Detailed Implementation

[0017] 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, thereby providing a clearer and more explicit definition of the scope of protection of the present invention.

[0018] Please see Figure 2This invention provides an improved fully automatic insert embedding and molding device 100, suitable for the fully automatic embedding of inserts 3 with 32 openings at the ends in injection molding production, and the recovery of finished products after overmolding. It enables fully unmanned operation from insert 3 feeding, transfer, injection molding to finished product collection, effectively solving the problems of low efficiency, high labor costs, and significant safety hazards associated with traditional semi-automatic operations. It also overcomes the technical bottleneck of existing fully automatic devices being unable to adapt to the 32 openings at the ends of inserts 3. The overall structure is rationally designed, operates stably and efficiently, and is suitable for large-scale mass production needs.

[0019] Specifically, the improved fully automatic insert embedding and molding device 100 includes an insert conveying assembly 10 and an insert transfer assembly 20. The insert transfer assembly 20 is located on one side of the insert conveying assembly 10, and the two work together to complete the fully automated processing of the insert 3.

[0020] Please refer to Figure 3 The insert conveying assembly 10 is used to realize the automated conveying and loading / unloading of inserts 3. It includes a conveyor belt mechanism, an insert clamping mechanism 12, an insert clamping mechanism 13, an insert pallet conveying mechanism 18, and an insert pallet storage mechanism 19. Each part has a compact structure and smooth connection.

[0021] The conveyor belt mechanism (not shown in the figure) serves as the core carrier for conveying the insert 3, and includes a conveyor drive motor and two conveyor belts arranged side-by-side. For those skilled in the art, the conveyor belt mechanism is readily conceived and will not be described in detail. The tray 14 is positioned between conveyor belts one and two, and is driven by the conveyor drive motor to ensure smooth transport of the tray 14. The insert conveyor assembly 10 has a conveyor frame one 16 and a conveyor frame two 17 corresponding to the positions of conveyor belts one and two, arranged side-by-side and symmetrically, providing stable support for the entire conveyor belt mechanism and other auxiliary components.

[0022] An insert pallet conveying mechanism 18 is located upstream of the insert clamping mechanism 12 and is used to automatically feed the inserts 3 to be processed. It includes lifting and clamping cylinder modules 181 respectively installed on conveyor frame 16 and conveyor frame 17 in corresponding positions. The lifting and clamping cylinder module 181 consists of a first lifting cylinder 1811, a first clamping cylinder 1812, and a clamping plate 1813. The first lifting cylinder 1811 is vertically mounted on the frame, the first clamping cylinder 1812 is horizontally connected to the output end of the first lifting cylinder 1811, and the clamping plate 1813 is fixed to the output end of the first clamping cylinder 1812. During operation, the first lifting cylinder 1811 drives the first clamping cylinder 1812 and the clamping plate 1813 to lift to a specified height. The first clamping cylinder 1812 drives the clamping plate 1813 to clamp the tray 14. Then, through the lifting action of the first lifting cylinder 1811, the tray 14 is placed on the conveyor belt, realizing the automatic lowering of the tray 14.

[0023] The insert storage tray mechanism 19 is located downstream of the insert clamping mechanism 13 and is used to store the tray 14 containing the finished overmolded insert 3. It includes insert clamping cylinder modules 191 respectively located on conveyor frame one 16 and conveyor frame two 17 in corresponding positions. The insert clamping cylinder module 191 consists of a second lifting cylinder 1911 and a clamping plate two 1912. The second lifting cylinder 1911 is vertically installed, and the clamping plate two 1912 is fixed to the output end of the second lifting cylinder 1911. The end face of the clamping plate two 1912 is provided with an arc-shaped locking block (not shown in the figure). The second lifting cylinder 1911 drives the second clamping plate 1912, lifting the pallet. It only descends when a new pallet 14 containing finished products is delivered to the insert storage pallet mechanism 19. During descent, the lifted pallet is placed onto the new pallet below. The clamping plate 1912, along with the arc-shaped locking block, descends to below the edge of the lowest pallet, and then lifts all the pallets together. A spring is also provided between the clamping plate 1911 and the arc-shaped locking block for clamping and releasing the pallet 14. Specifically, the spring is located between the clamping plate and the arc-shaped locking block, causing the arc-shaped locking block to clamp; the clamping force is the spring's natural restoring force. Release is achieved by the arc-shaped locking block being subjected to force from the edge of the lowest new pallet during descent, causing the arc-shaped locking block to move outwards in an arc around a rotation point and then open; each arc-shaped locking block has one spring on each side.

[0024] The insert clamping mechanism 12 and the insert clamping mechanism 13 are symmetrically arranged on both sides of the conveyor belt mechanism. They have the same structure and are used to clamp and transfer the insert to be processed 3 and to clamp and store the finished insert 3 coated with rubber. Taking the insert clamping mechanism 12 as an example, it specifically includes a linear drive module 121, a slider rail module 122, a linear drive module 123, an insert moving unit 124, and a tray blocking unit 125.

[0025] Linear drive module 121 is installed on the outside of conveyor frame 16, and slider rail module 122 is installed on the outside of conveyor frame 17. Linear drive module 123 is positioned between linear drive module 121 and slider rail module 122, forming a stable lateral movement frame. Linear drive module 121 uses a servo motor and ball screw drive to ensure the accuracy of linear drive module 123's movement.

[0026] The insert moving unit 124 is connected to the linear drive module 2 123 and can move along the driving direction of the linear drive module 2 123. It includes a third lifting cylinder 1241 and a gripping fixture 1242. The third lifting cylinder 1241 is vertically connected to the moving end of the linear drive module 2 123, and the gripping fixture 1242 is fixed to the output end of the third lifting cylinder 1241. Figure 1 The insert 3 shown has structural features. The insert 3 is divided into an end 32 with an opening and a rod 31 connected to the end 32. The gripping jig 1242 is designed for this structure and has at least two pairs of contour blocks for gripping the insert 3. Each pair of contour blocks has a vacuum suction hole on its inner side. The insert 3 is stably gripped and transferred by the contour blocks fitting against the rod 31 of the insert 3 and the vacuum suction hole adsorbing the rod. During operation, linear drive module 121 and linear drive module 223 work together to move insert moving unit 124 above tray 14. Third lifting cylinder 1241 drives gripping fixture 1242 to descend. The contour block fits the rod 31 of insert 3, and the vacuum suction hole aligns with the rod 31 of insert 3, generating negative pressure adsorption. Then, third lifting cylinder 1241 rises, and linear drive module 121 and linear drive module 223 work together to drive insert moving unit 124 to accurately transfer insert 3 into placement slot 21331 of intermediate transfer fixture 2133.

[0027] The pallet blocking unit 125 is connected between conveyor frame 16 and conveyor frame 17 to achieve precise positioning of the pallet 14. It includes a connector 1251, a fourth lifting cylinder 1252, and a blocking plate 1253. The connector 1251 is fixed between the two frames, the fourth lifting cylinder 1252 is vertically mounted on the connector 1251, and the blocking plate 1253 is fixed to the output end of the fourth lifting cylinder 1252. When the pallet 14 is conveyed by the conveyor belt to the working position of the insert clamping mechanism 12 or the insert clamping mechanism 13, the fourth lifting cylinder 1252 drives the blocking plate 1253 to rise, preventing the pallet 14 from continuing to move and ensuring precise positioning. After the operation is completed, the fourth lifting cylinder 1252 drives the blocking plate 1253 to descend, releasing the pallet 14.

[0028] The insert transfer assembly 20 is located between the insert clamping mechanism 12 and the insert clamping mechanism 13, and is used to realize the transfer of the insert 3 between the conveying assembly and the injection mold. It includes the insert intermediate transfer mechanism 21 and the fixture transfer injection molding mechanism 22.

[0029] like Figure 4-6 As shown, the insert intermediate transfer mechanism 21 is used to transfer the insert to be processed 3 clamped by the insert clamping mechanism 12 to the transfer fixture 211, or to transfer the rubber-coated finished insert 3 in the transfer fixture 211 to the insert clamping mechanism 13. It includes a mounting plate 212, an insert receiving module 213, and a rotating clamping module 214.

[0030] Mounting plate 212 is a horizontally positioned rectangular plate structure that serves as the mounting carrier for each component of the insert intermediate transfer mechanism 21, ensuring the precise installation position of each component.

[0031] The insert receiving module 213 includes a linear drive module 2131, a placement plate 2132, and an intermediate transfer fixture 2133. The linear drive module 2131 is horizontally mounted on the mounting plate 212. The placement plate 2132 is connected to the moving end of the linear drive module 2131 and can move horizontally under the drive of the linear drive module 2131. The intermediate transfer fixture 2133 is fixed to the placement plate 2132 and has at least two placement slots 21331 for receiving inserts 3. The shape of the placement slots 21331 is adapted to the inserts 3 to ensure stable placement of the inserts 3. During operation, the linear drive module 2131 drives the placement plate 2132 and the intermediate transfer fixture 2133 to the discharge end of the insert clamping mechanism 12 to receive the inserts 3 to be processed transferred by the insert clamping mechanism 12, and then moves to the working position of the rotary clamping module 214.

[0032] The rotating clamping module 214 includes a rotating unit 2141, a moving unit 2142, a clamping unit 2143, and a transfer fixture placement unit 2144. The clamping unit 2143 is the core improved component of this invention for the design of the opening at the end 32 of the insert 3.

[0033] The rotating unit 2141 includes a rotating motor 21411 and a rotating component 21412. The rotating component 21412 includes a first rotating bracket 214121, a second rotating bracket 214122, and a rotating shaft 214123. The first rotating bracket 214121 and the second rotating bracket 214122 are arranged parallel to each other and spaced apart. The rotating shaft 214123 is installed between the first rotating bracket 214121 and the second rotating bracket 214122. It should be noted that bearings are provided at the points where the first rotating bracket 214121 and the second rotating bracket 214122 meet the rotating shaft 214123, allowing the rotating shaft 214123 to be connected via these bearings. The output end of the rotating motor 21411 is connected to one end of the rotating shaft 214123, driving the rotating shaft 214123 to rotate.

[0034] The moving unit 2142 is mounted on the rotating component 21412 and includes a first guide rod 21421, a second guide rod 21422, a first drive cylinder 21423, a second drive cylinder 21424, and a moving plate 21425. The first guide rod 21421 and the second guide rod 21422 are vertically connected to the rotating shaft 214123 and are parallel to each other. The first drive cylinder 21423 is located near the first guide rod 21421 and away from the second guide rod 21422, and the second drive cylinder 21424 is located near the second guide rod 21422 and away from the first guide rod 21421; both are horizontally positioned. The movable plate 21425 is sleeved on the first guide rod 21421 and the second guide rod 21422, and its two ends are respectively connected to the output ends of the first drive cylinder 21423 and the second drive cylinder 21424. Under the coordinated drive of the first drive cylinder 21423 and the second drive cylinder 21424, it can move smoothly along the length direction of the first guide rod 21421 and the second guide rod 21422 to ensure the lifting accuracy of the clamping unit 2143.

[0035] The gripping unit 2143 includes a plurality of gripping cylinders 21431 disposed on the movable plate 21425. The number of gripping cylinders 21431 matches the number of inserts 3 transferred in one operation, preferably four. The gripping cylinders 21431 are arranged vertically downward, and their grippers are designed for the opening structure of the end 32 of the insert 3, and are used to clamp the insert 3 from the outer periphery of the end 32, so as to avoid damaging the surface of the insert and ensure stable clamping, thus completely solving the technical problem that the vacuum nozzle cannot adsorb the opening of the end 32 of the insert 3.

[0036] To ensure the accuracy of the rotation position, springs are provided on both sides of the rotating component 21412 and between it and the moving unit 2142. These springs are used for buffering and positioning after the rotation is completed, to prevent overshoot and offset of the insert.

[0037] The transfer fixture placement unit 2144 is used for the rotary gripping module 214 to insert or remove the insert 3 from the transfer fixture 211. It includes a vertical plate 21441, a support plate 21442, a concave plate 21443, and a locking cylinder 21444. The vertical plate 21441 is vertically mounted on the mounting plate 212, the support plate 21442 is horizontally fixed to the upper end of the vertical plate 21441, and the concave plate 21443 is fixed to the support plate 21442. The locking cylinder 21444 is mounted on the outside of the concave plate 21443 and is used to lock or release the transfer fixture 211 placed within the concave plate 21443 through the concave plate. The transfer fixture 211 has an insertion hole 2111 for the rotating clamping module 214 to insert the insert 3. A connecting block 2112 is provided on one side of the fixture. The connecting block 2112 has through grooves 21121 on opposite sides, which can be understood as the upper and lower end faces, so as to facilitate the clamping of the fixture transfer injection molding mechanism 22.

[0038] like Figure 7 As shown, the jig transfer injection molding mechanism 22 is used to move the transfer jig 211 containing the insert 3 to be processed to the mold for injection molding, or to return the transfer jig 211 containing the overmolded insert 3 after injection molding to the initial position of the transfer jig placement unit 2144. It includes a rotating cylinder 221, a rotating frame 222, and a jig clamping unit 223.

[0039] Rotary cylinder 221 is connected to an external robotic arm (not shown in the figure), and under the drive of the robotic arm, it can move or rotate as a whole, adapting to the position conversion between the mold and the transfer fixture placement unit 2144. Rotary frame 222 is connected to the output end of rotary cylinder 221, and can rotate 180° under the drive of rotary cylinder 221 to realize the reversal of transfer fixture 211 and improve the continuity of operation.

[0040] The jig gripping unit 223 is installed inside the rotating frame 222 and includes a first gripping unit 2231, a second gripping unit 2232, a guide assembly 2233, and a drive cylinder unit 2234. The gripping directions of the first gripping unit 2231 and the second gripping unit 2232 are opposite. Both are connected to the rotating frame 222 by the guide assembly 2233. The guide assembly 2233 includes at least two parallel guide rods, which are fixed to the rotating frame 222 and pass through the first gripping unit 2231 and the second gripping unit 2232 to ensure smooth movement of the gripping units. A linkage block is also connected between the first gripping unit 2231 and the second gripping unit 2232. When the drive cylinder unit 2234 drives the first gripping unit 2231 to move, the linkage block can drive the second gripping unit 2232 to move synchronously along the guide assembly 2233, realizing the coordinated action of the two gripping units.

[0041] The first gripping unit 2231 includes a support plate 1, a support plate 2, and a gripper cylinder 1 located between the support plate 1 and the support plate 2. The second gripping unit 2232 includes a support plate 3 22321, a support plate 4 22322, and a gripper cylinder 22323 located between the support plate 3 22321 and the support plate 4 22322. The gripper shapes of the gripper cylinders 1 and 22323 are adapted to the grooves 21121 of the connecting block 2112 of the transfer fixture 211 to ensure stable gripping. The drive cylinder unit 2234 is provided with at least two drive cylinders 22341. The two drive cylinders 22341 are respectively connected to the support plate 1 and the rotating frame 222, and the support plate 2 and the rotating frame 222, and are used to drive the first gripping unit 2231 to move along the guide direction of the guide assembly 2233. At the same time, the second gripping unit 2232 is driven to move synchronously through the linkage block to realize the alternating picking and placing of the transfer fixture 211. It should also be noted that the linkage block may be connected between the gripper cylinder of the first gripping unit and the gripper cylinder 22323 of the second gripping unit.

[0042] In a practical application scenario provided by this invention, the specific workflow of the fully automated insert embedding and molding device 100 is as follows: Equipment initialization: After power-on, all components of the device are reset to their initial positions. The transfer fixture 211 is placed on the concave plate 21443 of the transfer fixture placement unit 2144. The locking cylinder 21444 locks the transfer fixture 211. The external robot arm drives the fixture transfer injection molding mechanism 22 to reset to its initial position close to the transfer fixture placement unit 2144. The first gripping unit 2231 and the second gripping unit 2232 are in the open state.

[0043] Loading of inserts to be processed: The lifting and gripping cylinder module 181 of the insert pallet conveying mechanism 18 is activated, lowering a pallet 14 onto the conveyor belt. The pallet 14 is loaded with several inserts 3 arranged side by side. The conveyor belt operates, driving the pallet 14 towards the insert clamping mechanism 12. When the pallet 14 reaches the working position of the insert clamping mechanism 12, the fourth lifting cylinder 1252 of the pallet blocking unit 125 drives the blocking plate 1253 to rise, preventing the pallet 14 from moving further and achieving precise positioning of the pallet 14.

[0044] Insert transfer to intermediate transfer fixture: The linear drive module 121 and linear drive module 223 of the insert clamping mechanism 12 work together to drive the insert moving unit 124 to move above the tray 14. The third lifting cylinder 1241 drives the gripping fixture 1242 to descend. The contour block fits against the rod 31 of the insert 3, and the vacuum suction hole generates negative pressure to adsorb the insert 3, clamping 4 inserts 3 at a time. Then the third lifting cylinder 1241 rises, and the linear drive module 121 and linear drive module 223 work to drive the insert moving unit 124 to move above the intermediate transfer fixture 2133 of the insert receiving module 213. The suction stops, and the insert 3 is placed into the placement slot 21331 of the intermediate transfer fixture 2133. At the same time, the rotating component 21412 of the rotating unit 2141 rotates 70° clockwise under the drive of the rotating motor 21411 to prepare for receiving the insert 3.

[0045] Insert transfer to transfer fixture: Linear drive module 3 2131 drives placement plate 2132 and intermediate transfer fixture 2133 to move below rotary clamping module 214. Rotary motor 21411 of rotating unit 2141 drives rotating shaft 21423 of rotating component 21412 to rotate 20° clockwise. First drive cylinder 21423 and second drive cylinder 21424 of moving unit 2142 are activated, driving moving plate - 21425 to move along the guiding direction of first guide rod 21421 and second guide rod 21422, so that clamping cylinder 21431 of clamping unit 2143 is aligned with end 32 of insert 3 inside intermediate transfer fixture 2133. Subsequently, the rotating unit 2141 rotates 20° counterclockwise, and the suction unit 2143 and the four inserts 3 move diagonally upwards and to the right. The rotating unit 2141 then rotates 70° counterclockwise again, causing the suction unit 2143 and the inserts 3 to rotate above the transfer fixture 211, perpendicular to the linear drive module 2131. The moving unit 2142 drives the moving plate 21425 to descend, the gripper of the clamping cylinder 21431 opens, releasing the inserts 3 and precisely inserting them into the insertion holes 2111 of the transfer fixture 211, completing the transfer loading of the inserts 3 and forming the first transfer fixture filled with inserts. Then, the suction unit 2143 moves upwards, moving away from the inserts 3.

[0046] During this process, the linear drive module 2131 drives the placement plate 2132 and the intermediate transfer fixture 2133 back to their initial positions, allowing the lifting and gripping cylinder module 181 of the insert tray conveying mechanism 18 to place the next set of inserts into the placement slot 21331 of the intermediate transfer fixture 2133. The intermediate transfer fixture 2133 then moves back to the side of the rotating unit 2141 to prepare for the next insert transfer.

[0047] The transfer fixture is transferred to the mold for injection molding: The external manipulator of the fixture transfer injection molding mechanism 22 is activated, driving the rotating cylinder 221 and the rotating frame 222 to move to the transfer fixture placement unit 2144; the driving cylinder 22341 of the driving cylinder unit 2234 extends, driving the first gripping unit 2231 to move along the guide assembly 2233 towards the transfer fixture 211, and the gripper of the first gripper cylinder opens and clamps the groove 21121 of the connecting block 2112 of the first transfer fixture 211; the locking cylinder 21444 of the transfer fixture placement unit 2144 retracts, releasing the first transfer fixture manipulator and driving the first transfer fixture 211 with the insert 3 to move into the molding machine mold for injection molding and overmolding.

[0048] Furthermore, after the drive cylinder 22341 extends to grip the transfer fixture 211 containing the insert 3, it retracts and drives the rotating frame to rotate 180° via the rotation cylinder 221, causing the second gripping unit 2232, which faces the opposite direction, to extend. The empty second transfer fixture 211 is placed into the concave plate 21443 of the transfer fixture placement unit 2144. The locking cylinder 21444 extends to lock the empty transfer fixture, preparing for the loading of the next set of inserts 3, thus forming a second transfer fixture 211 filled with inserts.

[0049] Then, the first gripping unit of the robotic arm places the first transfer fixture 211 filled with inserts into the molding machine mold, and then grips the empty third transfer fixture 211 next to the concave plate 21443 of the transfer fixture placement unit 2144. Subsequently, the robotic arm drives the rotating frame to rotate 180° through the rotating cylinder, and the second gripping unit removes the second transfer fixture 211 filled with inserts. The first gripping unit 2231 places the empty third transfer fixture 211 into the concave plate 21443 of the transfer fixture placement unit 2144. The next set of inserts is then placed into the third empty transfer fixture using the same method, forming the third transfer fixture 211 filled with inserts.

[0050] After injection molding is completed, the transfer fixture returns: After injection molding is completed, the robot arm extends into the mold, the first gripping unit clamps the first transfer fixture 211 containing the overmolded finished insert 3, and removes it from the mold; then the robot arm gripper rotates 180°, and the second gripping unit puts the second transfer fixture 211 filled with inserts into the molding machine mold for injection molding.

[0051] The robotic arm returns to the transfer fixture placement unit 2144 with the transfer fixture containing the overmolded finished insert 3. The second gripping unit first takes out the third transfer fixture 211 filled with inserts from the transfer fixture placement unit. The rotating cylinder 221 of the robotic arm rotates 180°. The first gripping unit puts the first transfer fixture 211 containing the overmolded finished insert 3 into the transfer fixture placement unit 2144. The second gripping unit leaves the transfer fixture placement unit 2144 with the third transfer fixture 211 filled with inserts, waiting for injection molding.

[0052] The coated finished insert 3 is transferred to the tray 14: the moving unit 2142 drives the gripping unit 2143 to descend, and the gripper of the gripper cylinder 21431 clamps the coated finished insert 3 inside the first transfer fixture 211; the moving unit 2142 rises, and the rotating unit 2141 drives the rotating component 21412 to rotate 70°, and the gripping unit 2143 and the insert 3 move diagonally downward to the left to above the insert receiving module 213; the rotating unit 2141 rotates clockwise again by 20°, parallel to the insert receiving module 213, the gripper of the gripper cylinder 21431 releases the insert, and the gripping unit 2143 moves backward via the moving unit 2142. The rotating unit 2141 rotates counterclockwise by 20°, and the insert receiving module 213 returns to its original position.

[0053] The insert moving unit 124 of the insert clamping mechanism 13 operates (consistent with the operation of the insert clamping mechanism 12), and the rod 31 of the coated finished insert 3 is transferred to the empty pallet 14 on the downstream conveyor belt by the conforming block fitting and vacuum adsorption. When the finished products in the receiving product pallet 14 reach the set quantity and the pallet below the insert pallet conveying mechanism 18 is emptied, the conveyor belt runs, and the pallet 14 moves to the insert storage pallet mechanism 19. The insert clamping cylinder module 191 of the insert storage pallet mechanism 19 operates, and the second lifting cylinder 1911 drives the clamping plate 1912 to lift the pallet. The pallet will only descend when a new pallet 14 containing finished products is delivered to the insert storage pallet mechanism 19. During the descent, the lifted pallet is placed on the new pallet below, and the clamping plate 1912, with the arc-shaped locking block, descends to the bottom edge of the pallet, and then lifts all the pallets together.

[0054] In addition, the first transfer fixture 211 becomes an empty transfer fixture after the coated finished insert 3 is removed, and continues to be used to load new inserts 3 to be processed, thus achieving uninterrupted circulation.

[0055] Cyclic operation: The subsequent device continuously repeats the above process. Through the alternating action of the first clamping unit 2231 and the second clamping unit 2232, and the cyclic use of the three transfer fixtures, the entire process of insert loading, transfer, injection molding and finished product collection is fully automated and continuous, without the need for manual intervention.

[0056] This invention improves the traditional fully automatic device by replacing the suction unit with a clamping unit. By using a clamping cylinder to clamp the insert from the outer periphery of the end 32, it successfully solves the technical problem that inserts with openings at the end 32 cannot be transferred by vacuum adsorption, significantly improving the device's adaptability to inserts with different structures. At the same time, it maintains the automation process and high-efficiency operation advantages of the original device, ensuring that production efficiency and safety are not affected. It is suitable for injection molding production of various inserts with openings at the end 32 or tubular end 32 structures, and has broad application prospects.

Any equivalent structural or procedural transformations made based on the content of the present invention's specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of the present invention.
