[0058] The technical solution of the present invention will be further described below in conjunction with the accompanying drawings and through specific implementation manners. It can be understood that the specific embodiments described herein are only used to explain the present invention, rather than limiting the present invention. Additionally, it should be noted that for the convenience of description, only the parts related to the present invention are shown in the drawings, rather than all of them.

[0059] In the present invention, some orientation words are defined. In the case of no contrary description, the orientation words such as "upper", "lower", "left", "right", "inner", and "outer" are used for the convenience of understanding, and thus do not constitute a limitation to the protection scope of the present invention.

[0060] In the present invention, unless otherwise clearly defined and limited, the first feature being "above" or "below" the second feature may include the direct contact between the first and second features, or may include the situation where the first and second features are not in direct contact but in contact through other features between them. Moreover, the first feature being "above", "over", and "on" the second feature includes the first feature being directly above and obliquely above the second feature, or merely indicating that the first feature has a higher horizontal height than the second feature. The first feature being "below", "under", and "beneath" the second feature includes the first feature being directly below and obliquely below the second feature, or merely indicating that the first feature has a lower horizontal height than the second feature.

[0061] In the description of the present invention, unless otherwise clearly defined and limited, the terms "connected", "connected to", and "fixed" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or integrated; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, and it can be the communication inside two components or the interaction relationship between two components. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0062] The assembly device provided in this embodiment is used to assemble the first piece and the third piece onto the second piece. In this embodiment, the assembly of a mobile phone is taken as an example for illustration. The mobile phone includes a main board 20, a middle frame 30, and a card tray 40. The main board 20 is placed at a first preset position of the middle frame 30, and the card tray 40 is inserted into the insertion opening of the middle frame 30. That is, the first piece is the main board 20, the second piece is the middle frame 30, and the third piece 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 main board 20 of the mobile phone, and can also assemble other electronic components.

[0063] As Figure 1 and 2 shown, the assembly device provided in this embodiment includes a bracket 9, a device main body, and a housing 8. The device main body is arranged on the bracket 9, and the housing 8 covers the device main body and the bracket 9 to prevent the device main body from being contaminated, thereby ensuring the assembly accuracy of the device main body.

[0064] The device main body includes a feeding device 1 arranged along the first direction and an assembling device. The feeding device 1 can provide the main board 20 for the assembling device and can continuously feed the assembling device to ensure the working efficiency of the assembly device.

[0065] The specific structure of the feeding device 1 will be introduced first below.

[0066] As Figure 3 shown, the feeding device 1 includes a feeding rack 11, a temporary storage mechanism 12, a lifting mechanism 13, and a handling mechanism 14. The temporary storage mechanism 12 is slidably arranged on the feeding rack 11 along the first direction to switch between the inside 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 in the feeding position, and when the temporary storage mechanism 12 is located outside the feeding rack 11, the temporary storage mechanism 12 is in the loading position.

[0067] The temporary storage mechanism 12 has a full-load part 122 for carrying the full trays 10 and an empty-load part 121 for carrying the empty trays 10. The full-load part 122 and the empty-load part 121 are arranged in the first direction. The lifting mechanism 13 is arranged on the feeding rack 11. When the temporary storage mechanism 12 is in the loading position, the lifting mechanism 13 can lift the tray 10 placed on the full-load part 122 to a preset height. The handling mechanism 14 is arranged at the upper end of the feeding rack 11. When the temporary storage mechanism 12 is in the loading position, the handling mechanism 14 is configured to carry the uppermost tray 10 on the lifting mechanism 13 in the first direction to the empty-load part 121.

[0068] 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. An operator manually places multiple stacked full trays 10 into the full-load part 122, and at the same time takes out the empty trays 10 in the empty-load part 121, and then pushes the trays 10 to the feeding position. The lifting mechanism 13 lifts the tray 10 placed on the full-load part 122 to a preset height so that the assembling device can take away the main board 20 in the uppermost tray 10. When all the main boards 20 in the uppermost tray 10 are taken away, the handling mechanism 14 carries this tray 10 to the empty-load part 121. The lifting mechanism 13 and the handling mechanism 14 repeat the above actions until all the materials in all the trays 10 are taken out. The feeding device 1 provided in this embodiment does not require an operator to manually pick and place individual trays 10, improving the working efficiency and reducing the working intensity.

[0069] As Figure 3 shown, when multiple trays 10 are stacked on the full-load part 122 and the empty-load part 121, in order to prevent the trays 10 from tipping over, the temporary storage mechanism 12 further includes a door body 124 and multiple baffle plates 125. The door body 124 is connected to one end of the empty-load part 121 away from the full-load part 122 and is located outside the feeding rack 11. The multiple baffle plates 125 are arranged at intervals on the outer peripheries of the empty-load part 121 and the full-load part 122. The baffle plates 125 arranged on the outer periphery of the empty-load part 121, the door body 124 and the empty-load part 121 enclose a first space for stacking the empty trays 10, and the baffle plates 125 arranged on the outer periphery of the full-load part 122 and the full-load part 122 enclose a second space for stacking the full trays 10.

[0070] 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.

[0071] As Figure 3 and Figure 4As shown in the figure, specifically, the first driving component is a nut-screw mechanism driven by a pulley and a belt. The first driving component includes a first motor 132, two first driven wheels 133, a first belt 134, and two screws 135. The cylinder block of the first motor 132 is connected to the feeding frame 11, and the driving wheel set 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 sleeved outside the driving wheel set and the two first driven wheels 133. The two screws 135 are arranged at intervals along the second direction and rotatably arranged on the feeding frame 11. The first direction is perpendicular to the second direction. One first driven wheel 133 is connected to the lower end of one screw 135, and the lifting plate 131 is connected to the screw 135 through a nut. When the output shaft of the first motor 132 rotates, it drives 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 screws 135 to rotate clockwise (counterclockwise), so that the nut and the lifting plate 131 rise. When the output shaft of the first motor 132 rotates in the reverse direction, it drives the driving wheel set to rotate in the reverse 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 screws 135 to rotate counterclockwise (clockwise), so that the nut and the lifting plate 131 descend.

[0072] As Figure 4 shown, the driving wheel set 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 block of the first motor 132 is arranged on the feeding frame 11 and can slide along the direction perpendicular to the arrangement direction of the second tensioning wheel 137 and the third tensioning wheel 138. To enable the first motor 132 to slide, the cylinder block of the first motor 132 is connected to the connecting plate 136. The connecting plate 136 is provided with a long hole extending along the sliding direction of the first motor 132. The bracket 9 is provided with a threaded hole. After the first motor 132 slides in place, the bolt passes through the long hole and is connected to the threaded hole. The nut of the bolt abuts against the connecting plate 136 to fix the first motor 132.

[0073] As Figure 3As shown, in order to enable the lifting plate 131 to lift the tray 10 located in the full-load section 122 and not affect the sliding of the temporary storage mechanism 12 in the first direction, two lifting plates 131 are arranged at intervals in the second direction. Avoidance grooves 123 are provided at both ends of the full-load section 122 in the second direction. The lifting plate 131 can pass through the avoidance groove 123 and abut against the lower surface of the lowermost tray 10. After all the trays 10 on the lifting plate 131 are transported to the empty-load section 121 by the handling 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 full-load section 122, so as to prevent the temporary storage mechanism 12 from being pushed to the loading position. After the temporary storage mechanism 12 is in 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 lowermost tray 10, and the first driving component drives the lifting plate 131 to continue moving upward until the uppermost tray 10 reaches the preset height.

[0074] To enable the handling mechanism 14 to handle the tray 10, the handling 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. The second driving component is connected to the connecting frame 141 and drives the connecting frame 141 to reciprocate in the first direction. The first adsorption component 142 is arranged on the connecting frame 141 and can adsorb the tray 10.

[0075] Specifically, the second driving component is a pulley and belt drive 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 in 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 sleeved outside the driving wheel 144 and the second driven wheel 145. 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 in the first direction.

[0076] To avoid interference between the first adsorption assembly 142 of the handling mechanism 14 and the tray 10, the handling mechanism 14 further includes a first lifting driving member 147. The cylinder body of the first lifting driving member 147 is connected to the connection frame 141, and the first adsorption assembly 142 is connected to the output end of the first lifting driving member 147. When it is necessary to adsorb the tray 10, the first driving assembly drives the connection frame 141 to move in the first direction to directly above the tray 10. The first lifting driving member 147 drives the adsorption assembly to move downward to adsorb the tray 10. Then, the first lifting driving member 147 drives the adsorption assembly to move upward, and the first driving assembly drives the connection frame 141 to move in the first direction to directly above the no-load portion 121. The first adsorption assembly 142 cancels the adsorption of the tray 10, and the tray 10 falls under the action of gravity to the no-load portion 121 or onto the tray 10 located at the no-load portion 121.

[0077] The tray 10 falling onto the no-load portion 121 or the tray 10 located at the no-load portion 121 will cause vibration of the temporary storage mechanism 12. However, since the fully loaded tray 10 has been lifted by the lifting plate 131, the fully loaded tray 10 does not contact the temporary storage mechanism 12. Therefore, the materials in the fully loaded tray 10 will not be affected by the vibration of the temporary storage mechanism 12.

[0078] To improve the mechanical compactness of the lifting mechanism 13, the cylinder body of the first lifting driving member 147 is connected to the upper side of the connection frame 141, and its output end slides vertically through the connection frame 141. The first adsorption assembly 142 is located below the first lifting driving member 147.

[0079] As Figure 5 shown, to enable the temporary storage mechanism 12 to slide relative to the feeding rack 11, the feeding device 1 further includes a sliding mechanism 15. The sliding mechanism 15 includes a support body 151, a sliding member 153, and a plurality of spheres 154. Among them, the plurality of spheres 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. The sliding member 153 is connected to the temporary storage mechanism 12, thereby driving the temporary storage mechanism 12 to move in the first direction. The support body 151 is connected to the feeding rack 11 to fix the position of the support body 151. Specifically, the sliding member 153 is slidably disposed outside the support body 151. The support body 151 has a first support surface 1511, and the sliding member 153 has a second support surface 1531. The spheres 154 are rotatably disposed between the first support surface 1511 and the second support surface 1531.

[0080] To avoid the aggregation of multiple spheres 154 caused by the sliding of the sliding member 153, which may lead to unstable sliding of the sliding member 153, the sliding mechanism 15 further includes a limiting member 152. The limiting member 152 is provided with a plurality of limiting holes at intervals in the first direction. Each limiting hole is provided with a sphere 154 that rolls therein. The limiting member 152 can make the spheres 154 evenly distributed in the first direction. The limiting member 152 is connected to the support body 151 to fix the relative positions of the support body 151 and the limiting member 152. Preferably, the first support surface 1511 and the second support surface 1531 are arranged vertically to reduce the friction between the spheres 154 and the inner wall of the limiting holes and reduce the wear of the spheres 154. To increase the contact area between the spheres 154 and the support surfaces, both the first support surface 1511 and the second support surface 1531 are arc-shaped structures.

[0081] 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 in the vertical direction, and the sliding member 153 is provided with two second support surfaces 1531 in the vertical direction. The two first support surfaces 1511 and the two second support surfaces 1531 are arranged opposite to each other respectively. Preferably, two sets of sliding mechanisms 15 are arranged at intervals in the second direction to improve the stability of the movement of the temporary storage mechanism 12.

[0082] As Figure 2 , Figures 6 - 11 shown, the assembling device can respectively place the main board 20 at the first preset position of the middle frame 30 and insert the card tray 40 into the insertion slot of the middle frame 30. The assembling device includes a first conveying mechanism 2, a positioning mechanism 3, a second conveying mechanism 5, and a card inserting mechanism 6. The first conveying mechanism 2 is used to convey the middle frame 30. A manipulator or a worker 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, main board 20, and card tray 40.

[0083] 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 located at the second preset position on the positioning mechanism 3. Thus, the second conveying mechanism 5 can place the main board 20 at the first preset position of the middle frame 30 located on the positioning mechanism 3, and enable the card inserting mechanism 6 to insert the card tray 40 carried by it into the middle frame 30 located on the positioning mechanism 3. To enable the card inserting mechanism 6 to insert the card tray 40 into the insertion slot of the middle frame 30, the card inserting mechanism 6 is arranged on one side of the positioning mechanism 3.

[0084] As 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.

[0085] 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.

[0086] 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.

[0087] Preferably, for installing the first conveying component 21 and the second conveying component 22, the first conveying mechanism 2 further includes a conveying frame 25, and the first conveying component 21 and the second conveying component 22 are arranged on the conveying frame 25.

[0088] To determine the type of the middle frame 30 to avoid mismatch between the middle frame 30, the card slot 40 and the main board 20, the first conveying mechanism 2 further includes a barcode scanner 26 located at the inlet 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.

[0089] Preferably, the first conveying mechanism 2 may further include a temporary storage area 24 arranged on one side of the positioning mechanism 3 along the first direction. The temporary storage area 24 is used to temporarily store the main board 20. When the conveying speed of the main board 20 by the second conveying mechanism 5 is greater than the speed of the position detection mechanism 4 detecting the position of the main board 20, the second conveying mechanism 5 may first place the main board 20 in the temporary storage area 24.

[0090] As Figure 7 shown, to improve the structural compactness of the assembly device, 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, and 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 communicatively connected to the CCD camera. The second conveying mechanism 5 is communicatively 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 separate microcontroller or composed of multiple distributed microcontrollers. A control program can run in the microcontroller to control the above-mentioned various components to realize their functions.

[0091] 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 products.

[0092] As Figure 2 and Figure 8 shown, 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. As 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.

[0093] 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.

[0094] 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.

[0095] Specifically, the buffer assembly 52 includes a fixing plate 521, a sliding plate 522, and an elastic buffer member 523. Among them, the fixing plate 521 is connected to the output end of the rotary driving member 54 of the driving mechanism. The sliding plate 522 is slidably connected to the fixing plate 521 in the vertical direction. The second adsorption assembly 51 is connected to the sliding plate 522. One end of the elastic buffer member 523 is connected to the fixing plate 521, and the other end is connected to the sliding plate 522. Specifically, the elastic buffer member 523 is a spring. The upper end of the spring is connected to the fixing plate 521, and the lower end is connected to the sliding plate 522. When the second adsorption assembly 51 abuts against the main board 20, or the second adsorption assembly 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 member 523 applies a downward force to the sliding plate 522, so that the second adsorption assembly 51 can abut against the main board 20, or the second adsorption assembly 51 drives the main board 20 to abut against the middle frame 30 or the position detection mechanism 4, and can also buffer the second adsorption assembly 51 and the main board 20.

[0096] When the first detection assembly 42 detects the offset of the main board 20 on the support member 41, the second adsorption assembly 51 is in an idle state. Therefore, to improve the working efficiency of the assembly device, the second conveying mechanism 5 further includes a third adsorption assembly 53. The third adsorption assembly 53 is connected to the transfer rack 55 and can adsorb the main board 20. When the first detection assembly 42 detects the offset of the main board 20 on the support member 41, the driving mechanism can drive the third adsorption assembly 53 to adsorb the main board 20. After the second adsorption assembly 51 places the main board 20 in the middle frame 30, the driving mechanism drives the third adsorption assembly 53 to place the adsorbed main board 20 on the support member 41, thereby improving the working efficiency. The first adsorption assembly 142, the second adsorption assembly 51, and the third adsorption assembly 53 provided in this embodiment may all include a suction nozzle and a vacuum generator communicated with the suction nozzle to grasp and release workpieces.

[0097] As Figure 6 and Figure 7 shown, in order to enable the positioning mechanism 3 to fix the middle frame 30 located on the first conveying mechanism 2 and place the middle frame 30 on the positioning mechanism 3 back into the first conveying mechanism 2 again, the positioning mechanism 3 includes a first positioning mechanism. The first positioning mechanism is disposed on the conveying path of the first conveying mechanism 2 in a liftable manner, so that the middle frame 30 is located on the first positioning mechanism and the middle frame 30 is located at a third preset position in the second direction. Specifically, the first positioning mechanism is disposed between the first conveying component 21 and the second conveying component 22 in a liftable manner. When the first positioning mechanism rises to the highest position, the first positioning mechanism lifts the middle frame 30 on the first conveying mechanism 2. When the first positioning mechanism drops to the lowest position, the first positioning mechanism places 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.

[0098] As shown Figure 7 in the figure, 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 respectively driven to lift by an electric cylinder or a cylinder, etc.

[0099] The normal state of the stopper 31 is to rise 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 continuous movement of the middle frame 30. 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 penetrating the support plate are provided on the support plate. The suction nozzles are arranged through the through holes and can adsorb the middle frame 30 located on the support plate.

[0100] In order to make the middle frame 30 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 component. The second stopper 34 is connected to the fourth adsorption component 32. The positioning component 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 component 32 in the second direction. The first driving member can drive the first stopper 35 to approach or move away from the second stopper 34 in the second direction, and the middle frame 30 can be clamped between the first stopper 35 and the second stopper 34. After the fourth adsorption component 32 lifts the middle frame 30, the first driving member drives the first stopper 35 to approach the second stopper 34, so that both sides of the middle frame 30 are respectively abutted against the second stopper 34 and the first stopper 35, thereby realizing the positioning of the middle frame 30 in the second direction. Preferably, the cylinder body of the first driving member is connected to the fourth adsorption component 32 to lift with the fourth adsorption component 32.

[0101] In order to position the middle frame 30 provided on the fourth adsorption component 32 in the first direction, the positioning mechanism 3 further includes two groups of second positioning mechanisms 33, which are symmetrically arranged on both sides of the fourth adsorption component 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 cylinders or electric cylinders, etc.

[0102] The positioning process of the positioning mechanism 3 provided in this embodiment for the middle frame 30 is as follows:

[0103] 1. The stopper 31 stops the middle frame 30 conveyed by the first conveying mechanism 2;

[0104] 2. The fourth adsorption component 32 moves upward, lifts the middle frame 30, and makes a distance between the middle frame 30 and the first conveying mechanism 2;

[0105] 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 both ends of the middle frame 30 along the first direction, so as to realize 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 both ends of the middle frame 30 along the second direction, so as to realize the positioning of the middle frame 30 along the second direction;

[0106] 4. The fourth adsorption component 32 adsorbs the middle frame 30.

[0107] The process of the positioning mechanism 3 provided in this embodiment for placing the middle frame 30 on the first conveying mechanism 2 again is as follows:

[0108] 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 middle frame 30;

[0109] 2. The fourth adsorption component 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 below the middle frame 30, so that the middle frame 30 can continue to move along the second direction under the drive of the first conveying mechanism 2.

[0110] Such as Figures 9 - 11As shown in the figure, the assembling device provided in this embodiment can also be used to insert the card slot 40 into the middle frame 30. The following will introduce the structures involved in inserting the card slot 40 into the slot of the middle frame 30 by the assembling device: the first conveying mechanism 2, the positioning mechanism 3, the card inserting 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 elaborated here. The feeding mechanism 7 is used to place the card slots 40 on the card inserting mechanism 6 one by one, so that the card inserting mechanism 6 inserts the card slot 40 into the middle frame 30 located at the second preset position on the positioning mechanism 3.

[0111] To facilitate the card inserting mechanism 6 to insert the card slot 40 into the middle frame 30, the card inserting mechanism 6 is arranged on one side of the positioning mechanism 3. Specifically, to improve the structural compactness of the assembling device, the position detection mechanism 4, the positioning mechanism 3, and the card inserting mechanism 6 are arranged in sequence along the conveying direction of the first conveying mechanism 2. Further, the position detection mechanism 4, the positioning mechanism 3, and the card inserting mechanism 6 are arranged between the first conveying component 21 and the second conveying component 22. It can be understood that the position of the card inserting mechanism 6 is determined according to the orientation of the slot of the middle frame 30. When the orientation of the slot changes, the position of the card inserting mechanism 6 can be adjusted accordingly.

[0112] As Figure 9 and Figure 10 shown in the figure, the feeding mechanism 7 includes a feeding component 71. The feeding component 71 includes a vibrating disk 711 and a clamping component. A plurality of card slots 40 are arranged in the vibrating disk 711. The vibrating disk 711 is configured to convey the card slots 40 to the outlet of the vibrating disk 711 one by one. The clamping component is arranged on one side of the outlet of the vibrating disk 711. The clamping component is used to receive the card slot 40 output from the outlet of the vibrating disk 711. In this embodiment, to improve the structural compactness of the assembling device, the clamping component and the vibrating disk 711 are arranged along the second direction. The specific structure and working principle of the vibrating disk 711 are prior art, so they will not be elaborated here.

[0113] As Figure 10 shown in the figure, the clamping component includes a jaw cylinder 713 and two relatively arranged jaws 712. The two relatively arranged jaws 712 are connected to the output end of the jaw cylinder 713. The jaw cylinder 713 drives the two jaws 712 to approach or separate from each other. Slots 7121 are arranged on the side where the two jaws 712 approach each other. The card slot 40 can be inserted into the two slots 7121.

[0114] In order to convey the cartridge holder 40 provided by the feeding component 71 to the card inserting mechanism 6, the feeding mechanism 7 further includes a transfer component 72. The transfer component 72 includes a fifth adsorption component 721 and a third driving member 722. The fifth adsorption component 721 is used to grasp the cartridge holder 40 located on the feeding component 71 and place the cartridge holder 40 on the card inserting mechanism 6. The output end of the third driving member 722 is connected to the fifth adsorption component 721 to drive the fifth adsorption component 721 to reciprocate between the feeding component 71 and the card inserting mechanism 6. The fifth adsorption component 721 may include a suction nozzle and a vacuum generator communicated with the suction nozzle to grasp and release the cartridge holder 40.

[0115] Preferably, in order to detect whether there is a cartridge holder 40 between the two clamping jaws 712, a second detection component 73 is arranged below the clamping jaws 712. Both the second detection component 73 and the transfer component 72 are communicatively connected to the controller. When the second detection component 73 detects that there is a cartridge holder 40 between the two clamping jaws 712, the controller controls the transfer component 72 to grasp the cartridge holder 40 located between the two clamping jaws 712. The second detection component 73 is preferably a CCD camera.

[0116] To facilitate the fifth adsorption component 721 to adsorb the cartridge holder 40 located on the clamping component and place the cartridge holder 40 adsorbed by the fifth adsorption component 721 on the card inserting mechanism 6, the transfer component 72 further includes a second lifting driving member 723. The output end of the second lifting driving member 723 is connected to the fifth adsorption component 721, and the cylinder body of the second lifting driving member 723 is connected to the output end of the third driving member 722. The second lifting driving member 723 is used to drive the fifth adsorption component 721 to move in the vertical direction. The third driving member 722 and the second lifting driving member 723 may both be electric cylinders or air cylinders.

[0117] Before the fifth adsorption group adsorbs the cartridge holder 40 located on the clamping component, the second lifting driving member 723 drives the fifth adsorption component 721 to move downward so that the fifth adsorption group contacts the cartridge holder 40 to achieve the adsorption of the cartridge holder 40. After the fifth adsorption group adsorbs the cartridge holder 40 located on the clamping component, the second lifting driving member 723 drives the fifth adsorption component 721 to move upward to prevent the fifth adsorption component 721 from interfering with the clamping component. When the fifth adsorption component 721 needs to place the cartridge holder 40 on the card inserting mechanism 6, the second lifting driving member 723 drives the fifth adsorption component 721 to move downward. After the cartridge holder 40 contacts the card inserting mechanism 6, the fifth adsorption group releases the cartridge holder 40; when the fifth adsorption component 721 needs to place the cartridge holder 40 on the card inserting mechanism 6, the second lifting driving member 723 drives the fifth adsorption component 721 to move upward to prevent the fifth adsorption component 721 from interfering with the card inserting mechanism 6.

[0118] The working process of the feeding component 71 is as follows:

[0119] Step 1: The two jaws 712 maintain a small spacing, and the card holder 40 output by the vibrating disk 711 is inserted into the slots 7121 of the two jaws 712, so as to ensure that the positions of the card holders 40 provided by the vibrating disk 711 are consistent.

[0120] Step 2: The second lifting drive 723 drives the fifth adsorption assembly 721 to move downward, and the fifth adsorption assembly 721 adsorbs the card holder 40 located on the clamping assembly.

[0121] Step 3: The two jaws 712 move away from each other until the card holder 40 disengages from the slot 7121, and the second lifting drive 723 drives the fifth adsorption assembly 721 to move upward.

[0122] Step 4: The third drive 722 drives the fifth adsorption assembly 721 and the second lifting drive 723 to move in the opposite direction of the first direction to directly above the card insertion mechanism 6.

[0123] Step 5: The second lifting drive 723 drives the fifth adsorption assembly 721 to move downward until the card holder 40 contacts the card insertion mechanism 6. The fifth adsorption assembly 721 releases the card holder 40, and the card holder 40 is located on the card insertion mechanism 6.

[0124] Step 6: The second lifting drive 723 drives the fifth adsorption assembly 721 to move upward, and the third drive 722 drives the fifth adsorption assembly 721 and the second lifting drive 723 to move in the first direction to directly above the clamping assembly.

[0125] As Figure 11 shown, the card insertion mechanism 6 includes a guiding member and a pushing assembly 61. The pushing assembly 61 is used to push the card holder 40 into the insertion slot of the middle frame 30. The guiding assembly is used to carry the card holder 40 and guide the card holder 40, so that during the process of the pushing assembly 61 pushing the card holder 40, it is ensured that the card holder 40 moves along a preset direction and is finally inserted into the middle frame 30. Specifically, the guiding member extends along the direction in which the card holder 40 is inserted into the middle frame 30. The guiding member has an avoidance space, and the extending direction of the avoidance space is the same as the extending direction of the guiding member. The pushing assembly 61 includes a pushing drive 611 and a pushing block 612 connected to the output end of the pushing drive 611. The pushing block 612 slidably penetrates through the avoidance space, and the pushing drive 611 can drive the pushing block 612 to reciprocate along the extending direction of the avoidance space. The pushing block 612 can abut against the side of the card holder 40 away from the positioning mechanism 3.

[0126] When it is necessary to push the card tray 40 into the socket of the middle frame 30, the pushing driving member 611 drives the pushing block 612 to abut against the side of the card tray 40 away from the positioning mechanism 3. Then, the pushing driving member 611 continues to drive the pushing block 612 to move towards the middle frame 30 until the card tray 40 is inserted into the middle frame 30. Finally, the pushing driving member 611 drives the pushing block 612 to move in the opposite direction so that the feeding mechanism 7 can place the card tray 40 on the guiding member again.

[0127] In this embodiment, the guiding member includes two guiding plates 62 that are symmetrically arranged at intervals. The two guiding plates 62 enclose an avoidance space. A stepped portion 621 for carrying the card tray 40 is provided at the upper end of the guiding plate 62. The lower end surface of the card tray 40 can abut against the horizontal plane of the stepped portion 621 so that the guiding member can carry the card tray 40. The side surface of the card tray 40 can abut against the vertical surface of the stepped portion 621 so that the guiding plate 62 guides the card tray 40.

[0128] During 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 upwards, the card inserting mechanism 6 further includes a stopping portion 63. The stopping portion 63 is located above the guiding member, and the upper surface of the card tray 40 can contact the lower side of the stopping portion 63.

[0129] Preferably, in order to prevent the card inserting mechanism 6 from affecting the continuous conveyance of the assembled middle frame 30 along the first conveying mechanism 2, the card inserting mechanism 6 may further include a lifting cylinder. The conveying end of the lifting cylinder is connected to the cylinder body of the pushing driving member 611 to drive the pushing driving member 611 to move in the vertical direction.

[0130] The working process of the assembling device provided in this embodiment is as follows:

[0131] Step 1: The first conveying mechanism 2 conveys the middle frame 30 above the positioning mechanism 3. The positioning mechanism 3 positions the middle frame 30 and fixes the middle frame 30.

[0132] Step 2: The second conveying mechanism 5 moves above the feeding device 1 and adsorbs the main board 20 located on the feeding device 1. The second conveying mechanism 5 places the middle frame 30 on the support member 41. The first detection assembly 42 detects the offset of the middle frame 30. The second conveying mechanism 5 adsorbs the middle frame 30 located on the support member 41, and the controller controls the second conveying mechanism 5 to compensate for the offset according to the offset (Step 2 can be carried out simultaneously with Step 1).

[0133] Step 3: The second conveying mechanism 5 places the main board 20 at the first preset position of the middle frame 30 located on the positioning mechanism 3.

[0134] Step 4: The loading mechanism 7 places the card holder 40 on the guiding member of the card inserting mechanism 6, and the pushing component 61 of the card inserting mechanism 6 pushes the card holder 40 placed on the guiding member into the insertion slot of the middle frame 30 (Step 4 can be carried out simultaneously with Step 2 or Step 3);

[0135] 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.

[0136] Obviously, the above embodiments of the present invention are merely examples for clearly explaining the present invention, rather than limiting the implementation manners of the present invention. For those of ordinary skill in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation manners here.
