Description

Technical Field

[0001] This utility model relates to the field of chip mounter technology, and in particular to a chip mounter and its feeding mechanism. Background Technology

[0002] As the core equipment of the surface mount technology (SMT) production line, the automatic placement machine undertakes the key task of high-speed and high-precision placement of electronic components, and the performance of its feeding device directly affects the overall production efficiency.

[0003] In related technologies, the feeding device usually adopts a whole-section conveyor belt structure. When the whole-section conveyor belt corresponds to two mounting stations, it is easy to encounter the problem that the substrates of the two mounting stations cannot arrive at the same time. That is, when one substrate arrives at the mounting station on the conveyor belt, the other substrate has not arrived. At this time, the machine head corresponding to the substrate that has not arrived cannot work, resulting in a decrease in production efficiency. Utility Model Content

The first conveyor belt passes around the guide member from one side of the support member and extends to the opposite side of the support member. The adjusting member is detachably connected to the support member to adjust the position of the guide member relative to the support member, thereby adjusting the tension of the first conveyor belt.

[0011] In one embodiment, the support includes a platform and a base. In a second direction, the base is connected to opposite sides of the platform. The base has a mounting groove extending along the feeding direction. The first adjustment component includes a fastener passing through the adjustment member and the mounting groove.

[0012] In one embodiment, the feeding mechanism includes a traction component, which includes a third drive member connected to the support member, a mounting platform linked to the output end of the third drive member, a switching component connected to the mounting platform, and a clamping component linked to the output end of the switching component. The clamping component is further away from the first conveyor belt than the second conveyor belt. The switching component is used to switch between a first working state and a second working state. In the first working state, the switching component drives the clamping component away from the conveyor belt along a first direction and stops it. The first conveyor belt and the second conveyor belt are used to move the rigid plate along the feeding direction. In the second working state, the switching component drives the clamping component closer to the conveyor belt along the first direction. The clamping component is used to clamp or release the flexible plate. The third drive member drives the mounting platform, the switching component, and the clamping component to reciprocate along the feeding direction.

[0013] In one embodiment, the feeding mechanism includes guide wheels rotatably connected to the support member. The support member is provided with guide wheels on both sides along the feeding direction. In the first working state, the guide wheels are used to roll into contact with the rigid plate to limit the movement range of the rigid plate in the second direction.

[0014] In one embodiment, the feeding mechanism includes a limiting plate detachably connected to the edge of the support member. The limiting plate covers the edge of the first conveyor belt and is spaced apart from the edge of the first conveyor belt to form a first limiting groove. The limiting plate covers the edge of the second conveyor belt and is spaced apart from the edge of the second conveyor belt to form a second limiting groove. In a first working state, the thickness of the rigid plate is greater than the height of the first limiting groove and the second limiting groove. The limiting plate is used to limit the movement range of the rigid plate in a second direction. The second direction and the first direction are perpendicular to the feeding direction. In a second working state, the third driving member pulls the flexible plate along the feeding direction in the first limiting groove and the second limiting groove through the clamping assembly.

The first drive member and the first conveyor belt are respectively located on the support member, and the support member has a first mounting area corresponding to the first conveyor belt. The second conveyor mechanism includes a second drive member and a second conveyor belt linked to the second drive member. The second drive member and the second conveyor belt are respectively located on the support member, and the support member has a second mounting area corresponding to the second conveyor belt. The second mounting area and the first mounting area are spaced apart along the feeding direction. This feeding mechanism allows the first and second conveyor mechanisms to transport substrates independently. When a substrate arrives at the first mounting area on the first conveyor belt, the machine head can perform mounting processing on the substrate in the first mounting area. The continued transport of another substrate on the second conveyor belt or its positioning in the second mounting area does not affect the processing in the first mounting area. In other words, the processing in the first and second mounting areas can be more independent, improving the efficiency of equipment production. Attached Figure Description

[0030] It should be understood that the terms "length," "width," "top," "bottom," "front," "rear," "left," "right," "vertical," "horizontal," "upper," "lower," "external," and "internal" refer to the orientation or positioning relationship in the accompanying drawings to facilitate understanding of the invention, but do not limit the actual location or orientation of the invention. Therefore, the above terms should not be construed as limiting the actual location of the various elements of the invention.

[0031] It should be understood that the terms "first," "second," "an," "a," and "one" in the following description refer to "at least one" or "one or more" in the embodiments. In particular, the term "a" may refer to "one" in one embodiment and "more than one" in another embodiment. Therefore, the above terms should not be construed as limiting the actual number of elements of the present invention.

[0032] To facilitate understanding of this utility model, a more complete description will be given below with reference to the accompanying drawings. Preferred embodiments of this utility model are shown in the drawings. However, this utility model can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided to provide a more thorough and complete understanding of the disclosure of this utility model.

[0033] refer to Figure 1 This utility model discloses a pick and place machine 10, which is an automated equipment for electronic manufacturing. Its core function is to accurately place surface mount components onto designated positions on a substrate through a high-precision and high-efficiency placement process.

[0034] like Figure 1 As shown, the pick and place machine 10 includes a frame 110 and a feeding mechanism 120, which is connected to the frame 110. The frame 110 is used to support the feeding mechanism 120 and other mechanisms such as the machine head.

[0035] Furthermore, the pick-and-place machine 10 may include two or more sets of feeding mechanisms 120. The feeding methods of the two sets of feeding mechanisms 120 are arranged in parallel, and each set of feeding mechanisms 120 may correspond to two or more placement areas for placement processing by the machine head. Taking the pick-and-place machine 10 including two sets of feeding mechanisms 120, each set of feeding mechanisms 120 including two placement areas as an example, the entire pick-and-place machine 10 is configured with 4 placement areas. The two sets of feeding mechanisms 120 can work in parallel. Parallel work can be understood as the two sets of feeding mechanisms 120 working independently without interfering with each other, which can significantly improve the placement efficiency compared to a single feeding assembly 120.

[0036] refer to Figure 2In some embodiments, the feeding mechanism 120 includes a first conveying mechanism 121, a second conveying mechanism 122, and a support member 123. The support member 123 is connected to the frame 110, and the first conveying mechanism 121 and the second conveying mechanism 122 are respectively disposed on the support member 123. In some embodiments, the first conveying mechanism 121 may include a first driving member 1211 and a first conveyor belt 1212 linked with the first driving member 1211. The first driving member 1211 and the first conveyor belt 1212 are respectively disposed on the support member 123, and the support member 123 has a first mounting area 123a corresponding to the first conveyor belt 1212. The second conveying mechanism 122 may include a second driving member 1221 and a second conveyor belt 1222 linked with the second driving member 1221. The second driving member 1221 and the second conveyor belt 1222 are respectively disposed on the support member 123, and the support member 123 has a second mounting area 123b corresponding to the second conveyor belt 1222. The second mounting area 123b and the first mounting area 123a are spaced apart along the feeding direction. The first driving member 1211 and the second driving member 1221 may be motors. Because the first driving member 1211 and the second driving member 1221 of the first conveying mechanism 121 and the first conveying mechanism 1212 are independently configured, the first conveyor belt 1212 and the second conveyor belt 1222 can independently transport the substrate by controlling the rotation speed of the first driving member 1211 and the second driving member 1221. For example, in the working state, the substrate moves along the feeding direction. The first conveyor belt 1212 and the second conveyor belt 1222 cooperate to transport the substrate to the second mounting area 123b. If the substrate is in place in the second mounting area 123b, the conveyor belt of the second conveying mechanism 122 stops transporting, and the conveyor belt of the first conveying mechanism 121 continues to transport the substrate until the substrate in the first mounting area 123a is in place, and then all transport stops.

[0037] In existing technologies, substrates can be broadly classified into flexible boards and rigid boards. Flexible boards, also known as flexible circuit boards, are typically thinner and less rigid. FPC (Flexible Printed Circuit) is a typical example of a flexible board. Before mounting, continuous flexible boards are usually rolled up. During mounting, the continuous flexible boards are gradually unrolled and transferred to the mounting area of ​​the pick-and-place machine 10. After surface mount components are mounted on the flexible boards in the mounting area, they can be pulled out of the mounting area, allowing the mounting area to be covered by unmounted flexible boards for continued mounting operations, thus achieving continuous mounting. After surface mount components are mounted, the continuous flexible boards can also extend from the pick-and-place machine 10 and be rolled up for easy handling and transportation.

[0038] Common rigid boards include printed circuit boards (PCBs), which are much more rigid than flexible boards and are generally manufactured using a segmented surface mount component (SUP) process. That is, individual rigid boards are transferred to the mounting area of ​​the pick-and-place machine 10 for mounting. After one rigid board is mounted, it can be removed and another unmounted rigid board can be placed in its place, thus completing the mounting process of rigid boards.

[0039] Also refer to Figure 2 and reference Figure 3 The feeding mechanism 120 includes a traction component 124 connected to the support member 123. The traction component 124 includes a third drive member 1241 connected to the support member 123, a mounting platform 1242 linked to the output end of the third drive member 1241, a switching component 1243 connected to the mounting platform 1242, and a clamping component 1244 linked to the output end of the switching component 1243. The clamping component 1244 is further away from the first conveyor belt 1212 than the second conveyor belt 1222. The switching component 1243 is used to switch between a first working state and a second working state. In the first working state, the switching component 1243 drives the clamping component 1244 away from the second conveyor belt 1222 along a first direction and stops it. The first conveyor belt 1212 and the second conveyor belt 1222 are used to move the rigid board along the feeding direction. In the second working state, the switching component 1243 drives the clamping component 1244 to move closer to the second conveyor belt 1222 along the first direction. The clamping component 1244 is used to clamp or release the flexible board. The third driving member 1241 drives the mounting table 1242, the switching component 1243, and the clamping component 1244 to reciprocate along the feeding direction to realize the movement of the flexible board in the feeding direction. The function of the feeding mechanism 120 in switching between the first and second working states allows one feeding mechanism 120 to transport two different types of boards, namely flexible boards and rigid boards. One feeding mechanism 120 can replace two feeding mechanisms 120 for transporting different types of boards, reducing the equipment purchase cost for manufacturers using the pick-and-place machine 10. In some embodiments, the third driving member 1241 can be a stepper motor, the motor shaft of which is the output end. It can drive the mounting platform 1242 and the switching component 1243 connected to the mounting platform 1242 to reciprocate along the feeding direction through a conveyor structure.

[0040] Furthermore, in some embodiments, the switching component 1243 includes a fourth drive member 12431 mounted on the mounting platform 1242, and the clamping component 1244 includes a clamping plate 12441 and a clamping seat 12442 disposed opposite to each other. The clamping seat 12442 is linked to the output end of the fourth drive member 12431 so that the fourth drive member 12431 drives the clamping component 12444 as a whole away from or towards the second conveyor belt 1222. The clamping component 1244 may also include a fifth drive member 12443 connected to the clamping seat 12442. The clamping plate 12441 is linked to the output end of the fifth drive member 12443 so that the fifth drive member 12443 drives the clamping plate 12441 to rise and fall relative to the clamping seat 12442, thereby clamping or releasing the flexible board. In some embodiments, the clamping seat 12442 may be in the shape of a long strip and may extend along a second direction from one end of the support 123 across the second conveyor belt 1222 to the opposite end of the support 123.

[0041] Furthermore, either the fourth driving component 12431 or the fifth driving component 12443 can be a pneumatic cylinder or a hydraulic cylinder, with the piston rod of the pneumatic or hydraulic cylinder serving as the output end. In the first operating state, the switching component 1243 drives the clamping component 1244 to move away from the second conveyor belt 1222 along the first direction and then stops, avoiding interference with the transport of the rigid board. In the second operating state, the switching component 1243 drives the clamping component 1244 to move closer to the second conveyor belt 1222 along the first direction, and the clamping plate 12441 reciprocates in the first direction to clamp or release the flexible board.

[0042] refer to Figure 4 and Figure 5 In some embodiments, the feeding mechanism 120 includes a limiting plate 125 detachably connected to the edge of the support member 123. The limiting plate 125 covers the edge of the first conveyor belt 1212 and is spaced apart from the edge of the first conveyor belt 1212 to form a first limiting groove 125a. The limiting plate 125 covers the edge of the second conveyor belt 1222 and is spaced apart from the edge of the second conveyor belt 1222 to form a second limiting groove 125b. In the first working state, the thickness of the rigid board is greater than the height of the first limiting groove 125a and the second limiting groove 125b. The limiting plate 125 is used to limit the movement range of the rigid board in the second direction. The second direction and the first direction are perpendicular to the feeding direction. In the second working state, the third driving member 1241 pulls the flexible board in the first limiting groove 125a and the second limiting groove 125b along the feeding direction through the clamping assembly 1244. At the same time, it also prevents the flexible board from shifting due to lack of constraint during the pulling process, so that the pick and place machine 10 may shift or fail to work properly during placement.

[0043] Continue to refer to Figure 4 and Figure 5 The first conveyor belt 1212 is provided with multiple first air holes 12121, and the second conveyor belt 1222 is provided with multiple second air holes 12221. (See also...) Figure 6 The support member 123 is provided with a first ventilation groove 1233 corresponding to the first mounting area 123a for communicating with the first air hole 12121, and the support member 123 is provided with a second ventilation groove (not shown) corresponding to the second mounting area 123b for communicating with the first air hole 12121. The second ventilation groove has the same structure and function as the first ventilation groove 1233. In the second working state, the clamping flexible board of the clamping assembly 1244 moves along the feeding direction. When it moves to the first mounting area 123a, the first air hole 12121 and the first ventilation groove 1233 cooperate to form a negative pressure, which picks up and fixes the flexible board on the surface of the first conveyor belt 1212. When the flexible board moves to the second mounting area 123b, the second air hole 12221 and the second ventilation groove cooperate to form a negative pressure, which picks up and fixes the flexible board on the surface of the second conveyor belt 1222, avoiding placement failure or placement position deviation caused by the movement of the flexible board during placement, and improving the placement efficiency and accuracy of the pick-and-place machine 10.

[0044] Furthermore, all the first air holes 12121 are arranged in an array on the first conveyor belt 1212, and all the second air holes 12221 are arranged in an array on the second conveyor belt 1222. However, the arrangement is not limited to this arrangement. As long as the first air holes 12121 can cooperate with the first ventilation groove 1233 and the second air holes 12221 can cooperate with the second ventilation groove to achieve the corresponding functions, it is acceptable.

[0045] Furthermore, taking the first air hole 12121 and the first ventilation groove 1233 as examples, the diameter of the first air hole 12121 is much smaller than the width of the first ventilation groove 1233. For example, the ratio of the diameter of the first air hole 12121 to the width of the first ventilation groove 1233 is 1:10 to 1:20. When the first air hole 12121 and the first ventilation groove 1233 work together, part of the first air hole 12121 of the first conveyor belt 1212 covers the first ventilation groove 1233, and the first ventilation groove 1233 is connected to multiple first air holes 12121. The first ventilation groove 1233 is correspondingly set with the first air hole 12121, which can reduce the alignment accuracy requirement of the first air hole 12121. That is, the first ventilation groove 1233 with a relatively large area is used to connect multiple first air holes 12121, thereby avoiding the need to open the first air hole 1212 on the support member 123 and require the first air holes 1212 on the two parts to be precisely aligned to meet the adsorption requirements of the flexible board, thereby reducing the difficulty of processing and control.

[0046] When the feeding mechanism 120 transports the rigid board, the traction component 124 switches to the first working state through the switching component 1243. After the clamping component 1244 moves away from the second conveyor belt 1222 in the first direction, the first conveyor belt 1212 and the second conveyor belt 1222 begin to cooperate in transporting the rigid board to the corresponding first mounting area 123a and second mounting area 123b.

[0047] refer to Figure 3 and Figure 7 In some embodiments, the feeding mechanism 120 includes an adjustment assembly 126 connected to the support member 123. The adjustment assembly 126 includes a first adjustment assembly 1261 and a second adjustment assembly 1262. The first adjustment assembly 1261 includes an adjusting member 12611 and a guide member 12612 connected to the adjusting member 12611. The guide member 12612 is rotatably connected to the adjusting member 12611 and is connected to the end of the support member 123 away from the second conveyor belt 1222. 212 extends from one side of the support member 123, around the guide member 12612, and to the opposite side of the support member 123. The adjusting member 12611 is detachably connected to the support member 123 to adjust the position of the guide member 12612 relative to the support member 123, thereby adjusting the tension of the first conveyor belt 1212. The second adjusting component 1262 has a similar structure and function to the first adjusting component 1261, except that the second adjusting component 1262 is located at the end of the support member 123 furthest from the first conveyor belt 1212. By adjusting the tension of the first conveyor belt 1212 and the second conveyor belt 1222 respectively using the first adjusting component 1261 and the second adjusting component 1262, appropriate tension ensures the normal operation of the first conveyor belt 1212 and the second conveyor belt 1222, avoids slippage due to insufficient tension, and thus guarantees stable power transmission.

[0048] Simultaneously combined Figure 2 In some embodiments, the support member 123 includes a platform 1231 and a base 1232. In the second direction, the base 1232 is connected to opposite sides of the platform 1231, and the base 1232 has a mounting groove 12321 extending along the feeding direction. Taking the first adjusting component 1261 as an example, it includes a fastener 12613 passing through the adjusting component 12611 and the mounting groove 12321. The fastener 12613 is used to realize the detachable connection between the adjusting component 12611 and the base 1232, and to adjust the relative position between the adjusting component 12611 and the base 1232. After determining the relative position, the adjusting component 12611 is fixed so that the adjusting component 12611 will not loosen or move when the feeding mechanism 120 is running, thereby realizing the tensioning of the first conveyor belt 1212.

[0049] refer to Figure 4 and Figure 5In some embodiments, the feeding mechanism 120 includes a first blocking component 127 and a second blocking component 128 disposed on the platform 1231 or base 1232 of the support member 123. The first blocking component 127 is connected to the edge of the support member 123 and is used to limit the rigid board to the first mounting area 123a in the first working state; the second blocking component 128 is connected to the edge of the support member 123 and is used to limit the rigid board to the second mounting area 123b in the first working state.

[0050] Taking the first blocking component 127 as an example, it may include a driving source and a blocking component 1271 linked to the output end of the driving source. The driving source may be a cylinder, and the piston rod of the cylinder is the output end, which can push the blocking component 1271 of the first blocking component 127 to move in the second direction to abut against the rigid plate, so that the rigid plate no longer moves forward.

[0051] In some embodiments, the feeding mechanism 120 includes a first detection component 129 and a second detection component 1210 connected to the support member 123. The first detection component 129 is disposed corresponding to the first conveyor belt 1212, and the second detection component 1210 is disposed corresponding to the second conveyor belt 1222. The first detection component 129 and the second detection component 1210 can be photoelectric sensors used to detect whether the rigid plate has passed through the position, so as to control the working state of the first blocking component 127 and the second blocking component 128.

[0052] In the first working state, the first conveyor belt 1212 and the second conveyor belt 1222 work together to transport the rigid board to the second mounting area 123b. When the second detection component 1210 detects that the rigid board has arrived, it triggers the second blocking component 128 to intercept the rigid board at the current position. After interception, the second conveyor belt 1222 stops rotating, while the first conveyor belt 1212 continues to run. Until the first detection component 129 also detects the rigid board, it triggers the first blocking component 127 to block the movement of the rigid board, and the first conveyor belt 1212 also stops transporting. This process is repeated to ensure that the transported rigid board stays in the corresponding first mounting area 123a and second mounting area 123b.

[0053] In some embodiments, the feeding mechanism 120 may further include guide wheels 1211 rotatably connected to the platform 1231 or the base 1232 of the support member 123. The support member 123 may be provided with guide wheels 1211 on both sides along the feeding direction. In the first working state, the guide wheels 1211 are used to roll contact with the hard plate to limit the movement range of the hard plate in the second direction, and at the same time reduce the frictional resistance of the hard plate when it is conveyed along the feeding direction.
