[0047] In order to make the technical problems, technical schemes and beneficial effects of the utility model to be solved more clear and obvious, the utility model will be further described in detail below in combination with the drawings and examples. It should be understood that the specific examples described herein are only used to explain the utility model and are not used to limit the utility model. Therefore, the feature referred to in the specification is used to explain one of the features of one embodiment of the utility model, and it is not implied that each embodiment of the utility model must have the explained feature. In addition, it should be noted that the specification describes many features. Although certain features can be combined together to show possible system designs, these features can also be used in other combinations that are not explicitly described. Therefore, unless otherwise stated, the explained combination is not intended to be limited.

[0048] The principles and structures of the utility model will be described in detail below in combination with the drawings and examples.

[0049] In some examples, as shown in Figures 1-2 the utility model provides a flip type centering and laminating clamp, comprising:

[0050] The base 10 is provided with a containing groove 101 for placing a mobile phone middle frame; a top cover 40 matched with the top of the base 10 is turned over and closed, the top cover 40 is provided with a containing through hole 401 for placing a front panel or a back cover corresponding to the containing groove 101, a plurality of gap pieces 50 are circumferentially arranged on the side edge of the containing through hole 401 away from the containing groove 101, and the gap pieces 50 are used for making the geometric center of the front panel or the back cover coincide with the geometric center of the mobile phone middle frame.

[0051] It should be noted that the shapes of the containing groove 101 and the containing through hole 401 are preferably rectangular or square.

[0052] In this way, the top cover 40 is first turned over and opened relative to the top of the base 10, and then the mobile phone middle frame is placed in the containing groove 101 in correspondence and accuracy; according to the design gap between the mobile phone middle frame and the front panel or the back cover, the gap pieces 50 with a specific length are arranged in correspondence, the physical limiting is performed through the gap pieces 50, then the top cover 40 is turned over and closed relative to the top of the base 10, and then the front panel or the back cover is placed in the containing through hole 401 in correspondence, so that the geometric center of the front panel or the back cover coincides with the geometric center of the mobile phone middle frame, the alignment accuracy and the gap uniformity between the front panel or the back cover and the mobile phone middle frame are ensured, and the appearance coordination, the visual symmetry and the structural stability of the mobile phone are improved.

[0053] Therefore, compared with the scheme of realizing the front panel or the back cover and the mobile phone middle frame centering and adhering process through the CCD visual automatic equipment or the semi-automatic equipment, the front panel or the back cover is physically limited through the gap pieces 50 in the utility model, so that the geometric center of the front panel or the back cover coincides with the geometric center of the mobile phone middle frame, the front panel or the back cover and the mobile phone middle frame are centered and adhered, and the flip type centering and adhering clamp has the advantages of low cost and easy popularization.

[0054] For the convenience of understanding, the embodiment is exemplified by the central fitting of the middle frame and the back cover of the mobile phone. For example, the length of the back cover is 164.0 mm, the width is 75.0 mm, the length of the middle frame is 164.4 mm, and the width is 75.4 mm. The length of the gap piece 50 extending into the accommodating through hole 401 is 0.2 mm. Then, the back cover is placed in the accommodating through hole 401. In this way, the back cover is fitted through the gap piece 50 on both sides along the X-axis direction and the Y-axis direction, so that the geometric center of the back cover coincides with the geometric center of the middle frame of the mobile phone, thereby completing the central fitting of the back cover and the middle frame of the mobile phone. If the gap piece 50 is not added around the accommodating through hole 401, the back cover will be fitted on one side of the accommodating through hole 401 along the X-axis direction. At this time, the gap between the back cover and the accommodating through hole 401 on one side along the X-axis direction is 0, and the gap between the back cover and the accommodating through hole 401 on the other side along the X-axis direction is 0.4 mm. If the gap specification is 0.2 mm, the gap of 0.4 mm is out of specification, which leads to the failure of the central fitting of the back cover and the middle frame of the mobile phone.

[0055] In some embodiments, in order to ensure that the flip central fitting clamp has a foolproof function, as shown in Figure 2 The bottom of the accommodating groove 101 is respectively provided with an accommodating groove 102 for placing a first sensing foolproof device 20 and a second sensing foolproof device 30, and the first sensing foolproof device 20 and the second sensing foolproof device 30 do not extend from the bottom of the accommodating groove 101.

[0056] It should be noted that the first sensing foolproof device 20 and the second sensing foolproof device 30 are both provided, and the first sensing foolproof device 20 is arranged in the middle of one side of the accommodating groove 101 along the X-axis direction, and the second sensing foolproof device 30 is arranged in the middle of one side of the accommodating groove 101 along the Y-axis direction.

[0057] In this way, when the middle frame of the mobile phone is placed in the accommodating groove 101, the first sensing foolproof device 20 and the second sensing foolproof device 30 detect whether the middle frame of the mobile phone is accurately placed, thereby performing foolproof processing through the first sensing foolproof device 20 and the second sensing foolproof device 30.

[0058] In some embodiments, as shown in Figure 4 The flip central fitting clamp further includes a base 80, and the base 80 is composed of a box body 801 and a cover plate 802 which is reversibly combined with the box body 801. The middle of the top of the cover plate 802 is provided with the base 10. The inside of the box body 801 is provided with a control unit, a wire and corresponding electrical elements, which are not limited here. The box body 801 is provided with a handle 803 on both sides along the X-axis direction, so that the user can hold the handle 803 with both hands to move, thereby improving the flexibility of the flip central fitting clamp. Figure 6As shown, the front side of the box 801 (which is equivalent to one side of the box 801 along the Y-axis direction thereof) is provided with an emergency stop button 90 and a foolproof alarm device 100 electrically connected with the control unit; the back side of the box 801 (which is equivalent to the other side of the box 801 along the Y-axis direction thereof) is provided with a wiring port 110 and a start button 120 electrically connected with the control unit. The wiring port 110 includes a power supply interface and a grounding interface, etc., which are not limited herein.

[0059] In some embodiments, in order to ensure that the geometric center of the front panel or the back cover accommodated in the accommodating through hole 401 can be more accurately overlapped with the geometric center of the mobile phone middle frame in the accommodating groove 101, and prevent installation deviation, as shown in Figure 2 As shown, the accommodating through hole 401 is rectangular, and at least one pair of gap pieces 50 is symmetrically or asymmetrically distributed at the side edge of the accommodating through hole 401 away from the accommodating groove 101.

[0060] Specifically, a pair of gap pieces 50 is symmetrically arranged at the middle part of the two sides of the top of the accommodating through hole 401 (which is equivalent to the side of the accommodating through hole 401 away from the accommodating groove 101, the same below) along the X-axis direction, and two pairs of gap pieces 50 are symmetrically arranged at the two sides of the top of the accommodating through hole 401 along the Y-axis direction.

[0061] It should be noted that the material of the gap piece 50 is preferably silicon steel.

[0062] In some embodiments, in order to ensure that the gap piece 50 can be replaced according to the size of the mobile phone middle frame, the front panel and the back cover in the bonding process, and improve flexibility, the connection between the gap piece 50 and the edge of the accommodating through hole 401 is detachable.

[0063] Further, in order to reduce the wear of the gap piece 50, as shown in Figure 3 and 5 As shown, a protective pressing plate 60 is matched arranged at the top of the gap piece 50, and the protective pressing plate 60 is detachably connected with the corresponding gap piece 50.

[0064] It should be noted that the gap piece 50 and the protective pressing plate 60 are both vertically penetrated by at least one threaded hole, and then the screws are sequentially passed through the protective pressing plate 60 and the corresponding gap piece 50 and then screwed with the top cover 40.

[0065] In some embodiments, the first sensing foolproof device 20 is a Hall sensor, and the first sensing foolproof device 20 is used to detect whether the magnetic component in the mobile phone middle frame is placed correspondingly;

[0066] The second sensing foolproof device 30 is a photoelectric sensor, and the photoelectric sensor is used to detect whether the mobile phone middle frame is placed in the accommodating groove 101.

[0067] It should be noted that the first sensing fool-proof device 20 and the second sensing fool-proof device 30 are electrically connected with the control unit. The magnetic component in the embodiment is preferably an earpiece, and of course the magnetic component is not limited to the earpiece, but can be selected as other magnetic components in the middle frame of the mobile phone according to the actual situation, which is not limited here.

[0068] It can be understood that the Hall sensor judges whether the position of the middle frame of the mobile phone is accurately placed based on the Hall effect by detecting the change of the magnetic field. When the middle frame of the mobile phone is accurately placed, the magnetic component of the earpiece in the middle frame of the mobile phone will trigger the Hall sensor to generate a Hall voltage and output a first electric signal to the control unit. The photoelectric sensor will output a second electric signal to the control unit as long as it is blocked by the middle frame of the mobile phone. Then, the control unit judges whether the middle frame of the mobile phone is accurately placed in the accommodating groove 101 according to the received first electric signal and second electric signal. Only when the control unit receives the first electric signal and the second electric signal, it can be determined that the middle frame of the mobile phone is accurately placed in the accommodating groove 101. If the control unit only receives the first electric signal or the second electric signal, it is determined that the middle frame of the mobile phone is not accurately placed in the accommodating groove 101. At this time, the control unit controls the fool-proof alarm device 100 to emit a buzzing sound and flash a red light to remind the user to adjust.

[0069] In some embodiments, in order to ensure that the middle frame of the mobile phone can be more accurately placed in the accommodating groove 101, as shown in Figure 1 and 3 , the accommodating groove 101 is provided with at least one clamping device 70 along the X-axis direction and the Y-axis direction, and the clamping device 70 is used for fixing the middle frame of the mobile phone.

[0070] Specifically, the clamping device 70 includes a pushing driving assembly 701 and a clamping block 702.

[0071] The accommodating groove 101 is recessed outward to form a pushing space 103 along at least one side of the X-axis direction and at least one side of the Y-axis direction, and the pushing space 103 extends to the accommodating groove 101.

[0072] The pushing driving assembly 701 is arranged in the base 10 or the cover plate 802 corresponding to the pushing space 103, the pushing end of the pushing driving assembly 701 is connected with the clamping block 702, and the clamping block 702 can move towards or away from the center of the accommodating groove 101 in the pushing space 103.

[0073] It should be noted that the accommodation groove 101 is provided with a clamping device 70 on the side thereof along the X-axis direction and away from the first sensing foolproof device 20, and on the side thereof along the Y-axis direction and away from the second sensing foolproof device 30. When the pushing driving assembly 701 is not in operation, the clamping block 702 in the pushing space 103 does not extend into the accommodation groove 101, so as not to hinder the placement of the middle frame of the mobile phone. The pushing driving assembly 701 is preferably a pushing motor, and is electrically connected with the control unit.

[0074] Thus, when the control unit receives the first electric signal and the second electric signal, the mobile phone middle frame may still be partially offset at this time, and the control unit will then start the pushing driving assembly 701 to drive the clamping block 702 to move towards the center of the accommodation groove 101, until the side of the mobile phone middle frame away from the clamping block 702 is in contact with the accommodation groove 101, and then the control unit will turn off the pushing driving assembly 701, so as to ensure that the mobile phone middle frame can be more accurately placed in the accommodation groove 101, and also to play a certain limiting role to prevent the mobile phone middle frame from shaking during the contact process.

[0075] In some embodiments, in order to ensure that the front panel or the back cover does not deviate during the centering contact with the mobile phone middle frame, so as to ensure that the geometric center of the front panel or the back cover coincides with the geometric center of the mobile phone middle frame, as shown in Figure 1 The top of the base 10 is provided with at least one positioning groove 104 along the accommodation groove 101;

[0076] The side of the top cover 40 in the closing direction towards the accommodation groove 101 is provided with a positioning block 402 corresponding to the positioning groove 104, and the positioning block 402 can be matched and inserted into the corresponding positioning groove 104.

[0077] In some embodiments, in order to further ensure that the front panel or the back cover does not deviate during the centering contact with the mobile phone middle frame, so as to ensure that the geometric center of the front panel or the back cover coincides with the geometric center of the mobile phone middle frame, as shown in Figure 1 The top of the base 10 is provided with at least one first connecting block 105 along the accommodation groove 101;

[0078] The side of the top cover 40 in the closing direction towards the accommodation groove 101 is provided with a second connecting block 403 corresponding to the first connecting block 105, and the second connecting block 403 can be magnetically connected or clamped with the corresponding first connecting block 105.

[0079] Of course, the connection between the first connecting block 105 and the second connecting block 403 in the present embodiment is preferably a magnetic connection.

[0080] In some embodiments, as shown in Figure 1As shown, the edge of the top of the base 10 is outwardly through formed at least one clamping groove 106;

[0081] As shown, when the top cover 40 and the base 10 match cover, the top cover 40 covers on the clamping groove 106. Figure 4

[0082] In this way, when the mobile phone middle frame and the front panel or the back cover complete the centering process, the user uses the finger or the clamping tool to stretch into the clamping groove 106, and then pulls up the top cover 40, so as to open the top cover 40 relative to the base 10, so as to take out the product which completes the centering process, and then accurately place a new mobile phone middle frame in the containing groove 101, and then carry out the centering process again.

[0083] Obviously, the above described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. The preferred embodiments of the present application are given in the drawings, but do not limit the patent scope of the present application. The present application can be realized in many different forms, and conversely, the purpose of providing these embodiments is to make the disclosure of the present application more thorough and comprehensive. Although the present application has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions recorded in the foregoing specific embodiments, or equivalently replace some technical features. Any equivalent structure made by using the content of the present application specification and drawings, directly or indirectly used in other related technical fields, is also within the patent protection scope of the present application.​
