For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0066] The assembly device provided in this embodiment is used to assemble the first and third components onto the second component. In this embodiment, the assembly device is used to assemble a mobile phone as an example for explanation. The mobile phone includes a motherboard 20, a middle frame 30, and a card tray 40. The motherboard 20 is placed in a first preset position of the middle frame 30, and the card tray 40 is inserted into the socket of the middle frame 30, that is, the first component is the motherboard 20, the second component is the middle frame 30, and the third component is the card tray 40. Of course, the assembly device is not limited to assembling the middle frame 30, the card tray 40, and the motherboard 20 of the mobile phone, and other electronic components can also be assembled.

[0067] like Figure 1 and 2 As shown, the assembly equipment provided in this embodiment includes a bracket 9, a device body and a shell 8. The device body is arranged on the bracket 9, and the shell 8 is covered outside the device body and the bracket 9 to prevent the device body from being contaminated, thereby ensuring the assembly accuracy of the device body.

[0068] The device body includes a feeding device 1 and an assembling device arranged along a first direction. The feeding device 1 can provide a mainboard 20 for the assembling device and can continuously feed the assembling device to ensure the working efficiency of the assembling device.

[0069] The specific structure of the feeding device 1 will be firstly introduced below.

[0070] like Figure 3 As shown, the feeding device 1 includes a feeding rack 11, a temporary storage mechanism 12, a lifting mechanism 13 and a conveying mechanism 14. The temporary storage mechanism 12 is slidably arranged on the feeding rack 11 along a first direction to switch between the inside of the feeding rack 11 and the outside of the feeding rack 11. When the temporary storage mechanism 12 is located inside the feeding rack 11, the temporary storage mechanism 12 is located at the feeding position, and when the temporary storage mechanism 12 is located outside the feeding rack 11, the temporary storage mechanism 12 is located at the loading position.

[0071] The temporary storage mechanism 12 has a fully loaded portion 122 for carrying fully loaded trays 10 and an unloaded portion 121 for carrying unloaded trays 10, and the fully loaded portion 122 and the unloaded portion 121 are arranged along a first direction. The lifting mechanism 13 is arranged on the feeding rack 11. When the temporary storage mechanism 12 is located at the loading position, the lifting mechanism 13 can lift the tray 10 placed on the fully loaded portion 122 to a preset height. The transporting mechanism 14 is arranged at the upper end of the feeding rack 11. When the temporary storage mechanism 12 is located at the loading position, the transporting mechanism 14 is configured to transport the uppermost tray 10 on the lifting mechanism 13 to the unloaded portion 121 along the first direction.

[0072] The working process of the feeding device 1 is as follows: the temporary storage mechanism 12 is pulled out from the feeding rack 11 to the loading position, multiple stacked fully loaded trays 10 are manually placed into the fully loaded part 122, and the unloaded trays 10 in the unloaded part 121 are taken out at the same time, and then the trays 10 are pushed to the feeding position, and the lifting mechanism 13 lifts the trays 10 placed on the fully loaded part 122 to a preset height, so that the assembly device can take away the main board 20 in the uppermost tray 10, and when the main board 20 in the uppermost tray 10 is completely taken away, the transport mechanism 14 transports the tray 10 to the unloaded part 121, and the lifting mechanism 13 and the transport mechanism 14 repeat the above actions until the materials in all the trays 10 are taken out. The feeding device 1 provided in this embodiment does not require manual placement of a single tray 10, thereby improving work efficiency and reducing work intensity.

[0073] like Figure 3 As shown, when multiple material trays 10 are stacked in the full-loaded portion 122 and the empty portion 121, in order to prevent the material trays 10 from tipping over, the temporary storage mechanism 12 further includes a door body 124 and a plurality of baffles 125, wherein the door body 124 is connected to one end of the empty portion 121 away from the full-loaded portion 122 and is located outside the feeding rack 11. The plurality of baffles 125 are arranged at intervals on the periphery of the empty portion 121 and the full-loaded portion 122, and the baffles 125, the door body 124 and the empty portion 121 arranged on the periphery of the empty portion 121 enclose a first space for stacking the empty material trays 10, and the baffles 125 and the full-loaded portion 122 arranged on the periphery of the full-loaded portion 122 enclose a second space for stacking the fully-loaded material trays 10.

[0074] Specifically, the lifting mechanism 13 includes a first driving component connected to the feeding rack 11 and a lifting plate 131 connected to the output end of the first driving component. The first driving component drives the lifting plate 131 to reciprocate in the vertical direction.

[0075] like Figure 3 and Figure 4 As shown, specifically, the first driving assembly is a nut screw mechanism driven by a pulley and a belt, and the first driving assembly includes a first motor 132, two first driven wheels 133, a first belt 134 and two screws 135. The cylinder of the first motor 132 is connected to the feeding rack 11, the driving wheel group is connected to the output shaft of the first motor 132, the two first driven wheels 133 are arranged at intervals along the second direction, the first belt 134 is arranged outside the driving wheel group and the two first driven wheels 133, and the two screws 135 are arranged on the feeding rack 11 at intervals along the second direction and rotatably, and the first direction is perpendicular to the second direction. A first driven wheel 133 is connected to the lower end of a screw 135, and the lifting plate 131 is connected to the screw 135 through a nut. The output shaft of the first motor 132 rotates, driving the driving wheel set to rotate, the driving wheel set drives the first belt 134 to move, the first belt 134 drives the two first driven wheels 133 to rotate clockwise (counterclockwise), the two first driven wheels 133 drive the screw 135 to rotate clockwise (counterclockwise), so that the nut and the lifting plate 131 rise. The output shaft of the first motor 132 rotates in the opposite direction, driving the driving wheel set to rotate in the opposite direction, the driving wheel set drives the belt to move, the belt drives the two first belts 134 to rotate counterclockwise (clockwise), the two first belts 134 drive the screw 135 to rotate counterclockwise (clockwise), so that the nut and the lifting plate 131 fall.

[0076] like Figure 4 As shown, the driving wheel group includes a first tensioning wheel, a second tensioning wheel 137 and a third tensioning wheel 138 arranged in a triangle, the first tensioning wheel is connected to the output end of the first motor 132, the cylinder of the first motor 132 is arranged on the feeding rack 11, and can slide in a direction perpendicular to the arrangement of the second tensioning wheel 137 and the third tensioning wheel 138. In order to enable the first motor 132 to slide, the cylinder of the first motor 132 is connected to the connecting plate 136, and the connecting plate 136 is provided with a long hole extending in the sliding direction of the first motor 132, and the bracket 9 is provided with a threaded hole. After the first motor 132 slides into place, the bolt passes through the long hole and is connected to the threaded hole, and the nut of the bolt abuts against the connecting plate 136 to fix the first motor 132.

[0077] like Figure 3As shown, in order to enable the lifting plate 131 to lift the material tray 10 located in the fully loaded part 122 and not affect the sliding of the temporary storage mechanism 12 in the first direction, two lifting plates 131 are arranged at intervals along the second direction, and avoidance grooves 123 are provided at both ends of the fully loaded part 122 in the second direction, and the lifting plate 131 can pass through the avoidance grooves 123 to abut against the lower surface of the material tray 10 at the bottom. After all the material trays 10 on the lifting plate 131 are transported to the empty part 121 by the transport mechanism 14, the temporary storage mechanism 12 is withdrawn, and the first driving component drives the lifting plate 131 to move downward to a position lower than the fully loaded part 122, thereby preventing the temporary storage mechanism 12 from being pushed to the loading position. When the temporary storage mechanism 12 is located at the feeding position inside the feeding rack 11, the first driving component drives the lifting plate 131 to move upward until it abuts against the lower surface of the material tray 10 located at the bottom, and the first driving component drives the lifting plate 131 to continue to move upward until the material tray 10 located at the top is at a preset height.

[0078] In order to enable the conveying mechanism 14 to convey the material tray 10, the conveying mechanism 14 includes a second driving component, a connecting frame 141 and a first adsorption component 142. The second driving component is arranged at the upper end of the feeding rack 11, and the second driving component is connected to the connecting frame 141, and drives the connecting frame 141 to reciprocate along the first direction. The first adsorption component 142 is arranged in the connecting frame 141, and can adsorb the material tray 10.

[0079] Specifically, the second driving assembly is a pulley and belt transmission structure, which includes a second motor 143, a second belt 146, a driving wheel 144 and a second driven wheel 145. The second motor 143 is connected to the upper end of the feeding rack 11, the driving wheel 144 and the second driven wheel 145 are arranged at intervals along the first direction, the output shaft of the second motor 143 is connected to the driving wheel 144, the second driven wheel 145 is rotatably arranged at the upper end of the feeding rack 11, the second belt 146 is transmission-sleeved outside the driving wheel 144 and the second driven wheel 145, and the connecting frame 141 is connected to the second belt 146. The second motor 143 rotates clockwise and counterclockwise to drive the connecting frame 141 to reciprocate along the first direction.

[0080] To avoid interference between the first adsorption component 142 of the conveying mechanism 14 and the material tray 10, the conveying mechanism 14 also includes a first lifting drive member 147. The cylinder of the first lifting drive member 147 is connected to the connecting frame 141, and the first adsorption component 142 is connected to the output end of the first lifting drive member 147. When it is necessary to adsorb the material tray 10, the first driving component drives the connecting frame 141 to move along the first direction to directly above the material tray 10, and the first lifting drive member 147 drives the adsorption component to move downward to adsorb the material tray 10. Then, the first lifting drive member 147 drives the adsorption component to move upward, and the first driving component drives the connecting frame 141 to move along the first direction to directly above the empty portion 121. The first adsorption component 142 cancels the adsorption of the material tray 10, and the material tray 10 falls to the empty portion 121 or falls onto the material tray 10 located in the empty portion 121 under the action of gravity.

[0081] The material tray 10 falling onto the empty portion 121 or on the material tray 10 located in the empty portion 121 will cause the temporary storage mechanism 12 to vibrate. However, since the fully loaded material tray 10 has been lifted by the lifting plate 131, the fully loaded material tray 10 does not contact the temporary storage mechanism 12. Therefore, the material in the fully loaded material tray 10 will not be affected by the vibration of the temporary storage mechanism 12.

[0082] In order to improve the compactness of the lifting mechanism 13 , the cylinder of the first lifting drive member 147 is connected to the upper side of the connecting frame 141 , and its output end is slidably penetrated in the connecting frame 141 along the vertical direction. The first adsorption component 142 is located below the first lifting drive member 147 .

[0083] like Figure 5 As shown, in order to make the temporary storage mechanism 12 slide relative to the feeding rack 11, the feeding device 1 also includes a sliding mechanism 15, the sliding mechanism 15 includes a support body 151, a sliding member 153 and a plurality of balls 154, wherein the plurality of balls 154 are located between the support body 151 and the sliding member 153, so that the sliding member 153 can slide relative to the support body 151, and the sliding member 153 is connected to the temporary storage mechanism 12, thereby driving the temporary storage mechanism 12 to move along the first direction. The support body 151 is connected to the feeding rack 11 so that the position of the support body 151 is fixed. Specifically, the sliding member 153 is slidably arranged outside the support body 151, the support body 151 has a first supporting surface 1511, the sliding member 153 has a second supporting surface 1531, and the balls 154 are rollingly arranged between the first supporting surface 1511 and the second supporting surface 1531.

[0084] In order to avoid the sliding of the sliding member 153 causing the aggregation of multiple balls 154, which leads to the unstable sliding of the sliding member 153, the sliding mechanism 15 also includes a stopper 152, which is provided with a plurality of stopper holes spaced along the first direction, and each stopper hole is provided with a ball 154 rollingly, and the stopper 152 can make the ball 154 evenly distributed along the first direction. The stopper 152 is connected to the support body 151 to fix the relative position of the support body 151 and the stopper 152. Preferably, the first support surface 1511 and the second support surface 1531 are arranged up and down to reduce the friction between the ball 154 and the inner wall of the stopper hole, and reduce the wear of the ball 154. In order to increase the contact area between the ball 154 and the support surface, the first support surface 1511 and the second support surface 1531 are both arc-shaped structures.

[0085] In order to improve the stability of the movement of the temporary storage mechanism 12, the support body 151 is provided with two first support surfaces 1511 along the vertical direction, and the sliding member 153 is provided with two second support surfaces 1531 along the vertical direction, and the two first support surfaces 1511 and the two second support surfaces 1531 are respectively arranged opposite to each other. Preferably, two sets of sliding mechanisms 15 are arranged at intervals along the second direction to improve the stability of the movement of the temporary storage mechanism 12.

[0086] like Figure 2 , Figure 6-Figure 11 As shown, the assembly device can place the mainboard 20 at the first preset position of the middle frame 30 and insert the card tray 40 into the socket of the middle frame 30 respectively. The assembly device includes a first conveying mechanism 2, a positioning mechanism 3, a second conveying mechanism 5 and a card insertion mechanism 6. The first conveying mechanism 2 is used to convey the middle frame 30. A robot or a person manually places the unassembled middle frame 30 at the inlet end of the first conveying mechanism 2, and the outlet end of the first conveying mechanism 2 outputs the assembled middle frame 30, the mainboard 20 and the card tray 40.

[0087] During the process of the first conveying mechanism 2 conveying the middle frame 30, the positioning mechanism 3 can make the middle frame 30 conveyed along the first conveying mechanism 2 be located at the second preset position on the positioning mechanism 3, so that the second conveying mechanism 5 can place the mainboard 20 at the first preset position of the middle frame 30 located on the positioning mechanism 3, and make the card insertion mechanism 6 insert the card tray 40 carried by it into the middle frame 30 located on the positioning mechanism 3. In order to enable the card insertion mechanism 6 to insert the card tray 40 into the socket of the middle frame 30, the card insertion mechanism 6 is arranged on one side of the positioning mechanism 3.

[0088] like Figure 2As shown, in order to be able to feed the card insertion mechanism 6, preferably, the device body may further include a feeding mechanism 7 for temporarily storing the card tray 40. In order to improve the compactness of the structure of the assembly device, preferably, the feeding device 1, the first conveying mechanism 2 and the feeding mechanism 7 are sequentially arranged along the first direction, and the second conveying mechanism 5 is arranged on the upper side of the first conveying mechanism 2 and the feeding device 1. The second conveying mechanism 5 can grab the mainboard 20 temporarily stored by the feeding device 1 to place the mainboard 20 on the first preset position of the middle frame 30.

[0089] like Figure 6 As shown, the following will introduce the structures involved in the assembly device placing the mainboard 20 at the first preset position of the middle frame 30: the first conveying mechanism 2, the positioning mechanism 3 and the second conveying mechanism 5. In addition, the assembly device also includes a position detection mechanism 4. When the first conveying mechanism 2 conveys the middle frame 30 to the top of the positioning mechanism 3, the positioning mechanism 3 fixes the position of the middle frame 30, and the second conveying mechanism 5 places the mainboard 20 at the first preset position of the middle frame 30 to achieve the assembly of the mainboard 20 and the middle frame 30. Specifically, the second conveying mechanism 5 will move to the material tray 10 of the feeding device 1 to grab the mainboard 20, and then place the mainboard 20 on the position detection mechanism 4. The position detection mechanism 4 detects the offset of the mainboard 20 thereon, and the second conveying mechanism 5 grabs the mainboard 20 located on the position detection mechanism 4 and compensates for the offset to place the mainboard 20 at the first preset position of the middle frame 30 located on the positioning mechanism 3. The assembly device provided in this embodiment can automatically assemble the middle frame 30 and the main board 20. The positioning mechanism 3, the position detection mechanism 4 and the second conveying mechanism 5 can ensure the accurate relative position of the main board 20 and the middle frame 30, thereby improving the assembly efficiency, reducing the assembly tolerance and improving the product qualification rate.

[0090] like Figure 6 As shown, in order to enable the first conveying mechanism 2 to convey the middle frame 30, the first conveying mechanism 2 includes a first conveying assembly 21 and a second conveying assembly 22 spaced apart along the first direction, and the two ends of the length direction of the middle frame 30 are placed on the first conveying assembly 21 and the second conveying assembly 22, so that the first conveying assembly 21 and the second conveying assembly 22 convey the middle frame 30 along the second direction. Specifically, the first conveying assembly 21 and the second conveying assembly 22 are preferably belt and pulley transmission structures. In order to enable the first conveying assembly 21 and the second conveying assembly 22 to move synchronously, the driving pulley of the first conveying assembly 21 and the driving pulley of the second conveying assembly 22 are connected by transmission. Since the belt and pulley transmission structure is a prior art, it will not be repeated here. In other embodiments, the first conveying mechanism 2 can also be other structures, as long as it can transmit the middle frame 30.

[0091] Preferably, in order to install the first conveying assembly 21 and the second conveying assembly 22 , the first conveying mechanism 2 further includes a conveying frame 25 , and the first conveying assembly 21 and the second conveying assembly 22 are arranged on the conveying frame 25 .

[0092] In order to determine the type of the middle frame 30 to avoid the mismatch between the middle frame 30 and the card tray 40 and the main board 20, the first conveying mechanism 2 further includes a barcode scanner 26, which is located at the entrance end of the first conveying mechanism 2. The scanner is used to identify the barcode containing signal information on the middle frame 30 to determine the type of the middle frame 30. The barcode scanner 26 is preferably arranged on the conveying frame 25.

[0093] Preferably, the first conveying mechanism 2 may further include a temporary storage area 24, which is disposed on one side of the positioning mechanism 3 along the first direction, and is used to temporarily store the main board 20. When the speed of the second conveying mechanism 5 conveying the main board 20 is greater than the speed at which the position detection mechanism 4 detects the position of the main board 20, the second conveying mechanism 5 may first temporarily place the main board 20 in the temporary storage area 24.

[0094] like Figure 7 As shown, in order to improve the compactness of the assembly structure, the position detection mechanism 4 is located on one side of the positioning mechanism 3. The position detection mechanism 4 includes a support member 41 and a first detection component 42. The support member 41 can carry the main board 20. The first detection component 42 is used to detect the offset of the main board 20 located on the support member 41. The first detection component 42 is preferably a CCD camera. The CCD camera can capture the position of the middle frame 30, so as to determine the offset of the middle frame 30 through a controller connected to the CCD camera. The second conveying mechanism 5 is connected to the first detection component 42 through the controller, so that the controller controls the second conveying mechanism 5 to compensate for the offset. In this embodiment, the controller can be centralized or distributed. For example, the controller can be a single single-chip microcomputer or a distributed plurality of single-chip microcomputers. The control program can be run in the single-chip microcomputer to control the above-mentioned components to realize their functions.

[0095] The assembly device provided in this embodiment can realize the automatic assembly of the middle frame 30 and the main board 20, and ensure the assembly accuracy between the middle frame 30 and the main board 20 through the positioning mechanism 3, the position detection mechanism 4 and the second conveying mechanism 5, thereby improving the assembly efficiency and ensuring the qualified rate of the product.

[0096] like Figure 2 and Figure 8 As shown, in order to facilitate the second conveying mechanism 5 to convey the main board 20 between the feeding device 1 and the first conveying mechanism 2, preferably, the second conveying mechanism 5 is located above the feeding device 1 and the first conveying mechanism 2. Figure 8As shown, the second conveying mechanism 5 includes a second adsorption component 51 and a driving mechanism. The second adsorption component 51 can adsorb the mainboard 20. The output end of the driving mechanism is connected to the second adsorption component 51 to drive the second adsorption component 51 to move in the first direction and the second direction, and drive the second adsorption component 51 to rotate around the vertical axis. The second adsorption component 51 moves in the first direction and the second direction to adsorb the mainboard 20 on the temporary storage mechanism 12, transport the mainboard 20 to the position detection mechanism 4, and transport the mainboard 20 of the position detection mechanism 4 to the middle frame 30. The second adsorption component 51 moves in the first direction and the second direction, and rotates around the vertical axis to compensate for the offset of the mainboard 20.

[0097] In order to install the driving mechanism, the second conveying mechanism 5 also includes a mounting frame, which is arranged above the first conveying mechanism 2. The driving mechanism includes a rotating driving member 54, an adapter frame 55, a third driving assembly and a fourth driving assembly. The fourth driving assembly is arranged on the mounting frame, and the output end of the fourth driving assembly is connected to the third driving assembly and is used to drive the third driving assembly to move in the first direction. The output end of the third driving assembly is connected to the adapter frame 55, and can drive the adapter frame 55 to move in the second direction. The output end of the rotating driving member 54 is connected to the second adsorption assembly 51, and the cylinder body of the rotating driving member 54 is connected to the adapter frame 55. It can be understood that the third driving assembly and the fourth driving assembly can be a screw rod, a nut driving assembly, a belt and pulley driving assembly or a linear motor, etc., and the rotating driving member 54 can be a motor, etc.

[0098] like Figure 8 As shown, since the second adsorption component 51 needs to abut against the mainboard 20 when adsorbing, the second adsorption component 51 needs to abut the mainboard 20 against the middle frame 30 or the position detection mechanism 4 when releasing the mainboard 20. In order to avoid hard contact between the second adsorption component 51 and the mainboard 20, and to avoid hard contact between the mainboard 20 and the middle frame 30 or the position detection mechanism 4 to damage the mainboard 20, preferably, the second conveying mechanism 5 also includes a buffer component 52.

[0099] Specifically, the buffer component 52 includes a fixed plate 521, a sliding plate 522 and an elastic buffer 523, wherein the fixed plate 521 is connected to the output end of the rotating driving member 54 of the driving mechanism, the sliding plate 522 is slidably connected to the fixed plate 521 along the vertical direction, the second adsorption component 51 is connected to the sliding plate 522, one end of the elastic buffer 523 is connected to the fixed plate 521, and the other end is connected to the sliding plate 522. Specifically, the elastic buffer 523 is a spring, the upper end of the spring is connected to the fixed plate 521, and the lower end is connected to the sliding plate 522. When the second adsorption component 51 abuts against the main board 20, or the second adsorption component 51 drives the main board 20 to abut against the middle frame 30 or the position detection mechanism 4, the sliding plate 522 slides upward in the vertical direction, and the elastic buffer 523 applies a downward force to the sliding plate 522, thereby enabling the second adsorption component 51 to abut against the main board 20, or the second adsorption component 51 drives the main board 20 to abut against the middle frame 30 or the position detection mechanism 4, and also providing a buffering effect on the second adsorption component 51 and the main board 20.

[0100] When the first detection component 42 detects the offset of the mainboard 20 on the support 41, the second adsorption component 51 is in an idle state. Therefore, in order to improve the working efficiency of the assembly device, the second conveying mechanism 5 also includes a third adsorption component 53, which is connected to the adapter frame 55 and can adsorb the mainboard 20. When the first detection component 42 detects the offset of the mainboard 20 on the support 41, the driving mechanism can drive the third adsorption component 53 to adsorb the mainboard 20. After the second adsorption component 51 places the mainboard 20 in the middle frame 30, the driving mechanism drives the third adsorption component 53 to place the adsorbed mainboard 20 on the support 41, thereby improving the working efficiency. The first adsorption component 142, the second adsorption component 51 and the third adsorption component 53 provided in this embodiment can all include a suction nozzle and a vacuum generator connected to the suction nozzle to grab and release the workpiece.

[0101] like Figure 6 and Figure 7 As shown, in order to enable the positioning mechanism 3 to fix the middle frame 30 located on the first conveying mechanism 2 and to place the middle frame 30 on the positioning mechanism 3 in the first conveying mechanism 2 again, the positioning mechanism 3 includes a first positioning mechanism. The first positioning mechanism is movably arranged on the conveying path of the first conveying mechanism 2 so that the middle frame 30 is located in the first positioning mechanism and the middle frame 30 is located in the third preset position in the second direction. Specifically, the first positioning mechanism is movably arranged between the first conveying assembly 21 and the second conveying assembly 22. When the first positioning mechanism is raised to the highest position, the first positioning mechanism lifts the middle frame 30 on the first conveying mechanism 2. When the first positioning mechanism is lowered to the lowest position, the first positioning mechanism puts the assembled middle frame 30 back on the first conveying mechanism 2 again, so that the first conveying mechanism 2 can continue to convey the middle frame 30.

[0102] like Figure 7 As shown, specifically, the first positioning mechanism includes a stopper 31 and a fourth adsorption component 32. The stopper 31 and the fourth adsorption component 32 are arranged along the conveying direction of the first conveying mechanism 2, the stopper 31 can stop the middle frame 30, and the fourth adsorption component 32 can carry and adsorb the middle frame 30. Specifically, the stopper 31 and the fourth adsorption component 32 can be driven to rise and fall respectively by an electric cylinder or a pneumatic cylinder.

[0103] The stopper 31 is normally raised to a higher position. When the middle frame 30 moves to the front side of the stopper 31 under the action of the first conveying mechanism 2, the stopper 31 can limit the middle frame 30 from continuing to move. At this time, the fourth adsorption component 32 rises, carries the middle frame 30 and lifts the middle frame 30, so that the middle frame 30 leaves the first conveying mechanism 2. Specifically, the fourth adsorption component 32 includes a support plate, and a plurality of through holes are formed on the support plate. The suction nozzle is penetrated in the through holes and can adsorb the middle frame 30 located on the support plate.

[0104] In order to make the middle frame 30 be located at the third preset position of the positioning mechanism 3 in the second direction, the first positioning mechanism further includes a second stopper 34 and a positioning assembly. The second stopper 34 is connected to the fourth adsorption assembly 32. The positioning assembly includes a first driving member and a first stopper 35 arranged at the output end of the first driving member, the first stopper 35 and the second stopper 34 are respectively located on both sides of the fourth adsorption assembly 32 along the second direction, the first driving member can drive the first stopper 35 to approach or move away from the second stopper 34 along the second direction, and the middle frame 30 can be sandwiched between the first stopper 35 and the second stopper 34. After the fourth adsorption assembly 32 lifts the middle frame 30, the first driving member drives the first stopper 35 to approach the second stopper 34, so that the two sides of the middle frame 30 are respectively in contact with the second stopper 34 and the first stopper 35, thereby realizing the positioning of the middle frame 30 along the second direction. Preferably, the cylinder of the first driving member is connected to the fourth adsorption assembly 32 to rise and fall with the fourth adsorption assembly 32.

[0105] In order to position the middle frame 30 disposed on the fourth adsorption assembly 32 in the first direction, the positioning mechanism 3 also includes two groups of second positioning mechanisms 33, and the two groups of second positioning mechanisms 33 are symmetrically arranged on both sides of the fourth adsorption assembly 32 along the first direction, so that the middle frame 30 is located at the fourth preset position in the first direction. It can be understood that when the middle frame 30 is located at the third preset position in the second direction and at the fourth preset position in the first direction, the middle frame 30 is located at the second preset position of the positioning mechanism 3. Specifically, the second positioning mechanism 33 includes a second driving member 331 and a positioning block 332 connected to the second driving member 331, and the second driving member 331 drives the positioning block 332 to reciprocate along the first direction. The two groups of second driving members 331 respectively drive the two groups of positioning blocks 332 to approach each other and abut against the middle frame 30, so that the middle frame 30 is located at the fourth preset position in the first direction. The first driving member and the second driving member 331 can be a cylinder or an electric cylinder, etc.

[0106] The positioning mechanism 3 provided in this embodiment is used for positioning the middle frame 30 in the following process:

[0107] 1. The stopper 31 stops the middle frame 30 transported by the first transport mechanism 2;

[0108] 2. The fourth adsorption assembly 32 moves upward to lift the middle frame 30, and a distance is set between the middle frame 30 and the first conveying mechanism 2;

[0109] 3. The two groups of second driving members 331 respectively drive the two groups of positioning blocks 332 to approach each other and abut against the two ends of the middle frame 30 along the first direction, thereby realizing the positioning of the middle frame 30 along the first direction; the first driving member drives the first stopper 35 to approach the second stopper 34 and abut against the two ends of the middle frame 30 along the second direction, thereby realizing the positioning of the middle frame 30 along the second direction;

[0110] 4. The fourth adsorption component 32 adsorbs the middle frame 30 .

[0111] The process of the positioning mechanism 3 provided in this embodiment placing the middle frame 30 on the first conveying mechanism 2 again is as follows:

[0112] 1. The two groups of second driving members 331 respectively drive the two groups of positioning blocks 332 to move away from each other, the first driving member drives the first stopper 35 to move away from the second stopper 34, and the fourth adsorption component 32 cancels the adsorption of the center frame 30;

[0113] 2. The fourth adsorption assembly 32 moves downward until the middle frame 30 is placed on the first conveying mechanism 2, and the stopper 31 moves downward and is located at the lower side of the middle frame 30, so that the middle frame 30 can continue to move in the second direction under the drive of the first conveying mechanism 2.

[0114] like Figure 9-11As shown, the assembly device provided in this embodiment can also be used to insert the card tray 40 into the middle frame 30. The following will introduce the structures involved in the assembly device inserting the card tray 40 into the socket of the middle frame 30: the first conveying mechanism 2, the positioning mechanism 3, the card insertion mechanism 6 and the feeding mechanism 7. Since the functions and specific structures of the first conveying mechanism 2 and the positioning mechanism 3 have been specifically introduced above, they will not be repeated here. The feeding mechanism 7 is used to place the card tray 40 on the card insertion mechanism 6 one by one, so that the card insertion mechanism 6 inserts the card tray 40 into the middle frame 30 located at the second preset position on the positioning mechanism 3.

[0115] In order to facilitate the card insertion mechanism 6 to insert the card tray 40 into the middle frame 30, the card insertion mechanism 6 is arranged on one side of the positioning mechanism 3. Specifically, in order to improve the structural compactness of the assembly device, the position detection mechanism 4, the positioning mechanism 3 and the card insertion mechanism 6 are arranged in sequence along the conveying direction of the first conveying mechanism 2. Furthermore, the position detection mechanism 4, the positioning mechanism 3 and the card insertion mechanism 6 are arranged between the first conveying assembly 21 and the second conveying assembly 22. It can be understood that the position of the card insertion mechanism 6 is determined according to the orientation of the socket of the middle frame 30. When the orientation of the socket changes, the position of the card insertion mechanism 6 can be adjusted accordingly.

[0116] like Fig. 9 and Fig.10 As shown, the feeding mechanism 7 includes a feeding assembly 71, and the feeding assembly 71 includes a vibration plate 711 and a clamping assembly. A plurality of trays 40 are arranged in the vibration plate 711, and the vibration plate 711 is configured to transport the trays 40 to the outlet of the vibration plate 711 one by one. The clamping assembly is arranged on one side of the outlet of the vibration plate 711, and the clamping assembly is used to receive the trays 40 output from the outlet of the vibration plate 711. In this embodiment, in order to improve the compactness of the structure of the assembly equipment, the clamping assembly and the vibration plate 711 are arranged along the second direction. The specific structure and working principle of the vibration plate 711 are prior art, and therefore, they are not described here in detail.

[0117] like Fig.10 As shown, the clamping assembly includes a clamping cylinder 713 and two clamping jaws 712 arranged opposite to each other. The two clamping jaws 712 arranged opposite to each other are connected to the output end of the clamping cylinder 713. The clamping cylinder 713 drives the two clamping jaws 712 to move closer to or away from each other. A slot 7121 is provided on the side where the two clamping jaws 712 are close to each other, and the tray 40 can be inserted into the two slots 7121.

[0118] In order to convey the card tray 40 provided by the feeding assembly 71 to the card insertion mechanism 6, the feeding mechanism 7 further includes a transfer assembly 72, which includes a fifth adsorption assembly 721 and a third driving member 722. The fifth adsorption assembly 721 is used to grab the card tray 40 on the feeding assembly 71 and place the card tray 40 on the card insertion mechanism 6. The output end of the third driving member 722 is connected to the fifth adsorption assembly 721 to drive the fifth adsorption assembly 721 to reciprocate between the feeding assembly 71 and the card insertion mechanism 6. The fifth adsorption assembly 721 may include a suction nozzle and a vacuum generator connected to the suction nozzle to grab and release the card tray 40.

[0119] Preferably, in order to detect whether there is a card tray 40 between the two clamping jaws 712, a second detection component 73 is provided below the clamping jaws 712, and the second detection component 73 and the transfer component 72 are both connected to the controller for communication. When the second detection component 73 detects that there is a card tray 40 between the two clamping jaws 712, the controller controls the transfer component 72 to grab the card tray 40 between the two clamping jaws 712. The second detection component 73 is preferably a CCD camera.

[0120] In order to facilitate the fifth adsorption component 721 to adsorb the card tray 40 located on the clamping component, and to place the card tray 40 adsorbed by the fifth adsorption component 721 on the card insertion mechanism 6, the transfer component 72 also includes a second lifting drive 723, the output end of the second lifting drive 723 is connected to the fifth adsorption component 721, the cylinder body of the second lifting drive 723 is connected to the output end of the third drive 722, and the second lifting drive 723 is used to drive the fifth adsorption component 721 to move in the vertical direction. The third drive 722 and the second lifting drive 723 can both be electric cylinders or pneumatic cylinders.

[0121] Before the fifth adsorption group adsorbs the card tray 40 located on the clamping assembly, the second lifting drive 723 drives the fifth adsorption assembly 721 to move downward so that the fifth adsorption group contacts the card tray 40 to achieve adsorption of the card tray 40. After the fifth adsorption group adsorbs the card tray 40 located on the clamping assembly, the second lifting drive 723 drives the fifth adsorption assembly 721 to move upward to avoid interference between the fifth adsorption assembly 721 and the clamping assembly. When the fifth adsorption assembly 721 needs to place the card tray 40 on the card insertion mechanism 6, the second lifting drive 723 drives the fifth adsorption assembly 721 to move downward, and after the card tray 40 contacts the card insertion mechanism 6, the fifth adsorption group releases the card tray 40; when the fifth adsorption assembly 721 needs to place the card tray 40 on the card insertion mechanism 6, the second lifting drive 723 drives the fifth adsorption assembly 721 to move upward to avoid interference between the fifth adsorption assembly 721 and the card insertion mechanism 6.

[0122] The working process of the feeding component 71 is:

[0123] Step 1, the two clamping jaws 712 maintain a small distance, and the card tray 40 output by the vibration plate 711 is inserted into the slots 7121 of the two clamping jaws 712, so as to ensure that the positions of the card trays 40 provided by the vibration plate 711 are consistent;

[0124] Step 2: The second lifting driving member 723 drives the fifth adsorption component 721 to move downward, and the fifth adsorption component 721 adsorbs the card tray 40 located on the clamping component;

[0125] Step 3, the two clamping claws 712 move away from each other until the card tray 40 is out of the slot 7121, and the second lifting driving member 723 drives the fifth adsorption assembly 721 to move upward;

[0126] Step 4: The third driving member 722 drives the fifth adsorption assembly 721 and the second lifting driving member 723 to move in the opposite direction of the first direction to just above the card insertion mechanism 6;

[0127] Step 5: The second lifting drive member 723 drives the fifth adsorption assembly 721 to move downward until the card tray 40 contacts the card insertion mechanism 6, and the fifth adsorption assembly 721 releases the card tray 40, so that the card tray 40 is located on the card insertion mechanism 6;

[0128] Step 6: The second lifting drive member 723 drives the fifth adsorption assembly 721 to move upward, and the third drive member 722 drives the fifth adsorption assembly 721 and the second lifting drive member 723 to move along the first direction to just above the clamping assembly.

[0129] like Fig.11 As shown, the card insertion mechanism 6 includes a guide member and a push assembly 61, wherein the push assembly 61 is used to push the card tray 40 into the socket of the middle frame 30, and the guide assembly is used to carry the card tray 40 and guide the card tray 40, so that the push assembly 61 ensures that the card tray 40 moves along a preset direction during the process of pushing the card tray 40, and finally inserts it into the middle frame 30. Specifically, the guide member extends along the direction in which the card tray 40 is inserted into the middle frame 30, and the guide member has an escape space, and the extension direction of the escape space is consistent with the extension direction of the guide member. The push assembly 61 includes a push driving member 611 and a push block 612 connected to the output end of the push driving member 611, and the push block 612 is slidably arranged in the escape space, and the push driving member 611 can drive the push block 612 to reciprocate along the direction in which the escape space extends. The push block 612 can abut against the side of the card tray 40 away from the positioning mechanism 3.

[0130] When the card tray 40 needs to be pushed into the socket of the middle frame 30, the push driving member 611 drives the push block 612 to abut against the side of the card tray 40 away from the positioning mechanism 3, and then the push driving member 611 continues to drive the push block 612 to move toward the middle frame 30 until the card tray 40 is inserted into the middle frame 30. Finally, the push driving member 611 drives the push block 612 to move in the opposite direction so that the loading mechanism 7 can place the card tray 40 on the guide again.

[0131] In this embodiment, the guide member includes two guide plates 62 that are symmetrically arranged at intervals, and the two guide plates 62 enclose an avoidance space. A step portion 621 for carrying the card tray 40 is provided at the upper end of the guide plate 62. The lower end surface of the card tray 40 can abut against the horizontal surface of the step portion 621 so that the guide member carries the card tray 40, and the side surface of the card tray 40 can abut against the vertical surface of the step portion 621 so that the guide plate 62 guides the card tray 40.

[0132] In the process of the pushing assembly 61 pushing the card tray 40, in order to prevent the end of the card tray 40 away from the pushing block 612 from tilting upward, the card insertion mechanism 6 also includes a stopper 63, which is located on the upper side of the guide member, and the upper surface of the card tray 40 can contact the lower side of the stopper 63.

[0133] Preferably, in order to prevent the card insertion mechanism 6 from affecting the continued conveying of the assembled middle frame 30 along the first conveying mechanism 2, the card insertion mechanism 6 can also include a lifting cylinder, the conveying end of the lifting cylinder is connected to the cylinder body of the push driving member 611 to drive the push driving member 611 to move in the vertical direction.

[0134] The working process of the assembly device provided in this embodiment is as follows:

[0135] Step 1: The first conveying mechanism 2 conveys the middle frame 30 to the top of the positioning mechanism 3, and the positioning mechanism 3 positions the middle frame 30 and fixes the middle frame 30;

[0136] Step 2, the second conveying mechanism 5 moves to the top of the feeding device 1, and absorbs the mainboard 20 on the feeding device 1; the second conveying mechanism 5 places the middle frame 30 on the support 41, the first detection component 42 detects the offset of the middle frame 30, the second conveying mechanism 5 absorbs the middle frame 30 on the support 41, and the controller controls the second conveying mechanism 5 to compensate for the offset according to the offset (step 2 can be performed simultaneously with step 1);

[0137] Step 3: The second conveying mechanism 5 places the mainboard 20 at a first preset position of the middle frame 30 on the positioning mechanism 3;

[0138] Step 4, the feeding mechanism 7 places the card tray 40 on the guide member of the card insertion mechanism 6, and the push component 61 of the card insertion mechanism 6 pushes the card tray 40 placed on the guide member into the socket of the middle frame 30 (step 4 can be performed simultaneously with step 2 or step 3);

[0139] Step 5: The positioning mechanism 3 places the assembled middle frame 30 on the first conveying mechanism 2 , and the first conveying mechanism 2 conveys the assembled middle frame 30 to the outlet end of the first conveying mechanism 2 .
