Description

Technical Field

[0001] The present invention belongs to the technical field of mechanical transfer, and relates to a product positioning and transfer device, in particular to a product positioning and transfer device, a processing assembly line and an operation method. Background Art

[0002] With the continuous development of economy and technology, the application of 3C products is becoming more and more extensive. Nowadays, 3C electronic products have become an indispensable part of all walks of life;

[0003] 3C electronic products include computers, mobile phones, TVs, digital audio and video products and their related industrial products. For example, the outer shell of the structural parts in a mobile phone belongs to a thin-shell product. During the manufacturing process, the outer shell needs to be placed in an injection molding device for injection molding. Due to the number and structure of the shell gate and other situations, it is easy to cause product deformation and distortion during the process of manual placement and removal. At the same time, in the prior art, the product needs to be taken out from the tray and transferred to the device. There are situations such as gaps or different spacings during the transfer and assembly processes, and the product needs to be repositioned and the distance changed through a positioning platform. Usually, the positioning method of positioning pins is adopted, but during the process

[0004] It is impossible to avoid situations such as zero contact between positions. If the gap between the PIN needles is too large, the product will fall off, and if it is too small

[0005] it will cause damage to the PIN needles and cannot meet the requirements of precise feeding. For example, the Chinese patent discloses a lifting and unlocking mechanism, application number CN202121934264.6, a tape PIN automatic alignment feeding mechanism, which includes a cutting device for accessing the tape and cutting the PIN needles, a jaw device that can rotate and extend and clamp the PIN needles, and an alignment and pushing device for positioning the PIN needles; the alignment and pushing device includes a fixed frame, an alignment plate that is arranged on the fixed frame and can move up and down, a connecting plate that is fixedly arranged above the fixed frame, and a docking plate that is arranged at the bottom of the connecting plate and can move horizontally. The upper and lower ends of the alignment plate are respectively provided with horizontally opened positioning holes. The alignment plate is arranged close to and in contact with the docking plate. The bottom of the connecting plate is provided with a clamping groove for limiting the top of the alignment plate. The back of the docking plate is provided with a pushing block corresponding to the positioning holes. The jaw device transfers and positions the PIN needles into the positioning holes.

[0006] The present disclosure provides a tape PIN automatic alignment feeding mechanism. By changing the traditional PIN needle positioning method and setting an alignment and pushing device, the PIN needles after the tape is cut are transferred by the jaw device into the positioning holes in the alignment plate. The alignment plate moves up and down in cooperation with the docking plate, and the docking plate horizontally feeds the PIN needles in the positioning holes to the required working position, ensuring the efficient, automated and precise feeding of the PIN needles.

[0007] Although the above - mentioned solution has the above - mentioned advantages, the structure of the above - mentioned solution does not solve the product positioning problem and cannot avoid positioning collisions. At the same time, it does not realize moving the product into the injection mold to achieve continuous switching between material taking and material placing. Summary of the Invention

The opening - closing driver is arranged at both ends of the clamping station, and the opening - closing driver drives a pair of anti - detachment claws to perform opening and closing actions.

[0014] In the above - mentioned product positioning and transfer device, the anti - detachment claw has a connecting cross - block. One end of the connecting cross - block is integrally convex with a hook claw at the bottom side, and an embedding notch is recessed on the outer wall surface of the connecting cross - block. The driving block of the opening - closing driver is embedded in the embedding notch to form a fixed connection.

[0015] In the above - mentioned product positioning and transfer device, a semi - circular clamping notch is recessed on the bent hook body of the hook claw, and the two clamping notches in a pair of anti - detachment claws are closed to form a complete - circle clamping opening.

[0016] In the above-mentioned product positioning and transfer device, a clearance space is reserved between the bent hook body of the hook claw and the connecting cross block. The two clearance spaces in a pair of anti-detachment claws are combined to form a complete through opening. The top surface of the bent hook body is a downward inclined surface from the inside to the outside, and the conical cavity bottom of the through opening is formed by combining a pair of the downward inclined surfaces.

[0017] In the above-mentioned product positioning and transfer device, the lifting and limiting mechanism includes a substrate. A lifter is fixedly arranged below the substrate. The lifting shaft of the lifter penetrates through the substrate to form a free telescopic movement. The top end of the lifting shaft exposed from the substrate is fixedly connected with a carrier plate. At least one of the lower positioning structures is erected on the substrate. A through hole is correspondingly opened on the carrier plate. The lower positioning structure penetrates into the through hole from bottom to top to form a sliding connection.

[0018] In the above-mentioned product positioning and transfer device, a plurality of guide posts are also erected on the substrate. A plurality of guide holes are correspondingly opened on the carrier plate. The plurality of guide posts are in one-to-one correspondence with the plurality of guide holes to form a vertical sliding connection.

[0019] In the above-mentioned product positioning and transfer device, the adsorption station includes a lower pressure device. The lower pressure device extends downward to protrude a lower pressure rod. The bottom end of the lower pressure rod is fixedly connected with a pressing plate. The bottom side of the pressing plate is connected with an adsorption plate through a plurality of buffer springs. At least one vacuum suction port is arranged on the bottom surface of the adsorption plate.

[0020] In the above-mentioned product positioning and transfer device, at least one of the upper positioning structures is erected on the plate. At least one through hole is correspondingly opened on the adsorption plate. The upper positioning structure penetrates into the through hole from top to bottom to form a sliding connection.

[0021] In the above-mentioned product positioning and transfer device, a transfer frame is provided on the transfer device. The clamping station and the adsorption station are installed on the transfer frame. At least four positioning columns are penetrated through the transfer frame. At least four positioning cylinders matching the positioning columns one by one are arranged on the positioning platform.

[0022] A processing production line includes the product positioning and transfer device according to any one of the above.

[0023] An operation method of the processing production line includes the following steps:

[0024] 1), The product is fixed on the carrier plate at the loading station of the positioning platform through the lower positioning structure. The transfer device moves to directly above the positioning platform and gradually presses down, so that the positioning columns correspondingly penetrate into the positioning cylinders to form a preliminary positioning. At this time, the adsorption station of the transfer device and the loading station of the positioning platform are vertically aligned.

[0025] 2) The lifter drives the carrier plate to move upward and abut against the adsorption plate. The adsorption station and the material loading station are gradually pressed together, and the buffer spring between the adsorption plate and the pressure plate is gradually compressed. As a result, the upper positioning structure extends downward from the adsorption plate, passes through the product, and extends into the carrier plate. Under the resistance of the lifting limit of the carrier plate, the upper positioning structure and the lower positioning structure face each other up and down, and there is a collision prevention gap between them.

[0026] 3) The adsorption plate sucks the product through the vacuum suction port. The elevator drives the adsorption station to lift and separate the product from the material loading station. Synchronously, the lifter drives the carrier plate to move downward and reset. Then the transfer device transfers the product to the injection mold of the injection molding machine for injection molding operation.

[0027] 4) After injection molding is completed, the injection mold ejects the injection molded product. The transfer device moves above the injection mold. The elevator drives the clamping station to descend. The anti-detachment claws are driven by the opening and closing driver to clamp both ends of the injection molded gate of the injection molded part. The connecting hook frame is pulled back by the telescopic device to hook the injection molded gates on both sides of the injection molded part respectively, thereby taking out the completed injection molded product.

[0028] In the operation method of the above processing pipeline, in step 4), after the transfer device takes out the injection molded product in the injection mold through the clamping station, it then puts the un-injected product into the injection mold through the adsorption station, realizing the continuous switching of mold taking and material placing.

[0029] Compared with the prior art, the operation method of the product positioning and transfer equipment and the processing pipeline of the present product has the following beneficial effects:

[0030] The product positioning problem is solved through this equipment, avoiding situations such as positioning collision and deviation between positions. At the same time, the functions of product adsorption, clamping, and transfer are realized. This not only ensures the positioning accuracy of the product, but also avoids the labor costs and labor errors generated by manual feeding and receiving. It saves time and improves production efficiency. Moreover, this equipment has a simple structure and flexible functions, and has a good market prospect. Description of the Drawings

Detailed implementation manners

[0038] The following are specific embodiments of the present invention and, in combination with the accompanying drawings, further describe the technical solutions of the present invention, but the present invention is not limited to these embodiments.

[0039] Embodiment 1

[0040] As Figures 1 to 5 shown, a product positioning and transfer device of the present invention includes a transfer device and a positioning platform that are in upper - lower positioning cooperation. The transfer device is alternately arranged with clamping station a and adsorption station b, and the clamping station a and the adsorption station b are respectively driven and connected by a lifter; at least one loading station c is provided on the positioning platform; the product is clamped and adsorbed for transfer through the clamping station a and the adsorption station b, and the material is positioned by placing it on the loading station c.

[0041] An upper positioning structure b1 is provided on the adsorption station b, and a lower positioning structure c1 is provided on the loading station c. The upper positioning structure b1 and the lower positioning structure c1 are in one - to - one corresponding cooperation for positioning; a lifting limit mechanism c2 is provided on the loading station c, and the lifting limit mechanism c2 is overhead the adsorption station b, so as to leave a collision - proof gap between the upper positioning structure b1 and the lower positioning structure c1.

[0042] The clamping station a includes an adsorption structure in the middle and a hook - clamping structure on the periphery. The hook - clamping structure includes hook frame assemblies a1 that slide parallel on both sides, and anti - detachment assemblies a2 that are oppositely arranged at both ends.

[0043] To hook out the product for easy clamping and transfer, as Figures 1 to 3As shown, the hook frame assembly a1 includes two connecting hook frames a11 and at least one telescopic device a12. A slider a111 is fixedly arranged inside the connecting hook frame a11, and sliding guide rails a3 are fixedly arranged on both sides of the clamping station a. The telescopic device a12 drives the connecting hook frame a11 to be slidably connected to the sliding guide rail a3. In this embodiment, there are at least two connecting hook frames a11 to facilitate hooking out the glue ports on both sides of the product, avoiding situations such as offset when hooking out from one side. At the same time, the hooks on the connecting hook frame a11 can be in an inverted L shape, with one end being the hook mouth and the other end being sealed. The sealed end is integrated with the connecting hook frame a11, and the hook mouth openings face the same direction outward for easy hooking of the material. In the embodiment, the telescopic device a12 can be a driving electric cylinder, a cylinder, a hydraulic cylinder, an electric push rod, etc., all of which can achieve the driving effect. Through the telescopic device a12, the hooks on the connecting hook frame a11 reciprocate and slide on both sides of the clamping station a.

[0044] The anti - detachment assembly a2 includes at least a pair of anti - detachment claws a21 and an opening - closing driver a22. The opening - closing driver a22 is arranged at both ends of the clamping station a, and the opening - closing driver a22 drives a pair of anti - detachment claws a21 to perform opening and closing actions. When the connecting hook frame a11 hooks out the product, the glue ports at both ends drive a pair of anti - detachment claws a21 through the driver a22 to clamp and close the glue ports at both ends, so as to prevent the product from shaking, shifting during the transfer process, resulting in product detachment, inaccurate positioning, etc.

[0045] As Figure 3 and Figure 6 shown, the anti - detachment claw a21 has a connecting cross - block. One end of the bottom side of the connecting cross - block is integrally convex with a hook claw a211, and an embedding notch a212 is recessed on the outer wall surface of the connecting cross - block. The driving block a221 of the opening - closing driver a22 is embedded in the embedding notch a212 to form a fixed connection. Through the two driving blocks a221 of the opening - closing driver a22, a pair of oppositely arranged hook claws a211 are driven to open or close, so as to clamp the gate between the two hook claws a211.

[0046] A semi - circular clamping notch a2111 is recessed on the bent hook body of the hook claw a211. The two clamping notches a2111 in a pair of anti - detachment claws a21 are closed to form a complete circular clamping opening. The formed complete circular clamping opening fits with the cylindrical outer wall of the gate, thereby improving the tightness and enhancing the stability and firmness of the clamping.

[0047] As Figure 6 shown, a clearance space is left between the bent hook body of the hook claw a211 and the connecting cross - block. The two clearance spaces in a pair of anti - detachment claws a21 are combined to form a complete through - opening a213. The top surface of the bent hook body is a downward inclined surface from the inside to the outside, and the two downward inclined surfaces are combined to form the conical cavity bottom of the through - opening a213. Through the through - opening a213, a receiving space for the top end of the gate is formed, so that more parts of the gate enter the clamping cavity of the anti - detachment claws, enhancing the stability and firmness of the clamping.

[0048] To achieve product positioning while avoiding positioning collisions, such as Figure 1 and Figure 5 As shown, the lifting limit mechanism c2 includes a substrate c21. A lifter c22 is fixedly installed below the substrate c21. The lifting shaft c222 of the lifter c22 penetrates through the substrate c21 to form a freely telescopic movement. The top end of the lifting shaft c222 exposed from the substrate c21 is fixedly connected to a carrier plate c23. At least one lower positioning structure c1 is erected on the substrate c21. A through hole c231 is correspondingly opened on the carrier plate c23. The lower positioning structure c1 penetrates into the through hole c231 from bottom to top to form a sliding connection. By performing a lifting action with the lifter c22, the top carrier plate c23 is driven to rise, causing the lower positioning structure c1 to relatively descend in the through hole c231 to avoid positioning collisions and other situations.

[0049] To prevent the product from shifting and other situations, in this embodiment, a number of guide posts c211 are also erected on the substrate c21. A number of guide holes c232 are correspondingly opened on the carrier plate c23. The number of guide posts c211 corresponds to the number of guide holes c232 one by one to form a vertical sliding connection. By abutting the guide holes c232 against the adsorption station b, a product guiding effect is formed.

[0050] To achieve a good adsorption effect on the product, such as Figure 1 , Figure 2 and Figure 4 As shown, the adsorption station b includes a lower pressure device b2. The lower pressure device b2 extends downward to protrude a lower pressure rod b21. The bottom end of the lower pressure rod b21 is fixedly connected to a pressure plate b3. The bottom side of the pressure plate b3 is connected to an adsorption plate b5 through a number of buffer springs b4. At least one vacuum suction port b51 is provided on the bottom surface of the adsorption plate b5. The adsorption plate b5 is elastically connected through the buffer springs b4. When the lower pressure rod b21 performs a downward pressing action, the buffer springs b4 between the connecting pressure plate b3 and the adsorption plate b5 are compressed, so that the adsorption plate b5 better fits the adsorbed surface of the product.

[0051] In this embodiment, to prevent the product from shifting and other situations during the adsorption process, at least one upper positioning structure b1 is erected on the pressure plate b3. At least one through hole b52 is correspondingly opened on the adsorption plate b5. The upper positioning structure b1 penetrates into the through hole b52 from top to bottom to form a sliding connection. When the lower pressure device b2 drives the lower pressure rod b21 to perform a downward pressing action, the upper positioning structure b1 extends out of the through hole b52. The upper positioning structure b1 erected on the pressure plate b3 and the lower positioning structure c1 erected on the substrate c21 face each other up and down. Through the lower pressure device b2 and the lifter c22, a collision prevention gap is left between the two.

[0052] To ensure the positioning effect of the product and avoid shifting and other situations, such as Figure 1 and Figure 2As shown in the figure, the transfer device is provided with a transfer rack d. The clamping station a and the adsorption station b are installed on the transfer rack d. At least four positioning columns d1 are penetrated through the transfer rack d, and at least four positioning cylinders e that are in one-to-one correspondence with the positioning columns d1 are arranged on the positioning platform. Through the cooperation of the positioning columns d1 and the positioning cylinders e, the positioning accuracy between the transfer device and the positioning platform is ensured.

[0053] Compared with the prior art, the positioning and transfer device of this product has the following beneficial effects:

[0054] The positioning and transfer device of this product solves the product positioning problem, avoids situations such as positioning collision and offset during positioning, and at the same time realizes the functions of product adsorption, clamping, and transfer. It not only ensures the positioning accuracy of the product, but also avoids the labor costs and labor errors generated by manual feeding and receiving materials, saves time and improves production efficiency. Moreover, this device has a simple structure and flexible functions, and has a good market prospect.

[0055] Embodiment 2

[0056] Based on Embodiment 1 as Figures 1 to 5 As shown in the figure, the processing pipeline includes the above-mentioned product positioning and transfer device, and also includes an injection molding machine. An injection mold is arranged in the injection molding machine, and the transfer device is connected between the positioning platform and the injection mold.

[0057] Embodiment 3

[0058] Based on Embodiments 1 and 2, this embodiment is as follows:

[0059] The operation method of the processing pipeline includes the following steps:

[0060] 1). The product is fixed on the carrier plate c23 at the loading station c of the positioning platform through the lower positioning structure c1. The transfer device moves to directly above the positioning platform and gradually presses down, so that the positioning columns d1 correspondingly penetrate into the positioning cylinders e to form a preliminary positioning. At this time, the adsorption station b of the transfer device and the loading station c of the positioning platform are vertically aligned.

[0061] 2). The lifter c22 drives the carrier plate c23 to move upward and abut against the adsorption plate b5. The adsorption station b and the loading station c are gradually pressed together, and the buffer spring b4 between the adsorption plate b5 and the pressure plate b3 is gradually compressed, so that the upper positioning structure b1 extends downward out of the adsorption plate b5 and then penetrates through the product and extends into the carrier plate c23. Under the resistance of the lifting limit of the carrier plate c23, the upper positioning structure b1 and the lower positioning structure c1 form a vertical confrontation and there is a collision prevention gap between the two.

[0062] 3) The adsorption plate b5 sucks the product through the vacuum suction port b51. The lifter drives the adsorption station b to lift up and pick and separate the product from the loading station c. The synchronous lifter c22 drives the carrier plate c23 to move down and reset. Then, the transfer device transfers the product into the injection mold of the injection molding machine for injection molding operation.

[0063] 4) After the injection molding is completed, the injection mold ejects the injection molded product. The transfer device moves above the injection mold. The lifter drives the clamping station a to descend. The anti - detachment claws a21 are driven by the opening and closing driver a22 to clamp both ends of the injection molded gate of the injection molded part. The connecting hook frame a11 is pulled back by the telescopic device a12 to hook the injection molded gates on both sides of the injection molded part correspondingly, thereby taking out the completed injection molded product.

[0064] After the transfer device takes out the completed injection molded product from the injection mold through the clamping station a, it then puts the un - injection - molded product into the injection mold through the adsorption station b, realizing a continuous switching mode of material taking and material placing.

[0065] Compared with the prior art, the operation method of this processing line has the following beneficial effects:

[0066] This processing line can put the un - injection - molded product into the injection mold to ensure continuous feeding of the product, improve production capacity and convenience, and realize a continuous switching mode of material taking and material placing, reduce the labor cost of loading and unloading materials, save time, and improve production efficiency.

The lifter drives the carrier plate to move upward and abut against the adsorption plate. The adsorption station and the loading station are gradually pressed together, and the buffer spring between the adsorption plate and the pressure plate is gradually compressed, so that the upper positioning structure extends downward out of the adsorption plate and then penetrates through the product and extends into the carrier plate. Under the blocking action of the lifting limit of the carrier plate, the upper positioning structure and the lower positioning structure form a vertical confrontation and a collision prevention gap is left between the two. 3). The adsorption plate sucks the product through the vacuum suction port. The lifter drives the adsorption station to lift and separate the product from the loading station. At the same time, the lifter drives the carrier plate to move downward and reset. Then the transfer device transfers the product to the injection molding die in the injection molding machine for injection molding operation. 4). After the injection molding is completed, the injection molding product is ejected from the injection molding die. The transfer device moves above the injection molding die. The lifter drives the clamping station to descend. The anti-detachment claws are driven by the opening and closing driver to clamp the injection molding gates at both ends of the injection molded part. The connecting hook frame is pulled back by the telescopic device to correspondingly hook the injection molding gates on both sides of the injection molded part, so as to take out the injection molded product that has completed injection molding.

12. The operating method of the processing pipeline according to claim 11, wherein In step 4), after the transfer device takes out the injection molded product in the injection molding die through the clamping station, the non-injection molded product is put into the injection molding die through the adsorption station, so as to realize the continuous switching mode of taking and placing materials.
