[0016] Exemplary embodiments will now be described more fully with reference to the accompanying drawings. However, these exemplary embodiments can be implemented in many forms and should not be construed as limited to the embodiments set forth herein; rather, they are provided to make the invention more comprehensive and complete, and to fully convey the concept of the exemplary embodiments to those skilled in the art. The same reference numerals in the drawings denote the same or similar structures, and therefore repeated descriptions of them will be omitted.

[0017] The terms used to express position and direction in this invention are illustrated with reference to the accompanying drawings, but changes can be made as needed, and all such changes are included within the scope of protection of this invention.

[0018] Reference Figure 1-9 This invention discloses an automated assembly for a holder of metal needles, comprising: Positioning module 3 is used to correct the placement of the sheet-like cage. Positioning module 3 is used to clamp, restrict, and fix the two side walls of the cage from two directions to achieve a preset mechanical position.

[0019] A picking mechanism is provided to pick up the position-corrected cage and place it at a preset position. The picking mechanism can be a robotic arm or a linear module; this application takes a linear module as an example, and is not limited thereto.

[0020] The positioning retainer 5 has a correction station for correcting the position of the injection molded part, which has a plurality of arrayed and bent matrix-shaped metal needles.

[0021] The comb-tooth guiding mechanism 6 includes a comb-tooth limiting groove 63. The positioning retainer 5 carries the movement of the injection molded part, guiding the metal needles through the comb-tooth limiting groove 63 and arranging them. The retainer is then inserted into the metal needles by the pickup mechanism. The pickup mechanism stably inserts the bent metal needles of the injection molded part according to the insertion direction of the comb-tooth limiting groove, ensuring precise alignment of the metal needles in both directions. This reduces the positional deviation of the positioning retainer 5 during metal needle insertion, effectively preventing assembly damage or poor contact caused by misaligned metal needles, and ensuring the stability and reliability of subsequent circuit connections.

[0022] Another aspect of this invention discloses an automatic assembly device for retainers of metal needles, comprising: a loading station 11, a transport station 12, and a unloading station 13. The loading station 11, transport station 12, and unloading station 13 are connected by a transfer mechanism 7. The transfer mechanism 7 can transfer a tray for holding the retainers between the loading station 11 and the transport station 12, and between the transport station 12 and the unloading station 13. The transfer mechanism 7 can switch the position of the trays between multiple stations, thereby enabling manual batch stacking at the loading station 11, followed by the trays being placed down one by one, the retainers being picked up at the transport station 12, and then the empty trays being stacked again at the unloading station 13.

[0023] Pick-up module 2 is used to pick up the retainer from the tray on the transport station 12. Pick-up module 2 can use pneumatic or electric chuck 33 to grip and transfer the metal retainer in the width direction.

[0024] The positioning module 3 has a correction station 51 for correcting the position of the retainer picked up and placed by the picking module 2; the correction station 51 on the positioning module 3 can move and correct the position of the metal retainer in the length and width directions of the metal retainer after the metal retainer is placed, so as to reach the preset position.

[0025] The adsorption module 4 is used to pick up and transport the calibrated retainer to a preset position. The adsorption module 4 has a linear module that moves in space and an air nozzle located below the module. The air nozzle uses negative pressure to adsorb the surface of the retainer, thereby transporting and vertically inserting the metal retainer into the metal needles of the injection molded part. This ensures that each needle tip is inserted into a corresponding needle hole on the retainer, preventing excessive bending of the metal needles during subsequent transport or movement of the injection molded part, which would fail to meet production and usage requirements. The adsorption module 4 is movable in space and adsorbs the metal retainer at a designated position using negative pressure. The suction nozzle 41 of the adsorption module 4 is provided with clearance holes to avoid the top of the metal needle colliding with the top of the suction nozzle 41 after insertion.

[0026] The positioning retainer 5 has a correction station 51 for correcting the position of the injection molded part. When the positioning retainer 5 is placed on the correction station 51, it is fixed in position by abutting against the four sides inside the correction fixture. The bottom of the positioning retainer 5 is connected by a linear module and can move in the linear and vertical directions.

[0027] The comb-tooth guiding mechanism 6 includes a comb-tooth limiting groove 63. The positioning retainer 5 carries the injection molded part, guiding the metal needles through the comb-tooth limiting groove 63 and arranging them. The retainer is then inserted into the metal needles by the pickup mechanism. The comb-tooth guiding mechanism 6 is a fixed-position mechanism. The positioning retainer 5 moves vertically, first inserting the metal needles on the injection molded part into the comb-tooth limiting groove 63 from the bent portion of the needle. Then, it moves vertically again, gradually lowering the bent portion of the metal needle. The top end is straightened under the guidance of the comb teeth. Then, the suction module 4 at the top drives the retainer to move vertically, inserting the retainer into the guided and positioned metal needle. This allows for the installation of various metal retainers on the ends of the metal needles in the combed injection molded part, achieving continuous supply and unloading of retainers without frequent manual intervention or equipment adjustments. Compared to existing technologies that require complex line-changing operations for different retainers, the feeding structure of this invention greatly simplifies the feeding process and significantly improves operational convenience and production continuity. The positioning retainer 5 corrects the position of the injection-molded part, and the comb-tooth guiding mechanism 6 guides the matrix-arranged metal needles through the comb-tooth limiting grooves 63, ensuring that the metal needles maintain a neat posture before the retainer is inserted. This structure effectively avoids assembly damage or poor contact caused by misaligned metal needles, ensuring the stability and reliability of subsequent circuit connections.

[0028] Preferably, the positioning module 3 includes a first clamping module 31 and a second clamping module 32. The first clamping module 31 and the second clamping module 32 can respectively abut against the retainer from two intersecting directions. The first clamping module 31 and the second clamping module 32 each include two relatively movable clamps 33. The clamps 33 are slidably connected to the bottom of the fixed plate 34 via a slide rail, and the clamps 33 are connected to the moving end of the driving component. The clamps 33 of the first clamping module 31 and the second clamping module 32 are slidably connected to the bottom of the connecting plate 62, which can be a sliding method of slide rail and slide groove cooperation. The driving component is an electric telescopic rod or a pneumatic telescopic rod, which drives the movement of the first clamping module 31 and the second clamping module 32, which move synchronously from both sides of the retainer, respectively, so as to realize the position correction of the retainer on the plane in the width and length directions.

[0029] Preferably, the transfer mechanism 7 includes limiting plates 72 located inside the upright plates 71 on both sides of the loading station 11. The limiting plates 72 are connected to the moving end of the driving component and are used to control the bottom of the loading station 11 to lower the limiting plates 72 one by one. The limiting plates 72 are two vertically arranged metal plates. Multiple sets of trays can be manually stacked inside the limiting plates 72. Each tray has multiple slots for placing retainers. The driving component is horizontally set outside the limiting plates 72, and its moving end can extend and retract between the limiting plates 72 to support and release the trays. In addition, the bottom of the transfer mechanism 7 in this embodiment can also be provided with a lifting tray. The lifting tray can be driven by a cylinder or an electric telescopic rod. When the trays are released one by one inside the top limiting plates 72, the bottom lifting tray rises first, then moves the bottommost tray a distance, and then the moving end of the driving component extends again to the inside of the upright plate 71 to abut against the top tray and all the trays above it.

[0030] The transfer mechanism 7 also includes a transport component 73 located at the bottom of the loading station 11, the handling station 12, and the unloading station 13. Support rails 74 are also provided at the bottom of the handling station 12 and the unloading station 13. The transport component 73 includes a linear module and a vertical push-pull member connected to the linear module. The vertical push-pull member has a hook 75, which is vertically movable and used to hook onto the bottom edge of the tray. The vertical push-pull member is movable in the vertical direction. During operation, the vertical push-pull member is raised in height by the drive of the bottom telescopic member, and then the hook 75 hooks onto the bottom edge of the tray. The tray then moves in a linear direction along both sides of the support rails 74, transferring between the handling station 12 and the unloading station 13.

[0031] The transfer mechanism 7 also includes a pusher 76 located at the bottom of the unloading station 13 for attaching a pusher that rises from the bottom upwards. The inner side of the upright plates 71 on both sides of the loading station 11 is also provided with a one-way limiting block 77. One side of the one-way limiting block 77 extends into the loading station 11, and the other side extends out and is rotatably connected to the outer side of the upright plates 71 on both sides of the unloading station 13. One end of the one-way limiting block 77 extends into the inner side of the upright plate 71, while the other end is rotatably connected to the outer side of the upright plate 71. The one-way limiting block 77 can be rotatably connected to the inside of the upright plate 71 and can rotate a certain angle toward the inner top of the upright plate 71. Then, after the material tray passes the top of the one-way limiting block 77, the bottom sides of the lowered material tray press down on the top of the one-way limiting block 77, and the one-way limiting block 77 rotates to a horizontal support state for the material tray, realizing the automatic recycling of the material tray. The above-mentioned driving components are controlled by a PLC controller. During the transfer process, the material tray always maintains horizontal movement through the support slide rail 74, and the positioning of the material tray between each station is ensured by mechanical structures such as the limiting plate 72 and the one-way limiting block 77, avoiding material tray offset caused by manual handling or non-standard fixtures. Stable material supply creates the preconditions for the high-precision positioning of the cage and metal needles by the picking module 2, positioning module 3, and comb tooth guiding mechanism 6, indirectly ensuring the regularity of the metal needle posture and the reliability of the circuit connection.

[0032] In one embodiment, the comb tooth guiding mechanism 6 includes a base 61 and a connecting plate 62, the connecting plate 62 being connected to the base 61. A comb tooth limiting groove 63 is formed on the top of the connecting plate 62, and the comb tooth limiting groove 63 includes a first comb tooth groove 64 and a second comb tooth groove 65. The first comb tooth groove 64 is a strip-shaped groove in the depth direction, and the second comb tooth groove 65 is a groove formed on the top of the connecting plate 62 and intersecting with the first comb tooth. The first comb tooth groove 64 is formed in the height direction of the connecting plate 62, and the second comb tooth groove 65 is formed on the top of the connecting plate 62 and intersects with the first comb tooth groove 64. The first comb tooth groove 64 is used to limit the horizontal movement of the vertical segment of the metal needle. The vertical segment of the metal needle has limiting protrusions on both sides of its top. When the vertical segment of the metal needle is inserted into the first comb tooth, the limiting protrusions overlap within the second comb tooth groove 65, which restricts vertical movement in the horizontal plane. After being bent by the aforementioned mechanism, the metal needle forms an L-shape. Carried by the injection-molded part, the metal needle is driven by the positioning retainer 5 to move laterally to the top of the first comb groove 64, and then vertically inserted. The bent part of the metal needle will first be inserted into the interior of the first comb groove 64. The metal needle is first vertically guided and straightened. Then, the end of the metal needle forms a protrusion extending along the direction of the second comb groove 65. The protrusion in the direction of the second comb groove 65 is straightened again, thereby correcting the metal needle in two directions on the plane. Through this assembly method, metal needles with various degrees of bending can be straightened in two directions one after another. Complex correction operations of metal needles can be achieved through a simple and stable mechanism without the need for manual intervention in multiple correction and retainer assembly relationships. In addition, during the entire process of vertical insertion of the retainer, the posture of the metal needle is supported by the first comb groove 64 and the second comb groove 65, which can accurately maintain the precise insertion of the retainer and accurately solve the posture problem of the metal needle to be fixed.

[0033] In one embodiment, the top of the connecting plate 62 is provided with a first guide surface 66 on each side of the first comb groove 64, and the first guide surface 66 is distributed in a V-shape on both sides of the first comb groove 64.

[0034] The top of the connecting plate 62 also includes a second comb groove 65, on which second guide surfaces 67 are formed respectively. The second guide surfaces 67 are distributed in a V-shape on both sides of the second comb groove 65. The first guide surface 66 and the second guide surface 67 are two sets of inclined surfaces, forming inverted trapezoids. When the metal needle is vertically inserted, the first guide surface 66 and the second guide surface 67 guide the metal needle to move within a small range in two directions, preventing excessive speed and large misalignment between the metal needle and the comb groove, which could directly lead to needle breakage. This provides a high degree of positional calibration, assisting in the positional correspondence between the metal needle and the retainer.

[0035] Preferably, the metal needle further includes a bent section sequentially connected to the vertical section, the bent section having an angle with the vertical section. The bent section is a non-vertical section, the bottom of which is first inserted downwards into the first comb tooth groove 64, and then the remaining comb tooth grooves... The straightening station 51 includes multiple blocking surfaces 52, which are used to prevent the injection molded part from moving horizontally from all sides. The bottom of the positioning holder 5 is also connected to a moving module 53. The moving module 53 is used to drive the injection molded part to first move horizontally to the top of the comb tooth limiting groove 63, and then move vertically to drive the bent section of the metal needle to insert along the depth direction of the first comb tooth groove 64 until the limiting protrusion is inserted into the second comb tooth groove 65. The moving module 53 includes an X-direction linear module, a Y-direction linear module, and a Z-direction linear module. The X-direction linear module includes a fixed part and a moving part. The fixed part is a linear slide rail, and the moving part is a connecting plate that can move linearly along the slide rail. The bottom of the slide rail of the Y-direction linear module is fixed to the connecting plate, and the slide rail of the Z-direction linear module is connected to the connecting plate. The connecting plate of the Z-direction linear module is connected to the bottom of the straightening fixture. A movable straightening fixture is provided, which can accurately insert the metal needle of the injection molded part into the comb guide mechanism 6, so that the metal needle is accurately positioned and the end extends accurately towards the top, avoiding the difficulty in controlling the orientation of the metal needle.

[0036] Preferably, the correction fixture includes: Support base 511, which is a metal plate, is detachably connected to the movable module 53 by bolts.

[0037] The top of the support base 511 is connected to a backing body 512, which is used to abut against the side of the injection molded part away from the metal needle; wherein the backing body 512 is a part located at the rear of the top of the support base 511, and the side wall of the injection molded part can abut against the side wall of the backing body 512.

[0038] The top of the support base 511 has blocking portions 513 formed on both sides of the backrest 512. These blocking portions 513 respectively block the movement of the injection molded part from both sides. Each blocking portion 513 also has a strip-shaped blocking portion 514 that matches the bottom strip groove of the injection molded part. The strip-shaped blocking portion 514 prevents the injection molded part from moving away from the backrest 512. The blocking portions are C-shaped, with one end of the C-shape inserted into the bottom gap of the injection molded part and the other end abutting against both sides of the injection molded part, thereby completely fixing and positioning the injection molded part in the horizontal direction.

[0039] Preferably, the straightening fixture further includes: A connecting seat 54 is connected to the bottom of the support base 511. The support base 511 is detachably connected to the connecting seat 54. The vertical plate of the connecting seat 54 and the support base 511 are slidably connected. The horizontal plate of the connecting seat 54 is slidably connected to the support frame. A first driving member is also connected to the connecting seat 54. The first driving member is used to drive the connecting seat 54 to slide relative to the vertical plate of the support base 511. A second driving member is slidably connected between the horizontal surface of the connecting seat 54 and the support frame. The second driving member is used to drive the horizontal plate of the connecting seat 54 to move relative to the support frame. In one embodiment, in order to achieve movement in the spatial height direction and the horizontal lateral direction, the straightening fixture can be equipped with a linear drive module for position adjustment in only two directions. Only after the position of the injection molded part on the straightening fixture is corrected, it moves directly horizontally to the top of the comb tooth limiting groove 63, and then moves vertically downward, completing the function of guiding the metal needles on the injection molded part through the comb tooth guiding mechanism 6 and correcting the posture of the metal needles.

[0040] In one embodiment, the bottom of the connecting seat 54 is slidably connected to the top of the sliding base plate 8. Sliding rods 81 are slidably connected to both ends of the sliding base plate 8 in the thickness direction. The bottom of the sliding rods 81 is connected to a length extension member 82 via a connecting rod, and the top of the sliding rods 81 is connected to a pressing rod 83. The length extension member 82 drives the pressing rod 83 to press down on the top of the injection molded part, thereby fixing the position of the injection molded part on the straightening station 51 from the height direction. The plurality of blocking surfaces 52 are formed by the blocking part 513 and the support body 512. The sliding connection of the sliding rod 81 to the bottom of the connecting seat 54 allows the pressing rod 83 to come down from the top and press onto the injection molded part when it is placed on the straightening station 51, preventing the injection molded part from falling off in the height direction and providing assistance for the precise insertion of the metal needle into the through hole of the retainer.
