Description

Technical Field

[0001] This invention belongs to the field of mobile phone mid-plate processing, and specifically relates to a mobile phone mid-plate mounting and dismounting mechanism. Background Technology

[0002] In recent years, due to the rapid pace of mobile phone product upgrades and the huge demand for mobile phones, the production efficiency of the mobile phone manufacturing industry has had to be greatly improved, which in turn has led to a significant increase in the production of mobile phone parts.

[0003] During the manufacturing process of mobile phone mid-plates, the surface of the mid-plates needs to be treated in an anodizing bath. Currently, the main method is to suspend the mid-plates in a sub-hanger and then enter the anodizing bath for treatment.

[0004] Currently, the disassembly and assembly of the mobile phone mid-plate and sub-mount are mainly carried out manually or by disassembly and assembly mechanisms. However, when using manual operation, chemical residue remains on the surface of the mobile phone mid-plate after it is processed in the anode pool. This chemical residue is corrosive and can be harmful to the human body. While using disassembly and assembly mechanisms can effectively avoid the harm caused by residual chemical residue, the position of the mobile phone mid-plate often deviates before and after disassembly and assembly on the sub-mount. The disassembly and assembly mechanisms have difficulty accommodating this error, resulting in low disassembly and assembly efficiency and failing to meet production requirements. Summary of the Invention

[0005] In order to solve the problems existing in the prior art, the present invention aims to provide a mobile phone mid-board mounting and dismounting mechanism, so as to realize automatic mounting and dismounting between the mobile phone mid-board and the sub-mount, while reducing the deviation between the two and improving the mounting and dismounting efficiency.

[0006] To achieve the above-mentioned technical objectives and effects, the present invention is implemented through the following technical solution:

[0007] A mobile phone mid-plate mounting and dismounting mechanism includes a support plate and a fixed plate mounted above the support plate via a support column. The support plate is provided with a support module for supporting a sub-mount and driving the sub-mount to move back and forth. The support module is provided with a sub-mount limiting module for limiting the sub-mount mounted on the support module. Above the support module are a pressing module for pressing down the sub-mount after the upper limit of the support module is completed, and a spring lifting module for lifting the spring on the sub-mount. The pressing module and the spring lifting module are mounted on the fixed plate. The support module is also provided with a mid-plate guiding module for guiding the mobile phone mid-plate placed inside the sub-mount.

[0008] Furthermore, the support module includes a support plate, and the lower end of the support plate is provided with a front and rear transfer cylinder and a support linear guide rail. The front and rear transfer cylinder and the support linear guide rail are respectively fixed on the bearing plate by corresponding support seats.

[0009] Furthermore, the sub-hanging fixture limiting module includes a sub-hanging fixture support base, on which at least one set of sub-hanging fixture positioning cylinders are mounted, and a limiting groove is formed at the upper end of the sub-hanging fixture support base.

[0010] Furthermore, the pressing module includes a pressing cylinder and a pressing limit block; the pressing cylinder is vertically downwardly mounted on the fixed plate, and the pressing limit block is mounted at the front end of the piston rod of the pressing cylinder, while the pressing limit block is connected to the fixed plate through a pressing guide post.

[0011] Furthermore, the spring lifting module includes a connecting frame, with a lead screw screwed onto the upper end of the connecting frame. The lead screw is connected to the output shaft of a motor via a coupling. The motor is fixed to the fixed plate via a motor bracket. The connecting frame is connected to the fixed plate via a lifting guide column. A spring lifting hook is provided at the lower end of the connecting frame.

[0012] Furthermore, the middle plate guiding module consists of a middle plate sidewall guiding component, a middle plate front end guiding component, and a middle plate rear end guiding component.

[0013] Furthermore, the middle plate sidewall guiding assembly includes a sidewall guiding carrier plate. The lower end of the sidewall guiding carrier plate is connected to the support plate through a sidewall guiding linear guide rail. A guiding element is provided on the upper end surface of the sidewall guiding carrier plate. The sidewall of the sidewall guiding carrier plate is connected to the piston rod of the sidewall guiding cylinder through a sidewall guiding connecting block.

[0014] Furthermore, the front end guide assembly of the middle plate includes a front end guide plate, the lower end face of the front end guide plate is provided with a guide linear guide rail, the upper end face of the front end guide plate is provided with a guide post, and one side of the front end guide plate is connected to the piston rod of a front end guide cylinder through a front end guide connecting block.

[0015] Furthermore, the middle plate rear end guide assembly includes a rear end guide carrier plate, which is disposed within the support plate and can slide within the support plate. A guide block is provided on the upper end surface of the rear end guide carrier plate, and one side of the rear end guide carrier plate is connected to the piston rod of a rear end guide cylinder through a rear end guide connecting plate.

[0016] Furthermore, it also includes a detection sensor for detecting whether the mobile phone midplate is inside the sub-mount.

[0017] The beneficial effects of this invention are as follows:

[0018] This invention enables fully automated assembly and disassembly of the mobile phone midplate on the sub-mount, without the need for manual intervention. This avoids contact between the operator and the mobile phone midplate and sub-mount, and prevents harm to the operator from residual chemicals.

[0019] The invention effectively reduces the deviation of the mobile phone midplate in the sub-mount by setting a sub-mount limiting module, a pressing module and a midplate guiding module inside, thereby improving the disassembly and assembly efficiency.

[0020] The sub-hanger limiting module and the support module in this invention are connected by an adjustable elongated hole and a limiting post is set in the pressing module.

[0034] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0035] It should be noted that all directional indicators (such as up, down, left, right, front, back, upper end, lower end, top, bottom, etc.) in the embodiments of the present invention are only used to explain the relative positional relationship and movement of each component in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indicator will also change accordingly.

[0036] See Figure 1As shown, a mobile phone mid-plate mounting and dismounting mechanism includes a support plate 1 and a fixing plate 2 mounted above the support plate 1 via a support column 3. The support plate 1 is provided with a support module 4 for supporting a sub-mount 9 and driving the sub-mount 9 to move back and forth. The support module 4 is provided with a sub-mount limiting module 5 for limiting the sub-mount 9 mounted on the support module 4. Above the support module 4 are a pressing module 6 for pressing down the sub-mount 9 after the upper limit of the support module 4 is completed, and a spring lifting module 7 for lifting the springs on the sub-mount 9. The pressing module 6 and the spring lifting module 7 are mounted on the fixing plate 2. The support module 4 is also provided with a mid-plate guiding module, which guides the mobile phone mid-plate 10 placed inside the sub-mount 9.

[0037] Among them, see Figure 2 As shown, in this embodiment, the support module 4 includes a support plate 41. A front-to-back transfer cylinder 42 is provided in the middle of the lower end face of the support plate 41. A support linear guide rail 43 is provided on the left and right sides of the lower end face of the support plate 41. The front-to-back transfer cylinder 42 and the support linear guide rail 43 are respectively fixed on the bearing plate 1 by corresponding support seats. During operation, the front-to-back transfer cylinder 42 drives the support plate 41 to move back and forth along the support linear guide rail 43.

[0038] See Figure 3 As shown, in this embodiment, the sub-hanging fixture limiting module 5 includes a sub-hanging fixture support base 51. Two sets of sub-hanging fixture positioning cylinders 52 are mounted on the sub-hanging fixture support base 51, but this is not limited to two sets; other numbers of sets can also be used, such as one or more sets, as long as the requirements are met. A limiting groove 511 is formed at the upper end of the sub-hanging fixture support base 51. (Continue to see...) Figure 3 As shown, during installation, a set of sub-hanging fixture support seats 51 are respectively set on the left and right sides of the support plate 41. The two sets of sub-hanging fixture support seats 51 are arranged opposite each other. At this time, the limiting groove 511 is located at the connection between the opposite surface of the sub-hanging fixture support seat 51 and its upper end surface. The sub-hanging fixture positioning cylinder 52 is installed on one of the sub-hanging fixture support seats 51. The sub-hanging fixture positioning cylinder 52 is in a horizontal state and inward. That is, when the sub-hanging fixture positioning cylinder 52 is working, the piston rod extends horizontally inward and can hold the sub-hanging fixture 9. In addition, in this embodiment, in order to facilitate the adjustment of the distance between the two sets of sub-hanging fixture support seats 51 arranged opposite each other, the hole on one set of sub-hanging fixture support seats 51 that connects to the support plate 41 is an oblong hole.

[0039] See Figure 4As shown, in this embodiment, the sub-hanger 9 includes a sub-hanger upper crossbar 91 and a sub-hanger support rod 92 disposed at the lower end of the sub-hanger upper crossbar 91. The lower end of the sub-hanger support rod 92 is provided with a middle plate support 93 for supporting the mobile phone middle plate 10. The upper end of the sub-hanger is provided with a spring piece 94 for pressing the mobile phone middle plate 10. The middle plate support 93 is L-shaped. The horizontal connecting plate is connected to the sub-hanger support rod 92, and the vertical connecting plate and the sub-hanger support rod 92 form a receiving groove. In this embodiment, a total of 10 sets of the sub-hanger support rods 92 are provided, that is, 10 sets of mobile phone middle plates 10 can be placed at a time. The 10 sets of the sub-hanger support rods 92 are connected by a sub-hanger lower crossbar 95 to improve the connection strength. During installation, the two ends of the sub-hanger upper crossbar 91 are installed in the limiting groove 511, the sub-hanger support rod 92 is supported on the support plate 41, and the sub-hanger lower crossbar 95 sinks into the support plate 41.

[0040] It should be noted that, see Figure 5 As shown, when both the middle plate support 93 and the spring piece 94 are located on the left side of the sub-hanging support rod 92, after the sub-hanging fixture 9 is installed into the support module 4, the sub-hanging fixture positioning cylinder 52 is located on the sub-hanging fixture support seat 51 on the left side, maintaining the same installation direction. This allows the sub-hanging fixture positioning cylinder 52 to extend and press against the sub-hanging support rod 92.

[0041] See Figure 6 As shown, in this embodiment, the pressing module 6 includes a pressing cylinder 61 and a pressing limiting block 62. The pressing cylinder 61 is vertically downwardly disposed on the upper end surface of the fixed plate 2. After the piston rod of the pressing cylinder 61 passes through the lower end surface of the fixed plate 2, the pressing limiting block 62 is disposed at the front end of the piston rod of the pressing cylinder 61. The pressing limiting block 62 is connected to the fixed plate 2 through a pressing guide post 63. In this embodiment, a total of 4 sets of pressing guide posts 63 are provided, evenly distributed on the pressing limiting block 62, and the lower end is fixedly connected to the pressing limiting block 62. The upper end of the pressing guide post 63 passes through the fixed plate 2 through a corresponding linear bearing. The main function of the pressing guide post 63 is to guide the pressing limiting block 62 to move up and down and prevent lateral deviation. In addition, a limiting post 14 is provided on the lower end surface of the fixed plate 2 to limit the upward lifting height of the pressing limiting block 62.

[0042] See Figure 7As shown, in this embodiment, the spring lifting module 7 includes a connecting frame 71. A vertically upward lead screw 72 is screwed onto the upper end of the connecting frame 71. After the upper end of the lead screw 72 passes through the upper end face of the fixed plate 2, the lead screw 72 is connected to the output shaft of a motor 74 through a coupling 73. The motor 74 is fixed on the fixed plate 2 through a motor bracket 75. The motor 74 is a servo motor. The connecting frame 71 is connected to the fixed plate 2 through lifting guide columns 76. There are four sets of lifting guide columns 76, which are evenly distributed on the connecting frame 71 and are fixedly connected to the connecting frame 71 at their lower ends. The upper ends of the lifting guide columns 76 pass through the fixed plate 2 through corresponding linear bearings. The main function of the lifting guide columns 76 is to guide the connecting frame 71 to move up and down and prevent lateral deviation. The lower end of the connecting frame 71 is provided with a spring lifting hook 77, which corresponds one-to-one with the spring 94.

[0043] Furthermore, the middle plate guiding module consists of a middle plate sidewall guiding component 8, a middle plate front end guiding component 11, and a middle plate rear end guiding component 12.

[0044] See Figure 8 As shown, in this embodiment, the middle plate limiting module 8 includes a side wall guiding plate 81. The lower end face of the side wall guiding plate 81 is connected to the support plate 41 on the left and right sides through side wall guiding linear guide rails 82. The upper end face of the side wall guiding plate 81 is provided with a guiding member 83. The guiding member 83 corresponds one-to-one with the middle plate 10 of the mobile phone in the sub-hanger 9. The side wall of the side wall guiding plate 81 is connected to the piston rod of the side wall guiding cylinder 85 through a side wall guiding connecting block 84. The side wall guiding cylinder 85 is fixed on the support plate 41 through a corresponding support seat. During operation, the side wall guiding plate 8 drives the guiding member 83 to move back and forth along the side wall guiding linear guide rail 82.

[0045] In this embodiment, see below. Figure 8 As shown, the guide member 83 is U-shaped and has an outwardly flared C-angle at the opening. During installation, the opening of the guide member 83 faces the mobile phone middle plate 10 in the sub-hanger 9 to guide the corresponding mobile phone middle plate 10 and prevent the mobile phone middle plate 10 from tilting in the sub-hanger 9.

[0046] See Figure 9As shown, in this embodiment, the front end guide assembly 11 of the middle plate includes a front end guide plate 111. The front and rear sides of the lower end face of the front end guide plate 111 are respectively provided with guide linear guide rails 112. The guide linear guide rails 112 are fixed on the bearing plate 1 by corresponding support seats. The upper end face of the front end guide plate 111 is provided with guide posts 113. The guide posts 113 correspond one-to-one with the middle plate 10 of the mobile phone in the sub-hanger 9. One side of the front end guide plate 111 is connected to the piston rod of a front end guide cylinder 115 through a front end guide connecting block 114. The front end guide cylinder 115 is fixed on the bearing plate 1 by corresponding support seats. The front end guide cylinder 115 drives the front end guide plate 111 to move the guide posts 113 left and right along the guide linear guide rails 112.

[0047] See Figure 10 As shown, in this embodiment, the middle plate rear end guide assembly 12 includes a rear end guide carrier plate 121. The rear end guide carrier plate 121 is disposed in the support plate 41 and can slide within the support plate 41. A guide block 122 is disposed on the upper end surface of the rear end guide carrier plate 121. The number of guide blocks 122 is equal to the number of the maximum number of mobile phone middle plates 10 that can be placed in the sub-hanger 9, and they correspond one-to-one. One side of the rear end guide carrier plate 121 is connected to the piston rod of a rear end guide cylinder 124 through a rear end guide connecting plate 123. The rear end guide cylinder 124 is fixed on the support plate 41 through a corresponding support seat. The rear end guide cylinder 124 drives the rear end guide carrier plate 121 to drive the guide block 122 to slide left and right within the support plate 41. In this embodiment, two sets of the middle plate rear end guide assemblies 12 are provided.

[0048] Furthermore, the mobile phone mid-board mounting and dismounting mechanism also includes a detection sensor 13. The main function of the detection sensor 13 is to detect whether the mobile phone mid-board 10 placed in the sub-mount 9 has been removed.

[0049] The working principle of this invention is as follows:

[0050] When the mobile phone midplate 10 is removed from the sub-hanger 9 after being treated in the anodizing pool, the sub-hanger 9 is first placed on the support plate 41. At this time, the sub-hanger support rod 92 contacts the support plate 41, the lower crossbar 95 of the sub-hanger sinks to the support plate 41, and the two ends of the upper crossbar 91 of the sub-hanger are installed into the limiting grooves 511 on the corresponding sub-hanger support seat 51, thereby limiting the front and rear of the sub-hanger 9. The sub-hanger positioning cylinder 52 extends and presses against the sub-hanger support rod 92, thereby limiting the left and right of the sub-hanger 9. Then, the piston rod of the side wall guiding cylinder 85 extends and drives the side wall guiding carrier plate 8 to move along the side wall guiding linear guide rail 82, thereby driving the guiding component 83 set on the side wall guiding carrier plate 8 to move, so that the mobile phone midplate 10 enters the... Within the U-shaped groove of the corresponding guide member 83, the mobile phone middle plate 10 is guided. After the guidance is completed, the piston rod of the side wall guiding cylinder 85 retracts, causing the guide member 83 to return to its initial position. Then, the motor 74 starts and drives the lead screw 72 to rotate, causing the spring piece lifting hook 77 on the connecting frame 71 to descend to the set lifting height. At this time, the height of the spring piece lifting hook 77 is lower than the height of the spring piece 94. Then, the front and rear transfer cylinders 42 drive the support plate 41 to move along the support linear guide rail 43, thereby causing the sub-hanger 9 on the support plate 41 to move towards the spring piece lifting hook 77 until the spring piece 94 moves to the set position. At this time, the spring piece 94 is located at the corresponding spring piece lifting hook. Above 77; then, the piston rod of the pressing cylinder 61 extends, driving the pressing limit block 62 to move downward and press on the top of the sub-hanger crossbar 91, pressing the sub-hanger 9 onto the support plate 41, thus achieving upper and lower limit of the sub-hanger 9; then, the motor 74 rotates in the opposite direction, driving the spring lifting hook 77 to move upward to the lifting height. At this time, the spring lifting hook 77 lifts the corresponding spring 94 above it, putting the mobile phone middle plate 10 into automatic state. At this time, due to the loss of the fixation of the spring 94, the mobile phone middle plate 10 may tilt, causing the front and rear position deviation of the mobile phone middle plate 10, affecting the material picking in the next process; therefore, the piston rod of the front guide cylinder 115 retracts, driving the front guide carrier plate 1 11 moves along the guide rail 112, thereby driving the guide post 113 to move. At the same time, the piston rod of the rear guide cylinder 124 retracts, driving the rear guide plate 121 to slide within the support plate 41, thereby driving the guide block 122 to move. This achieves the alignment of the guide post 113 and the guide block 122 with the front and rear ends of the mobile phone middle plate 10. After eliminating the deviation, the piston rods of the front guide cylinder 115 and the rear guide cylinder 124 extend, driving the guide post 113 and the guide block 122 to return to their initial state. Then, in the next process, the mobile phone middle plate 10 is removed from the sub-hanger 9. At this time, the detection sensor 13 detects that the mobile phone middle plate 10 has been removed from the sub-hanger 9, and controls the loading process to load the material.

[0051] After the mobile phone midplate 10 is placed in the sub-hanger 9, the piston rod of the side wall guiding cylinder 85 extends to drive the guiding component 83 to move, so that the mobile phone midplate 10 enters the U-shaped groove of the corresponding guiding component 83, thereby guiding the mobile phone midplate 10. At the same time, the piston rods of the front guiding cylinder 115 and the rear guiding cylinder 124 retract, driving the guiding column 113 and the guiding block 122 to move, guiding the front and rear ends of the mobile phone midplate 10. After completion, the side wall guiding cylinder 85 retracts and the front guiding cylinder 115 and the rear guiding cylinder 124 extend, thereby driving the corresponding guiding component 83, driving the guiding column 113 and the guiding block 122 to return to their initial state. Then, motor 74 drives the spring lifting hook 77 to move downward, causing the spring 94 to spring back and press against the mobile phone middle plate 10; then, the piston rod of the pressing cylinder 61 retracts, driving the pressing limit block 62 to move upward, releasing the downward pressure on the sub-hanger 9; then, the front and rear transfer cylinder 42 retracts and drives the support plate 41 to move along the support linear guide rail 43 to the initial position; then, motor 74 drives the spring lifting hook 77 to return to the initial height; then, the piston rod of the sub-hanger positioning cylinder 52 retracts to the initial state, releasing the left and right limits on the sub-hanger 9; then, the next process removes the sub-hanger 9 with the mobile phone middle plate 10 placed on it for surface treatment.

[0052] The above description is merely a preferred embodiment of the present invention and is not intended to limit the invention. Various modifications and variations can be made to the present invention by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the scope of protection of the present invention.
