[0052] The cleaning-free workpiece clamping carrier 1000 according to an embodiment of the present invention will be described in detail below with reference to the accompanying drawings.

[0053] Reference Figures 1 to 3As shown, the cleaning-free workpiece clamping carrier 1000 provided according to the embodiment of the utility model includes a workpiece carrier plate 10 for carrying a workpiece and a cleaning-free easy-tear film (not shown);

[0054] The upper end surface of the workpiece carrier 10 is downwardly provided with a plurality of slots 101 for inserting and fixing small workpieces; the easy-tear film (not shown) is peelably adhered to the upper end surface of the workpiece carrier 10 where the slots 101 are not located.

[0055] Based on the above, it is clear that when the present application is implemented, it is mainly used as a cleaning-free workpiece clamping carrier 1000.

[0056] Specifically, when applying the present application, small workpieces that need to be assembled, such as operating buttons, cameras, and lighting lamps that constitute a smartphone, are inserted into the plurality of slots 101 at appropriate orientations and angles. Then, the whole formed by the present application can be transported to the side of the automation equipment via a material conveyor belt, etc., and picked up by a robot to be fixed to a large workpiece such as a smartphone main control board. In this way, the present application can be easily used.

[0057] The use of the above-mentioned application will obviously have the following technical effects:

[0058] When glue and / or oily substances drip onto the upper end surface of the workpiece carrier 10 described in the present application, the easy-tear film (not shown) can be torn off regularly or irregularly, and a new easy-tear film (not shown) can be replaced to stick it to the upper end surface of the workpiece carrier 10 described in the present application, so as to continue to use the present application. In this way, it is unnecessary to wipe and clean the upper end surface of the workpiece carrier 10 described in the present application, which saves time and effort in operation, and can greatly reduce the workload and labor costs of operators. In addition, the easy-tear film (not shown) used is obviously made of a thin film material, and its use cost is low, and the relative labor cost is negligible, so that the use cost of the present application is also low.

[0059] Furthermore, through the above-mentioned optimized design, the overall structure of the present application is highly practical and has good use effect.

[0060] Furthermore, in a specific implementation, according to an embodiment of the present invention, the workpiece carrier plate 10 is made of PEEK material, and the upper end surface of the workpiece carrier plate 10 is a smooth surface.

[0061] Therefore, when the workpiece carrier 10 is made of PEEK material, it has excellent toughness and rigidity, and is resistant to corrosion, aging, wear, and high temperature, so that it has a long service life. When the upper end surface of the workpiece carrier 10 is a smooth surface, it is also convenient to quickly tear off the easy-to-tear film (not shown), so that the tearing is smooth.

[0062] Furthermore, in the specific implementation, Figure 1 As shown, according to one embodiment of the utility model, the upper end surface of the workpiece carrier 10 is downwardly opened with a plurality of slots 101 for inserting and fixing small workpieces near its outer periphery, and the middle part of the upper end surface of the workpiece carrier 10 protrudes upward to form a large workpiece supporting platform 102 for fixing large workpieces.

[0063] Therefore, when the present application is actually used, the present application is also used to fix large workpieces that need to be assembled. The large workpieces to be assembled can be fixed to the large workpiece carrier 102, so that the area in the middle of the upper end surface of the workpiece carrier plate 10 described in the present application can achieve reasonable use of space to avoid waste.

[0064] Furthermore, through the above-mentioned optimization design, the overall use effect of the present application can be effectively improved.

[0065] Preferably, in this technical solution, Figure 1 and Figure 3 As shown, according to one embodiment of the present invention, the upper end surface of the large workpiece carrier 102 is divided into a plurality of large workpiece fixing areas 1021 for fixing the same or different large workpieces.

[0066] Therefore, a plurality of identical or different large workpieces can be fixed in the middle area of ​​the upper end surface of the workpiece carrier 10 described in the present application, so that the space can be more reasonably utilized to avoid waste.

[0067] And preferably, in this technical solution, the control Figure 1 and Figure 3 As shown, according to an embodiment of the present invention, a plurality of independent vacuum channels 103 are provided inside the workpiece carrier 10, and the plurality of vacuum channels 103 are correspondingly located directly below the plurality of large workpiece fixing areas 1021;

[0068] Among them, the upper end surface of each large workpiece fixing area 1021 is evenly provided with multiple vacuum adsorption holes 104 connected to the vacuum channels 103 located at the corresponding position directly below it, and the side wall of the workpiece carrier 10 is correspondingly provided with vacuum holes 105 connected to the multiple vacuum channels 103.

[0069] Therefore, it can be clearly seen that for a plurality of large workpieces to be fixed, they are all fixed by means of vacuum adsorption, so that the fixing stability is good.

[0070] And because a plurality of independent vacuum channels 103 are opened inside the workpiece carrier 10, and the plurality of vacuum channels 103 are correspondingly located directly below the plurality of large workpiece fixing areas 1021, and the upper end surface of each of the large workpiece fixing areas 1021 is evenly opened with a plurality of vacuum adsorption holes 104 connected to the vacuum channels 103 located at the corresponding position directly below it, it can be understood that a plurality of large workpieces to be fixed are all fixed by independent vacuum adsorption, so that they can all be independently vacuum adsorbed or independently released from vacuum adsorption, and whether they are fixed or not does not interfere with each other, making the present application flexible to use.

[0071] In addition, in the specific implementation, Figure 1 As shown, according to one embodiment of the present invention, the upper end surface of the workpiece carrier plate 10 is provided with a plurality of fixing clamps 106 protruding upward on the periphery of the large workpiece supporting platform 102 and / or the upper end surface of the large workpiece supporting platform 102 for correspondingly clamping and fixing a plurality of the large workpieces.

[0072] Therefore, for large workpieces that are commonly used to be fixed, the fixing clamp 106 can be set at an appropriate position on its outer periphery according to its outer size and shape to preliminarily limit and locate its fixing orientation and fixing position, and then, vacuum adsorption can be used to fix it for a second time, so that the present application has good reliability.

[0073] It should be noted here that when the large workpiece is fixed on the large workpiece supporting platform 102, the fixed large workpiece does not block the small workpiece being fixed. Therefore, even if the fixing clamp 106 is arranged on the periphery of the large workpiece supporting platform 102, it does not affect the ability of the present application to simultaneously fix multiple small workpieces and multiple large workpieces.

[0074] Furthermore, in the technical solution, according to an embodiment of the utility model, a card slot 107 is opened downward on the upper end surface of the workpiece carrier 10, and a positioning chip 20 for tracking the workpiece transmission position is fixed in the card slot 107.

[0075] Therefore, the positioning chip 20 is connected to the computer through the network. When the present application is transmitted to a certain assembly station through the assembly line operation, the position of the positioning chip 20 can be queried through the computer to locate the station where the present application is located, so as to facilitate tracking by the operator.

[0076] Furthermore, through the above-mentioned optimization design, the overall use effect of the present application can be further improved.

[0077] It should be added that in the specific implementation, Figure 2 As shown, according to one embodiment of the utility model, the present application further includes a bottom support plate 30;

[0078] Among them, at least one of the workpiece carriers 10 is stacked and fixed on the bottom support plate 30, and the bottom support plate 30 is detachably fixed to a feeding tray 2000 adapted to slide on a conveying track.

[0079] Therefore, it can be clearly seen that when the present application is actually used, the at least one workpiece carrier 10 is loaded through the bottom support plate 30 to transfer multiple small workpieces and / or large workpieces fixed thereon, so that the operation efficiency of the present application is high.

[0080] And, continue to compare Figure 2 As shown, according to one embodiment of the present invention, the bottom surface of the bottom support plate 30 is upwardly opened with a plurality of insertion holes 301, and the Figure 4 As shown, the upper end surface of the feeding tray 2000 is upwardly protruded with a plurality of fixing pins 40 correspondingly adapted to be inserted into the plurality of insertion holes 301 .

[0081] Therefore, it is clear that when the plurality of fixing pins 40 are correspondingly inserted into the plurality of insertion holes 301 at relative positions, it is convenient for the workpiece carrier 10 to be easily fixed and also convenient for the workpiece carrier 10 to be easily detached.

[0082] In a specific implementation, according to an embodiment of the present invention, two opposite side walls of the workpiece carrier 10 are respectively provided with opening grooves 108 inwardly opened for holding / lifting.

[0083] Therefore, it is convenient for an operator to hold the opening groove 108 or for a mechanical claw to grab the opening groove 108 to lift the workpiece carrier 10 , making the present application easy to use.

[0084] It should be further added that, in the specific implementation, according to the clean-free workpiece clamping carrier 1000 provided by the embodiment of the utility model, each of the slots 101 is respectively provided with an elastic clip or a movable clip for clamping small workpieces, so that the insertion and fixing effect of the small workpieces that need to be fixed is better.

[0085] Other embodiments and the like are not described here by way of example.

[0086] To sum up, the cleaning-free workpiece clamping carrier 1000 provided by the present application, during the specific implementation, for the use of the present application, when glue and / or oily substances drip onto the upper end surface of the workpiece carrier 10 described in the present application, the easy-tear film (not shown) can be torn off regularly or irregularly, and a new easy-tear film (not shown) can be replaced to stick it to the upper end surface of the workpiece carrier 10 described in the present application, so as to reuse the present application. In this way, it is unnecessary to wipe and clean the upper end surface of the workpiece carrier 10 described in the present application, which saves time and effort in operation, and can greatly reduce the workload and labor costs of operators. In addition, the easy-tear film (not shown) used is obviously made of a thin film material, and its use cost is low, and the relative labor cost can be ignored, so that the use cost of the present application is also low.

[0087] Moreover, when the present application is actually used, the present application is also used to fix large workpieces that need to be assembled, and the large workpieces to be assembled can be fixed to the large workpiece carrier 102, so that the area in the middle of the upper end surface of the workpiece carrier 10 described in the present application can achieve reasonable use of space to avoid waste. For multiple large workpieces to be fixed, they are all fixed by vacuum adsorption, so that the fixation is stable, and because multiple independent vacuum channels 103 are opened inside the workpiece carrier 10, and multiple vacuum channels 103 are correspondingly located directly below the multiple large workpiece fixing areas 1021, and the upper end surface of each large workpiece fixing area 1021 is evenly opened with multiple vacuum adsorption holes 104 connected to the vacuum channels 103 located at the corresponding position directly below it, it can be understood that multiple large workpieces to be fixed are all fixed by independent vacuum adsorption, so that they can be independently vacuum adsorbed or can be independently released from vacuum adsorption, and whether they are fixed or not does not interfere with each other, making the present application flexible to use.

[0088] Furthermore, the cleaning-free workpiece clamping carrier 1000 provided by the present application is indeed extremely practical and has excellent use effect, which makes the present application inevitably have a good market promotion value, and the present application is also bound to be very popular and will be effectively popularized.
