block 301 when clamping the glass cover, which is beneficial to enhancing the stability during clamping.

[0048] In some embodiments, along the vertical direction, the depth of the groove 103 is close to the height of the positioning block 101 and the size of the protrusion 302 is adapted to the groove 103. When the stacking height of the glass covers is insufficient and the part to be clamped approaches the platform 4, the clamping component 3 can rely on the protrusion 302 to clamp the glass cover, avoiding the situation where the glass cover cannot be clamped due to insufficient stacking height.

[0049] As Figure 1 , Figure 2 and Figure 3 shown, in some embodiments, the clamping component 3 includes a cylinder slide rail 303, a slide table 304, and a guide rod 305 connecting the cylinder slide rail 303 and the slide table 304. The two clamping blocks 301 are respectively arranged on the cylinder slide rail 303 and the slide table 304.

[0050] Specifically, when the clamping assembly 3 is placed on the positioning assembly 1, the cylinder slide rail 303, the slide table 304, and the guide rod 305 are all arranged and moved along the first direction to achieve the relative movement of the two clamping blocks 301 along the first direction. At the same time, the cylinder slide rail 303 is equipped with an electric valve and a pressure regulating valve. The staff controls the clamping action of the two clamping blocks 301 along the first direction through the electric valve, and then controls the clamping force of the clamping assembly 3 on the glass cover plate through the pressure regulating valve. In actual work, the clamping force of the clamping assembly 3 is adjusted through the pressure regulating valve to be consistent with the clamping force of the edge polishing machine used for subsequent arc edge polishing on the glass cover plate, preventing the stacked glass cover plates from being misaligned due to the change in the clamping force before polishing, thereby avoiding the problem of large differences in the processing of the same group. When facing different operation processes, the pressure regulating valve can be used to adjust the clamping force, improving the adaptability of the device to different operation processes.

[0051] As Figure 1 , Figure 2 and Figure 3 shown, in some embodiments, the clamping assembly 3 further includes a bottom plate 306 disposed on the cylinder slide rail 303, and a fixture handle 307 is installed on the bottom plate 306. Specifically, as Figure 1 shown, when the clamping assembly 3 is placed on the positioning assembly 1, the fixture handle 307 is placed on the top of the bottom plate 306, facilitating the staff to pick up the clamped glass cover plate in the vertical direction. In other embodiments, the fixture handle 307 can also be set at other positions on the clamping assembly 3 that are convenient for the staff to grasp according to the actual situation.

[0052] As Figure 1 and Figure 2 shown, in some embodiments, the platform 4 includes a platform bottom plate 401 for placing the glass cover plate and a platform side plate 402 for stopping the glass cover plate, and both the platform bottom plate 401 and the platform side plate 402 are parallel to the first direction.

[0053] Specifically, to facilitate the neat placement of multiple glass cover plates on the platform 4, the platform side plate 402 is vertically disposed on one side of the platform bottom plate 401, so that the two positioning blocks 101, the platform bottom plate 401, and the platform side plate 402 form a cover plate positioning space. During actual operation, the glass cover plate is placed on the platform bottom plate 401 and located between the two positioning blocks 101. One end of multiple glass cover plates abuts against the platform side plate 402 at the same time, making the edges of the multiple glass cover plates aligned after overlapping, facilitating the next polishing operation.

[0054] As Figure 1 and Figure 2As shown, in some embodiments, a plurality of universal support feet 403 are installed at the bottom of the platform base plate 401. Specifically, in actual use, the plurality of universal support feet 403 provided at the bottom are used to maintain the level of the platform base plate 401 to ensure the stability of the stacked glass cover plates. In other embodiments, the platform 4 may also be provided with a horizontal bubble to monitor the levelness of the platform base plate 401.
