Description

Technical Field

[0001] This utility model relates to the field of automated processing equipment, specifically to an automatic feeding device and a mounting machine having the automatic feeding device. Background Technology

[0002] In existing technologies, such as chip manufacturing, components are usually mounted on a mounting machine. These components are typically stored in a tray. After the tray is transported to the loading position, a robotic arm takes them out one by one from the tray for mounting.

[0003] In existing placement machines, the material feeding module for the tray is usually located inside the machine. This occupies internal space, resulting in a larger overall machine size. Furthermore, the machine needs to be stopped for replacement when the tray is full or empty, impacting production cycle time and efficiency. In some placement machines, the material feeding module is mounted externally, without any protection, leading to frequent accidental contact by operators and posing a safety risk. Additionally, the disassembly and assembly of the feeding module is inconvenient, affecting overall production efficiency. Utility Model Content

[0046] The preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings, so that the advantages and features of the present invention can be more easily understood by those skilled in the art. It should be noted that the description of these embodiments is for the purpose of aiding understanding the present invention, but does not constitute a limitation thereof. Furthermore, the technical features involved in the various embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0047] See Figures 1 to 14 An automatic feeding device is shown, configured to supply material 6 to other processing equipment. The automatic feeding device includes:

[0048] The base 11 has a first side 1A and a second side 1B, which are two different sides on the base 1 along a first direction;

[0049] The storage mechanism 2 is located on the first side 1A of the base 1. The storage mechanism 2 includes a bracket 21 that can be raised and lowered in the vertical direction, and a lifting drive assembly for driving the bracket 21 to rise and fall in the vertical direction. The material tray 5 storing the material 6 is stacked on the bracket 21 in the vertical direction. Under the drive of the lifting drive assembly, the material tray 5 can be raised and lowered, so that the material tray 5 reaches the required height position.

[0050] The feeding mechanism 4 is located on the second side 1B of the machine base 1. The feeding mechanism 4 has a feeding platform 41, and the feeding platform 41 is provided with a loading part 411 for carrying the material 6.

[0051] The material handling mechanism 3 includes a material handling arm 34, which has a material handling head 341 for adsorbing material 6. The material handling arm 34 is rotatably arranged about a vertically extending rotation axis (not shown in the figure) so that the material handling head 341 can move between the material tray 5 and the loading part 411, thereby picking up material 6 from the material tray 5 and transferring it to the loading part 411, from which the feeding table 41 supplies material 6 to other processing equipment.

[0052] When the feeding device is used to supply material 6 to other processing equipment, the tray 5 containing material 6 is stacked vertically on the bracket 21 and located on the first side 1A of the machine base 1. The feeding device can be moved as a whole to one side of the other processing equipment, so that the second side 1B of the machine base 1 is engaged with the other processing equipment. The material taking mechanism 3 takes material 6 from the tray 5 supported by the bracket 21 on the storage mechanism 2 and transfers it to the loading part 411 of the feeding table 41. The feeding table 41 then supplies material 6 to the other processing equipment. In this way, the tray 5 containing material 6 can be placed on the feeding device at a location different from the aforementioned processing equipment, and the feeding device can be moved as a whole to engage with the processing equipment, thereby supplying material 6 to the processing equipment. The feeding device is located outside the processing equipment, without occupying the internal space of the processing equipment, and will not make the overall size of the processing equipment too large. At the same time, multiple feeding devices can be configured to connect to the processing equipment, allowing the processing equipment to continuously feed materials or feed different materials without stopping the machine, thus avoiding affecting the production cycle and efficiency. The feeding device can be independently equipped with a casing, so that each mechanism is protected by the casing, avoiding accidental contact and safety risks.

[0053] Specifically, see Figures 3 to 7 As shown, the base 1 includes a machine platform 11 and a storage seat 12 provided on the first side 1A. The storage seat 12 is provided with a receiving cavity 13. The bracket 21 is slidably disposed in the receiving cavity 13 in the vertical direction. When the material tray 5 is stacked on the bracket 21 in the vertical direction, it is also received in the receiving cavity 13. The storage seat 12 can provide good protection for the material tray 5 and the material 6 inside it, avoiding the risk of the material tray 5 falling.

[0054] The lifting drive assembly includes a lead screw 24 extending vertically, a first motor 27 driving the lead screw 24 to rotate around its own axis, a nut 23 threadedly engaged with the lead screw 24, and a top rod 22 fixedly connected to the nut 23 at one end. The lifting drive assembly is located outside the receiving cavity 13, and the other end of the top rod 22 extends into the receiving cavity 13 and is fixedly connected to the bottom of the bracket 21. Thus, when the first motor 27 drives the lead screw 24 to rotate, the nut 23 moves up and down along the lead screw 24, and drives the top rod 22 to move up and down synchronously, thereby driving the bracket 21 to move up and down in the receiving cavity 13, and correspondingly causing the tray 5 supported by the bracket 21 to rise and fall synchronously.

[0055] The material storage mechanism 2 also includes multiple push cylinders 25, which are disposed on the material storage seat 12 and located outside the receiving cavity 13. Each push cylinder 25 has a push member 251 that can extend into the receiving cavity 13. Here, there are four push members 251 arranged opposite each other and in pairs. The bottom outer side of the material tray 5 is provided with four positioning grooves 52. When the four push members 251 extend into the receiving cavity 13, they can be inserted into the four positioning grooves 52 accordingly.

[0056] After all the material 6 in the uppermost tray 5 has been removed, the push cylinder 25 remains in a retracted state, and the lifting drive assembly drives the bracket 21 upward, causing all the trays 5 to rise. When the uppermost tray 5 just reaches above the push member 251, the push member 251 extends into the receiving cavity 13 and is inserted into the four positioning slots 52 accordingly, so that the uppermost tray 5 is supported on the push member 251. Then the lifting drive assembly drives the bracket 21 downward, causing the other trays 5 to descend until the uppermost tray 5 reaches the preset height position, and then the picking arm 34 of the picking mechanism 3 picks up the material from it.

[0057] Once the tray 5 is emptied, all trays 5 are lifted upwards until they touch the bottom of the tray 5 supported by the pusher 251, at which point the pusher 251 retracts. The bracket 21 continues to rise to the height of one tray 5. Subsequently, the pusher 251 extends and engages with the corresponding tray 5, allowing all empty trays 5 to be stacked and supported on the pusher 251. The bracket 21 then descends, causing the uppermost tray 5 to reach a preset height position and engage with the picking arm 34 of the picking mechanism 3. In this way, when all trays 5 are emptied, they are stacked vertically on the pusher 251, making it easy for the operator to move them away as a whole and replace full trays 5, making loading very convenient.

[0058] The storage mechanism 2 also includes multiple side-push cylinders 26. The height of the side-push cylinders 26 corresponds to the preset height position mentioned above. When the material tray 5 containing the material 6 reaches the preset height, and before cooperating with the picking arm 34 to pick up the material, the side-push cylinders 26 extend and push against the side of the material tray 5, so that the material tray 5 is aligned, so as to achieve accurate positioning and picking up of the material in cooperation with the picking arm 34.

[0059] Referring to the accompanying drawings, the feeding platform 41 of the feeding mechanism 4 is movably arranged along a first direction, allowing the feeding platform 41 to move between a receiving position and a feeding position. When the feeding platform 41 is in the receiving position, the picking arm 34 of the picking mechanism 3 places the material 6 onto the loading portion 411 of the feeding platform 41. When the feeding platform 41 is in the feeding position, it supplies the material 6 to the processing equipment. The feeding mechanism 4 also includes a slide 42 slidably arranged on the machine base 1 along the first direction. The feeding platform 41 is mounted on the slide 42. When the slide 42 slides along the first direction toward the second side 1B, it allows the feeding platform 41 to move from the receiving position to the feeding position to supply the material 6 to the processing equipment. In this embodiment, when the feeding platform 41 is in the receiving position, the distance between the loading part 411 and the rotating shaft is the same as the distance between the picking head 341 and the rotating shaft. After the picking head 341 picks up the material 6 from the material tray 5, the picking arm 34 rotates around the rotating shaft at a certain angle, and the picking head 341 is located directly above the loading part 411, so that the material 6 can be directly transferred to the loading part. When the feeding platform 41 is in the feeding position, the distance between the loading part 411 and the rotating shaft increases, and the loading part 411 extends relative to the second side 1B in the direction away from the first side 1A. In this feeding position, the feeding platform 41 extends out of the housing of the feeding device and can extend into the housing of the processing equipment.

[0060] Referring to the accompanying drawings, the feeding platform 41 is rotatably mounted on the slide 42 about a vertically extending swing axis (not shown in the figures). The feeding mechanism 4 also includes an adjustment assembly for driving the feeding platform 41 to rotate about the swing axis to adjust the angle of the feeding platform 41, so that the position of the loading part 411 on the feeding platform 41 can be adjusted, thereby adjusting the position of the material 6 on it for precise feeding to the processing equipment. Specifically, the adjustment assembly includes a first synchronous pulley 44, a second synchronous pulley, a synchronous belt 45 tensioned between the first synchronous pulley 44 and the second synchronous pulley, and a second motor 43 for driving the first synchronous pulley 44 to rotate. The feeding platform 41 is fixed on the second synchronous pulley. In this way, the feeding platform 41 can be rotated about the swing axis to adjust the angle, so that the adsorption and picking device on the processing equipment can directly position and pick up the material from the feeding platform 41 and perform subsequent processing.

[0061] Referring to the accompanying drawings, the material tray 5 has multiple material slots 51 arranged in an array along a first direction and a second direction perpendicular to the first direction. That is, each material tray 5 simultaneously carries several materials 6, which are distributed in an array on the material tray 5. See here. Figure 1 , Figure 2 As shown, the first direction is the X direction, the second direction is the Y direction, and the up and down direction corresponds to the Z direction. The material tray 5 is rectangular and extends along the Y direction in the length direction and along the X direction in the width direction on the material storage mechanism 2.

[0062] The material handling mechanism 3 includes a crossbeam 31, a movable seat 32, and a mounting seat 33. The crossbeam 31 is movable on the base 1 in a first direction; the movable seat 32 is movable on the crossbeam 31 in a second direction; the mounting seat 33 is vertically mounted on the movable seat 32; one end of the material handling arm 34 is rotatably mounted on the mounting seat 33 around a rotation axis; a third motor 35 is provided on the top of the mounting seat 33 to drive the material handling arm 34 to rotate, which allows the material handling arm 34 to move in the XYZ directions. At the same time, the material handling arm 34 can also rotate so that the material handling head 341 alternately switches between above the material tray 5 and above the feeding table 41.

[0063] The material handling mechanism 3 also includes a synchronous belt assembly mounted on a movable seat. The synchronous belt assembly includes a synchronous belt 36 arranged rotatably in the vertical direction, two synchronous pulleys 37 spaced apart in the vertical direction, and a fourth motor 38 that drives one of the synchronous pulleys 37 to rotate. The synchronous belt 36 is tensioned between the two synchronous pulleys 37. The mounting seat 33 is fixed on one side of the synchronous belt 36 extending in the vertical direction. By rotating the fourth motor 38 in both directions, the synchronous pulleys 37 are driven to rotate by the same angle, which allows the material handling arm 34 to alternately rise and fall between two height positions, thereby realizing the picking up and releasing of material 6 and its transmission.

[0064] According to another aspect of the present invention (not shown), the present invention also provides a mounting machine, which includes a machine body having a workspace for mounting products to be processed within the workspace; the mounting machine also includes the above-mentioned automatic feeding device, which is detachably connected to the machine body and, when connected, the feeding table 41 can extend into the workspace to supply material 6 to the machine body.

[0065] In summary, when the automatic feeding device of this embodiment is used for automatic feeding processing in a mounting machine, it can be directly transported to one side of the machine body using a forklift or other transport vehicle, so that its second side 1B docks with the machine body. Figure 3 , Figure 7 As shown, a limiting wheel 14 is also provided on the second side 1B of the base 1 to abut against the machine body and form a limit, so as to avoid damage to components such as the feeding mechanism 4 when the second side 1B is engaged with the machine body. The material tray 5 storing the material 6 can be placed into the storage mechanism 2 before or after engaging with the machine body.

[0066] After the automatic feeding device is connected to the machine body, the bracket 21 in the storage mechanism 2 is raised and lowered, causing the material tray 5 to be picked up to a preset height position. Then, under the action of the side-push cylinder 26, it is guided and aligned. (See below) Figures 11 to 14As shown, in the material handling mechanism 3, the material handling head 341 of the material handling arm 34 cooperates with the material tray 5 to pick up the material 6. The material handling arm 34 rotates and can selectively translate along the X-axis or Y-axis, so that the material handling head 341 reaches above the feeding table 41 and places the material 6 into the loading part 411. Then, the slide 42 slides away from the first side 1A, and the feeding table 41 extends towards the working space of the machine body under the sliding drive of the slide 42 to supply the machine body with the material 6. Then, the slide 42 slides back towards the first side 1A, and the feeding table 41 returns to the receiving position to receive the material 6 picked up again by the material handling arm 34. This process is repeated to achieve continuous feeding.
