Description

Technical Field

[0001] The invention relates to the field of die bonding and chip placement equipment, and in particular to a track-type transport and positioning structure for flexible sheet products. Background Art

[0002] In the chip bonding industry, there are many ways to transport rigid substrates, which are also easy to achieve. For example, the transfer between the upper and lower processes can be achieved by clamping with a robot. However, for flexible thin semi-finished products, due to their easy deformation, the traditional robot clamping method cannot be used for transportation. Therefore, a method of transporting sheet products through an adsorption mechanism has emerged. However, the method of transporting 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 flat, but the flexible product will have a certain deformation, resulting in the adsorption surface not necessarily being flat, which can easily lead to adsorption failure and surface damage to the product;

[0004] 2) The adsorption process includes the processes of adsorption, lifting, swinging arms, and lowering. This requires that each step needs to be precisely debugged to ensure accurate positioning of the product after transfer. The debugging is difficult, time-consuming, and labor-intensive, and the production cost is correspondingly high;

[0005] 3) The adsorption mechanism requires a large number of precision parts to cooperate with each other. After a long period of operation, the precision parts are prone to wear and tear, resulting in inaccurate product positioning during the transfer process. Re-positioning and calibration are required, which has high maintenance costs. Frequent maintenance schedules also affect online production efficiency. Summary of the invention

[0040] See also Figure 1-8 The present invention provides a track-type transfer and positioning structure for flexible sheet products, including a track group arranged in parallel on a production line frame, the track group including a product track 1 and a handling track 2, the product track 1 is double-tracked and used to transport the flexible sheet products to be processed, and the handling track 2 is used to install a handling hand for transferring the products. The production line is divided into a loading station, a first positioning station, a second positioning station and a discharging station in sequence according to the length direction of the track group.

[0041] The first handling hand 21 corresponding to the loading station, the second handling hand 22 corresponding to the first positioning station, the third handling hand 23 corresponding to the second positioning station, and the fourth handling hand 24 corresponding to the discharging station are arranged in sequence on the handling hand track 2, and the first handling hand 21, the second handling hand 22, the third handling hand 23 and the fourth handling hand 24 are arranged on the same side; the first handling hand 21 reciprocates and transfers the product from the discharging station to the first positioning station for the first processing (such as dust removal or glue dispensing on the product), the second handling hand 22 reciprocates and transfers the product from the first positioning station to the second positioning station for the second processing (such as patching on the product), the third handling hand 23 reciprocates and transfers the product from the second positioning station to the discharging station, and the fourth handling hand 24 reciprocates and transfers the product from the discharging station to the next production process.

[0042] The product track 1 comprises a support rail 11 and an upper cover 12 covering the support rail 11. The support rail 11 and the upper cover 12 form a transfer chute 13 and a joint gap 14 after being matched. The transfer chute 13 and the joint gap 14 both extend along the length direction of the track set. The product track 1 is a double-track arrangement. The two transfer chutes 13 are relatively located on the inner sides of the two support rails 11. The flexible sheet products to be processed are supported in the two transfer chutes 13. During the operation of the production line, the products are always in the transfer chute 13 and transferred along the length direction of the support rail 11.

[0043] The function of the joint gap 14 is as follows: since the product to be processed is a flexible sheet product, and the two ends of the product are supported in 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 of the middle part of the product will bend downward and deform to a certain extent during the transfer process, which will cause the end of the product in the transfer chute 13 to be warped to a certain extent. In the design of the previous product track 1, the upper cover 12 did not deviate from the joint gap 14 between the support rails 11, which caused the warped parts at both ends of the product to be easily stuck in the tight fitting gap, resulting in unsmooth product transfer; while in the technical solution of the present application, there is a joint gap 14 with a certain width, and the joint gap 14 and the transfer chute 13 are not located on the same plane, so even if the thickness of the sheet product is very thin, it will not be stuck in the joint gap 14, and can only be located in the transfer chute 13, while reducing the processing accuracy and assembly accuracy requirements between the support rails 11 and the upper cover 12, solving the problem of easy jamming of thin sheet products.

[0044] The first positioning station is provided with a first processing table 31 , a first leveling mechanism 32 and a first positioning mechanism 33 ; 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 on the support rail 11 and corresponds to the first leveling mechanism 32 .

[0045] The first jacking mechanism 32 includes a first jacking motor, a first cam 322, a first lifting arm 323 and a first jacking bracket; the output shaft of the first jacking 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 jacking bracket, and the first jacking bracket is located directly below the product. Since the cam has the characteristic of different radii, when the first cam 322 rotates, it drives the first lifting arm 323 to rise and fall, thereby driving the first jacking bracket to rise and fall, and the initial state of the first jacking bracket is a low position, which can avoid interference with the product or the first processing table 31.

[0046] 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 platen 332, the first positioning platen 332 is located above the product, and the first positioning platen 332 and the first top flat bracket are located at the upper and lower sides of the product.

[0047] The workflow of the first positioning station is:

[0048] The first handling hand 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 a flexible sheet, the overhead position in the middle of the product will have a certain downward bending deformation, and the first processing table 31 can process the product only after the product is flattened; at this time, driven by the first flattening motor, the first flattening bracket rises from a low position and flattens the product from the bottom, and then the first positioning motor 331 drives the first positioning pressure plate 332 to descend and press the product. Under the joint action of the first flattening bracket and the first positioning pressure plate 332, the product is flatly fixed in the transfer chute 13, and then the first processing table 31 performs the first processing on the product (such as dust removal, gluing, etc.); after the first processing is completed, the first handling hand 21, the first flattening mechanism 32 and the first positioning mechanism 33 are reset, and thereafter the product that has undergone the first processing will be transferred to the second positioning station by the second handling hand 22.

[0049] The second positioning station is provided with a second processing table 41 , a second leveling mechanism 42 and a second positioning mechanism 43 ; the second processing table 41 and the second leveling mechanism 42 are arranged below the transfer chute 13 , and the second positioning mechanism 43 is arranged on the support rail 11 and corresponds to the second leveling mechanism 42 .

[0050] The second top leveling mechanism 42 includes a front-end top leveling component, a rear-end top leveling component, a second top leveling beam and a second top leveling bracket. The second top leveling beam is located below the product and its two ends are respectively connected to the front-end top leveling component and the rear-end top leveling component. The second top leveling bracket is fixedly mounted on the second top leveling beam, and the initial state of the second top leveling bracket is a low position.

[0051] The front end leveling assembly includes a front end leveling motor, a front end cam 421 and a front end lifting arm; the output shaft of the front end leveling 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 second leveling beam arranged horizontally;

[0052] The rear end leveling assembly includes a rear end leveling motor 422, a rear end cam and a rear end lifting arm that are synchronously operated with the front end leveling motor; the output shaft of the rear end leveling motor 422 is connected to and drives the rear end cam to rotate, the rear end cam is connected to the rear end lifting arm, and the vertically arranged rear end lifting arm is connected to the rear end of the second horizontally arranged leveling beam;

[0053] 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.

[0054] 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.

[0055] The workflow of the second positioning station is:

[0056] 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.

[0057] 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.

[0058] 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.

[0059] The top surface of the occlusal track plate 203 is provided with a trapezoidal protrusion.

[0060] The upper clamping component 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, and 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.

[0061] The lower clamping component 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, and 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.

[0062] The working principle of the first handling component is:

[0063] The bite motor 201 drives the driving plate 202, and the driving plate 202 drives the bite track plate 203 to reciprocate forward and backward. Since the upper clamp bearing 2043 contacts an inclined surface of the trapezoidal protrusion of the bite track plate 203, and the lower clamp bearing 2053 contacts another inclined surface of the trapezoidal protrusion of the bite track plate 203, under the action of the trapezoidal protrusion of the bite track plate 203, the upper clamp bearing 2043 and the lower clamp bearing 2053 respectively drive the upper clamp bending piece 2042 and the lower clamp bending piece 2052 to synchronously perform relative up and down reciprocating motions, thereby forming a bite opening between the upper clamp bending piece 2042 and the lower clamp bending piece 2052. When the bite opening is closed, the flexible sheet product to be processed is clamped, and the first type of conveying shaft is driven by the conveying motor to run on the conveying hand track 2, so that the product can be transported; when the bite opening is opened, the flexible sheet product to be processed is released, and the conveying motor drives the first type of conveying shaft to reset on the conveying hand track 2. The first handling hand 21 , the second handling hand 22 and the third handling hand 23 respectively use engageable first handling components to transfer the flexible sheet products to be processed.

[0064] The fourth transport arm 24 includes a second type transport shaft and left and right driving motors for driving the second type transport shaft to run on the transport arm track 2, and a second transport assembly is arranged on the second type transport shaft.

The hook electric cylinder 242 is connected to a hook 2422 via a hook arm 2421 , and the push rod electric cylinder 243 is connected to a push rod 2432 via a push rod arm 2431 .

[0066] The working principle of the fourth transporter 24 is:

[0067] After the third transporter 23 transports the product to the unloading station, the fourth transporter 24 takes over the product transport work. After the left and right drive motors drive the second type of transport axis to reach the product position, the hook electric cylinder 242 drives the hook 2422 to lower from a high position to a working position. Driven by the left and right drive motors, the hook 2422 hooks the product to the direction of the next process for a transport. After the transport is completed, the hook electric cylinder 242 and the hook 2422 are reset; then, the push rod electric cylinder 243 drives the push rod 2432 to lower from a high position to a working position. Driven by the left and right drive motors, the push rod 2432 pushes the product to the direction of the next process for a second transport, and finally pushes the product into the next process. Finally, the push rod electric cylinder 243 and the push rod 2432 are reset to complete the product transport process on the product track 1.

[0068] Compared with the prior art, the track-type transfer and positioning structure of a flexible sheet product in this case is implemented by setting four handling hands corresponding to four production stations. The first three handling hands transfer the products by means of upper and lower bite clamping, and the fourth handling hand sends the product to the next process by means of first hooking and then pushing. During the entire product transfer process, the product always remains in the product chute on the track, and a leveling mechanism and a positioning mechanism are provided at the first positioning station and the second positioning station to fix the product, thereby ensuring smooth product transfer, accurate positioning and high production efficiency.

It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the present invention, which all belong to the protection scope of the present invention.
