Abstract
Description
Technical Field
[0001] The utility model relates to the field of die bonding and chip mounting equipment, in particular to a processing track structure for flexible sheet products. Background Art
[0002] In the chip die bonding industry, there are many ways to transfer rigid substrates, and it is also very easy to achieve. For example, the transfer between upper and lower processes can be achieved by clamping with a manipulator. However, for flexible thin sheet semi-finished products, due to easy deformation, the traditional manipulator clamping method cannot be used for transfer. Therefore, a method of transferring sheet products through an adsorption mechanism has emerged. However, the method of transferring products through an adsorption mechanism also has the following defects:
[0003] 1) The adsorption head of the adsorption mechanism usually requires the adsorption surface to be a flat surface, while the flexible product will have a certain deformation, resulting in the adsorption surface not necessarily being flat, which easily leads to adsorption failure and surface damage to the product;
[0004] 2) The adsorption process includes the action processes of adsorption, lifting, swing arm, and lowering. This requires that each step needs to be precisely adjusted to ensure accurate positioning of the transferred product. The debugging is difficult, time-consuming and laborious, and the production cost is relatively high accordingly;
[0005] 3) The adsorption mechanism requires the cooperation of many precision parts. After a long operation time, the precision parts are easily worn, resulting in inaccurate product positioning during the transfer process. It is necessary to reposition and calibrate, and the maintenance cost is high. Frequent maintenance schedules also affect the online production efficiency. Content of the Utility Model

[0043] Please refer to Figures 1-9 , the present utility model provides a processing track structure for flexible sheet products, which includes a track group arranged in parallel on the production line rack. The track group includes a product track 1 and a handling robot track 2. Both the product track 1 and the handling robot track 2 are arranged in a double-track manner, and the handling robot track 2 is located on both sides of the product track 1. The product track 1 is used to transport the flexible sheet products to be processed, and the handling robot track 2 is used to install the handling robots for transporting the products. The production line is sequentially divided into a loading station, a first positioning station, a second positioning station, and an unloading station along the length direction of the track group.
[0044] On the handling robot track 2, a first handling robot 21 corresponding to the loading station, a second handling robot 22 corresponding to the first positioning station, a third handling robot 23 corresponding to the second positioning station, and a fourth handling robot 24 corresponding to the unloading station are sequentially arranged at intervals. The first handling robot 21 and the fourth handling robot 24 are located on the front side of the production line, and the second handling robot 22 and the third handling robot 23 are located on the rear side of the production line. The first handling robot 21 runs reciprocally and transports the product from the unloading station to the first positioning station for the first processing (such as dust removal or dispensing on the product), the second handling robot 22 runs reciprocally and transports the product from the first positioning station to the second positioning station for the second processing (such as chip mounting on the product), the third handling robot 23 runs reciprocally and transports the product from the second positioning station to the unloading station, and the fourth handling robot 24 runs reciprocally and transports the product from the unloading station to the next production process.
[0045] The product track 1 includes a supporting track 11 and an upper cover 12 covering the supporting track 11. After the supporting track 11 and the upper cover 12 are combined, a transfer chute 13 and a joint gap 14 are formed. Both the transfer chute 13 and the joint gap 14 extend along the length direction of the track group. The product track 1 is arranged in a double-track manner, and the two transfer chutes 13 are relatively located inside the two supporting tracks 11. The flexible sheet products to be processed are supported in the two transfer chutes 13, and the products are always in the transfer chutes 13 and are transported along the length direction of the supporting track 11 during the operation of the production line.
[0046] The function of the combination gap 14: Since the product to be processed is a flexible sheet product, and the brackets at both ends of the product are in the two transfer chutes 13, while the middle part of the product is in an overhead state. Under the action of the product's own gravity, the overhead position in the middle of the product will have a certain downward bending deformation during the transfer process, resulting in a certain degree of upward warping of the end of the product in the transfer chute 13. In the design of the previous product track 1, the upper cover 12 did not offset out of the combination gap 14 between the support rails 11, resulting in the warped parts at both ends of the product being easily stuck in the tight fitting gap, thus causing the product transfer to be unsmooth. In the technical solution of the present application, there is a combination gap 14 with a certain width, and the combination gap 14 and the transfer chute 13 are not in the same plane. Therefore, even if the thickness of the sheet product is very thin, it will not be stuck in the combination gap 14 and can only be located in the transfer chute 13. At the same time, the processing accuracy and assembly accuracy requirements between the support rail 11 and the upper cover 12 are reduced, and the problem that the thin sheet product is prone to jamming is solved.
[0047] A first processing table 31, a first leveling mechanism 32 and a first positioning mechanism 33 are provided at the first positioning station; the first processing table 31 and the first leveling mechanism 32 are arranged below the transfer chute 13, and the first positioning mechanism 33 is arranged outside the support rail 11 and corresponds to the first leveling mechanism 32.
[0048] The first leveling mechanism 32 includes a first leveling motor, a first cam 322, a first lifting arm 323 and a first leveling bracket; the output shaft of the first leveling motor is connected to and drives the first cam 322 to rotate, the first cam 322 is connected to the first lifting arm 323, the vertically arranged first lifting arm 323 is connected to the horizontally arranged first leveling bracket, and the first leveling bracket is located directly below the product. Due to the characteristic that the cam has different radii, when the first cam 322 rotates, it drives the first lifting arm 323 to lift and lower, thereby driving the first leveling bracket to lift and lower. The initial state of the first leveling bracket is in the low position, which can avoid interference with the product or the first processing table 31.
[0049] The first positioning mechanism 33 includes a first positioning motor 331, the output shaft of the first positioning motor 331 is connected to a first positioning pressing plate 332, the first positioning pressing plate 332 is located above the product, and the first positioning pressing plate 332 and the first leveling bracket are located on the upper and lower sides of the product respectively.
[0050] The working process of the first positioning station is as follows:
[0051] The first transfer arm 21 transfers the flexible sheet product to be processed to the position corresponding to the first processing table 31. Since the product to be processed is flexible and sheet-shaped, there will be a certain downward bending deformation at the overhead position in the middle of the product. The product must be flattened before the first processing table 31 can process the product. At this time, driven by the first flattening motor, the first flattening bracket rises from the low position and flattens the product from the bottom. Then, the first positioning motor 331 drives the first positioning pressing plate 332 to descend and press the product. Under the combined action of the first flattening bracket and the first positioning pressing plate 332, the product is flatly fixed in the transfer chute 13. Then, the first processing table 31 performs the first processing on the product (such as dust removal, dispensing, etc.). After the first processing is completed, the first transfer arm 21, the first flattening mechanism 32, and the first positioning mechanism 33 are reset. Thereafter, the product that has undergone the first processing will be transferred to the second positioning station by the second transfer arm 22.
[0052] A second processing table 41, a second flattening mechanism 42, and a second positioning mechanism 43 are provided at the second positioning station; the second processing table 41 and the second flattening mechanism 42 are provided below the transfer chute 13, and the second positioning mechanism 43 is provided outside the track 11 and corresponds to the second flattening mechanism 42.
[0053] The second flattening mechanism 42 includes a front-end flattening assembly, a rear-end flattening assembly, a second flattening cross beam, and a second flattening bracket. The second flattening cross beam is located below the product and is respectively connected to the front-end flattening assembly and the rear-end flattening assembly at both ends. The second flattening bracket is fixedly installed on the second flattening cross beam, and the initial state of the second flattening bracket is the low position.
[0054] The front-end flattening assembly includes a front-end flattening motor, a front-end cam 421, and a front-end lifting arm; the output shaft of the front-end flattening motor is connected to and drives the front-end cam 421 to rotate. The front-end cam 421 is connected to the front-end lifting arm, and the vertically arranged front-end lifting arm is connected to the front end of the horizontally arranged second flattening cross beam.
[0055] The rear-end flattening assembly includes a rear-end flattening motor that operates synchronously with the front-end flattening motor, a rear-end cam 422, and a rear-end lifting arm; the output shaft of the rear-end flattening motor is connected to and drives the rear-end cam 422 to rotate. The rear-end cam 422 is connected to the rear-end lifting arm, and the vertically arranged rear-end lifting arm is connected to the rear end of the horizontally arranged second flattening cross beam.
[0056] Since the front-end leveling assembly and the rear-end leveling assembly operate synchronously, the front-end leveling assembly and the rear-end leveling assembly jointly drive the second leveling bracket on the second leveling beam, and the second leveling bracket rises and falls and level the product from the bottom. At the second positioning station, the front-end leveling assembly and the rear-end leveling assembly are separately arranged, and the front and rear ends are connected by the second leveling beam. Such an arrangement can effectively avoid the interference of related production components, making the equipment deployment of the second processing table 41 more free, and the space is also more free when the second processing table 41 is adjusted according to production needs later.
[0057] The second positioning mechanism 43 includes a second positioning motor 431, the output shaft of the second positioning motor 431 is connected to the second positioning beam, and the second positioning pressure plate 432 is installed on the second positioning beam. The second positioning pressure plate 432 is located above the product, and the second positioning pressure plate 432 and the second top flat bracket are located at the upper and lower sides of the product relative to each other.
[0058] The workflow of the second positioning station is:
[0059] The second handling hand 22 transfers the flexible sheet product to be processed to the position corresponding to the second processing table 41. Since the product to be processed is a flexible sheet, the overhead position in the middle of the product will have a certain downward bending deformation, and the second processing table 41 can process the product only after the product is flattened; under the joint action of the front-end flattening component and the rear-end flattening component, the second flattening bracket rises from a low position and flattens the product, and then the second positioning motor 431 drives the second positioning pressure plate 432 to descend and press the product. Under the joint action of the second flattening bracket and the second positioning pressure plate 432, the product is flatly fixed in the transfer chute 13, and then the second processing table 41 performs a second processing on the product (such as patching, etc.); after the second processing is completed, the second handling hand 22, the second flattening mechanism 42 and the second positioning mechanism 43 are reset, and thereafter the product that has undergone the second processing will be transferred to the unloading station by the third handling hand 23.
[0060] The first transport arm 21, the second transport arm 22 and the third transport arm 23 have the same structure and working principle, and all include a first type of transport shaft and a transport motor driving the first type of transport shaft to run on the transport arm track 2, and the first type of transport shaft is provided with a first transport component.
[0061] The first conveying component includes a base No. 200, an engagement motor 201, a drive plate 202, an engagement track plate 203, an upper clamping member and a lower clamping member; the base No. 100 and the drive plate 202 are horizontally arranged and slidably matched through a slide rail, the engagement track plate 203 is vertically arranged and fastened to the drive plate 202, the engagement motor 201 drives the drive plate 202 to slide on the base No. 200, the upper clamping member and the lower clamping member are relatively arranged on the upper and lower sides of the product, and the upper clamping member and the lower clamping member are respectively connected to the engagement track plate 203 through bearings.
[0062] The occlusal track plate 203 has a trapezoidal protrusion on its top surface.
[0063] The upper clamping member includes an upper clamping arm 2041, an upper clamping bending piece 2042, and an upper clamping bearing 2043; the upper clamping bending piece 2042 is fixedly installed at one end of the upper clamping arm 2041, the upper clamping bearing 2043 is rotatably installed at the other end of the upper clamping arm 2041, and the upper clamping bearing 2043 contacts an inclined surface of the trapezoidal protrusion of the occlusal track plate 203.
[0064] The lower clamping member includes a lower clamping arm 2051, a lower clamping bending piece 2052, and a lower clamping bearing 2053; the lower clamping bending piece 2052 is fixedly installed at one end of the lower clamping arm 2051, the lower clamping bearing 2053 is rotatably installed at the other end of the lower clamping arm 2051, and the lower clamping bearing 2053 contacts the other inclined surface of the trapezoidal protrusion of the occlusal track plate 203.
[0065] The working principle of the first handling assembly is as follows:
[0066] The occlusion motor 201 drives the drive plate 202, and the drive plate 202 drives the occlusal track plate 203 to move back and forth. Since the upper clamping bearing 2043 contacts an inclined surface of the trapezoidal protrusion of the occlusal track plate 203, and the lower clamping bearing 2053 contacts the other inclined surface of the trapezoidal protrusion of the occlusal track plate 203, under the action of the trapezoidal protrusion of the occlusal track plate 203, the upper clamping bearing 2043 and the lower clamping bearing 2053 drive the upper clamping bending piece 2042 and the lower clamping bending piece 2052 to synchronously perform relative up and down reciprocating movements, thereby forming a clamping opening between the upper clamping bending piece 2042 and the lower clamping bending piece 2052. When the clamping opening is closed, the flexible sheet product to be processed is clamped, and by driving the first type of handling shaft to run on the handling hand track 2 by the handling motor, the product can be transported; when the clamping opening is opened, the flexible sheet product to be processed is released, and the handling motor drives the first type of handling shaft to reset on the handling hand track 2. The first handling hand 21, the second handling hand 22, and the third handling hand 23 respectively use the biteable first handling assembly to transport the flexible sheet product to be processed.
[0067] The fourth handling hand 24 includes a second type of handling shaft and a left and right drive motor 246 for driving the second type of handling shaft to run, and a second handling assembly is provided on the second type of handling shaft.
[0068] The second handling assembly includes a second base 241, a swing rod drive motor 242 is provided on the second base, the output shaft of the swing rod drive motor 242 is connected to the middle of a swing rod 243, hook claw members and push rod members are respectively installed at both ends of the swing rod 243, the hook claw member includes a hook claw 244, and the push rod member includes a push rod 245.
[0069] The working principle of the fourth transfer arm 24 is as follows:
[0070]
[0070] After the third transfer arm 23 transfers the product to the discharging station, the fourth transfer arm 24 takes over the transfer work of the product. After the left and right drive motors 246 drive the second type of transfer shaft to reach the product position, the swing rod drive motor 242 starts. The output shaft of the motor rotates reciprocally according to the actual production requirements. The output shaft of the swing rod drive motor 242 drives the swing rod 243 to perform a seesaw-like movement. The swing rod 243 first drives the claw member to lower from the high position to the working position. Driven by the left and right drive motors 246, the claw 244 hooks the product and transfers it in the direction of the next process once. After the first transfer is completed, the swing rod 243 and the claw member reset; then, the swing rod 243 drives the push rod member to lower from the high position to the working position. Driven by the left and right drive motors 246, the push rod 245 pushes the product to perform a second transfer in the direction of the next process and finally pushes the product into the next process. Finally, the swing rod 243 and the push rod member reset, completing the transfer process of the product on the product track 1.
[0071] Compared with the prior art, in a flexible sheet product processing track structure of this case, by setting four transfer arms corresponding to four production stations, the first three transfer arms all transfer the product in the way of upper and lower clamping, and the fourth transfer arm sends the product into the next process by the way of first hooking and then pushing. During the whole product transfer process, the product always remains in the product chute on the track. Moreover, a flattening mechanism and a positioning mechanism are both set at the first positioning station and the second positioning station to fix the product, so as to ensure smooth product transfer, accurate positioning and high production efficiency.
[0072] The above embodiments only represent several implementation manners of the present invention. The description is relatively specific and detailed, but it should not be construed as a limitation on the scope of the utility model patent. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present invention, several deformations and improvements can still be made, and these all belong to the protection scope of the present invention.
