[0002] In the prior art, a pallet cabinet is required for component loading. The components to be mounted are manually loaded into the mounting machine, and then the feed components are sent to the mounting machine for mounting using a conveyor belt. For example, in the FPC (Flexible Printed Circuit) industry, a limited number of mounted boards are usually placed in a pallet cabinet. After the operator manually loads the pallet cabinet into the mounting machine, the feed carrier is sent in via a conveyor belt. The mounting machine takes the material from the feed carrier and mounts it on the mounted board, and then sends it out via a conveyor belt after completion.

[0043] First embodiment

[0044] like Figure 1 As shown, the first embodiment of the present invention discloses an automatic placement device, comprising:

[0045] The mounting workbench 1 comprises a feeding area 11 for carrying feeding parts and a mounting area 12 for carrying mounted parts, wherein the feeding area 11 and the mounting area 12 are located on the same horizontal plane;

[0046] The upstream conveying unit 2 is connected to the mounting workbench 1 and is arranged upstream of the production line of the mounting workbench, and is used to convey the feeding parts and the mounted parts to the mounting workbench together;

[0047] The robot arm 3 is arranged above the mounting workbench 1, and the robot arm 3 takes materials from the feeding part to the mounted part for mounting.

[0048] Specifically, the automatic mounting equipment of the first embodiment of the present invention has a mounting workbench 1 for mounting electronic components such as FPCs, wherein the feeding area 11 and the mounting area 12 of the mounting workbench are located on the same horizontal plane, wherein the feeding area 11 carries the feeding parts conveyed from the upstream conveying part 2, and the mounting area 12 carries the mounted parts conveyed from the upstream conveying part 2 at the same time, and the feeding parts and the mounted parts are placed on the same horizontal plane of the mounting workbench 1, so that the robot arm 3 can take materials from the feeding parts to the mounted parts for mounting operations. Among them, in this embodiment, the feeding parts and the mounted parts can be merged in the upstream conveying part 2, so that the feeding parts and the mounted parts can be arranged side by side in a straight line on the same horizontal plane, and the feeding parts and the mounted parts are transferred to the downstream of the production line until they are transferred to the mounting workbench 1. In this way, through the merging and conveying action of the upstream conveying part 2, the feeding parts and the mounted parts can be carried together on the same horizontal plane as the mounting workbench 1, and there is no need for operators to manually place the mounted parts in the mounting part, nor is there any need to produce and store a large number of mounted parts in advance for use. Fully automated assembly line production can be realized, which greatly improves production efficiency, and also improves production quality to a certain extent, and has high practical value.

[0049] In this embodiment, if Figure 1As shown, the feed area 11 and the mounting area 12 of the mounting workbench 1 can be an integrally formed horizontal surface, or a segmented horizontal surface. For example, the feed area 11 and the mounting area 12 can be two segments of a horizontal surface arranged side by side in one row. Furthermore, the mounting workbench 1 of this embodiment can be configured as a bracket-type conveyor belt structure, such as Figure 1 As shown, the mounting workbench 1 is configured as an integrally connected hollow rail-type bracket, so that the two can form a stable in-line horizontal surface, and at the same time, it is convenient to produce a new downstream transfer of the feeding parts and the mounted parts together after the mounting is completed.

[0050] More specifically, the upstream conveying section 2 of the present embodiment includes: a confluence section 21, the confluence section 21 has a first placement table and a second placement table arranged in a row on the same horizontal surface, the first placement table and the second placement table respectively carry the feed parts and the mounted parts obtained from different directions upstream of the production line; a conveying section 22, the conveying section 22 is connected to the downstream of the confluence section 21, and is used to transport the feed parts on the first placement table and the mounted parts on the second placement table to the mounting workbench. The first placement table and the second placement table of the confluence section 21 can be independent components separated from each other. For example, the first placement table and the second placement table are configured as two supporting platforms that can be moved independently, so that the first placement table and the second placement table can pick up the feed parts and the mounted parts from different components, respectively, thereby increasing the flexibility and convenience of operation. Similar to the mounting workbench 1, the first placement table and the second placement table of the confluence section 21 can also be an integrally connected confluence bracket, such as Figure 1 As shown in the figure, the first placement platform and the second placement platform are configured as a hollow rail-type bracket connected in one piece. The first placement platform and the second placement platform are connected in one piece, so that the two can form a stable horizontal platform surface in a row, and the conveying part can transfer the first placement platform and the second placement platform to the downstream together.

[0051] The conveying part 22 of the upstream conveying part 2 mentioned above at least includes a traction member, a load-bearing device and a driving device, wherein the traction member is used to transmit traction force, and a conveyor belt, a traction chain or a steel wire rope may be adopted; the load-bearing device is used to hold parts and materials, such as a hopper, a bracket or a sling, etc.; the driving device provides power to the conveying part, and is generally composed of an electric motor, a reducer and a brake, etc.; in addition, the conveying part 22 may also include a tensioning device and a supporting member, and the tensioning device generally has two types: a screw type and a heavy hammer type, which can keep the traction member at a certain tension and verticality to ensure the normal operation of the conveying part; the supporting member is used to support the traction member or the load-bearing device, and rollers, rollers, etc. may be adopted. In this embodiment, the load-bearing device of the conveying part 22 may be adopted as follows: Figure 1 The transport bracket shown in .

[0052] Furthermore, the above-mentioned merging bracket and conveying bracket are both configured as hollow track-type brackets, and the merging bracket and the conveying bracket are integrally connected to form a conveyor-type merging conveying mechanism, which cooperates with the bracket-type conveyor belt structure of the loading workbench to present an automated assembly line production system. It can not only ensure that the feeding parts and the mounted parts are arranged in a row on the same table, but also facilitate the feeding parts and the mounted parts to be quickly and unobstructedly transferred to the mounting workbench 1 after they are arranged, which can maximize the production efficiency and ensure the high quality and speed of part mounting.

[0053] After the feed parts and the mounted parts are transferred to the horizontal surface of the mounting workbench 1, the robot arm 3 takes the materials from the feed parts to the mounted parts for mounting. Figure 2 As shown, in this embodiment, the robot arm 3 is installed on the combined work frame above the mounting workbench 1, and the combined work frame includes: a Y-axis slide 31, the Y-axis slide 31 drives the robot arm to move forward and backward along the Y-axis direction; an X-axis slide 32, the X-axis slide 32 is connected to the Y-axis slide and is used to install the robot arm 3, and the X-axis slide 32 drives the robot arm 3 to move left and right along the X-axis direction; a Z-axis lifting mechanism 33, the Z-axis lifting mechanism 33 is arranged on the X-axis slide 32, and is used to drive the robot arm 3 to move vertically along the Z-axis direction. Through the coordination of each module of the combined work frame, the robot arm 3 is controlled to move forward and backward, left and right, up and down in accordance with the preset program instructions, so as to complete the actions of taking materials from the feeding parts, moving the materials to the mounted parts, and mounting at the position where mounting is required. The robot arm 3 installed on the combined work frame coordinates with the mounting workbench 1 as a whole, ensuring that the mounting operation can be carried out quickly, efficiently and orderly.

[0054] In addition, it should be noted that Figure 3 As shown, in the automatic placement equipment of this embodiment, a precise positioning device 4 is further provided on the side of the placement workbench 1. The precise positioning device 4 plays a role similar to that of human eye observation and is used to precisely locate the placement position of the material, and cooperates with the robot arm 3 to place the material obtained from the feeding part at the predetermined position of the mounted part to ensure the accuracy of material placement.

[0055] The automatic placement device in this embodiment further includes an output unit 5, such as Figure 1 As shown in FIG. 1 , the output unit 5 is connected to the downstream of the mounting workbench 1 and is used to pick up the feed parts and the mounted parts that have been mounted from the mounting workbench 1 and transport them to the downstream production line. Figure 1As shown, the output unit 5 can be an independent conveying mechanism separated from the mounting workbench 1, or can be integrally connected to the mounting workbench 1. For example, the output unit 5 is configured as a conveyor belt integrally connected to the mounting workbench 1. More preferably, the output unit 5 can be configured as a conveyor bracket integrally connected to the mounting workbench 1 and the upstream conveying unit 2.

[0056] In summary, the feeding area and the mounting area of ​​the mounting workbench of the first embodiment of the present invention are located on the same horizontal plane, and cooperate with the upstream conveying part to convey the feeding parts and the mounted parts to the mounting workbench together, so that the feeding parts and the mounted parts can be placed on the same table for mounting operations. There is no need for operators to manually place the mounted parts, nor is there a need to produce and store a large number of mounted parts in advance for use. Fully automated assembly line production can be achieved, which greatly improves production efficiency and also improves production quality to a certain extent, and has high practical value.

[0057] Second embodiment

[0058] The second embodiment of the present invention discloses an automatic placement system, such as Figure 4 As shown, including:

[0059] The component conveying mechanism 10 is used to pick up and convey the feeding components and the mounted components from the upstream of the production line;

[0060] The automatic placement device 20 is arranged downstream of the component conveying mechanism, and receives the feeding components and the mounted components conveyed by the component conveying mechanism for placement. Specifically, Figure 1 As shown, the automatic placement equipment 20 includes: a placement workbench 1, including a feeding area 11 for carrying feeding parts and a placement area 12 for carrying mounted parts, wherein the feeding area 11 and the placement area 12 are located in the same horizontal plane; an upstream conveying part 2, connected to the placement workbench 1 and arranged upstream of the production line of the placement workbench, for conveying the feeding parts and the mounted parts to the placement workbench together; a robot arm 3, arranged above the placement workbench 1, and the robot arm 3 takes materials from the feeding parts to the mounted parts for placement.

[0061] Furthermore, the upstream conveying section 2 of the second embodiment of the present invention includes: a confluence section 21, the confluence section 21 has a first placement table and a second placement table arranged in a row on the same horizontal surface, the first placement table and the second placement table respectively carry the feed parts and the mounted parts obtained from different directions upstream of the production line; a conveying section 22, the conveying section 22 is connected to the downstream of the confluence section 21, and is used to transport the feed parts on the first placement table and the mounted parts on the second placement table to the mounting workbench. The first placement table and the second placement table of the confluence section 21 can be independent components separated from each other. For example, the first placement table and the second placement table are configured as two bearing platforms that can be moved independently, so that the first placement table and the second placement table can pick up the feed parts and the mounted parts from different components, respectively, thereby increasing the flexibility and convenience of operation. Similar to the mounting workbench 1, the first placement table and the second placement table of the confluence section 21 can also be an integrally connected confluence bracket, such as Figure 1 As shown in the figure, the first placement platform and the second placement platform are configured as a hollow rail-type bracket connected in one piece. The first placement platform and the second placement platform are connected in one piece, so that the two can form a stable horizontal platform surface in a row, and the conveying part can transfer the first placement platform and the second placement platform to the downstream together.

[0062] In this embodiment, the component conveying mechanism 10 includes a slideway located at a different horizontal plane from the confluence part 21, and a first lifting platform and a second lifting platform are installed on the slideway. At least one of the first lifting platform and the second lifting platform can move horizontally along the slideway, and both the first lifting platform and the second lifting platform can be lifted and lowered vertically. In the production process, for example, the first lifting platform picks up the feeding component from the upstream of the production line, and the second lifting platform picks up the mounted component from the upstream of the production line. The first lifting platform lifts vertically and / or moves horizontally along the slide rail to place the feeding component on the first placement platform, and the second lifting platform lifts vertically and / or moves horizontally along the slide rail to place the mounted component on the second lifting platform, so that the feeding component and the mounted component are merged and placed on the same platform surface in advance, and the components are obtained by relying on the upstream of the first lifting platform and the second lifting platform, so as to facilitate the flexible adjustment of the height of picking and placing, and the first lifting platform and the second lifting platform can move horizontally along the slide rail, so as to facilitate the flexible adjustment of the horizontal position of placement, thereby improving the flexibility and convenience of the production process.

[0063] Furthermore, the first lifting platform and / or the second lifting platform has a supporting shaft and a supporting platform, and the supporting platform can rotate 360 ​​degrees around the supporting shaft. During the production process, after the first lifting platform picks up the feeding parts from the upstream of the production line, its supporting platform rotates a certain angle around its supporting shaft, thereby adjusting the placement angle of the feeding parts, ensuring that the feeding parts are placed on the first placement platform at the most suitable angle; or after the second lifting platform picks up the mounted parts from the upstream of the production line, its supporting platform rotates a certain angle around its supporting shaft, thereby adjusting the placement angle of the mounted parts, ensuring that the mounted parts are placed on the second placement platform at the most suitable angle. The design of the supporting shaft and the supporting platform rotating around the supporting shaft facilitates the first lifting platform or the second lifting platform to flexibly adjust the picking or placement angle of the parts, increasing the flexibility and convenience of production.

[0064] As a preferred embodiment of this embodiment, the first placement table can be designed as a hollow track bracket structure, and the support shaft of the first lifting platform can pass through the hollow part of the first placement table to support its supporting platform to rise and fall vertically relative to the first placement table. After the first lifting platform is adjusted to a suitable vertical height and horizontal angle, the first lifting platform vertically drops below the bracket of the first placement table, thereby placing the feeding parts directly on the first placement table without the need for an additional conveying or picking mechanism; and / or the second placement table can also be designed as a hollow track bracket structure, and the support shaft of the second lifting platform can also pass through the hollow part of the second placement table to support its supporting platform to rise and fall vertically relative to the second placement table. In this way, after the second lifting platform is adjusted to a suitable vertical height and horizontal angle, the second lifting platform vertically drops below the bracket of the second placement table, thereby placing the mounted parts directly on the second placement table without the need for an additional conveying or picking mechanism, thereby greatly simplifying the mechanical structure, reducing the production process, and improving the production efficiency.

[0065] In this embodiment, the component conveying mechanism 10 also includes a conveyor table arranged upstream of the confluence section 21, and the conveyor table is used to carry and convey the feed components picked up from the upstream of the production line, so that the first lifting platform can pick up the feed components during vertical lifting. Specifically, the conveyor table can also be designed as a hollow track-type bracket structure, and the support shaft of the first lifting platform can pass through the conveyor table to support its supporting platform to vertically lift relative to the conveyor table. During the production process, after the conveyor table picks up the feed components, the first lifting platform moves along the slide rail to the same horizontal position as the conveyor table, and then the support shaft of the first lifting platform is raised to support its supporting platform to obtain the feed components while passing through the conveyor table, and then the first lifting platform moves horizontally along the slide rail to the downstream of the production line. Setting the conveyor table as a hollow track-type bracket structure facilitates the first lifting platform to directly obtain the feed components during vertical lifting without the need for additional conveying or picking mechanisms, thereby greatly simplifying the mechanical structure, reducing the production process, and improving the production efficiency.

[0066] Furthermore, the component conveying mechanism 10 also includes a gripping device for gripping the mounted components picked up from the upstream of the production line and placing them on the second lifting platform. Different from the existing manual operation to place the mounted components, this embodiment can rely on the gripping device to automatically pick up the mounted components, realize a fully automated production process, and improve production efficiency.

[0067] Furthermore, the automatic placement system of this embodiment further includes a downstream output unit 30, which is connected to the placement workbench 1 and is disposed downstream of the production line of the placement workbench 1, and transports the feed parts of the placement workbench 1 and the mounted parts that have been mounted to the downstream of the production line. The downstream output unit 30 includes a separation mechanism for separating the feed parts from the mounted parts that have been mounted. In this embodiment, the separation mechanism is composed of a third lifting platform and a support shaft supporting the third lifting platform. The third lifting platform can be composed of a part of the conveying bracket mentioned above, that is, a part of the conveying bracket is separated from the subsequent downstream conveying part, and the support shaft is connected below a part of the conveying bracket. In the production process, after the mounted parts and the feeding parts that have been mounted are output from the mounting workbench 1 in sequence, the mounted parts that have been mounted are transferred to the subsequent downstream conveying part, and the feeding parts are transferred to the third lifting platform. At this time, the support shaft pulls the third lifting platform to move in a direction different from the transfer direction of the downstream conveying part, thereby separating the feeding parts from the mounted parts that have been mounted. Preferably, the support shaft can be lifted vertically. When the mounted parts that have been mounted are transferred to the subsequent downstream conveying part, and the feeding parts are transferred to the third lifting platform, the support shaft first controls the third lifting platform to lift vertically upward or downward, and then the third lifting platform transports the feeding parts to a direction different from the transfer direction of the downstream conveying part, so as to achieve more accurate and rapid automatic control.

[0068] In summary, with the cooperation of the component conveying mechanism 10 and the automatic mounting equipment 20, this embodiment automatically obtains the feed components and the mounted components from the upstream of the production line, and relies on the confluence section to arrange the feed components and the mounted components in a row on the same horizontal plane in advance. There is no need for operators to manually place the mounted components in the mounting section, nor is there a need to produce and store a large number of mounted components in advance for use. Fully automated assembly line production can be achieved, which greatly improves production efficiency and also improves production quality to a certain extent.

[0069] Third embodiment

[0070] like Figure 5 As shown, the third embodiment of the present invention discloses an automatic placement process for placing materials using an automatic placement device, including:

[0071] Step S301, driving the upstream conveying unit 2 to convey the feeding parts and the mounted parts to the mounting workbench 1, so that the feeding parts and the mounted parts are arranged on the same horizontal plane;

[0072] Step S302, driving the robot arm 3 to take materials from the feeding part to the mounted part for mounting.

[0073] Specifically, Figure 6 As shown, first, the first placement table and the second placement table of the confluence part 21 of the upstream conveying part 2 respectively carry the feeding parts and the mounted parts. Since the first placement table and the second placement table are arranged in a row to form a horizontal surface, after the feeding parts and the mounted parts are placed on the first placement table and the second placement table of the confluence part 21 respectively, the feeding parts and the mounted parts can be arranged side by side in a straight line on the same horizontal plane. In step S301, the conveying part 22 of the upstream transmission part 2 is driven to convey the feeding parts and the mounted parts to the mounting workbench 1 together, wherein the feeding area 11 of the mounting workbench 1 carries the feeding parts, and the mounting area 12 of the mounting workbench 1 carries the mounted parts. The feeding area 11 and the mounting area 12 are located on the same horizontal plane, so that in step 302, the robot arm 3 takes the material from the feeding parts to the mounted parts for mounting operations. In this way, through the confluence and conveying action of the upstream conveying section 2, the feeding parts and the mounted parts can be carried together on the same horizontal plane of the mounting workbench 1. There is no need for operators to manually place the mounted parts in the mounting section, nor is there a need to produce and store a large number of mounted parts in advance for use. Fully automated assembly line production can be achieved, which greatly improves production efficiency and, to a certain extent, improves production quality, and has high practical value.

[0074] More specifically, Figure 7 As shown, in step 302, when the robot arm 3 performs the component placement operation, the following steps are performed:

[0075] Step 3021, identifying whether there is a carrier board placed on the mounting workbench, wherein the carrier board can hold the feeding parts and the mounted parts;

[0076] Step 3022, if a carrier board is put in, identify whether there is a carrier board with a mounted component identification;

[0077] Step 3023, if there is a carrier board with a mounted component identification, identify whether there is a carrier board with a supply component identification;

[0078] Step 3024, if there is a carrier with a feeding component identification, drive the robot arm to move to the feeding component to absorb the material;

[0079] Step 3025, identifying the position of the mounted component, and driving the robot arm to move to the mounted component for mounting;

[0080] Step 3026, determine whether the mounted component has been mounted. If it has been mounted, repeat steps 3021 to 3026; if it has not been mounted, repeat steps 3024 to 3026.

[0081] In step 3022, it is identified whether there is a carrier with a mounted component identification. If the mounted component identification is not identified, an abnormal processing is performed on the carrier of the mounted component; in step 3023, it is identified whether there is a carrier with a feed component identification. If the feed component identification is not identified, an abnormal processing is performed on the carrier of the feed component. The abnormal processing includes reloading the carrier, alarming, re-identification and other processing measures.
