Description

Technical Field

[0001] The present invention relates to the technical field of automatic workpiece line transfer, and in particular to a workpiece line transfer device. Background Art

[0002] In modern life, people have a huge demand for products such as smartphones, smartwatches, and laptops, and the market demand for electronic parts and components is also increasing. Circuit boards are one of the most important components in electronic products. They connect a group of related electronic devices to form a specific electronic circuit, making the circuit miniaturized and intuitive. They play a vital role in the mass production of fixed circuits and optimizing the layout of electrical appliances.

[0003] During the manufacturing process, circuit boards undergo both silkscreen printing and lamination. Silkscreen printing is used to print the symbols of various electronic components on the board, as well as to display necessary information such as socket orientation, high-voltage warnings, and label frames. Lamination, on the other hand, protects the board surface from scratches.

[0004] In the prior art, when a circuit board is processed by a screen printer and then transferred to the laminating process, manual unloading and loading operations are often required, which is a cumbersome process and requires a large amount of manpower. It also results in low utilization of the processing site and a messy process.

[0005] In addition, since the processing frequency of the silk-screen printing process cannot be effectively connected with the processing frequency of the laminating process, product stacking or lack of material may occur. Summary of the Invention

[0062] The present invention will be further described in detail below with reference to the accompanying drawings and examples. It will be understood that the specific embodiments described herein are intended only to illustrate the present invention and are not intended to limit the present invention. It should also be noted that, for ease of description, the accompanying drawings only illustrate portions relevant to the present invention, not all structures.

[0063] In the description of the present invention, unless otherwise expressly specified or limited, the terms "connected," "connected," and "fixed" should be understood in a broad sense. For example, they may refer to fixed connections, detachable connections, or integration; mechanical connections or electrical connections; direct connections or indirect connections through an intermediate medium; and internal communication between two components or interaction between two components. Those skilled in the art will understand the specific meanings of the above terms in the present invention in specific circumstances.

[0064] In the present invention, unless otherwise expressly specified or limited, a first feature being "above" or "below" a second feature may include the first and second features being in direct contact, or may include the first and second features being in contact not directly but through another feature between them. Furthermore, a first feature being "above," "above," and "above" a second feature may include the first feature being directly above or obliquely above the second feature, or may simply mean that the first feature is higher in level than the second feature. A first feature being "below," "below," and "below" a second feature may include the first feature being directly below or obliquely below the second feature, or may simply mean that the first feature is lower in level than the second feature.

[0065] In the description of this embodiment, the terms "upper," "lower," "right," and other orientations or positional relationships are based on the orientations or positional relationships shown in the accompanying drawings and are intended solely for ease of description and simplified operation. They do not indicate or imply that the devices or components referred to must have, be constructed, or operate in a specific orientation. Therefore, they should not be construed as limitations on the present invention. Furthermore, the terms "first" and "second" are used solely for descriptive purposes and have no special meanings.

[0066] This embodiment provides a workpiece transfer device, which is located between the laminating machine and the screen printing machine and is used to connect the laminating machine and the screen printing machine, and transfer the workpiece processed in the laminating machine to the screen printing machine to save labor costs and ensure processing efficiency.

[0067] Since the laminating machine and the screen printing machine are separate equipment, their production rhythms are different. If they cannot be effectively connected, the processing speed of the laminating machine will be high and the processing speed of the screen printing machine will be low. That is, when the laminating process is faster than the screen printing process, the product will have overlapping materials, and when the laminating process is faster than the screen printing process, there will be a phenomenon of no material, thus affecting the processing efficiency.

[0068] In order to solve the above problems, Figures 1 and 2As shown, the workpiece transfer equipment provided in this embodiment includes a transport buffer device 1000, a pick-up robot 3000, and a manual transfer conveyor line 2000. When the processing speed of the laminating process is lower than that of the silk-screen process, the pick-up robot 3000 can automatically remove the workpiece from the silk-screen process and transfer it to the transport buffer device 1000, without manual loading, thus saving manpower. The transport buffer device 1000 can transport the workpiece to a designated location and then stack and cache it. When the workpiece is stacked to a designated number of layers, it is transported to the silk-screen process. Optionally, the number of layers is 20. Stacking the workpieces processed from the laminating process can give the silk-screen process a certain buffer time, thereby effectively connecting the laminating process with the silk-screen process. When the processing speed of the laminating process is slower than that of the silk-screen printing process, the workpieces produced by the laminating process cannot meet the processing requirements of the silk-screen printing process. In order to ensure processing efficiency, the stacked workpieces after lamination are manually placed on the manual transfer conveyor line 2000. The manual transfer conveyor line 2000 can transfer the workpieces one by one to the transport buffer device 1000. The transport buffer device 1000 transports the workpieces to the silk-screen printing process, thereby meeting the effective connection between the laminating process and the silk-screen printing process and ensuring processing efficiency. In addition, the transport buffer device 1000 can transport the workpiece directly to the silk-screen printing process to realize automatic unloading, without manual unloading, saving manpower. In addition, the workpiece transfer line equipment can efficiently use the processing site, and will not cause chaos in the processing site due to manual loading and unloading, saving processing procedures.

[0069] Furthermore, if Figure 2 As shown, there are two transport buffers 1000, one on each side of the retrieval robot 3000. The retrieval robot 3000 can alternately discharge materials into the two transport buffers 1000, thereby extending the buffering time. Of course, the retrieval robot 3000 can also discharge materials into only one of the transport buffers 1000. The specific operation can be selected based on the actual processing rate between the laminating process and the screen printing process. This makes the workpiece transfer line equipment applicable to a wider range of situations.

[0070] In order to prevent the workpiece from being affected by external impurities, flying dust, etc. during transportation, Figure 1 As shown, the workpiece transfer line equipment also includes a dustproof rack 4000. The transport buffer device 1000, the retrieval robot 3000, and the manual transfer conveyor line 2000 are all installed within the dustproof rack 4000, thereby isolating the workpieces from the outside world and improving the cleanliness of the entire process. It is worth noting that to facilitate manual loading, the discharge end of the manual transfer conveyor line 2000 is located outside the dustproof rack 4000.

[0071] Next, combine Figures 1 and 2 The picking robot 3000 is described as follows: Figures 1 and 2As shown, the retrieval robot 3000 is located at the end of the transport buffer device 1000, and can accurately identify the position of the workpiece after the laminating process is completed, thereby improving the problem of irregular grabbing of the workpiece from the carrier of the laminating process. In addition, the grabbing end of the retrieval robot 3000 adopts a suction cup type suction head, which can not only ensure the stability of the workpiece during transportation but also will not damage the workpiece. The retrieval robot 3000 can rotate 0°~90°~0° or 0°~-90°~0° to unload the workpiece from the laminating process to the transport buffer device 1000. As for the specific structure of the retrieval robot 3000, it is a common structure in this technical field. Any robot in the prior art that can rotate 0°~90°~0° or 0°~-90°~0° can be used, and this embodiment is not specifically limited here.

[0072] Next, combine Figures 3 to 8 The transport buffer device 1000 will be described.

[0073] like Figure 3 The transport buffer device 1000 comprises a lifting and transporting mechanism 1100 and a buffering mechanism 1200. The lifting and transporting mechanism 1100 is capable of moving workpieces from the high workstation where the retrieval robot 3000 deposits materials to a low workstation and then transporting them to the next workstation. Since the retrieval robot 3000 can utilize any existing technology, the retrieval robot 3000 can deposit materials at different locations. To accommodate these different deposit locations, the lifting and transporting mechanism 1100 can accommodate and transport workpieces at different heights. This facilitates procurement of the retrieval robot 3000 and reduces procurement costs. The buffering mechanism 1200, located at the workstation below the lifting and transporting mechanism 1100, stacks and buffers the workpieces. Once the workpieces have accumulated to a specified number of layers, they are transported to the laminating process. This not only provides a time buffer when the laminating process is faster than the screen printing process, ensuring a seamless transition between the two processes, but also enables automated workpiece unloading, saving manpower and reducing labor costs.

[0074] Specifically, if Figure 4 and Figure 5 As shown, the lifting and transporting mechanism 1100 includes a transport platform 1110, a conveyor assembly 1120, and a lifting assembly 1130. The transport platform 1110 extends from the retrieval robot 3000 to the buffer mechanism 1200. The conveyor assembly 1120 is disposed on the transport platform 1110. The lifting assembly 1130 is disposed in the center of the conveyor assembly 1120 and is located at the unloading station of the retrieval robot 3000. The lifting assembly 1130 can move the workpiece from the unloading station of the retrieval robot 3000 to abut against the conveyor assembly 1120. The conveyor assembly 1120 can then transport the workpiece to the buffer mechanism 1200, making operation convenient.

[0075] Furthermore, if Figure 4 As shown, the transmission assembly includes a driving member 1121, a driving pulley 1122, a driven pulley 1123, and a conveyor belt 1124. The driving member 1121 is disposed on a transport platform 1110. The driving pulley 1122 is rotatably disposed at one end of the transport platform 1110 and connected to the output end of the driving member 1121. The driving member 1121 can provide rotational power for the driving pulley 1122. The driven pulley 1123 is rotatably disposed at the other end of the transport platform 1110. The conveyor belt 1124 is respectively engaged with the driving pulley 1122 and the driven pulley 1123 and abuts against a workpiece. The rotation of the driving pulley 1122 drives the engaged conveyor belt 1124 to move, thereby driving the workpiece abutting the conveyor belt 1124 to move along with the driving pulley. At the same time, the conveyor belt 1124 drives the driven pulley 1123 to rotate. Since the driving pulley 1122 and the driven pulley 1123 are respectively located at the two ends of the extension direction of the transport platform 1110, the entire conveyor belt 1124 runs through the entire length of the transport platform 1110, which can more fully realize the transportation of the workpiece.

[0076] Furthermore, if Figure 4 As shown, there are two combinations of conveyor belts 1124, driving pulleys 1122, and driven pulleys 1123, which are located on both sides of the inside of the transport platform 1110. The two driving pulleys 1122 are connected by a driving shaft, and the two driven pulleys 1123 are connected by a driven shaft, thereby realizing the synchronous movement of the two sets of conveyor belts 1124 and sprocket combinations driven by a driving member 1121, thereby making the workpieces in contact with the two conveyor belts 1124 more stable during transportation.

[0077] As an optional solution, in order to make the structure of the transmission component 1120 more compact, as Figure 4 As shown, the transmission assembly 1120 also includes a transmission member 1125, one end of which is connected to the driving member 1121 and the other end is connected to the driving shaft, which can transmit the power of the driving member 1121 to the driving shaft, so that the driving shaft rotates, thereby driving the two driving pulleys 1122 to move synchronously. The transmission member 1125 can make the driving member 1121 located below the transport platform 1110 and parallel to the transmission assembly 1120, without having to be located outside the transport platform 1110 and coaxial with the driving shaft, thereby making the structure of the transmission assembly more compact and occupying a small area. Optionally, the transmission member 1125 can be composed of two meshing gears, or a combination of a belt and a pulley, as long as it can transmit power, this embodiment is not specifically limited here.

[0078] like Figure 5As shown, the lifting assembly 1130 includes an abutment plate 1131, a lifting column 1132, a slide 1133, and a driving cylinder 1134. The slide 1133 is fixedly mounted in the dustproof frame 4000. The lifting column 1132 is disposed within the slide 1133 and can move up and down along the slide 1133. The driving cylinder 1134 is disposed in the center of the slide 1133. The output end of the driving cylinder 1134 passes through the slide 1133 and is connected to the abutment plate 1131. The upper end surface of the lifting column 1132 is connected to the bottom surface of the abutment plate 1131, and the upper surface of the abutment plate 1131 abuts the workpiece. The output end of the driving cylinder 1134 can drive the abutment plate 1131 to rise and fall. During the ascent and descent of the abutment plate 1131, the movement of the lifting column 1132 along the slide 1133 can ensure smoother movement of the abutment plate 1131.

[0079] As an alternative, Figure 5 As shown, the lifting assembly 1130 also includes a guide column 1135, which has a through hole in the center. The guide column 1135 is passed through and fixed on the slide 1133, and the lifting column 1132 is passed through the guide column 1135. Since the guide column 1135 is relatively long, it can provide better guiding effect for the lifting column 1132 and increase the stability of the movement of the lifting column 1132.

[0080] As an alternative, Figure 5 As shown, there are multiple lifting columns 1132, and the multiple lifting columns 1132 are spaced apart and arrayed below the abutment plate 1131, thereby increasing the stability of the movement of the abutment plate 1131. It can be understood that the lifting columns 1132 and the guide columns 1135 are arranged in a one-to-one correspondence.

[0081] like Figure 6 As shown, the cache mechanism 1200 includes a cache rack 1210, a conveying assembly 1220, and a stacking assembly 1230. The cache rack 1210 is fixedly mounted on the dustproof frame 4000 and is located at the next workstation of the lifting and transporting mechanism 1100. The conveying assembly 1220 is mounted on the cache rack 1210 and can transport the workpieces. The stacking assembly 1230 is mounted on the cache rack 1210 and can lift the workpieces and stack them. When the workpieces are transported from the lifting and transporting mechanism 1100 to the cache rack 1210, the conveying assembly 1220 can transport the workpieces until they are aligned with the stacking assembly 1230. The stacking assembly 1230 can stack the workpieces, thereby achieving workpiece caching. When the workpieces are stacked to a specified height, the conveying assembly 1220 can transport the stacked workpieces to the silk-screen printing process, making operation convenient.

[0082] Specifically, if Figures 6 to 8As shown, the stacking assembly 1230 includes a lifting assembly 1231 and two sets of support assemblies 1232 . The lifting assembly 1231 is located in the center of the conveying assembly 1220 and can lift the workpiece located on the conveying assembly 1220 . There is a support assembly 1232 on each side of the cache rack 1210. The two groups of support assemblies 1232 can move toward each other to abut against the lifted workpiece, so that the workpiece is maintained at a certain height. At this time, the jacking assembly 1231 descends, and the conveying assembly 1220 continues to transport the workpiece toward the jacking assembly 1231. The jacking assembly 1231 rises again to lift the workpiece to abut against the previous workpiece, and the two groups of support assemblies 1232 move backwards to realize the stacking of the workpieces. After the jacking assembly 1231 lifts the stacked workpiece to a certain height, the two groups of support assemblies 1232 move toward each other again to support the stacked workpieces. This cycle repeats until the workpieces are stacked to a specified number of layers. The jacking assembly 1231 rises to abut against the bottom workpiece and drives the stacked workpiece down to the conveying assembly 1220. The operation is simple.

[0083] like Figures 7 and 8 As shown, the lifting assembly 1231 includes a lifting plate 12312 and a lifting drive 12311. The drive 12311 is disposed on the buffer rack 1210 and is located in the center of the conveying assembly 1220. The lifting plate 12312 can abut against the workpiece and is disposed at the output end of the lifting drive 12311. The output end of the lifting drive 12311 can drive the lifting plate 12312 to rise and fall to lift and lower the workpiece. Optionally, the lifting drive 12311 is a reciprocating cylinder. Of course, in other embodiments, it can also be another structure as long as it can provide power for the lifting plate 12312 to rise and fall. This embodiment does not make specific limitations here.

[0084] like Figures 7 and 8 As shown, the support assembly 1232 includes a support plate 12321 and a telescopic drive member 12322, wherein the telescopic drive member 12322 is arranged on the outside of the buffer rack 1210, and the support plate 12321 is arranged at the output end of the telescopic drive member 12322. The telescopic drive member 12322 can drive the support plate 12321 to move toward or away from the buffer rack 1210. The support plate 12321 can abut against the workpiece and support the weight of the stacked workpieces, with a simple structure and low cost. Optionally, the telescopic drive member 12322 is a telescopic cylinder. Of course, in other embodiments, it can also be another structure as long as it can provide telescopic power for the support plate 12321. This embodiment does not make specific limitations here.

[0085] like Figures 7 and 8 As shown, the structure of the conveying component 1220 is the same as that of the transmission component 1120, and will not be repeated here.

[0086] Next, combine Figures 9 and 10The manual transfer conveyor line 2000 will be described.

[0087] like Figure 9 As described, the manual transfer conveyor line 2000 includes a conveyor frame 2100, a transmission component 2200, a discharge component 2300 and a line transfer robot 2400, wherein the conveyor frame 2100 is located above the transport buffer device 1000 and is perpendicular to the transport buffer device 1000, the transmission component 2200 is arranged on the conveyor frame 2100, the discharge component 2300 is arranged at the end of the conveyor frame 2100 and is located on the outside of the dustproof frame 4000, the stacked workpieces are manually placed on the discharge component 2300, the discharge component 2300 can place the stacked workpieces one by one on the transmission component 2200, the transmission component 2200 can transport the workpiece to the line transfer robot 2400, the line transfer robot 2400 can remove the workpiece on the transmission component 2200 to the transport buffer device 1000, and the operation is convenient.

[0088] Specifically, if Figure 10 As shown, the rotary robot 2400 includes a rotary frame 2410, a sliding drive member 2440, a slide 2420, and a lifting clamping assembly 2430, wherein the sliding drive member 2440 is arranged on the rotary frame 2410, the slide 2420 is connected to the output end of the sliding drive member 2440, and the slide 2420 is slidably arranged on the rotary frame 2410. The lifting clamping assembly 2430 can clamp and release the workpiece and can drive the workpiece to rise and fall. The slide 2420 can drive the lifting clamping assembly 2430 to move along the rotary frame 2410, so that the lifting clamping assembly 2430 can align with the position of the workpiece, thereby accurately clamping the workpiece and driving the workpiece to rise, and then move with the slide 2420 to align with the transport buffer device 1000. After the lifting clamping assembly 2430 drives the workpiece to fall, it releases the workpiece so that the workpiece can abut against the lifting transport mechanism 1100, which is convenient to operate. Optionally, a slide groove is provided on the slide 2420, and a slide rail is provided on the turntable 2410. The slide groove and the slide rail cooperate to enable the slide 2420 to slide on the turntable 2410, which has a simple structure and low cost. Alternatively, the slide 2420 is provided with multiple slide grooves, and the turntable 2410 is provided with multiple slide rails corresponding thereto, so that the slide 2420 slides more smoothly. Optionally, the sliding drive member 2440 is a reciprocating cylinder, and as long as it can drive the slide 2420 to slide along the turntable 2410, this embodiment does not make any specific restrictions.

[0089] Furthermore, if Figure 10As shown, the lifting and clamping assembly 2430 includes a lifting power member 2431, a telescopic power member 2432 and a clamping plate 2433, wherein the lifting power member 2431 is fixedly arranged on the slide 2420, and the telescopic power member 2432 is arranged at the output end of the lifting power member 2431, and both sides of the telescopic power member 2432 can be extended or retracted at the same time, and a clamping plate 2433 is provided at the output end on both sides of the telescopic power member 2432. The telescopic power member 2432 can clamp or loosen the workpiece, and the lifting power member 2431 can drive the telescopic power member 2432 to rise and fall, thereby driving the workpiece to rise and fall, with a simple structure and easy operation. Optionally, the lifting power member 2431 is a telescopic cylinder. Of course, in other embodiments, it can also be other structures as long as it can provide power for the telescopic power member 2432 to rise and fall. This embodiment does not make specific restrictions. Optionally, the telescopic power member 2432 is a double-headed telescopic cylinder. Of course, in other embodiments, it can also be other structures as long as it can clamp and release the workpiece. This embodiment does not make any specific limitations.

[0090] like Figure 9 As shown, the structure and principle of the transmission assembly 2200 are identical to those of the conveyor assembly 1120 and will not be further described here. The structure of the discharge assembly 2300 is identical to that of the stacking assembly 1230 and will not be further described here. However, it should be noted that while the stacking assembly 1230 stacks workpieces, the discharge assembly 2300 discharges the stacked workpieces one by one, operating in the opposite manner to the stacking assembly 1230.

[0091] Furthermore, if Figure 2 and Figure 9 As shown, there are two transfer robots 2400, and one transfer robot 2400 is provided on the outside of each transport buffer device 1000. The two transfer robots 2400 can transport the workpieces to the corresponding transport buffer devices 1000 at the same time, and the transfer speed is faster at this time. Of course, one of the transfer robots can also transport the workpiece toward the corresponding transport buffer device 1000, and the transfer speed is slower at this time. As for whether the two transfer robots 2400 transfer at the same time or only one of them transfers, it needs to be determined according to the processing speed of the laminating process and the silk-screen printing process. This ensures a good connection between the laminating process and the silk-screen printing process, and ensures processing efficiency.

[0092] Obviously, the above embodiments of the present invention are merely examples for the purpose of clearly illustrating the present invention and are not intended to limit the embodiments of the present invention. A person skilled in the art would be able to make various obvious changes, readjustments, and substitutions without departing from the scope of protection of the present invention. It is not necessary and impossible to enumerate all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention shall be included within the scope of protection of the claims of the present invention.
