Description

Technical Field

[0001] This utility model relates to the technical field of spring feeding, and in particular to a spring feeding device. Background Technology

[0002] As the name suggests, a spring feeding device is an automated feeding device that feeds springs and positions them for the next assembly station.

[0003] Current spring feeding devices include, for example, the combination of spring feeding device, spring positioning and guiding device, spring misalignment and material distribution device, and spring clamping and insertion device in a Chinese utility model patent with patent document number CN207104270U and patent name: a spring feeding and assembly mechanism for a straight-through terminal block.

[0004] Current shrapnel feeding devices can be categorized into two types:

[0005] 1. Spring feeding + positioning sensor + single spring misalignment and material separation device: first separate the single springs, and then use a robotic arm to clamp the single springs away for assembly;

[0006] 2. Spring feeding + single spring gripping device + single spring misalignment and material distribution device (as described in the above patent): first, the single spring is picked up into the single spring groove, then the single spring is separated, and finally the single spring is clamped away by a robotic arm for assembly.

[0007] However, the current shrapnel feeding device has the following drawbacks:

[0008] The manufacturing cost is relatively high. The above-mentioned positioning sensor + single spring misalignment material distribution (requiring the use of one cylinder) or single spring gripping + single spring misalignment material distribution (requiring the use of two cylinders) will increase the manufacturing cost. Utility Model Content

[0009] The purpose of this utility model is to overcome the above-mentioned defects in the prior art and provide a spring feeding device that completes the single spring removal by the cooperation of a linear vibrator, a feeding robot and a blocking mechanism. The blocking mechanism is a purely mechanical structure with a simple structure and no electrical components involved, thereby effectively reducing the manufacturing cost of the spring feeding device.

[0010] To achieve the above objectives, this utility model provides a spring feeding device, including a linear vibrator for transporting springs, a feeding robot below the linear vibrator, a first picking groove at one end of the linear vibrator, the feeding robot including a horizontal module, a lifting module mounted on the horizontal module and reciprocating along the direction of the first picking groove, and a picking arm mounted on the lifting module, the picking arm including a picking block for inserting into the first picking groove to pick up the spring and a first top block mounted on one side of the picking block, a blocking mechanism at one end of the linear vibrator, the blocking mechanism including a mounting base, a stop block slidably connected to the mounting base, and a return spring mounted between the mounting base and the stop block, the stop block abutting against one end of the linear vibrator and cooperating with the first top block of the picking arm.

[0011] Preferably, the mounting base includes a main mounting block installed on one side of one end of the linear vibrator. The main mounting block has a sliding slot for sliding the stop block and a placement groove for placing the reset spring. An upper fixing block is installed on the top of the main mounting block and a lower fixing block is installed on the bottom of the main mounting block.

[0012] Preferably, the reset spring abuts between the bottom of the upper fixing block and the top of the stop block.

[0013] Preferably, the stop block has a second top block that cooperates with the first top block of the picking arm. The stop block is provided with a first clearance groove to avoid collision with the picking block when the picking block of the picking arm moves laterally. One end of the first clearance groove is provided with a first stop block part for blocking the first part of the spring piece, and the other end is provided with a second stop block part for blocking the second part of the spring piece.

[0014] Preferably, the linear vibrator has a second material picking groove at one end, and the material picking block of the material picking arm has a material picking clamping part on one side for inserting into the second material picking groove and for engaging with one end of the spring piece. The stop block has a second clearance groove to avoid collision with the material picking clamping part when the material picking block of the material picking arm moves laterally.

[0015] Preferably, a vibratory feeding tray is also included at one end of the linear vibrator.

[0016] Preferably, the linear vibrator includes a vibration source and a vibration table mounted on the vibration source. The vibration table includes a lower transport seat and an upper pressure seat mounted on top of the lower transport seat. A transport groove for linear transport of the spring sheet is provided between the lower transport seat and the upper pressure seat. The first material pick-up groove is located at one end between the lower transport seat and the upper pressure seat.

[0017] Preferably, the linear vibrator has a guide groove at one end, and the material picking block of the picking arm has a guide slider that is slidably connected to the guide groove at one end.

[0018] Preferably, the horizontal module and the lifting module are respectively a slide table or a cylinder or a combination of a cylinder and a slide rail slider, or a combination of a rotary motor, a synchronous pulley and synchronous belt, and a slide rail slider, or a combination of a rotary motor, a lead screw, and a slide rail slider.

[0019] Preferably, an angle connecting block is provided between the horizontal module and the lifting module to adapt the lifting module to the direction of the first material receiving slot.

[0020] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0021] 1. Effectively reduce manufacturing costs and enhance the product competitiveness of the spring feeding device:

[0022] The picking block of the picking arm of the feeding robot directly picks up the spring piece from the first picking slot of the linear vibrator. During the picking process, the first top block of the picking arm lifts the stop block of the blocking mechanism, so that the single spring piece can be picked up smoothly. After the picking is done, the stop block is reset by the reset spring and blocks one end of the linear vibrator.

[0023] Therefore, the outstanding advantage of this spring sheet feeding device is that it completes the single spring sheet removal by the cooperation of a linear vibrator, a feeding robot and a blocking mechanism. The blocking mechanism is a purely mechanical structure with a simple structure and no electrical components involved, thereby effectively reducing the manufacturing cost of the spring sheet feeding device.

[0024] 2. Effectively reduces the space occupied by the spring feeding device, which is beneficial for the handling of the spring feeding device and the layout of the factory:

[0025] The feeding robot of this invention directly connects to one end of the linear vibrator to remove the spring sheet, thereby eliminating the need for the installation space of the existing single spring sheet misalignment and distribution device, and thus reducing the space occupied by the spring sheet feeding device.

[0026] 3. Effectively improves the feeding efficiency of the spring feeding device;

[0027] The feeding robot of this invention directly connects to one end of the linear vibrator to pick up the spring sheet, thereby saving the time of single spring sheet misalignment and material distribution of the existing single spring sheet misalignment and material distribution device, thus improving the feeding efficiency.

[0028] 4. Effectively improves feeding accuracy;

[0029] By having the picking block of the feeding robot arm directly align with the first picking slot of the linear vibrator to pick up the spring sheet, the feeding accuracy of the spring sheet can be guaranteed. Attached Figure Description

Detailed Implementation

[0042] The technical solution of this embodiment of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiment is one embodiment of the present invention, and not all embodiments thereof. Based on this embodiment of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0043] Please see Figures 1 to 9 An embodiment of this utility model provides a spring sheet feeding device, including a linear vibrator for transporting spring sheets 4. A feeding robot 3 is provided below the linear vibrator. A first picking groove 124 is provided at one end of the linear vibrator. The feeding robot 3 includes a horizontal module 31, a lifting module 32 mounted on the horizontal module 31 and reciprocating along the direction of the first picking groove 124, and a picking arm 33 mounted on the lifting module 32. The picking arm 33 includes a picking block 331 for inserting into the first picking groove 124 to pick up the spring sheet 4 and a first top block 333 mounted on one side of the picking block 331. A blocking mechanism 2 is provided at one end of the linear vibrator. The blocking mechanism 2 includes a mounting base 21, a blocking block 23 slidably connected to the mounting base 21, and a return spring 22 mounted between the mounting base 21 and the blocking block 23. The blocking block 23 abuts against one end of the linear vibrator and cooperates with the first top block 333 of the picking arm 33.

[0044] The first material picking groove 124 corresponds to the groove of the spring piece 4. When picking up material, the material picking block 331 is inserted into the first material picking groove 124 and simultaneously into the groove of the spring piece 4, thereby removing the spring piece 4.

[0045] Mounting base 21 includes a main mounting block 212 mounted on one side of one end of the linear vibrator. The main mounting block 212 has a sliding slot 2121 for sliding the stop block 23, and a placement groove 2122 for placing the return spring 22. An upper fixing block 211 is mounted on the top of the main mounting block 212, and a lower fixing block 213 is mounted on the bottom of the main mounting block 212. The upper fixing block 211 and the lower fixing block 213 work together to restrict the stop block 23 to move only on the sliding slot 2121.

[0046] The return spring 22 abuts against the bottom of the upper fixing block 211 and the top of the stop block 23.

[0047] The stop block 23 has a second top block 235 that cooperates with the first top block 333 of the picking arm 33. The stop block 23 has a first clearance groove 233 for avoiding collision with the picking block 331 when the picking arm 33 moves laterally. One end of the first clearance groove 233 is provided with a first stop block 23 for blocking the first part 41 of the spring piece 4, and the other end is provided with a second stop block 23 for blocking the second part 42 of the spring piece 4.

[0048] The linear vibrator has a second feeding groove 125 at one end, which corresponds to one end of the spring piece 4. The feeding block 331 of the feeding arm 33 has a feeding latching part 332 on one side for inserting into the second feeding groove 125 and for engaging with one end of the spring piece 4. The stop block 23 has a second clearance groove 234 for avoiding collision with the feeding latching part 332 when the feeding block 331 of the feeding arm 33 moves laterally.

[0049] An embodiment of the present invention provides a spring feeding device that further includes a vibrating feeding plate (not shown in the accompanying drawings) installed at one end of a linear vibrator.

[0050] The linear vibrator includes a vibration source (not shown in the attached drawings) and a vibration table 12 mounted on the vibration source. The vibration table 12 includes a lower transport seat 121 and an upper pressure seat 123 mounted on the top of the lower transport seat 121. A transport groove 122 for linear transport of the spring piece 4 is provided between the lower transport seat 121 and the upper pressure seat 123. A first material pick-up groove 124 is provided at one end between the lower transport seat 121 and the upper pressure seat 123.

[0051] One end of the linear vibrator is provided with a guide groove 127, and one end of the material taking block 331 of the material taking arm 33 is provided with a guide slider 334 that is slidably connected to the guide groove 127.

[0052] The horizontal module 31 and the lifting module 32 are respectively a slide table or a cylinder or a combination of a cylinder and a slide rail slider, or a combination of a rotary motor, a synchronous pulley and a synchronous belt, and a slide rail slider, or a combination of a rotary motor, a lead screw, and a slide rail slider.

[0053] An angle connecting block 311 is provided between the horizontal module 31 and the lifting module 32 to adapt the lifting module 32 to the direction of the first material receiving slot 124.

[0054] The working principle of a spring feeding device according to an embodiment of this utility model is as follows:

[0055] S1: In the initial state, the vibrating feeder vibrates the individual spring pieces 4 into the transport groove 122 of the linear vibrator. The lower transport seat 121 and the upper pressure seat 123 position the spring pieces 4. The vibration source transports the individual spring pieces 4 along the transport groove 122. The return spring 22 of the baffle mechanism 2 pushes the baffle block 23 downward, so that the first baffle block 23 part of the baffle block 23 is used to block the first part 41 of the spring piece 4, and the second baffle block 23 part of the baffle block 23 is used to block the second part 42 of the spring piece 4, thereby blocking a single spring piece 4 at one end of the linear vibrator.

[0056] S2: When the loading robot 3 loads a single spring piece 4, the horizontal module 31 drives the lifting module 32 to approach the linear vibrator. The function of the angle connecting block 311 is to adjust the connection and installation angle of the lifting module 32 so that the lifting direction of the lifting module 32 is aligned with the direction of the first picking groove 124. The lifting module 32 drives the picking arm 33 to move along the direction of the first picking groove 124. During this period, the guide slider 334 of the picking arm 33 enters the guide groove 127 and slides along the guide groove 127, so that the picking arm 33 picks up the material more smoothly and accurately.

[0057] S3: During the movement of the picking arm 33 along the direction of the first picking groove 124, the picking block 331 of the picking arm 33 enters the first picking groove 124 and is inserted into the groove of the single spring piece 4. The picking clamping part 332 of the picking arm 33 enters the second picking groove 125 and is clamped to one end of the single spring piece 4, thereby realizing that the picking arm 33 can clamp the single spring piece 4.

[0058] S4: During the execution of step S3, simultaneously, the first top block 333 of the picking arm 33 abuts against the second top block 235 of the stop block 23, and the picking arm 33 pushes the stop block 23 upward, causing the stop block 23 to slide upward, thereby causing the first stop block 23 part of the stop block 23 to leave the first part 41 of the spring piece 4 and the second stop block 23 part of the stop block 23 to leave the second part 42 of the spring piece 4, so that the stop block 23 no longer blocks the spring piece 4;

[0059] S5: The horizontal module 31 drives the lifting module 32 away from the linear vibrator. During this period, the first clearance groove 233 avoids collision with the material picking block 331, and the second clearance groove 234 avoids collision with the material picking clamp 332.

[0060] The instant a single spring piece 4 leaves one end of the linear vibrator, the return spring 22 of the stop mechanism 2 pushes the stop block 23 downward, thereby restoring it to the initial state of S1, so that the stop block 23 blocks the next spring piece 4.

[0061] The advantages of a spring feeding device according to an embodiment of this utility model are as follows:

[0062] 1. The single removal of the spring piece 4 is completed by the cooperation of the linear vibrator, the feeding robot 3 and the blocking mechanism 2. The blocking mechanism 2 does not involve electrical components and is a purely mechanical structure, which can effectively reduce its manufacturing cost.

[0063] 2. The material blocking mechanism 2 occupies little space, thus effectively reducing the space occupied by the spring sheet 4 feeding device, which is beneficial for the handling of the spring sheet 4 feeding device and the layout of the factory.

[0064] 3. The feeding robot 3 directly removes a single spring piece 4 from one end of the linear vibrator, which has high feeding efficiency;

[0065] 4. The feeding robot 3 directly picks up a single spring piece 4 from one end of the linear vibrator. The first picking groove 124 directly cooperates with the picking block 331, and the second picking groove 125 directly cooperates with the picking clamp 332, which effectively improves the feeding accuracy.

[0066] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
