Description

Technical Field

[0001] The invention relates to the technical field of terminal processing, in particular to a connector terminal blanking and packaging device. Background Art

[0002] The connector terminal is a part of the connector, used to connect wires or cables. The terminal is usually made of metal. It has the function of inserting and fixing the wires to ensure reliable electrical connection and the ability to transmit signals and power. After the production is completed, the connector terminal usually needs to be packaged. Fig.13 As shown, a common way of packaging connector terminals is a rectangular material strip with evenly spaced notches on the material strip. The connector terminals are placed into each notch of the material strip and then the notches of the material strip are packaged to complete the packaging of the connector terminals. This packaging method is more convenient for storage and transportation of connector terminals.

[0003] Existingly, when cutting and packaging connector terminals, a roller-type cutting mechanism is usually used to intermittently cut the terminals after production is completed, and at the same time, a conveyor belt is controlled to drive the material belt to move synchronously at intervals, so that the roller-type cutting mechanism cuts the terminals into each notch of the material belt, and finally the notches of the material belt are sealed to complete the cutting and packaging of the connector terminals.

[0004] The following problems exist in the existing process of cutting and packaging connector terminals: 1. When the connector terminals are cut intermittently, the connector terminals may tilt, causing the connector terminals to be cut obliquely into the notches of the material strip, and then when the notches of the material strip are packaged, the tilted connector terminals may damage the packaging materials, thereby affecting the packaging quality of the connector terminals after packaging is completed; 2. When the connector terminals are cut intermittently into the notches of the material strip, the connector terminals may not be able to completely fall into the notches of the material strip, and the position of the connector terminals needs to be manually adjusted, resulting in reduced packaging efficiency for the connector terminals.

[0033] The embodiments described below are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention. If no specific techniques or conditions are specified in the embodiments, the techniques or conditions described in the literature in the art or the product instructions shall be followed.

[0034] See also Figure 1 A connector terminal blanking and packaging device includes a conveying unit 1, a blanking unit 2 is installed on the upper end of the conveying unit 1, a toggle unit 3 is installed on the upper end of the conveying unit 1 and on the right side of the blanking unit 2, and the conveying unit 1 is used to drive the material belt to move intermittently to the right.

[0035] It should be noted that, after the terminals are placed in the slots of the material strip, a sealing device is required to seal the material strip to complete the packaging operation of the terminals. The sealing device in the present invention adopts the existing technology to realize the sealing operation of the material strip. The sealing device can press the packaging material used for sealing the material strip on the upper end of the material strip, and then roll the packaging material, so that the packaging material is firmly pressed on the material strip to complete the sealing operation of the material strip.

[0036] The present invention can intermittently unload the terminals and synchronously drive the material belt to move intermittently, thereby unloading the terminals into each slot in turn, and at the same time the present invention can completely push the terminals into the slots of the material belt, thereby eliminating the need for manual position adjustment of the terminals that have not completely fallen into the slots, thereby increasing the packaging efficiency of the terminals; specifically, the terminals are placed in the unloading unit 2, and the material belt is placed on the conveying unit 1, the unloading unit 2 is started to unload the terminals intermittently, and at the same time the conveying unit 1 is started to drive the material belt to move synchronously and intermittently, so that the unloading unit 2 unloads the terminals into each slot of the material belt in turn, and at the same time the toggle unit 3 is started to continuously toggle the upper end of the material belt, thereby enabling the toggle unit 3 to toggle the terminals that have not completely fallen into the slots into the slots, and finally the material belt is sealed by a subsequent sealing device, thereby completing the unloading and packaging of the terminals.

[0037] See also Figure 1-Figure 5 The conveying unit 1 includes a U-shaped seat 11, and the unloading unit 2 includes a cylinder 21 distributed above the U-shaped seat 11. The lower parts of the front and rear sides of the cylinder 21 are fixedly connected to the U-shaped seat 11 through L-shaped plates 28. A loading cylinder 22 with its upper end tilted to the left is installed on the upper left of the cylinder 21, and a unloading cylinder 23 with its lower end tilted to the right is installed on the lower right of the cylinder 21. A turntable 24 is rotatably installed in the cylinder 21, and a driving member 25 is installed in the middle of the rear end of the turntable 24. A plurality of storage grooves 26 evenly distributed along its circumference are provided on the outer side of the turntable 24, and a clamping mechanism 27 for preventing the terminal from tilting is installed in the storage groove 26.

[0038] It should be noted that the driving member 25 in the present invention uses a motor to drive the turntable 24 to rotate. The driving member 25 includes a rotating shaft fixedly installed in the middle of the rear end of the turntable 24. The rear end of the rotating shaft passes through the cylinder 21 and is fixedly connected to the output shaft of the motor fixedly installed on the rear L-shaped plate 28.

[0039] The unloading unit 2 is used for intermittent unloading of terminals; specifically, the finished terminals are placed from the upper barrel 22, and the terminals can enter the cylinder 21 along the upper barrel 22 and rest on the turntable 24. The driving member 25 is started to drive the turntable 24 to rotate to the right. When the material storage groove 26 on the turntable 24 rotates to the corresponding position of the upper barrel 22, the terminal can move into the material storage groove 26, and the clamping mechanism 27 can clamp the terminal. When the turntable 24 drives the material storage groove 26 to rotate to the corresponding position of the unloading barrel 23, the clamping mechanism 27 can release the terminal at this time, and the terminal can move into the unloading barrel 23 under the action of gravity, and move out along the unloading barrel 23, thereby realizing intermittent unloading of the terminal.

[0040] It should be noted that when the terminals are moved from the loading barrel 22 to the cylinder 21 , the size of the loading barrel 22 only allows the terminals to pass through in a single row, thereby preventing the terminals from being piled up together and allowing the terminals to enter the storage slots 26 of the turntable 24 in sequence.

[0041] See also Figure 5-Figure 7 The clamping mechanism 27 includes two symmetrically arranged clamping plates 271 distributed in the material storage trough 26, and the two clamping plates 271 are distributed along the circumference of the turntable 24. The ends of the two clamping plates 271 away from each other are fixedly installed with a plurality of evenly arranged extension rods 272, and the ends of the extension rods 272 away from the clamping plates 271 are slidably connected to the turntable 24 through extension springs 273; the ends of the clamping plates 271 close to the center line of the turntable 24 are fixedly installed with L-shaped matching rods 274, and the matching rods 274 are slidably connected to the turntable 24, and the rear end of the matching rods 274 passes through the turntable 24, and the rear side of the turntable 24 is slidably installed with a plurality of evenly distributed extension rods 272 along its circumference through the return spring 242. The mating block 241 has a one-to-one correspondence with the installation position of the mating block 241 and the position of the material storage slot 26. The end of the mating block 241 away from the center line of the turntable 24 is set to a trapezoidal structure, and the mating block 241 is used to drive the two corresponding mating rods 274 to move in a direction away from each other; a lifting column 243 is installed at the rear end of the mating block 241, and an arc-shaped lifting block 211 is installed at the corresponding position of the inner wall of the rear side of the cylinder 21 and the upper barrel 22 and the lower barrel 23. The lifting block 211 is provided with an inclined surface on the side opposite to the rotation direction of the turntable 24. The lifting block 211 is used to cooperate with the lifting column 243 to drive the mating block 241 to move in a direction away from the center line of the turntable 24.

[0042] The clamping mechanism 27 is used to clamp the terminals to prevent the terminals from tilting when the terminals are intermittently unloaded, thereby preventing the terminals from being tilted into the slots of the material strip, causing the terminals to damage the packaging materials of the packaging slots, thereby increasing the packaging quality of the terminals; specifically, when the material storage slot 26 of the turntable 24 rotates to the corresponding position of the upper barrel 22, the matching block 241 corresponding to the material storage slot 26, under the coordinated action of its corresponding lifting column 243 and the inclined surface of the lifting block 211 corresponding to the upper barrel 22, enables the lifting column 243 to drive the matching block 241 to move away from the center line of the turntable 24, so that the lifting column 243 can drive its corresponding two matching rods 274 to move away from each other, thereby causing the two clamping plates 271 in the material storage slot 26 to move away from each other, so that the terminal can move between the two clamping plates 271.

[0043] When the turntable 24 drives the material storage trough 26 to continue to rotate to the right, the lifting column 243 corresponding to the material storage trough 26 and the lifting block 211 corresponding to the loading barrel 22 are separated, so that the matching block 241 returns to the initial position under the action of the reset spring 242. At the same time, the two clamping plates 271 move toward each other under the action of the extension spring 273 and the extension rod 272, so that the two clamping plates 271 can stably clamp the terminals, thereby preventing the terminals in the material storage trough 26 from tilting when the turntable 24 rotates.

[0044] When the turntable 24 drives the material storage trough 26 to rotate to the corresponding position of the discharge barrel 23, the matching block 241 corresponding to the material storage trough 26, through the corresponding lifting column 243 and the inclined surface of the lifting block 211 corresponding to the discharge barrel 23, makes the two clamping plates 271 move away from each other again, so that the terminal can be moved out of the material storage trough 26 and out of the discharge barrel 23.

[0045] See also Figure 1 , Figure 2 and Fig. 9 The conveying unit 1 also includes a stepping conveyor belt 12 installed in the U-shaped seat 11. Fixed rods 13 are fixedly installed on the upper sides of the two vertical sections of the U-shaped seat 11. A plurality of left-right evenly arranged alignment rods 15 are installed on the opposite sides of the two fixed rods 13 for sliding back and forth through alignment springs 14. A guide wheel 16 is rotatably installed on the side of the alignment rod 15 away from its corresponding fixed rod 13.

[0046] It should be noted that the side of the stepping conveyor belt 12 away from the rotation axis is made of a material with greater friction, so that the stepping conveyor belt 12 can stably drive the material belt to move intermittently to the right.

[0047] The conveying unit 1 is used for intermittently conveying the material belt; specifically, the material belt is placed on the stepping conveyor belt 12, at which time the upper end of the material belt and the upper end of the fixed rod 13 are on the same horizontal plane, and the stepping conveyor belt 12 is started to drive the material belt to move intermittently to the right. At the same time, the guide wheel 16 is pressed against the front and rear sides of the material belt under the action of the alignment rod 15 and the alignment spring 14, so that the material belt can be placed in the center on the stepping conveyor belt 12, and then the material belt and the turntable 24 are aligned in the center front and back, which is convenient for unloading the terminals into the slots.

[0048] See also Figure 1 , Figure 8 , Fig.10 and Fig.12 The toggle unit 3 includes a U-shaped plate 31 fixedly mounted on the upper end of the U-shaped seat 11, an electric push rod 32 is fixedly mounted on the inner wall of the U-shaped plate 31, a synchronous plate 33 is fixedly mounted on the lower end of the electric push rod 32, a square groove 34 is opened inside the left side of the synchronous plate 33, a transmission plate 36 is slidably mounted on the inner wall of the square groove 34 through a guide spring 35, a toggle plate 37 is fixedly mounted on the right side of the lower end of the transmission plate 36, the lower end of the toggle plate 37 is set as an elastic telescopic structure and a round rod 371 is rotatably mounted, and the lower end of the toggle plate 37 penetrates the synchronous plate 33 and is slidably connected to the synchronous plate 33, a pushing mechanism 38 for driving the transmission plate 36 to move rightward is installed on the left side of the synchronous plate 33, and a pressing mechanism 39 for pressing the terminal into the slot is installed on the right end of the lower side of the synchronous plate 33.

[0049] The toggle unit 3 is used to completely toggle the terminal into the slot of the material belt, so that there is no need for manual secondary adjustment of the terminal position, thereby increasing the terminal packaging efficiency; specifically, when the stepping conveyor 12 drives the material belt to move intermittently to the bottom of the synchronization plate 33, the electric push rod 32 is started to drive the synchronization plate 33 to move downward, and the synchronization plate 33 drives the toggle plate 37 to move downward through the transmission plate 36, so that the toggle plate 37 can fit on the upper end of the material belt, and at the same time, the pushing mechanism 38 can push the toggle plate 37 to move to the right, and the round rod 371 set at the lower end of the toggle plate 37 enables the toggle plate 37 to move smoothly to the right, so that the toggle plate 37 pushes the terminal completely into the slot of the material belt, and the pressing mechanism 39 can press the terminal completely into the slot, thereby increasing the sealing of the terminal after packaging is completed.

[0050] See also Figure 8-Figure 10The upper ends of the two fixed rods 13 are both slidably mounted with slide plates 132 through buffer springs 131, and the slide plates 132 are both located on the left side of the dial plate 37. Extrusion plates 133 are distributed on the opposite sides of the two slide plates 132. Square spring rods 134 are fixedly mounted on the ends of the two extrusion plates 133 that are away from each other, and the square spring rods 134 are slidably connected to the corresponding slide plates 132. Two square plates 331 symmetrically arranged front and back are fixedly mounted on the lower end of the synchronization plate 33. The opposite sides of the lower ends of the two square plates 331 are arranged as inclined surfaces for driving the two slide plates 132 to move in a direction close to each other.

[0051] When the synchronization plate 33 moves downward, the synchronization plate 33 drives the two square plates 331 to move downward, so that the inclined surfaces of the two square plates 331 drive the corresponding slide plates 132 to move towards each other, and then the slide plates 132 drive the two extrusion plates 133 to move towards each other through the square spring rods 134, and further enable the extrusion plates 133 to adjust the terminals that have not completely fallen into the slots, so that the front and rear positions of the terminals are aligned with the front and rear positions of the slots, thereby facilitating the subsequent dial plate 37 to push the terminals into the slots.

[0052] See also Figure 8 and Figure 10-12 The pushing mechanism 38 includes a pushing plate 381 which is slidably installed on the left inner wall of the square groove 34. A downward pressure spring 382 is connected between the pushing plate 381 and the synchronous plate 33. Two square rods 383 arranged symmetrically front and back are fixedly installed on the left end of the lower side of the pushing plate 381. The right end of the upper side of the pushing plate 381 is set as an inclined surface, and the left side of the lower end of the transmission plate 36 is set as an inclined surface for cooperating with the pushing plate 381 to drive the transmission plate 36 to move rightward.

[0053] It should be noted that the installation position of the square rod 383 corresponds to the installation position of the fixing rod 13 , wherein the lower end of the square rod 383 is higher than the lower end of the dial plate 37 .

[0054] The pushing mechanism 38 is used to drive the paddle plate 37 to paddle the terminal into the notch of the material strip. Specifically, when the electric push rod 32 drives the synchronous plate 33 to move downward, the synchronous plate 33 drives the square rod 383 to move downward through the pushing plate 381. When the square rod 383 moves to the upper end of the fixed rod 13, the telescopic end of the lower end of the paddle plate 37 can be compressed a part, so that the round rod 371 can be stably attached to the upper end of the material strip. At the same time, the square rod 383 drives the pushing plate 381 to move upward under the blocking effect of the fixed rod 13, and the pushing plate The inclined surfaces of 381 and the transmission plate 36 cooperate to drive the transmission plate 36 to move to the right, thereby pushing the paddle plate 37 to push the terminal that has not completely fallen into the slot into the slot. When the electric push rod 32 drives the synchronization plate 33 to move upward to the initial position, the push plate 381 returns to the initial position under the action of the downward pressure spring 382, ​​and the transmission plate 36 returns to the initial position under the action of the guide spring 35, thereby enabling the paddle plate 37 to return to the initial position, so that the paddle plate 37 can continuously perform a paddle operation on the upper side of each slot on the material strip.

[0055] See also Fig.10 The pressing mechanism 39 includes two left and right pressing plates 391 slidably installed on the lower end of the synchronous plate 33, a connecting spring 392 is connected between the pressing plate 391 and the synchronous plate 33, the lower end of the pressing plate 391 is set as an elastic telescopic structure, and a smoothing rod 393 is rotatably installed on the lower end of the pressing plate 391.

[0056] It should be noted that the lower end of the lower pressing plate 391 is lower than the lower end of the shifting plate 37, and the length of the lower pressing plate 391 in the front-to-back direction is smaller than the length of the slot in the front-to-back direction, so that the lower pressing plate 391 can extend into the slot.

[0057] The pressing mechanism 39 is used to press the terminal completely into the slot of the material strip, so that the terminal can be placed flatly in the slot of the material strip, further improving the packaging quality of the terminal after packaging is completed; specifically, when the electric push rod 32 drives the synchronous plate 33 to move downward, the synchronous plate 33 drives the two lower pressing plates 391 to press into the slot of the material strip, and the lower end of the synchronous plate 33 is an elastic telescopic structure, so that the two lower pressing plates 391 can continuously press down the left and right ends of the terminal, and then the lower pressing plates 391 can synchronously flatten the terminal in the slot, so that the terminal is placed horizontally in the slot.

[0058] See also Fig.10 and Fig.11The front ends of the two lower pressure plates 391 are hinged with connecting rods 394, and the two connecting rods 394 are hinged with a connecting block 395 on the side away from the lower pressure plate 391, and the connecting block 395 and the synchronous plate 33 are connected for sliding forward and backward; a matching plate 372 is fixedly installed at the front end of the right side of the dial plate 37, and a corrugated hole 373 is opened on the matching plate 372, and a matching column 396 is fixedly installed at the lower end of the connecting block 395, and the matching column 396 is slidably installed in the corrugated hole 373, and the corrugated hole 373 is used to drive the matching column 396 to move forward and backward.

[0059] When the lower pressure plate 391 moves to the right, the lower pressure plate 391 drives the matching plate 372 to move to the right. At the same time, the corrugated hole 373 and the matching column 396 of the matching plate 372 cooperate to drive the connecting block 395 to move forward and backward. The connecting block 395 drives the two lower pressure plates 391 to move synchronously in the direction of approaching each other or moving away from each other through the connecting rod 394, so that the lower pressure plate 391 drives the smoothing rod 393 to press and smooth the terminals in the slots, so that the terminals can be placed more flatly in the slots, further increasing the packaging quality after the terminals are packaged.

[0060] In addition, it should be understood that although the present specification is described according to implementation modes, not every implementation mode contains only one independent technical solution. This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.
