DETAILED DESCRIPTION

[0029] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present application can be combined with each other. Now, in conjunction with the accompanying drawings, a preferred embodiment of the present utility model is described in detail.

[0030] like Figures 1 to 4As shown, the embodiment of the utility model provides a pin forming device 100, comprising: a base 110, and a feeding assembly 120 and a stand 130 arranged on the base 110, the stand 130 is provided with a pin positioning assembly 140, a pin bending assembly 150 and a pin shearing assembly 160; the feeding assembly 120 comprises a feeding module 122, and a product positioning assembly 124 arranged on the feeding module 122, wherein the product positioning assembly 124 comprises a support plate 1241, and a placement block 1242, a positioning block 1243 and a pressing block arranged on the support plate 1241 Tightening module 1244; a plurality of accommodating grooves 1242a are arranged at intervals on the placing block 1242, and a notch 1243a corresponding to the accommodating groove 1242a is arranged on the positioning block 1243, so that after the product is placed in the accommodating groove 1242a, the pin can extend from the notch 1243a; the pin positioning assembly 140 includes a pressing block 141, and the pressing block 141 can cooperate with the notch 1243a to press the pin of the product to the bottom of the notch 1243a; the pin bending assembly 150 is used to form the pin, and the pin cutting assembly 160 is used to cut off the end of the formed pin.

[0031] Specifically, the pin forming device provided in the embodiment of the present application is suitable for a structural form with two or three pins arranged side by side. When in use, it is necessary to first place the corresponding product (such as an electronic device such as a photodiode) at the receiving groove 1242a on the placement block 1242, and make the pin extend from the notch 1243a. In actual applications, the cross-section of the receiving groove 1242a can be set to a V shape, so that products of different sizes can be placed normally. The number of notches 1243a can be set to be equal to the number of pins according to actual needs, so as to facilitate the normal extension of the pins. In addition, the notch 1243a and the receiving groove 1242a need to have a corresponding relationship not only in the horizontal position, but also in the vertical position. A specific corresponding relationship is required to ensure that the corresponding product is placed in the receiving groove 1242a. After the pin extends smoothly from the notch 1243a, and the pin corresponds to the bottom of the groove of the notch 1243a in the vertical height to avoid lateral stress.

[0032] After the product is placed in the receiving groove 1242a and extends from the notch 1243a, the main body of the product needs to be pressed and positioned by the pressing module 1244 to avoid shaking and shifting of the product during the movement of the support plate 1241, which is conducive to ensuring the reliability of the molding. After the product is positioned on the placement block 1242, the support plate 1241 is placed on the feeding module 122 to move the product to the processing and molding position. At this time, the pin positioning component 140 is actuated to press the pressing block 141 downward to cooperate with the notch 1243a, and press the pin to the bottom of the notch 1243a, so that the pin bending component 150 can bend and mold the protruding part of the pin.

[0033] The pin forming device 100 provided in the embodiment of the present application facilitates the feeding processing of the product through the feeding assembly 120 set on the base 110, and facilitates the cooperation with the feeding assembly 120 through the pin positioning assembly 140, the pin bending assembly 150 and the pin cutting assembly 160 set on the stand 130 to achieve the forming and trimming of the pin. At the same time, through the cooperation of the feeding module 122 and the product positioning assembly 124, after the product is placed on the corresponding placement block 1242 on the support plate 1241, the pin of the product can extend through the notch 1243a, and the main body of the product is positioned by the pressing module 1244 to ensure the stability of the relative position of the product relative to the placement block 1242. In addition, by setting the notch 1243a corresponding to the accommodating groove 1242a on the positioning block 1243, it is helpful to ensure that when the pin extends out of the notch 1243a, the pin is prevented from being subjected to lateral stress. During the pin forming operation, the pin positioning assembly 140 is first activated to drive the pressing block 141 to press down and cooperate with the notch 1243a, and the pin is pressed at the bottom of the notch 1243a to prevent the bending force from being transmitted to the root of the pin during the later forming process. The pin is then formed by the pin bending assembly 150, and the excess length of the pin after forming can be cut off by the pin cutting assembly 160. The above method can protect the root of the electronic device and prevent the root from tearing, thereby ensuring the stability and service life of the pin of the electronic device after forming.

[0034] like Figure 3 As shown, the feeding assembly 120 includes a slide cylinder 1222 connected to the base 110 and a placement seat 1224 connected to the slide cylinder 1222 . The placement seat 1224 is used to place a pallet 1241 so as to drive the pallet 1241 to move closer to or away from the pin positioning assembly 140 through the slide cylinder 1222 .

[0035] Specifically, in order to make full use of the space, a slot can be opened on the base 110, and the slide cylinder 1222 is set on the back of the base 110, and the placement seat 1224 is extended from the above-mentioned slot to the upper surface of the base 110, so as to place the pallet 1241 on the placement seat 1224. In this way, when the slide cylinder 1222 is hidden, it can be ensured that the placement seat 1224 drives the pallet 1241 to approach or move away from the pin positioning assembly 140, so as to switch the pallet 1241 between the processing position and the placement position. It can be understood that in the process of placing the pallet 1241 on the placement seat 1224, automatic placement can be achieved by the cooperation of a robot, or it can be carried out by manual placement, and it can be flexibly set according to the requirements of the production line.

[0036] like Figure 3As shown, there are two placement blocks 1242, which are respectively located on the opposite sides of the support plate 1241, and there are multiple accommodating grooves 1242a, which are spaced apart on the placement block 1242. A limiting clamping protrusion is provided on one of the support plate 1241 and the placement seat 1224, and a limiting groove is provided on the other so that the limiting clamping protrusion is inserted into the limiting groove.

[0037] Specifically, in order to improve the efficiency of pin forming, placement blocks 1242 can be respectively provided on opposite sides of the support plate 1241. In this way, after the product on one side of the support plate 1241 is processed, the support plate 1241 only needs to be rotated 180° to process the product on the other side. It is understandable that when rotating the support plate 1241, the support plate 1241 can be rotated manually, or a turntable can be provided on the placement seat 1224, and the support plate 1241 can be fixed on the turntable to realize the automatic rotation of the support plate 1241. In addition, a plurality of accommodating grooves 1242a are spaced apart on the placement block 1242. When processing the product on one side, multiple products can be processed at the same time, which is conducive to improving the processing and forming efficiency. At the same time, by providing a limiting protrusion on one of the pallet 1241 and the placement seat 1224 and a limiting groove on the other, the limiting protrusion can be inserted into the limiting groove. When the pallet 1241 is placed on the placement seat 1224, the pallet 1241 can be limited to ensure the position accuracy of the pallet 1241.

[0038] like Figure 3 and Figure 5 As shown, a limiting hole is provided on the placement block 1242, and the clamping module 1244 includes a connecting rod 1244a inserted in the limiting hole, and a stopper 1244b connected to one end of the connecting rod 1244a, and a first elastic member is provided on the connecting rod 1244a to provide an elastic force to move the stopper 1244b toward the placement block 1242.

[0039] Specifically, the limiting hole arranged on the placing block 1242 has a stepped groove, and a limiting cap is correspondingly arranged at the end of the connecting rod 1244a. The first elastic member can be a compression spring, which is sleeved on the connecting rod 1244a, and one end of the compression spring is abutted against the stepped groove, and the other end is abutted against the limiting cap to provide an elastic force to move the stopper 1244b toward the placing block 1242, thereby pressing the product placed in the accommodating groove 1242a.

[0040] like Figure 5 As shown, the stopper 1244b is L-shaped, the connecting rod 1244a is connected to the connection of the two right-angle arms of the stopper 1244b, and an elastic pad 1244c is provided on one of the right-angle arms.

[0041] Specifically, by setting the stopper 1244b to be L-shaped, when placing the product, it is convenient to move the stopper 1244b so that the stopper 1244b deviates from the receiving groove 1242a, which is convenient for placing the product. After placing the product in the receiving groove 1242a, the stopper 1244b can be manually pulled up, and the stopper 1244b can be rotated so that the elastic pad 1244c corresponds to the receiving groove 1242a, so as to limit the position of the product. In addition, the setting of the elastic pad 1244c is conducive to protecting the product and preventing the product from being damaged by pressure.

[0042] like Figure 6 As shown, the pin positioning assembly 140 also includes a first linear driving member 143 connected to the stand 130 and a first vertical plate 142 connected to the base 110, and a first slide rail 144 arranged on the first vertical plate 142, and a first connecting plate 145 is slidably arranged on the first slide rail 144, and the first connecting plate 145 is connected to the first linear driving member 143 to drive the first connecting plate 145 to slide relative to the first slide rail 144, and the pressure block 141 is connected to the first connecting plate 145. The pressure blocks 141 are arranged in plurality and are respectively arranged in one-to-one correspondence with the slots 1243a.

[0043] Specifically, through the first vertical plate 142 connected to the base 110, and the first slide rail 144 arranged on the first vertical plate 142, the first slide rail 144 extends along a plane perpendicular to the support plate 1241. When the first linear drive member 143 arranged on the stand 130 is actuated, it can drive the first connecting plate 145 to slide along the first slide rail 144. In order to ensure the stability during sliding, two first vertical plates 142 can be arranged on the base 110 in opposition, and a first slide rail 144 can be arranged on each first vertical plate 142, so that the opposite sides of the first connecting plate 145 are slidably connected to the first slide rail 144. It can be understood that two first linear drives 143 can also be arranged on the stand 130 to ensure the balance of force on the first connecting plate 145. Among them, the first linear drive member 143 can adopt a cylinder, a hydraulic cylinder or a linear motor to control the movement of the first connecting plate 145. In addition, the plurality of pressing blocks 141 disposed on the first connecting plate 145 are respectively disposed in one-to-one correspondence with the notches 1243 a to facilitate pressing and positioning of the pins.

[0044] like Figure 7 As shown, the pressing block 141 includes a mounting seat 1412 connected to the first connecting plate 145, and a pressing head 1413 arranged on the mounting seat 1412. The pressing head 1413 includes a base 1413a connected to the mounting seat 1412, and protrusions 1413b arranged at intervals on the base 1413a. The protrusions 1413b are used to cooperate with the slots 1243a.

[0045] Specifically, the mounting seat 1412 connected to the connecting plate facilitates the connection between the pressing block 141 and the first connecting plate 145, and improves the structural strength of the pressing block 141. The pressing head 1413 is used to align with the positioning block 1243. At the same time, the pressing head 1413 is connected to the mounting seat 1412 through the base 1413a, and the protrusions 1413b arranged on the base 1413a at intervals. When the pressing block 141 is pressed down, the protrusions 1413b can extend into the notch 1243a to achieve the compression and positioning of the pins.

[0046] like Figure 8 As shown, the pin bending assembly 150 includes a second linear drive member 151 connected to the stand 130, a second vertical plate 152 connected to the base 110, and a second slide rail 153 arranged on the second vertical plate 152, a second connecting plate 154 is slidably arranged on the second slide rail 153, and the second linear drive member 151 is connected to the second connecting plate 154, and a forming block 155 is arranged on the second connecting plate 154 to drive the forming block 155 to move closer to or away from the support plate 1241.

[0047] Specifically, through the second vertical plate 152 connected to the base 110, and the second slide rail 153 arranged on the second vertical plate 152, the second slide rail 153 extends along a plane perpendicular to the support plate 1241. When the second linear drive member 151 arranged on the stand 130 is actuated, it can drive the second connecting plate 154 to slide along the second slide rail 153. In order to ensure the stability during sliding, two second vertical plates 152 can be arranged opposite to each other on the base 110, and a second slide rail 153 can be arranged on each second vertical plate 152, so that the opposite sides of the second connecting plate 154 are slidably connected to the second slide rail 153. It can be understood that two second linear drives 151 can also be arranged on the stand 130 to ensure the balance of force on the second connecting plate 154. Among them, the second linear drive member 151 can adopt a cylinder, a hydraulic cylinder or a linear motor to control the movement of the second connecting plate 154. In addition, during the pressing process, the forming block 155 provided on the first connecting plate 145 can form the portion of the pin extending out of the positioning block 1243. When the forming block 155 is away from the support plate 1241, the support plate 1241 can be replaced or turned to perform continuous forming.

[0048] like Figure 8As shown, the pin shearing assembly 160 includes a third linear drive member 161 connected to the stand 130, and an upper cutter 162 connected to the forming block 155, a gap is formed between the forming block 155 and the second connecting plate 154, and the upper cutter 162 is located at the gap; a connecting hole is provided on the forming block 155, a limiting rod 163 is provided on the connecting hole, the upper cutter 162 is slidably connected to the limiting rod 163, and a second elastic member is provided between the upper cutter 162 and the forming block 155, so that the upper cutter 162 is recessed in the gap in the initial state, the third linear drive member 161 is connected to the upper cutter 162, and is used to drive the upper cutter 162 to protrude from the forming block 155, and a lower cutter 125 corresponding to the upper cutter 162 is also provided on the support plate 1241.

[0049] Specifically, when the second linear drive member 151 drives the forming block 155 to press down, the upper cutter 162 will move with the forming block 155. Since the upper cutter 162 is slidably connected to the limiting rod 163, and a second elastic member is provided between the upper cutter 162 and the forming block 155, when the upper cutter 162 is not subjected to the force applied by the third linear drive member 161, under the action of the second elastic member, the upper cutter 162 is recessed in the gap and will not protrude, nor will it affect the normal processing and forming of the pin. Among them, the second elastic member can be a compression spring, and the upper cutter 162 and the limiting rod 163 can be connected by ear plates protruding on both sides of the upper cutter 162, and the two ends of the compression spring are held between the ear plates and the forming block 155. The gap formed between the forming block 155 and the second connecting plate 154 can be formed by providing a groove on the forming block 155 to ensure the compactness of the mutual cooperation. After the pin is formed, the third linear drive member 161 is controlled to move, driving the upper cutter 162 to protrude from the forming block 155, and cooperate with the lower cutter 125 provided on the support plate 1241 to achieve the cutting of the end of the pin. The upper cutter 162 and the side of the lower cutter 125 cooperate with each other, and when the upper cutter 162 is pressed down, the required shear force can be formed. In addition, the third linear drive member 161 can adopt a cylinder, a hydraulic cylinder or a linear motor to control the movement of the upper cutter 162. When there is no need to control the upper cutter 162, the third linear drive member 161 is separated from the contact with the upper cutter 162, and the push rod can be used to press down when pressing down.

[0050] like Fig. 9 As shown, a first arc angle 1243b is provided on the side of the positioning block 1243 facing away from the placing block 1242, and a second arc angle corresponding to the first arc angle 1243b is provided on the forming block 155. The first arc angle 1243b is above the upper end surface of the lower cutting knife 125, and the forming block 155 can cooperate with the upper end surface of the lower cutting knife 125 to form the pin.

[0051] Specifically, through the cooperation of the first arc angle 1243b and the second arc angle, the bending shape of the pin can be made to transition more smoothly, and damage to the pin during the molding process can be avoided, which is conducive to improving the molding effect. In addition, during molding, the molding block 155 can cooperate with the upper end surface of the lower cutter 125 to bend the pin into a desired shape. With the above form, the lower cutter 125 can not only cooperate with the upper cutter 162 to achieve the shearing of the pin, but also cooperate with the molding block 155 to achieve the molding of the pin, which is conducive to improving the efficiency of mutual cooperation, reducing the use of parts, and reducing production costs.

[0052] It should be understood that the above embodiments are only used to illustrate the technical solutions of the present utility model rather than to limit it. For those skilled in the art, the technical solutions described in the above embodiments can be modified, or some of the technical features therein can be replaced by equivalents; and all these modifications and replacements should fall within the scope of protection of the claims attached to the present utility model.
