DETAILED DESCRIPTION
[0030] The embodiments of the present application will be described in detail with specific examples. The skilled in the art can easily understand other advantages and functions of the present application from the content disclosed in the specification. The present application can also be implemented or applied in other different embodiments, and the details in the specification can be modified or changed based on different views and applications without departing from the spirit of the present application. It should be noted that the following examples and features in the examples can be combined with each other without conflict.
[0031] It should be noted that the diagrams provided in the following examples only schematically illustrate the basic concept of the present application, and only show the components related to the present application in the diagrams, not the number, shape and size of the components when actually implemented. The shape, number and proportion of each component when actually implemented can be arbitrarily changed, and the component layout pattern can also be more complex.
[0032] Figure 1 The structure of the clamp in the related art is shown. As shown in Figure 1 In the application process of the manufacturing process, the clamp in the related art generally uses two clamping jaws to alternately clamp the clamped member (the clamped member in the present embodiment and the related art is a Pin line, and hereinafter the Pin line is used to represent a clamped member, in addition, the clamped member can also be another linear structure), thereby reducing the waste of Pin production rhythm. Each clamping jaw is divided into upper and lower clamps for cooperation.
[0033] The working process of the clamp in the related art is as follows:
[0034] 1) In the production process, a cutter cuts off a Pin line; 2) the clamping jaw at the current Pin connecting position clamps the Pin line; 3) the clamping jaw moves downward by a distance of the thickness of a Pin line; 4) whether the feeding of the current line slot is finished? If not, continue to feed the next Pin, repeat the processes of 1) to 3); 5) if the feeding of the current line slot is finished, the current Pin connecting clamping jaw is closed, and moves out of the current Pin connecting position; 6) the line slot is fed into a specified carrier; 7) the clamping jaw on the other side enters the Pin connecting position to become the current clamping jaw; 8) the line feeding machine continues to feed the next Pin line, and repeats the operations of 1) to 6).
[0035] The inventor has found that the clamping jaw in the prior art has the following advantages and disadvantages. Advantages: 1) simple structure, high realization; 2) low technical requirements, simple manufacturing. Disadvantages: the clamping jaw uses the concept of alternating Pin connection, and each time the clamping jaw is replaced, the production cycle of the Pin is wasted. Specifically, each time the clamping jaw is replaced, the wasted time is as follows: 1) the cylinder action time of the clamping jaw closing: 0.3s; 2) the waiting time of the clamping jaw moving down out of the Pin connection position: 0.1s; 3) the waiting time of the new clamping jaw entering the Pin connection position: 0.1s. That is: each time the clamping jaw is replaced, the production cycle will wait: 0.3+0.1+0.1=0.5(s). If there are 6 Pin lines in a slot Pin line, the wasted Pin production cycle is: 0.083s, that is, for a product of 48 slots, the wasted production cycle is: 0.083*48=3.98(s)
[0036] Figure 2 The structure diagram of the clamp 100 is provided for the embodiment of the utility model. As shown in Figure 2 The utility model provides a kind of clamp 100, and the clamp 100 includes first clamping jaw unit 11 and second clamping jaw unit 12.First clamping jaw unit 11 includes first main body clamping jaw 111 and auxiliary clamping jaw 112, auxiliary clamping jaw 112 is cooperated to form temporary storage chamber 113 itself;Second clamping jaw unit 12 at least includes second main body clamping jaw 121;Wherein, first main body clamping jaw 111 and second main body clamping jaw 121 can be mutually matched, to form accommodating chamber 122, temporary storage chamber 113 and accommodating chamber 122 are used to place clamped piece 300;Auxiliary clamping jaw 112 is set in dislocation with first main body clamping jaw 111, to make temporary storage chamber 113 and accommodating chamber 122 mutually dislocate.
[0037] It is worth mentioning that the clamp 100 has the accommodating chamber 122 for placing the clamped piece 300, and also has the auxiliary clamping jaw 112 to form the temporary storage chamber 113 for temporarily storing the clamped piece 300;At the same time, the accommodating chamber 122 and the temporary storage chamber 113 are mutually dislocated, so that the clamped piece 300 can be alternately stored, and the mutual interference between the accommodating chamber 122 and the temporary storage chamber 113 is avoided, thereby achieving the technical effects of saving production cycle and improving production efficiency.
[0038] Please refer to Figure 3 , Figure 3 First clamping jaw unit 11 in the first clamping jaw unit 11 is another embodiment in the embodiment. First clamping jaw unit 11 also includes connecting plate 114, and first main body clamping jaw 111 and auxiliary clamping jaw 112 are installed on connecting plate 114, and first main body clamping jaw 111 and auxiliary clamping jaw 112 are set in dislocation along the length direction of connecting plate 114 and the width direction of connecting plate 114.
[0039] It is worth noting that by arranging the first main jaw 111 and the auxiliary jaw 112 in the length direction and the width direction of the connecting plate 114, the mutual interference between the accommodation chamber 122 and the temporary storage chamber 113 can be effectively avoided, ensuring that the clamp 100 works more smoothly and unobstructed during alternating work, thereby improving the overall work efficiency. Specifically, as shown in Figure 4 , the mutual misalignment of the auxiliary jaw 112 and the first main jaw 111 in the length direction of the connecting plate 114 can prevent the first main jaw 111 of the second set of clamps 100 from colliding with the auxiliary jaw 112 of the first set of clamps 100 in the length direction, and the mutual misalignment can allow the first main jaw 111 of the second set of clamps 100 to smoothly take over the Pin line on the auxiliary jaw 112 of the first set of clamps 100, improving production stability. In addition, as shown in Figure 3 , the mutual misalignment of the auxiliary jaw 112 and the first main jaw 111 in the width direction of the connecting plate 114 can prevent the auxiliary jaw 112 and the first main jaw 111 in the same set of clamps 100 from interfering with each other during wiring, thereby ensuring the stability of the wiring. It can also be understood that the length direction refers to the direction of the longer section of the connecting plate 114 as shown in Figure 3 , and the width direction refers to the direction of the shorter section of the connecting plate 114 as shown in Figure 3 .
[0040] In this embodiment, the auxiliary jaw 112 is detachably connected to the connecting plate 114.
[0041] It is worth noting that this structure can allow the auxiliary jaw 112 to be quickly replaced when it is damaged or worn, reducing maintenance time. In addition, users can replace auxiliary jaws 112 of different specifications or shapes according to different work requirements to meet the wiring needs of various Pin line operations, improving the versatility and flexibility of the equipment. In addition, this structure allows the clamp 100 to only add the auxiliary jaw 112 based on the original structure to solve the problem of temporarily storing Pin lines, which has low modification cost and is conducive to industrial promotion.
[0042] Please refer again to Figure 3 , the auxiliary jaw 112 includes a support portion 1121, an extension portion 1122, and a clamping portion 1123. The support portion 1121 is detachably connected to the connecting plate 114 by bolts. One end of the extension portion 1122 is connected to the side of the support portion 1121 away from the connecting plate 114. The other end of the extension portion 1122 is connected to the clamping portion 1123. The clamping portion 1123 has a groove, and the groove itself forms a temporary storage chamber 113.
[0043] It is worth noting that the extension part 1122 connects the support part 1121 and the clamping part 1123, making the structure of the first clamping jaw unit 11 more compact. The groove provided on the clamping part 1123 can effectively form a temporary storage chamber 113, realizing the function of temporarily storing the Pin line. As shown in Figure 3 the embodiment, the support part 1121 is a large square block structure, the extension part 1122 is a long strip structure with a cross section smaller than that of the support part 1121, and the clamping part 1123 is a bent structure with a groove. It can be understood that the larger support part 1121 can provide better stability, while the extension part 1122 and the clamping part 1123 only need to function to clamp the Pin line. As shown in the structure, the clamping effect can be ensured while reducing production costs.
[0044] It is also worth noting that the auxiliary clamping jaw 112 in the embodiment is two, arranged on both sides of the connecting plate 114. According to different specific implementation environments, the auxiliary clamping jaw 112 can also be one, three, four, etc. The embodiment does not constitute a limitation on the specific number of auxiliary clamping jaws 112.
[0045] Please refer again to Figure 3 , the extension part 1122 has a weight-reducing hole 1124. It is worth noting that by providing the weight-reducing hole 1124 on the extension part 1122, the overall weight of the auxiliary clamping jaw 112 can be significantly reduced, thereby reducing the total weight of the clamp 100, making the clamp 100 more responsive when moving quickly or operating frequently, and improving the wiring efficiency of the equipment.
[0046] In the embodiment, the first main body clamping jaw 111 includes a first planar section 1111, a first bent section 1112, and a baffle part 1113, the baffle part 1113 is arranged on the first planar section 1111, and the first bent section 1112 is connected with the free end of the first planar section 1111; the second main body clamping jaw 121 includes a second planar section 1211 and a second bent section 1212, the second bent section 1212 is connected with the free end of the second planar section 1211; wherein through the cooperation of the first planar section 1111, the first bent section 1112, the baffle part 1113, the second planar section 1211 and the second bent section 1212, a receiving chamber 122 for limiting the degrees of freedom of the clamped part 300 in multiple directions can be formed.
[0047] It is worth noting that through the cooperation of the first planar section 1111, the first bent section 1112, the baffle part 1113, the second planar section 1211 and the second bent section 1212, a receiving chamber 122 can be effectively formed, which can limit the degrees of freedom of the Pin line in multiple directions, ensure the stability of the Pin line during clamping, and prevent unnecessary movement or rotation of the Pin line during operation.
[0048] Optionally, the first bending section 1112 is arranged to bend towards the second bending section 1212, and the second bending section 1212 is arranged to bend towards the first bending section 1112; when the first main body clamp jaw 111 and the second main body clamp jaw 121 are mutually matched, the baffle part 1113 abuts against the second planar section 1211.
[0049] Specifically, the structure arrangement can make the first main body clamp jaw 111 and the second main body clamp jaw 121 more stable after being matched, reduce the occurrence of gaps, and further avoid the Pin line from falling off or deviating.
[0050] In the embodiment, the accommodation space of the temporary storage chamber 113 is smaller than the accommodation space of the containing chamber 122. It can be understood that the temporary storage chamber 113 in the embodiment can temporarily store 3 Pin lines, and the containing chamber 122 can store 10 Pin lines, which can avoid the situation that the temporary storage chamber 113 temporarily stores too many Pin lines and the containing chamber 122 cannot accommodate, and further ensure the work efficiency of the line transmission.
[0051] The embodiment further discloses a clamping assembly, which comprises the above-described clamp 100, and the number of the clamp 100 is two groups, and the two groups of clamp 100 are arranged on both sides to alternately clamp the clamped member 300.
[0052] The embodiment further discloses a material receiving system 200, which comprises the above-described clamping assembly. The material receiving system 200 further comprises a cutter (not shown in the figure), a line feeding machine (not shown in the figure), a carrier (not shown in the figure) and the like.
[0053] The working flow of the pin receiving system 200 is as follows: 1) during production, a cutter cuts off a pin; 2) a pin receiving clamp 100 at a current pin receiving position receives the pin; 3) the pin receiving clamp 100 moves downward by a thickness of the pin; 4) whether the feeding of the current wire slot (i.e. the accommodation chamber 122) is finished? If not, the next pin is fed, and the processes of 1) to 3) are repeated; 5) if the feeding of the current wire slot is finished, the current pin receiving clamp 100 is closed and moves downward by 10 mm until the auxiliary clamp jaw 112 reaches the pin receiving position; 6) the cutter continues to cut off a pin; 7) the auxiliary clamp jaw 112 receives the pin, and if there are not two pins on the auxiliary clamp jaw 112, the processes of 6) and 7) are repeated; 8) if there are two pins on the auxiliary clamp jaw 112, another set of clamp jaws enters and normally reaches the position of receiving the third pin, and the two pins on the auxiliary clamp jaw 112 are contained in the position; 9) the cutter continues to cut off a pin, the auxiliary clamp jaw 112 moves downward, and all the pins on the auxiliary clamp jaw 112 are placed on another set of clamp jaws 100, and meanwhile, another set of clamp jaws 100 receives the third pin; 10) the auxiliary clamp jaw 112 continues to move downward and exits the pin receiving area of the clamp jaws, and the pins clamped by the auxiliary clamp jaw 112 are placed into a carrier; 11) the feeding machine continues to feed the next pin, and the processes of 1) to 10) are repeated.
[0054] In summary, the pin receiving system 200 can use the auxiliary clamp jaw 112 to synchronously receive the pins, so that the waiting time is fully utilized, and the production rhythm of receiving the pins is avoided. That is, by only adding the simple auxiliary clamp jaw 112, the effect of saving 0.3 seconds per slot of receiving the pins is achieved, the production line cost is not increased, and the production rhythm of the production line is improved. It can be understood that the pin receiving system 200 can be used not only for receiving the pin, but also for automatically receiving other wire harnesses.
