[0030] The technical solution protected by the utility model is described in detail below with reference to the accompanying drawings.

[0031] like Figure 1 As shown, a PIN pin 4 has a pin head 41, a pin middle part 42 and a pin tail 43 which are integrally formed and arranged in sequence. The connection between the pin head 41 and the pin middle part 42 and the connection between the pin middle part 42 and the pin tail 43 are both bent, so that when the pin middle part 42 is arranged horizontally, the pin head 41 and the pin tail 43 connected at both ends are both arranged upright. A positioning hole 44 is provided on the pin middle part 42 of the PIN pin 4.

[0032] like Figure 1-2 As shown, the present application provides a PIN needle feeding device for feeding the above-mentioned PIN needle 4. The present application specifically comprises: a placing mechanism 1 for placing PIN needle raw materials, a receiving mechanism 3 for receiving PIN needles, and a transporting mechanism 2 for transporting PIN needles from the placing mechanism 1 to the receiving mechanism 3.

[0033] like Figure 1-4 As shown, the placement mechanism 1 includes a placement fixture 11, and the placement fixture 11 has a plurality of placement parts for placing PIN pins. Among them, one side of the placement part has a placement slot 111 extending downward, and the other side has a limit interval 112. The placement slot 111 is used to accommodate the pin tail 43, and the limit interval 112 is used to limit the end of the pin middle part 42 away from the pin tail 43. The placement slot 111 is provided with a positioning hole 113 on one side close to the limit interval. When the pin tail 43 of the PIN pin is correspondingly inserted into the placement slot 111, and one end of the pin middle part 42 is located in the limit interval 112, the pin middle part 42 of the PIN pin is correspondingly placed on the upper end surface of the placement part, the positioning hole 44 of the pin middle part 42 corresponds to the positioning hole 113, and the pin head 41 of the PIN pin is correspondingly arranged upright above the placement part. Preferably, in the present embodiment, each set of placement parts is provided with two sets of symmetrical placement slots 111 and positioning holes 113, and a partition is provided in the middle of the limit interval 112. The partition divides the limit interval into two sub-limit intervals, so that two sets of PIN pins can be placed on a single placement part to increase the number of PIN pins placed on the placement fixture and improve the utilization rate.

[0034] like Figure 1-4 As shown, preferably, in this embodiment, the placement mechanism 1 is provided with two groups of the above-mentioned placement jigs 11 and a reversing assembly 12 that drives the placement jigs 11 to alternate with each other. The reversing assembly 12 includes a first slide rail group and a second slide rail group, the first slide rail group includes two mutually parallel first slide rails 121, the second slide rail group is parallelly arranged between the two first slide rails 121, and the second slide rail group includes two mutually parallel second slide rails 122. One group of the placement jigs 11 is placed on the first bracket 123, and the first bracket 123 is slidably arranged on the first slide rail 121 through a slider, and the other group of the placement jigs 11 is slidably arranged on the second slide rail 122 through a slider. The support of the first bracket 123 allows a height difference between the two groups of placement jigs 11, and when the two groups of placement jigs 11 slide toward each other along the slide rails until they are intertwined, they will not interfere with each other.

[0035] like Figure 1-4 As shown, the two sets of placement jigs 11 are connected to the reversing drive 124, and the reversing drive 124 includes a driving wheel, a driven wheel, a belt and a rotating motor, wherein the driving wheel and the driven wheel are respectively placed at both ends of the slide rail and are connected in series through a belt, and the driving wheel is connected to the output end of the rotating motor, and the driving wheel is driven to rotate by the action of the rotating motor, thereby driving the pulley to rotate. (The structure of the reversing drive belongs to the conventional technical structure in the industry, so it is not specifically indicated in the figure). The two sets of placement jigs 11 are respectively connected to the upper and lower layers of the belt, so that when the belt rotates in a certain direction, the two sets of placement jigs 11 slide toward each other, staggered at the middle position of the belt, and then slide back and forth. The reversing component 12 is used to realize the two sets of placement jigs 11 to alternately perform manual placement and mechanical grabbing actions, effectively improving work efficiency and reducing working time.

[0036] like Figure 2-5 As shown, the transport mechanism 2 includes a mechanical arm 21, and a connector 22 is disposed at the end of the mechanical arm 21. The connector 22 is provided with a clamping assembly 23 for clamping the PIN needle.

[0037] like Figure 1-5 As shown, the clamping assembly 23 includes a pneumatic clamp 231 disposed on the connector 22, and the pneumatic clamp 231 clamps the pin head 41 of the PIN pin and drives the PIN pin to move. A support plate 236 is provided on one side of the pneumatic clamp 231, and an auxiliary positioning column 237 is provided on the end surface of the support plate 236 away from the connector 22. When the pneumatic clamp 231 clamps the PIN pin located on the placement fixture 11, the auxiliary positioning column 237 can pass through the positioning hole 44 of the PIN pin 4 and be inserted into the positioning socket 113 of the placement fixture 11 to ensure that the pneumatic clamp 231 can accurately clamp the pin head 41 of the PIN pin.

[0038] like Figure 1-5As shown, preferably, an auxiliary pusher is arranged on the side of the clamping assembly 23, and the auxiliary pusher includes a pusher cylinder 232 arranged on the connector 22, and a connecting plate 233 is arranged at the output end of the pusher cylinder 232, and a pusher plate 234 and a pusher rod 235 are arranged on the end surface of the connecting plate 233 away from the connector 22. In this embodiment, the pusher plate 234 is correspondingly placed between the pneumatic clamp 231 and the auxiliary positioning column 237, so that the pusher plate 234 acts on the middle part 42 of the pin. When the pushing action is performed, the pusher rod of the pusher cylinder 232 extends, driving the pusher plate 234 to push the middle part 42 of the pin of the PIN, pushing the PIN out and separating from the auxiliary positioning column 237. The pusher plate 234 and the pusher rod 235 act simultaneously to improve the stability of the PIN during the pushing process.

[0039] like Figure 6-7 As shown, the material receiving mechanism 3 includes a vertical material receiving plate 31, and a detachable material loading fixture 33 is arranged on one side of the material receiving plate 31. In this embodiment, a horizontally protruding support column 32 is arranged on the side end surface of the material receiving plate 31, and a mounting hole 331 is correspondingly opened on the material loading fixture 33. When the mounting hole 331 of the material loading fixture 33 is correspondingly sleeved on the support column 32, the material loading fixture 33 is correspondingly arranged on the material receiving plate 31 to receive the PIN needle. In this embodiment, a telescopic cylinder 34 is provided on the side of the material receiving plate 31 away from the support column 32, and the output end of the telescopic cylinder 34 is toward the side of the material receiving plate 31 and is connected to a pushing piece (not marked), and an action port is opened at the position of the pushing piece corresponding to the material receiving plate 31. The action of the telescopic cylinder 34 drives the pushing piece to extend through the action port and act on the material carrier 33, moving the material carrier 33 in a direction away from the side of the material receiving plate 31, so that the material carrier 33 is separated from the material receiving plate, and the material carrier 33 is replaced.

[0040] Specifically, Figure 7 As shown, the material loading jig 33 has a material receiving slot 332 which is opened obliquely to accommodate the tail of the PIN pin. A pressing fitting 333 is obliquely provided on an inner side wall of the material receiving slot 332 to fix the position of the PIN pin. The pressing fitting 333 includes a first elastic member and a ball head arranged at the end of the first elastic member. The first elastic member is built into the material loading jig 33. When the first elastic member is not subjected to external force, the ball head is partially placed in the material receiving slot 332. When the tail of the pin is inserted into the material receiving slot 332, the ball head is pushed by the external force and retreats to the side wall of the material receiving slot 332. The first elastic member is in a compressed state, exerting an outward force on the ball head, so that the ball head and the tail of the pin in the material receiving slot 332 abut against each other.

[0041] like Figure 5-7As shown, a positioning fitting 334 is also provided on the end face of the material carrier 33 away from the material receiving vertical plate 31. The positioning fitting 334 includes a second elastic member and a positioning column. The second elastic member is built into the material carrier 33. When the second elastic member is not subjected to external force, the positioning column protrudes from the side end face of the material carrier 33. When the conveying mechanism inserts the PIN needle into the material carrier, the auxiliary positioning column 237 on the clamping assembly 23 abuts against the positioning column, the second elastic member is compressed, and the positioning column retreats toward the inside of the material carrier.

[0042] In this embodiment, the first elastic member and the second elastic member are both built into the material loading fixture, and are not shown in the drawings. In a specific embodiment, the first elastic member and the second elastic member can be springs.

[0043] Working principle:

[0044] The PIN needles 4 are manually inserted into the placement slots 111 of the placement jig 11 in sequence. After all the placement parts on the placement jig 11 are loaded with PIN needles, the reversing assembly 12 reverses the placement jig 11 and transfers it to the side close to the conveying mechanism 2, and the conveying mechanism 2 unloads the PIN needles.

[0045] The clamping assembly 23 is placed above the placement portion, and the clamping assembly 23 moves downward. The auxiliary positioning column 237 passes through the positioning hole 44 of the PIN needle and is inserted into the positioning socket 113. The push plate 234 abuts against the upper end surface of the placement portion. The pneumatic clamp 231 clamps the pin head 41 of the PIN needle. The mechanical arm 21 drives the clamping assembly 23 to rise and takes the PIN needle out of the placement slot 111.

[0046] Before the conveying mechanism 2 conveys the PIN needle to the material loading jig 33, the pin tail of the PIN needle is inserted into the material receiving slot 332 accordingly, and then the auxiliary positioning column 237 of the clamping component 23 corresponds to the positioning column of the positioning fitting 334, and the positioning column is pressed into the material loading jig 33, and the end part of the auxiliary positioning column 237 enters the material loading jig 33, and then the pushing cylinder 232 is actuated to push the PIN needle toward the material loading jig 33, and push the PIN needle against the side wall of the material loading jig 33, and then the clamping component 23 retreats and the pushing cylinder 232 always applies a pushing force to the PIN needle to ensure that the PIN needle will not be displaced due to friction during the process of the auxiliary positioning column 237 withdrawing from the PIN needle positioning hole 44, thereby completing the action of inserting the PIN needle into the material loading jig 33.

[0047] The above description is only an embodiment of the present invention, and does not limit the patent scope of the present invention. Any equivalent structure or equivalent process transformation made by using the contents of the specification and drawings of the present invention, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present invention.
