Description

Technical Field

[0001] This application belongs to the field of receiving machine structure design, and specifically relates to an automatic batch receiving device. Background Technology

[0002] In the CSP packaging reflow oven soldering process, the receiving machine is often responsible for receiving the soldered materials and collecting a certain number of products together.

[0003] Traditional receiving machines can only initiate the receiving action and complete the unloading of materials when the material bin is full. However, different products are produced in different batches, and the number of products in each batch varies. This results in the receiving machine not receiving a receiving signal after completing a batch, allowing the next batch of products to still be conveyed, causing material mixing accidents. Alternatively, the receiving machine can be manually controlled to stop receiving products and forcibly complete the receiving action, but this can cause collisions between product carriers and also wastes manpower.

[0004] Therefore, it is desirable to have a technical solution to overcome or at least mitigate one of the aforementioned defects of the prior art. Utility Model Content

Therefore, they should not be construed as limiting the scope of protection of this application.

[0034] The following is in conjunction with the appendix Figure 1 This application will be described in further detail.

[0035] This application provides an automatic batch receiving device, including: a receiving platform 1, a lifting mechanism 2, a material carrier plate, a material box 3, a detection module 4, a pushing mechanism 5, a color mark sensor 6, and a controller.

[0036] Specifically, the receiving platform 1 has a two-layer structure, including an upper receiving platform and a lower receiving platform, such as... Figure 1 As shown (the support structure of receiving platform 1 is not fully shown), the upper receiving platform includes a first upper receiving section and a second upper receiving section from left to right. The first upper receiving section is equipped with a first conveying mechanism 11, which conveys from left to right and can convey empty material boxes 3 from left to right. The second upper receiving section is equipped with a second conveying mechanism 12, which conveys from right to left and can convey material carriers loaded with materials from right to left. The lower receiving platform is located below the first upper receiving section and is equipped with a third conveying mechanism 13, which conveys from right to left and can convey material boxes 3 loaded with materials from right to left. The lifting mechanism 2 is located between the first upper receiving section and the second upper receiving section, connecting the upper receiving platform and the lower receiving platform. The lifting mechanism 2 can transfer the material box 3 from the first conveying mechanism 11 of the upper receiving platform to the third conveying mechanism 13 of the lower receiving platform.

[0037] The second upper receiving section connects to the reflow oven. The material welded in the reflow oven is placed on the second conveying mechanism 12 via a material carrier plate. The second conveying mechanism 12 can transport the material carrier plate from right to left, i.e., towards the lifting mechanism 2. The material carrier plates include regular carrier plates and color-blocked carrier plates. The regular carrier plates are loaded with material, while the color-blocked carrier plates are used during batch closing and do not require loading. Empty material boxes 3 are placed on the first conveying mechanism 11 of the first upper receiving section. The empty material boxes 3 can be conveyed by the first conveying mechanism 11 to the lifting mechanism 2, where a material carrier plate is loaded. Then, the lifting mechanism 2 conveys the empty material boxes 3 to the third conveying mechanism 13.

[0038] Furthermore, the detection module 4 includes a first detection unit and a second detection unit, which are respectively located at both ends of the second upper receiving section. These units are used to detect the movement position of the material carrier plate. The first detection unit can detect the position signal when the material carrier plate is just placed in the second upper receiving section, and the second detection unit can detect the position signal when the material carrier plate is conveyed to the vicinity of the lifting mechanism 2. A pushing mechanism 5 is located on the second upper receiving section and is used to push the material carrier plate into the material box 3. A color mark sensor 6 is located on the second upper receiving section and is used to identify carrier plates of different colors.

[0039] In addition, the controller is used to control the start and stop of the first conveying mechanism 11, the second conveying mechanism 12, the third conveying mechanism 13, the lifting mechanism 2, and the pushing mechanism 5 based on the received detection module signal and color mark sensor signal.

[0040] In a preferred embodiment of this application, the first conveying mechanism 11 and the third conveying mechanism 13 for transporting the material box 3 are metal conveying mechanisms. The second conveying mechanism 12 for transporting the material carrier plate is a rubber conveying mechanism.

[0041] In a preferred embodiment of this application, the lifting mechanism 2 is a screw lifting mechanism, which mainly consists of a lifting platform, a screw, a sliding bearing, a drive motor, and a reducer. Preferably, a fourth conveying mechanism is provided on the lifting platform. The fourth conveying mechanism has two working states: forward rotation and reverse rotation, which is beneficial for the material box 3 to be conveyed between the first conveying mechanism 11 and the lifting mechanism 2, and between the lifting mechanism 2 and the third conveying mechanism 13. The lifting platform is connected to the screw via the sliding bearing, forming a mechanism that can move up and down. The drive motor is controlled by a controller. When the drive motor drives the reducer to rotate, the reducer transmits power to the screw, causing the screw to rotate. Since the sliding bearing between the screw and the lifting platform transmits power and displacement, the rotational motion of the screw is converted into the linear motion of the lifting platform, thereby achieving the lifting function. By controlling the rotation direction and speed of the screw, the lifting speed and position of the lifting platform can be precisely controlled.

[0042] In a preferred embodiment of this application, the material box 3 has multiple partitions arranged vertically. The lifting mechanism 2 controls the material box 3 to move downwards one partition layer at a time, loading material carriers sequentially from the bottom partition to the top partition. In this embodiment, a photoelectric sensor is preferably installed inside the top partition of the material box 3. The controller is also used to control the start and stop of the first conveying mechanism 11, the third conveying mechanism 13, and the lifting mechanism 2 based on the received photoelectric sensor signal. When the photoelectric sensor detects that there is a material carrier in the top partition of the material box 3, it indicates that all partitions in the material box 3 are full of material carriers. The photoelectric sensor transmits a signal to the controller, which activates the lifting mechanism 2 to lower the material box 3 to the lower receiving platform and controls the third conveying mechanism 13 to convey the full material box 3 to the left. When the lifting platform of the lifting mechanism 2 reaches the receiving position of the upper receiving platform, the first conveying mechanism 11 conveys the empty material box 3 to the lifting mechanism 2 for material loading.

[0043] In this embodiment, the first detection unit and the second detection unit of the detection module 4 are preferably pressure sensors.

[0044] In a preferred embodiment of this application, the pushing mechanism 5 includes a slide rail, a slider, a drive motor, and an elastic push rod. The slider slides along the slide rail under the drive of the drive motor. One end of the elastic push rod is mounted on the slider, and when pushing the material carrier plate, the elastic push rod has a predetermined angle with the plane of the second upper receiving section. When the material carrier plate moves from right to left on the second conveying mechanism 12, the end of the elastic push rod not connected to the slider is pressed against the second upper receiving section by the material carrier plate. After the material carrier plate moves past the pushing mechanism 5, under the action of elasticity, the elastic push rod returns to the position with a predetermined angle with the plane of the second upper receiving section, and under the drive of the slider, pushes the material carrier plate into the corresponding partition layer of the material box 3.

[0045] Advantageously, in this embodiment, the controller is equipped with manual operation buttons for controlling the start and stop of the first conveying mechanism 11, the second conveying mechanism 12, the third conveying mechanism 13, the lifting mechanism 2, and the pushing mechanism 5, so that manual intervention can be performed in special circumstances.

[0046] The automatic batch-closing receiving device of this application utilizes a color mark sensor 6 to pre-calibrate the color of the dissimilar color carrier plate. When batch closing is not required, materials are loaded using a regular carrier plate. When batch closing is required, a dissimilar color carrier plate that does not require loading is placed, and the color mark sensor 6 identifies the color of the dissimilar color carrier plate, completing the batch closing action. The specific batch closing process is as follows:

[0047] The controller controls the first conveying mechanism 11 to start working, and the empty material box 3 is conveyed along the first conveying mechanism 11 to the lifting mechanism 2.

[0048] After the reflow oven-welded material is loaded onto a conventional carrier plate, the carrier plate passes through a first detection unit. The first detection unit transmits a signal to a controller, which then activates a second conveying mechanism 12. The carrier plate is conveyed by the second conveying mechanism 12 towards the lifting mechanism 2. When the carrier plate reaches the opening of the material box 3 on the lifting mechanism 2, the second detection unit located below the carrier plate transmits a signal to the controller. The controller then activates a pushing mechanism 5. The slider of the pushing mechanism 5 moves along the slide rail and, upon contacting the edge of the carrier plate, pushes it into the partition layer of the material box 3. The controller then transmits a control signal to the lifting mechanism 2, causing the screw to rotate. The lifting platform moves downwards along the screw by one partition layer, preparing another empty partition layer in the material box 3 for material loading. This process is repeated multiple times.

[0049] When the photoelectric sensor detects that there is a material carrier plate in the uppermost partition layer of the material box 3, the photoelectric sensor transmits a signal to the controller. The controller controls the lifting mechanism 2 to transfer the material box 3 to the third conveying mechanism 13 on the lower receiving platform, and controls the third conveying mechanism 13 to transfer the full material box 3 to the left. After the operator receives the material box 3 loaded with material carrier plates from the lower receiving platform, he / she pulls out the material carrier plates from each partition layer in the material box 3, and the material on the material carrier plates is retained in the material box 3, thus completing the receiving process.

[0050] When batch closure is required, a different-colored carrier plate is manually placed. When the carrier plate passes over the color mark sensor 6, the color mark sensor 6 transmits a signal to the controller. After the pushing mechanism 5 pushes the carrier plate to the material box 3, the controller controls the lifting mechanism 2 to rotate the screw and transfer the material box 3 to the third conveying mechanism 13 on the lower receiving platform. The controller then controls the third conveying mechanism 13 to transfer the material box 3 containing the batch closure material to the left. After receiving this carrier plate, the receiving action is completed, and the batch closure is finished.

[0051] Furthermore, whenever a material box 3 is conveyed to the third conveying mechanism 13 of the lower receiving platform via the lifting mechanism 2, and the lifting platform of the lifting mechanism 2 moves to the receiving position between the first upper receiving section and the second upper receiving section, the empty material box 3 is conveyed to the lifting mechanism 2 via the first conveying mechanism 11. The bottommost partition layer inside the material box 3 is then prepared for material loading to carry out the next batch of receiving work.

[0052] The automatic batch-closing receiving device of this application places a different-colored carrier plate, distinct from the regular carrier plate, in the batch that needs to be batched. After the color mark sensor 6 identifies the different-colored carrier plate, it transmits a receiving signal to the controller to complete the receiving action, thereby completing the batch-closing task. This application can achieve intelligent control, greatly reducing the risk of product mixing and batch mixing, and lowering the probability of mixing accidents; it reduces operator intervention, greatly reducing the probability of accidents such as product carrier plate collisions and product appearance damage caused by manual receiving; it improves reflow oven welding efficiency, reduces labor costs, and reduces costs while increasing efficiency.

[0053] The above description is merely a specific embodiment of this application, but the scope of protection of this application is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
