Description

Technical Field

[0001] This utility model relates to the field of electronic and semiconductor device processing, and specifically to a rotary feeding conveyor. Background Technology

[0002] Currently, in the production process of electronic and semiconductor devices, automated processing is typically achieved through the cooperation of processing equipment and feeding equipment to efficiently complete the product manufacturing. The feeding equipment transports the product to a designated location, where the processing head of the processing equipment aligns with its position before proceeding with the appropriate processing. To improve processing efficiency, the product is usually positioned on the conveyor table of the feeding equipment, avoiding the need for the processing head to adjust its position based on the actual location of the product before each processing cycle.

[0003] When a product is placed on a workbench, it typically needs to be positioned first so that the processing device can cooperate with it for processing. Currently, a positioning structure is usually set up on the workbench, and the two sides of the product are pushed by X-axis pushers that translate in the X direction and Y-axis pushers that translate in the Y direction, so that the product cooperates with the positioning structure on the workbench to achieve positioning. However, the above method requires X-axis and Y-axis drive mechanisms, such as linear motors or cylinders, which requires a large space in the X and Y directions, resulting in an excessively large lateral dimension of the processing equipment. Especially for small-sized products, the traditional positioning structure will seriously occupy the processing space of the equipment, affecting the overall production efficiency of a single machine. At the same time, the thrust exerted directly on the product by the cylinder or linear motor may cause product damage and affect the production qualification rate. Utility Model Content

[0044] 40. Products. Detailed Implementation

[0045] 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.

[0046] See Figures 1 to 10 The rotary feeding conveyor shown is used to automatically feed the product 40 in a rotary manner, so that the product 40 can be automatically conveyed to different processing stations for corresponding processing.

[0047] The rotary feeding conveyor includes a rotary disk 10, a plurality of clamping devices 20 arranged circumferentially on the rotary disk 10, and a drive device 30. The rotary disk 10 is rotatably arranged about a vertically extending rotation center line to convey the product 40 circumferentially. The clamping devices 20 are capable of clamping the product 40 and have a clamping state that clamps and fixes the product 40, and a non-clamping state that releases the product 40. The drive device 30 is used to cooperate with the clamping devices 20 so that the clamping devices 20 can switch between the clamping state and the non-clamping state.

[0048] Specifically, the clamping device 20 includes:

[0049] A fixed base 3 is fixedly mounted on the rotating disk 10. The fixed base 3 has a positioning groove 3A for positioning the product 40. The positioning groove 3A includes a horizontally extending bottom wall 33 and a first side wall 31 and a second side wall 32 extending vertically upwards from the bottom wall 33. One end of the first side wall 31 and the second side wall 32 are connected, and their extending directions are perpendicular to each other. When the product 40 is placed into the positioning groove 3A, the bottom wall 33 supports the product 40, and the first side wall 31 and the second side wall 32 position two adjacent sides of the product 40.

[0050] A first clamping seat 1 is rotatably disposed on a rotating disk 10 about a first axis X1. The first clamping seat 1 has a first clamping surface 11 facing the first sidewall 31.

[0051] The second clamping seat 2 is rotatably mounted on the rotating disk 10 about the second axis X2. The second clamping seat 2 has a second clamping surface 21 facing the second side wall 32. The second axis X2 is perpendicular to the first axis X1 and both extend in the horizontal direction.

[0052] A first elastic element (not shown in the figure) provides the force required for the first clamping seat 1 to rotate so that the first clamping surface 11 moves closer to the first side surface 31.

[0053] The second elastic element (not shown in the figure) provides the force required for the second clamping seat 2 to rotate so that the second clamping surface 21 moves closer to the second side surface 32.

[0054] When the clamping device 20 is in the clamping state, the first clamping surface 11, the second clamping surface 21 and the positioning groove 3A cooperate to form a clamping space for clamping the product 40. At least part of the upper part of the product 40 is exposed outside the clamping space to be processed by other processing devices. When the clamping device 20 is in the non-clamping state, both the first clamping surface 11 and the second clamping surface 21 are offset from the positioning groove 3A, so that the product 40 can be easily placed into the positioning groove 3A or removed from the positioning groove 3A.

[0055] In this embodiment, when no external force is applied, the clamping device 20 can remain in the clamping state under the action of the first elastic member and the second elastic member; the driving device 30 can be disposed in conjunction with the first clamping seat 1 and the second clamping seat 2 so that the clamping device 20 can be switched from the clamping state to the non-clamping state.

[0056] Thus, multiple processing stations are arranged along the circumference of the rotary disk 10. The number of clamping devices 20 on the rotary disk 10 is equal to or greater than the number of processing stations, and at least one processing station is equipped with a drive device 30. During the rotation of the rotary disk 10, when the clamping device 20 reaches the station equipped with the drive device 30, the drive device 30 engages with the first clamping seat 1 and the second clamping seat 2, causing the clamping device 20 to switch to a non-clamping state. Subsequently, the unloading device can remove the processed product 40 from the clamping device 20, or place the next product 40 to be processed onto the clamping device 20. When the drive device 30 disengages from the first clamping seat 1 and the second clamping seat 2, the clamping device 20 returns to the clamping state, clamping the product 40 and performing corresponding processing as the rotary disk 10 rotates, thereby improving the efficiency of transmission and processing.

[0057] In this transmission device, the first clamping seat 1 and the second clamping seat 2 are both rotatably mounted on the rotary disk 10. By simply driving the first clamping seat 1 and the second clamping seat 2 to rotate, they can cooperate with the fixed seat 3 to fix and clamp the product 40. Its structure is compact and occupies little space. It does not require horizontally extending X-axis and Y-axis drive devices to drive the corresponding clamping seats to translate and achieve clamping and positioning of the product 40, thus avoiding occupying a large table area on the rotary disk 10, thereby avoiding the overall size of the transmission device being too large and affecting the improvement of production efficiency.

[0058] See Figures 4 to 10As shown, in this embodiment, when the clamping device 20 is in the clamping state, the first clamping surface 11 and the first sidewall 31 are parallel to each other, and the distance between them is consistent with the thickness of the product 40. The second clamping surface 21 and the second sidewall 32 are parallel to each other, and the distance between them is consistent with the length of the product 40. Thus, the product 40 is placed in the positioning groove 3A, supported on the bottom wall 33 along the height direction. Its two sides in the thickness direction abut against the first sidewall 31 and the first clamping surface 11, respectively, and its two sides in the length direction abut against the second sidewall 32 and the second clamping surface 21, respectively, so that the product 40 is completely positioned and clamped, thereby facilitating the processing of the part of the product 40 exposed in the clamping space.

[0059] In this embodiment, the first clamping base 1 includes a first clamping portion 12 with a first clamping surface 11. The first clamping portion 12 includes a lower clamping block 1b extending horizontally and a plurality of upper clamping blocks 1a extending vertically upward from the upper end of the lower clamping block 1b. The plurality of upper clamping blocks 1a are arranged at intervals along the same straight line. Two adjacent upper clamping blocks 1a and lower clamping blocks 1b cooperate to form an upward-opening U-shaped groove 1c. In the clamping state, at least a portion of the side of the product 40 is exposed from the U-shaped groove 1c to facilitate processing. In specific configuration, the positions of the plurality of upper clamping blocks 1a and lower clamping blocks 1b are mainly determined according to the position of the part of the product 40 to be processed. Here, the upper part of the fixing base 3 is also provided with a plurality of through holes 34, which communicate with the positioning groove 3A. In the clamping state, the side of the product 40 facing the first sidewall 31 is also exposed from the through holes 34, thereby enabling processing.

[0060] Referring to the accompanying drawings, in this embodiment, the first axis X1 and the second axis X2 are at the same height in the vertical direction, and both the first axis X1 and the second axis X2 are located below the fixed base 3. Here, the rotating disk 10 includes a disk body 101 and a plurality of mounting bases 102 fixed on the disk body 101. The number and position of the plurality of mounting bases 102 correspond one-to-one with the number and position of the plurality of clamping devices 20. On each clamping device 20, the fixed base 3 is fixedly mounted above the mounting base 102. The first clamping base 1 is rotatably connected to the mounting base 102 around the first rotating shaft 4, and the second clamping base 2 is rotatably connected to the mounting base 102 around the second rotating shaft 5. The axis lines of the first rotating shaft 4 and the second rotating shaft 5 respectively constitute the first axis X1 and the second axis X2.

[0061] The first clamping seat 1 includes a first clamping portion 12 and a first seat portion 13 connected at one end. The first clamping portion 12 extends vertically and a first clamping surface 11 is disposed on the first clamping portion 12. The first seat portion 13 extends horizontally, and a first axis X1 is disposed at the position where the first clamping portion 12 and the first seat portion 13 meet. Specifically, the first clamping portion 12 and the first seat portion 13 form an L-shaped structure, and a first rotating shaft 4 is disposed at the corner of the L-shaped structure. The first seat portion 13 is located below the fixed seat 3, and a first elastic element, specifically a spring, is disposed between the first seat portion 13 and the fixed seat 3. The bottom of the first seat portion 13 also has a downwardly extending first protrusion 14 for engaging with the driving device 30. The first protrusion 14 and the first rotating shaft 4 are spaced apart along the length of the first seat portion 13, so that the first clamping seat 1 as a whole can rotate around the first axis X1 when the first protrusion 14 is driven to move.

[0062] Similarly, the second clamping seat 2 includes a second clamping portion 22 and a second seat portion 23 connected at one end. The second clamping portion 22 extends vertically and a second clamping surface 21 is provided on the second clamping portion 22. The second seat portion 23 extends horizontally, and a second axis X2 is provided at the position where the second clamping portion 22 and the second seat portion 23 meet. Specifically, the second clamping portion 22 and the second seat portion 23 form an L-shaped structure, and the second rotating shaft 5 is provided at the corner of the L-shaped structure. The second seat portion 23 is located below the fixed seat 3, and a second elastic member is provided between the second seat portion 23 and the fixed seat 3. The second elastic member is specifically a spring. The bottom of the second seat portion 23 is also provided with a downwardly extending second protrusion 24 for engaging with the driving device 30. The second protrusion 24 and the second rotating shaft 5 are spaced apart along the length of the second seat portion 23, so that the second clamping seat 2 as a whole can rotate around the second axis X2 when the second protrusion 24 is driven to move.

[0063] The drive device 30 specifically includes a drive base 303, a first push block 304 and a second push block 305 fixed above the drive base 303, and a lifting drive component for driving the drive base 303 to rise and fall in the vertical direction. Here, the lifting drive component is a cylinder, which includes a cylinder seat 301 fixedly disposed and a telescopic rod 302 connected to the cylinder seat 301 in the vertical direction. The drive base 303 is fixed to the top of the telescopic rod 302. When the cylinder is working, it drives the drive base 303 to rise and fall, so that the first push block 304 and the second push block 305 rise and fall synchronously in the vertical direction.

[0064] The first pusher block 304 has a first top surface 304a at the top, and the second pusher block 305 has a second top surface 305a at the top. When the cylinder moves upward, the first protrusion 14 abuts against the first top surface 304a, and the second protrusion 24 abuts against the second top surface 305a. This allows the first pusher block 304 and the second pusher block 305 to push the first protrusion 14 and the second protrusion 24 to move during the upward movement of the drive seat 303, thereby causing the first clamping seat 1 and the second clamping seat 2 to rotate, thus realizing the transition of the clamping device 20 from the clamping state to the non-clamping state.

[0065] In this embodiment, the bottoms of both the first protrusion 14 and the second protrusion 24 are arc-shaped. During the upward lifting process, they can slide relative to each other on the tops of the first top surface 304a and the second top surface 305a, resulting in smoother sliding and preventing jamming. The first top surface 304a is an inclined surface extending upward towards the first axis X1, and the second top surface 305a is an inclined surface extending upward towards the second axis X2. Thus, during the upward movement of the first push block 304 and the second push block 305 driving the first protrusion 14 and the second protrusion 24 to rotate, it can create clearance between the first protrusion 14 and the second protrusion 24 in the height direction, allowing the first clamping seat 1 and the second clamping seat 2 to rotate smoothly.

[0066] Here, the rotating disk 10 is provided with a first through groove 103 and a second through groove (not shown in the figure) extending through in the vertical direction. The first protrusion 14 and the second protrusion 24 are correspondingly inserted into the first through groove 103 and the second through groove. The first push block 304 and the second push block 305 can be correspondingly inserted into the first through groove 103 and the second through groove in the vertical direction, so as to engage with the first protrusion 14 and the second protrusion 24 in the vertical direction.

[0067] In summary, this utility model's rotary feeding conveyor transports product 40. Product 40 can be loaded onto the clamping device 20, and during the clamping process, product 40 can be conveyed to different processing stations for corresponding processing as the rotary disk 10 rotates. After processing, the driving device 30 drives the clamping device 20 to switch to a non-clamping state to unload product 40, realizing automatic loading, unloading, and conveying of product 40. The clamping device 20 uses a rotating first clamping seat 1 and a second clamping seat 2 to cooperate with the fixed seat 3 to clamp product 40. Its structure is compact, greatly reducing the space occupied on the table, making the overall structure of the conveyor more compact and space-saving, while also significantly improving feeding efficiency. It is especially suitable for multi-process automatic processing of small semiconductor products.
