Description

Technical Field

[0001] This disclosure relates to the technical field of SMT placement apparatus, and in particular to a circuit board blanking structure and an SMT placement apparatus. Background Technology

[0002] SMT (Surface Mount Technology) placement equipment is a device installed after a dispensing machine or screen printer to accurately place surface mount components onto the corresponding positions on the surface of a circuit board that has been pre-printed with solder paste or adhesive. SMT placement equipment is widely used in automotive electronics, consumer electronics, communication equipment, machinery, medical equipment, and aerospace industries. An SMT placement equipment consists of a main body and a circuit board unloading structure, which is connected to the main body and is used to unload the circuit board.

[0003] The circuit board unloading structure of the related technology includes a conveyor belt assembly and a receiving assembly. The receiving assembly is set at the discharge end of the conveyor belt assembly. The conveyor belt assembly is used to transport the circuit board into the receiving assembly to complete the unloading process of the circuit board, such as Chinese patent with patent number CN202220368610.7.

[0004] However, since the conveyor belt assembly is used to transport the circuit board to the receiving assembly so that the circuit board can directly contact the conveyor belt assembly, that is, the circuit board can directly contact the conveyor belt body, and the conveyor belt body is generally a rubber conveyor belt structure, which makes the conveyor belt body have a certain degree of stickiness, making it easier for the circuit board to adhere to the conveyor belt body, which is not convenient for the circuit board unloading process. As a result, the circuit board unloading structure is less convenient for unloading the circuit board. Utility Model Content

[0005] The purpose of this disclosure is to overcome the shortcomings of the prior art and provide a circuit board blanking structure and SMT placement device with better convenience for blanking circuit boards.

[0006] The purpose of this disclosure is achieved through the following technical solution:

[0007] A circuit board cutting structure for connecting to the main body of the device includes:

[0008] A structural body for connecting to the device body, the structural body having a first mounting groove and a second mounting groove;

[0009] The rotating assembly includes a driving roller and a driven roller. The driving roller is located in the first mounting groove and is rotatably connected to the main structure. The driving roller has multiple first connecting ring grooves, which are spaced apart and each first connecting ring groove communicates with the first mounting groove. The driven roller is located in the second mounting groove and is rotatably connected to the main structure. The driven roller has multiple second connecting ring grooves, which are spaced apart and each second connecting ring groove communicates with the second mounting groove.

[0010] Multiple conveyor lines, each conveyor line is used to convey circuit boards, each conveyor line is wrapped around and passed through the corresponding first connecting ring groove and the corresponding second connecting ring groove, each conveyor line is rotatably connected to the driving roller and the driven roller respectively, and the outer peripheral wall of each conveyor line is provided with an anti-stick coating layer.

[0011] A drive mechanism is connected to the main body of the structure. The power output end of the drive mechanism is connected to the drive roller. The drive mechanism is used to drive the drive roller to rotate relative to the main body of the structure, so that the drive roller drives the driven roller to rotate relative to the main body of the structure through each of the conveyor lines. Each of the conveyor lines rotates around the circumference of the main body of the structure along the rotation direction of the drive roller.

[0012] In one embodiment, the main structure is further provided with a third mounting groove, and the rotating assembly further includes an intermediate roller body. The intermediate roller body is located in the third mounting groove and is rotatably connected to the main structure. The intermediate roller body is provided with a plurality of third connecting ring grooves, which are spaced apart. Each third connecting ring groove communicates with the third mounting groove. Each conveyor line body is also passed through the corresponding third connecting ring groove and is rotatably connected to the intermediate roller body, so that the drive roller drives the intermediate roller body to rotate relative to the main structure body through each conveyor line body.

[0013] In one embodiment, the intermediate roller body is a one-piece molded structure.

[0014] In one embodiment, a mounting bracket is provided at the bottom of the main structure, the mounting bracket being used to connect to the main body of the device, and the mounting bracket being located between the first mounting groove and the second mounting groove.

[0015] In one embodiment, the driving roller is a one-piece molded structure; the driven roller is a one-piece molded structure.

[0016] In one embodiment, the non-stick coating is a Teflon coating structure.

[0017] In one embodiment, each of the conveyor lines is a carbon-plastic wire structure, a steel wire structure, or a braided wire structure.

[0018] In one embodiment, the driving mechanism includes a drive motor, a mounting base, and a belt drive assembly. The drive motor is mounted on the mounting base, which is connected to the main structure. The belt drive assembly is connected to the power output end of the drive motor and the drive roller, respectively, so that the drive motor drives the drive roller to rotate relative to the main structure through the belt drive assembly.

[0019] In one embodiment, the belt drive assembly includes a drive pulley, a transmission belt, and a driven pulley. The drive pulley is mounted on the power shaft of the drive motor, the driven pulley is sleeved on the drive roller, and the transmission belt is sleeved on the drive pulley and the driven pulley respectively.

[0020] An SMT placement apparatus includes a main body and a circuit board unloading structure as described in any of the above embodiments, wherein the circuit board unloading structure is connected to the main body.

[0021] Compared with the prior art, this disclosure has at least the following advantages:

[0022] 1. Since each conveyor line is used to transport circuit boards, multiple conveyor lines work together to support the circuit boards, placing the circuit boards above the main structure. Each conveyor line is positioned between the circuit board and the main structure. When the circuit board first enters the circuit board unloading structure, it is located at one end of the main structure, adjacent to the driven roller. Then, the drive mechanism drives the driving roller to rotate relative to the main structure. Each conveyor line is rotatably connected to both the driving and driven rollers, causing the driving roller to drive the driven roller to rotate relative to the main structure through each conveyor line. Simultaneously, each conveyor line... The conveyor belts rotate around the main structure along the rotation direction of the drive roller, causing the circuit board to move relative to the main structure under the action of each conveyor belt. This allows each conveyor belt to transport the circuit board along the extension direction of the main structure, and multiple conveyor belts work together to transport the circuit board from one end of the main structure to the other end. At this time, the circuit board is positioned near the drive roller, and multiple conveyor belts work together to output the circuit board from the drive roller, so that the circuit board is separated from each conveyor belt and enters the receiving frame, thus completing the unloading process of the circuit board by the circuit board unloading structure.

[0023] 2. Due to the combined action of multiple conveyor lines, the circuit board is transported from one end of the main structure to the other end. The circuit board is then output from the drive roller and enters the receiving frame for unloading. Each conveyor line directly contacts the circuit board. Each conveyor line has an anti-stick coating on its outer periphery, ensuring direct contact between the coating and the circuit board. The anti-stick coating has excellent non-stick properties, making it difficult for the circuit board to adhere to the conveyor line. This solves the problem of circuit boards easily adhering to the conveyor belt in existing technologies. The anti-stick coating makes it difficult for each conveyor line to stick to the circuit board, facilitating unloading and improving the overall ease of unloading the circuit board.

[0034] like Figures 1 to 6 As shown, in one embodiment, the circuit board cutting structure 10 is used to connect with the device body.

[0035] Furthermore, the circuit board unloading structure 10 includes a main body 100, a rotating assembly 200, multiple conveyor lines 300, and a drive mechanism 400. The main body 100 is used to connect with the main body of the device, and the main body 100 has a first mounting groove 110 and a second mounting groove 120. The rotating assembly 200 includes a drive roller 210 and a driven roller 220. The drive roller 210 is located in the first mounting groove 110 and is rotatably connected to the main body 100. The drive roller 210 has multiple first connecting ring grooves 211, which are spaced apart, and each first connecting ring groove 211 communicates with the first mounting groove 110. The driven roller 220 is located in the second mounting groove 120 and is rotatably connected to the main body 100. The driven roller 220 has multiple second connecting ring grooves 221, which are spaced apart, and each second connecting ring groove 221 communicates with the first mounting groove 110. A second connecting ring groove 221 is connected to a second mounting groove 120; each conveyor line 300 is used to convey circuit boards, and each conveyor line 300 is arranged around and passes through the corresponding first connecting ring groove 211 and the corresponding second connecting ring groove 221. Each conveyor line 300 is rotatably connected to the driving roller 210 and the driven roller 220 respectively. The outer peripheral wall of each conveyor line 300 is provided with an anti-stick coating layer 310; the drive mechanism 400 is connected to the main body 100, and the power output end of the drive mechanism 400 is connected to the driving roller 210. The drive mechanism 400 is used to drive the driving roller 210 to rotate relative to the main body 100, so that the driving roller 210 drives the driven roller 220 to rotate relative to the main body 100 through each conveyor line 300. Each conveyor line 300 rotates around the circumference of the main body 100 along the rotation direction of the driving roller 210.

[0036] In this embodiment, each conveyor line 300 is used to convey a circuit board, so that multiple conveyor lines 300 work together to support the circuit board, so that the circuit board is located above the main structure 100, and each conveyor line 300 is located between the circuit board and the main structure 100. Each conveyor line 300 has an anti-stick coating layer 310 on its outer peripheral wall, so that the anti-stick coating layer 310 is formed and covered on the outer peripheral wall of each conveyor line 300.

[0037] In the aforementioned circuit board unloading structure 10, each conveyor line 300 is used to transport the circuit board, so that multiple conveyor lines 300 work together to support the circuit board, placing the circuit board above the main structure 100. Each conveyor line 300 is positioned between the circuit board and the main structure 100. When the circuit board first enters the circuit board unloading structure 10, it is located at one end of the main structure 100, adjacent to the driven roller 220. Then, the drive mechanism 400 drives the driving roller 210 to rotate relative to the main structure 100. Each conveyor line 300 is rotatably connected to both the driving roller 210 and the driven roller 220, allowing the driving roller 210 to drive the driven roller 220 relative to the main structure 100 via each conveyor line 300. The circuit board rotates 0, and at the same time, each conveyor line 300 rotates around the circumference of the main structure 100 along the rotation direction of the drive roller 210. This causes the circuit board to move relative to the main structure 100 under the action of each conveyor line 300, so that each conveyor line 300 conveys the circuit board along the extension direction of the main structure 100. This allows multiple conveyor lines 300 to work together to convey the circuit board from one end of the main structure 100 to the other end. At this time, the circuit board is positioned adjacent to the drive roller 210, so that multiple conveyor lines 300 work together to output the circuit board from the drive roller 210, so that the circuit board separates from each conveyor line 300 and enters the receiving frame, so that the circuit board unloading structure 10 completes the unloading process of the circuit board.

[0038] Multiple conveyor lines 300 work together to transport the circuit board from one end of the main structure 100 to the other end, and then output the circuit board from the drive roller 210 so that the circuit board enters the receiving frame to complete the unloading process. Each conveyor line 300 is in direct contact with the circuit board, and each conveyor line 300 has an anti-stick coating layer 310 on its outer peripheral wall, so that the anti-stick coating layer 310 is formed and covers the outer periphery of each conveyor line 300. The non-stick coating layer 310 of each conveyor line 300 is in direct contact with the circuit board. The non-stick coating layer 310 has good non-stick properties, making it difficult for the circuit board to adhere to each conveyor line 300. This solves the problem that the circuit board is easy to adhere to the conveyor belt in the prior art. Under the action of the corresponding non-stick coating layer 310, each conveyor line 300 is less likely to stick to the circuit board, which is beneficial to the unloading of the circuit board. As a result, the unloading structure 10 of the circuit board is more convenient for unloading the circuit board.

[0039] like Figure 1As shown, in one embodiment, the main body 100 is further provided with a third mounting groove 130, and the rotating component 200 further includes an intermediate roller body 230. The intermediate roller body 230 is located in the third mounting groove 130 and is rotatably connected to the main body 100. The intermediate roller body 230 is provided with a plurality of third connecting ring grooves 231, which are spaced apart. Each third connecting ring groove 231 communicates with the third mounting groove 130. Each conveyor line 300 is also passed through the corresponding third connecting ring groove 231 and is rotatably connected to the intermediate roller body 230, so that the drive roller 210 drives the intermediate roller body 230 to rotate relative to the main body 100 through each conveyor line 300.

[0040] In one embodiment, the intermediate roller body 230 is a one-piece molded structure, which makes the intermediate roller body 230 have high structural strength.

[0041] like Figure 2 As shown, in one embodiment, a mounting bracket 140 is provided at the bottom of the main body 100. The mounting bracket 140 is used to connect with the device body and is located between the first mounting groove 110 and the second mounting groove 120.

[0042] In one embodiment, the driving roller 210 is a one-piece molded structure, which makes the driving roller 210 have high structural strength; the driven roller 220 is a one-piece molded structure, which makes the driven roller 220 have high structural strength.

[0043] In one embodiment, the anti-stick coating 310 is a Teflon coating structure. The Teflon coating structure has good non-stick properties, which makes the anti-stick coating 310 have good non-stick properties. This makes it difficult for each conveyor line 300 to stick to the circuit board under the action of the corresponding anti-stick coating 310, which is beneficial to the unloading process of the circuit board.

[0044] In one embodiment, each conveyor line 300 is a carbon-plastic wire structure, a steel wire structure, or a braided wire structure, which makes each conveyor line 300 have high structural strength.

[0045] like Figures 1 to 6 As shown, in one embodiment, the drive mechanism 400 includes a drive motor 410, a mounting base 420, and a belt drive assembly 430. The drive motor 410 is mounted on the mounting base 420, which is connected to the main body 100. The belt drive assembly 430 is connected to the power output end of the drive motor 410 and the drive roller 210, respectively, so that the drive motor 410 drives the drive roller 210 to rotate relative to the main body 100 through the belt drive assembly 430, thereby improving the transmission reliability between the drive motor 410 and the drive roller 210.

[0046] like Figures 1 to 6As shown, in one embodiment, the belt drive assembly 430 includes a drive pulley 431, a transmission belt 432, and a driven pulley 433. The drive pulley 431 is mounted on the power shaft of the drive motor 410, the driven pulley 433 is sleeved on the drive roller 210, and the transmission belt 432 is respectively sleeved on the drive pulley 431 and the driven pulley 433, which improves the transmission reliability between the drive motor 410 and the drive roller 210.

[0047] This disclosure also provides an SMT placement apparatus, including an apparatus body and a circuit board unloading structure 10 of any of the above embodiments, wherein the circuit board unloading structure 10 is connected to the apparatus body.

[0048] Compared with the prior art, this disclosure has at least the following advantages:

[0049] 1. Since each conveyor line 300 is used to convey circuit boards, multiple conveyor lines 300 work together to support the circuit boards, so that the circuit boards are located above the main structure 100, and each conveyor line 300 is located between the circuit boards and the main structure 100. When the circuit board just enters the circuit board unloading structure 10, the circuit board is located at one end of the main structure 100. At this time, the circuit board is adjacent to the driven roller 220. Then, the drive mechanism 400 drives the drive roller 210 to rotate relative to the main structure 100. Each conveyor line 300 is rotatably connected to both the drive roller 210 and the driven roller 220, so that the drive roller 210 drives the driven roller 220 to rotate relative to the main structure 100 through each conveyor line 300. Each conveyor line 300 rotates around the main structure 100 in the direction of rotation of the drive roller 210, causing the circuit board to move relative to the main structure 100 under the action of each conveyor line 300. This allows each conveyor line 300 to transport the circuit board along the extension direction of the main structure 100, and multiple conveyor lines 300 work together to transport the circuit board from one end of the main structure 100 to the other end. At this time, the circuit board is positioned near the drive roller 210, and multiple conveyor lines 300 work together to output the circuit board from the drive roller 210, so that the circuit board separates from each conveyor line 300 and enters the receiving frame, thus completing the unloading process of the circuit board by the circuit board unloading structure 10.

[0050] 2. Due to the combined action of multiple conveyor lines 300, the circuit board is transported from one end of the main structure 100 to the other end. This allows the circuit board to be output from the drive roller 210 and enter the receiving frame, completing the unloading process. Each conveyor line 300 is in direct contact with the circuit board. Each conveyor line 300 has an anti-stick coating layer 310 on its outer peripheral wall, ensuring the anti-stick coating layer 310 covers and forms the outer surface of each conveyor line 300. The surrounding wall ensures that the anti-stick coating layer 310 of each conveyor line 300 is in direct contact with the circuit board. The anti-stick coating layer 310 has good non-stick properties, making it difficult for the circuit board to adhere to each conveyor line 300. This solves the problem in the prior art that the circuit board is easy to adhere to the conveyor belt. Under the action of the corresponding anti-stick coating layer 310, each conveyor line 300 is less likely to stick to the circuit board, which is beneficial for the unloading of the circuit board. As a result, the unloading structure 10 of the circuit board is more convenient for unloading the circuit board.

[0051] The embodiments described above are merely illustrative of several implementations of this disclosure, and while the descriptions are specific and detailed, they should not be construed as limiting the scope of the disclosed patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this disclosure, and these all fall within the protection scope of this disclosure. Therefore, the protection scope of this patent should be determined by the appended claims.
