[0003] The electronic components can be chips, capacitors, resistors or card holders. Among them, the upper surfaces of electronic components such as chips, capacitors and resistors are relatively flat and can form an attraction plane. When mounting these electronic components, the adsorption end of the mounting suction cup is in contact with the upper surface of these electronic components, and the inside of the mounting suction cup is evacuated so that the adsorption end of the mounting suction cup adsorbs these electronic components, and these electronic components are moved to the circuit board for mounting. However, the card holder needs to be plugged with a memory chip, and the upper surface of the card holder is not flat and cannot form an attraction plane. In the related art, before mounting the card holder, it is necessary to first attach a Mylar sheet to the upper surface of the card holder, and the Mylar sheet forms an attraction plane. Then, the adsorption end of the mounting suction cup is adsorbed on the Mylar sheet, and the card holder is moved to the circuit board for mounting. After mounting, the Mylar sheet needs to be torn off from the card holder.

[0004] The Mylar sheet is arranged on the card holder for mounting, so that the mounting process of the card holder is inefficient and the mounting yield is low. Utility Model Content

[0064] The terms used in the implementation method part of this application are only used to explain the specific embodiments of this application, and are not intended to limit this application. The implementation method of the embodiments of this application will be described in detail below with reference to the accompanying drawings.

[0065] A variety of electronic components are arranged on the circuit board of the computing device. These electronic components are mounted on the circuit board and soldered to the pads on the circuit board.

[0066] Figure 1 It is a schematic diagram of the structure of the mounting suction cup; Figure 2 For along Figure 1 The cross-sectional view of the AA plane in Figure 1 The relative positions of the mounting suction cup and the card holder are also shown.

[0067] See also Figure 1 and Figure 2 As shown, the mounting suction cup 10 includes a suction cup body 11 and a suction head 12, and a chamber 13 is provided between the suction cup body 11 and the suction head 12. When mounting electronic components, the surface of the suction head 12 is in contact with the surface of the electronic components, and the chamber 13 in the mounting suction cup 10 is evacuated, and the suction head 12 can absorb the electronic components, thereby moving the electronic components to corresponding positions on the circuit board.

[0068] The electronic components may be chips, capacitors, resistors or card holders 20. Among them, the upper surfaces of electronic components such as chips, capacitors and resistors are relatively flat and can form a suction plane. When mounting these electronic components, the suction end 12 of the mounting suction cup 10 is in contact with the upper surface of these electronic components, and the inside of the mounting suction cup 10 is evacuated so that the suction end 12 of the mounting suction cup 10 absorbs these electronic components, and these electronic components are moved to the circuit board for mounting.

[0069] Figure 3 It is a structural schematic diagram of the card holder and the circuit board; Figure 4 It is a structural diagram of the card holder.

[0070] See also Figure 3 and Figure 4 As shown, the card holder 20 can be set on the circuit board 30, and the card holder 20 is used to plug the memory. The number of the card holders 20 on the circuit board 30 is set according to the number of the memory. Figure 3 In the figure, a card holder 20 is schematically shown on a circuit board 30.

[0071] Figure 3 and Figure 4 The card holder 20 in the figure is a card holder for inserting a dual inline memory module (DIMM). The card holder 20 can be rectangular, and has a slot 21 on the card holder 20. The inner wall of the slot 21 has two rows of pins 22. The dual inline memory module is inserted into the slot 21 to be electrically connected with the pins 22 on the inner wall of the slot 21. The card holder 20 also includes two side walls 23 opposite to each other along a first direction X. The two side walls 23 are respectively a first side wall 23a and a second side wall 23b. The first side wall 23a and the second side wall 23b can be used to support the dual inline memory module. The slot 21 makes the upper surface of the card holder 20 uneven and cannot form a suction plane.

[0072] Figure 5 Schematic diagram of the structure of setting Mylar sheet on the card seat Figure 1 .

[0073] See also Figure 5 As shown, in the related art, before mounting the card holder 20, it is necessary to first mount a Mylar sheet 40 on the upper surface of the card holder 20, and the Mylar sheet 40 forms an abutting plane, and then the abutting end 12 of the mounting suction cup 10 is adsorbed on the Mylar sheet 40, and the card holder 20 is moved to the circuit board 30 for mounting. After the mounting is completed, the Mylar sheet 40 needs to be torn off from the card holder 20. When mounting the card holder 20, the steps of mounting the Mylar sheet 40 and tearing off the Mylar sheet 40 are added, making the mounting process of the card holder 20 less efficient. In the process of mounting the Mylar sheet 40 and tearing off the Mylar sheet 40, there is a risk that the adhesive on the Mylar sheet 40 will enter the slot 21, and the adhesive covering the pin 22 will also affect the electrical connection between the memory and the pin 22, making the yield rate of the card holder 20 mounting process low.

[0074] Figure 6 Schematic diagram of the structure of setting Mylar sheet on the card seat Figure 2 .

[0075] See also Figure 6 As shown, the Mylar sheet 40 may deform and warp, and the warping of the Mylar sheet 40 may reduce the suction force between the suction terminal 12 and the Mylar sheet 40, and the card holder 20 may fall off before moving to the corresponding position on the corresponding circuit board 30. The warping of the Mylar sheet 40 may also affect the pressing effect of the suction terminal 12 on the card holder 20, so that the welding of the card holder 20 may have the risk of cold welding, further reducing the yield rate of the card holder 20 during the mounting process.

[0076] Based on this, an embodiment of the present application provides a mounting device that can improve the efficiency of the card holder mounting process and the mounting yield.

[0078] See also Figures 7 to 10As shown, the mounting device 100 provided in the embodiment of the present application includes a support base 110, a driving component 120 and a clamping component 130. The support base 110 is provided with a first movable channel 111, a second movable channel 112 and a receiving portion 113. The first movable channel 111 and the second movable channel 112 are symmetrically arranged on both sides of the receiving portion 113 along the first direction X. A part of the driving component 120 is located in the receiving portion 113. The clamping component 130 includes a first push rod 131 and a second push rod 132. The first push rod 131 is located in the first movable channel 111, and the second push rod 132 is located in the second movable channel 112. The driving component 120 can drive the first push rod 131 and the second push rod 132 to move away from each other along the first direction X, so that the first push rod 131 and the second push rod 132 are respectively abutted against the side walls 23 of the card base 20.

[0079] Specifically, the cross section of the support base 110 may be approximately rectangular. The support base 110 includes a first direction X and a second direction Y. The first direction X of the support base 110 is the first direction X of the card holder 20 , and the second direction Y is perpendicular to the first direction X.

[0080] Please continue to see Fig. 9 and Fig.10 As shown, the support seat 110 has a receiving portion 113, the cross section of which is also roughly rectangular, and the driving assembly 120 is located in the middle area of ​​the receiving portion 113 along the first direction X. The receiving portion 113 is symmetrically provided with a first moving channel 111 and a second moving channel 112 on both sides along the first direction X, and the first moving channel 111 and the second moving channel 112 both extend along the first direction X.

[0081] The clamping assembly 130 includes a first push rod 131 and a second push rod 132, both of which are long bars extending along the first direction X. The first push rod 131 is located in the first moving channel 111, and the second push rod 132 is located in the second moving channel 112. The end of the first push rod 131 facing the driving assembly 120 is the first end 131a, the end of the first push rod 131 away from the driving assembly 120 is the second end 131b, the end of the second push rod 132 facing the driving assembly 120 is the third end 132a, and the end of the second push rod 132 away from the driving assembly 120 is the fourth end 132b.

[0082] When the card base 20 needs to be mounted, the distance between the second end 131b of the first push rod 131 and the fourth end 132b of the second push rod 132 is made smaller than the distance between the two side walls 23 of the card base 20; then the mounting device 100 is placed above the card base 20, and the lower surface of the mounting device 100 is in contact with the upper surface of the card base 20; then the driving component 120 drives the first push rod 131 to move in the first moving channel 111, and drives the second push rod 132 to move in the second moving channel 112, and the first push rod 131 and the second push rod 132 move away from each other at the same time, so that the second end 131b of the first push rod 131 is moved away from each other. The fourth end 131b of the second push rod 132 abuts against the first side wall 23a of the card holder 20, and the second end 131b applies a first pressure to the first side wall 23a, and the first pressure can generate a friction force between the second end 131b and the first side wall 23a; the fourth end 132b of the second push rod 132 abuts against the second side wall 23b of the card holder 20, and the fourth end 132b applies a second pressure to the second side wall 23b, and the second pressure can generate a friction force between the fourth end 132b and the second side wall 23b; the mounting device 100 can clamp the card holder 20 by the friction force generated by the first pressure and the second pressure, and move the card holder 20 to the corresponding position on the circuit board 30.

[0083] In a possible implementation manner, a push plate 133 is disposed on each side of the first push rod 131 and the second push rod 132 facing away from each other, and the push plate 133 is used to abut against the side wall 23 of the card seat 20 .

[0084] Specifically, a first push plate 1331 is disposed on the second end 131b of the first push rod 131, and the cross-sectional area of ​​the first push plate 1331 is relatively large, so that the contact area between the first push plate 1331 and the first side wall 23a is relatively large, and thus the friction force between the first push plate 1331 and the first side wall 23a is relatively large. A second push plate 1332 is disposed on the fourth end 132b of the second push rod 132, and the cross-sectional area of ​​the second push plate 1332 is relatively large, so that the contact area between the second push plate 1332 and the second side wall 23b is relatively large, and thus the friction force between the second push plate 1332 and the second side wall 23b is relatively large, which can increase the reliability of the clamping assembly 130 clamping the card holder 20.

[0085] The mounting device 100 provided in the embodiment of the present application is provided with a support base 110, a driving assembly 120 and a clamping assembly 130. The support base 110 has a first moving channel 111, a second moving channel 112 and a receiving portion 113. The first moving channel 111 and the second moving channel 112 are symmetrically arranged on both sides of the receiving portion 113 along a first direction X. A part of the driving assembly 120 is located in the receiving portion 113. The clamping assembly 130 includes a first push rod 131 and a second push rod 132. The first push rod 131 is located in the first moving channel 111. 1, the second push rod 132 is located in the second moving channel 112; the driving assembly 120 can drive the first push rod 131 and the second push rod 132 to move away from each other along the first direction X, so that the first push rod 131 and the second push rod 132 are respectively in contact with the side wall 23 of the card holder 20, the pressure between the first push rod 131 and the side wall 23 can generate friction, and the pressure between the second push rod 132 and the side wall 23 can generate friction, and the mounting device 100 can clamp the card holder 20 by friction and move the card holder 20 to the corresponding position on the circuit board. In this way, the process of setting the Mylar sheet 40 on the card holder 20 can be omitted, thereby improving the efficiency of the mounting process of the card holder 20 and the yield of the mounting.

[0086] Next, the specific structure of the drive assembly is described.

[0087] Fig.11 for Fig.10 Enlarged view of point C in the middle; Fig.12 A schematic diagram of the structure of a driving component in a mounting device provided in an embodiment of the present application; Fig.13 This is a schematic diagram of the structure of the first push rod in the mounting device provided in an embodiment of the present application.

[0088] See also Figures 9 to 13 As shown, the driving assembly 120 includes a first driving part 121, and a first push rod 131 and a second push rod 132 are symmetrically arranged on both sides of the first driving part 121 along the first direction X; the size of the first driving part 121 along the second direction Y gradually increases from top to bottom to form a first inclined surface 1211 on both sides of the first driving part 121 along the first direction X, and the first push rod 131 and the second push rod 132 have a second inclined surface 134 on one side facing the first inclined surface 1211, and the second inclined surface 134 abuts against the first inclined surface 1211; when the first driving part 121 moves upward along the second direction Y, the first inclined surface 1211 exerts a force on the second inclined surface 134 to make the first push rod 131 and the second push rod 132 move away from each other along the first direction X.

[0089] In a possible implementation, the cross section of the first driving portion 121 may be an isosceles trapezoid, with the short side and the long side facing upward, and two first inclined surfaces 1211 formed on the two sides, one first inclined surface 1211 facing the first push rod 131, and the other first inclined surface 1211 facing the second push rod 132. The inclination angle of the second inclined surface 134 on the first push rod 131 and the second push rod 132 is the same as the inclination angle of the first inclined surface 1211, and the second inclined surface 134 abuts against the first inclined surface 1211.

[0090] Fig.14 This is a schematic diagram of a process in which a first driving unit in a mounting device provided in an embodiment of the present application drives a first push rod and a second push rod to move away from each other along a first direction. Fig.14 In the embodiment, the distance between the midpoints of the two second inclined surfaces 134 aligned along the second direction Y is taken as an example for description.

[0091] See also Fig.14 As shown, when the first driving portion 121 does not move, the spacing between the midpoints aligned along the second direction Y on the second inclined surface 134 is the first spacing D1, and as the first driving portion 121 moves upward along the second direction Y, the spacing between the two first inclined surfaces 1211 gradually increases, so that the first spacing D1 also gradually increases, and the first push rod 131 and the second push rod 132 are restricted in the first moving channel 111 and the second moving channel 112 along the second direction Y, the first push rod 131 and the second push rod 132 cannot move along the second direction Y, and the first push rod 131 and the second push rod 132 move away from each other along the first direction X.

[0092] By setting the first inclined surface 1211 along both sides of the first driving part 121, and setting the second inclined surface 134 abutting against the first inclined surface 1211 on the first push rod 131 and the second push rod 132, when the first driving part 121 moves upward along the second direction Y, the action force between the first inclined surface 1211 and the second inclined surface 134 can drive the first push rod 131 and the second push rod 132 to move away from each other, so that the process of the driving component 120 driving the first push rod 131 and the second push rod 132 to move away from each other is relatively simple.

[0093] Please continue to see Figures 9 to 12 As shown, a piston cylinder 114 is provided on the support seat 110, and the piston cylinder 114 is connected to the accommodating portion 113. The driving assembly 120 includes a piston 122, and the piston 122 is located in the piston cylinder 114. The first driving portion 121 is connected to the piston 122 and the first driving portion 121 is located below the piston 122 along the second direction Y; the driving assembly 120 also includes a vacuum pump (not shown in the figure), and the vacuum pump is used to extract air in the piston cylinder 114 so that the piston 122 moves upward along the second direction Y in the piston cylinder 114.

[0094] Specifically, the piston cylinder 114 can be installed on the support seat 110 through the first fastener 140, and the piston cylinder 114 forms a connected cavity with the accommodating portion 113. The piston 122 is located in the piston cylinder 114, and the piston 122 can be integrally formed with the first driving portion 121, and the piston 122 is located above the first driving portion 121 along the second direction Y.

[0095] When the first driving part 121 needs to move upward along the second direction Y, the vacuum pump extracts air in the piston cylinder 114, so that negative pressure is formed in the piston cylinder 114, and the piston 122 moves upward along the second direction Y under the action of the negative pressure, thereby driving the first driving part 121 to move upward along the second direction Y.

[0096] Please continue to see Figures 9 to 11 As shown, a sealing ring 150 may be provided between the piston 122 and the side wall of the piston cylinder 114 , thereby increasing the sealing performance between the piston 122 and the piston cylinder 114 .

[0097] After the mounting device 100 places the holder 20 on the circuit board 30 , the mounting device 100 needs to be removed from the holder 20 .

[0098] Next, the specific process of removing the mounting device 100 from the holder 20 is described.

[0100] Please continue to see Figures 9 to 12 as well as Fig.15 As shown, the second driving part 123 is arranged on both sides of the first driving part 121 along the first direction X, and the two second driving parts 123 have a third inclined surface 1231 on one side facing the first driving part 121, and the third inclined surface 1231 is parallel to the first inclined surface 1211; the first push rod 131 and the second push rod 132 have grooves 135, and the grooves 135 are arranged one-to-one with the second driving part 123, and the second driving part 123 is inserted in the grooves 135, and the side walls of the grooves 135 form a fourth inclined surface 1351, and the fourth inclined surface 1351 abuts against the third inclined surface 1231; when the piston 122 moves downward in the piston cylinder 114 along the second direction Y, the third inclined surface 1231 exerts a force on the fourth inclined surface 1351, so that the first push rod 131 and the second push rod 132 move toward each other along the first direction Y.

[0101] The second driving part 123 is also disposed below the piston 122 and connected to the piston 122 , and the two second driving parts 123 are symmetrically disposed on both sides of the first driving part 121 along the first direction X. The first push rod 131 and the second push rod 132 have grooves 135 , and the two second driving parts 123 are respectively inserted into the two grooves 135 .

[0102] The second driving portion 123 has a third inclined surface 1231 , and the two third inclined surfaces 1231 are respectively parallel to the two first inclined surfaces 1211 . The side wall of the groove 135 close to the first driving portion 121 has a fourth inclined surface 1351 , and the fourth inclined surface 1351 abuts against the third inclined surface 1231 .

[0103] Fig.16 This is a schematic diagram of a process in which a second driving unit in a mounting device provided in an embodiment of the present application drives a first push rod and a second push rod to move toward each other along a first direction. Fig.16 In the embodiment, the distance between the midpoints of the two fourth inclined surfaces 1351 aligned along the second direction Y is taken as an example for description.

[0104] See also Fig.16 As shown, when the second driving portion 123 does not move, the spacing between the midpoints of the two fourth inclined surfaces 1351 aligned along the second direction Y is the second spacing D2, and as the second driving portion 123 moves downward along the second direction Y, the spacing between the two third inclined surfaces 1231 gradually decreases, so that the second spacing D2 also gradually decreases, and the first push rod 131 and the second push rod 132 are restricted in the first moving channel 111 and the second moving channel 112 along the second direction Y, the first push rod 131 and the second push rod 132 cannot move along the second direction Y, and the first push rod 131 and the second push rod 132 move toward each other along the first direction X.

[0105] Please continue to see Figures 9 to 11 As shown, the driving assembly 120 further includes an elastic member 124 , which abuts between the piston 122 and the upper cover of the piston cylinder 114 ; the resilience of the elastic member 124 enables the piston 122 to move downward along the second direction Y in the piston cylinder 114 .

[0106] The elastic member 124 can be a spring or an elastic sleeve. One end of the elastic member 124 along the elastic force direction abuts against the upper surface of the piston 122, and the other end of the elastic member 124 along the elastic force direction abuts against the upper cover of the piston cylinder 114. When the vacuum pump extracts the air in the piston cylinder 114 to make the piston 122 move upward along the second direction Y, the elastic member 124 will be compressed, so that the elastic member 124 generates elastic force. When the vacuum pump stops extracting the air in the piston cylinder 114, the piston 122 moves downward under the action of the elastic force of the elastic member 124, thereby driving the second drive unit 123 to move downward. By providing the elastic member 124 to drive the second drive unit 123 to move downward along the second direction Y, the movement method of the second drive unit 123 is simple.

[0107] In a possible implementation manner, both the elastic member 124 and the piston 122 are made of magnetic materials, and the elastic member 124 and the piston 122 have the same magnetic properties.

[0108] The elastic member 124 and the piston 122 are made of materials with the same magnetic properties, and the driving force of the elastic member 124 on the piston 122 can be increased by utilizing the principle that like charges repel each other.

[0109] Next, the specific structure of the support base 110 will be described.

[0110] Please continue to see Fig. 9 and Fig.10 As shown, the support seat 110 includes an upper support seat 115 and a lower support seat 116 , the upper support seat 115 is connected to the lower support seat 116 , and the space between the upper support seat 115 and the lower support seat 116 forms a first moving channel 111 and a second moving channel 112 ; the piston cylinder 114 is connected to the upper support seat 115 .

[0111] The upper support seat 115 is covered on the lower support seat 116 , and the upper support seat 115 and the lower support seat 116 may be connected via a second fastener 160 , wherein the piston cylinder 114 is mounted on the upper support seat 115 via a first fastener 140 .

[0112] The distance between the upper support seat 115 and the lower support seat 116 along the second direction Y limits the size of the first moving channel 111 and the second moving channel 112 along the second direction Y.

[0113] A surface of the lower support seat 116 facing away from the upper support seat 115 is used to abut against the upper surface of the card seat 20 .

[0114] When the mounting device 100 moves the holder 20 to a corresponding position on the circuit board 30 , the side of the lower support seat 116 facing away from the upper support seat 115 applies slight pressure on the upper surface of the holder 20 so that the holder 20 is attached to the circuit board 30 through solder.
