Description

Technical Field

[0001] This invention relates to an integrated loading and unloading machine, and more particularly to an integrated loading and unloading machine for product processing applied in the field of reflow oven technology. Background Technology

[0002] A vacuum reflow oven is used to perform high-quality soldering on products in a vacuum environment. During the chip manufacturing process, when it needs to be soldered to a PCB circuit board, a vacuum reflow oven is required to ensure soldering quality. The vacuum reflow oven performs high-quality soldering on products in a vacuum environment. Under vacuum conditions, the products and solder are protected from oxidation, and the oxides on the surface of the products and solder react with each other, thereby improving the surface quality of the solder and reducing the void rate of the solder.

[0003] The reflow oven is the last critical step in surface mount technology. Reflow ovens involve manual loading and unloading of parts onto a reflow tray. The workpiece is placed in the tray, and then the tray is placed into the reflow oven. This process is labor-intensive. Therefore, most manufacturers currently use automatic loading and unloading equipment to replace manual loading and unloading. However, existing automatic loading and unloading equipment is not interchangeable. Using both machines together requires a large floor space, and each machine needs to be operated independently. The workload of these automated machines is not significantly reduced compared to manual loading and unloading, thus affecting the loading and unloading efficiency of the reflow oven. Summary of the Invention

[0004] In view of the above-mentioned prior art, the technical problem to be solved by the present invention is that the existing automatic feeding equipment and automatic unloading equipment are not universal, the two types of equipment occupy a large area, the amount of equipment operation is heavy, and the product processing efficiency is affected.

[0005] To solve the above problems, the present invention provides an integrated loading and unloading machine for product processing, including a loading and unloading channel mechanism fixed to the top of the machine body, a material box moving mechanism fixedly connected to the loading end of the loading and unloading channel mechanism, and a product feeding mechanism fixedly connected to the front end of the material box moving mechanism.

[0006] The material box movement mechanism includes an electric track, with a box gripper fixedly connected to the moving end of the electric track. The box gripper holds the material box, and material trays are stacked inside the material box. The product feeding mechanism includes a pushing track, which is parallel and corresponding to the box gripper. An ejection cylinder is fixedly connected to the end of the box gripper away from the pushing track, and an insertion cylinder is fixedly connected to the top of the pushing track. The output direction of the ejection cylinder is opposite to the output direction of the insertion cylinder. An extension track is hinged to the end of the pushing track adjacent to the electric track. The top surface of the extension track is horizontally aligned with the top surface of the pushing track, and the front end of the extension track extends into the material box. The bottom of the material box is hollow. A claw is fixedly connected to the bottom of the box gripper, and the claw is arranged in a U-shape corresponding to the extension track.

[0007] In the aforementioned integrated loading and unloading machine for product processing, a loading and unloading channel mechanism is used to transport the loading trays into the hopper. The hopper gripper grabs and adjusts the lifting and lowering of the hopper. Through push-out and push-in cylinders, the unprocessed trays in the hopper are pushed onto the push-material track, and the processed trays are pushed back into the hopper from the push-material track. The loading and unloading process is fully automatic, and the loading and unloading structure is simple. In addition, with the extension track to lengthen the push-material track, the trays in the hopper are lifted, effectively improving the stability of loading and unloading, thereby effectively improving the loading efficiency and facilitating the management of the loading and unloading equipment.

[0008] As a further improvement of this application, the loading and unloading channel mechanism includes a loading channel and a unloading channel, and the loading channel and the unloading channel are arranged in parallel. The output end of the loading channel and the input end of the unloading channel are both corresponding to the box gripper. The loading channel and the unloading channel are both slidably connected to the material box. The material box containing the unprocessed material tray is put into the loading channel, and the material box containing the processed material tray is sent out from the unloading channel.

[0009] As a further improvement of this application, a lifting push block is movably connected to the output end of the push cylinder. Both the lifting push block and the output end of the push cylinder are in contact with the material tray. The push cylinder indirectly pushes the material tray through the lifting push block, effectively avoiding the influence of the setting height of the push cylinder on the loading and unloading movement of the material tray.

[0010] As a further improvement of this application, a material tray groove is provided at the bottom of the lifting push block. The material tray groove engages with the edge of the material tray. By engaging the edge of the material tray with the material tray groove on the lifting push block, the lifting push block can simultaneously push and pull the material tray, simplifying the material tray pushing structure.

[0011] As another improvement of this application, the inner wall of the material box is provided with a placement groove and a guide groove, and the placement groove and the guide groove are arranged perpendicularly to each other. The guide groove is connected to the bottom of the material box. The placement groove in the material box facilitates the orderly placement of the material tray and the orderly ejection of the material tray.

[0012] As a further improvement to this application, a guide rod is fixedly connected to the front end of the extension track. Both ends of the guide rod are slidably connected to the guide groove. The guide rod moves up and down in the guide groove to realize the corresponding guidance of the extension track and the placement groove.

[0013] As a further improvement to this application, there are multiple placement slots, and the multiple placement slots are arranged in parallel at equal intervals. Both ends of the material tray are slidably connected to the placement slots. The placement slots facilitate the orderly stacking of material trays in the material box, thereby improving the loading and unloading efficiency of the material trays.

[0014] As another improvement of this application, a tightening port is fixedly connected to the connection between the guide groove and the placement groove. Positioning ends are fixedly connected to both ends of the guide rod. The positioning ends correspond to the tightening ports. The upper and lower ends of the tightening ports are both flared. The positioning ends pass through the tightening ports and contact the material tray. When the positioning ends slide in the guide groove, they enter the tightening ports and contact the material tray, thereby aligning the height of the extension track with the placement groove, which facilitates the extension track to guide the material tray for loading and unloading.

[0015] As a further improvement to this application, the positioning end is circular, and the diameter of the positioning end is larger than the width of the tightening opening. A pressure sensor is fixedly connected inside the positioning end. The positioning end is made of elastic rubber material. When the positioning end enters the tightening opening, it is squeezed and deformed due to the narrowing of the tightening opening, thereby slowing down the movement speed of the positioning end and effectively avoiding excessive pressure on the material tray by the positioning end. Combined with the compression detection of the pressure sensor, it facilitates the automatic braking of the box gripper and the automatic management of the loading and unloading integrated machine.

[0016] In summary, this solution uses a loading and unloading channel mechanism to transport the loading bins containing the pallets. The bins are then gripped by a grabber, and push-out and push-in cylinders are used to push unprocessed pallets onto the push-rail and processed pallets back into the bin. This simplifies loading and unloading operations for workers, and the simple structure occupies a small area. Furthermore, the extension track lengthens the push-rail, effectively supporting the pallets within the bin and improving loading and unloading stability, thereby increasing loading efficiency and facilitating the management of the loading and unloading equipment.

[0029] The two embodiments of this application will be described in detail below with reference to the accompanying drawings.

[0030] First implementation method:

[0031] Figure 1-3 The diagram shows an integrated loading and unloading machine for product processing, comprising a loading and unloading channel mechanism fixed to the top of the machine body 1. A material box moving mechanism is fixedly connected to the loading end of the loading and unloading channel mechanism, and a product feeding mechanism is fixedly connected to the front end of the material box moving mechanism. The material box moving mechanism includes an electric track 2, and a box gripper 201 is fixedly connected to the moving end of the electric track 2. The box gripper 201 grips a material box 202, and a material tray 203 is stacked inside the material box 202. The product feeding mechanism includes a pushing track 3, which is parallel and corresponding to the box gripper 201. A push-out cylinder is fixedly connected to the end of the box gripper 201 away from the pushing track 3. 301, The top of the pusher track 3 is fixedly connected to the pusher cylinder 302. The output direction of the pusher cylinder 301 is opposite to the output direction of the pusher cylinder 302. The loading and unloading channel mechanism includes the loading channel 4 and the unloading channel 401, and the loading channel 4 and the unloading channel 401 are arranged in parallel. The output end of the loading channel 4 and the input end of the unloading channel 401 are both corresponding to the box gripper 201. The loading channel 4 and the unloading channel 401 are both slidably connected to the material box 202. The material box 202 containing the unprocessed material tray 203 is put into the loading channel 4, and the material box 202 containing the processed material tray 203 is sent out from the unloading channel 401.

[0032] During the loading operation of the reflow oven, the operator places the unprocessed products into a specially designed tray 203, then stacks the tray 203 into the material box 202. The material box 202 is then placed into the loading channel 4. The electric track 2 drives the box gripper 201 to move towards the material box 202. The box gripper 201 grabs the material box 202 and lowers it. During the descent, the push cylinder 301 pushes the tray 203 onto the pusher track 3 in sequence, and then into the reflow oven through the pusher track 3. When the unloading operation is performed later, the tray 203 that has entered the pusher track 3 is pushed back into the material box 202 by the cylinder 302. Finally, the material box 202 descends into the unloading channel 401 and is sent out of the integrated machine through the unloading channel 401. The equipment has a simple structure, occupies a small area, and the loading and unloading operation is simple, effectively reducing the workload and improving the loading and unloading efficiency.

[0033] Figure 1 and Figure 4-5 As shown, the output end of the push cylinder 302 is movably connected to the lifting push block 303. The output ends of both the lifting push block 303 and the push cylinder 301 are in contact with the material tray 203. The push cylinder 302 indirectly pushes the material tray 203 through the lifting push block 303, effectively avoiding the setting height of the push cylinder 302 from affecting the up and down movement of the material tray 203. The bottom of the lifting push block 303 is provided with a material tray groove 304, which engages with the edge of the material tray 203. By engaging the edge of the material tray 203 through the material tray groove 304 on the lifting push block 303, the lifting push block 303 can simultaneously push and pull the material tray 203, simplifying the pushing structure of the material tray 203.

[0034] When the tray 203 containing the processed product is sent out of the reflow oven by the pusher track 3, the lifting pusher block 303 on the output end of the pusher cylinder 302 descends, and the tray groove 304 at the bottom of the lifting pusher block 303 locks the edge of the tray 203. The pusher cylinder 302 extends to push the tray 203 back into the material box 202. Conversely, the pusher cylinder 302 retracts to pull the tray 203 onto the pusher track 3. There is no need to use the push-out cylinder 301, which further simplifies the loading and unloading pushing structure.

[0035] Figure 5-6As shown, an extension rail 5 is hinged to one end of the pusher rail 3 adjacent to the electric rail 2. The top surface of the extension rail 5 is horizontally aligned with the top surface of the pusher rail 3, and the front end of the extension rail 5 extends into the material box 202. By extending the pusher rail 3 through the extension rail 5, the material tray 203 in the material box 202 is lifted, which effectively improves the stability of loading and unloading the material tray 203. The bottom of the material box 202 is hollow. The bottom of the box gripper 201 is fixedly connected to a claw 204, and the claw 204 is U-shaped corresponding to the extension rail 5. The hollow bottom of the material box 202, together with the U-shaped claw 204, makes it easy for the extension rail 5 to flip into the bottom of the material box 202, which facilitates the flipping and setting of the extension rail 5.

[0036] When the material tray 203 is being pushed up and down, the extension track 5 flips upward, and the bottom of the hollow material box 202 allows the extension track 5 to extend from the bottom, extending the pushing track 3 and directly supporting the material tray 203, effectively improving the stability of the material tray 203 being pushed up and down. The U-shaped claw 204 opens towards the extension track 5, effectively avoiding obstructing the upward flipping of the extension track 5.

[0037] Second implementation method:

[0038] Compared to the first embodiment, this embodiment adds a guide groove 6 and a guide rod 501. The specific additions are as follows, while the remaining structures are the same as in the first embodiment.

[0039] Figure 7-9 As shown, the inner wall of the material box 202 is provided with a placement groove 205 and a guide groove 6. The placement groove 205 and the guide groove 6 are arranged perpendicularly and intersecting each other. The front end of the extension rail 5 is fixedly connected to a guide rod 501. Both ends of the guide rod 501 are slidably connected to the guide groove 6. The placement groove 205 in the material box 202 facilitates the orderly placement of the material tray 203. The guide rod 501 moves up and down in the guide groove 6 to realize the corresponding guidance of the extension rail 5 and the placement groove 205. There are multiple placement grooves 205, and the multiple placement grooves 205 are arranged parallel to each other at equal intervals. Both ends of the material tray 203 are slidably connected to the placement groove 205. The placement groove 205 facilitates the orderly stacking of the material tray 203 in the material box 202, thereby improving the loading and unloading efficiency of the material tray 203.

[0040] Compared to the first embodiment, in this embodiment, after the extension track 5 flips to the bottom of the material box 202, the material box 202 moves downward and the guide rod 501 enters the guide groove 6, which effectively improves the stability of the extension track 5 moving in the material box 202. The material tray 203 slides in the placement groove 205, which effectively improves the sliding efficiency of the material tray 203 and facilitates the material tray 203 entering and leaving the material box 202.

[0041] Figure 7-10As shown, the bottom end of the guide groove 6 is connected to the outside of the bottom end of the material box 202. A tightening port 601 is fixedly connected to the connection part of the guide groove 6 and the placement groove 205. Both ends of the guide rod 501 are fixedly connected to positioning ends 502, which correspond to the tightening ports 601. The top of the positioning ends 502 contacts the material tray 203. When the positioning ends 502 slide in the guide groove 6, they enter the tightening ports 601 and contact the material tray 203, thereby aligning the height of the extension track 5 with the placement groove 205. This facilitates the extension track 5 in guiding the material tray 203 for loading and unloading. The upper and lower ends of the tightening ports 601 are both funnel-shaped. The positioning end 502 is circular, and its diameter is larger than the width of the tightening opening 601. A pressure sensor 503 is fixedly connected inside the positioning end 502. The positioning end 502 is made of elastic rubber material. When the positioning end 502 enters the tightening opening 601, it is squeezed and deformed due to the narrowing width of the tightening opening 601, thereby slowing down the movement speed of the positioning end 502 and effectively preventing the positioning end 502 from applying excessive pressure to the material tray 203. With the extrusion detection of the pressure sensor 503, it is convenient for the automatic braking of the box gripper 201 and the automatic management of the loading and unloading machine.

[0042] Compared to the first embodiment, in this embodiment, when the positioning end 502 slides in the guide groove 6, the positioning end 502 enters the tightening opening 601. Due to the narrowing of the width of the tightening opening 601, the positioning end 502 is squeezed and deformed. The deformation capability of the positioning end 502 is used to achieve braking and buffering of the positioning end 502. At the same time, the pressure sensor 503 collects the pressure to stop the material box 202, which makes it easier for the top of the positioning end 502 to contact the material tray 203. At the same time, it effectively avoids the positioning end 502 from applying excessive pressure to the material tray 203, and achieves alignment between the height of the extension track 5 and the placement groove 205.

[0043] In light of current practical needs, the above-described embodiments adopted in this application are not limited to these. Any changes made within the scope of knowledge possessed by those skilled in the art without departing from the concept of this application still fall within the protection scope of this invention.
